Detailed Description

The QuickTime Music version of MidiParser.

QuickTime Music is actually a superset of MIDI. It has its own custom instruments and supports more than 15 non-percussion channels. It also has custom control changes and a more advanced pitch bend (which we convert to GM pitch bend as best as possible). We then use the fallback GM instrument that each QuickTime instrument definition has to provide.

Furthermore, Apple's documentation on this is terrible. You know documentation is bad when it contradicts itself three times on the same subject (like about setting the GM instrument field to percussion).

This is as close to a proper QuickTime Music parser as we can currently implement using our MidiParser interface.
