Yamaha CS-80 Vintage Polyphonic Synthesizer SN 1380

via this auction

"This vintage Yamaha CS-80, considered one of the most famous synthesizers ever built, is a polyphonic analog synthesizer released in 1976. This unit is in great working conditions, esthetically, mechanically and electronically. The road case shows normal wear and tear (see pictures).

The CS-80 supports true 8-voice polyphony (with two independent synthesizer layers per voice) as well as a primitive (sound) settings memory based on a bank of micro-potentiometers (rather than the digital programmable presets the Prophet-5 would sport soon after - I have one of those for sale too!!), and exceptionally complete performer expression features, such as a layered keyboard that was both velocity-sensitive (like a piano's) and pressure-sensitive ("after-touch") but unlike most modern keyboards the aftertouch could be applied to individual voices rather than in common, and a ribbon controller allowing for polyphonic pitch-bends and glissandos. This is the synth that can surpass Moog`s original Taurus bass pedal, with its prodigious bass end. And its polyphonic as well, with the same electronics as two complete CS-60`s, coupled to a weighted 61 note keyboard with polyphonic aftertouch, and separate velocity plus aftertouch settings for each of its two channels. It has a Ring modulator which is really an Amplitude modulator, because it`s equipt with an lfo and a depth control, so that you can also create tremolo effects. The ring modulator has the unique possibility that an EG can vary the LFO speed. This can be heard on the Blade Runner soundtrack by Vangelis, in which CS-80 is featured prominently; the 1980 theme tune to BBC sci-fi show Doctor Who; as well as the composer's soundtrack for the film Chariots of Fire..."
