Synth modules

Notes: Really smart integration of macro controls for Eurorack, based on the original design by Emblematic Systems. Assign settings to eight CV outputs then morph with the crossfader or record movements to manage presets or set up complex real-time modulation. Can also operate as Catalyst Sequencer.

Supplier's Notes:
The Catalyst Controller is a macro controller with eight precision CV outputs and a responsive crossfader to morph between scenes. A scene is a snapshot of up to eight CV outputs, like a modular preset. Traverse a "pathway" composed of multiple scenes using the crossfader or an external CV signal, or immediately jump using the scene buttons. Record CV and slider movements, and play recordings back via a button or external trigger.

Each output has sub-millivolt precision and a maximum range of -5V to +10V. Channels have an adjustable morphing curve, can be quantized to common scales, restricted to a particular voltage range, or set to output gates.

Whether used as a CV preset manager, seamless transition generator, chord sequencer, CV recorder, or experimental CV playground, the Catalyst Controller puts control of your modular at your fingertips.

The Catalyst Controller can also turn into a Catalyst Sequencer! Hold down a special button combination to change between controller and sequencer modes. If you end up liking the Sequencer more, you can even remove the double-sided faceplate, flip it over, and re-install with the Sequencer artwork visible.

Based on the original Catalyst module from Emblematic Systems.

Pairs with: 4ms Catalyst Sequencer

Notes: The Catalyst Sequencer combines a traditional clocked step-sequencer with an unconventional phase-based sequencer to produce a new paradigm in sequencing. Eight precision CV sequencer channels can be simultaneously driven by a clock, a phase CV, or scrubbed manually with the crossfader.

Each of the eight channels has its own sequence length, quantizer, transposition, clock divider, randomization, voltage range (max -5V to +10V), and selectable CV (precise 16-bit resolution) or Gate mode.

Phase-based sequencing is an advanced form of sequencing where each step is selected by CV. The Catalyst Sequencer has a smooth, responsive crossfader that scrubs the sequence, playing it forward or backwards to track your motions. Patching in a CV signal will do the same: a ramp-up CV plays the sequence forwards, a ramp-down plays it backwards, a triangle plays it ping-pong, and complex waveforms generate new interesting rhythmic and melodic patterns.

The Catalyst Sequencer can also turn into a Catalyst Controller! Hold down a special button combination to change between sequencer and macro controller modes. If you end up liking the Controller more, you can even remove the double-sided faceplate, flip it over, and re-install with the Controller artwork visible.

Notes: The 2CVADD-HQ is a dual 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 three CV inputs for each of the both units; the first unit has an additional fourth input where the CV is subtracted - meaning "transposition downwards".

If you would like to have transposition buttons to shift by one or two octaves (or a free offset), take a look at the CVADDER-HQ module.

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: Neatly implemented performance mixer with four stereo channels. CV control of level and pan, two pre- or post-fader stereo send busses, quiet mutes and cueing via a front-panel headphone socket.

Supplier's Notes:
Four channel stereo production mixer

Mixer section

Each channel has the following:

Stereo or mono - Each channel can be treated as a stereo channel or a mono channel with two summed inputs.

CV inputs for both panning and level control

Two send buses - You can route each channel to one of two send buses. Each send bus is stereo. You can choose if you want the send to come before or after the level/panning controls.

Mute - The mute has both latching mute (up) and a momentary mute (down). The mute uses a capacitor to slow the turn off and on of the mute action. So it is mostly click-less, but you may find an occasional pop.

Cue bus - You can route each channel to the cue bus.

Mains Section

Two stereo sends outputs
Two stereo returns - which can also be used to directly insert into the main mix.
Main stereo outputs - level controlled with the slider and stereo VU meter.
Main mono output - summed output of the main L&R. If you are after an 8ch mono mix, you can use each channel in stereo mode, use the level control to control the level and then pan control to control the levels of the two channels.

Cue Section

1/4" Headphone jack along with level control
Fader control to listen to the main mix, cue mix, or an adjustable mix of the two.
Expandable

Bartenders can be cascaded to create 8ch, 12ch, or 16ch mixer. The main level is what is sent the main level control can act as a group control.

Barbacks can be added to add 2ch to your mix. Barbacks can also be cascaded enabling up to a 16ch mixer configuration.

Send-VCA can be added for CV control of the level of the send.

DVCA, Cast Iron, Mingles, and USB-2CH can all be connected with Dupont cables (aka female to female breadboard cables) via pin headers on the back of the modules. Connecting the in and out pins will send/receive the audio into the next module.

Width: 24hp

Notes: Dual three channel voltage controlled panning mixer

Mixer section

Channel 1 and Channel 2 are three channel mixers with potentiometers to control level of three different inputs for each channel. Each channel then has a potentiometer to control panning as well as CV control for panning and level control

Panning and VCA

The VC panners are equal loudness panning and the VCAs for each channel are linear response.

Built-in LFO

There is a built-in LFO that is normalled to the panning CV input of each channel. CH1 gets the standard LFO and CH2 gets an inverse, enabling alternating channel panning. The default is to use a TRI wave for the LFO, but there is a jumper on the back to switch it to SQU.

Width: 12hp
12V: 140mA
-12V: 120mA

Notes: This is an expander for Bartender and Barback, enabling CV control of the level of the send bus of up to 8 channels.

Each section of four jacks has a cable to connect to the mixer modules. To get 4 channels to work with Barback you want to connect it to the last Barback in the chain of two. It will then pass along channels 3 & 4 to the next Barback.

Notes: Two channel USB module.

Standard Mode - Send two channels into your USB device and receive two channels from USB.

Insert Mode - Send two channels to your USB device and get a copy of the sent signal in the outputs.

Toggle between the modes via a pair of jumpers on the back. The USB-B to USB-A cable is provided with the module. Why use the cutting edge USB-B? I felt the jacks were way more sturdy than mounting USB-C jacks vertically.

Expandable - Bartender, Barbacks, DVCA, Cast Iron, Mingles, and USB-2CH can all be connected with Dupont cables (aka female to female breadboard cables) via pin headers on the back of the modules. Connecting the in and out pins will send/receive the audio into the next module.

A characteristically unique take on mixing from Buchla, with six mono inputs and a built-in mic/guitar pre-amp. Each channel can be cued to a monitor mix, while the first and last channels also include voltage-controlled panning.

Supplier's Notes:
The Tiptop 207t is a modern reimagining of the classic Don Buchla 207 Mixer/Preamplifier from the 1970s 200 Series. This stereo mixer comes with a built-in preamp that allows you to boost external instruments and microphones, making it a versatile tool for any modular setup. The 207t also features a six-channel mixer with a variety of signal routing options, including the ability to route channels to the monitor and L&R signal outputs, with per-channel control over loudness and panning.

Each channel has a Mon switch that sends the channel's signal to the monitor outputs, which are always full-volume and summed to mono, making it useful for basic monitoring applications or rudimentary mixing. The Prog switch sends the signal to the L&R signal outputs, with loudness controlled by the Level Adjustment slider and panning determined by the Channel Assignment knobs. The first and sixth channels offer voltage control of panning; these channels are hard-panned when no CV is applied.

The preamp section features a 1/4" input and multiple gain settings, making it suitable for use with external line level instruments, electric guitars, or dynamic microphones. The continuous amplification control provides added flexibility for your audio needs. Finally, the Expansion In is a stereo input that sums to the left and right main outputs, which is great for chaining multiple 207t modules or adding another stereo source at the final output.

While the 207t's functionality may be simple, it is an essential part of any 200t system, serving as the glue that holds everything together. The Tiptop 207t is a fantastic mixer/preamp option that delivers quality sound and reliable performance.

Buchla 207t Features

Mixer/preamp module based on Don Buchla's original 207 design
Six-channel mixer with per-channel level control and panning
Voltage-controllable panning on channels 1 and 6
Manual panning on channels 2-4
Program switches can act as channel mutes for main outputs
Mon switches route signal (in mono) to Monitor output
Expansion input useful for stereo chaining and more
Re-designed preamp for high audio fidelity
Preamp suitable for use with external instruments, electric guitars, dynamic microphones, and more

Eurorack module
28hp wide

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: Expander for the DROID with 4 pots and 2 buttons

The P4B2 controller provides 4 potentiometers and 2 push buttons for free assignment to any of the DROID's parameters.

Each potentiometer outputs a value between 0 and 1 and can be used for controlling every aspect of the functions of your DROID patch (configuration), such as the speed or depth of an LFO, the pitch of a sequencer step, all aspects of an envelope, clock division and multiplication and much much more.

The buttons can be used as momentary or toggle buttons, if you like with three or four states. Or you can group several buttons together so that they work like "radio buttons". Buttons can be used for various tasks like switching between different behaviours, selecting wave forms, switching steps of a step sequencer, changing the root or scale of a quantizer or chord generator and much more. Also you can use buttons for overlaying a single pots with multiple switchable functions.

You can attach up to 16 controllers to one DROID master. This is done with a 6 pin ribbon cable. This module gets its power from the DROID master.

Besides the P4B2 there are many other types of controllers for the DROID.

Notes: TRS Split - CV/Audio signal distributor

TRS Split is a multipurpose CV and audio signal distribution module. It has three 3.5 mm TRS (tip/ring/sleeve - stereo) jacks and six ordinary 3.5 mm mono jacks.

It contains 3 identical sections set up as following:

Upper jack carries the tip signal
Middle jack carries the stereo/dual signal
Lower jack carries the ring signal

Each section can either split a stereo signal into two mono signals or join two mono signals into one stereo signal. The module does not have any active components and does not need a power supply.

Use cases:

When you plug a stereo signal carried by a stereo (TRS) cable into the middle jack, you receive two separate mono signals by plugging in a mono (TS) cable in the upper jack to carry the left signal and a mono (TS) cable in the lower jack to carry the right signal. That way you can attack an "AUX" cable such as from your smartphone to your modular.

Or the other way around: Send two separate mono signals by plugging in a mono (TS) cable in the upper jack to carry the left signal and a mono (TS) cable in the lower jack to carry the right signal. Receive a stereo signal at the middle jack to be used with a stereo (TRS) cable.

Converting from stereo to dual mono and back allows you to alter the two sides of a stereo signal with different effects/filters.

Some tuners such as the Korg NTS-2 accept inputs to tune two oscillators combined in one 3.5 mm stereo jack. With one splitter you can easily feed two VCO signals into such a tuner.

Switching sides

Two splitters can be used to switch tip and ring (left and right): Plug in a stereo cable in the middle jack of the first section. Connect mono cables to the upper and lower jack of the first section. Then connect the upper mono cable of the first section to the lower mono jack of the second section and the lower mono cable of the first section to the upper mono jack of the second section. The signals are switched. Plug a stereo cable in the middle of the second splitter and you're good to go.

Hint: This also works for MIDI signals. If you use MIDI over minijack, there are two standards A and B - some manufacturers use A some B - thus not all connections are working. Now you can easily switch between the standards using the TRS Split.

Note: The MIDI input of the DROID X7 automatically detects A and B, so there is no switching necessary. The MIDI output of the X7 can be set to A or B with a switch on the back of the module.

Stereo multiple setup

If you have a separate multiple in your modular, you can use the TRS-SPLIT to create a 1:2 stereo multiple as follows:

Plug a stereo cable in the middle jack of section 1, patch the mono cable from the upper jack into section 1 of your multiple (e.g. a 3/3/3 multiple) and feed two of the outputs back into the upper jacks of section 2 and 3. Do the same with the mono cable coming from the lower jack of section 1 going into the second section of a 3/3/3 multiple and patch two cables back into the lower jacks of section 2 and 3 of the TRS Split. Now the middle jacks of section 2 and 3 both carry the stereo signal.

Notes: TRS Tool - Stereo/Dual CV/Audio/MIDI signal multipurpose module

TRS Tool is a multipurpose CV and audio signal distribution module for working with 3.5 mm stereo jacks (tip/ring/sleeve). These jacks are common for stereo audio but also for MIDI.

The TRS TOOL has no active components and does not need a power supply. It contains 3 different sections set up as following from top to bottom:

TRS Split
The upper jack carries the tip signal
The middle jack carries the stereo/dual signal
The Lower jack carries the ring signal

Use cases:

When you plug a stereo signal carried by a stereo (TRS) cable into the middle jack, you receive two separate mono signals by plugging in a mono (TS) cable in the upper jack to carry the left signal and a mono (TS) cable in the lower jack to carry the right signal. That way you can attack an "AUX" cable such as from your smartphone to your modular.

Or the other way around: Send two separate mono signals by plugging in a mono (TS) cable in the upper jack to carry the left signal and a mono (TS) cable in the lower jack to carry the right signal. Receive a stereo signal at the middle jack to be used with a stereo (TRS) cable.

Converting from stereo to dual mono and back allows you to alter the two sides of a stereo signal with different effects/filters.

Some tuners such as the Korg NTS-2 accept inputs to tune two oscillators combined in one 3.5 mm stereo jack. With one splitter you can easily feed two VCO signals into such a tuner.

TRS Quad Multiple

Multiply a stereo signal. Four TRS jacks to be used with stereo minijack cables.

Use cases:

You could use this to multiply the signal for headphones - listen to patches together.

Or create sends - route one (or two) stereo signals to effects and use the third one as dry signal going to the mixer.

Experimental: multiply a MIDI signal to two or three receivers: NOTE: depending on the output power of the MIDI sender and the power draw of the MIDI receivers this might or might not work. MIDI uses a current of typically 5 mA instead of voltage levels for data transmission. So when you attach too many devices to one output the current might not be enough to drive all of them. So this is strictly spoken not covered by the MIDI standard, but might work anyway.

A/B Swapper
The bottom section of the module consists of two connected TRS jacks.
Whatever signal applies to the tip in jack A will be routed to the ring in jack B.
Whatever signal applies to the ring in jack A will be routed to the tip in jack B.

Use cases:

Switch the left and right side of a stereo audio signal.

Switch between MIDI standard A and B: If you use MIDI over minijack, there's two standards A and B - some manufacturers use A some B - thus not all connections are working. Now you can easily switch between the standards using the TRS Split.

Note: The MIDI input of the DROID X7 automatically detects A and B, so there is no switching necessary. The MIDI output of the X7 can be set to A or B with a switch on the back of the module.

The Wave Transformer is a complex single oscillator with 7 audio outputs. Its method of wave shaping differs from other complex oscillators in that it is not based upon classic wave folding such as is common in West Coast synthesis, or filtration such as is common in East Coast synthesis.

This analogue, vintage-voiced, voltage-controlled oscillator features over 8 octaves of accurate pitch tracking. Its 7 simultaneous wave outputs include a unique Complex output. This strange and novel output varies between a simple waveform (triangle, unless you patch a signal into the Shape Insert jack) and a complex transformation of the harmonic structure of the original waveform. It contains a unique mixture of the fundamental frequency, odd order harmonics, even order harmonics and subharmonics. The Sub Octave panel control will determine whether the sub harmonics are derived from one octave down, two octaves down, or are muted altogether. It will vary from a simple waveform to a silhouette of your cat watching you as you react to a "present" that it left for you on the counter. No, seriously.

The module's Transform control morphs from a basic waveform through many strange iterations into a complex, gnarled mass of audio mutations at the Complex output using an asymmetrical multi differential audio transmutation circuit. You can yield countless variations on these permutations by combining this novel circuit with Hard Sync, Soft Sync, Linear FM and Exponential FM.

Additionally, you can mute the source waveform to use the circuit as a harmonic gate/VCA, rendering the Wave Transformer a voice unto itself.

If that is not enough, there is a Shape Insert that allows you to transform external oscillations and modular-level audio sources.

The Furthrrrr Generator has a main oscillator (carrier) with an extensive and fully voltage controllable wave multiplier and a modulation oscillator (modulator) that can cross-modulate the carrier. Each oscillator has hard and soft sync and also features an integrated tuner: if both LEDs are lit the VCO is at note A. Left LED is lit at note Ab and right LED at A#. Frequency potentiometers are ten-turn models and thus allow for easy tuning. Frequency range of the VCOs is 10Hz-10kHz (and much lower in modulator's LFO mode). Both VCOs feature 2 frequency CV inputs (1x with bipolar attenuator, 1x with 1V/octave), one FM input (jumper selectable between linear and exponential FM) as well as separate input for hard and soft sync. The voltage characteristic can be selected between 1V/octave and 1.2V/octave (Buchla norm).

The main oscillator (carrier) outputs the waveforms sine, saw, square and white noise. The two outputs marked with the magic eye are outputs of the "harmonic section" that generates very complex sounds by the wave multiplier and its parameters symmetry, order and Furthrrrr in the module's right-hand section. Symmetry lowers the level of even harmonics and amplifies the odd harmonics (this affects the pulse wave's width as well). Order adds saturation to the high order harmonics and resembles a low pass filter. Furthrrrr alters the level of harmonics set by the other parameters and produces very interesting, partly brute sounds with lots of harmonics by clipping and folding the wave. All three parameters can be voltage controlled. The carrier oscillator also has inputs for hard and soft sync, the sync-switch can synch directly to the modulator.

The modulation oscillator (modulator) has three wave forms with direct outputs: sine, saw and square. Using the internal modulation via the "mood section" the waveform is selected with a button; an additional staircase wave form is available here, but it can be overridden by inserting a signal into the external input socket. A switch activates the LFO mode.

The Mood section is responsible for the internal modulation of the carrier by the modulator. Switches determine the modulation destination(s) that can be activated simultaneously. These are the Furthrrrr parameter of the harmonic section, the amplitude and the frequency of the carrier oscillator. The "balanced" switch activates the ring modulation between both VCOs. intensity of modulation is controlled by the "mood index" potentiometer and the according CV input with bipolar attenuator.

Notes: The Airlectron Sensor Recorder module is equipped with a sunlight independent distance sensor to generate CV output voltages.

A distance sensor reacts to hand movements and varies the CV output voltages (bipolar/max +/- 5 V, unipolar/max 0-+10 V). The range control adjusts the detection distance (2-50 cm). The freeze function keeps the voltage when there is no continuous movement.

The recorder/looper can be used to record motion sequences for up to two minutes. This recorded data can be played back in a loop or once and restarted at the START/RESET input. LEDs indicate the status of the gate inputs and outputs.

Features:

3x controller
1x Vishay distance sensor
3x gate/trigger in- and outputs
2x CV outputs unipolar/bipolar
Power supply via Doepfer connector

Notes: The "uMM" combines a MIDI merger and two independent THRU distributors in a module that is only 4 HP wide. All sockets on the module are in MIDI TRS-B format.

At the heart of the two-input MIDI merger is a small, powerful ARM processor with plenty of buffer memory. Two MIDI streams are mixed to one output and can also be tapped via an additional second output. Two LEDs signal the operation of the merger: one LED indicates MIDI activity at the inputs, and a second LED warns of too much data at the inputs.

The second group of functions consists of two independent, separate MIDI THRU distributors. The MIDI data at the respective MIDI input can be picked up and distributed at the three THRU outputs. If required, a 1-to-5 distributor can be created from the two units by connecting an output of the left group to the input of the right group.

4x MIDI IN (TRS-B)
2x MIDI-OUT (TRS-B)
6x MIDI-THRU (TRS-B)

Notes: Advanced generative sequencer featuring mutes per channel and transposition facilities.

Akropoli is an extension and enhancement of our successful Little Melody and High Towers modules, offering the features of both of these modules as well as some of it's own unique features such as mute buttons per channel, manual transpose knob and 1V/oct transpose CV input. Akropoli operates using Frequency Central's proprietary TOOL V2 code, and can count in integers as well as multiples for even more subtle and evolving variations.

Akropoli is a generative sequencer based around clock divisions and a chromatic quantiser, used to create in-the-moment licks and riffs. It is more that the sum of it's parts.

Akropoli's internal operations can be considered as 4 clock dividers patched into a CV mixer via attenuators. The attenuators select notes over a 5 octave range, the clock dividers determine how often those notes are added to the mix. The final output of Akropoli is quantized chromatically for fast set up and continuously pleasing results. Akropoli has an onboard transposition knob, as well as a 1V/oct transposition CV input.

The 4 clock dividers are labelled A, B, C, and D. They all receive clocks from the same source, the divisions may be selected using the presets and the individual division selectors. The clock dividers can be set to count up, down, or to one of a variety of modes that move between counting up and down. For further information on Presets and Modes see the Little Melody User Guide.

Additionally, each clock divider has it's own binary output (either high or low), these 4 outputs can be used to clock/gate/trigger other stuff on other modules to great effect.

The Herzlich 4x4 Switched Passive Matrix Mixer is a fresh dose of hot old school synth flavor right into your signal chain - inspired by the Buchla and Synthi matrix mixers of yore, the Herzlich 4x4 Passive Switched Matrix Mixer will give you all the joys of an old school matrix mixer, and none of the pesky conveniences of a modern one!

Looking for a super clean, powered matrix mixer that will treat your signals with velvet gloves and behave with mind-numbingly boring predictability? Then you've taken a wrong turn, and instead of finding the pristine tedium you sought, you have uncovered a sleeping beast, an uncut diamond the size of a bell pepper and an all-red rainbow all in one. No power needed, and a super slim profile for even the shallowest skiff user.

The Switched Passive Matrix Mixer will set your heart ablaze with its glorious commitment to happy accidents and unapologetic jank. With absolutely no electronics to rein in the monster that resides in its circuitry, you will be delighted and shocked as you turn the knobs and click the switches, to find channels that bleed gently into each other, pots that alter channels other than their own, and switches that may take your desire to open and close them as suggestions rather than commands.

Notes: Dual Full Wave Rectification for Fun and Profit

Are you sick and tired of having pesky negative waveforms interfering with your signals? Do you detest seeing the back-and-forth motion of AC waveforms going backwards, then forwards? Those days are OVER with the Herzlich Labs FWR, a dual full-wave rectifier that puts an end to negative waveforms!

When you plug a signal into the FWR, you get two outputs in return, which have fully rectified the input. All negative inputs will be kindly returned to you in pristine, fully positive form. Beautiful bouncy sine waves, turned into pure "Oops! All Positive Waveshapes"-cereal, just the way you like it.

Use it anywhere where you want ONLY positive vibes, or use it with an inverter to get ONLY negative signals, if you please. Yes, you get two of these functions in just 2hp!

Dimensions: 2 HP

Notes: Two bipolar LEDs allow you to visualize your voltages as they swing between positive and negative, as well as their level of intensity, without affecting the signal you input.

Think of it as a 1D oscilloscope in just 2hp! An easy way to grasp what your patch is currently doing, without sacrificing the money or space on more fully-fledged solutions. Useful as part of a patch to keep track of your oscillations, as a troubleshooting device to quickly verify that something is doing what it should be doing, or simply as a healthy dose of blinkenlights in addition to your existing array of sparkling LED pleasures. Best of all? You get two in just 2hp - you'll have to spend some serious cash to get that kind of function-per-hp density anywhere else!

Notes: Bartender? The power of gate signals at the touch of a button, please - but make mine a narrow one!

You already know what this is: it's a gate signal generator, and it generates gate signals. That's all there is to it. You press the button, the LED indicator lights up, and you get a 5v gate signal! Brilliant!

You get three, in just 2hp! That's 1 1/2 gate signal generators per hp! That's more than [competing product] from [competing brand]! You knew you made a good decision when you decided to look at this product.

All that remains now is to open your heart, and your wallet. Buy this gate generator - this version is the latching model (stays on or off after pressing). In fact, it works really well with the Quad Gate to Trigger Converter, also from Herzlich Labs - now you can generate both gates and triggers with ease! And in such little hp!

Oh, one more thing? Your friends are going to be very envious of this, when you show it off. Gold plated nuts, gold plated front panel, tastefully matte indicator LEDs, pleasantly tactile buttons, black hardware. All the details have received the closest care and attention.

Notes: Drawing inspiration from the MMI Maxima, the MMI Helios is intended as a middle ground between the gestural control surface of the Maxima and the fingertip control of the smaller MMI.

Less density, but a much higher degree of patch control is the key point of the Helios, which complements other MMI devices very well, and can be joined with other Helios (Helii?) to form larger and creative control surfaces.

The design is greatly simplified compared to the original MMI, with only two I/O jacks - either can function as input and output, and their interaction with each other is determined by touching both plates simultaneously to form a connection, or in cooperation with other MMI devices.

Available in a "right" and "left" version - one is an exact mirror image of the other, which makes it suitable for having two units adjacent to one another.

Dimensions: 8 HP

***Please note: the "righthand" version is not included, it is shown in the picture for demonstration purposes only. ***

Notes: Beauty. Refinement. Attenuversion.

It's another Herzlich Labs release: the 2hp stereo Attenuverter. Two channels of connected attenuversion, allowing you to fully and smoothly invert any signals you plug in - turn negative to positive, turn phase to antiphase, and find all the variations in between.

With the usual pleasantly tactile sliding pot, the sAttenuverter is both performance friendly and inspiring to use. Extremely suitable for linked mono signals and stereo alike, it will feel right at home in the increasingly popular stereo setups in modular.

Dimension: 2 HP

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.

Expander module for the Tetrapad, Intellijel's multi-dimensional performance touch controller. Adds huge functionality, allowing you to sequence parameters and create complex modulation.

Supllier notes:
Tete is the long awaited and highly anticipated expander for the Tetrapad.

Some of the key features:

Three primary modes: VOLTAGES, NOTES and COMBO.

VOLTAGES mode:

Up to 16 voltage storage locations (grid) with 8 voltages stored at each location.

You have the choice to record and playback your recall of these locations in a looper style (just play freely and spend arbitrary amount of time at any location) or as a clocked sequence (SH-101 style). Additionally you can traverse the matrix using the X and Y CV inputs to get Cartesian style sequencing.

There is also variable slew that allows you to morph/glide between the values.

NOTES mode:

You can create sequences or loops in chord, scales or keyboard mode. The isomorphic keyboard grid can vary from 4 notes to 12 notes max. There are real-time performance looping, transposition and inversion capabilities via the CV inputs and dedicated loop button. In sequencer mode each step can be a tie, rest, or gate with size 25/50/75%. Basically we have created a way to very quickly and intuitively make chord sequences that are very musical and easy to manipulate. It is difficult to summarize in words but we will be sure to create some videos to demonstrate how easy and fun this is to play with. It definitely represents something unique in the landscape of Eurorack sequencers.

COMBO mode:

In this mode you can loop record your performance on any combination of the following functions:

fader, bipolar fader, drum hit, switch or LFO. Kind of like Elektron style parameter locking but all of the motions is recorded continuously instead of just in slices. Instantly turn a simple patch into a highly animated and complex beast.

With all of the above mentioned loop recording modes you can very easily overdub since the Tetrapad detects pressure/pressing. In combo mode you can erase individual channels.

All modes allow for internal or external clocking and configurable syncing.

All of the modes have special XYZ CV modulation assignments and make use of the dedicated CV outputs.

For example, in Looper mode one of the CV outputs generates a continuous ramp that represents the position in the loop. This can be used with devices like the Planar 2 in Interpolation mode to sync the recorded patterns together no matter what tempo.

Notes: An ultra-compact 10HP VC filter with bags of personality. Camber can be treated as a subtle, non-intrusive sound design tool, or something much more lively.

Camber is designed to be a fun, tactile filter with a small footprint. It's sound is neutral enough for basic filtering without a fuss, with a much more aggressive tone available using high resonance settings in three-pole mode.

Filter Core

The core of the filter is based on a state variable topology using 2164 VCAs and 1% tolerance integrating capacitors. Resonance and feedback control is provided by the fantastic circuit design originally by Neil Johnson "Voltage Controlled 3-Pole State Variable Filter" recently made available in Sound Semiconductor documentation.

Operation

Camber is switchable between low pass and high pass responses with one pole (6dB) and three pole (18dB) flavours of each. It has full CV control of both cutoff frequency and resonance amount. The input is DC-coupled allowing LFO and CV signals to be routed through the filter. The filter will also act as a simple oscillator producing a clean sinusoidal signal with the resonance control turned *almost fully clockwise, and no signal at the audio input. Dialling in the resonance so that it is just under the point of self-oscillation allows the filter to be "Pinged" by sending gate signals to the audio input. This is useful for tuned percussion sounds and FX.

Notes: Lush analogue EQ switchable between tilt and Baxandall high-shelf configurations.

Perform a variety of mixing and sound design duties ranging from subtle brightness and clarity adjustments to low-end rumble removal, boosted low-pass filtering and sweep EQ.

In the default tilt mode, turning the control knob clockwise simultaneously boosts treble and cuts bass. Turning anti-clockwise boosts bass and cuts treble. These boosts and cuts are pivoted around the mid-range. With the control knob at 12 o'clock the frequency response is neutral.

With Baxandall high-shelf mode enabled, turning the control knob clockwise past 12 o'clock introduces and gentle high-shelf EQ weighted around the upper mid-range. Turning the control knob anti-clockwise results in a wide high-shelf cut with subtle bass and mid-range adjustments.

Patching the channels in series allows for radical sound shaping and band-pass responses. Each channel provides up to +/- 8db of low and high-frequency gain control, summing into a low noise output stage. Hot input signals over 15vpp are saturated by active Zener diode clipping.

Notes: Tilt is the first in Laine's series of core modules, which will take cues from the main product line and strip back the features so both the module width and cost can be shrunk dramatically.

Comprising an 'Ambler' style tilt EQ network similar to the 'Stilts' topology, Tilt allows simultaneous cut and boost of low and high frequencies using a single control.

Tilt control circuits are known for the transparency of their cut and boost curves, coupled with the inherent emphasis gained from cutting one end of the frequency spectrum whilst boosting at the opposite end.

It sounds pretty good on all audio source material but is especially suited to tracking drums, guitar and lead, or manipulating effects sends and returns.

With the control knob at 12o'clock the sound passed is neutral. Turning the control knob clockwise will boost high and cut low frequencies pivoting from a fixed mid-range point. Turning the control anti-clockwise below 12 o clock will in turn boost low frequencies and cut the highs.

In addition to the EQ there is a soft clipping network which will begin to saturate signals over 15 volts peak to peak.

Tilt uses the same high quality OPA op amps, Alpha pots and ENIG PCBs as found in our main product line.

Notes: Saturation is a sound designer's best friend. As applying saturation to a sound can make it sound warm, rich and defined. But without any other processing the opposite can happen; making the sound harsh, destroyed and undefined. An often used technique in music production is to saturate specific parts of the spectrum, adding harmonics to enrich the sound but not lose its original quality.

Wyvern takes this technique and makes it a creative sound design tool. When deconstructed Wyvern is built out of a specific chain: Filter EQ, Saturation, VCA, Dual Filter, Dry/Wet Balance. Different combinations of these stages can be used for a variety of sound design and patch situations. And it is all in stereo, so you can apply it to your final mix and stereo signals with ease too!

The Filter EQ stage has a high-shelf, low-shelf and bell curve to boost or diminish parts of the spectrum. When the gain is set to a minimum the EQ curves turn into low-pass, high-pass and notch respectively. A Resonance control puts emphasis on a certain frequency, or it can be used to make Wyvern scream. This is then sent to a Saturation stage. The Drive control sets the amount of Saturation of one of the three

Saturation types

Soft clipping puts more emphasis on the third harmonic and compresses the sound.

Hard clipping puts emphasis on odd harmonics. Finally an Allpass distortion adds phase shifts and distortion. The Saturation stage also has a level control which can be used to decrease the gain after saturation is applied and can function as a unipolar VCA. The Saturation stage is also accompanied with a clip indicator led and a boost switch to scale input signal correctly or simply add more or less harmonics.

The Post-Saturation stage is a high-pass and low-pass combo. Allowing you to select a frequency band from the previous stages. Along with a balance control to adjust the balance between the dry and wet signal.

Whether you are looking to destroy your sound or go for subtle analogue warmth; Wyvern has got you covered. Even when not used for saturation alone. It can be a Stereo Tone Controller, EQ, Filter, VCA and Phaser, all and anything in between. Making it a very fun and powerful sound design tool!

Features

- Filter EQ with Low-shelf, High-shelf, Bell, Low-pass, High-pass and Notch curves.
- Resonance to add emphasis on a frequency or to make it scream.
- Soft clipping, Hard clipping and Allpass distortion for a variety of flavors.
- Boost switch and clip indicator led to set Saturation scale.
- Level and VCA to adjust level while Saturation amount remains the same.
- High-pass and Low-pass combo to select a part of the spectrum.
- Dry/wet control to dial in the right amount of processed signal.
- Gain with increased and adjustable center detent position.
- V/oct tracking with temperature compensation.

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: Stereo oscillator with wavemorphing, folding, and PM

"We may have just gotten the perfect Noise Engineering oscillator - in the most compact package possible." -- CDM Blog

Sinc Legio is a simple oscillator with some tricks up its proverbial sleeve. If you need some basic waveforms, Sinc has you covered - and it makes it easy to spice up those waveforms with phase modulation, wavefolding, or hard sync. Sinc pairs well with other oscillators in your system, too: hard-sync and stereo PM inputs make complex sounds easy to patch. Combine broad-ranging timbral parameters with a vintage-inspired chorus, and you're well on your way to stereo sound-design heaven in just 6 HP.

Sinc's multiple algorithms give a world of timbral possibility at the flip of a switch. Phase modulation, plucky FM, and bright and heavy modulation await. And on top of that, Noise Engineering have added a wavefolder to it. Shape and fold to your heart's content in Fold mode.

Not only is Sinc an incredible oscillator on its own, it's also part of the Legio platform. Use the included USB cable to connect to the Customer Portal and swap the firmware to any other Legio firmware, completely free, at any time. Let that sinc in!

Notes: The classic ADSR envelope with CV control for all parameters

The ADSR module offers the classic four-stage envelope (Attack, Decay, Sustain, Release) that is not only loopable (patch the end output into gate input) but also accepts CV control over each of the stages! For the time values (A, D, R) the value set by the knob can be increased to five times the duration by the corresponding CV value. For the Sustain value the knob and CV value are simply added.

Notes: The CVSHIFTER module is the AE version of the well-known analogue shift register modules that are around in the modular world since a long time. It works like this: The CV input is sampled with each trigger input signal and this CV is sent to the CV 1 output; at the same time, all CV outputs 1-4 are shifted by one.

Compared to the "classic" circuits, this module is digital based and therefore doesn't suffer from drift as some analogue ASRs and S&Hs do. The result is, that you can e.g. control the pitch of up to four oscillators which is a first step into polyphony.

The CVSHIFTER module offers three modes:

Classic: Each trigger shifts the CV outs by one position, the new CV goes to output CV 1
Cycle: Each trigger sends the CV to the next output channel, restarting at out 1; additionally a gate signal at the according output.
Random: The CVs are sent in random order to one of the four outputs, plus a gate at the according output.

Notes: The DIODEFILTER is an adaption of the well-known diode ladder filter that became most popular by Roland's TB-303 bassline. And here it is for the AE modular!
