[sdiy] Korg MS20 Pitch to Voltage

Ben Ward's excellent site has schematics:

http://korganalogue.net/korgms/service/ms20/m20s.html

I also recently put a page of Korg-related links together, mainly from the
perspective of the filters (and clones), but if you visit some of the links,
you might find other Korg stuff useful to you (like the X-911 which also had
a frequency-to-voltage circuit):
