The DS7 Drum Synce (DC860) is a little analog percussion synthesizer from the 80’s made by CORON. This drumsynth was dedicated 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 and 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 trig pulses or even gates. In this case the decay pot become a release pot.

There is lot’s of clones available e.g.:

• EugeneCarlo/coron-ds8-super-huevo-edition
• melka/Coron-DS8-Eagle
