IOS 7.1.1 problems with iRig MIDI?

Since updating my IOS to 7.1.1, I seem to have a problem sending midi out of the iPad, through iRig MIDI and into my Korg MS2000.

Is anyone else experiencing problems after upgrading to IOS 7.1.1?

I’m just about to downgrade back to IOS 7 to see if there are still problems.
