Building an Analog drum module

I just received everything I need to build my own Analog Drum Module:

Drum Synce Clone Parts

Someone managed to convince me that by doing this I will be a even cooler musician, so here I am...digging on resistors, diodes, wires and meaningless boards!

The module is a DS7 Drum Synce (DC860)and the smaller one is a simple Gate To Trigger Converter.

The DS7 Drum Synce (DC860) is a little analog percussion synthesizer from the 80's made by CORON. This drumsynth was dedicaced to drummers : the DS7 was fixed on the border of a drum to be played/triggered by hitting the drum.

The DS7 contain a VCO +VCA chain. The VCO is modulated by a cheesy LFO and a simple decay envelope trigged by the piezzo cell pulse. The cell work as a pressure/hit sensor. It can be replaced by a jack to be used with any kind of trigg pulses or even gates. In this case the "decay" pot become a "Release" pot ... The VCA is directly controled by the envelope. The LFO can drive the VCO from slow modulation to hi-speed to produce FM like sounds.


I needed some new analog raw meat for the distortion chain... let's see how long it takes to build it :)
