I'm running an iPad 3, OS 5.1, iRig Midi. When I plug in iRig, it lets me choose from 2 options in the settings drop down list for MIDI SOURCE and MIDI DESTINATION (1. iRig Midi, 2. Network Session 1). I know it's supposed to use iRig for both (or I'm assuming it does), but I've tried all 4 combinations of the drop down options. Using iRig for both drop downs, the iRig plug in is receiving data because the IN light is flashing, and the OUT light blinks when selecting a preset in AP, along with the FXII changing to the desired preset. There's been a few times the AP tempo light flashes, but typically it does nothing. For the first time, and twice today, when I switched to a saved preset in the AP, it DID register the FXII preset name on the AP display. I tried all kinds of combinations from re-launching the app, to launching the app THEN plugging in the iRig midi, etc. It all seems very intermittent, but the problem in my case is the iPad/AP not receiving the data properly. The app did crash on me once in the 30 min I was messing around with it. All of these symptoms regarding the problems with the MIDI IN data also occurred exactly the same with my iPad 2 running 5.1.
