Michael,

This looks like an issue with Quicktime:
- When I play your midi it in Windows 7's Media player the instrument 
changes are at the right time.
- When I convert it to a wave-file in Windows using Timidity++ the 
instrument changes at the right time
- When I play it using Noteworthy Composer Viewer 
(http://www.noteworthysoftware.com/nwc2/viewer.htm) the instrument 
changes are at the right time
- When I play it in Quicktime for Windows 7.7.1 (build 1680.42) the 
instrument changes a note too late
- When I play it in Quicktime Player (7.6.6 (build 1710)) for Mac OS X 
(10.7.3) the instrument changes a note too late.

If you ask me, I see a pattern there ;)

Hans
