My (Jason) most recent setup for the quad ipad section of my drum kit. I added a new blinky toy over the weekend to control more electronic percussion sounds and vocal effects. Looking more and more like the Star Trek control center over there.
It can be a mind f**k getting around the whole thing in the moment with one hand, while playing drums with the other hand, but the dorky nerdy side of me loves the challenge of making the computer my biyatch!! Aww yeah.
