[sdiy] MS-50 VCF/VCA

[Aaron Lanterman]

The GX-1 diode ring filter was covered by a patent. I wonder if Korg paid 
Yamaha royalities or if they just ripped it?

Wait... there's something weird about the VCA though... the diode ring 
doesn't look right to me, it's like everything got swapped aorund????
