My 2 centimes...

In addition to my previous wishes for a more discriminating quantizer
similar to what Anton has suggested, and my spike and ripple module...

One synth that I have always lusted after was the RMI Harmonic
Synthesizer.

It had a keyboard and 2 oscillators, but what made it unique was that
for each oscillator
you had separate sliders for the FUNDAMENTAL and 16 OVERTONES!

I am not a great fan of sliders-I would prefer knobs.
2 ins 1 out. 17 potentiometers. It would probably fit into 20hp.

I think a single VCO with this capability for additive synthesis
would be
unique and highly marketable.

...and to coin a phrase: I'll take two!!!
