[sdiy] Best AVAILABLE OTA for building new designs?

[Ben Bradley]

I was thinking of the Roland chip (BA662A/BA662B) that hasn't been
mentioned, and I came across this discussion that may be helpful. For
high-quality "real VCAS" there's the chips from THATCorp, but they're
of course quite expensive compared to OTAs.

Regarding speculation of using a large quantity, a Hammond organ where
each harmonic has its own ADSR (with keyboard scaling and such) could
be interesting, though it would be cheaper to do in software.
