Hi Joshua,

Unfortunately, as far as I can tell, external MIDI devices are not  
supported through QuickTime on OS X.  (This was true at least for the  
first few versions of OS X, and I have not been able to find whether  
they fixed this or not in Tiger, and if so how to use it.)  Quicktime  
appears to only support substituting in alternate sound banks for use  
on the local machine.

I'll shoot off a quick email to the Apple list and see if the  
external devices are still unsupported.  If so, it means I'll have to  
create a MIDI Music Cue for playing back MIDI files to external devices.

Best,
Christopher
