Thanks, yes - I was just thinking of all those times I've had a
looping MIDI file playing, then slotted in another MIDI file to take
its place (for the next section of music), and found I had notes stuck
playing from the first MIDI cause they never got their NOTE-OFF
messages.

But I'm sure you're right - in fact can't remember the situation I
describe happening with something as self-contained as the Quicktime
player (never tried it using Javascript either).

more specifically, I should have said : a pair of data bytes following
a status byte..
