Thank you for all this additional information, though some of has gone right over my head!

I am an absolute beginner with regards to midi. I asked about it because someone at the chromatic harmonica forum (where I have been posting links to my play-along videos) asked me if I could supply midi files, so he could adjust the tempo. So I think i just need basic, simple midi for that--a simple midi accompaniment.


I'm going to sneak in a non-midi question: How do you handle a "pause" , that is, an upper semi-circle with a dot inside it, above the staff line. Is there a way to make Band-in-a-Box pause?
