"MSRP was initially $6,800. and later was raised to $7,100. and if you were lucky enough to get one at all you paid retail for it. (BTW, using an internet Inflation Calculator that works out to $23,461.28 in today's dollars... so these used CS80s should really be selling for in excess of $20,000. today.) It is hands down the best sounding and most inspiring keyboard out there. Period. Nothing else even comes close.
Fat analog sound with 16 oscillators. That's like eight mini-Moogs at the same time!! (if you use the third oscillator on the mini as a control oscillator for vibrato like most players do). Velocity and pressure sensitive keyboard. Amazing glissando and portamento effects. A phenomenal ring modulator which can also emulate an arpeggiator. A wah-wah effect switch with a jack in the back for a pedal. And has the pitch ribbon bar which creates whammy-bar type subtle vibrato or soaring 8-octave dive bomb effects. Includes three different owner's manuals (pdf files)...
The synthesizer comes as shown in the pictures... with the power cord, black tolex lid, a clear removable music stand and the two metal legs that clamp together. They are very strong as they support 242 pounds. There are four holes on the bottom of the synth for screwing the legs onto the synth but I don't have those. It is resting on the legs and that's worked fine for many years. There is one minor modification to the unit... a tiny hard to see toggle switch a few inches left of the keyboard which puts all 16 oscillators in unison."
