Feature

This is the audio path wired inside the synthesizer. Modulation CV are routed to modulation 
fader in a digital matrix. You will not be short of cable anymore, and you can even save your 
patch!

Module description

OSC 1, OSC 2, OSC 3 and OSC 4 

This are 4 sinusoidal oscillator. Each of this oscillators can be distorted thanks to 2 different 
modulations type and admit 3 different (selectable) modulation sources.
Each modulation fader can be assign to modulate the carrier using FM (Frequency 
Modulation), or AM (a custom Amplitude Modulation algorithm).
-The FM allow to modulate the carrier according to the modulator. This result in frequency 
mixing between the 2 oscillator.
-The AM modulation change the amplitude of the signal that is then wrapped in the 
waveshaper . This modulation create harmonics of the source without changing it’s 
fundamental frequency.

It is possible to create cross modulation (OSC 1 → OSC 2 and OSC 2 → OSC 1) for more 
complexity and impressible signal generation.
It is also possible to create auto-modulation (OSC 1 → OSC 1), but in this configuration the 
modulation algorithm (both AM or FM) have been tuned in order to create more interesting 
result.

LFO

This LFO offer a unique feature : you can adjust the shape of the CV using faders, not switch.
This allows to continuously change from a rising saw, to a triangle and then to a slop down. 
Or stop halfway between sinus and square.
The waveform (WF) fader control the shape of the transition. It change from a straight ramp
