Melodi generates sequences based on the mood you set so you can create the sound you're searching for
Notes: Really nice approach to sequencing from Omni-Tone. The Melodi generates 'semi-random' patterns based on tunable parameters and probabilities. Dial in combinations of scales, pitch range, tempos and so on to create unique melodies.
Supplier's Notes:
Melodi generates sequences based on the mood you set so you can create the sound you're searching for- it can be tweaked to create anything from a powerful bassline to a sparkly melody.
Ships with version 2 of firmware
Improvements: Skip, tie, length are now LIVE knobs. Added a ping-pong trend line and a blues scale.
GENERATE
1. NEW - will prompt Melodi to generate a new sequence.
2. TRIGGER IN - accepts a trigger to prompt Melodi to generate a new sequence.
CYCLE
1. ON/OFF - determines if the sequence will loop or require retriggering.
2. TRIGGER - button and jack trigger the sequence to restart at the beginning.
TUNE
* While adjusting tunable parameters, the light bar will reflect the current selection. For continuous parameters the light bar shows amount from 0-100%, for quantized parameters the light bar shows steps.
1. SKIP (continuous) - sets the probability that a note will be skipped in a sequence.
2. PLUCK (continuous) - sets the length of the gate, from short plucks to gliding between notes (portamento).
3. TIE (continuous)- sets the probability that a note gets tied to the next (effectively making the note last two clock cycles).
4. TREND (continuous) - sets whether the sequence trends upwards or downwards in pitch.
5. SCALE (quantized) - select the quantization of the notes used in the sequence. Choose from perfect notes, pentatonic scale, diatonic scale, chromatic scale and completely unquantized.
6. RANGE (continuous) - sets the range of notes from 1 to 4 octaves (unquantized)
7. LENGTH (quantized) - select the number of notes to play in a sequence (from 1-16, or infinitely generating at the max position).
8. SPEED (continuous) - sets the tempo of the internal clock, between 20 and 2000 BPM.
OUT
1. GATE - outputs the gate of the notes in the sequence.
2. PITCH - outputs the pitch (in V/OCT) of the sequence.
CLOCK
1. SELECT - Melodi will generate internal clock signal if select switch is up, and will use external clock signal when down
2. IN - connect external clock signal
3. OUT - output clock signal

Rosci is a digital VCO that generates random waveforms to create unique, rich, and full sounds
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 :)

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
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.
Technical specs:
- Module Size: 3U X 14HP X 25 mm Deep.
- Current Draw: 120mA (170mA peak)@ 12V, 10mA@ -12V.

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.

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
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 SetonixSynth/Tidbit Audio Psychedelic Voltage Processor, or PVP, is a four-channel chaos module. It uses colour-changing LEDs to produce fluctuating voltages in response to the Channel input, with each channel normalized in series to create increasingly chaotic "taps" that can be used one after another for different variations.
Any positive voltage input such as unipolar LFOs, envelopes, stepped voltages, or simply the onboard normalized voltage patched to a channel input is reproduced approximately on each channel output, with the PVP inducing unpredictable fluctuations due to the variable current consumed by an LED circuit with a mind of its own.
Joey is a Eurorack module that generates random gate sequences
Notes: Random rhythm generator
Joey is a Eurorack module that generates random gate sequences. It is the offspring of Skippy (Kaona's polyrhythmic sequencer), without simply copying it: it's a very straightforward module that provides unexpected yet controllable sequences.
It offers three main modes:
Random
For random triggers controlled by an internal speed or an external clock.
Fractal
A unique algorithm sprinkled with 5% chaos, creating evolving and surprising patterns.
Euclid
Generates four different Euclidean patterns for complex and evolving rhythms.
Each mode has three adjustable parameters set via a clickable encoder: speed, a mode-specific parameter (probability, fractal root, or Euclidean pattern), and gate length. An external gate input can take over to synchronize speed. A PLAY/STOP button instantly suspends or restarts the gates.
