One thing you'll need to consider is that the Synthacon VCF response is
highly dependent on the transistors and diodes. I built two of these in
a single panel and discovered that with identical parts the response and
sound is still quite different. I did not match the diodes or
transistors (a few notes on how to do this would be helpful - hint to
the list). I treat these filters as different critters. When I do a
stereo patch, the results are not matched. I don't really mind this too
much. But if you are expecting parallel, matched response with a single
set of controls, it is not likely to work well without a lot of
tweaking. This VCF is not a precision instrument. And it's not
expected to be.
