Circuit Overview:
A subtractive analog synth, very similar to CS-80 with 1 osc/voice. Same voice architecture as CS-80 and CS-50. Lots of custom chips including key decoder, DAC and all analog building blocks. Independent HP and LP filters on each synth channel and "sine feedby" vca to allow mix of a sine wave that isn't filtered. No velocity sense and only a light sensor type aftertouch. Only other synth to have the fantastic pitch ribbon of the CS-80 though, along with one "memory". (which amounts to an extra set of miniature sliders for the 'non-global functions). Also has the great ring mod.
Service Tips:
Typical problems in CS series are power supply over voltages which blow tantalum capacitors and they short, or the caps just fail over the years. During this various chips may be taken out. I've seen LFO chip, VCA's and dac comparator fail so they might be most susceptable.
Parts:
I believe I should have any electronic part or keys for these save exact transformer, etc. Ask if you have need.
