Digital function generator

  • 3 operating mode: single shot (attack/decay), sustained (attack/sustain/release), looping (VC-LFO/VCDO).
  • 3 frequency ranges: low (20 minutes to 5 Hz), medium (0.05 Hz to 300 Hz), high (8 Hz to 10kHz).
  • Freeze gate input to stop the oscillator and hold its output.

A large palette of waveforms

  • Shape control with CV input – covering various combinations of linear, exponential, or sinusoidal segments.
  • Slope/asymmetry (A/D time ratio) control with CV input.
  • Smoothness control with CV input. From 0V to -5V, smoothes the waveform using a 2-pole digital filter, from 0V to +5V, adds bumps and kinks with a digital wavefolder.

Advanced features

  • Output level CV input (digital VCA).
  • Dual outputs: standard unipolar waveform, and "double-shot" waveform with a positive spike during the ascent and a negative spike during the descent. At audio rate, both of them have a different sound.
  • Accurate V/Oct tracking with straightforward calibration procedure.
  • Clock input to lock onto a multiple or fraction of a trigger sequence, or to generate harmonies directly from an audio signal (PLL mode).


  • All inputs: 100k impedance.
  • CV inputs: 12-bit, 1kHz for shape/slope/smoothness, 12-bit to 6kHz for FM, 12-bit 48kHz for amplitude.
  • CV Outputs: 16-bit, 48kHz.
  • Output levels: +/- 5V for the BI output, 0V to +8V for the other outputs.

Revisions and variants

An initial batch of 250 units was made by a dubious CM in the US, only a small fraction of which has been sold. The next batches were made in France at the end of 2014.


First batch made in France, labelled "v0.3":

  • Green PCB (originally black).


Hardware revision labelled "v4" with the following differences:

  • Thonkiconn jacks.
