[sdiy] Questions about Pulse Width Modulation circuits, VCF Cutoff Freq & Resonance controls

[Alwyn Lloyd]

I've done audio rate PWM on my nord modular...

It can make a very gritty sound, which i like.. similar to FM in some
ways.  or wouldn't it be more PM??

Eitherway  , great for nasty lead sounds when you want to attack your
audience...
