This is the "REASON" that I bought an iPad!!
Although I had read about users connecting their midi keyboard to the ipad via the usb camera kit, it was quite a surprise that it worked as well as it did with my my Yamaha portable grand; albeit midi input only. Midi sustain and note velocity was all captured in real time into garageband using the garageband instruments resulting in a 3 track (freestyle) composition.

Thanks for listening...
