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
http://www.gzifcak.net/eim/sds-800.shtml"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
