At the moment I can only confirm that wierdly exporting a midi file with 
a track which has a program change 122 will generate a file where the 
program change is missing. As a counter-example I tried putting a 
program change 113 and that works, the program change is correctly output.

To check this I also used a handy midicomp program [1] which will dump 
the contents of a midi file as text and confirming the program change 
was missing in the file where it had been set to 122.
