Circuit Overview:
      Released with the Prophet 600 the first midi machine. Weighted 76 key keyboard and 8 2 osc/voice analog circuitry. 16 bit envelopes I read. A lot of control. More soon, one's on the way!

Service Tips:
     It's a prophet 600 to a great degree. The key movement may require spacers to keep the opto interruptor 'sheets' from dragging.


I have one spare. Not sure where to get these otherwise.

Lots of discrete electronic parts. Let me know if you need anything.The Curtiss chips are available where you can get them. Check my stock always here ALso for EARLY rev with SSM2040 they are hard to find, but here is a engineered SSM2040 replacement Module. ALSO The CEM3340 has been reproduced (Contact Cool Audio! ) and rumor Behringer also will make them again. When it rains it pours?
