Sorry to gravedig this thread, but I've been looking all over for answers to the same question. I've got the right cables, though the camera connector kit isn't an official Apple one, and the iPad and piano still won't talk to each other.
I'm trying to connect an iPad 2 to a Casio Privia PX-150, with no joy. I'm trying to use the piano as a midi controller in Korg Module Le, but when I connect the cords I get either no response or an accessory not supported message.
Using the MIDI Wrench diagnostic app shows there is no MIDI input. What did you change to make it work for you? Anyone else have any ideas?
Thanks Joe. I've since shelled out £40 on a Yamaha Bluetooth midi connector, but the iPad 2 won't even see it when I try to connect to it. My phone can see it, but won't pair.
I don't know what to think about this any more. I suppose the iPad 2 is the problem...
