This is a crude wavetable lookup distortion/waveshaper, similar in concept to Audio Damage's plugin Grind. Incoming audio is fed through the phase modulation input of a stopped wavetable oscillator in order to remap the amplitude of the input to that of the wavetable's. Or something like that. This implimentation doesn't work super well but I'm sure you can get some cool sounds out of it if you tried. Try loading some different wavetables.

I made a pretty simple wavetable lookup distortion thingy in FX Grid. It sounds okay but it's fun to experiment with. Maybe somebody can improve on it. Requires 3.3 beta minimum, of course.
