I have looked around and have read a few comments about porting garageband to iPad, but that seems pointless to me. What I would like is an app that turns the ipad into a touch interface for Garageband/Logic or even Final Cut and iMovie. I have wanted an audio interface with progamable sliders etc. for a while but can't justify the money. If you could sync the ipad via wifi and use it as a wireless remote and still have your mac do the heavy lifting for amp modeling and effects i would be all over it. My favorite app is remote, the ability to control my stereo from anywhere in the house makes smile everytime. I have seen the remote for garageband app something like that on steroids would be fun and useful. I hope someone is working on this already. I have worked with computer controlled machines using a touch screen and the advantage is having a way to control multiple, even unrelated, items from a centeral point without having a million buttons. You have the ones you need for what you are doing and all others are just a touch away. The potential for the iPad to be a wireless portable control device for almost anything is huge.
