The Yamaha CS-80 is a polyphonic analog synthesizer released in 1976. It 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 micropotentiometers (rather than the digital programmable presets the Prophet-5 would sport soon after), 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 can be heard on the Blade Runner soundtrack by Vangelis, in which CS-80 is featured prominently, as well as the composer’s soundtrack for the film Chariots of Fire.
