Yamaha CS-30

The CS-30 is a large, knob infested, black analog synthesizer with traditional features. It is a 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 sketch pad, pattern or arpeggio effect. The CS-30 does not have any on-board effects, memory nor MIDI. Although the CS-30 is just a monophonic synth with a short 44 note keyboard it offers a lot of programming flexibility, and plenty of knobs. It's used by 808 State.

It was OK for light softer sounds but the oscillators and filter were weak and coupled with the sluggish ADSR generators the synth lacked real punch.
The best thing I could say about it was it looks good in the dark with the sequencer running.
