Yamaha CS-30

Yamaha CS-30 Image

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.

Yes, I can confirm that. The ring modulator is situated on the VCA2 section, just below the "YAMAHA" letters. See my page: http://212.242.106.33/~etcetera/public/instruments/CS-30/cs30page.htm for details, description and some weird sound samples.

Can someone verify for me that the CS-30 and CS-30L actually have a ring modulator? I've seen it mentioned online including here but from looking at photos of it I can't see where it might be located? I've also read that it uses the same filter as the CS-80, is there any truth in that? Thanks in advance.

Impractical on stage because of lack of memory, the number of knobs ready to ruin your patch at a slight accidental touch and it's very confusing signal flow.

Sounds mediocre when used mainstream but perfect for experimental synthesis.

Ability to modulate sounds via internal step sequencer and A/D input gives a lot of power.

Herman Gillis had one in his studio as well.

I just bought one, that's a wonderful instrument for researching analog textures that just modulars can do!!
