[sdiy] Compact VCF

[Harry Bissell Jr]

No trip to the JH-720 site would be conplete without
a side-jaunt over to Martin Czech's site for the
"Mystery of the Korg-35 IC"

http://www.geocities.com/SoHo/Museum/4459/circuits/korg35.html

There is an example of how the original MS-20
circuit was actually done.
