Synth modules

Notes: The Dystopia is ideal for complex patches where sound can be used to thicken the sound or filter out frequencies. It features a noise generator which can provide white, white to pink, white to blue, scatter, digital, pitch types of noise. The digital noise is brilliant as it can be used as a random gate generator. The bit crusher stage can range from one second up to 8kHz - meaning you can obtain really thick distortions - ideal for a range of styles of music. You can reference all the signals through the four LEDs too - which help you determine the level at which the module is pumping out the noise sources.

Notes: Nive Grad is a level shifter designed for simplicity. Two Eurorack signals can be attenuated down to pedal and line levels, and two external line or pedal signals can be amplified up to Eurorack level. Integrating a drum machine, external synth, effects processor, or guitar with your Eurorack system has never been easier!

Nive Grad uses 1/8" jacks to save HP. If you want to use 1/4" gear with your system, ask your modular supplier about mono/TS 1/8" to 1/4" adapters or adapter cables.

Nive Grad pairs well with Noise Engineering's Xer Mixa system mixer, but can be used in any Eurorack system.

Notes: The Morphor Sequencer - Quad Gate/CV is a versatile tool for both live Eurorack performances and songwriting. This module can be configured as a 2-, 3-, or 4-track sequencer, depending on the selected output configuration. With flexible track configurations and intuitive real-time step editing, this sequencer offers a handy approach to sequencing in modular systems being only 4 HP wide.

Whether you're controlling gates, CVs, or a combination of both, this module adapts to your creative needs with ease. Key features include up to 4 independent tracks, each capable of holding up to 16 pages containing up to 16 steps. Users can configure tracks as gate, CV, or combined gate/CV tracks, and even set up triad chords. The module supports customizable step lengths, glide times, individual track playback orders and reset behaviors making it ideal for creative sequences.

This module can operate as a standalone unit using its internal clock or be easily synchronized with an external clock source for integrated use within a larger system. The clock and reset jacks can function as both inputs or outputs, allowing flexible configuration to match your setup.

For expanded setups, multiple Morphor Sequencer modules can be daisy-chained via the bus connection on the back, ensuring that clock and reset signals are shared seamlessly across all connected modules. This makes it easy to sync multiple sequencers for complex, multi-track performances or compositions.

Notes: Packed with powerful features while maintaining intuitive playability, Strymon's Magneto module is a stereo multi-head tape delay that also functions as a looper, phrase sampler, vintage spring reverb unit, phase-aligned clock multiplier, chaotic oscillator, zero latency sub-oscillator and more, with extensive CV I/O.

Turn simple monophonic signals into complex orchestrations. Create new oscillator tones using self-oscillation. Add rich stereo dimension to your sound, and enjoy the inherent warmth and sweet, subtle distortion characteristics of magnetic tape. Magneto transforms even the smallest rack into a fully expressive, immersive instrument.

To capture the full experience and complexity of a vintage tape echo machine, every last tape system attribute was relentlessly studied and faithfully recreated. From the sought-after natural saturation and soft clipping of magnetic tape when driven hard, to hands-on real-time controls for tape age, tape crinkle, and mechanical wow and flutter, Magneto delivers a rich multi-head delay experience that adds life and vibe to your sound.

Every function, control, gain stage, and signal path component in Magneto works together to respond musically and smoothly, even during the wildest live modular improvisations. All this is combined with a luxurious spring reverb to take the sound of your modular setup to a new level, and your sonic explorations into far-out territories.

Not only does Magneto deliver the warm, luscious delay signals that tape delays are known for, it is also capable of a high degree of saturation. Turn up the Record Level knob to send a hot signal to the record head for any amount of tape saturation you desire. Turn up the Tape Age control for warmer repeats. Add some truly beautiful Spring Reverb. Magneto adds organic heart and soul to the sound of your modular.

The effect of the Low Cut and Tape Age knobs are explored, followed by the mechanical 'deterioration' of the machine with the Crinkle and Wow and Flutter controls. The Speed knob is put to use for sonic enhancement.

In a typical digital effect the dry signal gets converted to digital, causing conversion noise and latency. Signals are often attenuated before combining digital dry and wet, with makeup gain amplifying the conversion noise. To avoid this scenario, Strymon have equipped Magneto with a completely analog dry path. Why go to all this trouble? Because the improvements in dynamic range and reduction in noise are so dramatic.

Strymon have outfitted Magneto with the powerful Analog Devices SHARC ADSP-21369 processor, which provides a 366 MHz core instruction rate, and an incredible 2.4 Gigaflops of peak performance. Thanks to this high-powered technology platform within Magneto, we had the freedom to craft our processor-intense tape echo algorithms without compromise.

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

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

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

Notes: A powerful utility module:

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

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

Notes: An unusual but enticing form of generative music in Eurorack, Kaona's Zazou module offers MIDI or CV sequencing based on a series of algorithms, allowing you to define parameters and generate melodies and patterns of up to four tracks.

Supplier's Notes:
Zazou is a generative music module based on numerous configurable algorithms. It acts as both an accompanist capable of syncing to a regular sequence and an improviser within a given framework. Its function is to produce notes: no sound comes directly from Zazou, as it's intended to be connected to one or more synthesizers or other Eurorack modules.

It features both a multitimbral MIDI output and Eurorack-compatible CV outputs.

To generate notes, Zazou requires "gate" signals to trigger each note. Therefore, it follows the rhythm imposed by a sequencer or any generator producing gate output. It pairs ideally with Skippy, Kaona's algorithmic rhythm generator.

Zazou produces music based on the equal temperament scale and follows the note division corresponding to keyboard instruments (piano, organ, etc.). Thus, in Zazou, as in a piano, a C sharp corresponds to a D flat.

Zazou produces notes on four independent channels that can nevertheless be tuned together.

Interface

Seven CV inputs:
One gate per channel: red, yellow, green, blue

One "Reset" input: realigns the tracks, resets the sequence, interrupts all MIDI notes currently playing.

One "Change" input: allows external sequence control.

One "Play/Stop" input: stops (or restarts) all produced notes and pauses the current sequence. This input also measures an external beat to determine the quarter note value (BPM) that Zazou will use (this value can also be set manually). The input can be a clock (set to one beat per quarter note) or a sequencer.

Seven buttons:
One per channel, matching its colour: they function differently depending on the displayed screen. (Selection, Pause, or Manual Gate).

One Play/Stop button: stops or starts all tracks simultaneously.

One "Change" button: manually advances the sequence.

One "Reset" button: realigns the tracks, resets the sequence, interrupts all MIDI notes currently playing.

Three encoders:
Their functions vary depending on the displayed screens.

One MIDI output:
The output is in TRS format. It's possible to choose between cable A or B using a switch on the back of the card.

Twelve CV outputs:
Four "gate" outputs: mirror the input signals but add ornamentation notes.

Four CV outputs: export velocity (selectable between 5V or 8V).

Four Note outputs: in 1V/octave format, across 10 octaves.

Basic Functions
All functions are identical for each channel but can be synchronized according to your composition criteria.

Root Note: determines the key each track plays in.

Scale: constrains Zazou to adhere to a given scale (22 scales available).

Sequence: dictates that the composition follows a given sequence.

Algorithm: allows the selection of melodic behaviour.

Sequences
It's possible to instruct Zazou to follow a sequence track by track, but it's often more musical to let the four tracks follow a single sequence. For example, you can choose the common II-V-I progression or the circle of fifths, but also use less common sequences. The sequence behaviour can be customized by selecting the number of notes in the sequence, passing notes, alternating major and minor chords, etc.

Algorithms
The algorithms determine the note behaviour for each track.

It's possible to freely mix algorithms track by track, choose the same algorithm for all tracks, or the same algorithm for all tracks but with different behaviours.

Depending on the chosen parameters, they will generate more or less repetitive, varied, or complex melodies. Even though each note depends on an external gate, some algorithms additionally produce ornamentation notes like triplets or appoggiaturas.

Random:
Allows for completely random and unpredictable operation. However, one can influence how randomness occurs by changing event frequency or velocity, for example.

Walkingbass:
Walkingbass precisely follows the sequence in a classic Jazz walking bass manner, with one quarter note per beat. Numerous forms are offered, and it's possible to enrich the progression with ornaments or emphasize strong or weak beats, for example.

Arpeggiator:
Several types of arpeggios are available, and it's possible to choose direction (including random), chords used, ornaments, and their frequency, etc.

Intervals:
Starting from a reference note chosen within the scale, Zazou will traverse a selected number of octaves and notes according to a given interval.

Serial:
Zazou will generate note sequences respecting the rules and principles of serial music. All theoretical parameters are available to practice the specific genre of dodecaphonic composition (inverse sequence, retrogrades, etc.).

Cantor:
The Cantor set starts with a segment (the complete range of available notes) and repetitively divides it, eliminating central segments. This creates a more or less detailed repetitive pattern depending on the chosen parameters.

Fibonacci:
The Fibonacci sequence is used to calculate note heights within a scale starting from a chosen note and modifying it according to selected Fibonacci numbers. Interval modulation allows staying within a playable range while exploring rhythmic and melodic patterns generated by the sequence.

Sierpinski:
The approach divides an octave into three equal parts (triads) and selects two for repetition, imitating how the Sierpinski Triangle is drawn by removing the central triangle and repeating the process on the remaining triangles. This divides the musical space according to the specified depth and plays notes based on this division, simulating the repetitive structure of the Sierpinski Triangle.

Mandelbrot:
The Mandelbrot set is one of the most famous fractal objects. Zazou maps this set into a musical representation to offer unique and varied sound structures. Since calculations are done in real-time, parameters can vary the melody's behaviour infinitely.

Julia:
Like the Mandelbrot set, the Julia set offers fertile ground for musical experimentation, with opportunities to explore fractal complexity through sound. Julia sets are defined in the complex plane and produce complex fractal patterns. Here too, real-time calculations allow parameters to vary the melody's behaviour infinitely.

System Functions
It is possible to choose a corresponding MIDI port for each track. Depending on your setup, you can use Zazou in polyphonic mode (same MIDI number), multitimbral mode (one port per channel), or multichannel mode (multiple synthesizers).

The quarter note duration (BPM) can be adjusted manually or automatically (clock signal, sequencer, etc.).

For all algorithms, you can choose the note duration proportionally to the quarter note value or match this duration to the incoming "gate" duration for each track. Thus, it is possible to play very dynamically with a variety of connected instruments as long as they provide a "gate" signal.

The velocity value can be selected within the range of 0V -> 5V or 0V -> 8V depending on your modular equipment.

Zazou operates across 10 octaves, in MIDI or CV (1V/oct) for modular use. However, it is possible to limit the number of octaves, either to accommodate synthesizers that poorly support very high notes or to limit the voltage in a modular environment.

Two settings allow adjustment of the overall pitch and fine interval between notes (only for modular use).

Saving
The internal SD card allows you to save, within its capacity limit, either track parameters (and load them for another track, for example), sequence parameters, or the entire composition.

Notes: The uFM is an oscillator module, that is focused on FM synthesis.

It's basically a two-operator FM synthesis, but with extended functionality: The operator waveforms can be either sine waves (classic FM), or four other different combinations of non-sinewave waveforms, that produce a much broader palette of sounds beyond the classic sinewave based FM synthesis.

The MOD DPT knob controls the modulation depth; in combination with a button press also the multiplier of the modulating operator can be defined.

Both parameters can be controlled also by CV and also via IMDI by MIDI controllers. The pitch can be controlled via 1V/octave CV or also via IMDI e.g. from a DAW

(For IMDI, see IMDI HEART for more info).

Additional to the normal audio output a suboctave output with a squarewave is provided, and a third output with the mix of the primary oscillator signal and the suboctave.

Quite a lot for such a tiny module, right?

Please note: These micro module needs a carrier, like the uBASE module. The cannot be mounted directly into an AE case.

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

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

Notes: Really clever stuff here. The Octaves VCO takes an additive approach, layering harmonics on top of a fundamental frequency to create complex tones. Control the six bands via CV to adjust the harmonic content.

Supplier's Notes:
A harsh and funky take of an additive Oscillator.

Pile up multiplications of your frequency to get a lo-fi-retro wall of squared sound!

You get six doubled frequency pulses, or octaves, with common PWM and volume control for each of them.

The output of each is cascaded to the next one, so you can either have one output with all frequencies or break the chain and get several sums and modulate each independently!

Notes: Welcome to the Rosci soundscape. Rosci is a digital VCO that generates random waveforms to create unique, rich, and full sounds. You are able to control how complex the sound is-add harmonics and have a completely unique shape generate using the generate button/trigger. BUT, it can also be tuned to output basic waveforms (sine, square, sawtooth) if you so desire.

Tunable parameters breakdown:

COMPLEXITY: Essentially a generation of unique timbre.
ROUNDNESS: Set the basic shape of your waveform. Go from from sharp to soft sound, similar to filtering.
HARMONICS: Add up to 6 harmonies to your sound. The choir's here.
FORMANTS: Accentuate certain overtones in your sound (like a voice singing "ooo", "ahh", "eee").
DETUNE: Add a classic 'detune' with a changing phase wave for extra wide sound.

How does it work?

It is a pipeline of algorithms, which generates and modifies a waveform starting from top to bottom. Rosci works on a principle of key points: the generate button generates key point location and amplitudes to be passed down the pipeline.

Tunable parameters:

Beginning with complexity, you set the number of key points (even numbers only to create a waveform). Lowest complexity sets two points, and highest complexity sets up to 20 points. The number of key points will vary with each waveform generated. From there, the roundness sets the type of interpolation of the key points, from square to sine. Adjusting the harmonics creates copies of the waveform and adds them to the original waveform at double, triple, ... up to 6x the base frequency. Formants maintains the frequency of the wave, but squishes it so there is 'empty space' in between (this is also called pulsar synthesis). Finally, detune copies the waveform and 'detunes it' by increasing the frequency ever so slightly. And there you have it: a unique Rosci soundscape :)

Notes: The Mutant Rimshot is a fully analogue rimshot and clave generator inspired by the rimshot found in the legendary 909 drum machine; a triple bridged-T oscillator coupled with a state variable filter. The clave sound (not a feature of the original 909 rimshot) is achieved by using just one of the oscillators.

Features

Three oscillator modes

Rimshot HI mode brings classic rimshot sounds
Rimshot LO gives a lower pitch range; try playing with the filter on this setting to get low tom and kickdrum sounds.
CLV (Clave) mode uses just one of the oscillators to give you a brighter, higher percussive sound.
A switch on the back lets you select between original and extended pitch modes. Original mode can give you rimshots exactly modelling that of classic machines (in Hi mode), whereas extended mode gives a wider range of pitch, at the expense of classic accuracy.

Three filter modes

Use the lowpass or highpass filter modes for classic sounding rimshots
Highpass and bandpass can give a wider range of clave and rimshot sounds, as well as completely different percussive elements (especially when turning the resonance up!)
VCF IN lets you blend the clave or rimshot with other sounds. Try adding some filtered noise for a more acoustic sounding rimshot, or for pseudo-snare type sounds.

Novel decay and filter mod controls

The MOD DECAY envelope controls the decay of the VCA envelope
The VCF MOD attenuverter allows you to modulate the filter cutoff with the MOD DECAY envelope
Alternatively, a switch on the back lets you modulate the filter cutoff with the pitch-controlled internal VCO, for filter FM style percussive hits.

Notes: The Grand Terminal is a digital multipurpose module. Its two function generators can be used as envelopes, LFOs or VCOs. The 2 filter channels individually offer 8 modes of operation, and combined with its mixing and routing capabilities and a multi effects unit, it is not only a complete back end of a synth voice, but can also be used as a synthesizer voice, stereo filter bank or general purpose sound effects processor.

The Grand Terminal is based on an ARM M4 DSP, audio resolution 48 kHz/16Bit. Its two filter channels can be used in parallel or serial, and there is a link mode for stereo operation. The Audio inputs have individual trimmable gain stages to integrate the Grand Terminal into different production environments. There´s a soft clipping feature in order to prevent unwanted distortion. Gate A is normalized to Gate B for easy parallel processing.

Each of the filters can be set to any of 8 filter types, which are: Transistor Ladder Filter (Low Pass), Diode Ladder Filter (Low Pass), Vactrol Low-Pass Gate, Resonant Vactrol Low-Pass Gate, State Variable Low-Pass Filter, State Variable High-Pass Filter, State Variable Band-Pass Filter, Comb Filter. The filter can be controlled in 2 parameters manually as well as via CV. The outputs of this section can also be controlled in Volume and Pan position. At this stage, the unit is designed to distort in the upper third of the gain control setting.

The built-in multi effects processor features eight algorithms which can be altered in 2 crucial parameters and a possibility to crossfade between the dry and the effected signal. Its algorithms are: Hall Reverb, Shimmer Reverb, Room Reverb, Spring Reverb, Ping-Pong Delay, Tape Delay and Chorus. At the end of the audio path, there´s a Master Volume Control as well as one Mono and one Stereo output.

The two function generators can operate as AD or AR envelopes. All time parameters can be set between 1 ms and 10 seconds, manually as well as via CV. The envelopes can be individually set to loop and then act as LFOs or VCOs (following V/Oct for about 6,5 octaves). They also feature End-of-Stage Outputs.

When used in connection to the Gateway, all controls which are normally set by jumpers on the back of the module are accessible from the Gateway´s front panel.

Notes: The Dual VCA is a 2hp 2 channel Analog VCA and Mixer Eurorack Module available as a Eurorack DIY Kit, PCB and Panel, or Built Module.

It is a DC coupled OTA(LM13700) Dual Linear VCA based on the same fabled design of the VnIcursal VCA. The 2 VCAs are summed together so it can be used as a voltage controlled mixer at the "SUM OUT" or all 3 outs can be used separately and simultaneously. 5 volts into the CV in will provide unity gain, anything above 5 volts can clip the input.

Notes: 221.x2 is a clean and precise utility module that is equally at home mixing Control Voltage as it is audio. At its simplest, it is two independent 2-to-1 mixers that offer per-channel attenuation and inversion, as well as +6dB of gain available at the summed outputs. With a tap of the "All Mix" button, these separate mixes can be combined into a 4-to-1 mix at the "All Mix" output - meanwhile, the first 1+2 mix is still available at its respective summed output. A rear expansion input and output allows for combining multiple modules into larger systems.

In addition, each channel also offers a Direct Output that can be taken pre or post attenuation/inversion.

A 6-volt offset is normalled into the input jacks of channels 2 and 4. This voltage is available at the channel's Direct Output, as well as added to the mixed outputs. Useful as an offset for mixing with another CV signal, or simply as a voltage source.

Each summed output group has two blue LEDs for displaying the shape of the summed CV, and can also serve as signal present indicators for audio. Peak LEDs trigger at ~9.6V, allowing for a bit of headroom before things get out of hand.

Notes: Polyphonic sequencing from Elektrofon, the Klang allows you to program and perform chords and multi-layered harmonies. Circular clock-style display gives visual feedback and real-time indication of chord progressions.

Supplier's Notes:
«Klang» is a 4 voice polyphonic controller. It stores, traverses and manipulates chord progressions.

Overview

«Klang» is a unique take on polyphonic control within Eurorack.

Displaying chords in a circular clock-like display, and giving the user immediate control over every aspect without "menu diving" makes for an easy to use and inspiring module.

The module can store up to 99 chords, where each chord is made up of 4 voices.

Each voice is represented by a colored indicator on the clock-face which in turn is controlled by an encoder.

The indicators points to notes on the chromatic scale drawn in 360- around the clock-face.

Interface

The big grey encoder in the middle of the module lets you browse the chords - the active chord and total chord count is shown just above the encoder on the display.

The + button lets you ad a new chord. The new chord is added after the currently active chord, and the new chord is then set as the active chord.

The - button removes the current chord.

Inputs

The module has 3 inputs - 1 trigger input and 2 bipolar CV inputs.

Trigger input

The trigger input triggers a chord change.

If the direction input is unconnected, a single trigger results in a single step in the forwards direction.

Direction input (+-5V)

The direction input normalizes to a single step in the forwards direction.

You can feed this input a bipolar CV (+-5V).

Direction maps the total chord count to 5V. This means that +5V results in a single trigger progressing +n steps, where n is the total chord count.

A negative voltage will do exactly the same but resulting in backwards stepping.

0V equals no movement.

Transpose input (+-5V)

This bipolar CV lets you transpose the current chord up or down within 1 octave.

It is therefore a 5V/oct input.

The reason for this is that it is intended to be used with an analoge voltage source like the Pressure Points from Make Noise, or any other analoge sequencer.

It is much easier to fine tune a 5V/oct signal with a regular potentiometer than a 1V/oct signal.

Outputs

Each voice has a separate color coded 1V/oct CV output.

Notes: Simple to look at but deceptively powerful, Dreadbox's Telepathy is a full analogue synth in a small module, featuring VCO, low-pass and high-pass filters, LFO, envelopes and VCA.

Supplier's Notes:
Telepathy is a full voice analogue synthesizer module with deep modulation options due to its multi-destination LFO and Envelope. From Bass to Lead sounds, to drums and drones, Telepathy has broad and versatile sound design capabilities. It has a Full Analogue path (Typhon VCO, 4-pole low pass / 2-pole high pass filters, analogue VCA) that is digitally controlled for more precision over its parameters, resulting in a warm, present and distinct Dreadbox sound.

With lots of useful and musical features integrated into a compact size (10hp), and its skiff friendly design, Telepathy is a great addition to small or large Eurorack systems.

Features:

1x Analogue Oscillator with saw, square, -1 oct square sub and noise, plus PW control for square, level for noise and waveshape
Automatic tuning for the oscillator and fine tune
Analogue 24db Resonant Low pass filter with Oscillator FM and Noise FM and 6db High pass filter

Notes: A classic all analogue saw VCO core with 3 switchable modes, ART, 1V/Oct, LFO and is recommended as the basic building block for ART systems. It is designed for patching analog polyphonic synths from discrete modules or multi-mono patches in ART mode. When using ART the ATX1 takes care of the tuning including accounting for temperature changes. In 1V/Oct mode the ATX1 runs as a standard old school modular VCO. LFO mode drops the frequency range and is great for patching vibrato to other ATX1s among other things. The ATX1 outputs variable waveshapes with manual or CV control. Classic FM, PWM and hard sync are provided. A dedicated Gate Out in ART mode manages the voice envelopes or any modulation synced to that voice. TipTop consider the ATX1 the best sounding analogue VCO they have ever created.

Notes: Cutting Room Floor V3 Eurorack Module

(Vintage Reel-to-Reel Tape, Echo, and Stutter)

The Cutting Room Floor was designed to emulate the sound and functionality of vintage reel-to-reel tape overdrive and echo. This eurorack module reaches into the 21st century with customized features that traverse the world of modulation and delay. Imagine an abandoned factory with a fluttering tape machine left on repeat.

The Cutting Room Floor provides beautifully marred saturated tape tone, and ethereal repeats in a streamlined 6hp interface. Other features include a freeze button that traps any tone while still playing and CV control for time.

Designed and assembled in Seattle, Washington. Includes a limited 1-year warranty, if registered within 30 days of purchase.

6hp, 43mm deep, 150ma current draw.

Notes: Sinc Pravus is the Goldilocks of a quad offset in 4HP. Whether your CV ranges are too high or too low, Sinc Pravus is just right.

Use the back-panel switch to configure Sinc Pravus to either ±5 or ±10 volts. To use Sinc Pravus as a DC-voltage generator, just leave the input unpatched.

Each of Sinc Pravus's four channels are controlled by a dedicated potentiometer with an LED for monitoring signal outputs. The input jacks are normalled from top to bottom so it can offset the same signal by different amounts or simply act as a mult.

Sinc Pravus is a workhorse in 4 HP.

Notes: Another update for WMD's clever dual VCA, this time a little bigger to give more control. Digital control of CV and attenuation gives lots of creative options. Third time's a charm.

Supplier's Notes:
WMD have done several designs of this circuit over the years, the first one had no knobs, the second was too small, the MKIII is finally how this circuit should be packaged. This module does some really cool stuff and is super useful in any system.

The Digital VCA lets signal through like a normal VCA, but the CV and attenuation level is controlled digitally. This lets us do things like wait until there is a zero crossing to change the amplitude, resulting in clickless amplitude changes.

The Trigger mode causes the VCA to only update when a trigger is received. The addition of a noise circuit for each side let us do a very quick and easy sample and hold that never droops. With no input, 5V is normaled to the attenuator, so you get a 0-5V sample and hold. In Bipolar mode, you can get -5 to +5V.

Both sides have bipolar VCA mode (polarizer), which lets them invert the signal when negative CV comes in. Also known as ring modulation. With the zero crossing detector, this can produce some super wild wave shapes.

Notes: 8 channels of audio or modulation over ethernet. There are two modules and a 3' CAT7e cable to connect them together. There are 8 total channels that are unbuffered and bi-directional. The primary usage is to connect two cases or just send a bundle of signals from one part of your larger case to another. You also get the option of buffering up to four channels on each side. This gives you a local copy of the signal and sends buffered copy to the other module, saving you from having to use a MULT to keep a local copy.

Some notes:

When one side of the Light Rail is in buffered mode, you cannot send signals from the opposite side on those 4 buffered channels (the other 4 channels can still be used in bi-directional mode)

If you are after a different longer/shorter cable, you will get the best performance with CAT7e as it offers the shielding, which is used for the ground.

While the cross channel bleed is minimal, you will notice some very minor cross talk between the channels.

Notes: Bleeding Hearts Eurorack Modular Device

(Random Sequencer, Rhythm Generator, Destroyer, and Filter)

The Bleeding Hearts is a device that starves, bit crushes, splatters, and filters audio sources like no other. Feeding a gate signal to the Bleeding Hearts enables a whole new world of strange and random analog-generated movement. Each position of the 8-step sequencer can bleed into each other and interact with the destruction effect, creating gated and filtered splatters, glitches, and crunches that move to the beat of your patch.

Designed and assembled in Seattle, Washington. Includes a limited 1-year warranty, if registered within 30 days of purchase.

Notes: The VCZIII voltage controlled oscillator modules are Feedback's latest creation and are based on the VCOs of one of the most revered analogue instruments, the famous British pin matrix synth released in 1969.

The VCZIII series VCO is a result of the collaboration of Feedback modules and CMS-LAB and is a modern re-creation of those temperamental, organic and beautiful sounding VCOs from 1969 but with enhancements and adaptations to the Eurorack needs of 21st century.

There are two type of VCOs, VCZIII A based on VCO1 with variable shape SINE & SAW waveforms, VCZIII B based on VCO2 & VCO3 with variable TRIANGLE & PULSE waveforms.

Also, each VCO comes in two versions, one with normal fine tune potentiometers and one with precision multiturn potentiometer.

Notes: Hi-hats are typically rich in complex, inharmonic frequencies that create a metallic, shimmering sound. Hi-hats rely heavily on noise components to create the "sizzle" effect. While analog circuits can generate white or colored noise using transistors or diodes, it's difficult to get the noise characteristics exactly right for hi-hats. Designing a noise source that consistently produces the correct quality and amount of noise can require fine-tuning and careful component selection. Hi-hats need a very quick attack and controlled decay to emulate the sharpness of a real cymbal. In analog circuits, achieving precise control over these fast transients is challenging.

Hatz v3 has an analog circuit including 2 types of noises; "Metals" generates stable, high-frequency square wave oscillations, which are essential for the metallic, bright tone characteristic of hi-hats. "Texture" generates a unique, digital form of noise that has a slightly "stepped" quality, adding a texture that's not as smooth as white noise but offers a desirable grit.

Independent envelopes for precise transient shaping, and a bandpass filter for frequency control contributes to a complex, high-quality hi-hat sound. This design approach provides flexibility, realism, and tonal richness that elevates the hi-hat beyond basic analog percussion.

Notes: Introducing the TOMS909, the warmth of the classic, all-analogue, punchy tom-toms from the TR-909 drum machine. The TOMS909 contains all three of the TR-909's original LOW, MID and HIGH tom-tom circuits adapted for use in the modular format. The module was designed to sound like a fresh machine coming off the assembly line back in the 80's. To add flavour to the beast, Tiptop have extended each tom's tuning range so it's easier to dial soft bass drums on the low end and high-pitched toms on the other.

The toms circuitry is made up of 9 triangle oscillators and a stack of filters, VCAs, and envelopes which, in total, took about half of the space on the original 909's circuit board. Utilizing the latest in electronic design technology, Tiptop have managed to squeeze this enormous circuit, consisting of more than 450 components, into an area only 16HP wide. It is a beautiful board with hundreds of tiny, shiny components: it's a little analogue jewel.

Each tom includes a trigger and accent input with accent level control, manual tune, voltage-control tune input with attenuator and independent audio out. In addition, a MIX out is available that sums all three toms together as well as access to the MIXZ MixBus on the back. On each gate input, Tiptop have designed a dual pulse-shaper circuit so you can trigger your TOMS909 with trigger/gate signals from sequencers or any other pulse/clock sources.

TR-909 is a Trademark of Roland Corp Japan

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

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

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

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

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

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

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

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

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

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

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

Notes: The uOSC is a super versatile oscillator module, that also can be controlled via IMDI.

It offers a variety of waveforms/sounds, depending on the chosen mode:

Sawtooth, can be changed to a detuned group of three sawtooth waves
Squarewave with adjustable pulsewidth
Triangle and true Sinewave
THREE different wavetables, each one with it's unique, smooth blend between 16 waveforms
The pitch can be controlled via 1V/octave CV or the brand new IMDI signal (see IMDI HEART for more info).

The waveform shape can be controlled via a separate CV and/or also with a MIDI controller via the IMDI-HEART module.

Additional to the normal audio output a suboctave output with a squarewave is provided, and a third output with the mix of the primary oscillator signal and the suboctave.

Quite a lot for such a tiny module, right?

Please note: These micro module needs a carrier, like the uBASE module. The cannot be mounted directly into an AE case.

Notes: The MASTER module is the base of an AE modular system if MIDI control has to be possible; it contains:

The voltage regulation (5V) for the power supply of the modules
A MIDI input (minijack; Breakout cable to DIN-5 socket is available separately); the MIDI channel can be selected between 1, 14, 15,16 or OMNI
In/out-sockets (3.5mm minijack) for audio out and/or interfacing with a Eurorack system
All bus signals (CV, GATE, CTRL, MIDI clock/start/stop) as patch sockets
The power supply is a 9V DC wall adapter (see here).


Note: The MASTER R5 is the latest revision of the MASTER module which is the core of most AE systems; what's new here is:

The bus signals CV, gate, ctrl CV, MIDI start/stop/clock can be connected with / removed from the bus individually with the microswitches

The TRS MIDI input now accepts both types of TRS-MIDI adapters

The mechanical design is changed to be compatible with the QUICKSWAP CASE.

Notes: Remote extension module that allows to connect 16 signals (audio, CV, gate or whatever) between large or spread-out cases.

To avoid bleeding, signals are isolated with a ground line between them (both in the ribbon cable and the printed circuit).

The bundle consists in two XT modules and two ribbon cables (1, 1.5 or 2 meters depending on the option selected).

This is a passive module, it does not draw any current.

5 HP

Notes: What does this do?

This is a sound generator module with 3 oscillators + noise generator. This module is a complete mini synthesizer that can easily produce snare drum sounds. A 'trigger' signal is patched in order to hit the snare drum. The bottom row contains an internal mixer where you mix in 2 shell generator oscillators, one thud oscillator, and a noise generator.

The Trigger input is level sensitive. Lower voltages will result in quiet snare sounds. You can use this to simulate accent.

The Filter on the 'Impact' signal path was carefully designed just for snare drum tone control. It sounds very nice. It will not self oscillate, but the Q control can go very high in frequency. It has a 12db High pass Filter and a 12db Band Pass Filter. There is CV control for the cutoff and CV control for the internal VCA.

An auxilary audio input has been added to the filter. You can mix external sounds.

The tone of this module is very hollow. It simulates wood like snare sounds.

What this module can not do:
-FM modulation of the internal vco's
-track 1V per octave
-increase the decay legnth of the vco's. 808 like.

This module will always remain in snare land. You can not make it sound like a lead synth. This is a good thing. No menu diving, and the snare is always ready.

History of the design:

The Asteroid Snare drum started out on bread board as a TR 606 snare drum. That design only contains one oscillator, a transistor based noise generator, and a 'clipper' brute vca. It is a nice efficient old design, but it is too simple and boring. I decided to add (2) of the original oscillators, and replaced the noise generator with a digital based noise generator to make sure all production units were alike. The snare drum still was missing fullness, so I designed an addition oscillator called 'thud'. The poor vca from the original design was removing all the additional harmonics, so that was replaced by a OTA based vca, and I added tonal controls to the IMPACT signal, and the THUD signal path.

A 12db analogue filter was recently added in the singal path of the Impact circuit. Audio input was also added, with a static internal HPF on this input. The Aux input will sound metal like by default.

All of this amounts to about 200+ smt parts. Far exceeding the original design.

Notes: Add-on for the Krait module.

Ewa was created as a lovely partner for the Krait module, a syncable 3-channel modulation source. Paired with Ewa, Krait will get new useful abilities, such as 3 freely routable cv inputs, endless encoder for smooth editing without value jumps, dedicated clock menu button and clock and reset outputs.

Each CV input can be used to record external cv source in Record mode. Beside that you can route any input to any parameter of the LFO and Random too. With Ewa now it is easy to modulate LFO rate or Random slew for example. CV inputs are bipolar and react to the signals between -5 +5 voltages.

Additionally a dedicated clock menu button and clock output can make Krait as a clock source for other modules in your system that need sync.

Notes: Module A-188-9 is a so-called high speed VCO that tracks perfectly to the 1V/oct scale in the frequency range of about 15kHz ... 500 kHz. The main application is the exact drive of BBD modules (A-188-1/2) to generate sounds realized by means of the so-called Karplus-Strong synthesis. But even in cooperation with other modules featuring high speed inputs (e.g. digital noise, delay, frequency divider) the A-188-9 makes sense. In principle the module is made of a precision audio VCO followed by a PLL (phase locked loop) unit that multiplies the frequency of the audio VCO by 32. Thus the module can be used also as an audio VCO as it features the standard waveforms sawtooth, triangle and rectangle with adjustable pulse width.

Controls:
Frq: frequency control (coarse)
CV: attenuator for the frequency control input CV
Fine: frequency control (fine), small control without knob
PW: pulsewidth control for the rectangle output of the audio VCO, in HSVCO mode this control has to be in the range marked "HSVO", small control without knob

Sockets:
1V: frequency control input 1V/oct scale
CV: frequency control input with attenuator CV
socket with rectangle symbol: rectangle output of the audio VCO, the pulse width of this output is adjusted by means of the control PW, output level ~ 7Vpp (~ -3.5V/+3.5V)
socket with sawtooth symbol: sawtooth output of the audio VCO, output level ~ 7Vpp (~ -3.5V ... +3.5V)
socket with triangle symbol: triangle output of the audio VCO, output level ~ 7Vpp (~ -3.5V ... +3.5V)
socket with inverted comb symbol: high speed VCO output, waveform rectangle, output level ~ 5Vpp (~ -2.5V/+2.5V)

Switches:
Range
upper position: audio VCO mode (frequency range of the audio VCO about 15 Hz to 6 kHz, the high speed output is not usable in this mode! )
lower position: High Speed VCO mode (frequency range of the high-speed output about 15 kHz ... 500 kHz, frequency range of the audio VCO about 500 Hz ... 15 kHz), in this mode the audio VCO and the high speed VCO can be used simultaneously

Slew
upper position: medium slew time
centre position: short slew time
lower position: long slew time
Technical Note regarding the Slew parameter:

Besides the audio VCO the module contains a so-called PLL circuit (Phase Locked Loop) and a 1:32 frequency divider. A slew limiter is part of the PLL. It defines how fast the frequency of the PLL follows the frequency of the VCO. The PLL cannot follow the VCO without any delay. Rather one has to find a compromise between the residual ripple of the PLL frequency and the frequency follow rate. That is the job of the slew limiter (works in principle like a glide or portamento unit). For this the module is equipped with a 3-position switch that is used to switch the slew time in 3 ranges. When mostly higher frequencies are used ((~ 100kHz ... 500 kHz) a short slew time can be chosen. When also lower frequencies are required (< 100kHz) a longer slew time may be used to reduce the residual frequency ripple. More details about the working principle of a PLL can be found in the information about module A-196. Module A-188-9 is in principle an A-196 combined with an audio VCO and a 1:32 frequency divider.

Notes: Simple but effective stuff from Vermona. Four transformer-isolated channels take a Eurorack-level signal each and output it at +6 dBu line level via XLR connections.

Supplier's notes:
Quad Output Module

The inputs accept audio signals with a maximum level of +/-10V. These are output via balanced and galvanically isolated XLR outputs. The output level is +6 dBu when using standard Eurorack modules.

The TRANSfourMER circuitry allows all signals in the modular system to be output without distortion - no more annoying gain staging between Eurorack and audio interface / mixing console.

Notes: Emulate the nostalgic sounds of old audio equipment with the 2hp Lo-Fi. Finding inspiration in quirks and happy accidents found in audio devices of the past, Lo-Fi can take any sound and give it the magic of tasteful degradation.
Lo-Fi carries two degradation modes: Analog and Digital. In the analogue mode, control the amount of wow and flutter for anything from subtle to dynamic pitch fluctuations, tickle the sonic spectrum with ASMR hiss and crackles, and warm up the coldest sounds with tape compression and saturation. In digital mode, dial in BitCrush amount, sample-rate reduction, and the wildest distortion in 2hp to cover your sound in digital crunch, or emulate blown out speakers.

With CV control over each function, and an ultra-crisp audio pass through, take your patch from hi-fi to lo-fi at a moment's notice. Get reel with the 2hp Lo-Fi!

Notes: Beatsi is Omni-Tone's love letter to modular drums! Inspired by classic modular drum synthesis which uses the fundamental building blocks, Beatsi's timbres were created using the same methods, only digitally. Beatsi is not a sample player or a physical modeller, and it's meant to be that way.

Beatsi's interface allows for control over individual piece Timbre, Pitch, Decay, and Level. The timbres are organized into 3 kits: an orange (acoustic) kit, a blue (low-fi) kit, and a green (alien) kit. Within these kits the timbres blend smoothly into one another allowing for seamless modulation. Beatsi has two CV modulation inputs which are assignable to any and all parameters with individual attenuversion. Beatsi may be small, but it packs a serious punch.

Technical specs:

- Module Size: 3U X 8HP X 25 mm Deep.
- Current Draw: 160mA (180mA peak)@ 12V, 10mA@ -12V.

Notes: What does this do?

This is a mini analogue synthesizer that produces snare drum sounds. Inspiration was taken from the 5U Cor Synth DR02 module. Only the flow chart was studied and used to create this BLM product. VCV Rack was also used to simulate and test the building blocks.

Most of the circuits contained in this product are from other blue lantern module designs.

Some of the building blocks:

-2 1V/Octave Triangle Core VCO's
-2 Sine Wave Shapers
-4 Envelope Generator
-White Noise Generator
-High Pass Filter
-Tone Filter
-2 VCA's
-Mixer

The goal of this module was to recreate some of the more exotic electronic snare sounds.

You're not getting another Roland 'TR' module with the Gimme Some Snare Drum. All the building blocks contain full analogue circuitry, like OTA chips, and Op-amps. No vintage transistor based (Bridge T Oscillator) circuits are used in this product.

The best description as to what the kind of snare drum sounds this module can produce is something comparable to:

an Electribe Korg ER-1, Simmons Snare Drum, and the Mattel Synsonics.

Notes: With the MORPHEUS digital filter module, Rossum are finally able to unleash the full power of the 14-pole Z0-Plane Filters that Dave invented for the E-mu Morpheus synthesizer.

The MORPHEUS Eurorack module includes over 280 filter configurations, which are called Cubes. Each Cube is composed of up to 8 complex filters that you can picture as being at the corners of a three dimensional cube (hence the name). Morpheus gives you the ability to smoothly interpolate between those 8 filters within the cube's three dimensional space.

Due to processor limitations back in the day, the original Morpheus was capable of real-time morphing in one dimension, but interpolation in the frequency and transform dimensions were set at note-on and remained static for the remainder of the note. But even with that limitation, Morpheus offered sonic capabilities that are unmatched to this day.

With the MORPHEUS filter module, you now have simultaneous real-time CV control of all three dimensions, for dynamic timbral effects unlike anything you've ever heard before. In stereo.

Like all Rossum Electro-Music digital modules, all parameters are available for adjustment with a single button press. No menu diving.
