Anyone use a USB Y cable to charge your iPad and use a Midi controller at the same time? Would this work? Couldn't I plug the power end into a powered hub or into the wall jack provided by Apple?
@MikeP - not possible as far as I know. Basically the CCK is a USB hub (a single port hub). To charge the iDevice you would need something that connects in between the iDevice and the CCK. This is what the existing interfaces ( that charge the iDevice) do, the charging functionality has to connect before the USB hub circuit.
@MikeP, Could you use the $69.99 IK Multimedia iRig PowerBridge to charge your iPad and send MIDI and audio to your controller? I'm unsure whether it works for non iRig MIDI devices, but here's its compatibility list:
iRig Mic HD
iRig MIDI 2
