Taking the sound portion of the signal generator out would be exactly what I'm looking for. I don't need to hear sine waves change to modulated other waves, got me plenty 'o synths for that :D Just having the ability to enter the equations (which I do not understand, because I'm neither a coder nor mathematician) would be fine by me. I like the pretty lights. I'll take a look at the javascript, and see if I can dissect anything that makes any sort of sense to me, but if you get to removing the sine wave generators first, I'll be keeping an eye on this page!
