My MIDI foot controller and Presonus interface both have MIDI IN and MIDI OUT connections.
If I'm only sending MIDI messages from the controller to the iPad via the interface, is it necessary to connect both MIDI IN and MIDI OUT? There are no messages being sent back to the controller are there?
Couldn't I just connect ONE cable from MIDI OUT on the foot controller to MIDI IN on the interface?
Also some clarification... (Sorry, I know I've asked this elsewhere, but I need an answer today) does USB MIDI behave like 'normal' MIDI, in that it will still send messages to the app if the app is not In the foreground (the active app) of the iPad?
