I suppose the answer must also depend on what you start with - a sound file, a score, a wax cylinder, or whatever.

I see this is the post you referred to. It doesn't play for me on Android - midi files rarely do, even without the complication of OneDrive. It occurred to me you might have played it on a midi keyboard: you can generate ABC from a midi device - I've done it with EasyABC and I expect other programs can do it too.

You can create ABC by scanning sheet music - I've done that too. There was a thread on that few months back on c.net comparing different apps (the good ones are expensive).
