I don't know if any of you use MuseScore. It is a free music notation program. I use it all the time to create lead sheets with the melody line and chords. It is a great program and absolutely free.
Anyway I just learned today that you can send a song from MuseScore directly to BIAB as a music xml file. Very easy way to load the melody line of a song onto the track. This may not be news for some of you. Just thought I would share for any that might find it useful.
