There is a site called Yet Another Digital Tradition Page that has the tunes for an earlier edition of the database available in various formats, including GIF. Apparently, the best version of the tunes is the Postscript version, but I haven't figured out how to view that version - and I don't need to, since my Noteworthy Composer reads the Mudcat Digitrad midis just fine. Anyhow, the other site may be worth a peek.
