The Externals that I mentioned (particularly HyperMidi) are pretty
sophisticated at creating and manipulating static MIDI files. They should
work well with MC on a PPC Mac - the problem is if you wish to do this cross
platform... MidiShare may do this for you, but I think it will be asking too
much unless you go for Java.

Java will do that for you as there are good QT API's for sound / MIDI.
