Notes: If we're honest we don't really understand fractals. Something to do with maths, apparently. But that doesn't really matter because we do understand this sequencer module, which is ideal for randomly twisting and morphing sequences.

Supplier notes:
Bloom is a fractal sequencer capable of generating infinitely evolving melodies with a host of musical features.

At its core is a powerful 32 step sequencer with two independent channels and an intuitive interface. What makes the Bloom come alive are its fractal algorithms which can transform existing sequences into powerful melodies, or even generate new patterns altogether. The base sequence is known as the Trunk and can be programmed by hand, or automatically generated with the Mutate function. Once a Trunk sequence is in place, fractal transformations are only a knob turn away by using the Branch and path controls. Each new Branch adds a complete variation to the base sequence and Path determines its passage through the set of recursively generated sub-sequences, offering a unique take on the melody with each turn of the knob.

Bring your sequencing to life with Bloom.

Notes: Ornament & Crime for 1U Intellijel format

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

The apps currently available in Ornament & Crime:

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

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

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

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

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

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

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

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

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

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

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

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

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

Notes: Kermit is a 4-channel programmable supermodulator with morphing wavetable generator and internal modulation matrix. Four channels operate as LFOs, audio rate oscillators (with 1v/octave response on two channels), 1-shot envelopes, random voltage generators, or sample-and-holds, all responding to manual control, external control voltages, or synchronization to the module's master tap tempo clock. Designed for maximum patching power in small systems, Kermit carries an unmatched functionality-per-HP factor with an easily readable display that shows parameters in their real-world units.

The module has a 16-bit DAC to accurately render subtle changes of voltage at extremely low frequencies. The oscillator mode is best suited for bass frequencies, and the waveform "character" modes restrict the morph behavior or degenerate the audio to a minimum of 8 bits with limited horizontal resolution, like the Konami SCC chip used with the MSX computer. The tap tempo facility features an input jack and a manual button. The tempo is shown on the OLED display in BPM. The relevant units (hertz, seconds, volts, etc) or selected waveform of each channel are contextually shown on the display as the user programs the module.

List of operating modes per channel:

LFO (1 volt/octave)
LFO (with reset)
Tap tempo LFO
Audio oscillator
Audio oscillator (unison)
Code scan
1-shot envelope
Gated repeat envelope
Tap tempo envelope
Smooth random
Stepped random
Tap tempo stepped random
Sample-and-hold
Track-and-hold
Tap Tempo sample-and-hold

Three parameters on each channel can be modulated: frequency, amplitude, or waveform. Both external CV input and internal cross modulation are programmable with hotkeys. For example: assign the output of Channel B to morph the waveform of Channel A by holding the Channel B button while turning the Channel A Waveform knob. All channels have manual control of frequency (coarse and fine), phase, wave bank, waveform morph, and amplitude. Channels A and B have full controls, C and D have single knob controls with deep parameters accessible by hotkey combinations. Still deeper functions are accessible through the Mark III menu system.

Kermit has a microSD card slot for loading custom waveforms, like its big brother Piston Honda. The SD card accepts one .WAV file in WaveEdit format (free software editor) containing 64 waveforms, also compatible with several other Eurorack modules. When loaded into Kermit, the waveforms are organized into 8 banks of 8 waveforms each. Each oscillator can select any of the 8 banks, and the 8 constituent waves can be smoothly morphed from one to another.

The Mark III morphing preset manager is in full effect on Kermit. The discrete preset mode quickly and reliably recalls all parameters in response to triggers or CV, accessing the true power of the module as detailed, carefully programmed settings are effortlessly loaded and changed. The morphing mode causes delightfully unexpected variations of the basis preset.

Insert a master clock signal and you're ready to go. Kermit is a reliable provider of endless rhythmically coherent modulation voltages and a reasonably competent "voice module" providing most common synthesis functions on each channel with an internal modulation matrix.

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

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

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

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

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

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

A lot to unpack here. Six-channel multipurpose oscillator/noise source/modulation generator with quantisation, trigger generators and even more. Seriously powerful all-round digital goodness.

Supplier's Notes:
Mob of Emus is a powerful music and sound design tool that packs an enormous amount of creative power into an amazingly compact 16HP module.

Mob of Emus gives you six channels of oscillators, noise sources, cyclical and 1-shot modulators (including LFOs, envelopes, and various other shapes), sample and hold waveshapes, slow random modulators, triggers, rhythm patterns, and quantization (of both internal and external signals) in pretty much any combination (well, any combination of six channels, anyway).

In addition to being able to independently program the function of each individual channel, Mob of Emus' Hex Mode provides a macro control layer that allows you to control all of its channels simultaneously (while maintaining the relationships of each channel's independent programming).

What's more, Mob of Emus' "harmonic" control structure makes it extremely easy to combine its oscillators into rich additive timbres, to combine its LFOs into stacked harmonic low frequency modulation waves, and to create modulation sources and triggers with intricate polyrhythmic patterns.

With an external trigger input, six CV inputs that can operate in six different control modes, six independent outputs, and an assignable mix output, Mob of Emus can operate as the heart of an almost unlimited variety of patches. And its 8 real-time controls will give you immediate hands-on access to a channel's (or all six channels') key parameters, inviting (and rewarding) exploration and improvisation.

Mob of Emus features include:

Six channels that can function independently or can be further controlled by a Hex Mode macro layer that lets you control all six simultaneously. Channels can be:
Wide-range digital oscillators
Noise sources
Cyclical and 1-shot modulators (including LFOs, envelopes, and various other shapes)
Sample and hold waveshapes
Slow random modulators
Triggers
Rhythm patterns
Quantizers (of both internal and external(!) signals)
Six CV inputs that can function in six different control modes
Eight real-time controls for immediate access to key channel parameters
Six individual channel outputs and an assignable mix output
The ability to store and recall 12 user presets
And much more.

Mob of Emus is 16HP wide and 25mm deep.

Power requirements (max): 130mA +12V, 25mA -12V. Reverse polarity protected.

As of March 2021, there has been a been a small bug fix to the recent software update for Mob of Emus.

The update fixes a bug where holding the Channel Selector Buttons for a short time to select a single channel and deselect any others was not working correctly.

The update fixes a bug where some Hex Mode parameters were not ignored when Hex Mode was set to off.

The update introduces a feature allowing users to double-click and hold the Hex button to reset all Hex Mode parameters and set Hex Mode to on.

Rossum Electro-Music made a change to the behavior of the LEDS when using the utility 'Display Software Revision'

Notes: Quad random, highly controllable, quantized-voltage generator and generative CV sequencer

Gamut Repetitor is a four-channel random quantized voltage generator with looping, range, key, and scale settings. It features a built-in quantizer with 27 scales grouped across a selection of three CV-controllable switches, so it's easy and fun to generate patterns you'll love. The trigger outputs can simply pass through the input trigger or they can generate random triggers for more modular merrymaking.

Patching GR is as simple as sending in a trigger pattern and turning Length up. Then you can use the built-in quantizer, key, and range controls to change the way voltages are generated. Once you hear something you like, turn the Length down to a sequence length you like (up to 32) and loop away!

Automatic Backup

All settings are saved when the module is turned off.

Skippy then restarts directly with these same active settings. However, it is possible to revert to the default configuration at startup with the NEW function or even return to the "factory settings" by pressing buttons 2 and 4 simultaneously at startup.

New Patterns in JAZZY

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

New "polystep"

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

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

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

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

New TILES

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

New ROLL Function

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

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

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

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

New Proportional GATE

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

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

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

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

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

Description:

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

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: 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.
