Monophonic synth with extensive analog control and shaping. It has two oscillators with separate outputs, two voltage-controlled resonant filters, two voltage-controlled amplifiers and three envelopes. It also features a ring modulator, external audio triggering and a simple but useful 8-step sequencer for use as a patterner or arpeggiator or whatever-you-can-make-it-do effect! 44 note keyboard!
If an excellent source of bizzare electronic sounds is what you're after then we and Wikipedia are happy to agree that "...because of its signal routing flexibility, the CS30 is... an excellent source of bizarre electronic sounds."
Serviced prior to sale, but it has some quirks that were difficult to pin down. _Sold as-is: Needs a little time to warm up, has the usual amount of bleed and instability you'd expect of a 45+ year old instrument, VCOs are slightly detuned when both controlled by sequencer. Converted to 240 volts during previous service.
