An 11-step, 4 Oscillator patch, after NoizeHack's video here:

Except i made mine irresponsibly complex. The fourth wave, the one responsible for most distortions and such, can be toggled off and on, as well as toggling between two types of summing modes. Each wave, when on square wave, has width adjustment.

Feedback is much appreciated so i can code this up to v 1.0.
