HI i'm tying to find a way to systematically analyze sensory dissonance. I found the "roughness" object on cnmat website but I can't get it to work. I'm new to max so any guidance or other places to look would be very helpful.
thanks.

looks like it uses fiddle so it needs max4.x or you would need to swap out fiddle for sigmund~ or pitch~ or whathaveyou. But really, what an awesome idea. Fantastic.
