Hi Mo. Your file displayed and played in both ABCJ and Five Line Skink. Your post reignited my interest in ABC and I had a go at getting EasyABC to work on my new (secondhand) computer. Your file displayed ok in EasyABC but does not play. However that is no big deal because, so far, nothing plays in EasyABC. It's a midi problem on my PC.

I didn't have to edit your file in any way for it to display in all three programs and to play in the only two programs that do play files.

Your file is fine so it looks like the problem is in ABCExplorer. It might be something under 'Settings' or Options' or it might need uninstalling and re-installing.

Another option could be EasyABC. I have troubles with it because for Linux all you get is source code. For Windows there is a fully functioning .exe file with a free download that should work straight out of the box.
