WHAT'S THAT THING ?
The 4TOMS is a set of four percussive voice with a full stereo mixer. It can generate a lot of various drums, and even kick drum or rimshot.
But the module can go further:
- Bell like sounds with the CV controle.
- Gentle drums, or very dirty saturated sounds.

Each voice has four parameters :
Tune, Tone, Accent and Decay.
Tune, Accent and Decay are CV controlable.
The stereo mixer provides volume and pan for each voice.

Voices 1 & 3 have a lower pitch than 2 & 4.
Voices 1 & 2 are normalled, as voices 3 & 4.
It allows to build more complexe drums.

A CUT input forces the signal to zero. (as applying the hand on the Drum Skin to stop the sound)

A lot of options are available on the back:
Selection of the CV input (or adding more input)
All critical capacitors are through Holes, to allows easy modifications.
