I was wondering what experience you have with these
VCOs that use circuits similar to thyristors for capacitor
discharge. Thyristors being built from at least one
npn and one pnp transistor, like in Korg Polysix or
At the first glance this would be the most economic design
method for polyphonic stuff, as it has the least component count
by far!
I have not built one of these myself yet, so I'd like to know
what pitfalls are there to avoid.

Any thoughts?
