I think it's part of Quicktime, but I think it may be part of an OLD
Quicktime release. I have QT 10 on two Macs (one Snow Leopard, one Lion),
both with GarageBand and iTunes installed; when I tried to play a .MID in
QT, it had to go download QT _7_ in order to play. Neither of them appears
to have installed a virtual MIDI device, though I don't have a ton of
experience with MIDI devices on Mac, so I may be misspeaking there.
GarageBand appears to directly handle their software instruments.

Windows. :)
