I just found out some more. When I run pmidi with a midi file while 
Wacky Wheels is running, I can hear both the midi file I am playing and 
Wacky Wheels, but now I can also hear more of the music from Wacky 
Wheels than I can hear when I do not play the midi file at the same 
time. It doesn't matter whether I start pmidi first or Wacky Wheels first.
It seems they are indeed messing with each other.

Thanks,
