I have been converting Dick Greenhaus's new file set to MIDI via abc and will have the complete set available in abc (about 4000 tunes with words). If anyone wants the full set in this form I would be happy to supply them (for politeness, after Dick releases the MIDI).

(I do a batch conversion of SongWright to abc and use abc2midi to do a batch conversion of the abc to Midi. The process takes me a little over an hour for the 4000 files. In fact I have a some work to do on the synchronization of words with tune in the abc - it's handled slightly differently from Songwright - and when I do I'll create the MIDI files with text so you can use the Karaoke style Midi players to get words and tune played together, the way the DT player did on the PC speaker).
