My iPhone music app wish: I believe that currently available iPhone apps support either 'midi' or 'audio' multitrack recording, but none support BOTH midi AND audio in one app. In addition, midi sound is very limited as it doesn't support a full GM/XG instrument set. I hope this eventually happens as this will then bring music production capabilities on the iPhone to a much higher level. I'm keeping my eyes glued to the iTunes Store for these music app features offered in the near future.
