This file has been updated to include MIDI 2.0 interfaces.
The MIDI 2.0 interfaces were developed for the classic 68K runtime.
Since then, Apple has created the PowerPC and CFM 68K runtimes.
Currently, the extra functions in MIDI 2.0 are not in InterfaceLib
and thus not callable from PowerPC and CFM 68K runtimes (you'll
get a linker error).

/*
MIDI data and messages are passed in MIDIPacket records (see below).
The first byte of every MIDIPacket contains a set of flags
bits 0-1 00 = new MIDIPacket, not continued
01 = begining of continued MIDIPacket
10 = end of continued MIDIPacket
11 = continuation
bits 2-3 reserved
bits 4-6 000 = packet contains MIDI data
001 = packet contains MIDI Manager message
bit 7 0 = MIDIPacket has valid stamp
1 = stamp with current clock
