Notes: Roucha Legio is a 12 dB /octave state-variable stereo multimode filter available on the Legio DSP+oscillator platform.

Noise Engineering received tons of requests for NE filters over the years, and Roucha Legio is their first dedicated release. The filter features lowpass, bandpass, and highpass settings and tracks frequency via the dedicated encoder and extremely accurate 1v/8va CV input. Roucha Legio's CV-controlled resonance parameter can go from clean to acidy-squelchy for bassline joy. Add CV for filter sweeps that will knock your socks off. Of course, because it's a Noise Engineering module, there's a Fold knob. Add wavefolding to the signal chain before, after, or both before and after the filter.

Noise Engineering have made it easy to carry out dramatic buildups and cuts with Roucha Legio. Just tap the encoder to bypass; tap again to turn the filter on again. Want to automate it? Send a gate into the Bypass input. The filter will remain bypassed as long as a high gate is present.

Roucha Legio is also a DSP and oscillator platform: users can change the firmware on any Legio module, 100% free, to any other firmware in the Legio series.

Notes: Alter is an effects processor for Eurorack format. There are two versions of the Alter which are visually identical except the names "Alter 1" and "Alter 2". This is Alter 1. Internally, 1 & 2 have an entirely different set of effects from the other. Each version features 7 unique and meticulously designed DSP effects.

Control

- Controls for mix, X, Y and Sift as well as clock.
- All effects have a variation of a filter which may change effect to effect.
- X and Y control various rates, feedback and time over the different effects (note that some of the images shows a prototype which says "rate" under two of the pots. The faceplate has been changed to X and Y).
- Clock control adjusts the rate which controls the DSP which can drastically change the effect. In doing so it does slightly lower the quality of the output signal but the results are fantastic. This clock is not for synchronization.
- Mix, X, Y and Sift all have CV control inputs.
- Each control level or CV input is visualized on the control panel.

Ins and outs

- Stereo inputs with separate level/gain control for right and left channels. These levels can also act as mute as it can take the signal to 0. They can also add gain to a quiet signal.
- Peak level indicator for clipping levels at the input
- Mono input is made stereo within the DSP and outputs to both left and right channels
- Stereo outputs for right and left channels

Effects

The effect is selected by the hexagonal touch pad. The effects for Alter 1 are as follows:
1 - long delay
2 - tight, notated granular delay
3 - plate reverb
4 - shimmering reverb
5 - distortion multi-filter
6 - pitch delay
7 - stutter glitch

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: 8-input, 8-output sequential/addressable switch with manual, trigger, and CV control, plus three grouping options, multiple switching directions, and randomization.

Vice Virga is an 8-input, 8-output sequential/addressable switch with a plethora of features and extensive patchability. Vice Virga can be configured as a single 8-channel switch, two 4-channel switches, or four 2-channel switches. Equal parts automated patch arranger and performance tool, Vice Virga has loads of switching control options. Whether you want to chain sequencers, swap outputs on an oscillator, remix a trigger pattern, or mix up every connection in a patch just to see what happens, Vice Virga can do it!

Notes: Polydactyl Versio is Noise Engineering's take on a multiband dynamics processor. Polydactyl Versio is equally at home on single-instrument timbral processing and on end-of-chain gloss. Taking inspiration from Noise Engineering's Librae Legio, Polydactyl Versio applies a unique and transparent algorithm across three bands for maximal dynamic impact. Add in a multiband saturation knob and noise gate, throw in a limiter, and you have a processor that gives ultimate control of color and dynamics.

Polydactyl Versio is part of the Versio family: this platform module can be transformed into a completely different effect by loading a growing number of alternate firmwares, completely free! Plus, with open-source support and documentation at LibDaisy, you can write your own firmware. Grab a Polydactyl Versio and process your signal into submission or total rebellion with three separate bands, saturation, limiting, and noise gating.

Notes: The RS-650 Echo / Reverb is a combination of the RS-310 and RS-440 which are based on the same circuit.

It offers both delay (echo) and reverb settings in one module. It is based on a bucket brigade device (BBD) with six parallel delay taps. Those six delay times have no relationship to each other and their outputs have different levels. You have to consider the reverb effect as a mixture of six different short delays what results in a dense sound. The clock frequency which scans the bucket brigade is audible and you'll have to use a low pass filter in order to eliminate or minimize it. In Reverb mode the delay time can be set between 2.5ms and 150ms and in Echo mode it spans from 75ms to 200ms.

All modules by Analogue Systems come ready to use with five years warranty mounted in the by the customer preferred rack or cabinet.

Notes: Another clever one from Knobula, this chord-based sequencer/arpeggiator adds versatile harmonic options to your creative process. Pair it with the Poly Cinematic module for best results.

Supplier's Notes:
Generate extraordinary chords without using a keyboard.

Chord Pilot introduces a whole new take on the task of chord creation and performance offering 192 chord memories, a strummer, an arpeggiator and an 8 step chord progression sequencer, all in one compact 12hp package.

Knobula have thrown away the music theory rule book and instead offer a module that encourages the curious mind to discover alternative musical pathways, whether for generative patches or for EDM riffs.

To generate a new chord, Chord Pilot uses a series of controls that alter the width and spread of 'fingers' over a virtual keyboard before conforming them into a variety of musical moods from the pure and harmonious to the terrifying and cacaphonic.

Like all Knobula products, Chord Pilot has been designed primarily with performance in mind, to inpsire by experimentation, to lose yourself in the moment, and to occassionaly generate impossibly hard to play super chords.

With the ability to store and transfer chords in sets of eight, Chord Pilot makes a great companion module for Poly Cinematic, but it is equally at home serving any poly synth with a midi input.

Discover Chord Pilot, your guide, navigator and explorer to a whole new universe of musical harmony, and beyond.

Notes: Very nice little physical modelling voice, serving up to eight notes of polyphony via stereo outputs. Plucked strings, tuned percussion, an excellent prepared piano mode and more.

Supplier notes:
Surface is a multi-timbral physical modeling voice. Its output ranges from plucked strings and marimbas, all the way to FM drums.

Each model features stereo outputs and up to eight unique voices that can be active at a time.

Notes: Tone is a quad, voltage controlled filter with low pass and band pass outputs. Its four channel architecture enables the intuitive patching of shimmering, polyphonic textures. The 24dB slope provides a warm, buttery character. Self oscillation allows each channel to double as a sine wave oscillator with v/oct tracking across four octaves. Cascade OTA topology. A perfect match for the Chord.

Notes: Killer physical modelling module collab from two of the biggest names in their respective fields of hardware and software. Generates a huge range of percussion instruments plus synths and bass tones.

Supplier's notes:
Plonk uses a technique known as physical modelling to synthesize, with great realism, the way in which sound is produced by acoustic instruments. The Plonk module is, itself, focused primarily on creating percussive sounds - both pitched and un-pitched; natural and unnatural; acoustic-sounding or totally electronic.

Plonk does this by breaking sound creation into two distinct elements - the exciter and the resonator. The exciter is a mathematical model of the device used to strike a particular surface. Plonk, because it's percussion oriented, has two types of exciters: one modelled on a mallet, and the other providing a noise source. The resonator is a virtualization of the object being struck, which vibrates, resonates and creates the body of a sound. Plonk offers several types of resonators: beam; marimba; drumhead; membrane; plate; and string.

Plonk provides numerous parameters that let you shape, mould and design both the exciter and the resonator, thus enabling you to synthesize the sound of striking or scraping almost any type of object - real or imagined. In this way, Plonk can accurately model the sounds of kicks, snares, toms, cymbals, claps, tablas, congas and all manner of traditional percussion instruments. It can also model pitched percussive instruments, like vibes, marimbas, and even bass or guitar-like tones. Of course, it additionally excels at modelling instruments that heretofore never existed.

Best of all, the sounds created by Plonk are not static - any sound you design can respond dynamically to velocity, as well as four different modulation inputs. This means the sound of Plonk can change completely from note-to-note (or strike-to-strike). Because of this, Plonk is actually a duophonic (2-voice) module, which lets the sound of one note decay naturally when a second note (possibly employing an entirely different set of modelling values) is struck. Thus, hitting a new note does not choke the sound of the previously struck note (unless you want it to, of course)!

Plonk stores up to 128 patches in its internal memory, and ships with many presets programmed by professional sound designers and composers. You may overwrite these patches if you wish, and banks of patches may be transferred via MIDI System Exclusive over Plonk's built-in mini-USB port to facilitate offline storage by programs or websites that support this capability.

Plonk was developed in cooperation with Montreal-based Applied Acoustics Systems - physical modelling pioneers, and the creators of Tassman, Lounge Lizard, String Studio, Ultra Analog, Chromaphone and numerous other plugins. It is with great pleasure that Intellijel brings the potential of this physical modelling technology to a hands-on, CV-laden device capable of the sort of dynamic control and sonic exploration that modular synthesists demand.

Notes: A multi-VCA module on steroids, the Morph 4 is designed as a modulation hub for an entire Eurorack system, capable of working in coutnless different ways. Proper versatile business.

Supplier's Notes:
Modulation is the core concept of modular synthesis: parameters changing over time, adding movement and musical interest to what would otherwise be merely static sounds. Being able to control the amplitude of signals throughout a patch is therefore essential, and one can never have too many voltage controlled amplifiers (VCAs).

Designed as a fully-featured modulation hub for Eurorack synthesisers, Morph 4 takes the basic concept of the multi-VCA module to the next level.

Four linear amplitude modulators are controlled by a master 'morph' parameter. The response of each modulator to this parameter is completely variable, both manually and under voltage control, and can be overridden if desired. Each response is triangular, with the 'position' parameter setting the maximum point along the morph axis, while 'span' determines the width of the triangle's base.

In addition to separate signal inputs and outputs, a variety of combined outputs is available as well: A+B, C+D, add (unity gain) and averaging mixes, and instantaneous minimum and maximum. Input normalisation makes it easy to send the same signal to multiple modulators, while output and modulator response LEDs provide essential visual feedback.

The combination of master control, fully flexible modulators and multiple combined outputs creates a module truly embodying the spirit of 'patch programmable' modular synthesis. Use Morph 4 as a voltage controlled mixer, dual crossfader, dual panner, interpolating scanner, interpolating distributor, quad VCA, quadraphonic controller, slope modifier, rectifier, complex waveshaper or something in between any of those- the choice is yours.

Notes: The Shaped Dual EnvVCA is a two-channel analogue envelope generator with waveshapers and a stereo linear VCA. Unlike conventional analogue envelope modules, the waveform of each envelope can be controlled with a slider or CV without changing the envelope timing. With a wide time range from an hour to 2.5kHz, and a plethora of CV inputs and attenuverters, it can be used as an LFO, audio-rate oscillator, slew limiter, waveshaper, ASR/ADSR/complex EG, independent audio/CV VCA, envelope follower, sidechain processor, and general utility module. Each channel has dedicated linear outputs plus attenuverters and offset controls for the variable waveshape outputs, making it an ideal modulation source and stereo VCA.

Notes: A typically comprehensive approach to noise sources from Befaco, featuring five different circuits plus two analogue multimode filters and plenty of CV controls for sculpting the output.

Supplier's Notes:
Noise plethora has three different noise generators:

The first two are identical and are composed of digital algorithms followed by a 12dB analog multimode filter.
Each program has two variables (Named X and Y) addressed by two manual controls and two associated control voltage INs.
Ships with an extensive (and expanding) algorithms library: textures, wave clusters, harsh noises, and glitches.

Generator C has three simultaneous outputs:

White. Flat Response Classic white noise.
Gritty. Granulous texture noise, with voltage-controlled grit quantity.
Filtered. Is the White or Gritty noise followed by a 24dB multimode VCF.

Notes: The Variable Q VCF (or VCFQ, for short) from Random Source is a skiff-friendly Eurorack adaptation of what is perhaps the most famous Serge filter. It is an effortlessly thick and colorful 12dB/oct multimode filter with ultra-smooth resonance that never ceases to amaze. Amazing tonal variety comes from combining outputs, automating resonance settings via CV, and adding grit using its adjustable-gain input.

Simple filtration is only one of the VCFQ's many uses, however. Its amazing trigger input turns rising-edge pulses into thick analog kicks and toms which roughly track notes thanks to a dedicated 1V/oct input. This module also becomes an ultra-powerful modulator in "Lo" mode, with decaying/syncable LFOs well within grasp using the trigger input, along with free-running oscillation when self-patched. When fed stepped sequences, sample and hold, or other LFOs, the VCFQ can even function as an effective slew limiter. And that's not all: for those lucky enough to own two VCFQs, dual-peak resonance and an ultra-thick 24dB/oct low-pass mode offer some of the most rewarding synth sounds in existence. In short, adding a VCFQ to one's Eurorack system is always worthwhile.

Notes: The updated Chronoblob offers versatile, creatively interesting delay. Four modes offer a choice of stereo settings or mono with patchable feedback send and return. Tape-style modulation allows for fun pitch bend effects.

Supplier's Notes:
Chronoblob2 is a digital delay module!

Just like his little brother, Chronoblob2 can sync to a clock signal. Patch one into the SYNC input and choose a multiplier or divider for rhythmic delays. Or leave SYNC unpatched for access to continuously variable delay times!

Chronoblob2 offers four different delay modes! Dual delay mode provides two separate delays with shared controls. Ping-pong mode extends this intermingling even further by placing each delay in the feedback loop of the other.

Single delay is the classic Chronoblob mode with feedback SEND and RETURN. Patch in a lowpass filter for smooth, shadowy echoes, or get weird with a wavefolder or any other effect! Cascade delay mode expands on this archetype by also placing the second delay inside the feedback loop of the main delay, creating a wild multiplying echo effect.

Chronoblob2 provides control voltage inputs for TIME, FEEDBACK, and DRY/WET, and bipolar attenuators for each so you can dial in just the right amount of control.

In Dual and Ping-pong delay modes, although both delay times are controlled by the main TIME knob, you can voltage-control each independently with the two TIME CV inputs. The right TIME CV is normalled to the left one so you can easily control both with the same signal. Additionally, the left TIME CV is normalled to five volts, allowing you to use the attenuators as offsets from the position of the main TIME knob.

Also in these 'pink' modes, the right audio input is normalled to the left input, and the right audio output is normally mixed into the left output (patching into the right jack breaks this connection).

Like the original Chronoblob, you can select the style of time modulation with the slide switch. Choose tape mode for sweeping pitchbend effects or fade mode for smoother, cleaner changes.

Chronoblob2 offers an INFINITE LOOP button and gate input to shut off the delay inputs and lock the feedback at 100%.

Specifications:
Audio: 16bit, 48kHz
Delay: 5ms to 2.73s
Power: +12V: 80mA, -12V: 15mA

Notes: Revised take on the excellent Benjolin dual oscillator and filter from Rob Hordijk, featuring the 'rungler' stepped CV generator and extensive output options.

Supplier's Notes:
Benjolin V2 - Rob Hordijk's latest revision of the classic Benjolin. The core of the Benjolin continues to be two oscillators, the rungler (stepped CV generator), and a multimode filter.

This latest revision adds:

Reworked oscillator and filter sections

All levels are adjusted to eurorack standards

Two different steps modes (8/16 and 127)

Double and single clock rate

Externally clockable

External filter input with blend control

Notes: The Mutant Hot Glue is a versatile bus mixer for analogue effects chain design. The included analogue compressor offers series or parallel compression and a sidechain input, making it particularly well suited to drum processing. The voltage controlled distortion is based on ideas borrowed from the guitar pedals responsible for a lot of yesterday's acid style techno sounds, but improved over the guitar equivalents, and made specifically for synthesizer and drum processing. The distortion can be used in its default position, normalized to the effects send, or like every other part of the module, broken out and used elsewhere in your modular system.

Features

4 Channel Mixer with Effects Send

4 input channels, each with their own level and effects send control
Channel A mixer bypass switch and dedicated output for easy sidechain compression
Channel B is dual input, but shares level/send controls (for dual output modules, like the Mutant Hihats)
Channel C+D summed output
Main mixer output normalized to compressor input

Hi-Fidelity Analogue Compressor

Soft-knee compressor based on the same family of premium audio ICs used in some 500 Series studio gear
Dedicated threshold and compression ratio controls
Gain control dials in up to +40dB of compressor make-up gain
Compressor sidechain input for creating pumping effects
LED indicator actively displays the amount of compressor gain reduction

Voltage Controlled Analogue Distortion

A classic distortion topology reborn for modular analogue synthesizers and drum processing
In/Outputs are conveniently normalized to the module's send and return jacks
Blend control lets you adjust the mix of distorted and clean input signal
Fast responding CV input allows for complex modulation patterns and even modulating with audio signals

By default, the 4 channel mixer's output conveniently feeds into the compressor's input, giving access to easy New York style parallel compression by way of the compressor blend control. The dedicated output and mixer bypass switch for channel A allow you to use it as a sidechain source for the compressor. An effects send and return allow you to create complex effects routings within your modular system. With the number of excellent DSP and other effects modules on the market today, this makes it easy to combine modules to great effect, all within the eurorack modular domain.

Redesigned by Erica Synths in close collaboration with Hexinverter. Minor alterations were made in mechanical assembly and digital controls to address Erica synths manufacturing routines and chip shortages, but the analogue signal path is 100% identical to the original version.

In September 2022 Stacy Gaudreau - the founder of Hexinverter Electronique, announced closing down the operations. Following their announcement, Erica Synths in cooperation with Hexinverter Electronique saw a way for their incredible and truly unique music instruments to keep on inspiring musicians and finding a home in countless studios to come.
The effort and innovation incorporated in Hexinverter Electronique eurorack modules are far too great to prematurely become history. Erica Synths will take over the manufacturing, sales, and support of several Hexinverter Electronique modules. While retaining all functionality of Hexinverter Electronique modules, Erica Synths redesigned the hardware of modules and will provide support for reissue modules only.

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: Eurorack and Newtonian physics meet in this clever 'movement simulator' module, capable of acting as a VCO, LFO, envelope generator, filter and more.

Supplier's Notes:
Inertia is a universal movement simulator. It generates output curves from input stimuli and the weight of its own motion-that is, its inertia.

Just as Newton described the motion of the planets and the motion of earthly bodies with a single set of laws, so too Inertia brings together several seemingly disparate musical functions with a single, elegant abstraction. Inertia can be used as:

A rich oscillator with 5+ octaves of temperature-compensated V/O and CV over skew
A quadrature sine wave oscillator
An LFO divider
A filter with controllable, skewable resonance, from a light touch to screaming glitches
An envelope generator with nuanced, natural sounding control over the minutiae of the attack and decay stages
An intuitive sine wave skew LFO
A phase locked loop
A voltage controlled exponential slew limiter
A slew limiter with controllable overshoot and settling (like a Wogglebug)
A percussive sound generator
And more uses that we haven't yet discovered

Inertia achieves all this complexity with simple controls. The exponential rate at which the output rises and falls can be set by the rise and fall controls. Inertia then follows an input signal according to these two rates, producing a first order and second order output. But things get interesting with the momentum controls. When you add some rise or fall momenta, the output signal exceeds its target in that direction before returning to its destination. With momentum, you can create ADSR-like envelopes, skewed filter resonance, etc. When momentum is all the way up, Inertia self-oscillates, acting like an LFO or VCO.

In addition to rise/fall mode, Inertia can be set to value/skew mode, in which these same parameters are controlled as overall frequency, plus the skew between rise and fall rates, and overall momentum, plus the skew between rise and fall momenta. An LED colour and position indicates which mode is being used.

Inertia is inspired by the Dual Universal Slope Generator (DUSG), invented by Serge Tcherepnin for his Serge synthesizer system. Rather than duplicate the DUSG in a new wrapper, Inertia builds on the innovative, abstract impulse at the heart of the DUSG to create something different and new. This all-analogue circuit is original both in concept and execution, but it grows in rich soil.

Notes: Fusion VCO2 is a full analogue sound source with lots of distinct features.

The core of the module is highly stable AS3340-based VCO with three simultaneously available waveforms, transistor-based suboscillator and detune function - two BBD delay lines that make frequency shifter that is mixed back to the principal oscillator in order to emulate two detuned VCOs. Tube crunch - distinct tube overdrive - is added on the top of the mix. Furthermore, Audio input mixes an external audio signal with the principal oscillator which results in crazy sonic experience. Fusion VCO2 is exactly what you need, if you wish to get really low frequencies and have a sound that sets your modular system apart from mass!

Notes: Module A-126-2 is a fully analog frequency shifter for audio signals. A frequency shifter is an audio processing unit that shifts each frequency of the incoming audio signal by the same frequency. If the shifting frequency is e.g. 200Hz an incoming audio frequency of 1000 Hz becomes 1200 Hz, 2000Hz becomes 2200 Hz, 3000 Hz becomes 3200 Hz and so on. Pay attention that this is different from pitch shifting where all frequencies are shifted proportional (e.g. 1000>1200Hz, 2000>2400Hz, 3000>3600Hz) !
The frequency range of the internal quadrature VCO is about 8 octaves (about 20Hz ... 5kHz). If required an external quadrature VCO can be used.

The module is equipped with these controls, inputs and outputs:

Frequ. 1: first manual control of the shifting frequency (factory setting: coarse, range about 20Hz - 5 kHz)

Frequ. 2: second manual control of the shifting frequency (factory setting: fine)

by means of internal jumpers the sensitivity of Frequ.1 and 2 can be swapped (i.e. Frequ.1 = fine and Frequ.2 = coarse)

the relation between coarse and fine control is about 25:1 (corresponding to about 8 octaves to 1/3 octave)

FCV In (socket) and FCV (small control without knob): control voltage input with attenuator for the external voltage control of the shifting frequency

Mix: manual control of the up/down shift panning unit, fully CCW = down shift, fully CW = up shift, in between a mixture of down and up

Mix CV In (socket) and Mix CV (small control without knob): control voltage input with attenuator for the mixing unit for external voltage control of the up/down mixing

Audio In (socket), Level (small control without knob) and Overload (LED): audio input with attenuator, typ. audio in level = 1Vpp, the level control has to be adjusted so that the overload LED just begins to light up a bit, when the LED is fully on clipping/distortion occurs, when the LED is permanently off the input level is too low and the signal-to-noise ratio increases

Audio Out (socket): audio output of the frequency shifter

Squelch (small control without knob): controls the squelch function: fully CCW (Env.) the output VCA is controlled by the envelope signal, which is derived from the audio input signal, fully CW (open) the output VCA is permanently open (no squelch function), in between the squelch intensity can be adjusted

Quadrature VCO Outputs (sockets Sin and Cos): outputs of the internal quadrature oscillator, about 12Vpp level (+6V/-6V)

Ext. Inputs Sin and Cos (sockets): required when an external quadrature VCO (e.g. A-143-9 with a wider frequency range or A-110-4 with thru zero feature or A-110-6 with different waveforms) is used instead of the internal quadrature VCO, the levels of the external VCO should be about 10Vpp (8...10Vpp are OK) and the signals have to be symmetrical around zero Volts, the sockets are normalled to the internal quadrature VCO (i.e. the sockets are equipped with switching contacts that interrupt the internal connection as soon as a plug inserted)

VCA ext. CV (socket): used when an external control voltage (e.g. from an envelope generator) should be used to control the output VCA instead of the internal squelch unit, the socket is normalled to the output of the squelch control (i.e. the socket is equipped with a switching contact that interrupts the internal squelch connection as soon as a plug inserted). From about +8V external control voltage the VCA is fully open.

Notes: ALM turn their hand to sequencing with the ASQ-1. Multiple modes allow you to sequence up to two CV/gate channels and four trigger outputs.

Supplier's Notes:
The ASQ-1 is a multi mode Eurorack sequencer. It can simultaneously sequence two CV/GATE and four trigger patterns, as well as perform synchronised quantisation of an external CV signal. Programming of all patterns is performed using familiar classic paradigms - SH101 style step-time note entry and classic drum machine pattern editing - with satisfying mechanical computer style keys.

Pattern position, step info, length and clock division settings are communicated via the keys and LEDs. Through simple key combinations, global and performance oriented features such as mutes, transposition and saving / loading patterns are available.

ASQ-1 is designed to be a simple, immediate sequencer ideally suited to quickly jamming out ideas, having happy accidents and performing live. It is intended to be a fun and hands on alternative to the many increasingly complex hardware sequencers out there.

Features
2x step time style CV/Gate sequencers. Think 'SH101' but more turbo.
4x drum machine style pattern sequencers.
1x Clock synced external hi-res CV quantiser.
Intuitive, immediate and fun performance orientated interface with great ASMR.
Internal or external clocking with optional internal division per pattern.
Independent poly rhythmical sequence lengths.
All patterns saveable and persist with state across power cycles.
USB-C port for easy drag and drop FW updates and backing up sequence data.
Skiff friendly with reverse power protection.
Made in England.

Technical Specifications:

ASQ-1 pairs well with Pamela's NEW Workout, Squid Salmple and ALM's drum voice modules.

Notes: MachineRoom PRODIGY DUAL VCO is an analogue dual oscillator based on the legendary Moog Prodigy synth schematics. MachineRoom improved Bob's design by incorporating ICs with better thermal stability, increased the range of secondary oscillator, and also added cross-modulation possibility. As usual for this limited run of full-analogue handmade modules, MachineRoom used only thru-hole components.

The module features 3 octave registers and 3 waveforms per oscillator.

OSC1 generates SAW, SQUARE, and TRIANGLE waves with 8, 16, 32 octave registers.
OSC2 generates SAW, PULSE, and TRIANGLE waves with 4, 8, 16 octave registers.

Unlike the original version, PRODIGY DUAL VCO allows switching OSC2 to the LFO mode to modulate OSC1 or other parameters (LFO range is from 0.1 Hz to 8.6 kHz). Precise pitch tracking is up to 7 octaves.

PITCH control has a range of +/- of 1.5 octaves with a central point (to have the ability to quickly return to the initial frequency with precision). The rise/fall time of the GLIDE/SLEW is up to 5 seconds

HARD SYNC switch allows syncing the phase and frequency of oscillators.
LINEAR FM input has a built-in attenuator.

OSC2 UNISON control has a range of +/- 7 semi-tones (increase/decrease relative to the Detune central point).
OSC2 V/Oct Tracking switch activates or disables the OSC2's LFO mode. When disabled, OSC2 stops v/oct tracking, and the UNISON knob becomes a control for the LFO frequency.
OSC1 - OSC2 FM switch enables OSC2 as an OSC1 modulator.

When HARD SYNC is switched ON, Pitch/Sync knob controls the phase of oscillators.

The output level of each oscillator is about 3.5V which allows passive mixing. PRODIGY DUAL VCO is analogue so should be allowed 5-7 minutes to warm up before use.

Skiff-friendly design.

Notes: Clouds, the granular synthesis module from Mutable Instruments, was discontinued in 2017. Supercell brings back Clouds in a more accessible 34 hp form factor, offering an improved user interface and several additional features:

- Each of the Blend parameters (Feedback, Panning, Mix, and Space) have dedicated knobs with their own CV inputs and inverting attenuators (attenuverters).

- The inputs and outputs now have mute switches, stereo VCAs, and separate VU meters. The knobs act as offset controls when their respective VCA inputs are patched.

- A stereo output gain control has been added, providing an additional +6 dB of gain to compensate for low output levels when using certain parameter combinations.

- The complex process of changing the sampling time and managing presets has been simplified with dedicated switches and status LEDs.

- Extensive modulation options for all parameters including direct patching of external CV, distribution of one CV to all parameters via the AUX input, or an internal smooth random CV that is normalized to any unpatched inputs when AUX is also unpatched. The attenuverters control the modulation depth in all three cases. As of firmware v1.01 the internal modulation rate can be adjusted within a range of 1 to 100 Hz.

- The inputs and outputs now include stereo VCAs and separate VU meters. The knobs act as offset controls when their respective VCA inputs are patched.

- Pitch is now controlled by two separate inputs: the V/Oct input is exponential and the Pitch input is linear. When both inputs are used, their voltages are summed.

- A manual Trig switch (for capturing individual grains) has been added, in addition to the Trig input that was present on Clouds.

All other features of the original Clouds remain intact, including access to the alternate modes. Thanks to Olivier Gillet for making the original Clouds hardware and firmware available under open-source licenses. Third-party firmware such as Parasites (by Matthias Puech) and Beat Repeat (by Julius Kammerl) will be supported in future firmware updates after the initial release of the module.

Notes: Loquelic Iteritas is a digital VCO with interpretations of three classic synthesis algorithms involving dual pitch control. It creates a huge variety of sounds parameterized by four tone and two pitch controls.

It has had glowing reviews from Surgeon and Surachai, and I am personally very excited about this module!

It has a simple interface, with 3 different synthesis algorithms allied to a number of different controls / CV inputs which have different effects, depending on which mode you choose. Simply hook up a number of modulation sources to the 4 inputs and start wiggling!

Rev.2 now features an additional sync input.

Notes: Nicely thought out four-voice sample playback module from Parisian innovators Squarp. Load up a microSD card with samples (up to 2600 kits), then trigger and process. Neat.

** Firmware update- February 2024 ***

Thanks to a major rework of the OS, this upgrade includes an overall better sound quality and an improved latency.

Moreover, the effects Freeze and Bitcrusher have been redesigned, and the parameters Start and Sample Length are now exponential to facilitate the fine-editing of your samples.

Supplier's Notes:

Rample waves system

Eurorack 4-voice sample player & audio processor

Versatile sample machine

From percussive drum-machine kits to synth samples, breakbeats to sound FX, backing tracks to hour-long audio music, Rample can play up to 4 .wav files on independent audio outputs :

These samples are stored inside the provided SD card, and organized as kits, from A00 to Z99... allowing up to 2600 banks of 4 voices, with on-the-fly loading! The SD card is preloaded with tons of samples, and we made it very easy to import your own kits.

Thanks to the DC coupled audio outputs, it's also possible to play CV waveforms.

Effects rack

Each voice has its own "rack" of effects, and all audio effects can be enabled at the same time, allowing you to manipulate your samples in real time, from a gentle lowpass to massive destruction!

pitch - a great sounding pitch engine, based on a 6-pole interpolator, which ranges from -1 octave to +1 octave.

bits - two different bitcrushing algorithms, based on sample rate and resolution reduction. It produces distortion and warms the audio signal.

filter - a low resonance filter, DJ-style, cutting off the high frequencies or the low frequencies.

freeze - sample and loop a fraction of the played waveform, creating a glitching effect.

levels - decrease the gain or drive the signal.

It's also possible to edit 'advanced parameters' like the start point, sample length, attack/decay and run mode, and create mute groups without breaking a sweat.

Finally, thanks to the 4 CV inputs, any of the effects (or advanced parameters) can be assigned to create amazing modulations!

Multi-layer sampling

One of the key feature is the ability to "multi-sample" your kits, multiplying Rample's potential. Each voice supports up to 12 samples, can be played randomly or in a controlled fashion. It's a great way to add complexity and variations, to create organic/acoustic sounding drums, or simply to increase the number of samples per kit (up to 48).

As an example, Squarp are providing a multi-layered drum kit, with 12 different recordings of a kick, 12 different recordings of a snare, etc. Sequencing them randomly leads to a more natural drum playing.

Another kind of multi-layered acoustic drum kit is also provided, where each drum is recorded with 12 levels of velocity. Controlling the layer to be played leads to intricate, convoluted drums programming.

Of course, it's very easy to create your own multi-layered kit, and you can use this method to perform multiple synth chords, sound glitches, voices, breakbeats, ...

CV/Gate and Midi interface

Rample is designed to be the perfect rhythmic companion of your eurorack system thanks to its Gate (trig samples) and CV (modulate samples) connectivity.

You can also use it as a standalone midi machine, without using the CV/Gate connectivity: the midi in port allows you to trig & control all samples parameters + effects values at the same time. Each Rample comes with a 'stereo jack to midi DIN' and 'stereo jack to jack' adapters, easing the chaining of multiple modules in order to create an 8-voice, 12-voice, 16-voice (or more) midi drum machine!

SD card preloaded with 200+ kits from artists and sound designers, covering a large range of audio samples

Notes: A duophonic percussion/drum module which offers you two individual, almost identical voices. Each of them has an oscillator with selectable waveforms as well as an attack-decay envelope which simultaneously can modulate the pitch and the VCA.

A large number of sockets is available which not only are used for modulating and triggering the drums but also emit any oscillator waveform and envelopes. That is utterly useful!

The first difference between both voices are the available waveforms: voice A offers square, triangle and sine, while voice B has noise, square and sine. For atonal noisy sounds like hi hats and anything cymbal voice B is more suitable.
The wave forms are switch selectable and simultaneosuly available at individual outputs i.e. you can process the audio signals exernally. Using the module's EG CV outputs plus two external VCAs you can re-create or alter the signal flow. Envelope signals and audio sources are available!

For controlling the frequency there's a hi/lo switch alternating between bass and treble, then a tune control and a modulation attenuator which scales either the envelope or a nexternal CV. besides individual inputs (A VCO and B VCO) there's also a common CV input VCO A+B which addresses both voices simultaneosuly. A VCO is normalized to the VC CV input A VCA, analogical for channel B.

The second difference is in the envelopes. Voice A has an attack-decay envelope generator with manually adjustable times. Voice B has a decay envelope with fixes attack time but with voltage control of decay time via EG 2 input and the CV EG2 attenuator.
The envelope generators are able to modulate not only the pitch but simultaneously also the level. For that reason there's an second attenuator which altternately detemines the intensity of an external CV (see above).

Each voice has an individual audio output, although OUT B works as a mix output when no cable is plugged to OUT A.

*essentially two things have changed in the + version:
-the output levels of the MIX outputs have been increased
-the frequency of the filter for noise can now also be controlled via CV

Notes: Really nice take on an arpeggiator module here. Four-channel design features editable arpeggio patterns, CV control and transposition. Real-time performance meets customisable melody generation.

Supplier's Notes:
Four-channel arpeggiator with customizable patterns and CV control

Opp Ned is a four-channel arpeggiator designed for creating patterns that can be modified with CV. Opp Ned ships with 12 of Noise Engineering's favourite arps, including tetrads, major, pentatonic major, minor third, and pentatonic minor, but you can edit and save custom arpeggios to twelve memory slots. Recall your custom arpeggios manually or with CV using the Ptn input. If you ever want to restore the factory arps, just head to the Noise Engineering Customer Portal.

The transpose input makes it easy to combine Opp Ned with external sequencers, too!

Arps have never been easier than with Opp Ned.

Notes: This module was developed upon the Tubaz Filter which was released in 2014 by Gotharman but is currently no longer in production. We loved the original module so much that we officially licensed it's circuit and expanded it to feature several new functionalities.

Here's a paragraph from Gotharman regarding the original design:
"I designed it with the purpose of adding crunch, edge and distortion to my eurorack system. It is not an ideal bandpass filter, that cuts off all frequencies above and below the center frequency.
Because of its high drive, there are, in most cases, some bleedthrough of the harmonics, that should have been cut off. You might consider calling it a "Band Add" filter. The main purpose of it, was to add edge, not to be a perfect bandpass filter."

While everything he mentions is still true we believe he was being modest, It's a dirty, gritty, growling and whining monster which promises you some of the most peculiar filter sounds you'll ever hear.
However do not classify it as a "weird" distortion unit just yet because besides this hairy character it can be easily tamed (using lower volume levels) and then, with some care and intention from the user, it will transforrm itself showing it's feline purrrrr and cuddle sweet and caring, or like any good mut, showing up at night all happy, wet and dirty from a full dog's day and will lay down at your feet while wiggling it's tail howling as yawning just happy to be back home.

As such, standard volume principles do not quite apply to these units, the Audio Levels will go up to x2 amplification, Drive will go up to x11 and master outs go up to x2. The combination of these will cover all diferent qualities it can present. Overall sound can be distorted pre-Tube (raising input levels), in Tube (raising drive) or post-Tube (raising Out levels).
Higher Inputs and Drive will always be gritty, lower Inputs and Drive volumes together with higher Output levels will make the overall behaviour more mellow and closer to what a typical filter would behave like.

No standard expectations should be considered when acquiring these units, all of the tubes were built in the 70's and were bought from various sources, we always kept the premise that no tube was a bad tube (unless not really workinng) so due to each specific characteristics no module will sound exactly the same, making each unit particularly unique. This uniqueness will be particularly evident on their resonance/self-oscilating timbre as well as in their own microphonic qualities.

Regarding power and current draw, the module is designed using a low power tube, so it won't starve your eurorack power supply.

Notes: Cursus Iteritas is an oscillator that works from a dynamically generated wavetable. It gives the user spectral-like controls over three different modes based on different conceptualizations of frequency: Fourier, which uses sine waves; Daubechies, using wavelets, and Walsh mode, using the Walsh transform. Cursus Iteritas parametrizes a wide variety of sounds, but because the sounds are all based on orthogonal functions, it has a musical tone structure and can produce an extremely wide variety of harmonic sounds.

Notes: From one of the most iconic names in modular synthesis, the Variable Bandwidth Filter is a unique design, combining two state-variable VCFs with extensive CV control for clean, versatile filtering.

Supplier's Notes:
The Serge Variable Bandwidth Filter (VCF2) is probably the rarest classic filter in the Serge system, offering a unique combination of 2 filters. According to the 1983 Serge catalogue, the Variable Bandwidth VCF (VCF2) "has a band-pass output which can be varied manually or with voltage control. This is a standard response synthesizer VCF, typical to filters used in many studio systems. In the VCF2, two state-variable VCF's are connected in series to produce a total of five outputs. High pass, low pass, two fixed bandwidth outputs, and one variable bandwidth output are available. The outputs are all flat-response (no resonance) so the VCF2 is suitable for processing concrete sounds without introducing resonant coloration to the timbres. Under voltage or manual control, cut-off frequency of the high and low-pass outputs are affected, as well as the center frequency of the two band-pass outputs. Both center frequency and bandwidth are independently controllable on the variable bandwidth output."

Now - for the first time, designed and licenced by Serge - the VCF2 is available as a eurorack module. A new switch has been added which determines if the CV-controls are routed to the first (left), second (right) or both filters, bringing even more sonic options than the original.

Notes: OCTOPUS is a powerhouse ART controller that takes MIDI in via the USB or DIN connector and outputs 8 ART channels with 8 velocity CV plus 8 drum triggers. Together with the ART oscillators the OCTOPUS provide unprecedented simplicity connecting the modular to your computer sequencers, hardware midi sequencers and keyboards. Each ART channel can play polyphonic notes, monophonic notes or create multi-channel polyphony using an internal voice manager. All together OCTOPUS can play more voices and notes from a single controller than ever was possible in modular. Using ART high speed control signals OCTOPUS can maintain low jitter for tight timing.

Please note, OCTOPUS is not a 1V/Oct midi to CV and should not be confused as one.

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

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

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

Notes: Sixteen Seconds Delay vintage eurorack version, inspired by the original looping delay from 1983.

The device topology is the same as first digital delays from that era, with an all-analogue signal path, pre emphasis and de-emphasis, compression and expansion, antialias and reconstruction filtering and input output buffering and mixing.

Digital processing is limited only to analogue to digital conversion, memory management and storage and digital to analogue conversion, all in glorious eight bits.

There's also an analogue triangle Low Frequency Oscillator for modulating delay time/pitch Maximum delay time has been increased to 32 seconds, there are toggle switches for slow/fast speed/pitch , freeze function and reverse playback.

On board modular inputs for CV control of sample rate, infinite/freeze, reverse, slow/fast, reverse, delay line retrigger for sync and stutter experimentation.

Slider illuminated controls are delay time coarse, delay time fine, sweep rate and depth, feedback and mix.

Proudly hand built in Uruguay, by Maneco Labs also creators for the Grone Drone machine Eurorack, Tabletop and Pedal drone generators among others.

Notes: There is almost no modular system without at least one filter-module. You can look at them as the stars within the giant Eurorack-jungle. twinVCFilter is such a star as well. A dual filter module with flexible routing and excellent audio properties. It covers a huge range of different applications without the slightest effort.

Features and Routing:

Each filter section of twinVCFilter works as low- or highpass-filter with a slope of 12 dB/octave or as bandpass-filter with 6 db/octave. Signals can be directed in three ways through the module:

- Serial: The incoming signal passes both filter sections in a row.
- Dual: The filter sections act completely separated of each other. As if they were two individual filter modules.
- Parallel: The incoming signal passes both filters at the same time.

With these routings you can i.e. generate bandpasses or notches with variable slopes and different resonance settings or doubling the filter's slope. These are the more obvious combinations but there is a lot more to discover.

The convenient link-feature allows to couple cutoff- and resonance of both filter sections for straightforward stereo use in dual mode.

Mix section:

The flexible signal-routing is supplemented by the mix-section. Here you can crossfade both filter sections manually or by control voltages. Seamless movements from low- to highpass-filter, is as easy as crossfading from half to doubled slope. Of course you can mix two completely individual signals or toggle between them by using a rectangle-LFO-modulation.

Resonance:

Resonance is a key factor in the context of sound-shaping and sound-generation using a filter. Therefore we carefully trimmed twinVCFilter's resonance to be as musically and stable as possible. You can apply subtle frequency-dependent emphasis to signals and tear them up to self-oscillation. The latter generates a solid sine-wave which is an excellent base for percussive sounds. Possible cross-modulations significantly enhance the sound-generator features. By the way: If you are missing a vibrato-LFO in a patch, twinVCFilter can do the job.

twinVCFilter offers a huge set of features to form impressive soundscapes. It can take subtle influence to signals or massively truncate frequencies. It leaves nothing to be desired. Despite, for those who need additional possibilities we especially designed the tVCF-Extension module.

Notes: Reverb. Well...kind of.

Welcome to Aurora, a spectral reverb capable of a wide palette of sounds: from lush caverns and whale songs, to alien textures you've never created before. And likely, will invoke a hunger for exploration you felt when you first touched a modular synth.

Aurora uses a phase vocoder audio engine which separates the input signal's time and pitch domains. By blurring these signals you can achieve beautiful time-stretched tails, or cybernetic metallic effects.

Since Aurora's sonic response is entirely dependent on the input signal, no two patches will sound alike, lending itself to an infinite world of surprise and discovery.

Discovery. It's why we are all here.

A portion of all Aurora proceeds will help the fight against shrinking ice caps and dwindling polar bear populations.

Notes: The next generation 12 stage, analogue multi tap Phaser, which is a development of, and replacement for, our earlier MegaPhase 12 unit. It includes all the features of the MegaPhase 12 and is also built around the circuitry of the superb sounding EH Smallstone Phaser, which was used to such great effect on synthesisers and string machines by J M Jarre on his early albums. It has the same versatile Stage and Emphasis stage switching, and the same configuration of stereo outputs, where the left channel is taken from the Stage switch, and the Right output from the Emphasis Stage Switch.

New features include independent Level Controls for Input 1 and Input 2, and a Phase "Colour" Control, which can lighten or darken the phasing effect. We have also used much lower noise internal VCA's and low noise audio op-amps along with a four layer PCB design, so that the S/N ratio is improved and the noise floor is considerably reduced compared with the previous MegaPhase 12 phaser. Like its predecessor it occupies 18HP of Eurorack space.

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.
