Released: 1977

MSRP: Y1,344,000($6900US)

Synopsis:

Expands the CS60 functionality by adding velocity and being duo-timbral (2 full signal paths). Architecture Class: Conventional (subtractive).

Ebay Description:

The Yamaha CS-80 is a 61 key (aftertouch and velocity sensitive), 8 voice polyphonic analog synthesizer, featuring a dual signal paths, an LFO (saw:down|up, sine, square, S/H, external waveforms), ring modulation, ribbon controller, and 26 presets (4 editable). Each signal path contains an oscillator (sine, saw and pulse waveforms), noise, resonant low and high pass filters, and dedicated filter (IAADSR) and amp (ADSR) envelopes.
