Almost certainly there will be something like an "export to PDF" or "save as JPEG" option in Noteworthy. If you can make that work, email the result to me and I'll put it on my site alongside my "40 familiar Scottish session tunes" file.

Bryan Creer (TheSnail here) has a utility which converts Noteworthy to ABC - by all accounts it's excellent, but again it needs DOS or Windows, which I don't have access to.

I think 40 tunes is the maximum such a file should have.
