Coron DS-8

In 2001, a friend gave me a ds-8 for repair (was just the 5V regulator that had blown out). As I wanted one for myself, I’ve reverse-engineered it and produced a copy of the pcbs as a pdf file called the AK47… In 2012, after a lot of people seemed interested in the electro-music forum, I got back to my old copy of the DS-8 and produced a schematic of it.

I made a pcb from the schematic for a friend’s birthday so it works. However :

  • The footswitch circuit (in grey in the schematic) doesn’t work. It wasn’t working in the original DS-8 and i never got it to work.
  • Noise balance pot was originally a log pot. I think it’s better to use a lin pot in this instance.
  • I’ve added a pushbutton switch to trigger it without a piezzo.
  • i’ve added a cv input. it’s a bit crude but does the job.

You’ll find both files below :
