Thanks to all for their thoughts. I guess I don't care what program originates it, as long as I get it as a .mid. I would think that the input should match what is on the Allen site as to note durations, so that anyone accessing it will find easy word match with the Allen site's page image, but if a program alters the note values-- whatever!
We do need to name the files by the song numbering at the Allen site ot it will be a mess to organize.
