[sdiy] CEM3340 question -- interpolating scanners (again)

[Tom Wiltshire]

This idea appears in John Bowen’s Solaris synth as the “rotors”. That’s a digital synth, so there’s no hardware crossfader, just 96KHz processing.

There’s a sound example too:

Specifically, what if each channel was a different waveform from the same VCO and   the scan rate were at an audio rate (perhaps 8 times higher than the VCO PLUS, say, 1 Hz)?  Each VCO waveform would be visited slightly faster than once per cycle in an evolving manner.  Wouldn’t this produce an “animated” output perhaps similar to my “Tone Wheel Animator”?
