The ABC is very badly screwed up. BarFly can't make any sense of it, and neither can I. You seem to be using the "P:" construct to indicate both division of the music into sections and into voices.

I can retranscribe it into something more portable if I can see the original - and not otherwise, it's all so nonstandard as to be unintelligible. Are the originals around somewhere public?

There is no earthly point in having separate PDF and MIDI archives when ABC can generate both.
