For your consideration is a Yamaha CS-80. Produced for a limited time in the late 1970's, it has become one of the most sought-after synths for musicians of many genres. It supports true 8-voice polyphony with two independent synthesizer layers per voice (16 oscillators total) and has a velocity-sensitive and pressure-sensitive, 5-octave weighted-action keyboard. Each voice of its completely analog voice structure has a single VCO, high-pass and low-pass filters with resonance, and separate envelope generators for the VCF and VCA. It also has a ribbon controller which allows for polyphonic pitch-bends and glissandos.
