What is it?

Hi, This is a unique, home made Eurorack version of the classic Coron DS-8 Drum Synth.

If you're looking for a better, improved version of the Coron DS-8, check the DM77. It has the same features, tracks 1V/octave, is easier to build and takes less HP: DM77 Module (Coron DS-8 successor)

It's 16 HP wide. 40 mm deep. 3U (Eurorack) high. Panel is Dark Grey transparent Acrylic, 3 mm thick. Text is LASER etched.

Euro 10 pin Power Connector (+12/-12 volts).

The schematic is derived from Marc Bareille version, with some modifications.

It has been modified to be powered by a Eurorack Bus plus some mods: It has an external sound input (VCA effect) and an Impact generator (Clic or Pop sound for more punch).

CV input is not 1V/Oct. It's simply higher voltage=higher pitch (linear). Trig Input (actually GATE input) is protected against reverse and high voltages (10 volts max).

Output is a bit weak, but that's a feature from the original design :)

Controls are Pitch, Sweep, Decay, Trig sensitivity, LFO rate, LFO mod, Ext Level, Noise Mix, Impact Tone, Impact Level and Volume.
