[comp.sys.mac.programmer] MIDI Manager Application messages

The MIDI message type bits in the Flags byte in a MIDI Manager message
are three bits that tell the message type.  Currently, only 000 (real
MIDI Message) and 001 (MIDI Manager message) are defined.  I'd like
the MIDI folks at Apple to consider defining another 002 or something,
as "Application-Exclusive Message".  The first four bytes of such a
message would be the clientID (signature, usually) of the application.

This woluld allow applications to send little messages like "Start Recording"
"Stop Recording", "I'll handle these next packets", "Wake up now!", etc. to
each other.  This would be great for companies making products meant to
run concurrently under Multifinder.

Of course, if your application doesn't own or recognize the signature
in the first four bytes of the message, it should ignore it.

On another note (ha), will the MIDI Manager be a stock part of System 7, or
will I still have to license it to distribute it?
