I'd like to see an HD version of Figure for the iPad, the same way there is an HD version of Rebirth.
A few suggestions for a possible Figure in HD for the iPad:
1. Full song mode, instead of just loops.
2. Audio copy to the pasteboard, so that you could easily use sounds created in Figure with other DAW apps if you wanted.
3. More sounds.
4. Master effects.
5. Different color schemes, to help differentiate it from the iPhone version.
