Early draft schematics
A distortion effects pedal based off of FETs,
and they’re working on torturing op-amps in various twisted ways. 😉
Take Rene’s MS-20 and give it
voltage controlled resonance via FETs (shows just the modification)
Take Ray Wilson’s 4-pole lowpass
and make it highpass, by following the pattern of the Polyfusion
lowpass and highpass filters. (This is a single-student project, instead
of one of the dual-student projects, so I suggested he do it without the
CV resonance and just put in a pot to keep the project simpler.)
Take the filter part of the Buchla LPG
design, cascade it with an equivalent HP, add some distortion in front
for general mayhem. Aaron suggests
removing the Si halfwave distoring diode.
Take Rene’s MS-20 clone and use
some Waspish CMOS buffers instead of op amps.
(This requires some rearrangement
since the CMOS buffers are inverting.)
