- apps that would let me quickly capture song or instrumental ideas while on the go, either acoustically or via some kind of virtual keyboard/VI, and save them for later so I won't forget
- apps for beat creation or the like to produce beats or beds while not in the studio, which I could later import into my DAW or Recycle for slicing and import into e.g. Stylus RMX
- any type of new instruments/synths which use the multi touch interface in innovative ways, either for sound manipulation or riff/lick recording
- control surface or remote control apps to use in the studio
In other words, apps that work as useful tools for the professional composer/songwriter, not gee whiz stuff that's essentially useless and only serves to show off 'how cool' the iPad is...


If you have any favorite non music apps that you can't live without feel free to post about those as well.
iPhone apps that also work on the iPad are welcome, although I'm most interested in stuff that takes full advantage of the iPad's bigger display...
Thanks,
