Notes: The classical Eowave synth voice has a new skin matching with the new product line.

The Domino is an analogue all-in-one synth voice with saw/square wave oscillator, ladder type low pass filter, envelope and VCA - it is designed for pure beefiness and grunt in the low end department. It excels at basslines, acid, kicks and low throbbing drones.

The core of the module is a dual waveforms oscillator with saw and square. The pulse width of the square can be modulated with the PWM input.

The pitch knob over a range is of 1 octave, designed to be used primarily in lower ranges. The CV input control the oscillator pitch in v/oct but is also normalised to the f Mod input. When the f mod potentiometer is fully open, the filter can be controlled in v/oct. Since the filter as self-oscillation capabilities, you can also use it as an oscillator.

The decay envelope is controlling the filter cutoff and is normalized to the oscillator pitch input.

The Domino provides two envelopes control options with its gate>VCA and envelope>VCA switch, allowing you to choose between using a gate signal or the decay envelope to shape the VCA response.

The Mix knob enables blending between the saw and square waves. Connect external sound sources to the Mix 1 and Mix 2 inputs to replace the saw wave and square wave, respectively.

This module also provides the dry oscillator waveforms output as well as the envelope output.

Main features:
Fully analogue synth voice
Dual waveform oscillator with control over the pulse width
Ladder filter with v/oct tracking and self oscillation
VCA
Decay envelope responsive to the amplitude of the gate

Notes: In our project Orage Magnetique to recreate a sound spaciolab to recreate sounds from space , this quad multimode filter has been designed to simulate the action of magnetic fluctuations on the sound landscape. The effecs of ionisation variations are modified by the different filters cutoff frequencies and the way they are synced. The module Fluctuations magnetiques (magnetic fluctuation) is a module from the modular synthesizer Orage Magnetique. This quad mutimode filter combines 4 independent multi-mode filters with selectable low-pass, band-pass & hi-pass. Each filter can be synced to one another to build to a 48dB low-pass/hi-pass filter or 24dB band-pass. Each filter has an modulation input and an individual output to create stereo effects a well as quadriphonic textures. The filters A & B and C & D can be used in parallel mode or serial mode.

Notes: Great value from this versatile percussion module, built around a noise generator and four linked envelope generators, each with its own VCA. Generate hi-hats, envelopes, shape drums or create modulation sequences.

Supplier's Notes:
Ricochet is a compact, fully analogue module featuring four interconnected decay envelopes, each with its own VCA and an integrated noise generator.

The module's design is inspired by the way skipping stones bounce on the water, creating a versatile tool for crafting percussive sounds.

The exponential envelopes are specifically designed to generate dynamic percussive tones. The unique linking function connects the end of one envelope's decay to the trigger of the next, enabling the subsequent envelope to activate once the previous one ends. This innovative feature allows you to create ratcheted envelope.

A front-panel trimmer lets you adjust the threshold for triggering subsequent envelopes, while a rear header enables connecting two Ricochet modules together, or linking the last envelope to the first. This feature transform the Ricochet to a weird sequencer where the steps length depend of the decay times.

Since Ricochet is fully analogic, trig inputs are velocity-sensitive, responding to a standard gates but also allowing attenuation to modify the envelope's velocity (you can play with the dynamic of your sound by attenuating the trigg input. Ricochet is also perfect to play with drum pads).

Each VCA features a gain control that can be pushed to achieve subtle saturation.

All envelopes and VCAs have separate outputs, but there are also mixed audio and envelope outputs. When an individual output is connected, it is removed from the mix. The decay modulation inputs are normalized between each other.

Last but not least, an analogue noise generator is normalised to the first input, so you can use ricochet on it's own to create hi hat kind of sounds

Main features:

- Fully analogue design so everything is responsive to the amplitude
- Unique linked envelopes feature
- Compact 4 envelopes 4 VCAs module
- Linkable to a second ricochet or looping back the last envelope to the first one

Some applications:

- Envelope generator
- Drum shaper
- Hi-hat
- Clap envelope shaper( with short ratcheted envelopes)
- Envelope sequencer
- Trigg delay
- Burst generator

Technical details:

- Fully Analogue design
- 14hp
- Skiff friendly
- Reverse power protection

Notes: Six-voice (or three stereo channel) mixer in a small format, the Supamix takes a straightforward but highly effective approach. Swap functions allow for creative approaches to mutes, randomisation and sequencing.

Supplier's Notes:
A compact stereo line mixer created with live performance and space optimisation in mind. This 6-channel stereo mixer has a fully analogue audio path with 2 VCAs per channel controlled by fines tuned analogue envelopes to minimise mute clicks. It also embeds a unique mute swap function with 6 modes allowing you to automate muting.

Supamix is a compact stereo line mixer designed for live performances and space optimization.
This 6-channel stereo mixer features a fully analogue audio path with 2 VCAs per channel and finely
tuned analogue envelopes for vactrol-like muting control minimizing mute clicks.

Supamix also includes a unique mute swap function with six modes, offering versatile
mute automation possibilities.

The mixer is designed with a variety of input options to accommodate different needs while
being compact:

- Inputs 1/2 have manual pan controls for placing static sounds within the mix.
- Inputs 3/4 have CV pan controls to moving sound sources in the stereo field
- Inputs 5/6 are stereo, making it easy to mix modules with stereo outputs (right input is normalized to the left) to mix the growing catalogue of stereo modules.

A header on the back allow you to use the L output as a TRS stereo output. Another header is here to link the Supamix with the O phone/line module.

The Swap functions on the modules are both useful for transitioning between sound scenes or creative applications. To change the swap modes on Supamix, press the Shift button and one of the mutes. If you press the Swap button, it will activate the swap manually. The following are the swap modes available.

1 -> Scene change gate : Reverse the mutes states when a gate is high
2 -> Scene change trig : reverse the mutes state when trigged (or if the swap button is pushed)
3 -> Binary counter : CV input between 0 and 5v will correspond to a 6 bit binary counter. At 0v mutes will be all oo, 5v will be all open. And it will count as follow :100000 010000 110000.....
4 -> Randomizer: Trigg to randomize the mutes. You can change the probability of having the mutes on by using a trigger between 2 and 5v.
5 -> Sequencer: Trig to go one step further. It reverse the current step mute state.
6 -> State rotation: Rotate the mute state 0v there isn't rotation, 5v is a full cycle rotation. This shift the mutes state (last one goes to first one)

Main features:

Notes: The Swing module is simple, but an effective addition to analogue sequencers. Swing is a voltage-controlled clock delay with three modes, which can be used to provide step sequencers with a swing factor.

Swing features a clock and reset input to synchronize to an external clock, and four outputs that can be time delayed.

Notes: The successor to Eowave's Fluctuations Magnetiques module is an even more advanced quad analogue filter, designed for cross modulation, complex routing and self-oscillating fun.

Supplier's Notes:
The Tempete Magnetique is a fully analogue complex filter/synthesizer module.

It was that was created as an evolution of the "Fluctuations magnetiques".

More than a mk2, Eowave designed it to push you to play with one of the most interesting things in modular synthesis: to divert the primary usage of a module to create unexpected and new sounds (aka this is not only 4 filters)

Tempete Magnetique is deeply inspired by the classical filters design as well as West Coast synthesis complex oscillators.

At it's core, has 4 multi-mode 12db filters that can be chosen to be routed in series or parallel, which can be used independently or combined and even cross-modulated, controlled by CV or with an integrated envelope follower (which can be used as a dynamic responsive envelope) and even pinged.

The Tempete Magnetique was designed to have several levels of use. The individual level with the use of separate filters, perfect for quadraphonic processing of different sources (A B C D).

The pair sections which allows for more complex stereo effects or to generate synthesis voices (X, Y) and finally, the global level with a cross-modulation of filters.

The independent outputs have been designed to be fed back into their input, turning them into oscillators (not really precise one, but you can make synth voice kind of V/Oct tuned with their very own sound, due to the fully analogical design, these oscillators may have strange behaviours sometimes, but this instability will bring you the warmth of analogue gears).

The pairs sections, of course, can filter an incoming signal, but can be transformed to full synthesis voice, percussion engine (exited by the ping input and modulated with the envelope follower) and way more.

This filter allows for anything from gentle, subtle filtering to a storm where the undulations of your sound and their intensity create new types of textures.

Main features:

Four independents or linkable multi-modes 12 db filter
Envelope follower who can act as end decay envelope sensible to the velocity
Cross modulation engine who modulate both pair of filters
Ping input
Outputs with phase correction to be fed to inputs

Some applications:

Filtering (obviously), can be used for quadraphonic or stereo filtering
Weird synth voice
Waveshaper
LFOs/oscillators generator
Crossover
External rhythm following - auto filtering

Notes: TITAN modules are elements from the Titan Capsule. They are sound generators built to recreate the sound of Titan haze. These transistors made oscillators have a wide range and a very particular sound. 2 TITAN modules will create deep and vibrant basses.

With the knob « densite des brumes », the sound will be shaped through Titan's haze from deep basses to high pitches. The titan transistors generate a very particular sound with a base frequency of +/-15 semi-tones from 1Hz a 6kHz.

Switch -2>0 : multiplies the density of the haze by -2. This will have a direct impact on the sound and make it 2 octaves lower.

Mod2 0>10 is the amount of frequency modulation of mod2 input

Notes: A dual function generator also useable as a dual slew limiter with control on the attack and decay of the slew.

Volcan is a simple but efficient dual analogue function generator that serves multiple purposes, including as an oscillator, LFO, AD and ASR envelope generator, and slew limiter with independent control over rise and fall times. Its full analogue design ensure responsive performance and dynamic responsive inputs.

In trigger mode, Volcan operates as a unipolar generator, while in loop mode, it becomes bipolar. This flexibility allows for a wide range of modulation options and sound-shaping capabilities. The curve of each function can be adjusted using the curves pots providing a smooth transition from logarithmic to linear to exponential responses.

Volcan's entirely analogue design allows for the input of control voltages beyond the limits of the rise and fall sliders, enabling the creation of very slow or fast envelopes and LFOs. This capability makes it particularly suited for West Coast synthesis, where complex modulation and evolving textures are a key focus.

As a versatile utility module, Volcan is the perfect companion for exploring the rich sonic landscapes possible with analogue synthesis. Its multifaceted functionality enables you to shape and sculpt sounds with precision, giving you the tools to push the boundaries of modular synthesis.

Main features:

Compact 2 rise fall module
Independent slew limiter inputs
Fully analogue design so trigger inputs are responsive to the amplitude of the trigger

Some applications:
AD ASR Envelopes generator
Slew limiter with different slew on rise and fall
