That's quite a good answer. Personally I would't go via midi because you'd lose the metadata and have to add it in afterwards. I'd just write a program to do it.

But why bother? As your first AI answer correctly says there are dozens of collections of folk tunes in ABC. I doubt if there's anything in the DT not in several such collections.
