General Info Links: Vintage Synth Explorer
A more complex 6 voice dual vco/voice subtractive analog synth similar in many ways to other CS series. But improved in the memory department having storage for 30 patches. And a handy dandy card reader!
I've never worked on one. Anyone?
I believe I should have any electronic part or keys for these save exact transformer, etc. Ask if you have need.
