Keep !defined(MIDI_THREAD) branch compilable...
... The break was caused by ffa67d2 which split the base class AudioIoCallback out of AudioIO. This change only demotes some member declarations from AudioIO into AudioIoCallback, and changes the qualified names of function definitions. So now you can eliminate #define MIDI_THREAD in AudioIO.h and rebuild.
