   That's likely just a side-effect of the size and complexity of the 
code.  Someone wrote some code to do this, then someone else came along 
and wrote some more code to do this, and so on.  Since it works in the 
majority of cases no one noticed the repetition.  Someone needs to go in 
there and clean it up.

   Only just a month or two ago, rg used to send out duplicate note-off 
events.  Same thing.

   It's to make sure the synths are in sync with the current sequence. 
If we don't do this, then selecting tracks and playing on a connected 
keyboard will have surprising results.

   There are no timing requirements for CC's and PC's in the MIDI spec 
(other than that PC's should be sent "immediately" after bank selects). 
  It's incumbent upon the receiver to handle anything that might be 
thrown at it.

Sorry I was so abrupt Ted - I really need to go and have a cup of coffee or
something before posting :o

I take your points on the others, but in this case, where do you draw the line?
When the MIDI spec was written program changes were just a ROM pointer change,
and couldn't possibly be less than a millisecond apart.

Still, we've improved the situation for Yoshimi even in this extreme case and
no doubt will improve it further.
