I'm interested in making some really basic circuit diy synth modules. Anyone have any favorite simple circuits? Nothing fancy - I mean stuff a non-EE like me can totally understand and breadboard! I want minimal!

2 parts count Vactrol VCF:


Sound samples:

Two Simple Filter with VTL5C3 Vactrol

Two Simple Filter with NSL-32 Vactrol

Just don't feed it negative voltages or anything above 5V.

Of course - the Lunetta Forum on E-M

And here's another source for Lunetta type circuits and simple 'stand-alone' circuits.
