I've looked at a couple of Mummer's Dance MIDI's on the net, and the all sound alike. I guess one person recorded a MIDI, and others have been downloading it.

The person who made the original MIDI was careless. (S)he got a drone going, then didn't start the tune at the beginning of a measure. Then didn't check the result. MIDI took the sound quite literally and produced a mishmash of dotted notes and strange ties.

I have never been able to fix a recording like this with Noteworthy. I don't blame Noteworthy. How much can you ask for a small price?

Bigger programs might be able to fix this kind of problem, but I would like to hear from a person who has actually done it before I spent the money.
