Synth modules

Notes: Dual 1 x 4 buffered mult (one audio or cv signal in with multiple buffered outputs).

The output of the first mult is normalled to the input of the second mult to create a 1×8 buffered mult.

Notes: Dual 1 x 3 buffered mult (one audio or cv signal in with multiple buffered outputs).

The output of the first mult is normalled to the input of the second mult to create a 1×6 buffered mult

Notes: Dual 4-way passive mult (one audio or cv signal in with multiple unbuffered outputs)

On the back of the pcb is a pair of solder points marked as "link". You can connect these (with a solder blob or small jumper wire) to turn the mult into a single 8 channel Mult instead of 2 x 4 channel.

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

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

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

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

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

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

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

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

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

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

Notes: Immense power in this multi-featured sequencer from one of our favourite brands. Four channels of 64-step sequences with advanced options including probability, quantising and randomisation.

Supplier's Notes:
The Erica Synths Black Sequencer takes classical modular sequencing to the next level by adding tons of features required for contemporary modular synthesizers.

The Black Sequencer features 4 channels with CV, gate and modulation outputs, up to 64 step sequences that can be chained into songs, independent track time divisions, multiplications and lengths. It includes a built-in quantizer, LFOs, envelope generators, parameter randomization, a MIDI in/out and many other features essential for composing and performing electronic and experimental music. Even though it provides many programmable parameters per step, it's intuitive, easy and straightforward to use, and could well become a master controller for many modular setups.

Black Sequencer firmware 1.04 is now available!

It adds output quantiser which can quantise track outputs in real time or rewrite notes in the sequence. Update also adds new track and synced LFO time divisions.

Technical specifications:

Power consumption: +145mA, -25mA
Module width: 42HP
Module depth: 25mm

Notes: Pressure Points is a controller module, an analog sequencer that is played by hand. Touching the gold plated copper wires (aka Touch Plates), you become part of the circuit, generating a gate signal (Gate OUT), a control signal proportional to the amount of pressure applied (Press OUT) and the 3 Tuned Voltages for the activated Stage.

Notes: 'Beast's Chalkboard' is dual channel stepped voltage source and adder for your eurorack modular synthesizer system. It primarily is intended as a dual octave switcher for VCO's but has many other uses including sequence transposition, FM ratio creation, buffered CV distribution and VCO calibration.

Technical Specifications:

Supply: +/-12V (Reverse voltage & polyfuse protection)
Current Draw: ~30ma
Size: 6 HP
Depth: 22mm (including power header)
Offset Error: +/- 10mV

Notes: Excellent Eurorack sequencer based on random chance and evolving patterns. Dial in a series of notes and build melodies, generate and tweak patterns in real time. Huge depth for studio production or live performance.

Supplier's Notes:
The Melodicer from Vermona is a CV/Gate sequencer with an innovative concept; the melody sequencer offers twelve faders for setting the note probability and two dice-(or random) buttons for generating melody and rhythmic structure.

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

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

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

Shift:

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

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

Sequence:

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

Notes: 2HP narrow version of the A-180 multiples module. It is a passive signal splitter suitable for audio or CVs. Two sets of four jacks are interconnected, by placing a solder bridge you can connect all eight jacks.

Notes: The Buff Mult is a buffered multiple with LED indicators to show positive and negative voltages. Using wide bandwidth opamps, it functions as a dual 1-to-3 or a single 1-to-6 mult for audio, video, or CV signals.

Notes: Really impressive sequencing module with a few clever tricks up its sleeve. Eight tracks of CV/gate with built-in effects (quantise, swing, arpeggiator, etc) for processing MIDI or CV inputs. Real-time recording, step sequencing, looping and much more.

Supplier notes:
Hermod brings together a powerful step sequencer, a CV looper, a real-time effect processor, LFO generators and a complete bi-directional MIDI-USB-CV input/output interface.

Record a performance at any time thanks to the CV inputs, the USB HOST, the USB DEVICE and the MIDI input. Create and edit your tracks with the STEP mode and its piano roll and automation view. Generate crazy patterns with the randomization tool.

Hermod is polymetric, it means that each track can have a different length, from 1 step to 64 steps. Moreover, you can zoom in to increase the resolution of the step sequencer (up to 512 steps).

Polymorphic tracks:

Thanks to Hermod architecture, a track can be a simple mono CV/GATE voice, but can be easily configured as a polyphonic track (up to 8 voices), a CV/GATE + velocity + aftertouch track, a modulation + clock track... in order to perfectly fit your Eurorack system!

Sequences and Projects:

The 8 tracks are grouped into one of Hermod's 8 sequences. Every sequence is totally independent and contains a new set of tracks to be played with, for a total of 64 tracks in a single project.

Dynamic effects:

All the fun in Hermod resides in its effect system, allowing you to transform input signals, whether it's MIDI or CV. You can stack on each track up to 8 real-time effects: Quantize, Swing, Arpeggiator, Ratchet, Random, Euclid, Glide, Harmonizer, Delay, Chance, Scale, LFO... Experiment with the effects position and parameters to generate eccentric melodies!

MIDI-USB-CV interface:

Full connectivity: control Hermod with plug-and-play midi USB devices, midi keyboards, computers or other Eurorack CV systems.

Hermod is also a great midi hub, allowing you to sequence midi synthesizers/drum machines and computer's virtual instruments. Of course, Hermod can be perfectly paired with Pyramid or other hardware and software sequencer, in order to benefit from its CV/GATE outputs.

With Hermod's rock-solid clock, this module becomes a great synchronization tool for all your setup! Thanks to its powerful CPU, even when synced/slaved, Hermod allows an ultra-low latency to make the perfect link between the digital world and the analog world.

The package includes:

- Hermod "Modular Brain" Black Edition
- 1GB micro SD card + SD adapter
- Power ribbon cable
- User guide (English)

Notes: The Buchla & Tiptop Audio 245T Sequential Voltage Source Model is a powerful and flexible voltage generator that authentically recreates the original Buchla 245, now in Eurorack format.

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

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

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

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

Notes: ***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 2hp Buff is a buffered multiple capable of splitting an input signal to multiple outputs. Due to its active architecture, inputs retain their full integrity as they are copied to multiple destinations. One input signal can be copied to six outputs, or two inputs can be copied to three outputs each. The Buff is especially great for splitting pitch or audio signals where signal integrity is critical. Keep your signals in shape with Buff.

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

***

Parisian sequencer specialists Squarp turn up the goods once again with the updated Hermod+ module. Huge sequencing power for both MIDI and CV, with a range of monophonic and polyphonic features to get the most out of your sound sources.

Supplier's Notes:

Hermod+ adds so much to your system.

Based on the established Hermod workflow and keeping the same form factor, Hermod+ offers a lot of new features, and a refined, more playful interface with extended connectivity.

Record CV/Gate, MIDI notes and modulations on 16 polyphonic tracks. Compose melodic variations across 16 patterns per track, and take advantage of the advanced step sequencer and the new effects to gain efficiency and creativity in studio and on stage.

8 CV/Gate and 8 MIDI tracks

Hermod+ offers 8 CV/Gate tracks (that can also output midi) and adds 8 dedicated MIDI tracks for your extra gear.

CV inputs

Record, edit and loop analogue modulations or CV/Gate using the 4 CV inputs, and use them to synchronize Hermod+ to an incoming analogue clock.

Record live

With an improved resolution of 96ppqn, record and playback your CV/Gate or MIDI performance seamlessly without any noticeable note shifting, for up to 16 bars per pattern.

Polyphonic step composer

The revisited piano-roll now allows intuitive polyphonic editing. Edit or program chords, melodies and rhythms using the 16 built-in pads for a quick and playful composition process.

Automation

Program or record automated modulations (CV and/or MIDI) for each track, in addition to midi aftertouch, pitchbend and sustain voices.

Dynamic effects

Add up to 8 real-time CV/MIDI effects per track. All effects are non-destructive, so they can be edited at any given time to add some variations to a performance.

Advanced ModMatrix

Use the modulation matrix to link incoming CV or CC messages to effect parameters. Each modulations can be attenuverted and offsetted.

Playable song mode

Build your song structures using up to 16 sequences per project. Play them into a predefined order or launch them manually for improvised performances.

Synchronized project swap

Boosted connectivity.

The missing link between your eurorack system and the rest of your studio.

Editing made simple.

Fluid workflow with a redesigned Step mode

Step mode is where you can edit notes, modulations and gate events. Hermod+ offers quick ways to write melodies and rhythms. Zoom in and out to visualize and edit portions of your track precisely and break free from rigid grid sequencing.

The re-designed piano roll editor makes the vertical and horizontal scrolling easier and faster, while the new "row edit" feature allows for quick chords and drum patterns programming.

Create modulation curves by programming them directly on Hermod+ or by recording incoming signals, and send those curves via CV or MIDI to other parts of your system.

Versatile interface.

Polymorphic layouts for perfect integration

Hermod+ can adapt its voice layout to any patching scenario. Depending on your needs, any track can become a modulation output, a monophonic CV/Gate track, a polyphonic MIDI track...

For a track of CV/Gate note + velocity + aftertouch, or for a polyphonic CV/Gate track, simply group voices using the desired layout.

Take advantage of the 8 dedicated MIDI tracks, that can record and be programmed independently from the 8 CV/Gate tracks. Up to 8 real-time effects per track with creative parameters and generative features. Hermod+ is the canvas, the paint and the brush of your setup.

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

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

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

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

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

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

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

The drum sections features a X0X-style sequencer.

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

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

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

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

MetaModule Plugins

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

Mapping Knobs and Jacks

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

Expanders

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

Under the Hood

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

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

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

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

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

Notes: A whole lot of module for the money. Eight-track trigger sequencing with built-in drum synth, sample player and MIDI. Amazing value for studio use or live performance.

Supplier's Notes:
Trigger sequencer with audio and midi

TUKRA is an 8 track eurorack trigger sequencer with drum synth, sample player and midi.

Notes: Switched mults come to Intellijel's space-saving 1U format, offering six jacks and two busses, routing signals between the two or muting them using three-position switches.

Supplier's Notes:
The Mult 1U takes one audio or CV signal input, and (mult)iplies to up to four outputs. Because the Mult is passive, it requires no power to operate. Multiply anything by four, twice.

A signal multiplier accepts an input signal and routes it to multiple outputs simultaneously. For example, you might want a sequencer's GATE to trigger two different envelopes - one to control volume and one to control filter frequency. In order to accomplish this, you need a signal multiplier.

In addition, each Switched Mult 1U features a pair of 3-pin Link connectors on the rear panel. These let you connect other 3-pin Link devices, such as an XY I/O 1U module, or even additional Switched Mult 1U modules (handy for distributing mults across the width of your case).

Notes: Ornament & Crime for 1U Intellijel format

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

The apps currently available in Ornament & Crime:

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

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

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

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

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

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

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

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

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

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

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

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

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

Notes: Performance-focussed four-channel attenuverter and offset module, with built-in voltage generator for 0-5v or i5v voltages. Simple but effective.

Supplier's Notes:
Lapsus Os is a four channel attenuator/attenuverter and offset. Designed with performance in mind, each channel can be set to either attenuate or attenuate/invert an incoming signal, adjust offset of an incoming signal, or with nothing patched to its input, generate a 0-5v or i5v offset. Switches on the back of the module invert the fader behavior, allowing for the module to be mounted in either direction, for further customization and ease of use.

Etymology
Lapsus -- from latin lapsus : 'sliding' Os -- from latin os 'bones'
"Translation: Dancing Corpse"

Interface

Faders 1-4: The main controls of LO. The LEDs in the faders show the CV that is being passed through. When in attenuverter mode, the LED will be off at 0, allowing each fader to easily be set near 0.

Offset inputs 1-4 (+): Sending a signal to these inputs adds an offset to the input, controlled by the fader and the mode switch.

Outputs: Each channel has a pair of identical outputs. If nothing is sent to either input of a channel, an offset will be generated and output here, useful for controlling parameters on other modules with a single fader.

Uni/Bi Switches 1-4: In the Unipolar position (left), the corresponding channel attenuates the input signal. In the Bipolar position (right), the upper half of the corresponding channel fader attenuates the input signal, the lower half of the fader inverts and attenuates the signal.

Attenuating/attenuverting inputs 1-4 (x): Sending a signal to these inputs attenuates/attenuverts the signal, depending on the position of the channel fader and switch.

Rear-board switches: Below, in red. Inverts the corresponding channel, allowing for creative mounting in either direction. Note that each channel must be switched independently to fully reverse the functionality.

Patch Tutorial

Patch 1: Set a channel switch to the left position and patch the outputs to CV inputs on another module (for instance, Loquelic Iteritas). The fader becomes an easy-to-use controller for those parameters. Patch the rest of the LO channels to other parameters in your system to create an expressive and intuitive interface.

Patch 2: Patch a CV signal (such as an LFO) into the attenuverting input of a channel. Set the channel switch to the right position, and patch the output to a bipolar CV input in your system. Tweak the fader to attenuvert and dial in the perfect amount of modulation on the fly.

Patch 3: In a case with four voices route each LO channel to the decay control for each voice. Use for centralized control over voicing.

Notes: Introducing a four independently buffered input mixer and a buffered output signal splitter, in one module!

Erica Synths Black Mixer/Splitter V2 is an advanced replacement for stackable patchcables.

Everyone who knows a bit more about electronics will point out that stackable patchcables are not a really wise choice for such sensitive things as musical instruments because they mechanically connect electrical signals that at best can cause undesired modulations or even damage the modules.

Erica Black series are high-end modules with unique functionality. Only the highest quality components are used and all inputs and outputs are protected against undesired overvoltage. When designing the Black Series, design and usability were prioritised first. Big knobs are assigned to functions that make difference in sound. Together the Erica Black series are a range of modules that make an entire synthesizer.

Technical specifications:

Input signal level: -10V - +10V
Power consumption: +25mA, -25mA
Module width: 4HP
Module depth: 25mm

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

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

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

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

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

Notes: Mult 1U Intellijel Format

This is a buffered/active mult with LED indicator. You get two channels of 1 to 3 multiples within a 2HP module. The output of channel 1 is normalled to channel 2 so it can also be treated as a 1 to 6 multiple as well.

Active vs Passive mults:

With a passive mult you are effectively just plugging multiple things into the same jacks. This will often cause some voltage drop in each of the signals. With an active (or buffered) mult you will not get any voltage drop from the original signal.

Comes with a black and gold panel, power cable and one year warranty.

Usage note:

The red stripe of the power ribbon cable goes towards the top of this module.

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

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

Notes: The Circadian Rhythms is moving modular synthesizer technology another step forward by gluing all the pieces of a system together. Each module or voice can now be programmed to play straight from an intelligent, eight-channel, 512-step master trigger sequencer made for composers looking to make music on the modular. Building on the sequencing concept of step programing multi-channel patterns of musical phrases can be repeated, looped, chained, muted and manipulated on the fly in real-time, and most importantly, all of this is done through a simple, clearly labeled interface. Using an array of multicolor illuminated buttons and innovative grid views provides a highly functional live performance sequencer with a beautiful glowing appearance of the programmed music that will look amazing on stage for both performer and crowd. As a master controller, the heart of the modular synthesizer, Circadian Rhythms generates high precision clock and reset signals for all the other sequencers and devices in the system to align with and can also act as a high precision bridge for DAW synchronization.

Views - Unlike most hardware sequencers that have a single static display of a timeline, Circadian Rhythms offers four different horizontal views of the timeline and two unique vertical views that scale from macro to micro. Switch between viewing 64 steps at once or all 8 channels side by side instantly. Stretch gates over multiple patterns to drive envelopes or use Zoom view to move a single hit back a few milliseconds in time to get the right feel all from the same interface.

LED Grid Built for Quick Access - Built around 72 buttons set as a multi-color illuminated 8x9 array, Circadian Rhythms displays both note data and settings in a clear and precise manner. It takes only one click to switch to vertical view and the grid turns into a set of programming and realtime playing functions like Mutes, Loops, Swing, Fills, Copy and Pate, Grouping, Randomizing, Manual trigger entry drum machine style and many many more. Activate any of those functions with only a button press or two.

Clock - Inside the CR ticks an extremely precise clock with jitter and latency measured in mere microseconds for the ultimate feel of groove. The four modes of clock sync make interfacing with other modules, hardware or software simple. Whether driving a large Eurorack system or synced to a DAW, the groove always remains tight.

SyncBus Technology - The Tiptop Audio designed SyncBus enables the CR to connect to any number of other SyncBus devices with the highest possible level of synchronization. A SyncBus master directly injects its core clock and running status into every connected unit so they work seamlessly as one device. Hook up two CRs to make a 16 channel device or add a Trigger Riot (or three) to the mix for further experimentation. Plus, the connection is done behind the panel so no need to patch anything together.

Under The Hood - When state of the art chip technology, musically driven firmware, and professionally engineered hardware design all come together in one electronic device, the result is a music sequencer with unparalleled specifications. Starting with a powerful, precise sequencing engine that has superb feel for the groove, add internal functions that automatically balance performance and smooth user interface operation, and finish with outstanding low power consumption placing minimal stress on power supplies even at maximum output, Circadian Rhythms has a design focused on the requirements of the most dedicated musicians and composers. Long time pros will immediately feel a machine made for their needs, while the newcomers can instantly dive into next level programming and performance.

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

Notes: A 22hp version of Mutable Instruments Elements. It is functionally equivalent and therefore runs all firmware options and having identical sound characteristics. This version is great compromise between the tight spacing of Atom and full size original, which is a bit large.

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: Tesseract's step sequencer is designed for hands-on playability, configured as a 16-step or dual 8-step design. Unique features include a 'drunk' mode to add variety to your sequences.

Supplier notes:
Step Fader mkII is a 'hands on' eurorack dual sequencer, featuring two 8 step lines or one with 16 steps, plus quantizer, slew limiter, internal clock generator, CV inputs to control any parameter and more...

Each sequencer has independent settings for the play mode, start point, size (length), clock divider (or step repeat), transposition and duty cycle.
There are 16 presets to store & recall all the above settings plus CV input assignment, scale, tempo, step repeat and clock out ones.
The 2 channels of the quantizer can be used for processing external signals, same for the slew limiters.
The 16 illuminated buttons can be used to set several parameters, even to play the sequencer as a keyboard.

There are 3 MAIN SETUPS:
DUAL (2 totally independent 8 step sequencers)
PARALLEL (one sequencer with 2 rows of CV and 8 steps)
SINGLE (one sequencer with 16 steps)

There are also these PLAY MODES:
Normal
Reverse
Pendulum
Drunk
Random

Each sequencer features:
Clock input (clock input 1 is normalised to clock input 2)
Clock output
Reset input
Gate/Trigger output
Slew limiter output (unquantized)
V/OCT output (quantized)

Additionally, there are 2 summing outputs:
Gate/Trigger 1+2 (OR output of both G/T)
CV 1+2 (sum of both slew limiters)

Features 2 CV inputs with offset pots. Assignable parameters are mode, start, size, clock divider, key (the position of the sequencer is controlled by CV), transposition and duty cycle.

Dimensions: 26 HP

Current Draw:
85 mA +12V
36 mA -12V

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

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

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

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

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

Notes: For Intellijel's 1U rack format, Mosaic serve up a handy quantiser with a clever built-in arpeggiator, meaning you can generate melodic sequences from within the module.

Supplier's Notes:
Craft melodic sequences out of random voltage, LFOs, and more with the Mosaic Quantizer. Don't have a voltage source? Enter Arpeggiator mode to create a sequence from your current scale or note pattern, and modify it on the fly using the chromatic note interface. Pull musicality out of the unknown with Quantizer!

Notes: Erica Synths Black Mixer is compact, high quality audio mixer with bonus features - mute switch on each input and three buffered outputs. This allows you to add audio signals to your mix instantly and in exactly right level, plus you can send signals to several post-mixer devices simultaneously, for example, split the output signal to LP and HP VCFs and create advanced bandpass and notch filters.

Technical specifications:
Max input level: -10V - +10V
Mixer gain: 1
Power consumption : +8mA, -8mA
Module width: 6HP

Notes: mBrane is a 4 channel midi to CV interface based on opensource Yarns. The device includes a 1.5m 3.5mm TRS to Midi male cable (Type B). This is the brand new Rev1.1 of the device which now features PSImidi which allows ANY type of TRS midi cable to be used on the input. Type A or B, male or female, all will work.

Running firmware 1.5
Multichannel MIDI to CV/Gate conversion

Yarns is a MIDI interface providing up to 4 channels of very accurate CV/Gate conversion, which can be assigned to up to 4 voices.

In single voice mode, note, velocity, modulation and aftertouch (or other CC) CV are produced, along with a gate, a trigger, and a clock/reset output.

In two voices mode, two channels of note, modulation or aftertouch CV are produced, along with two gates, and clock/reset outputs.

Finally, in four voices mode, four pairs of CV/Gate outputs are provided.

Each voice has a built-in digital LFO to interpret modulation wheel messages as a vibrato; can respond to pitch-bend messages; or can be smoothed with a glide/portamento control - no need for a dedicated module and patches to get the right response from a MIDI keyboard!

Monophonic and polyphonic

The 2 and 4-voice modes are available both in a "polyphonic" and "multitimbral" flavour. The former receives chords from one single MIDI channel and dispatches them to the voices; while the later provides independent monophonic parts - which can be addressed to different MIDI channels, keyboard ranges, or even velocity levels.

Various note priority modes (low, high, last) and polyphonic allocation schemes (voice-stealing, random, cyclic) allows you to fine-tune the CV/Gate conversion to your playing style.

With sequencing and note transformation...

Each part can generate sequences either through an arpeggiator/euclidean sequencer combo; or with a SH-101 style sequencer with step-by-step recording, storing up to 64 notes. The module can sync to an external MIDI clock, and generate a clock/reset output at any subdivisions of the MIDI clock.

...and even more advanced features.

Other unique features include support for microtunings (either through standard MIDI messages or from a selection of historical tunings or indian ragas), just intonation, and an audio output mode which can transform one, two, or four of the CV outputs into simple digital oscillators.

Notes: The Circadian Rhythms, is a professional performance gate sequencer in Eurorack format. Sitting at the centre of your system the Circadian provides triggers and gates to all your drum modules and percussive sounds as well as clocking your other sequencers with exceptional timing accuracy. Each channel voice can be programmed directly from the intelligent, eight-channel, 512-step master gate sequencer designed for composers looking to make music on the modular and perform live. Building up from basic step programming, multi-channel patterns of musical phrases can be repeated, looped, chained, muted, and manipulated in real-time, and, most importantly, all through a simple, clearly labelled menu-free interface.

Notes: The Z8000 Matrix Sequencer is a modulation source like no other: The 16 knobs of the Z8000 are accessed by ten sequencers with their own clock, direction and reset inputs. The ten sequencers are as follows:

Four 4 step CV sequencers on the horizontal.
Four 4 step CV sequencers on the vertical.
One 16 step CV sequencer on the horizontal.
One 16 step CV sequencer on the vertical.

The Z8000 can simultaneously modulate up to 10 CV parameters poly-rhythmically, with unprecedented motion complexity. One knob affects all 10 CV outputs! Imagine modifying 10 parameters from one knob. With its 30 gate and clock inputs and 10 CV outputs one can only imagine the possibilities, and all clock inputs can even be driven at audio rates! The Z8000 pairs well with the Trigger Riot and Circadian Rhythms and using it with the QuantiZer extends its capabilities as a high-precision 1V/Oct note sequencer.

Introduced in 2017, a new version of the Z8000 maintains the original circuitry but adds output range adjustment switches on the back and Tiptop's new colored look, which helps highlight the sections, on the front.

New patterns are regularly added to JAZZY, based on customer requests.

New "polystep"

Input Clock is added to the two existing clocks "poly" and "matrix".

It acts as a clock divider within the limits of time division possibilities (for example, the Gaussian function will always act progressively based on an average clock, as with the "poly" clock). Thus, it falls between "poly", which produces an average of the received beats (and for example, will not account for small variations like external swing), and "matrix", which strictly applies the received beats identically to all tracks.

"Polystep" will strictly use the beats from track 1 and adapt the timing of the other tracks according to their parameters.

The "polystep" and "matrix" clocks are only useful if you want to control Skippy with an external clock. Leave it on "poly" for internal use or to use Skippy's clock as the Master for your system (in fact, Skippy performs best in the GAUSS and POLYR functions with this clock selected).

New TILES

Kaona have added the following divisions: 2/1, 3/1, 3/2, 4/3.

New ROLL Function

Beats can now be divided by two (2 "gates" instead of one) or by three (3 "gates" instead of one).

It is possible to choose a "roll" randomly: "1/??" and "2/??" add respectively 1 or 2 extra beats, randomly. You can also choose to add these "rolls" every 2, 3, 4, 6, 8, 12, or 16 "steps". It is also possible to add a "roll" with each screen rotation. To synchronize the start of "rolls" on all tracks, use the Reset function (or with Skippy Live), otherwise, each "roll" starts when the option is set (for example, to avoid setting "rolls" per turn all at the same time).

The beat times of the "rolls" depend on the duration of each gate. It is therefore recommended to take a slightly longer gate for the effect to start being noticeable (from 60-70 and up).

The new "proportional gate" function is also taken into account (thus divided by 2 or by 3).

New Proportional GATE

The function that allows choosing the gate length for each track has been extended.

It is now possible to choose it in proportion to the existing time between two beats. This can be very useful for melodic sequences (with Zazou for example).

You can thus alternate between quarter notes and half notes, or eighth notes and whole notes, etc.

Each of Skippy's four tracks can have a different setting, including with variable time functions (GAUSS, POLYR...), which promises infinite explorations.

Access proportional gates by turning the encoder in GATE mode to the left: instead of stopping at 10 as in the previous version, the percentage of active gate time is displayed. You can choose the percentage in steps of 10, from 10% to 90%.

Description:

Skippy is a matrix and non-matrix polyrhythmic sequencer (linear and logarithmic) which offers four completely independent tracks with a very simple interface: one button per track, one function per screen, no sub-menus.

Possible saving of 64 configurations.

Internal connection with expander module (coming soon) and with Zazou, generative composition module (coming end of 2023).
