Yamaha CS60Released in 1977
The CS60 is an 8-voice analog polysynth, and is a scaled-down version of the mighty CS80. Each voice is a single VCO with a sub-oscillator, and a resonant LP/HP filter with its own ADSR envelope. There are 12 presets, and one user program. A ribbon controller for pitch mods, assignable aftertouch from the keys, and a ring modulator are great features of this 61-note synth.
