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.

The official VSE rating of 3 out of 5 is way to low. This synth could well be the sound innovators preferred tool. It runs rings around most other monophonics.

This thing is a monster. Only thing it lacks is a self-oscillating filter... other than that, it can produce sounds other synths which aren't fully modular can only dream of without circuit bending (and ruining any sense of being a collectors item)
Highly, highly recommended! Possibly the most under-rated synth I've laid hands on. The people who say it's hard to use should go and buy themselves a digital, this thing is the [beep] .

Great analog wizzard. Has lovely sequencer (the CS30L doesnt have a sequencer but comes build in a flightcase and legs) Has many parameters and modulation options.
Many words have been said by users about the complex setup and routing but IMHO it is as simple as any other synth if you just take the time to understand it properly.

There were 2 versions of CS30. One had sequencer with selectable sequencer steps from 1 to 8. Another one had simple switch 6 or 8 steps.
