Not the total number; the number of programs per bank is limited to
128 because the number has to fit in 7 bits.

That's correct.
While we're on the subject, I was under the impression that the first
number in the %%MIDI program specification was the bank number rather
than the channel, and that changing the channel was a separate %%MIDI
command? This is logical, since to specify the program you need to
specify the bank and the instrument number within that bank, but not
the channel. The way it's currently set up in BarFly, %%MIDI 2 3
means use the third instrument in bank 2. Since Quicktime instruments
are not really organised into banks you cound also write this as
%%MIDI program 1 130 (130 = 127 + 3). This is likely to cause problems
with external synths though.
