Thanks, Joe.
The second one ("corrected") does indeed have the initial MIDI/ABC problem sorted out, and it also reflects my suggested correction (admittedly one person's opinion, but I doubt anyone would argue). It's perfect, as far as I'm concerned.
I don't know ABC, but I have the original article to look at and my ex-jazz bassist dot-readin' chops =)...and the first MIDI posted is most definitely not the one you'd want in the archive.
