I am trying to connect an M-Audio Oxygen 88 USB MIDI controller to a 4th Gen iPad but no sounds on key input.. I am new to the iPad and I am connecting the keyboard as follows:
Keyboard > powered USB hub > USB cable > lightning camera connection kit > 4th Gen ipad
The keyboard lights up normally just as it would if it was connected to a computer, but no sounds or change in graphics on the iPad.
(note: If I connect directly to the iPad, or disconnect the power from the hub I get an error about needing too much power). Do I need to set anything in GB on the iPad, or should it be straight forward from the start?
