These iPad apps are ridiculous! I like how they're making them more ergonomic so you can use the effects more effectively instead of turning knobs that you can't touch. Is there anythign they're not going to think of with these things? They're almost beginning to look like that with the right programs and the right creative mind that these can actually be a ligitimate tool in your sets and become almost a multi-controller that can change from song to song as your set needs.
