Hmm... I was wondering about the circuits in the Henry book Build a
Better Synthesizer myself... so far, it's the only book I've found in my
library that seems to have fairly complete VCO, VCA, etc. schematics...
the only problem is that it uses the increasingly rare SSM and CEM chips
to build the synths. Also, compared to some of the circuits I've seen
online, the schematics seemed... complex, I guess. Lots of parts
(particularly for things like the Supercontroller, where it seems like
the seperate components could have been built a lot EASIER without the
out-of-print SM76477 noise chip from TI) 

Has anyone had much success with these circuits?
