Two VCOs, two mulitmode filters, LFO, a noise generator and more! The CS15 was an analog synthesizer produced from 1979-1982.
It is found in the 2nd generation of CS Control Synthesizers along with the CS5, CS10, CS15, CS30 and CS30L. Coming right after the iconic and more expensive CS80 (and CS60 and CS50) and right before the wood side panel models (CS15D, CS20M, CS40M and CS70M), the CS15 was an affordable, nice sounding and robustly built analog synth.
