Allan,

I'm not sure what MIDI package your using.   I have Cakewalk.  The 
help in cakewalk explains it better (and in less words) than I can.  
Whatever package your using should have an equivalent "all notes off" 
command (whether they call in reset, or something else).  Here's the 
text from the cakewalk help...

"Handling Stuck Notes

Under MIDI, the events that turn notes on are separate from the 
events that stop notes from playing. Normally, when you stop 
playback, Cakewalk attempts to turn off all notes that are still 
playing. Depending on how your equipment is configured, it's possible 
for notes to get stuck in the "on" position. The Realtime-Reset 
command stops all notes from playing.

This may be insufficient for some older synthesizers.  If so, set 
PanicStrength=1 in the [WINCAKE] section of CAKEWALK.INI.  To do so, 
you may use Options-Initialization File.  Reset will send a note-off 
message for every note on every channel of every port.  This makes 
Reset much slower but will resolve the problem"
