Very cool! Thank you for the links, interruptor. I actually looked at that controller and thought about it, but I think I like the idea of sliders better than knobs. Although that video sure makes a great argument for knobs! Haha.
I got my computer today, I'm in the middle of installing software on it. Haven't ordered the controller or interface yet. I'll probably do that tomorrow.
You guys helped a lot. Thanks so much! I'll probably stick around with more questions and whatnot to learn techniques. I have a lot to learn!
