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: Another really interesting physics-based module from ADDAC, the Swell models ripples in a body of water, translating the height of imaginary buoys into control voltage signals to create an organic, fluid modulation source.

Supplier's Notes:
Following ADDAC's ADDC503 Marble Physics here is a new simulation of a physical system. This time, imagine a small area in the middle of the ocean, in this area we place 4 equally spaced buoys anchored to the bottom in such a system that we can control the spacing between the buoys. Imagine we can control the elements and agitate the waters at will which in turn will make the buoys move up and down as the water surface moves.

Finally imagine the buoys would wirelessly transmit their absolute height directly to your module outputs where they would be mapped to a voltage signal.

ADDAC use a Gerstner Wave as the motor behind the two-dimensional wave generation. In fluid dynamics a Gerstner Wave is described as "a progressive wave of permanent form on the surface of an incompressible fluid of infinite depth". Gerstner waves are often used in computer graphics to simulate any type of water surface, if you've seen any animation film or computer game with water surfaces in it most probably it features a Gerstner wave generating it.

Notes: The CVADDER-HQ is a precision adder especially for adding 1V/octave (pitch-controlling) CVs. This makes it possible e.g. to transpose a sequence. Compared to general purpose CV mixers (like POLAMIX), this module does the summing of the CVs very precise (within a few millivolts), so the desired pitch is not affected.

The module offers four CV inputs where three of them are summed, and the CV at the fourth input is subtracted - meaning "transposition downwards".

This module also allows transposing the incoming CV by one or two octaves or a variable offset by buttons.

A separate output provides the voltage of the internal transposition (+1, +2 octaves / free).

If the transposition buttons are not necessary and you prefer to have a dual precision adder, take a look at the 2CVADD-HQ module.

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.

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: 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: AXON-2 is an 8HP expander module for the SQUID SALMPLE, MFX and Pamela's PRO Workout that like the AXON-1 provides 4 additional freely assignable CV inputs but additionally adds manual offset controls and 2 additional 'performance' buttons.

The addition of AXON-2 increases the Squid, MFX or Pam PRO's total number of CV inputs by 4, greatly increasing the possibilities for vast modular manipulation. Each of the CV inputs includes an offset for hands on control over parameters assigned to CV. Per assignment digital attenuation and offset via the host module is also available for fine tuning the modulation or control over parameters.

The AXON-2's large buttons are great for controlling select functions in a live performance environment or adding convenient quick navigation shortcuts when making edits. The buttons functionality and assignability are dependent on the host module. See respective manuals for details.

NOTE: AXON-2 support requires the latest firmware be installed for Pam Pro (120 or newer), Squid (187 or newer) and MFX (105 or newer).

Features
4 Additional freely assignable CV inputs for the SQUID SALMPLE, MFX or Pamela's PRO Workout

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.

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: Part of TipTop's exceptional series of Eurorack-format Buchla modules, the 264t provides four sample-and-hold circuits, plus a logic circuit designed to control polyphonic patches. Deceptively simple but surprisingly creative, like most Buchla modules.

Supplier's Notes:
Four independent sample-and-hold circuits, plus a specialized logic circuit for expediently implementing polyphonic patches.

Sample-and-hold's are essentially one-cell analog memories. They are useful for "remembering" the instantaneous value of a control voltage (a detected envelope, for example), for generating equally spaced steps from a constant slope input (as from a 281t envelope generator), and for converting any continuously changing voltage (a random voltage, for instance) into a series of discrete values.

The 264's sample-and-hold circuits have two operating modes: sample and track. In the sample mode, the value of the input is sampled and applied to the output whenever a pulse is received. The output remains at this value until the next pulse arrives. The track mode diers in that an input is applied to the output for the duration of the pulse. The output tracks the input until the end of the pulse and remains at a constant value until the next pulse.

To use the 264t as four independent channels set the separate/common switch to separate. A single CV can be set to all four channels by setting the operate/common to common and plug CV in the the back jack on the with right side.

The Model 264t includes a polyphonic adaptor, which performs the logic necessary to implement four-voice polyphony. Facilities are incorporated for fine tuning and f.m. modulating the oscillators; light emitters display the adaptor's operation.

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.

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.

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: Dnipro serve up a solid option for generating modulation signals: knob recording, LFOs or loopable random modulation, all syncable to a clock signal. Nice touches include tap tempo and slew.

Supplier's Notes:
Krait is flexible 3-channel modulation source for eurorack system. Each channel can be either a Knob Recorder, LFO or loopable Random Generator.
The module is designed to be in solid sync with your beats, so in order to work, Krait should receive steady external clock pulse. However, LFO will work without clock. All settings and waveforms will be autosaved and reloaded after power off.

Knob Recorder:

Can record pot turns, up to 8 bars loops possible.

LFO:

Tap tempo LFO with morphable waveforms and phase offset. Sync it to your beats.

Random Generator:

Syncable random with portamento and possibility to freeze and loop 16 steps.

Technical details:

6 HP

70 mA +12V

12mA -12V

0 mA 5V

42 mm deep

Voltage ranges: +5-5v, 0v+5v

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: 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: 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: 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.

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: Need an offset voltage? Of course you do, you probably need one all the time, and you can never seem to find one. Well, here's two.

Yes, the Stereo Offset boasts not one but TWO linked offset voltages, and even better, they can be independently set as unipolar or bipolar with jumpers on the back of the module. To further aid your adventure in offsetting, bicolor LEDs will indicate the current state of both outputs.

Smoothly transition between voltages to simultaneously control other functions in your system, either by applying identical voltages to two different places, or by using simultaneous unipolar and bipolar signals for advanced control over your Eurorack system.

Do the right thing - get an offset generator you will love.

Notes: Building on the familiar dual VCO core arrangement of Carrier and Modulator, Mindphaser is a complex oscillator which departs from this bit of ancestral DNA with a modern toolkit focused on searing, phase-modulated leads, percussive basslines and other-worldly effects!

A diverse palette of intermodulation and harmonic experimentation is offered through the Modulation Bus, its unique Waveshaper and the dedicated Thru-zero Phase Modulation Bus. An intuitive interface provides colour-coded visual feedback and responsive indication while performing in dimly-lit environments.

Two precision analogue oscillator cores

Precision, wide-range V/oct ramp cores, each ranging from deep subsonic to supersonic frequencies (ramp cores, and not triangular, deliver the ideal waveforms for analogue phase accumulation in the TZ-PM Bus)
Each core generates fundamental waveshapes which interact and mangle one-another through the complex Modulation Bus and TZ-PM bus
Simultaneous waveform outputs for each base shape
Dedicated button to toggle between RAMP or SAW for each core, inverting the phase of the ramp output
V/oct, linear FM and exponential FM inputs which are all independent of the TZ-PM functionality. The Carrier's FM occurs inside the core itself, separate from the TZ-PM bus.
DC-coupled linear FM

Carrier

The heartbeat of Mindphaser, focused on audio-rate generation. Drives the WAVESHAPER and TZ-PM bus. This core's frequency range spans the audible spectrum.

- An external hard SYNC IN forcibly resets the core, useful for punchy sequences, percussive basslines and drum synthesis -- or to sync to another VCO.

- Coarse and fine controls conveniently span the audible spectrum. Ranges further with external CV.

Modulator

An extremely wide range oscillator, spanning from deep LFO frequencies all the way up to supersonic sound! Four base waveforms and diverse internal routing options form a versatile palette of modulations for the CARRIER to feed on.

- Activating hard SYNC on the Modulator locks its core to the Carrier's heartbeat. The effect can be dramatic. Try this while phase modulating!

- Octave RANGE switch lets you quickly flick up and down between octaves. All the way beyond audio-rate and LFO speed octaves. Perfect for experimenting with different PM sidebands and taming the wide frequency range of the Modulator.

- Manual PW (Pulse Width) control and dedicated CV input for PWM.

Waveshaper

This isn't a classic waveshaper! Developed anew from the ground up, this waveshaper is focused on deep harmonic experimentation and audio obliteration. Each waveshaper parameter is capable of being "turned up to 11".

FOLD up to 5 octaves above the fundamental Carrier frequency. A ceiling forms at maximum, imparting additional harmonics.

FEEDBACK the waveshaped and phase-modulated audio through a signal path internal to the waveshaper.

AMPLITUDE modulation spans thru-zero, allowing for full-range ring modulation effects with bipolar CV or audio signals.

CLIP the final stage of amplitude with the switch to introduce a last stage of harmonics before the complex signal exits through the final OUT.

Switchable inverting attenuators on each CV input, for quickly inverting the behaviour of your modulation. The indicator illuminates red to tell you the attenuator has been inverted.

Two distinct waveshaping modes

A press of the shape switch toggles Mindphaser between RAMPOID (green) and TRIANGULAR (yellow) waveshaping modes.

These modes have a remarkable effect on the behaviour of wavefolding and overall character of the final complex OUT, in addition to TZ-PM Bus character.

RAMPOID mode folds more asymmetrically, with raucous, buzzing harmonic artefacts as you sweep and introduce TZ-PM

TRIANGULAR mode folds more symmetric, splitting the complex sine wave at its peak centre of the waveform. TZ-PM character is less raucous, and more smooth.

TZ-PM Bus

Thru-zero phase modulation in the ANALOGUE realm! Unlike its digital counterpart, analogue TZ-PM has its own character we've come to expect from analogue circuitry!

A dedicated, voltage-controlled phase modulation bus completely separate from the Mod Bus
Modulator's SINE wave normalled to the PM SOURCE input
SOURCE input allows you to modulate phase with any signal you patch in
Dedicated voltage-controlled INDEX (amount)
Manual phase lets you zero in (or not!) on the base phase before introducing modulation
Independent of the Linear FM circuitry in the Carrier core

Mod Bus

The internal modulation powerhouse, normally fed by the Modulator core, but external signals are patchable as well.

Select from the PULSE, RAMP/SAW or SINE output of the MODULATOR, or inject your own SOURCE to the bus.

Voltage-controlled INDEX behaves like a macro control when combined with various amounts and polarities dialled in at each CV destination.

Internal sends include the Carrier's classic Linear FM, Amplitude, Feedback and TZ-PM Index, with variable amounts and polarities!

Modulator waveforms internally feeding the Mod Bus behave unipolarly, for predictable modulation of every Mod Bus destination, without external patching. By patching in one of the Modulator's bipolar waveform outputs manually (or any external signal), you can override this behaviour.

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

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.

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: 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: The Quadigy is a complex envelope generator focused on live play.

The goal is to allow the user setting up rich, interactive and dynamically evolving envelopes without the risk of breaking up a subtle and intricate patch once on stage.

This is achieved by offering two main modes, one where full control is available and a Live mode where only the settings that are sensible using on stage are accessible.

The user interface offers an intuitive access for otherwise complex settings.

Advanced features such as automatic time-stretching, multiphase clocking and full morphing put the Quadigy in a category on its own.

Notes: CV Random is a random CV generator with 4 types of randomness and a triggerable sample-and-hold function.

Sliders allow you to set the internal clock tempo (RATE), shape the probability of triggering (PROB), blend old with new values (RND) and set the shape of all four random outputs (SHAPE).

4 different sliders

RATE

Sets the tempo of the internal clock. The CV input below the slider adjusts the clock rate, with 1V/oct calibration when the CV attenuverter is 100%. Upon each clock trigger, the RATE slider light blinks, and there is a chance for the internal random source to generate a new value.

PROB

This probability is set by the PROB slider, and if a new value was generated, the PROB slider light blinks and a pulse is emitted from the TRIG output.

RND

When the internal random source generates a new value, it mixes the previous value with a random value, with an amount specified by the RND slider.

SHAPE

The SHAPE slider sets the shape of all four random outputs. At its lowest position (0%), all outputs immediately jump to the new random value (the target value) when the clock is triggered.

At non-zero positions, the outputs interpolate between the previous and the target value, using a different behaviour for each output.

Internal random clock source

Whenever the clock activates, the RATE slider's light flashes. At the same time, there's a chance that the internal random source will create a new value, depending on the PROB slider's setting.

If it does create a new value, the PROB slider's light flashes too, and a pulse comes out of the TRIG output.

External IN & TRIG inputs

If the TRIG input is patched, the RATE slider is ignored, and the internal clock is only triggered when an external trigger is received. The PROB slider is used to filter this trigger by applying some probability.

Self-modulation

Thanks to a switch in the back of the module, you can normalize the LIN output to the 4 CV inputs and adjust the amount of modulation for each parameter with the attenuverters.

This adds another layer of randomness to your results, enabling more dynamic and unpredictable outcomes.

SHAPE Outputs

The STEP output jumps to the new value in one step at 0% SHAPE, and divides the transition into 16 steps at 100% SHAPE.

The LIN output immediately reaches the new value at 0% SHAPE, and takes the whole clock cycle to do so at 100% SHAPE, staying constant in between.

The EXP output shifts exponentially, becoming linear at 100% SHAPE, with its pace adjusted by the SHAPE slider.

The SMTH output transitions smoothly, with the speed controlled by the SHAPE setting, holding at the target until the cycle ends.

Notes: Clep Diaz is a handy and small step CV and LFO generator. In step and random modes, use the encoder to control the number of steps in the sequence; in LFO mode, the encoder controls the amplitude of the wave. Toggle the directionality of the sequence: up, down, or up/down to customize the CVs further. CD also gives CV control over the number of steps in the sequence and an end-of-cycle trigger output. Unipolar and bipolar outputs allow maximal control.
