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.

As modular as u can come in a hardwired synths. Sound is spectacular! Most people that owned or tried this one don't understand its functions I think... Worth 5 star easy! And VS should update review, it's a embarrassing.

I own 2 of these synths and their hooked up with the connections on the back as one synth I also own a moog modular this pair have a sound all their own that places them ahead of the mono rolands I have also owned the roland SH series synths that were patched together but they too also have their own sound that at this time I wouldnt sell the cs's atthis time due to the uniqness of the sound produced

I think it's just crazy that these sell so cheap compared to synths like Roland SH7, Pro One, etc... The CS30 is a SERIOUSLY deep synthesizer with so much internal routing. It can make my modular weep. And it still does the "Lead" thing very well. Add to that the super flexible sequencer and you have a synth that kills. I bought mine for $900 years ago and would easily pay three times as much for one.

I've owned a CS-1 (basic) CS-5 (simple fun) CS-15 (funky phasing) and just recently heard a CS-30. WOW
Amazing possibilities on this one. the 15 isn't even half as cool as this. The sequencer is really clever and the routing allows for a lot of textures and routing allows for a lot of sound morphing.
