Notes: Updated version of WMD's exceptional performance mixer. Full stereo design with improved sound quality, revised layout and increased expandability. An even better version of what was already one of the best mixing solutions in Eurorack.

Supplier's Notes:
Enter the WMD Performance Mixer MKII - Eight years after the MKI was released, the MKII builds on all the valuable feedback received. This is a serious upgrade, with feature enhancements and engineering improvements affecting every bit of the design.

Decisions, decisions, decisions!

If you recall, WMD showed a previous version of the PM MKII a year ago. That version was very similar to the original, with a few enhancements. Primarily focused on manufacturability and overall noise floor with some great recording features. WMD moved to an 8-layer board, replaceable channel strips, developed the MIDI and bootloader, pre/post fader headers, and made it work on both AUXs simultaneously.

Noise Performance - The MKI was alright with noise, there was a little bleed too. Going to 8-layer boards meant I could put ground planes between trace layers, and spread the traces out triple the spacing of what they were on the MKI, this reduces bleed/crosstalk by a factor of about six.

Noise Performance 2 - On the Original, the Level VCA was before the Panning VCAs, which saved on parts/power, but it meant that the Panning VCAs were always connected to the mix bus, adding noise floor that couldn't be attenuated. Making all the channels stereo and putting the Pan circuit first eliminated this problem, now the noise add is controlled by the fader. This did force WMD to make every channel stereo, so the design got simpler through figuring this out.

Panning / Crossfader - The above panning/level improvement made it possible to convert the Pan control into a crossfader, buy simply routing the post pan signals through a switch to the opposing channel, summed at the Level control. This huge improvement allowed the A/&/B input switching scheme to still work on the PM MKII, a bit differently, but it's there in spirit.

Modular Design - The channel strips are all now stereo, and identical, which makes assembly much easier, and lowers the cost. It also makes replacing them easier should a mechanical part fail or get spilled into. Further, the Patchbay, Power board, and Master section are all separate parts, so if there's a failure, they can be quickly swapped without having to RMA the whole unit.

Patchbay - The MKI and rev E MKII still had jacks misaligned with channels. This was a source of frustration for d many users of the PM MKI. And I decided to just be done with it. It didn't make sense to try to put jacks over the channel, it wasted too much space on the panel... So all the jacks go left, keeping the mixer clear of cables, this let me space the knobs out a bit to take up all 3U. It's cleaner, simpler to make, and intuitive to use.

Expandability - It's super modular now, the DB25 can connect to any two headers that spits out audio, they're all the same format across PM MKII and Channels MKII. Pre, post, mixes, connect it however you want. And the connectors can't be hooked to power, meaning no more blown opamps and RMAs to the factory. They're all shrouded too so they won't get bent in shipping!

Features Overview:

Everything is stereo. Inputs, Busses, Auxes, and Cue Mix.
INPUTS: IN LEFT is normalled to IN RIGHT.
GAIN: Each channel has a Gain trim range of -12dB to +20dB, this will let you use line level devices easily.
GAIN CLIP LED: lights red 1dB before clipping the input stage.
LVL FADER: smooth intuitive curve for easily adjusting the mix level on the fly. A yellow indicator shows the level.
MUTE: Press the channel button and the channel will soft mute with a red LED indicator.

Notes: A colourful approach to mixing here, the Kemmerskan offers two stereo channels and four mono channels, processed through germanium transistors. Three band master EQ and aux sends give plenty of creative options.

Supplier's Notes:
More than just a mixer, the Kemmeskan can be used as a soundscaping module. It has an equaliser that sounds really musical and gives the user the ability to change the sound drastically. It can be used in an Eurorack context or with external devices.

***Now featuring Assimil8or Software Version 2.0! Available to download here: http://www.rossum-electro.com/products/assimil8or/

The ASSIMIL8OR is a CV/Gate-controllable sampler with eight independent channels. Each channel is not only its own voice, but also has a separate audio output and a gate/trigger and three CV inputs. Given ever get two sample inputs and main outputs. Thus, Stereo Sampling and playback is possible. Mixed operation of stereo or mono is possible and is limited only by the maximum number of eight channels or parts.

The ASSIMIL8OR works with high-quality 24-bit AD and DA converters. Internally, however, sample and bit rate for lo-fi sound can be lowered, the latter is even CV-controllable. The samples can also be otherwise manipulated in many ways. Thus, the phase of a sample via CV or a different sample can be modulated. Likewise, the loop points can be controlled and the sample can be traversed with CV control (scrubbing), whereby wavetable similar effects could be achieved. The following parameters can be addressed via the gate / trigger and CV inputs:

- Pitch
- Level
- Bit Depth
- Phase Modulation
- Pan
- Scrub
- Sample Start
- Sample Length
- Loop Start
- Loop Length
- Release Decay

Samples and presets are stored on an SD card, which is easily accessible plugged into the module front.

Notes: The Subharmonic Oscillator is one of Serge's latest inventions and also one of his most extraordinary designs. 7 accurate analogue VCOs tied at the waist- in unison, yet their frequencies can open up like a fan, creating complex clusters. Each voice generates a pulse wave. It is temperature compensated and follows exceptional 1V/Octave tracking.

In addition, each voice provides (voltage controlled) pulse width modulation or subharmonic division as well as an individual output. The precision of these voices in combination with a global Spread control and various FM inputs opens up an enormous sonic range from massive unisono sounds to dissonant, orchestra-style textures.

The ODD and EVEN outputs enable the use as a stereo oscillator.

Endlessly customisable digital 'modular system within a modular system'. Includes more than 80 modules, allowing you to create effects, synths, control devices, oscillators, filters and much more.

Supplier's Notes:
What's a Euroboro?

The ZOIA Euroburo is a digital modular system that can be placed in your modular system, a real Russian nesting doll situation. We added a headphone output and a super-slim optional case so the Euroburo can live happily on your desktop or be easily mounted in a Eurorack case. Hence the euro + buro, pronounced "bureau"...get it!?

Create unique signature effects, synthesizers, sequencers and more while using 4 freely assignable CV ins and 4 outs to interface with other CV enabled devices. The additional headphone output and powered 9v case makes the module even more desktop friendly. With over 90 modules from CV utilities to audio effects, oscillators and envelopes to MIDI, the Euroburo can do almost anything to fill the gaps in your setup.

There's no need to worry about getting bogged down with endless menus or a cluttered interface. Creating patches and performing with the ZOIA is a tactile experience. Patching, deleting or moving modules and editing values can all be done quickly using the push-button grid and a flick of the encoder. With the addition of dedicated push buttons for the CV and Audio I/O, patching on the ZOIA has never been faster.

Inspirational west coast sounds from one of the masters. Additive oscillator with eight harmonics, direct outputs and powerful CV control to scan, tilt and mix the waveforms.

Supplier's Notes:
For the first time in Eurorack, this oscillator module provides outputs for the first 8 harmonics as sine waves. Also included are triangle, saw, square waves.

A voltage controlled mixer with various methods of address allows the user to scan, tilt and mix the harmonics from both panel and external voltage control. It is built on a discrete, all analog triangle core with an old school discrete transistor exponential converter. It has inputs for linear and exponential FM, the exponential with a reversing attenuator. Of course there's a 1 volt/octave trimmed CV input as well.

Power consumption: 120mA at +12 V and 90mA at -12 V

HP : 32

Notes: Extremely versatile signal routing is the name of the game here. Eight inputs and eight outputs are connected via the matrix, allowing you to route and mix audio, CV, triggers and gates via the buttons.

Supplier's Notes:
Like four 4x4 Switch Matrix set side by side, the Discrete Isoline Summation Matrix is a true matrix mixer powerhouse, a mad dream and an science experiment gone too far all in one.

As the name implies, the unit contains eight individual inputs and outputs, all of which can be individually routed by way of the isolinear switch matrix on the front panel. Inputs are arranged in rows, while outputs are assigned to columns, making it easy and intuitive to quickly route any given input to any given output. All inputs and outputs are individually buffered, and each mechanical switch offers both tactile and visual feedback in the form of a soft, audible click as well as a connected LED turning on or off to indicate the state of the current junction.

Like it's predecessor, the 4x4 Switch Matrix, the Discrete Isoline Summation Matrix is a DC coupled summing mixer, allowing both CV and audio to be mixed interally, with virtuous or disastrous results.. Finally, the unit is compact at only 28hp, and pairs perfectly with the Qatt quad attenuator, Stum quad mute and 180- quad inverter for greater control over your inputs and outputs.

You already know what you are going to be doing with this - whether your plan is to mix an ungodly amount of CV, create an incredible amount of new trigger patterns, have a massive FX routing setup, or some manner of unspeakable matrix mixer situation on your hands, you will be armed to the teeth with the Discrete Isoline Summation Matrix.

Notes: Black edition of Hexinverter's 808-inspired drum bundle. Kick, clap, snare and hat modules recreate the iconic sounds of Roland's legendary analogue drum machine, all updated with modular features.

Supplier's Notes:
Introducing four re-issues of classic Hexinverter drum modules - the Mutant Bass Drum, Mutant Snare, Mutant Clap and Mutant Hihats! These modules are perfect for anyone with a taste for classic TR808/909 sounds, but with a greatly expanded tonal range with voltage control over parameters and, of course, optional high distortion!

Notes: Expand the sound of your modular rack with incredibly lush, ethereal reverbs. Enhance signals with gorgeous chorus, flanging, and modulated delays. Create uniquely expressive synth voices with Karplus-Strong string synthesis. StarLab is a single module that will completely transform your modular rack.

The seemingly simple idea of allowing the pre-delay signal to be fed directly to the module's output led to the development of rich sounding delay, chorus, and flanger effects, all of which can be used together with or independent of the reverb.

While experimenting with short delay times using feedback and filtering, Strymon began finding very musical and expressive Karplus-Strong string synthesis sounds, and realized that StarLab could move beyond signal processing and become a truly unique voice module as well. All this ultimately resulted in the creation of a module that is equal parts reverb, delay/ modulation, and playable instrument.

From patch creation to live performance, StarLab's powerful features are easily accessible at the turn of a knob or the touch of a button. With no menus to wade through, StarLab's interface is designed for intuitive hands-on sonic exploration, while every function and control works together to respond musically and smoothly.

From perfectly voiced room ambience to vast, immersive, nearly infinite decays, StarLab offers the pinnacle of premium reverb sounds with unparalleled depth and spaciousness. Add musical intervals to the reverb signal with Shimmer, and enhance the harmonic spectrum with Glimmer, while enjoying real-time control over the size/pitch of the reverb process.

StarLab has vastly expanded what reverb pre-delay can do by allowing you to bus the pre-delay signal to the output while making the pre-delay time a modulation target. This results in the ability to create rich choruses, sweeping flanger effects, and beautiful modulated delays, while also processing signal through the reverb.

In addition to input signal processing, StarLab is a powerful Karplus-Strong string synthesis voice module that allows freely alternating bowing and plucking as well as dynamic string damping. This results in an astoundingly expressive and lifelike instrument with a unique voice all its own, which can be enhanced and expanded by the full range of StarLab's reverb capabilities.

Notes: Based on the ADDAC501 Complex Random module, the 511 expands the concept to become an even more powerful random/stochastic voltage generator. Four channels, all capable of being used for envelopes, modulation sources, sequencers and much more.

Supplier's Notes:
This module greatly expands on the principles of the ADDAC501 Complex Random from 2013.

This is a fully fledged 4 channel voltage generator capable of all things random, with quantization, probability, distribution, interpolation, time control, clock, states and a 32 step sequencer.

The module operation relies on its screen for all parameter editing, each button accesses one single page where parameters can be changed allowing a fast and fluid workflow across all settings.

Long presses on all buttons have a secondary function allowing fast Channel selection plus Mute and Hold functions.

The combination of having 2 Encoders with Push buttons allow swift navigation and editing across all pages and their settings.

Notes: Super versatile granular filtering. Incoming sounds are granulated, then processed with eight contrasting filters. Hands-on and CV controls allow you to manipulate and modulate the output.

Supplier's Notes:
Sisyphus is built around a granular engine and a palette of eight original filters. Its granular system allows multiple grains to coexist within a single stereo audio stream, where they combine and interact with each other.

This filter is based on a comprehensive granular approach to sound: rather than a granular engine followed by a filter, it offers true integration of filtering into the grain-generation process. Each generated grain carries the filtering characteristics defined by the musician and will be combined with other grains according to evolving, configurable patterns.

These filters have been developed entirely from scratch in-house, without using typical filter libraries, so they each have their own unique color for you to explore!

Filters

Lowpass: Attenuates high frequencies above the cutoff frequency. 12 dB/oct slope.
Highpass: Attenuates low frequencies below the cutoff frequency. 12 dB/oct slope.
Bandpass: Lets through a band of frequencies around the cutoff frequency. 12 dB/oct slope.
Notch: Dips around the cutoff frequency while letting the rest of the spectrum pass through.
Peak: Boosts the band around the cutoff frequency while allowing the rest of the spectrum to pass without a drastic cut.
Comb: Creates a series of cancellations and resonances based on an internal delay and feedback.
Karplus (Karplus-Strong: Simulates the vibration of a string or looping resonance by combining a short delay, feedback, and damping.
Ladder: Inspired by Moog-style analogue filters, with four stages in cascade. Features a steep slope (24 dB/oct) and a distinctive resonance that can reach self-oscillation.

Filter Controls

Cutoff (Cutoff Frequency):Defines the filter's cutoff frequency or center frequency (depending on filter type), ranging from 10 Hz to 20 kHz.

Resonance: Emphasises frequencies near the cutoff frequency, from a slight bump up to the edge of self-oscillation.

Feedback: Re-injects part of the output back into the filter input.

Variations: Introduces an instability in the setting of the cutoff frequency, resonance, or feedback (depending on the selected filter), allowing for a more or less "organic" filter character.

Grain Controls: The incoming sound is continuously sampled and segmented into buffers. Each segment is analysed, filtered, and then extracted to become a grain. You can change the length of each grain, the interval between grains, the way grains follow one another, how they are arranged in relation to each other, and their density (number and influence).

Grain Length: Adjusts the length of the audio grains. The shorter the grains, the more the sound fragments into a "grained" granular texture; the longer the grains, the closer the result is to the original sound, but filtered and delayed. When multiple grains are played simultaneously, longer grains make echo effects more noticeable.

Grain Interval: Determines the time between the start of two successive grains (or the probability of automatic triggering).

Pattern: Grains are organized according to predefined, adjustable patterns. Several scenarios allow you to explore different ways grains can combine, from highly organized to more chaotic.

Density: Determines how many grains are played simultaneously and their intensity.

Variability: Sets the magnitude of the special effects specific to each pattern.

Transition: Defines the shape of the envelope applied to the grains as they link together.

Input and Output: Sisyphus works with two parallel channels that share the same settings. You can use it either in stereo mode or as two separate mono audio channels.

CV Inputs: Four CV inputs allow control of Sisyphus using other Eurorack modules. These inputs accept the standard Eurorack voltages (0 to 8 V).

The four basic parameters that can be controlled via CV are: Grain Length, Density, Cutoff, and Resonance.

However, you can configure the module differently using an external file on an SD card. In that case, any CV input can be assigned to any control, the input voltage range (from 1 to 8 V) can be set, LED brightness can be adjusted, and more.

Notes: Meet Stardust, a cosmic tape looper.

The foundation of Stardust is a stereo looper with all the essential controls to record and manipulate sound, while supporting click-less looping transitions, an ultra-low noise floor, and high-fidelity audio hardware. However, getting the perfect loop is only half of the equation, Stardust also focuses on the texture and vibe of your recordings. Dial in a classic tape machine style warmth with wow & flutter/tape hiss controls, or take Stardust to new horizons with DSP effects. And, much like the tape-machines it takes it's inspiration from, Stardust can splice and rearrange its loops at the twist of a knob.

With an impressive set of front panel controls, the ability to save, recall, or export recordings, load samples via an included USB flash drive, and a host of configurable settings via our web editor Narwhal, Stardust is a comprehensive looper device.

Power Consumption: +12V=201mA, -12V=13mA, +5V=0mA

Notes: Foxtrot is a quad, multimode virtual analogue filter with three different classic filter types.

Each of the four filter channels can be:

1) A ladder filter, based on the classic MOOG designs from the '60 and '70s
2) A Sallen-and-Key filter based on the Korg 35 module used in the MS-20
3) A State Variable filter as used in the Oberheim SEM

Each filter type produces Low Pass, Band Pass and High Pass responses which can be morphed between using the front panel control or CV.

In addition, any or all of the filter channels can be linked together internally producing a parallel filter bank controlled by a single cut-off control or CV. Check out some of the examples for how amazing this sounds.

The AUX CV input can be switched to allow CV control of the filter response, resonance or pan of each filter channel's dual outputs.

Finally, each filter can be overdriven to accentuate the unique sound of each filter type.

Notes: At its heart, Alpha Pro is four identical VCAs, each with overdrive and stereo outputs. However, it's also possible to link any of the VCAs together to form a voltage controlled mixer. This flexibility allows Alpha Pro to replace a bank of VCAs, sub-mixers and even your output mixer.

Each VCA has two Signal inputs and a summing mixer with individual attenuators.

There are two mix buses, allowing each VCA to act stand-alone or as part of the mix. So you can configure two separate sub-mixes, with any of the VCAs contributing to the mix, or use all channels to make an 8 input, stereo output main mix.

The VCA gain is controlled by the Initial Gain knob, and two Gain CVs - again mixed together, each with an attenuator. Having two Gain CV inputs allows for more complex modulation possibilities without needing another CV sub-mixer.

Gain response can be set to exponential or linear.

The XING switch enables zero crossing detection to prevent clicks on very fast CV inputs.

Two drive modes are available, a soft clip and a harder fuzz, with the DRIVE control increasing the gain into the overdrive circuit to increase the effect.

The VCA output is stereo, with manual and CV control of pan - again, with an attenuator.

Alpha Pro is available now as a 'founders edition' which includes the Alpha Switch as standard.

Notes: Flame Black Filterbank is an analogue moving resonance filter bank.

The module is based on the Flame Curves and combines its most important functions in a more compact format. As a result, the individual outputs for the filter channels no longer found a place on the front panel.

The filterbank includes twelve-channel and a pattern player programmable via a software editor. You can use a freeware "Curves editor software" (Win/Mac) for setup and user pattern editing. The module needs a clock to run in pattern-mode. It also features a reset input to set the sequence back to the first step. The memory in the module can save up to 99 patterns. The active pattern can be seen on the display and selected thanks to two buttons.

When the Black Filterbank is in sequencer mode, the Envelope potentiometer controls the AR envelope, the Variation knob adds random velocity and release, and the Fill potentiometer controls the level of all the channels.

In manual mode, when the sequencer is off, you can select different filter-types with the Variation potentiometer: allpass, lowpass, bandpass 1-3 and highpass. Thanks to the Fill knob it is possible to sweep through the twelve filter bands. The Envelope knob smooths the sweep by activating a second band next to the selected filter band. Thus, the change from one band to another is not so abrupt.

It is also possible to play the twelve filters via MIDI like a drum module, thanks to the supplied MIDI to minijack cable. It even reacts to velocity.

There are several CV inputs for controlling Envelope, Variation and Fill parameters as well as the pattern number.

Notes: Clock generation meets waveform manipulation in this analogue harmonic oscillator. Combine with the Tobinski sequencer and/or interpolating scanner modules for the best creative results.

Supplier's Notes:
The Harmonic Timing Generator is a versatile Eurorack module that combines advanced clock generation with harmonic waveform manipulation. Combined with the Tobinski Sequencer, the module is a great tool for rhythmic and sonic creativity in the modular system.

As a reference clock generator, the Harmonic Timing Generator produces a base frequency with analogue multipliers (x1 to x8) to generate complex timing signals. Three selectors provide manual or voltage-controlled frequency switching, offering flexibility for intricate sequencing patterns. An LFO mode enables slower clocking rates, ideal for driving sequencers or generating modulation sources.

When used with the Interpolating Scanner, the sawtooth outputs of the Harmonic Timing Generator are transformed into sine waves. This allows the module to function as a harmonic oscillator at audio rates or as a versatile modulation source in LFO mode. Its dual functionality ensures that it can adapt to a wide range of patching needs, from rhythm generation to rich harmonic exploration.

The Harmonic Timing Generator is a versatile and creative tool, offering rhythmic and harmonic possibilities that complement any modular synthesizer setup. Its integration with other Tobinski modules ensures a cohesive and expansive sonic palette.

Notes: The Flame FM Kosmos is a full-featured 4-voice polyphonic FM synthesizer with integrated multi-effects unit. With 6 operators per voice and 32 selectable FM algorithms, it offers a wide range of sounds from classic FM tones to complex modulations. Each operator has a loopable ADSR envelope for detailed sound shaping.

It also allows morphing between two sound variations (A and B) and real-time control of effects. The integrated multi-effects processor includes stereo chorus, MIDI-syncable delay and reverb. Intuitive operation is paramount, with 8 knobs and easily accessible menus for all key parameters.

The module supports both analogue CV signals and MIDI control, making it extremely versatile. With 128 preset sounds and 128 memory slots, there is plenty of room to store and recall your own sounds.

Notes: OCTOPASS is an eight voice 24db/octave low pass filter based on the classic 2044 filter. All eight filters are fully analogue with gain compensation of resonance and the lovely lush sound of classic synths. A global frequency modulation CV using a 3.5mm jack can be used to modulate all eight incoming CVs of the Polytip jack. The typical use is to patch polyphonic synthesisers with the use of only a few Polytip patch cables for its audio ins and outs and its cut-off frequency controls. To tap each filter I/O or CV using discrete modules the OCTO I/O module can be used as an expander. As there are eight filters in the module special attention has been given to power consumption efficiency.

FLAME "TAKT" rhythm sequencer.

"TAKT" is a compact 30HP Eurorack sequencer module for playing or programming trig- ger/gate/velocity rhythm sequences.

The sequencer has 8 tracks with trigger/gate outputs, 8 velocity/modulation CV outputs and full MIDI functionality. The CV track can also be used independently as a modulation track. Live sequencing in looper mode is possible in two ways: SHOTS for playing "note repeats" or quantized triggering via keys or sensors.

Four tracks can be triggered simultaneously with four external distance sensors. These sensors are just 2HP slim modules that can be rack mounted at desired locations. These are connected directly to the module with narrow and sufficiently long ribbon cables, which also supplies the sensors with the necessary operating voltage. The 4 sensors and the connection cables are included in the scope of delivery. The sensors generate trig- gers/gates and can be switched live as a set between tracks 1-4 and 5-8 (e.g. via foots- witch).

Four syncable LFOs with VCOs for amplitude adjustment are also provided. The LFOs are equipped with many interesting functions. This includes 26 different waveforms, phase, amplitude, speed and output voltage. This can be unipolar or bipolar (0..+5v or +/- 5v) and additionally attenuated by AMP (amplitude) with built-in VCA. This means that the LFO outputs can also be adapted to modules that do not have an input attenuator.

Patterns can be switched live and are each up to 4 bars long. 4 patterns plus a fill pat- tern are saved as a scene. 50 scenes can be permanently stored in the module. This means that 250 patterns are available in total.

Additional inputs and outputs for controls are available. There are 4 CV inputs to be defi- ned by the user, as well as 2 programmable analog clock outputs. On the front there are MIDI input and output as 3.5mm TRS sockets. Firmware updates can be done via MIDI- SYSEX.

Notes: Part of TipTop's polyphonic range, the Octostages is based on the envelope circuits from the legendary Oberheim OB-X. Eight fully analogue envelopes with shared ADSR controls.

Supplier's Notes:
Octostages is an eight voice fully analogue envelope generator made with the original envelopes of the 1979 OBX. Each of the eight envelopes feature a Gate in, Envelope OUT, Velocity CV in and Attack CV in control as well as an output led indicator. A master output level knob and CV using standard mono jack are provided to control or modulate all envelope output levels globally. As there are eight EGs in the module special attention has been given for power consumption efficiency.

Size: 20HP - Depth: 40mm
Power: +12V 185mA / -12V 165mA

Notes: Octogain is a eight voice polyphonic analogue audio VCA plus a eight voice mixer with master level control and odd/even (Right and Left) channels for a stereo output and clipping indicator. All eight VCA ins and outs are simultaneously available through Polytip jacks and 3.5mm jacks so the module can be used in a variety of ways both polyphonic or multi-voice monophonic. The fully analogue audio path has exponential CV control. CV inputs are 0-5V, typical audio input is 10Vp.p.

Notes: Sibilla is a DSP digital stereo oscillator that aims to translate into music the beauty and harshness of a semi-barren mountain. Its sound is sculpted by various saw and sine waves running through intricate delay networks, altered by LFOs, white noises and creating constructive and destructive interferences.

Both stereo channels are the output stages of two feedback audio loops.

Each loop is made up by a main sub sinusoidal wave oscillator and two saw and sine waves with frequencies affected by the generation of harmonics (right channel) and subharmonics (left channel). All waves have different phases whose offset is constantly affected by minor variations created by two pairs of grains randomly fluctuating within the waves amplitude spectrum and being sampled at a certain speed.

Waves then meet to each other to a common point, together with two white noise sources, creating constructive and destructive interferences constantly affected by two LFOs movements.

Interferences are then run into a resonant low pass filter and then distributed to four different delay lines from which they are fed back into the audio loops at different time intervals depending on the grain's movements.

Notes: Bartender is the centerpiece of the mixer system. Four stereo channels, with two stereo aux send and two stereo returns. Each channel can be used in a mono mode where both channels are mixed. If you want to do eight channels of mono, you can put the channels in stereo mode (I know it feels backwards) and then use the pan control to control the crossfade between each channel, and then take the mono output. There is a built in cueing system so you can monitor channels in your headphones and control the blend with the main output. You can expand a Bartender with both a Barback and/or another Bartender. When connecting two Bartenders, the main level control on the 'expander' Bartender acts as a group control.

Notes: The Futureretro Transfer is a 12hp analogue filter featuring 16 different types of fully controllable filters with CV inputs, a voltage controlled amplifier, and an input overdrive. While the included 4 types of commonly used low pass filters, and the 12 specially crafted unique filters were specifically engineered to be the perfect sonic pairing with our Trax and Transient models, the Transfer also functions perfectly with any modular setup.

3 larger control pots give immediate and easy access to cutoff, input drive, and resonance control with the three smaller attenuators/attenuverters control input from the type CV, cutoff CV, and resonance CV input jacks. A VCA (voltage controlled amplifier) jack is conveniently placed at the bottom row along with standard input and output jacks.

Notes: Versatile Sinevibes software power in Eurorack form, the Radiant offers six powerful algorithms: dub delay, pole phaser, chord wrapper, feedback shifter, distortion and re-trigger. Filter, morph between presets and add optional reverb to all algorithms.

Supplier's Notes:
The Radiant, developed in collaboration with Sinevibes, is a powerful and highly creative multi-effect processor designed to bring unique and dynamic sound-shaping capabilities to modular synthesis setups.

Multi-Effect Processor with Six Selectable Core Algorithms

Radiant offers a versatile collection of six distinct core algorithms, designed to be both familiar and experimental:

Dub Delay

Pole Phaser

Chord Wrapper

Feedback Shifter

Distortion

Re-Trigger

These algorithms contribute to a wide range of sonic possibilitiesifrom ambient soundscapes and subtle modulations to complex, evolving textures and otherworldly effects.

Morphing Between Presets

One of Radiant's standout features is its ability to morph between presets. This allows for seamless transitions between different effect states, creating evolving and dynamic sounds. The morphing feature makes it ideal for live performances, as users can shift smoothly between various sonic textures.

Three-Band Filter

Radiant includes an onboard three-band filter that lets users shape their sound by adjusting the low, mid, and high frequencies. This is particularly useful for fine-tuning the effects or isolating specific frequency ranges for more controlled sound sculpting.

Reverb and Sound Reverse

In addition to the core algorithms, Radiant provides a built-in reverb, adding space and depth to the sound. The sound reverse function allows for experimental sound manipulation by reversing the audio signal, creating eerie, backward effects that can be synced to the external clock.

Preset System and Save Function

Radiant features a straightforward preset system that allows users to save and recall different effect configurations across 3 available slots. These presets can be morphed in real-time, offering expanded creative possibilities.

User-Friendly Interface

Despite its complex capabilities, Radiant is designed with a simple and intuitive user interface. The module offers easy-to-use controls, allowing for quick adjustments and real-time tweaking of effects. This makes it accessible for both experienced modular users and those new to modular synthesis, providing a powerful yet approachable tool for creative sound design.

Notes: Tiptop bring the iconic low-pass gate to their range of Buchla reissues. The 292t offers four channels which can be mixed or treated individually, with adjustable modes for low-pass filtering, VCA or the classic low-pass gate combo.

Supplier's Notes:
The 292t is a reissue of Don Buchla's low-pass gate from the 1970s, adapted for the Eurorack modular format. The module consists of four independent low-pass gates (LPGs) and retains the natural, percussive sounds of the original, all of which can be manipulated in real time using control voltages. The 292t allows you to mix up to four sounds from their individual outputs or through a summed output, functioning as a mixdown. Each channel can operate in one of three modes: a low-pass filter with a variable cutoff, a VCA with controllable gain, or a combination of both, producing Buchla's classic low-pass gate effect.

Notes: A typically clever approach to modulation from Make Noise, the MultiMod takes a control signal and modifies it into eight related outputs, adjustable by phase and timing. Hugely versatile.

Supplier's Notes:
With MultiMod...from one control signal, we create many.

In a modular synthesiser, it is easy to create complex results via complex means - patching an elaborate network of independent control signals, for example. This can be very powerful but also cumbersome to set up, and potentially difficult to control in a meaningful way. MultiMod represents a new approach: it takes a single control signal and copies it 8 times, not unlike a simple mult, except that it allows you to modify those copies by weighted adjustment of their relative phase and speed. The result is modulation that is related to the source, but not identical at each destination.

Phase sets the spacing of the signal copies in time, weighted by channel, with each progressive channel getting more out of phase from the original signal and from each other. Spread allows for varispeeding the copies by different amounts, with each getting progressively faster or slower than the original Signal. Time determines the range of time captured at the input and therefore also the depth of modulation across copies of the input signal when Phase and Spread are manipulated. MultiMod also includes Tempo, Hold, and Reset features, and a variety of Read Shapes for temporal rearrangement of input signals.

When the input is not patched, MultiMod generates an LFO that is copied eight times and manipulated in the same ways.

MultiMod is built with the latest DSP hardware which offers eight high resolution outputs, with signal input and output ranges approaching the upper limits of the analogue eurorack modular system. All I/O is capable of a 20V range at +/-10V, greatly exceeding the typical 0-5V CV input ranges on typical digital modules.

Notes: A typically well thought-out approach to matrix mixing from ADDAC, the 814 is a stereo, expandable 6x6 design with separate control and in/out modules. Suitable for line/synth level audio or CV.

Supplier's Notes:
Introducing ADDAC's take on matrix mixers, a 6x6 stereo matrix easily expandable to larger configurations.

Matrix mixers may need some time to get used to, but they are very much self-explanatory, each knob controls the volume of a matrix point routing the respective input to the desired output. The flexibility of a matrix mixer is far superior to a standard mixer, the possibility to route any input to any single or multiple outputs allow for very complex chains, combining parallel and series processing while easily reconfigurable without any extra patching.

All Inputs Left channels are normalled to the Right Inputs.

Blank areas on the left and bottom edges of the panel allow for the user to write all the inputs and outputs sources that each channel is connected to.

Different coloured knobs for faster visual recalling: Black for A,C,E Outputs Dark Red for B,D,F Outputs Cream knobs for potential feedback diagonal: 1A, 2B, 3C, 4D, 5E, 6F.

DC coupled circuitry, can be used to mix both audio or cv signals.

Jumpers on the back of both modules allow the user to set each channel independently to Line or Synth Level, making it easier to integrate with external sources, sound processors or guitar pedals.

Internal connections

The control and input modules are connected via a large 34 wire ribbon cable, only the control module needs to be connected to the Busboard.
Extra IDC sockets are used for connecting larger configurations like 12x12 or 18x18.
Other configurations are also possible: 6x12, 12x6, 12x12, etc...
Up to 12x12 all ribbon cables are provided, for larger matrixes custom ones will be necessary, contact us directly if planning to go BIG.

Potentiometers

Although ADDAC System are using Thonk's Tall Trimmer Topper for Knobs all potentiometers used have metal shaft and are not plastic trimmer potentiometers.

Notes: Legendary Vermona drum synthesis circuits get reimagined for Eurorack. The Bass/Drum reworks the kick and 'drum' circuits from the DRM-1 for extra modular flexibility, maintaining the powerful analogue sound.

Supplier's Notes:
With BASS|DRUM, Vermona have transferred the sonic foundation of the DRM1's KICK and DRUM instrument channels to the Eurorack format. They reworked the existing circuitry in key areas to optimize it for the modular context. The result is an Eurorack sound generator that clearly reveals its origins and at the same time surpasses them many times over.

The modulation possibilities of BASS|DRUM offer enormous flexibility. Many parameters like the pitch of the oscillator, the decay time and the integrated wave shaper can be controlled by external voltages. For example, you can create rhythmically alternating long and short or low and high kicks or tonal variations by modulating the waveform.

Use the DYNAMIC input to control the amount of force your trigger source applies to the internal circuitry of BASS|DRUM. This not only changes the volume, but also many different nuances of the sound.

Bass or drum? BASS|DRUM can do both, without compromise. If you need drum sounds that follow the tuning of your music, you'll find what you're looking for here. At the same time, the module serves as a full-featured audio oscillator that can be used to create bass lines or melodies.

From deep, powerful bass drums, toms and tom-toms to high-frequency pings and percussive chirps - no problem with BASS|DRUM! In combination with other modulation sources, this spectrum can be extended infinitely. The module is also an excellent oscillator for anything other than classic analog drum sounds.

Notes: Four-part probabilistic rhythm crossfader

Confundo Funkidos is a rhythm crossfader and mute utility. Patch two pairs of rhythms to the left and right inputs, then use the CV-controllable crossfader and three Curve algorithms to fade between them and combine them in different ways. Each channel has a mute switch which can be used to bring a voice in and out of a patch at will. Tap the Burn button for some instant fills, and your percussion performances will never be the same.

New to the second version is the addition of four Accent outputs. Accent patterns are generatively created using the rhythms at the inputs, adding a new, dynamic dimension to even the simplest of trigger sequences. The Accent jacks output high or low gates, which can be used with dedicated percussion modules or as modulation sources in a patch.

The Burn functionality has also been expanded, with the addition of a potentiometer for more versatile and hands-on fill creation. Even the Mute switches have been expanded with three positions: each channel can output triggers but not receive Burn fills or output accents when set to the middle position.

If you want to liven up your percussion system with a completely unique and hands-on utility, Confundo Funkidos brings modular performance to a whole new level.

Notes: Serious versatility from AJH here. Based on the circuits from the Oberheim Matrix 12, the Matrix VCF offers a whopping 16 different fully analogue filter modes, each with two different resonance models. All bases covered.

Supplier's Notes:
Presenting the new AJHSynth Matrix VCF - this may well be the most versatile Eurorack VCF ever.

This amazing multimode filter and VCA offers sixteen different filter types, and two different resonance models on each, totalling an incredible thirty two assorted resonant filters to choose from. AJH Synth have also included manual and CV control of filter type selection, along with 16 LED's that give a clear visual indication of which filter type is currently selected.

The filter core circuitry is based on that of the rare and highly sought after Oberheim Matrix 12 synthesiser, and of course has an all analogue signal path. The Matrix 12 VCF originally offered fifteen filter types, however AJH Synth have expanded this to 16 with the addition of AP4, a full four pole all pass phaser mode.

AJH Synth have added a unique P-Vox resonance distortion and overdrive circuit that changes the character of the resonance completely, and can force all of the filter modes into self oscillation. This effectively doubles the filter variants and hugely broadens what is already a very impressive sound pallet.

Other features include an inbuilt VCA with Input and Output Level controls, a Peak level LED, CV control of resonance, and of course the legendary AJHSynth build quality.

The Matrix VCF in depth

After two years of development AJH Synth have finally released what they consider to be the most versatile Eurorack VCF & VCA ever. Like many other AJHSynth modules it uses the very best vintage analogue circuitry as the starting point for the design, and in this case, the filter was chosen from the rare and very desirable Oberheim Matrix 12 synthesiser. AJH Synth expanded this from the original fifteen filter compliment to sixteen distinct filter types by adding in a really useful four pole phaser!

So, behind the compact 14hp front panel lies sixteen distinct filter types, including all of the favourites: Low Pass filters with a choice of one, two, three or four poles, Band Pass filtering with two or four poles, High Pass filtering with one, two or three pole options, along with Notch filtering and four complex, combination filter types. Finally, a four stage phaser with two types of emphasis that can be forced into tuneful self-oscillation!

However, this is far from the end of the story. AJH Synth decided to use their design expertise to add in some crazy resonance distortion circuitry, that could be switched on from the front panel. This was inspired by the filter from the Soviet Polivoks synthesiser, but again the implementation used here is considerably changed, improved, and best of all this can be applied to all filter types! This completely changes the filter character when engaged, and it forces all of the filters into self-oscillation at higher resonance settings. Better still, the oscillation waveforms are more harmonically rich than the usual sine waves - everything from gloriously fat to screaming and angry! Best of all, this takes the number of different filters up to a massive thirty two variations!

AJH Synth put a lot of thought into the ergonomics and how to select the individual filter type. Filter type can be changed either with the front panel Mode knob, or by using a control voltage patched to the MODE CV input. The selected filter mode is displayed by the LED next to the filter in use. This is also very helpful when using a step sequencer to change filter mode as it gives a real time display of the filter chosen as you take the step CV voltage up or down, while setting up each individual step.

Lastly, AJH Synth have also included a VCA hard-wired to the output - simply patch an envelope or an LFO to the VCA input, connect a VCO to the audio input and you have a synth voice (with a choice from 32 different filters!) using only three modules!

Thirty two Eurorack VCF's and a VCA would most certainly take up a lot of rack space - AJH Synth have got all of this into 14hp and managed to have a really finger-friendly user interface, without it feeling cramped.


Sixteen distinct filter modes to choose from

Here's a list of the different filter modes that are available:
1 - Four Pole Band Pass
2 - Three Pole High Pass combined with One Pole Low Pass
3 - Three Pole All Pass combined with One Pole Low Pass
4 - Two Pole Notch combined with One Pole Low Pass
5 - Two Pole Low Pass
6 - Four Pole All Pass (Phaser)
7 - Four Pole Low Pass
8 - Two Pole Band Pass
9 - Two Pole High Pass combined with One Pole Low Pass
10 - Three Pole High Pass
11 - Three Pole All Pass
12 - Two Pole Notch
13 - One Pole Low Pass
14 - Two Pole High Pass
15 - Three Pole Low Pass
16 - One Pole High Pass

All of the above filter types can be further altered by switching in P-Vox mode, this doubles the list up to thirty two different filter variants!

P-VOX MODE

Transforming the resonant character of every filter type

This magical switch completely transforms the resonance of the filter core by overdriving it in a similar fashion to the filter from the Soviet Polivoks synthesiser, which was renowned for it's powerful, aggressive character.
In common with the Oberheim Matrix 12 VCF, some of the sixteen filter types will not normally go into self-oscillation, however when you switch on P-Vox mode all sixteen filter types can be forced into self-oscillation at higher resonance settings. But that isn't the only change, the self-oscillation waveform is not the usual sine waveform, it is a rather more interesting and harmonically rich waveform that varies according to the filter type chosen - generally Low Pass modes produce the nearest to regular sine waves, whereas other filter types can produce very much more complex waveforms as can be seen in the diagrams below. It does not require any audio input for this, it can be a stand alone oscillator. Most of the filter types will track 1V/Oct reasonably well over a three to five octave range, so it can be used as a VCO with a few interesting waveshapes!

Of course, P-Vox mode isn't just useful for self-oscillation, it adds lots of character to any audio signal as P-Vox resonance is switched in.

This magical switch completely transforms the resonance of the filter core by overdriving it in a similar fashion to the filter from the Soviet Polivoks synthesiser, which was renowned for it's powerful, aggressive character.
In common with the Oberheim Matrix 12 VCF, some of the sixteen filter types will not normally go into self-oscillation, however when you switch on P-Vox mode all sixteen filter types can be forced into self-oscillation at higher resonance settings. But that isn't the only change, the self-oscillation waveform is not the usual sine waveform, it is a rather more interesting and harmonically rich waveform that varies according to the filter type chosen - generally Low Pass modes produce the nearest to regular sine waves, whereas other filter types can produce very much more complex waveforms as can be seen in the diagrams below. It does not require any audio input for this, it can be a stand alone oscillator. Most of the filter types will track 1V/Oct reasonably well over a three to five octave range, so it can be used as a VCO with a few interesting waveshapes!

Of course, P-Vox mode isn't just useful for self-oscillation, it adds lots of character to any audio signal as P-Vox resonance is switched in.

Notes: A handy combination of two of Serge's most recent designs:

The GATE (left side) is an enhanced redesign of the classic Serge Gates which can be used as a linear or exponential VCA or ring modulator or some interesting combination of these.

The VCFX 2023 is a newly designed Serge filter that is essentially a Bandpass, but also offers a Lowpass output.

Serge NEW GATES / VCFX 2023 for eurorack:

Eurorack format (3U), 18 hp
Power consumption: 24mA @ +12V, 24mA @ -12V
(NEW) Skiff-friendly: < 25mm (1")

Notes: A powerful utility module:

The 2+2 Mixer (left side) is a combo of two DC coupled 2-channel mixers with a sum out. For audio or CV purposes.

The Dual VCA is the audiophile and distortion friedly VCA taken from the Stereo Mixer. It has a special exponential response that imitates the behavior of the early Serge VCAs and allows massive amplification and overdrive. Beware - the resulting signal can get very high amplitudes (up to 16Vpp) and allows squaring of a sine or triangle wave.

Notes: Simple but effective approach to signal routing here from Jolin Rosa. The Morpher is a four-in/four-out crossfader, scanner and switcher, allowing you to shape, route and manipulate any signal with ease.

Supplier's Notes:
ROSA is a multi-mode crossfader, scanner, and switcher that allows seamless morphing between up to four inputs and outputs. With its three operating modes (Scan, Wave, and Pass), you can easily shape and route signals to fit any patch.

A quick overview:

Scan Mode: Morph between up to four inputs with adjustable curves using the KNEE control.
Wave Mode: Independently control the four VCAs for complex dynamic changes.
Pass Mode: Route a single input (or mix multiple inputs) to up to four outputs, perfect for quadraphonic setups or parallel processing.
Infinite Analogue Potentiometer: For smooth, continuous transitions.
Global SHUT Control: CV-controlled mute for immediate silence.

Notes: ***B-STOCK: Item refurbished, repaired and in perfect working order.***


Manis Iteritas is a Eurorack 10HP voice based on the architecture of Basimilus Iteritas, but designed to be more gritty and aggressive. It accomplishes this by producing only sawtooth waves that are manipulated, modulated, and distorted through a rethought interface. Manis is suitable for leads, bass lines, drums, darkness, detuned madness, or pure mayhem.

Notes: Oscar DSF is a complex, stereo Voltage Controlled Oscillator, based on the mathematics of Discrete Summation Formulae.

The Discrete Summation Formula used in Oscar DSF produces sounds rich in harmonics (or 'partials') in a similar way to FM.

The mathematics of DSFs is more complex than FM, but the way that you, the user, get the sounds you want is usually simpler. The basic sound is controlled by just two, intuitive knobs (with CVs, of course).

Oscar DSF can sound like a traditional oscillator, and it can make the usual clangs and tings associated with FM oscillators. It can handle fat bass sounds, or evolving ambient drones.

Oscar DSF has two complete DSF based, complex oscillators, controlled by the same basic pitch CV, but with a pitch offset control which can detune one oscillator up to i1 octave.

The output of the each oscillator passes through another complex FM stage, which acts like a wave folder. Technically, it's actually an FM operator with the carrier frequency set to zero. It sounds great, whatever you call it.

The final piece of the signal chain is a simple VCA, allowing Oscar DSF to be used as a stand alone synth voice with the addition of an envelope generator, or some other source of modulation.

Notes: Alpha Duo is a stereo precision VCA with ring modulation, overdrive and distortion.

Alpha Duo's VCAs have three modes:

1) Two quadrant, for classic VCA behaviour
2) Four quadrant, where the VCA responds to both positive and negative Gain CVs. This creates a classic ring modulator.
3) In four quadrant separate (4S) mode, each of the two VCA channels is controlled by separate gain CVs, turning Alpha Duo into two independent VCA/ring modulators.

Alpha Duo also features three drive modes.

1) In Drive Mode zero the overdrive circuit is not active, giving a clean signal.
2) Drive Mode One is a tube style soft overdrive. Like a tube, the positive and negative parts of the waveform are distorted differently, producing a pleasing, warm fuzz.
3) Drive Mode Two is a harder clip - more like a transistor amplifier - for a harder edged distortion.

Alpha Duo's signal path is DC coupled, so it's great for processing CVs as well as audio.

Notes: The Octovert is a CV processor capable of scaling, inverting, and offsetting up to eight polyphonic signals. It can also be externally controlled via CV! Its most obvious applications include inverting envelopes, reversing the direction of CV, and scaling plus offsetting any CV source to precisely fine-tune the modulation sweet spot of the target module. With the added feature of external control, it takes things even further by modulating the modulation signal itself for even deeper modulation motion.

Notes: Rhythmi is a Eurorack drum sequencer that allows you to dial in your groove, and explore it by evolving the pattern and modulating the energy. It allows for rhythmic inspiration and creativity without the burden of step programming. The evolve parameter enables smooth transitions between related rhythms through the use of branches. New branches can be generated at the push of a button, loading up a whole new branch of related rhythms to explore. The Evolve parameter is the heart of Rhythmi, its inspiration, and defining feature. Allowing rhythms to shift, transform, and melt into one another.

The Clock Section provides internal or external clocking with division or multiplication. The Customize Section shapes individual drum elements through density and syncopation. The Global Section introduces macro-level control over the rhythm via the Energy, Evolve, Length and Swing parameters, dynamically shaping fills and variations. Rhythmi has a jumper cable connector on the back to pair up seamlessly with Beatsi, the drum voice it was designed alongside with.
