Thanks to Dean and Ken for helping me get my VCS issue resolved. Ken, that
22pF cap was the culprit! Thanks for spotting that.
I noticed that the Exp/Lin switches don't have an effect unless the CV
pots are at something other than zero. Even with no external CV plugged in.
That looks to be correct according to the schematic.
Anyway, now I want another VCS! Great module!
Thanks again for taking the time to help a lost soul. :-)
