iOS 8.0.2 loses connection and all MIDI if locked #14

If I lock my iPad (i.e. put it to sleep using the power button). After a short while, after awaking it, the MIDI interface is inoperable. The MIDI app does see the interface but send MIDI doesn't work at all.

It looks like the main change is: if (sMIDIClientRef) {

MIDIClientDispose(sMIDIClientRef);
sMIDIClientRef = NULL;
}

Then the sharedClient is released. Will try this and see what terrible things happen!

OK, ignore this. Yes, certain MIDI interfaces fail, but apparently only a few. M-Audio UNO is one. You can get a generic interface that works perfectly every time so I will mark this as a problem with only certain interfaces.
