1. it was not a synth with many voices but rather 16 mono-synths playing together under a wooden panel.
2. the Oscillators are the most important thing into the sound module itself: if you care about it you'll see that a CS has almost mathematical waveforms and it's crazy that yesteryear the engineers tried to cath with analog means what now they're trying to avoid with digital means!!
3. most important thing: the CVs !!!! most of the control voltages there were subject to soft-clipping phenomenon which plays a role ( listen how's the envelope of the ring modulator!! )
That's all, former or actual CS80 users will anything but not confirm what I'm saying .
