Synth of the Month:
Yamaha CS-80

The Yamaha CS-80 is a polyphonic analog synthesizer released in 1976.

It supports true 8-voice polyphony, with two independent synthesizer

It has exceptionally complete performer expression features, such as a layered keyboard that was both velocity-sensitive and pressure-sensitive 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

Production of the instrument ceased in 1980. Vying with the Sequential Circuits Prophet-5, and Oberheim OB-X polysynths, the CS-80 is regularly described as the pre-eminent polyphonic analog synthesizer, and commands amongst the highest prices of any polyphonic synthesizer.
