Notes: The Meng Qi DPLPG is a Dual Passive 1-pole vactrol based Low Pass Gate/VCA in modest 2 HP. No power is required as the design is completely passive.

Handpicked components ensure that the modules will be musical.

Feed it a trigger and enjoy the natural smooth decay of a vactrol.

Notes: Moonwalker is a versatile signal generator that performs as an envelope, lfo, and audio oscillator, with attack and decay time controls

Phase offset is continuously variable from 0 to 360° and inverts the waveform without changing it’s amplitude, and with or without changing it's polarity.

Unipolar mode preserves the output range by offsetting the starting voltage, so it always stays between 0 and +10v

Bipolar mode preserves the starting voltage by offsetting the output range, so it always starts at 0v. The output range will shift from +unipolar, through +bipolar, to -unipolar, through -bipolar back to +unipolar.

The reference waveform does not change phase, but the timing of the rate change between Attack and Decay shift with the phase offset, to ensure synchronous movement.

The phase offset output is half-normalled to the phase offset cv input and skews the waveform from triangle to saw or ramp without changing frequency (when attack = decay).

Notes: BLN is a 4 channel audio level converter designed to interface line or "pro" audio levels to modular audio levels. It features 2 independent converters with 2 channels each.

Converter 1: Line level/Balanced to Modular Level

The inputs for the top converter are for converting -10dB or +4dB signal levels (balanced or unbalanced) to +/-5V modular levels. Each channel can be set individually for +4 or -10 using channel 1 and 2 of the DIP switched

Converter 2: Modular level to Balanced Lined

The inputs for the bottom to converters accept a +/-5V modular audio level and converts them to a BALANCED +4 dB or -10 dB audio level. Each channel can be set individually for +4 or -10 using channel 3 and 4 of the DIP switched.

For balanced signals, simply use a 3.5mm TRS to 1/4" TRS Cable or 3.5mm TRS to 3.5mm TRS cable with a 1/4" TRS adapter. Unbalanced signals should use a 3.5mm TS cable

Basic Usage instructions:

Front:

Voltage Select switches: Independent for each channel. Does NOT affect MIDI/I2C data

Slider LED color: To change the LED color, simply remove the cap and rotate the square LED 180s. Do NOT force the LED back in, it should slide in easily, may require wiggling.

Rear:

Power Header: Standard 10pin power cable, there is NO polarity for this connection. It can be connected either way

MIDI Out Header: This is a 4 pin header but only 3 or 2 connections need to be used. To connect to a DIN cable, either GND, 5 (to pin 5, current sink/aka -), and 4 (to pin 4, current source/aka +) should be used. For internal module to module connections, only pin 4 and 5 should be used. The ground pin is only for the shield in a midi cable, it is never connected on a midi input and isnt necessary for the short module to module lengths

I2C Header: 3 pin header to connect to other I2C devices in your rack, this is an unbuffered connection so cable lengths should be as short as possible (20cm/6" recommended). There are 4.7k pull up resistors on this connection

Module Orientation jumpers: There are 3 of these jumpers which determine how the module operates depending on if the jacks are on top or bottom. They will come installed in the position matching your panel but can be changed should you want to flip it. "INV" is Jacks on Top, the white position is jacks on bottom. Changing these jumpers will change the numbering of the faders from left to right (1->8) in both MIDI and I2C and will invert the voltage response (i.e. 10->0V from top to bottom). The jumper is shown in the "jacks on top" position in the pic below. ALL THREE JUMPERS MUST BE IN THE SAME POSITION for the module to operate correctly.

Module Config DIP switch: This allows you to switch between I2C Follower and I2C Leader modes easily. Simply move the switch to the "lead" position and restart the module (you can press the blue reset button once). The other 3 positions are for future expansion and not currently implemented.

Connector for Expander: This connects the F8R to the I/O expander. The cable is attached to the expander. Note the keyway at the top of the part, the connecter will ONLY connect one way

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.

MIDI Functionality:

MIDI Learn: Press this button and send a midi note. The device will use that channel as the base channel

MIDI Mode: This button cycles between two operational modes.

1. 4 single voices trigger on 4 midi channels starting on the base MIDI channel (i.e. base channel is channel 2 so the voices are mapped over channels 2, 3, 4, 5)

2. Simple Poly mode where each voice plays on a different note on the same midi channel

Note about MIDI and Gating: The gate is normalled OPEN by the Gate 1 input. This is by design but will also force the gate open when the device is triggered by midi. Placing a dummy jack will break the open normal the gate will trigger via MIDI normally

Notes: This is 2 x opensource branches. The input of channel one is normalled to all other inputs so you can run this as 1 to 4, 2x 1 to 2, etc. Dual Color LEDs on sliders

Notes: 6HP Micromodule of MI Warps.

Notes: Hue is an audio colour processing effect, in 6HP eurorack format. Hue is comprised of a chain of 5 effects (Drive, Filter, Tape Saturation, LoFi, Compressor). Each effect imparts a particular coloration, tone, distortion, and/or texture to the source audio. With Hue, Drums bang with more intensity & melodies morph into lush LoFi tones.

Hue's goal is to simply colour your sound. The initial concept was born of a debate about the techniques and processes used to make drum machines sound big, bold, and delicious. The sounds that tug at the hearts of boombap, LoFi, and subsequently modbap, enthusiasts are those that have great texture, lush degradation, soft distortion, and big bold strokes of colour. The classic beloved drum machines were often processed with outboard gear, recorded to tape, pressed to vinyl, played in big booming systems, sampled, and resampled and on and on. Ultimately, those are the sounds that become nostalgic and reminiscent of all that we love about classic LoFi boombap production. Hue is Modbap's attempt at bringing that vibe into eurorack with a cute little 6hp package.

The effects chain audio signal path is as follows; Drive, Filter, Tape Saturation, LoFi, Compressor. The panel layout allows for the DJ style filter knob to sit in first position for ease of tweaking. Drive boosts and lightly distorts the signal, while shift+Drive adjusts the Drive tone. The Filter is a low pass filter to the left and a high pass filter to the right. Tape effect is intended to impart cassette tape saturation, while shift+Tape adjusts the intensity. LoFi adjusts bit depth, while shift+LoFi adjusts sample rate. Lastly, the one knob compressor mini pot serves as the final glue in the signal path that brings it all together.CV inputs for Drive, Filter, Tape Saturation, and LoFi opens loads of creative possibilities. Hue is a textural beast when creative modulation is thrown at it.

Hue puts the power to shape and transform your sound at your fingertips. It's great for beefing up drums and equally as magical on melodic content. Hue can be the glue that brings it all together. It also, pairs well with Trinity and Osiris. All in all, Hue exemplifies the tagline "Made for eurorack, dope enough for boombap!"

Notes: Unique hands-on performance effects module inspired by DJ gear, featuring colour processing, compression, reverb, glitch and much more besides. Great sound and lots of CV options.

Supplier's Notes:
Per4mer is a 14hp eurorack formatted quad performance effects unit. Inspired by time-honored DJ effects processing boxes, Per4mer allows for a hands-on and CV / Gate controlled eurorack effects performance interaction. Whether momentarily engaging or latching FX, Per4mer offers an unrivaled and fun experience.

The basic principle of Per4mer is to feed in an audio input and to trigger on-the-fly effects, bringing DJ style live improvisation to a modular environment. Effects can be triggered simultaneously or individually where an inspiring effect palette combines to generate unique creative beats and melodies.

Per4mer includes 4 performance effects (Delay, Reverb, Glitch, Tape Stop) and 2 processing effects (Color processor & Compressor). Each of the 4 performance effects has its own set of 4 parameters controlled by the 4 knobs or CV inputs. Effects can be used simultaneously or individually allowing for a vast variety of creative effects combinations.

The Color processor allows for engaging any of the 4 coloration presets - Classic (12bit), LoFi (8 Bit), Saturation, and Wax. Combine any one of these color presets with the onboard Compressor and Side-Chain input to instantly transform any audio signal's mood and vibe.

Engaging the Reverb along with the "12-bit classic" color option gives an incredibly lush lo-fi reverb sound while disengaging the color option allows the reverb to remain just as beautifully lush and hi-fi. The potential is nearly limitless.

Per4mer's 'Glitch' effect is inspired by classic beat repeat and looper effects offering 4 controls - Wet/Dry (sound on sound), Loop size, Pitch, and reverse. Conversely, the Tape Stop effect allows for the perfect punctuation of any audio signal.

Notes: Transit has two stereo (dual mono) channel lanes of audio with an all-analogue signal path. Each stereo channel lane has its own input gain control, mute button and ducking input. The Ducking input on each channel operates like traditional sidechaining on a compressor where an input signal, CV or Trigger input (i.e. LFO, Clock, Gate) modulates the gain reduction of the audio.

Transit offers a main stereo output controlled by the master volume control knob and an independent 3.5mm headphone output controlled by its own headphone level control knob.

Digitally controlled LEDs for each stereo channel lane indicate level via white, blue and pink illumination while engaging mutes illuminates the LEDs with the color red. Master and headphone levels also have their own LEDS for level indication using the same color scheme of illumination.

All in all, Transit is a rather full features compact 6hp dual stereo channel lane eurorack formatted mixer that offers easy signal mixing, gain staging, ducking, and performance-oriented mutes. Transit is just as at home in a small eurorack system as one Transit or several would be in a larger system.

Notes: Based around the logical assumption that a decent drum pattern starts with kick, snare and hi-hat, the Trinity is a three-voice digital module designed to cover all the main elements. A lot of versatility in a nice format.

Supplier notes:
TRINITY is a 3 channel Digital Drum Synth Array packed into a 20hp eurorack synthesizer. Effectively, Trinity performs as 3 powerful drum voices packaged into one beastly drum module with a few tricks up its sleeve.

The name Trinity refers to the 3 drum channels and tips its hat to the core elements of any modern beat driven composition which is typically Kick, Snare and Hat. Trinity takes this simple idea and flips it on its head with 3 channels and an array of drum synth algorithms that use various types of synthesis (Analogue Inspired, Additive, FM & Noise) allowing for a wide array of drum design capability that achieves and reaches far beyond the conventional. Trinity's array of digital drum synth algorithms are very malleable by way of the 7 knobs and 4 mini-pots, each of which control a specific parameter and characteristic (Pitch, Sweep, Time, Shape, Grit, Decay, EQ, Clipper, Hold, Volume and Character) for each drum voice. Each drum channel has its own trigger and v/oct in addition extensive CV input options per channel.

Trinity takes its capabilities a few steps above and beyond most with the addition of its Cycle modes (Round Robin& Random) and Stack modes (2 Stacks & 3 Stacks).

Round Robin cycle mode cycles through the drum algorithm types one after another with each trigger. Random cycle mode randomizes the parameters of a channel's chosen drum algorithm type with each trigger.

Stack modes are inspired by the characteristics of chopped breaks where drums tend to overlap and fan out depending on the content of the chopped source material. Trinity's take on it? Stack modes allow 2 or 3 drum channels to be triggered by the primary channel's trigger and v/oct inputs. 'Stack Spread' allows for fanning the stacked drums out to taste.

Trinity's uniquely performable and switchable output matrix allows for the routing of each drum channel's output to the mix output, the individual drum channel output or both. This makes for easy performability, mutable output, parallel processing, or side chain source.

Lastly, Trinity's midi over USB connection allows for midi control over various parameters via one USB cable. USB midi makes integration a cinch by connecting one USB wire from Trinity to a groove-box or computer-instant integration.

All in all, Trinity packs a hefty punch and weighs in at 20hp, 11 knobs, 3 drum channels, 3 trigger buttons, 4 drum synth algorithms based on 4 different types of synthesis, 24 CV inputs, 3 way output switching with 3 individual outputs, a mix output and a midi over USB connection.

Notes: Sindikat is made to be placed in the heart of every modular setup: copy, invert, attenuate, scale, get different polarity versions simultaneously of two pair of mixes, mix CV as well as audio (up to 8 sources in total), mute or switch to add desired source to a bigger unity mix, scale two separate mixes with chosen gain.. All circuits can preserve their independent use and/or be combined!

Details & use:

The module consists of circuits designed to group the most useful operations for signal mingling in modular synth setups -but in the more fun manner!

It is designed in the way that the circuits can function independently -be patched to the other modules- or to be combined inside the module at the same time!

On the top of the module there is a buffered multiple (the bi-color led is indicating signal input and its polarity) : Next to the input there are two outputs giving the exact copy of the incoming signal. On the third output you'll get the 'attenuverted" version of that signal which is controllable by the dedicated attenuator/inverter potentiometer.

This signal can be further added (or muted) via its switch, internally to a unity gain mixer situated on the bottom of the module via its SUMM OUT.

This mixer has its own 3 inputs who will accept CVs as well as audio signals with an output gain of 1/3.

Its bi-color led will indicate the polarity of the incoming signals.

In the center of the module there is a CV Processor consisting of two mixers each mixing two signals- in the way that:
The first one takes two signals (A and B) and outputs simultaneously the positive version of their mix (AB+ OUT) and the negative version (AB- OUT).
Their gain is scaled by the potentiometer: going on 1x in the middle position to 2x fully turned. (After middle position with a stronger signal and due to higher gain it will start to saturate producing an distortion-like effect)
Further, via their switch, those mixes also can be added to a unity gain mix (SUMM OUT) and therefore creating a larger mix.
You'll do that by choosing which polarity output you want to send to a summing mix.
In the middle position of the switch the signal is "off" so you can use this to mute/un-mute the signal in the unity mix. Also, even if it is in "off" position this only breaks the internal link to a unity mix but you can still use their distinctive outputs to send your positive and negative mixes elsewhere in your system.

Goes the same for the second one: C and D inputs giving positive (CD+) output result and negative (CD-) simultaneously , all with gain select and the switch choice for summ positive or negative (or none) to a bigger unity mix.

You can also choose to use those two circuits as a simple attenuators for ex. by patching only one signal so you'll get an attenuator and polarizer at once!

The module can process CV and audio as well in every circuit.

Therefore, by summing eventually all the signals to a final "SUMM OUT" output you can create up to 8 sources -in the module- large mix!

Made for more fun with a modular!

This module fits perfectly well with Modulaire Maritime "Decca" switch-based manual control module.

As these modules are developed from practicing recording in "one take" (same for a live performing), combining them you get an extended control over CVs, gates and audio going on in the system, allowing to switch- stop/mute, change polarity, introduce/mix more gates, drums,.. on the fly.

Notes: The MST Unity Gain Mixer adds input signals together and combines them for a summed output. For example, if you put in a 1V source and a 3V source, the output will be 4V. It's mainly used for CV, but it can also be used to combine audio signals together.

A unity gain mixer is handy in several ways:
Combining gates and triggers. Plug a few sequencer steps into the unity gain inputs, then run the output to a drum synth, VCA, envelope, etc.
Re-shaping two CV sources with a single envelope.
Combining different wave shapes or LFOs to make crazy sounds.
Controlling the CV of one source with the CV of another source. Just plug the CV out of a sequencer into and an expression pedal/touchable CV out into the unity gain inputs.

Notes: Designed to be a highly customizable connection matrix, 3DVCA packs a boat load of utility into a small 6HP package. Four VCAs share the three macro controls: X, Y, and Z. As a group, they shape incoming and outgoing signals and emulate the coordinates of a point in 3 dimensional space. This allow the VCAs to work together in a mono, stereo, or quad configuration and accomplish a variety of mixing, crossfading, and panning functions.

3DVCA is designed to be used in the following functions:

Quad monophonic crossfader
Dual stereo crossfader
Stereo balancer
Stereo VCA
Mono to stereo panner
Unity mixer with up to eight inputs
Quadraphonic panner

Each output has a dedicated SUM input which allows an external signal to be automatically mixed into the output signal. This allows 3DVCA to daisy chain both with other mixers and other 3DVCAs. For example, you can create a full mono, stereo, or quadraphonic mix by plugging the output of each 3DVCA into the sum inputs of the next 3DVCA in the chain. Using this method, a set of 3DVCAs can create a fully voltage controlled and decentralized mixer which ties together anything from a small skiff to a monster synth.

When 3DVCA works as a crossfader or panner, the X and Y parameters follow an equal-power curve that keep output signals at the same volume no matter how many inputs are mixed together. This is in contrast to the Z parameter which follows a linear curve to always behave predictably with external modulation sources. All inputs are fully DC coupled in order to work with modulation speed signals as well as static DC voltage sequences; this means that 3DVCA can handle any sort of signal that you throw at it. All op amps in the device employ rail-to-rail inputs and outputs to enable the largest headroom when mixing many different signals together.

Whether you need to maximize your mixing functionality in the smallest possible footprint or have the most control over every aspect of your system, 3DVCA provides a ton of functionality in any system. Enter a higher dimension of sound with the Mystic Circuits 3DVCA.

Notes: Instant IDM! An unusual genre-specific module from Mystic Circuits, automatically generating complex trigger sequences. Create loops or apply real-time effects to a trigger or gate input.

Supplier's Notes:
IDUM is a gate processing effect that turns its input effortlessly into IDM. Making complex electronic music with the modular usually requires meticulous sequencing done in advance or a large ecosystem of modules. Unfortunately, the level of expertise needed to accomplish this is not accessible to the average modular user. IDUM aims to make this process easier and put Intelligent Dance Music, also known as IDM, into the hands of people with average intelligence. IDUM does not require much knowledge to get immediate and compelling results; but with some extra familiarity, this module can enable innovative music making techniques. Instead of generating musical patterns on its own, IDUM acts like an effects processor for the sequences that run through it. For example, a filter or a delay allows the user to alter their sound by twisting the knobs or modulating the parameters. Similarly, IDUM manipulates the actual gates and sequences of connected modules, but with a level of playability normally inaccessible to a sequencer. IDUM can vary carefully crafted sequences or turn your music into an onslaught of controlled chaos. Its open source code and hardware based on the beginner friendly Arduino Nano Every encourage users to tweak their modules to taste or to add new features all while ensuring future improvements as IDUM makes its way into the wild.

IDUM has eight effect modes:

HOLD - Alter the length of incoming triggers.

BURST - Generates a ratcheting effect with timing determined by the clock.

MULTIPLY/DIVIDE - Generates a ratcheting effect with timing determined by incoming triggers.

BALL - Generates a bouncing ball effect.

ROTATE - scrambles the connections of inputs and outputs.

DELAY - postpones incoming gates by a dynamic amount of time based on incoming triggers.

BREAK - preset rhythms that turn incoming triggers into breakbeats.

SKIP - manipulates the clock output to multiply the clock speed or skip forward multiple steps.

In addition to these modes, IDUM features an eight step looper that loops incoming gates as well as any effects that were active on those steps.

To control when IDUM's effects are active, the CHANCE slider sets the likelihood that on a given step an effect will activate and the LENGTH slider sets how many steps the effect will last for. The PARAM knob controls a parameter unique to each effect while the MODE knob selects the mode. All of these controls as well as the LOOP status have their own CV modulation inputs.

Unique to IDUM is its ability to manipulate external sequencers using the clock output. This includes functions like: pausing the clock when an effect is active for dynamic clock division, skipping forwards or multiplying the speed of the clock in SKIP mode, and looping a sub-section of sequencer steps in the looper. To keep everything tamed while manipulating the clock, the CYCLE switch will send out bursts of clocks to catch your sequencer up with its original sequencer position after an effect has completed. Keep in mind that not all sequencers like to be clocked fast enough to work with these features, so for best results pair your IDUM with a TREE/ LEAVES combo from Mystic Circuits.

IDUM might be the stupidest way to make IDM and Mystic Circuits are proud of that. Whether you want to add complexity to your dance floor bangers or make the most obtuse and unlistenable music imaginable, IDUM is here to help. See just how dumb your music can get with the Mystic Circuits IDUM.

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

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

4 different sliders

RATE

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

PROB

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

RND

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

SHAPE

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

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

Internal random clock source

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

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

External IN & TRIG inputs

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

Self-modulation

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

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

SHAPE Outputs

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

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

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

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

Notes: Warp is a novel synth engine that combines the best of additive and wavetable synthesis.

In the center of Warp's control panel is a colorful XY LED matrix that represents the sound space from which Warp draws its sounds. This XY sound space consists of 32x16 frequency spectra. Each of Warp's four voices can move freely and independently across the XY space. It always uses the surrounding frequency spectra to calculate a wavetable based on 512 sine waves in real time using additive synthesis. By changing the position, wicked wavetable sounds are possible, playable with four voices and eight oscillators and navigable in two directions. An intuitive integrated editor allows playful modeling of your own frequency spectra.
With Warp's SPEC effects the frequency spectrum can be filtered and deformed in realtime before a wavetable is calculated. The wavetable can then be modified with WARP effects like wavefolder, PWM bend, overdrive and redux. The resulting wavetable serves as source for two oscillators per voice, which can be detuned and also synchronized to each other. Each voice is followed by a 12/24dB/octave high pass and low pass filter.

Warp offers an integrated editor, with which you can playfully draw and modify your own frequency spectra. The XY-Sound Space is seen as a canvas on which you can draw your own frequency peaks. Several drawing algorithms are available as tools to edit single or a group of harmonics in a musically meaningful way. There is also the possibility to derive frequency spectra from audio samples from the SD card or to put whole wavetable audio files into the XY sound space. Likewise, the XY sound space can be exported to the SD card as a wavetable audio file of any length and bit depth, so Warp can also be used as an intuitive wavetable generator for other synthesizers.

Also on board are two internal ADSR envelopes and two LFOs, which can be routed to a variety of internal destinations using a modulation matrix. To keep the overview, all modulations are color-coded and are additionally visualized by pulsating LEDs in the modulation matrix view.

Navigation through the menu is as intuitive as with our QUASAR module and is simply done via a push-encoder and a back button. The display always shows which function the four surrounding aluminum encoders currently have, and colored LEDs next to the encoders provide visual assistance. Likewise, the tuning of the module is done via a detented encoder, which adjusts the pitch either in fine steps, in semitones or in octaves. An octave switch is thus already integrated.

For all its feature-richness, Warp still remains a playable and performance-oriented instrument. The large potentiometers serve as macro controls to control several parameters under the hood at once. This keeps the instrument straight forward with a manageable number of controls, but they are all very expressive.
Likewise, the module offers the ability to save and load presets and also comes with audio files and presets on board. Thus, Warp is ideally suited for both detail-oriented sound design and hands-on performance.

In the standalone version, Warp is a monophonic four-voice synth voice that can also be used as an oscillator. With an expander module, it will also be possible to play Warp four-voice polyphonic via MIDI and CV/Gate in the future.

Warp uses a novel hybrid engine that combines the best of additive and wavetable synthesis. With the integrated editor you can playfully draw your own frequency spectra like on a canvas into the colorful XY sound palette. Warp is a feature-rich powerhouse that lets you create all kinds of sounds, from glassy clean to crunchy crunch. Thanks to expressive macro tone controls, extreme morphs are possible in a single pot turn.

Notes: Babel is a tool for creating massive intermodulation, and a workhorse for analogue logic, depending on your use and interpretation of its function. It provides three inputs, which can be arbitrarily increased with the chainable expander (see below). For each of those inputs, Babel outputs the maximum value (ANY), the minimum value (ALL), and the balanced middle value (XSOME), which follows along the centre values of the input waves. What CENTER means is adjustable via knob and CV control. XSOME is particularly interesting, as it has the same general shape as a multiplication function, but with sharper edges. What this means it that Babel will create ring-mod like intermodulation-but with extra harmonics like those produced with a wavefolder, and with an arbitrary number of inputs, instead of just two.

When viewed as a logic module, Babel takes any group of truth values and tells you whether any of them are true (ANY, the equivalent of "or" with just two values), whether all of them are true (ALL, the equivalent of "and" with just two values), and whether some, but not all of them are true (XSOME, the equivalent of "xor" with just two values). Turn CENTER all the way to the right for 0-+5V logic, or leave it cantered for -5V-+5V logic-handy when your "logic" modules are really LFOs.

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.
