The hip in November was a piece of cake, compared to this right-knee. I had a pain management prescription refill appointment this week - and they called me to tell me the doctor was going to be out of the office, and they rescheduled the appointment for FOUR DAYS past when I would run out of pain medicine. (that would be very very bad, as besides recovering from the knee operation, I still have 9 herniated discs in my back and neck, and some other stuff). So, I called them back, and they were able to squeeze me in to see a different doctor, only now I had to travel to a different physical office, which ended up meaning a 1/2 mile walk from the nearest metro stop to the office, and another 1/2 mile walk to get back to the metro to come home again. Ouch, ouch, ouch. My knee swelled way back up, and my flexibility went down the drain, so I now have to work even harder to get the bending and straightening back to where it needs to be - with still a long ways to go.
Sorry to all for the digression.
OK, in simple terms, midi file 0 is data in 1 track, and midi file format 1 is multiple tracks. I do not believe either of those formats has anything to do with the issues. I got some edited midi files back from swamptooth that I have to look at, but he I believe has the best handle on the problem. I will look into all of this some more tonight, after I get back from filling prescriptions.
