What software? It plays here. I seem to recall some software gets confused without beginning repeat signs. Add those and see what happens. L: 1/8 is a standard default and so I don’t think that is the issue.
Why I want it?
Good question, I do learn by ear, and use this as a reference only.
But what I like about the ability to play this code is the slow down function.
But the main reason is that I don’t want to be beaten by a bit of computer coding and software
Both this and your original play on Tunebook on my iPad and iPhone. I’m sure up to date versions of EasyABC will also play it. If removing the chords worked for you it is probably because the software wants a space between the closing quote mark and the next thing. It should not demand that, but might have at some point. I’d suggest an update of your software to avoid future problems.
