   That sounds simple.  I'll keep it in mind when I get there.

   Sure.  This sounds like the program changes in the MIDI file weren't 
at time zero.  The code now assumes that if the PC doesn't happen at 
time zero that it has to leave it alone and preserve the timing of the 
original file.

   The manual "fix" would be to dig through the events in the event 
editor, delete the BS/PC there and enter it into the MIPP.  It's not 
easy.  (Perhaps we could handle the case of a BS/PC before any other 
events on a track?  Can't remember if I considered that and decided 
against it.  It does change what the MIDI file is asking for.)

   And if there are multiple BS/PCs on a track, all bets are off.  A 
track will be set for piano in the MIPP and start playing violin at some 
point.  This is what drove the new behavior.  Will was having trouble 
importing MIDI files filled with BS/PC's on each track with the old 
code.  Now it preserves the BS/PCs throughout a track (it used to mangle 
them) and sets the MIPP for what it finds at time zero.

   Heh.  All the time.

Of course, since Rosegarden can save its project files, settings should  be
saved to .rg and restored when file is loaded. But since midi files are not
project files, nothing should be changed on loading such files.
