Havent tried it yet, but...

Ill edit this review soon to report back on actual app usage, just wanted to correct a previous reviewer -- you can use it wired up to a computer, they demo it with the iConnect MIDI (only downside, does not apparently charge device) by a Calgary company, though apparently the Camera Connector Kit will work with standard MIDI-USB cables. YMMV, check Google or future reviews to be sure.
