[sdiy] Additive Synthesis questions

[David G. Dixon]

Aaron, I see on your "design project ideas" list that the Buchla 148
involves diode bridges in the feedback loops of opamps.  Is it doing
something like this odd-harmonic generator?

This is an RF circuit, and I'm not sure if the same thing is possible at
audio frequencies.  In any case, the inductors could be replaced with their
opamp-based equivalents.
