SDS 800 Modular ?

SDS 800 Modular ?

2012-03-02 by niamorizrut79

Hello Everybody, I'm a new member from France.
I've looked for a modificiation page on the SDS800 but unfortunatly it seems that there wasn't a lot of answer to the first question.

I also want to get the maximum of the cem fitted inside in order to get some cool musical possibilities.

Somebody made this, I've tried to contact him but I had no response yet, look at this

"Simmons SDS800 modifications (CEM3394 chip!)

-MIDI-to-trigger interface
-resonance
-waveform selection
-pulse width
-oscillator to filter fm
-second skin frequency control
-run generator to filter freq
-shorter min,longer max decays
-lower filter range
-negative filter envelopes
-more percussive envelopes (added a transistor to help charge cap)

modified sds800 mp3

UPDATE: added a bunch of CV ins and outs, run generator outs, etc. + 2 CV joysticks. "


My first attempt is to make the random generator affecting the filter, I dream of a semi modular simmons brain, so I'm about to put some cv in/out on over the filters and the oscillators.

Do you have any schematics of these mods ?

Thank so much for your help, 

All my very best from France
