Notes: ADSR is a four stage linear envelope with two expressive ranges. Each stage can be modified independently allowing for the creation of complex, multi-segment envelopes. Great for modulating filters, VCAs, and oscillators.

Notes: The Dual EnvVCA is a two-channel analogue linear envelope generator with two fully independent low-noise exponential VCAs. With time ranges from 30 minutes to 8kHz, it can be used as an LFO, slew limiter, ASR/ADSR complex EG, audio-rate oscillator, stereo audio/CV VCA, envelope follower, sidechain processor, and general utility module. The outputs can be attenuated, inverted, and offset without disrupting the VCA, making it a versatile modulation source.

Notes: The hands-on control of hardware meets the versatility of software. Bridging the gap between Eurorack and VCV Rack, the MetaModule includes over 160 built-in modules plus access to over 200 third-party options.

Supplier's Notes:
The MetaModule puts real knobs and jacks on virtual software modules. Step back from the computer and make music with hardware, while keeping the flexibility and expandability of software.

The MetaModule comes with over 160 built-in modules from 4ms Company, Befaco, HetrickCV, NonlinearCircuits, and Scanner Darkly, plus clones of popular classics such as the Mutable Instruments eurorack modules, fun physical modeling algorithms, and lots of handy utilities.

All of the included modules are also available on the computer using the free program VCV Rack. Whether you make patches on VCV Rack and transfer them to the MetaModule, or if you just create patches directly on the MetaModule, there are plenty of creative modules to inspire new ways to make music.

MetaModule Plugins

If the 160+ built-in module aren't enough, you can load more modules as plugins. Already there are over 200 modules in third-party plugins from Bogaudio, Valley, ChowDSP, NANO Modular, and the list is growing. 4ms have an SDK available to make it easy for VCV Rack plugin developers to convert their plugin to a MetaModule plugin. 4ms' licensing terms are non-restrictive: developers are welcome to distribute their plugin in any way they wish, commercially or not.

Mapping Knobs and Jacks

The MetaModule has 12 knobs that can be mapped to virtual knobs. Each knob can be mapped to up eight virtual knobs, and each mapping can have a different range and offset. You also can save a group of mappings as a Knob Set and switch between Knob Sets with the encoder. You also can map the 8 inputs and 8 outputs to virtual module jacks. Also, the MetaModule is a USB MIDI host, so you also can map MIDI CC, note, gate, and other parameters to knobs and jacks.

Expanders

There are lots of ways to customize your MetaModule. A Wifi expander allows you to wirelessly transfer patches from your computer. Add eight more knobs with the Knob expander, or buttons with the Button expander. A CV/Audio expander adds more high-resolution inputs and outputs, and the Gate In/Out expander adds not only gate jacks but also TRS MIDI and I2C.

Under the Hood

There are six CV/Audio inputs, two gate inputs, and six CV/Audio outputs. The CV/Audio jacks are all 24-bit, 48kHz DC-coupled, -10V to +10V. A USB-C jack accepts MIDI devices and thumb drives. Patches and plugins can be loaded via a USB drive or microSD Card, and internal flash memory lets you save patches you always want to come back to.

The processor is more advanced than anything 4ms has used in the past, and is among the most powerful processors found in Eurorack. Startup time and latency are blazingly fast.

Notes: Alan (micro Turing Machine) Shift Register Based Sequencer

The randomness of the Music Thing Modular Turing Machine, shrunk down to 6HP. Alan retains all of the same functionality as the original including the connectors for the expanders.

While this module has little to do with the original Turing Machine (by Alan Turing), it is a shift register based sequencer. You cannot program this sequencer, instead it builds random sequences that can be locked in.

Alan comes tested, calibrated and ready to bring random voltages.

The After Later Audio panel is black and gold and made from FR4. The package will include a power/ribbon cable and a one year warranty.

Notes: A 6HP version of Mutable Instruments Peaks that adds CV inputs and attenuverters for each of the four parameters.

It can be an ADSR-style envelope generator, an LFO and a drum emulator. By default, the Dead Man's Catch (DMC) firmware will be loaded, which adds the Alt ENV, ALT LFO, ALT Tap, Alt Drum modes below.

The module is calibrated, comes with a power cable, and a one year warranty.

Notes: A clever hybrid of quad VCA, function generator and more in this chunky module. Four channels of oscillators, envelope generators and VCAs, plus slew, voltage sources and plenty of CV control.

Supplier's Notes:
Four channels of function generator, oscillator, slew limiter, envelope, and VCAs. This module brings the ultimate in flexibility as it can be used as a standalone synth voice, a massive amount of modulation, or a four channel envelope generator w/ mixer. We believe this makes QARV a great first module and a great addition to the largest of systems.

All four channels have the following features:

Uni-polar oscillator mode
Attack and release time control via potentiometer and via input jack
Shape control that controls shape for both attack and release
Output attenuverter
VCAs that normal to each subsequent channel (CH1 -> CH2, etc.). So you can get a mix of all four channels out of the CH4 VCA output (unless you patch a VCA output from an earlier channel)
Channels 1 & 4

Voltage source (CH1 - 5V & CH4 - 10V)
CH1 & CH4 can be switched between IN (slew mode) and TRIG (envelope) mode
RISE and FALL gates. You can use our G&T module to turn these gates into triggers.
Channels 2 & 3:

Bi-polar oscillator mode
Dedicated IN and TRIG jacks (helpful for adding offset to a triggered ENV)
BOTH input jack to simplify patching both the attack and release (also inverts the input to give more standard pitch tracking of higher voltage equals higher pitch)

Notes: An 8hp version of the retired Mutable Instruments Grids. It is an identical functional clone, so it will behave in the same was as the full size version, and will run any firmware that runs on the full size version.

Notes: Ornament & Crime for 1U Intellijel format

This is functionally identical to the 3U version, just re-oriented to fit in 1U racks. Ornament & Crime is designed by mxmxmx.

The apps currently available in Ornament & Crime:

CopierMaschine is an enhanced version of the original quantising digital emulation of a four stage analogue shift register (ASR).

Harrington 1200 provides basic neo-Riemannian Tonnetz transformations of triadic chords, triggered by the digital (gate/trigger) inputs.

Automatonnetz combines Tonnetz transforms with a "vector" sequencer - it can be both a chord sequencer and a melody sequencer, but not of the usual kind.

Quantermain is a quad pitch quantiser for external voltages, with editable scales; it can do clocked (trigger-driven) quantising, or continuous quantising, with a latency of under 100 microseconds; it also features quad Turing Machines, May-Verhulst logistic maps or byte beats as optional, semi-random, internally generated CV sources.

Meta-Q is a dual-channel quantiser, similar to Quantermain, but also offering scale and note mask sequencing.

Quadraturia is a wavetable quadrature LFO, based on the "Easter egg" in the Mutable Instruments Frames module.

Low-rents is a dual Lorenz and Rossler (strange attractor) modulation generator, partially based on the "Easter egg" in the Mutable Instruments Streams module.

Piqued is a quad voltage-controlled envelope generator, based on envelope generator code from the Mutable Instruments Peaks module, but extending it with voltage control, additional envelope types, including re-triggering (looping) envelopes, additional segment shapes, adjustable trigger delays, and a unique Euclidean "trigger filter" which turns the app into a Euclidean rhythm generator which can output envelopes, not just gate or trigger pulses.

Sequins is a dual-channel step sequencer offering 4 "tracks" of up to 16 steps each; tracks can themselves be sequenced.

Dialectic Ping Pong is a quad bouncing ball envelope generator, based on a hidden mode of the Mutable Instruments Peaks module.

Viznutcracker, sweet! is a quad "byte beat" equation generator, which can be used as an audio source to generate curious but often interesting 8-bit noises and tunes, or which can be clocked by an external source to produce "byte beat" control voltage sequences. "Byte beats" were first described in 2011 by viznut (aka Ville-Matias Heikkila).

Acid Curds is both a chord quantiser (sometimes called a "harmonic quantiser" for external pitch voltages), and a chord progression sequencer.

References is an utility app that outputs specific reference voltages on each channel to help tune or calibrate VCOs and other modules. It also includes a high-precision frequency meter and note tuner, a high-precision BPM (beats per minute) tempo meter, and a closed-loop calibration mode.

Notes: Two independent Contour Envelope Generators in a single 12hp wide Eurorack module. These are very accurate replicas of the Model D contour generators, with identical circuitry and component values running on the correct +9.3V and -10v supply voltages of the original; so they exactly replicate the original envelope response along with all of it eccentricities. Extra features include manual trigger buttons and envelope status LED's.

The contour generators played a larger part in the sound of the Model D than many people realise. There are two factors that make them unique, firstly the exponential slope when is used in conjunction with the (near) linear slope of the original VCA which is responsible for the famous Model D "punch". Secondly, the re-trigger behaviour is quite unique, multiple retriggering increases the output level so that either the volume increases incrementally, or the filter opens incrementally with each extra key press.

AJH Synth have added independent Decay switches for each individual Contour Generator rather than the shared switch on the original synthesiser, these switches change the Contour response from AD (switch up) to ADSD mode (switch down).

Notes: The ‘Pip Slope’ (rev II) is a compact envelope and function generator. It supports both Attack/Decay and Attack/Sustain/Decay type envelopes with both direct and voltage control of Attack and Decay times. Envelope shapes can be morphed between exponential, linear and logarithmic type slopes. Envelopes can be made to loop, repeating infinitely or decreasing with time or amplitude for echo and bouncing ball type effects. An ‘End of Cycle’ trigger output further extends the envelopes functionality for both clocking and burst or fill type effects.

The improved Pip Slope adds a number of new features and updates over the original Pip whilst keeping the same size. Improvements include increased output resolution, finer control of fast envelopes, a new morphing shape control, switchable 5v or 8v maximum envelope level, additional loop modes and an additional trigger output.

Features:
Compact envelope and function generator in 4HP.
Trigger and gate inputs.
Voltage and direct control of attack and release times.
Snappy or super long envelope times – ranging approx 1ms to 7 minutes per stage.
Optional self looping ability with 3 different loop modes: Decreasing amplitude, decreasing time, and regular loop.
Shape control that morphs the envelope shape from logarithmic to linear to exponential curves.
End of Slope trigger output that fires a trigger at the end the envelope or loop cycle.
Selectable 5v or 8v max envelope level output.
Reverse polarity protection.
Skiff friendly.
Designed and Made in the UK.

Notes: The 'Quaid Megaslope' is a five stage function generator or modulator which operates in one of 3 modes; a multistage 'CZ' or 'Juno' style complex envelope, a super flexible LFO and a step sequencer with per step programmable slew or slides.

Each mode produces a varying output voltage moving from point to point across a set number of chained together stages. Each stage features a destination level, an overall rate or time to reach its destination level and a variable slope for the output path to take. As well as direct control, every stage feature voltage control of both level and rate. There are both unipolar and bipolar voltage outputs together with triggers emitted for the end of each stage and the end of a full cycle.

The Quaid Megaslope is designed to be fun, flexible and intuitive to use.

Notes: RACHAEL is an ideal companion to DECKARD'S VOICE or any other oscillator/sound source, bringing unique signal interaction and ring modulation capabilities to modular form. 100% analog, you'll find a wealth of facilities in this compact space, including full ring modulation, a dedicated VCO, a four-stage envelope with amount, and LFO.

Full-throated Ring Modulation
From tremolos to alien-invasion metallic screams, modulate any external source with RACHAEL's all-analog signal path, tunable to subtle, complex, and extreme sounds with the speed and depth controls. It's a perfect pairing for DECKARD'S VOICE or any input (via the signal input). In addition, there's both an internal reference oscillator and the ability to patch in your own external tone for even more complex and varied results.

Analog VCO
Set the oscillator to VCO mode, and RACHAEL is also a VCO with all the character of DECKARD'S DREAM and the classic CS synths that inspired it. That includes square, sine, and "csaw" waveforms -- the CSAW has the distinctive CS leading-edge pulse.

LFO
The oscillator is also configurable as an LFO, with standard sawtooth, square, and sine waves via switch. With a dedicated OSC output, you can use the LFO and ring modulation simultaneously, making RACHAEL both modulation source and creative processor.

A versatile, multipurpose envelope
RACHAEL's onboard envelope generator is more than just another ADSR. With the envelope generator amount control and switchable destinations, you can tune in an amount of the envelope to the modulation frequency, modulation depth, or both, for musical, creative sound shaping. In addition to the gate input, each stage of the envelope has dedicated CV control. And all of this comes with the distinctive vertical sliders beloved on DECKARD'S DREAM.

Notes: Buchla's legendary function generator in an affordable Eurorack module. Four generators can be linked into two pairs, with Transient, Sustained, and Cyclic modes to create envelopes, LFOs and modulation signals.

Supplier's Notes:
The 281t Quad Function Generator comprises four function generators organized in two pairs. All four generators can operate independently or can be linked in pairs to generate more complex output voltages.

Cycle jack enables the cycling of the corresponding function generator using a gate signal.

Trigger button enables the manual triggering of the function generators.

A switch selects one of three modes: Transient, Sustained, and Cyclic.

Upon receiving a pulse, a generator's output voltage ramps up to 10V at a rate determined by the sum of an applied control voltage and the setting of the attack time knob. When in Sustained mode, the voltage will stay high as long as the input pulse is maintained; when not in the Sustained mode, or when the input pulse terminates, the output ramps down to 0V at a rate determined by the sum of the decay cv in and the setting of the decay knob. At the end of the Decay segment, a transient pulse appears at the pulse output. If the 281t is in Cyclic mode, the cycle now repeats.

In the Quadrature mode, generators A and B (or C and D) operate in tandem with their functions shifted by ninety degrees in relation to each other.

Notes: In only 12hp, Axis condenses all the classical blocks for the audio amplitude management, redefining the classical envelope -> vca -> mixer path. The idea is to manipulate a sound over three axes: its length, its volume, and its place inside the stereo field.

Axis is a dual envelope generator that features an integrated VCA, a crossfader, and a voltage-controllable mixer section. The initial concept was to combine digital control over an analog VCA to closely emulate the classic Vactrol sound. After more than a year of refinement, Axis has evolved into more than just that. It offers exceptional versatility, providing a wide range of waveforms and the unique capability to simulate the natural percussive qualities of different materials. All this is in a complete analog path.

For the function generator section, we choose a faster method over the classic AD/ ADSR style: a selection of waveforms studied to give back a precise musical effect can be selected with the shape knob. The function length is independent from the actual wave shape and can be settled with the fader timeX from 30hz to 15 seconds. Also, setting the timeX fader at its maximum level will leave the VCA open.

A more typical collection of envelopes can be found in the first half of the dial. All kinds of sounds, from plucked notes to long volume swells passing through lead-friendly lines, can be obtained here.

More unusual, the last section of the knob is thought to simulate the acoustic vibration of a percussed object. Starting with a triangular envelope, from this point on, the more you turn the knob, the more rebounds will be added, simulating the natural ring of a material. Using this section at low rates can generate complex envelopes that could also be suitable for the vibrato-style AM effect. The envelope generator section includes a mode switch (cycle,trigger,hold), a trigger/gate input, an EOC trigger out, a function output, a CV for the envelope shape selection, and one CV for time.

As a cherry on the cake, a crossfader is placed at the end of the chain, blending both Axis halves. With a dedicated fader and CV control, raising it will invert the L/R output, creating nice stereo effects or moving the voices around the stereo field.

The VCA section is more straightforward: it has an audio input/output[1] and a VCA CV input[3].

You can plug the audio I/O to use Axis in its completeness and eliminate a lot of cables and mess!

Soundwise, here at Clank, we are all about vactrols LPGs, but since we knew it's not the most versatile option on the market, we came up with a different design. Blending together a VCA with a not-so-step filter, we obtained a VCA with a nice mild LPG flavor: enough to sound not so "clicky" but not too slow to inficiate really fast sounds.

By default, the envelope created by the function generator is normalized to the CV in of the VCA. Plugging a cable into the VCA in breaks the normalization, in this way you can use a different source to control the VCA and free the function generator for LFOs or modulation duties.

The range Y fader sets the strength of the envelope, but you can also see this control as a volume fader, which is nice since you won't necessarily need an additional volume for your voice after the Axis. Take into consideration that since the Axis VCA is actually a low-pass gate, lowering the rangeY fader also affects the cutoff frequency. The range fader also has its CV control to program dynamic changes to the sound. Basically, it's a VCA over a VCA that permits every note to be at different intensities. Last but not least, Range CV can also be fed by a unipolar modulation CV to obtain vibrato effects or audio rate AM modulations

Notes: Chaos is excellent for modulation purposes or as a clock multiplier/ divider, but that's only scratching the surface... It takes a different approach to writing sequences than traditional sequencers, as it is built on six touring machines combined with an effective pattern and clock generator. One of the biggest challenges in electronic music production, especially when it comes to sequencing, is finding that sweet spot between hands-on control and possibilities.

It can be frustrating because many sequencers with lots of fun and playable controls don't always pack the punch you need. On the flip side, you have those bigger menu-based sequencers with tons of options but can feel overwhelming with all the programming they require. It's designed to help you overcome these challenges and make your music-making experience smoother and more enjoyable, whether you're jamming or writing a song you want to execute live.

Typically, a sequencer starts with a blank canvas. However, with Chaos, you begin with all possibilities at your disposal and can easily narrow them down to fit your vision with just a few adjustments. This makes creating a sequence that conveys a specific mood quick and straightforward. Once you have established this initial mood, you can loop it from the last step to step 32 whenever you hear something you like. At this point, you can choose to modify the entire loop or adjust the parameters of any individual step. There is no need for extensive menu navigation; simply pressing a button and turning the encoder gives you control over parameters such as gate time, gate probability, gate width, gate ratcheting, gate swing, notes, scale, slew, and slew amount.

The LED bar continuously displays the voltage output of the selected channel, as well as the gate and each parameter's value, eliminating the need for a screen. You can save and recall the entire sequence of its six channels at any time. Additionally, there is an internal function that allows you to randomize all parameters or just a select few within a specified range, helping you discover new melodies to work with.

Chaos is an endless reservoir of tunes and is incredibly quick and powerful for composing sequences, gate patterns, or modulation. In a short time, it will become the brain of your system.

Six CV outputs can be used for a wide range of applications; everything from chaotic modulations to fine-tuned sequences can be obtained. Thanks to its interface you can quickly adjust the voltages from where the random engine picks new values and then edit them in every aspect.In addition, Slew amount, Quantization, and external sampling are available on every channel.

Thanks to its 6 gate outputs, Chaos can be used as your system's quick and effective clock manager and gate pattern generator. Chaos also provides a stable master clock (10mS to 10Sec) from a separate output and can be clocked from external devices. On every channel, you can set Probability, Width, Swing, Ratcheting, and Time as a multiplier/divider of the master clock or unquantized in mS.

You can freeze the last 1 to 32 steps of randomly generated CVs and Gates in a locked loop when you hear something you like. Loops are not static; every parameter of Chaos can be used again to change the loop behavior in a non-destructive way.

Entering sequencer mode means taking control of every aspect of the looped sequence generated by the random engine. You can change time, width, probability, ratcheting, slew, slew amount, note, note deviation, etc., for each of the 32 steps of all six channels.

Thanks to the external input, you can substitute the random generator with external voltages, transpose a sequence on the fly, and a lot more.

If you're more into generative stuff or want to add a bit of craziness to the patch, you can use the Chaos function to randomize all the parameters on a channel. A sophisticated control named entropy is available on every parameter to set the distance of the new value from the last one.

Chaos can save and recall 10 slots where you can save entire sets or preferred channel behavior. Recall can also be done with an external voltage.

Notes: Delta-V is a fully analogue dual-channel function generator, featuring a dedicated VCA and LFO cycle switch for each channel. It packs a great deal of functionality in only 10HP, and will surely find use in almost every patch.

Generate envelopes, slew gates and signals, or run LFOs with precise control over attack and decay times. Using the SHAPE knob, Delta-v can create a wide range of envelopes, from very snappy exponential curves for percussion to logarithmic thumps for bass lines.

If VCA's input is unpatched, the module outputs a regular voltage envelope. When an audio signal is patched into the VCA input, the output signal becomes the audio signal amplified by the envelope.

Sending other envelopes or an LFO to VCA input lets you modulate those modulators, quickly creating complex control voltages that go beyond the usual attack-decay envelope.

Combine this with the SUM output, which sums the two channels, and the attenuverters, which can quickly attenuate or invert the signal, and you have a whole array of signal processing capabilities.

The TRIGGER input fires a Attack-Decay envelope, while the SLEW input will affect the rate of change of the signal.

The trigger for channel 1 and 2 can be linked together, so you can fire two envelopes with one patch cable.

Each channel has an End of Cycle output, (EOC) this outputs a short trigger at the end of each envelope cycle.

The output voltage ranges from -10 to +10 volts, set with handy output attenuverters.

The CYCLE switch starts looping the envelope, creating LFO's that go up to audio rate, and that can also be used as an interesting sound source.

There are many ways to utilise Delta-V.

Challenge yourself to explore new, unconventional territories!

Notes: Mr. Phil Ter is a module that does a whole bunch of analog and digital stuff, in not a lot of HP.

Phil's digital bits are solely comprised of the envelope generator, for your envelopy pleasure.

The analogue bits, developed in partnership with the folks at Pittsburgh Modular Synthesizers, and are comprised of a voltage controlled amplifier circuit (VCA) as well as an extra juicy old-school transistor ladder filter, perfect for those of you who are not afraid of ladders or transistors.

Anyway, pair Mr. Phil Ter up with any oscillato,r or crank up its own filter section's resonance, and self-oscillate, get crazy.

Notes: Neat little interface module to help pad controllers play nicely with Eurorack. Hook up a device like a Launchpad or APC and jam out rhythms with retriggering options, dynamic control and MIDI sync.

Supplier's Notes:
Triggerpad is a dynamic trigger/gate sequencer in eurorack format on only 6hp. A USB MIDI controller with an 8×8 grid like Launchpad or APC is used to display and edit the patterns (see the list of compatible controllers). The user experience is tailored to live performance and detailed composition: dial in simple rhythms or complex polyrhythms, retrigger at audio rate, create dynamic percussions with velocity triggers or use longer pulses to create steppy modulations.

By using USB MIDI controllers that you might already have and maybe not use anymore, we avoid producing more plastic. Give your old gear a second life!

Notes: The MASTER18 is a very flexible generic CV processor.

You can think of the MASTER18 as a smaller and cheaper version of the DROID MASTER without CV inputs and LEDs, but with an integrated USB and MIDI, six additional gate jacks, two of which are inputs and four are outputs.

Details:

It has 8 CV output jacks with a voltage range from -10 V to +10 V, driven by highly accurate low jitter 16 bit DA converters:
2 gate inputs switching at 0.1 V
4 gate outputs switching between 0 V and 5 V
2 MIDI interfaces via MIDI standard B (mini jack)
MicroSD card reader and a button for reloading the MicroSD card
USB C to access the SD card from your computer or to send/receive MIDI MASTER18 comes with two interesting bonus features:
It can be connected to the Sinfonion as a follower of the Harmonic Sync.
It has an integrated tuning device for VCOs (can measure their frequency).

The MASTER18 is a good choice if you intend to just create CVs and don't need to process incoming CVs. It's perfect for building sequencers and MIDI to CV converters. MASTER18 can do almost any CV task you can imagine, such as sequencing, melody generation, slew limiting, quantizing, switching, mixing, working on clocks and triggers, creating envelopes and LFO or other fancy voltages, or any combination of these at the same time. While doing this, is very precise both in voltage and in timing.

You can attach several different DROID controller modules, such as the E4, the P2B8, the P10, the B32, the P4B2 or the M4 in order to get direct hands on access to all parameters and values of these patches.

Easily create your desired DROID patch utilizing our simple and easy-to-use editor with built in tutorials - the DROID Forge. It is available for Windows and Mac (both Apple Silicon and Intel).

The file created with the DROID Forge is a simple text file named "droid.ini" and needs to be loaded on the micro SD card that goes into the MASTER18.

Notes: Dot is a handy feature-packed tool for generating and managing rhythmic triggers in your system. It can fire drums, generate variable pulses, divide clocks, create rhythms on a fly with several twist of a knob or with deep, careful pattern programming. Both generative and manual program techniques can be combined, i.e., you can create pattern with Euclidean algorithm and then edit it in X0X style or shift it with xv inputs to a new levels of variety.

Despite of its slim form factor, DOT has 3 channels of patterns on a board and can be extended with additional DOTs, that can be chained together.

Technical details:

Size: 6 HP

70 mA +12V

7mA -12V

0 mA 5V

42 mm deep

4mS, 7v triggers

Notes: VCO:

- Tune: manual tune control (with an internal jumper the range can be set to ~ +/-1 half an octave or ~ +/-2.5 octaves)
- Oct: range switch -1 / 0 / +1 octave
- Mod: modulation depth (attenuator wired to the Mod. socket)
- Dest: switch that is used to address the modulation to frequency modulation (position FM) or pulsewidth modulation (positon PM), in centre positon no modulation
- PW: manual pulsewidth control for rectangle waveform, PW can be also modulated by the Mod. input as mentioned above
- Wave: waveform switch (sawtooth / off / triangle), the sum of the waveform chosen by this switch and the rectangle is fed into the VCF (to turn the rectangle off the PW control has to be set fully CCW or fully CW)
- 1V/Oct. (socket): external CV input for VCO frequency (1V/octave)
- Access to internal bus CV (via jumper, optional, please remove the bus jumper if this feature is not used to avoid unwanted frequency modulation as then the unused CV line of the bus works as a kind of antenna)
- Triangle core VCO, frequency range about 32Hz ... 8kHz

Balance unit:

- The balance unit is made of two VCAs which are controlled by the sum of manual Balance control and the balance CV input in the opposite direction.
- The audio input of VCA1 is hard-wired to the VCO output, audio input 2 is connected to the socket Ext.In.
- The output of the balance unit is used as audio input for the VCF
- Bal.: manual balance control, fully CCW the internal VCO is used, fully CW the external signal (Ext.In) is used, at centre position both signals have about the same level
- CV Bal.: CV input for balance (range about 0...+5V)
- Ext. In: external audio input for VCA2, about 5 Vpp level required for similar loudness as the internal VCO
- This socket is normalled to the internal VCO suboctave f/2 signal (rectangle with half the frequency), if no external signal is applied the suboctave signal is used as the second signal for the balance unit

VCF:

- 24 dB low pass
- Frq: manual frequency control
- FM1: frequency modulation depth (attenuator wired to the VCF FM1 socket, the socket is normalled to the internal Envelope signal and then FM1 controls the modulation depth of the internal envelope applied to the filter)
- FM2 (socket) : second CV input for VCF without attenuator (about 1V/octave), can be used e.g. for VCF tracking by connecting the same CV which is used also for the VCO frequency
- Res: manual resonance control (up to self oscillation)
- If the VCO is turned off (waveform switch = centre position, pulsewidth control = fully CCW or CW) and the VCF resonance is set to maximum the module can be used as a sine oscillator, the tracking at socket VCF FM2 is about 1V/octave (not as precise as the VCO but much better than most other filters)
- ~ 11 octaves frequency range (~ 10 Hz ... 20kHz)

VCA:

- Gain: manual amplitude control (initial gain), can be used to open the VCA without envelope signal
- VCA (switch): used to switch between gate and envelope as control signal for the VCA, in centre position the VCA is not controlled by envelope or gate
- Note: when gate is used the VCA is controlled directly by the gate signal (i.e. hard on/off), this may lead to clicking noise under certain conditions (especially with low VCO/VCF frequencies)
- Special control scale: exponential scale in the range from about -20dB to -80/90dB, linear scale from about -20dB to 0dB
- Remark: this special control scale results in a loudness behaviour that is a bit different from pure linear or exponential VCAs
- Out: audio output of the module (= VCA output)

Envelope:

- Gate (socket): Gate input (min. +5V), can be normalled to the bus gate signal by means of a jumper
- Att: manual control for Attack
- D/R: manual control for Decay/Release
- Env. (switch): used to switch between A/D, ADSR and A/R mode of the envelope generator, in centre position (ADSR) the sustain level is fixed to about 50%
- Envelope (socket): envelope output (about +10V)
- CVT (socket): CV input for time control, by means of two internal jumpers one can select which time parameters are controlled by the CVT input (e.g. A only or D/R only or A/D/R) and in which direction (i.e. if an increasing CVT shortens or stretches the time parameter in question)
- Envelope LED display
- Attack time range: ~ 1ms ... 5 sec (can be extended by using the CVT input)
- Decay/Release time range: ~ 1ms ... 15 sec (can be extended by using the CVT input)

Notes: The module contains two ADSR type voltage controlled envelope generators with exponential curve shapes (charge/discharge curves of a capacitor) behind a front panel with 8 HP only.

Each ADSR provides these controls and in/outputs:

- LED (displays the envelope output)
- A: manual Attack control
- D: manual Decay control
- S: manual Sustain control
- R: manual Release control
- Gate Input
- Retrigger Input
- CVT Input with attenuator (CVT = CV Time)
- Envelope Output 1
- Envelope Output 2

The output voltage range for each envelope is 0 - 10V (10V = attack peak).

The time range of Attack/Decay/Release is about 1ms to 30s.

By means of internal jumpers one can select which time parameters are controlled by the CVT input (e.g. D only or D+R or A+D+R) and in which direction (i.e. if an increasing CVT shortens or stretches the time parameter in question).

Socket CVT can be normalled to an internal fixed voltage (i.e. the switching contact is connected to an internal fixed voltage). That way it's possible to change all time parameters simultaneously by means of the CVT control.

Another jumper is used to set output 2 to normal or inverted envelope.

And another jumper is used for the normalling of Gate 2 to Gate 1 (i.e. ADSR#2 is also triggered by Gate 1).

Two more jumpers are used for the optional bus access to the gate signal of the bus for each ADSR.

Notes: Module A-147-2 is the successor of the VCLFO A-147 but offers much more features than the predecessor. The module is made of these sub-units:

- VCLFO: voltage controlled low frequency oscillator
- VCA: voltage controlled amplifier, switchable to voltage controlled polarizer
- VC delay unit: voltage controlled linear attack envelope (only one parameter: attack) for delayed LFO operation in combination with the VCA (e.g. delayed vibrato/tremolo)

LFO: The voltage controlled LFO has the waveforms Triangle, Sine, Sawtooth and Rectangle available and features a Reset/Sync input. Triangle/Sine and Rectangle are displayed by means of dual-colour LEDs (probably red/green), Sawtooth has a unicolor LED available (probably blue). The output levels are about -4V...+4V for Triangle, Sine and Rectangle. The Sawtooth level is about 0...+8V.

The CV control can be switched to attenuator or polarizer ("CV Mode" switch). In polarizer mode the CV inputs affects the frequency in the reverse manner when the CV control is left from the centre position. In the centre position CV has no effect and right from the centre the control works like a normal attenuator. The frequency range (without external CV) is from about 0,005 Hz (i.e. about 3 minutes per period) to 200 Hz (with external CV max. frequency about 1kHz). In addition a ultra-low mode can be activated by means of an internal jumper. When the ultra-low jumper is set a fixed voltage is connected to the switching contact of the "LFO CV" socket. In polarizer mode of the CV control that way extremely low frequencies (up to one hour period and more) are possible. For this a jumper has to be installed on the pin header JP6. In the factory a dummy jumper is installed on the pin header JP7 "Dummy". JP7 has no function and is used only for "parking" of the jumper. Simply remove the jumper from JP7 and plug it on JP6. JP6 is located behind the CV control.

VCA: This is a linear VCA that can be switched to "normal" VCA (i.e. kind of a voltage controlled attenuator) or voltage controlled polarizer ("VCA Mode" switch). In the "normal" VCA mode amplification +1 is achieved with about +5V control voltage. In polarizer mode the amplification ranges from about -0.5 (i.e. inverted signal with about 50% level) with 0V CV to +0.5 (i.e. non-inverted signal with about 50% level) with +5V CV. With about +2.5V CV the signal is suppressed. Details about the functioning of a voltage controlled polarizer can be found in the description of the module A-133. In this mode the VCA can be treated also a DC coupled ring modulator (similar to A-114).

The VCA of the A-147-2 has three sockets available: "In" (signal input), "Out" (signal output) and "CV" (control voltage input).

The Triangle Output of the LFO is normalled to the VCA signal input by means of the switching contact of the "VCA In" socket. If another LFO waveform (or any other signal) should be processed by the VCA the corresponding signal has to be patched to the "VCA In" socket. The VCA can be used also independently from the LFO and the Delay CV. In this case the VCA sockets In, Out and CV have to be patched accordingly. The VCA can be used also as waveshaper for the LFO signals (e.g. by patching VCA In and VCA CV to different LFO signals, if necessary via attenuator A-183-1 or offset generator/attenuator A-183-2).

Attack/Delay: The third sub-unit of the module is a simple, voltage controlled envelope generator that has only the parameter "Delay" (or Attack) available. This unit generates a linear increasing voltage that starts from 0V after each Delay Reset until it reaches about +5V. Then the voltage remains at +5V until the next Delay Reset occurs. The inclination or gradient is controlled by the manual Delay control and the Delay control voltage ("Delay CV" input). The waveform is linear, the control scale is exponential. The output voltage is displayed by a green LED and available at the "Delay Out" socket.

The manual Delay control ranges - without external "Delay CV" - from about 5ms (fully CW) up to 2 minutes (fully CCW). By means of an external voltage applied to the "Delay CV" socket this range can be extended. A rising CV shortens the delay time (behaviour like a VCO)!

The Delay output voltage ranges from about 0V to +5V. The rising edge of the gate, clock or trigger signal applied to the "Delay Reset" sockets resets the Delay output voltage to 0 V.

"Delay Out" is normalled to the VCA CV input by means of the switching contact of the "VCA CV" socket and consequently controls the Triangle level provided that no other patch is made. A typical example is the usage of a Gate signal (e.g. from a USB/Midi-to-CV/Gate interface) as Delay Reset. That way a delayed vibrato or tremolo can be realized if the VCA output is patched to the frequency CV input of a VCO (or VCF), or the CV input of a VCA.

Notes: Polyphonic sequencing from Elektrofon, the Klang allows you to program and perform chords and multi-layered harmonies. Circular clock-style display gives visual feedback and real-time indication of chord progressions.

Supplier's Notes:
«Klang» is a 4 voice polyphonic controller. It stores, traverses and manipulates chord progressions.

Overview

«Klang» is a unique take on polyphonic control within Eurorack.

Displaying chords in a circular clock-like display, and giving the user immediate control over every aspect without "menu diving" makes for an easy to use and inspiring module.

The module can store up to 99 chords, where each chord is made up of 4 voices.

Each voice is represented by a colored indicator on the clock-face which in turn is controlled by an encoder.

The indicators points to notes on the chromatic scale drawn in 360- around the clock-face.

Interface

The big grey encoder in the middle of the module lets you browse the chords - the active chord and total chord count is shown just above the encoder on the display.

The + button lets you ad a new chord. The new chord is added after the currently active chord, and the new chord is then set as the active chord.

The - button removes the current chord.

Inputs

The module has 3 inputs - 1 trigger input and 2 bipolar CV inputs.

Trigger input

The trigger input triggers a chord change.

If the direction input is unconnected, a single trigger results in a single step in the forwards direction.

Direction input (+-5V)

The direction input normalizes to a single step in the forwards direction.

You can feed this input a bipolar CV (+-5V).

Direction maps the total chord count to 5V. This means that +5V results in a single trigger progressing +n steps, where n is the total chord count.

A negative voltage will do exactly the same but resulting in backwards stepping.

0V equals no movement.

Transpose input (+-5V)

This bipolar CV lets you transpose the current chord up or down within 1 octave.

It is therefore a 5V/oct input.

The reason for this is that it is intended to be used with an analoge voltage source like the Pressure Points from Make Noise, or any other analoge sequencer.

It is much easier to fine tune a 5V/oct signal with a regular potentiometer than a 1V/oct signal.

Outputs

Each voice has a separate color coded 1V/oct CV output.

Notes: The Grand Terminal is a digital multipurpose module. Its two function generators can be used as envelopes, LFOs or VCOs. The 2 filter channels individually offer 8 modes of operation, and combined with its mixing and routing capabilities and a multi effects unit, it is not only a complete back end of a synth voice, but can also be used as a synthesizer voice, stereo filter bank or general purpose sound effects processor.

The Grand Terminal is based on an ARM M4 DSP, audio resolution 48 kHz/16Bit. Its two filter channels can be used in parallel or serial, and there is a link mode for stereo operation. The Audio inputs have individual trimmable gain stages to integrate the Grand Terminal into different production environments. There´s a soft clipping feature in order to prevent unwanted distortion. Gate A is normalized to Gate B for easy parallel processing.

Each of the filters can be set to any of 8 filter types, which are: Transistor Ladder Filter (Low Pass), Diode Ladder Filter (Low Pass), Vactrol Low-Pass Gate, Resonant Vactrol Low-Pass Gate, State Variable Low-Pass Filter, State Variable High-Pass Filter, State Variable Band-Pass Filter, Comb Filter. The filter can be controlled in 2 parameters manually as well as via CV. The outputs of this section can also be controlled in Volume and Pan position. At this stage, the unit is designed to distort in the upper third of the gain control setting.

The built-in multi effects processor features eight algorithms which can be altered in 2 crucial parameters and a possibility to crossfade between the dry and the effected signal. Its algorithms are: Hall Reverb, Shimmer Reverb, Room Reverb, Spring Reverb, Ping-Pong Delay, Tape Delay and Chorus. At the end of the audio path, there´s a Master Volume Control as well as one Mono and one Stereo output.

The two function generators can operate as AD or AR envelopes. All time parameters can be set between 1 ms and 10 seconds, manually as well as via CV. The envelopes can be individually set to loop and then act as LFOs or VCOs (following V/Oct for about 6,5 octaves). They also feature End-of-Stage Outputs.

When used in connection to the Gateway, all controls which are normally set by jumpers on the back of the module are accessible from the Gateway´s front panel.

Notes: Long-awaited sequencer module from Endorphin.es, offering four tracks (three melody CV/gate, one for drum triggers) with lots of live performance options and MIDI support.

Supplier's Notes:
Ground Control is a 42 hp Eurorack performance sequencer announced at Superbooth 2019.

The sequencer has 4 tracks: three melodic tracks and a drum track consisting of 8 drum triggers and modulation/accent output. There are also dedicated mute buttons for each track, MIDI and USB-MIDI I/O, external CV and a 2-octave piano-style keyboard.

The keyboard serves for playing the melodies as well as entering the menus - in that method the module eliminates tedious menu diving.

Each track can contain 24 patterns, which can be played separately or chained together in any order. All those tracks are organized into 24 projects. The number 24 is associated to the 24 letters of the Latin alphabet.

Ground Control features a very stable internal analog and MIDI clocks preserving low jitter operation, which is crucial for tight sequencing.

The patterns are entered either in 101-style step input or live recording and can be adjusted using the 303-style editor.

The drum sections features a X0X-style sequencer.

Notes: Great value from this versatile percussion module, built around a noise generator and four linked envelope generators, each with its own VCA. Generate hi-hats, envelopes, shape drums or create modulation sequences.

Supplier's Notes:
Ricochet is a compact, fully analogue module featuring four interconnected decay envelopes, each with its own VCA and an integrated noise generator.

The module's design is inspired by the way skipping stones bounce on the water, creating a versatile tool for crafting percussive sounds.

The exponential envelopes are specifically designed to generate dynamic percussive tones. The unique linking function connects the end of one envelope's decay to the trigger of the next, enabling the subsequent envelope to activate once the previous one ends. This innovative feature allows you to create ratcheted envelope.

A front-panel trimmer lets you adjust the threshold for triggering subsequent envelopes, while a rear header enables connecting two Ricochet modules together, or linking the last envelope to the first. This feature transform the Ricochet to a weird sequencer where the steps length depend of the decay times.

Since Ricochet is fully analogic, trig inputs are velocity-sensitive, responding to a standard gates but also allowing attenuation to modify the envelope's velocity (you can play with the dynamic of your sound by attenuating the trigg input. Ricochet is also perfect to play with drum pads).

Each VCA features a gain control that can be pushed to achieve subtle saturation.

All envelopes and VCAs have separate outputs, but there are also mixed audio and envelope outputs. When an individual output is connected, it is removed from the mix. The decay modulation inputs are normalized between each other.

Last but not least, an analogue noise generator is normalised to the first input, so you can use ricochet on it's own to create hi hat kind of sounds

Main features:

- Fully analogue design so everything is responsive to the amplitude
- Unique linked envelopes feature
- Compact 4 envelopes 4 VCAs module
- Linkable to a second ricochet or looping back the last envelope to the first one

Some applications:

- Envelope generator
- Drum shaper
- Hi-hat
- Clap envelope shaper( with short ratcheted envelopes)
- Envelope sequencer
- Trigg delay
- Burst generator

Technical details:

- Fully Analogue design
- 14hp
- Skiff friendly
- Reverse power protection

Notes: USTA is a 4×4 tracks sequencer for voltages and gates with variable stage duration, designed to quickly see and edit multiple voltage relationships in real time.

Variable stage duration means that every single stage duration can be individually set in relation to the clock, instead of being constrained to a one-to-one ratio (i.e. one stage per every clock impulse).

4×4 tracks means that every stage can store and generate up to four separate voltages (two CVs and two gates), and that up to four independent stage sequences can be arranged into as many different tracks.

Its architecture is based on an array of 16 'Stages' which form a 'Pattern'; 16 patterns form a 'Track', and four tracks form a 'Project'. Within each track, each stage can provide two gates and two CVs, and a wide set of options is available to define and modify the value of each output ('Layers') and the way it is played ('Colours').

Every Stage is related to a dedicated stepped encoder for quick and intuitive editing, and all the 16 encoders are arranged in an oval layout with a circular playhead. Every encoder is surrounded by a ring of 16 LEDs and a RGB led, to provide a visual feedback of the current setting of that step basing on the layer you are working on (like raw CV, quantized CV, length, gate...) and the way it should play depending on the RGB colour.

Notes: Pretzel Logic is a 4 bit to 16 step addressable analogue sequencer which outputs gates. Each of it's 16 steps can be addressed in any order for ultimate creative flexibility. It pairs nicely with Polygraf, High Towers and Akropoli; together they make a powerful combination.

It features 4 address inputs, 1, 2, 4 and 8, each of which has an associated input socket as well as a 3 position state switch which allows each address input to be held high, respond to input signals, or held low. Each input has two status LEDs. The red LED displays the signal present at the input socket, while the green LED displays the status of the address input. The combination of signals present at the input sockets, together with the positions of the state switches allows Pretzel Logic to have 16 different output states, numbered from 0 through to 15. The output state of Pretzel Logic can be ascertained by observing which of the 4 address inputs are high. So, for example:

- If no green status LEDs are on, Pretzel Logic is in output state 0

- If green status LED 4 is on, Pretzel Logic is in output state 4

- If green status LEDs 1, 2 and 4 are on, Pretzel Logic is in output state 7

- If green status LEDs 2 and 8 are on, Pretzel Logic is in output state 10

The input sockets may be addressed by various external modules, for example:

- FC Pocket Calculator, FC High Towers, or similar clock dividers with multiple outputs from other manufacturers.

- FC Polygraf or similar grid editors from other manufacturers.

- FC Little Melody, Akropoli or similar.

As Polygraf is capable of storing many user patterns which themselves are selectable by CV, multiple chained patterns are possible. Furthermore, we accept that users will discover their own unique combinations of FC and third party modules to address Pretzel Logic, always bearing in mind that at any time the status of any of the 4 input sockets may be overridden by the 4 state switches. Pretzel Logic may be latched manually via the Latch toggle switch, or externally via the Latch input. When Pretzel Logic is latched, the last output state to go high is held until Pretzel Logic is unlatched.

Notes: Chris Huggett, chief designer at EDP came up with a novel little circuit for the filter envelope of the Wasp, based around half a CD4013, half a CD4066 and half a LM3900. It was an A/R generator with looping option which would proceed through its whole cycle from only a trigger input. He further developed the circuit for the filter envelope in the Gnat to use just one knob to provide a range of attack envelopes when anti-clockwise (from 12 o'clock), and a range of release envelopes when clockwise (from 12 o'clock). 12 o'clock gives a very short symmetrical blip. As you can build two of these with a CD4013, CD4066 and LM3900, Frequency Central have provided both a two knob version and a one knob version, each has its own place.

Both envelope outputs are 0V to 5V.

Notes: ADSR (Attack-Decay-Sustain-Release) is a module designed to generate a voltage, which acts as the envelope with the adjustable stages. This envelope, generated in response to the incoming gate signal or manually pushed button, can then be used to shape the sound amplitude via VCA, modulate filter's cutoff frequency or any other parameters expecting CV control.
It features exponential Attack, Decay and Release stages, switch to select fast/slow operation mode, push button with led indicator to manually activate the envelope.

Notes: A unique analogue percussion module, based on principles from the legendary 909 twisted into new sonic territory. Capable of everything from classic kicks and snares to more experimental hits and complex VCO effects.

Supplier's Notes:
A machine is born

The Machine began as a quest to create a rich-sounding eurorack snare drum synthesis module to complement the existing Mutant Drums. The project quickly became too large and costly to justify the module being capable only of snare drum sounds. So, the decision was made to learn from the architecture of the TR-909's snare and kick circuits, in order to develop a module capable of generating multiple forms of analogue percussion, and various other effects.

Like the other Mutant Drums, the Machine has its roots in classic analogue percussion synthesis. Even though it can create totally alien sounds, it still has the capability to deliver those classic 909 house snares and kicks if you want them. There are no microcontrollers in the Machine. The signals and waveforms are all generated by discrete components and ICs, for a distinctly analogue sound, and user experience.

Features

Microcontroller-free analogue percussion synthesis engine
Unique Inverter Core oscillators form the MEMBRANE. Each analogue oscillator has three waveforms to select from
Capable of synthesizing everything from heavy-hitting bassdrums to classic 909-style snares and other complex timbres
Modular design gives the Machine many auxiliary purposes, great for modular sound design of many varieties, and not just percussion
The SNAPPY section is comprised of a voltage controlled noise oscillator, for modelling the noisy part of drum timbres
Both MEMBRANE and SNAPPY elements have an external input for replacing the built-in sound sources, opening up many avenues of possibility
13 control voltage and audio inputs, for a fully modular drum experience
7 audio and CV/gate outputs for maximum integration with other modules
Dedicated outputs for each WAVE and NOISE oscillator mean you can use the Machine as a complex VCO in your system, when not synthesizing percussion
Waveform scanning feature generates complex timbres from analog waveforms
The MEMBRANE's waveforms can be scanned through automatically by the wavescanner's voltage controlled clock generator, or an external clock or VCO can be used
SCAN FREQ CV forms a unique form of timbre control, making the Machine act like a complex oscillator at its WAVES output
The ENABLE input allows you to gate the wavescanner on and off with a CV or gate signal

Notes: Kermit is a 4-channel programmable supermodulator with morphing wavetable generator and internal modulation matrix. Four channels operate as LFOs, audio rate oscillators (with 1v/octave response on two channels), 1-shot envelopes, random voltage generators, or sample-and-holds, all responding to manual control, external control voltages, or synchronization to the module's master tap tempo clock. Designed for maximum patching power in small systems, Kermit carries an unmatched functionality-per-HP factor with an easily readable display that shows parameters in their real-world units.

The module has a 16-bit DAC to accurately render subtle changes of voltage at extremely low frequencies. The oscillator mode is best suited for bass frequencies, and the waveform "character" modes restrict the morph behavior or degenerate the audio to a minimum of 8 bits with limited horizontal resolution, like the Konami SCC chip used with the MSX computer. The tap tempo facility features an input jack and a manual button. The tempo is shown on the OLED display in BPM. The relevant units (hertz, seconds, volts, etc) or selected waveform of each channel are contextually shown on the display as the user programs the module.

Three parameters on each channel can be modulated: frequency, amplitude, or waveform. Both external CV input and internal cross modulation are programmable with hotkeys. For example: assign the output of Channel B to morph the waveform of Channel A by holding the Channel B button while turning the Channel A Waveform knob. All channels have manual control of frequency (coarse and fine), phase, wave bank, waveform morph, and amplitude. Channels A and B have full controls, C and D have single knob controls with deep parameters accessible by hotkey combinations. Still deeper functions are accessible through the Mark III menu system.

Kermit has a microSD card slot for loading custom waveforms, like its big brother Piston Honda. The SD card accepts one .WAV file in WaveEdit format (free software editor) containing 64 waveforms, also compatible with several other Eurorack modules. When loaded into Kermit, the waveforms are organized into 8 banks of 8 waveforms each. Each oscillator can select any of the 8 banks, and the 8 constituent waves can be smoothly morphed from one to another.

The Mark III morphing preset manager is in full effect on Kermit. The discrete preset mode quickly and reliably recalls all parameters in response to triggers or CV, accessing the true power of the module as detailed, carefully programmed settings are effortlessly loaded and changed. The morphing mode causes delightfully unexpected variations of the basis preset.

Insert a master clock signal and you're ready to go. Kermit is a reliable provider of endless rhythmically coherent modulation voltages and a reasonably competent "voice module" providing most common synthesis functions on each channel with an internal modulation matrix.

Notes: Successor to the excellent Metropolis, the Metropolix is a performance-focussed step sequencer with some really neat features, including modulation and sub-sequences in Loopy mode.

Supplier's Notes:
The Intellijel Metropolix is a unique and powerful Eurorack format musical sequencer. With an abundance of hands-on, tactile controls and a wealth of modulation possibilities (both internal and external) you can quickly and easily create infectiously musical sequences that are never boring. Even the simplest riff can be brought to life with seemingly endless options to create variations or real-time manipulations. Equally at home in the studio or a live improvised performance, the Metropolix is sure to become a staple source of fresh ideas and killer riffs in your creative process.

Width: 34HP
Depth: 25mm
Power: 95mA @ +12V 10mA @ -12V

On first blush, it appears to be a simple 8-stage sequencer - but there is far more functionality than first meets the eye:

There are two tracks (TRK 1 and TRK 2) that are variants of the single master pitch/gate sequencer, which is programmed via the PITCH sliders, PULSE COUNT and GATE TYPE switches. Each track interprets the master sequence in a variety of ways - creating complementary sequence variations that enable you to generate counterpoint, polyrhythms, and all manner of sonic movement (both subtle and extreme). Each of these tracks has its own playback ORDER, sequence LENgth, clock DIVision, SWING amount, SLIDE time, and track GATE lengths. Other track-based sequence variables are accessible from the TRACK MENU, and include Pitch Slider inversion; sequence note range; track transposition; and more. In addition, Tracks 1 & 2 both have multiple lanes of per-stage playback parameters, including: GATE override; PITCH override; RATCHet count; PROBability of playback; ACCUMulating transposition, and a dedicated CV lane. Each stage also has a SKIP feature, and a pitch SLIDE option.

8 separate and individual MODulation lanes are accessed via the MOD button. Each MOD lane has 8-stages of modulation values and its own playback ORDER, LENgth, and clock DIVision; and each lane is routable to one of Metropolix' two assignable outputs or to dozens of internal destinations, allowing for some sophisticated and powerful self-modulation.

A trio of AUX inputs allows for external modulation of user-assignable sequencer parameters for even greater variation, while two assignable CTRL knobs give you direct access to the parameters you want to adjust most frequently during a performance. With dedicated Pitch/Gate outputs for both Track 1 and Track 2; two totally user-assignable outputs (A and B); and internal MOD routing, Metropolix features a wealth of patching opportunities.

Metropolix also features a Loopy mode, allowing you to instantly play back short sub-sequences, or even "play" the stage buttons directly (like a 'keyboard').

Metropolix stores up to 64 preset configurations (in 8 banks of 8 presets), and all live settings are stored in EPROM, ensuring that your Metropolix will always power up exactly as you left it - even if you haven't saved them to a preset. By default presets can change all the structural (menu-based) elements of your sequencer without overwriting the front panel controls, but full recall is also available.

The operation of the Metropolix is optimized for live performance and jamming, with quick access to all the most important performance parameters, and the ability to greatly affect your sequences with a single slider or switch.

Notes: The most complex modulator is you. The Planar 2 puts macro control over six outputs - including a quad panning mixer - into your hands with a buttery smooth joystick. Record up to 30 seconds of your own movements, stretch it or mangle it with scan mode, use a trigger for playback, or just loop it - synced or not. Add yourself to your patch.

With its smoothly responsive precision joystick, Planar 2 facilitates hands-on vector control of two entirely independent sets of outputs (quadrants A-D, and axis X/Y), plus the ability to capture and playback your gestures. Recording your joystick movements enables the creation of organic and complex envelopes, wild and wobbly LFOs, or extended sonic evolutions. It mixes, morphs, routes and pans audio inputs; triggers gates; outputs control voltages and is itself, CV-controllable. Planar 2 puts the 'joy' back in 'joystick,' and the 'fun' back in 'function generator.' Its multitasking and tactile interface makes it a flexible and unique control device, no matter what your musical genre.

Notes: Super-versatile quad envelope generator and LFO source from the Vancouver Eurorack brand. All CV controllable and with tons of shaping options.

Supplier's notes:
The Intellijel Quadrax consists of four independent, CV-controllable channels, each of which can be configured to perform any one of the following functions:

- An AD (Attack, Decay) envelope
- An AHR (Attack, Hold, Release) envelope
- A cycling envelope (resulting in a unipolar LFO)
- A pulse burst generator (Finite repeated functions that ascend or descend in amplitude)
- A morphing, bipolar beat syncable LFO

The envelopes all feature a continuously variable response curve, ranging from logarithmic through linear to exponential, and each stage can be as snappy as 0.3 ms to as lengthy as 20 seconds.

When set to Burst mode, the channel generates a rising or falling burst of pulses, with full control over the length of the pulse burst, the number and shape of the bursts within it, and whether the bursts increase or decrease in amplitude over the burst.

AD, AHR, Cycling and Burst modes all feature a user-selectable maximum output level of either 5V or 10V.

LFO mode offers control over the frequency and waveshape, while providing a unique morphing feature that creates numerous variations of the selected waveshape. LFOs can be either free-running or beat-synchronized using the channel's TRIG input.

Channels can be chained together to create complex multi-stage envelopes, with each channel triggered by the previous channel's trigger input, end-of-rise, or end-of-fall. This enables multiple function generators to fire simultaneously, or it enables the creation of complex multi-stage envelopes by allowing the linked function to fire either at the end of the previous function's rise time, or at the end of its fall time.

Four freely-assignable, step-attenuverted CV inputs are capable of modulating any or all of the various parameters across all four channels using the built-in CV matrix, and built-in attenuversion for each assignment.

Quadrax remembers its current state (Mode and CV assignments, channel links, etc) and retains that state even if power is removed, meaning Quadrax will always turn on in exactly the same state as you last left it.

Notes: Scales is an 8hp dual-channel note quantizer and step sequencer. Fundamentally, it takes an input voltage, quantizes it to notes in a user-defined scale, and sends that quantized voltage to an output, where you can use it as a melodic pitch source for oscillators or any other module that expects to see discreet note values at its input.

Scales goes far beyond the fundamental, allowing you unprecedented control of the pitches and intervals hiding inside your control voltages; turn LFO's into arpeggiators; random voltages into harmonic counterpoint; and unquantized external CV sequencers into chromatically tuned note sequencers.

Quantization can be locked to an incoming trigger. There are a number of trigger output options as well, ranging from no triggering (good for pitch shifting drones); through triggers that sync with either of the two outputs (or both); to a trigger or gate transmitted in sync with one sent to the module's TRIG input.

Shift:

Scales features two independent outputs, enabling you to create shifted harmonic intervals within your chosen scale using only a single pitch input. Using the SHIFT input you can modulate changes on OUT A and/or OUT B.

You can also use the shift input to switch between scales or to change the root of any existing scale pattern or split Scales into two quantizers - each conforming to a common scale, but fed entirely different voltage sources.

Sequence:

Scales also features a 128-step SH-101 style step sequencer (complete with storage for up to 35 fully programmable patterns) - allowing you to feed OUT B with sequenced notes and rhythm patterns, while OUT A continues to function as a standard pitch quantizer for external voltages. You can even sync the sequencer to quantizer events on OUT A.

Notes: The Shifty is essentially a combination of four sample and hold stages, a sequential gate and sequencer controller. This collection of functions allows for some specific and useful utility application.

One of the primary uses for Shifty is to take a monophonic sequence source and route each new note of the sequence to up to four different synthesizer voices in a specific pattern. In this way you can create pseudo polyphonic sequences since each voice can be triggered to play and sustain while the next voice int the sequence gets triggered. Another term for this is hocketing.

The other main application of the Shifty is to function as an Analog Shift Register. In this mode each new gate input received causes the current set of pitches to be shifted to new output locations as a new one is added and the oldest one is replaced. This can be an interesting way to create chords that are up to four stacked notes when used with a pitch sequence source that has a harmonious series of notes (e.g. a pentatonic scale works really well). Even just using two of the outputs will yield very interesting melodic interplay and is an excellent way to make a simple sequence much more complex and interesting.

In a more basic way the Shifty could be used as a simple Sample/Track and Hold module or as a sequential gate.

Notes: Tangrams

Push (or Pulse) the Envelope

Snappy, classically analogue envelopes with visually intuitive controls. Add a powerful, cv controllable cyclical gate generator, integrated VCA, and trigger buttons -then double it-now you've got Tangrams.

Tangrams, like the Dual ADSR before it, is a dual analogue core-envelope inspired by the Roland SH-101 / System 100m design with several enhancements. Taking further inspiration from trapezoidal function generators like the one on the EMS Synthi, Intellijel have added a voltage-controlled pulser circuit to link the triggering of two envelopes - allowing for delayed one-shots, cycling organic envelopes, and more. In addition, Intellijel added two VCAs for level control of each envelope, or alternatively, direct injection of the signal you'd like to envelope - freeing up your other VCAs.

The Pulser

The Pulser can be thought of as a way to set both a gate ON time (T1) and an OFF time (T2). In this way, you could configure a cycling ADSR that has a gate time that is different from the interval between gates. Alternatively, you can create a sequence where ADSR2 is triggered by a delayed amount of time after ADSR1 is triggered (either cyclically or in a single shot sequence). The panel switches for routing or disabling the pulse sources allow for even more complex combinations of control beyond these examples. This special combination of functions can yield a plethora of interesting and organic envelope and gate patterns to be created; cyclical and single shot.

Notes: ASCOLTA is a dual high fidelity input preamp with envelope follower and peak detector output for each channel.

Ascolta consist of two individual high quality preamp connected to an envelope follower and a peak detector output.

On the back of the module you can select the behaviour of its internal normalization when no cable is plugged into I2:

S: the first input I1 will accept stereo 3.5mm standard cables from any source and split L and R to output O1 and O2 respectively. This way you can directly amplify stereo signals without the need of external splitters and regulate the gain of each channel individually.

G: the second amplifier will double the amplification of the first totalling a gain range of 80dB - 10.000x.

Envelope E and peak P outputs are strictly related to the gain level of their corresponding amplifier and will follow the dynamic of any input plugged.

Features

Two high quality 40dB amplifiers.
Customizable internal normalization.
Envelope and Peak output following the input signal
Audio graded potentiometers.

Notes: Clever sequential signal processing from Joranalogue, capable of a range of functions including toggling signal muter/attenuator, clock divider, rotating shift register or programmable voltage bank.

Supplier's Notes:
Sequencers, sequential switches, counters, analogue shift registers... Modular synthesisers provide a wealth of creative sequential functions for controlling and processing signals. Choosing which of these to include in a system can be a bewildering task.

Except when you don't have to choose. Step 8 represents a new type of modular building block: a sequential tracking/sampling register, which can be configured to provide any of these functions, and many more.

At its heart lies an analogue 1-to-8 signal switch feeding an octet of high-stability track/sample-and-hold stages. Each of these has its own analogue output with an attenuation slider, in addition to a gate output. LEDs visualise the status of each stage in real time. The switch can be controlled sequentially using the built-in 8-step counter, or addressed directly by an analogue control voltage (CV).

Numerous advanced circuit techniques are used to avoid the issues that often plague analogue switching and memory modules. The result: totally transparent signal paths with low noise, distortion and voltage 'droop', yet high bandwidth and precision.

Add to this the ability to 'mute' the inactive stages, pause the counter, reset it, change its direction or even shift the stages on each step, and the possibilities quickly become near-endless. A scanning output takes things even further, particularly making sequencer or addressed voltage source use easy and intuitive.

For those who are feeling adventurous, there are always more applications to try: configurable voltage mapper, hocketing controller, clock divider, graphic waveshaper, multi-output analogue downsampler... Discover a new world of sequential synthesis with Step 8.

Notes: Random rhythm generator

Joey is a Eurorack module that generates random gate sequences. It is the offspring of Skippy (Kaona's polyrhythmic sequencer), without simply copying it: it's a very straightforward module that provides unexpected yet controllable sequences.

It offers three main modes:

Random

For random triggers controlled by an internal speed or an external clock.

Fractal

A unique algorithm sprinkled with 5% chaos, creating evolving and surprising patterns.

Euclid

Generates four different Euclidean patterns for complex and evolving rhythms.

Each mode has three adjustable parameters set via a clickable encoder: speed, a mode-specific parameter (probability, fractal root, or Euclidean pattern), and gate length. An external gate input can take over to synchronize speed. A PLAY/STOP button instantly suspends or restarts the gates.

Notes: Skippy Exp is a tiny module in 2HP that adds "Play/Stop" and "Reset" functions to Skippy, either via a button or a CV input. It cannot operate independently; you absolutely need Skippy to use it.

For those who don't need the live adjustments offered by Skippy Live (or have run out of space!), Skippy EXP still provides two essential functions for dynamic performance.

This module cannot operate alongside Skippy Live, which already has these two functions. It can be placed either to the right or left of Skippy. The connector to link it to Skippy is included. This module does not need to be connected to power.
