Synth: Yamaha CS30 Review by: Duncan of RMI (doi_oing@mail.bogo.co.uk) Summary: 2 oscillators, 2 filters, 2 VCA's, 3 envelope generators, ring modulator, 8-step analogue sequencer, "stereo" output, no midi, no patch memory, very difficult to make same noise twice, therefore not a tool for lightweights! You can control LFO with any of eg's, you can modulate oscillators with each other, with lfo and with eg's, you can use one osc/vcf/vca path with the keyboard and the other with the sequencer; you can use the keyboard to transpose the sequencer....Looks? When I took mine out with a Mellotron, the Yam. got more attention...In use, it's "where the hell did that noise come from?" I'd guess you'd be looking at in the region of £300-400 if you can find one. Years Made: 1977-1982? Polyphony: can make several noises at once Multitimbrality: see above MIDI: Note on/off: needs hz/v interface MIDI controllers (aftertouch, CC, etc): Sysex patch storage: polaroid camera Sysex parameter control: Other inputs/external control: CV/gate: yes-hz/volt&s-trig Clock: no Other CV: vcf Audio: yes, will trig also Proprietary (DCB, etc): no Programmer: no Outputs: 1,2 and 1+2 (mono) Patch storage: polaroid! Patch dumping (MIDI, tape, etc): no Voice architecture: Interface: Sequencer/arpeggiator: yes Keyboard/rack: 3ft long, 3oct kybd Known problems: heavy, but not as heavy as CS80 Accessories: Related synths/gear: Other CS series mono synths, CS5 and up. Version of CS30 without sequencer. Price range: £300-top value! Availability: limited Strengths: Unpredictable, will not make the same sound twice. This really is a strength in a world full of samplers and black boxes. Weaknesses: See above. Other comments: Hours of fun.
