I bought the "MIDI Output" item but it doesn't work with my iPad mini.

I bought the “midi output” item but it doesn’t work on my iPad mini 7. I can’t find garage band in output. When I connect irig, sound doesn’t appear in midi.

What do I need to do to make it work? I am interested in using midi guitar. Thank you very much.

If you dont see any activity in the user interface, most likely you didnt give it microphone permission (enable it in iOS settings / security).

GB will listen to any virtual midi port, so you only need to enable midi output in MG, or select the midi output patch.
