When I open my songs, there is nothing showing but the bass clef, stave-like lines above that (empty), and the chords. No notes. When I do as one of the AI devices told me and click on the melody instrument in the mixer, all the notes reappear and the extraneous detritus disappears.

Hi Jerry,

This is normal. When you open your song, the tracks will be empty until they are generated, and each time you generate (by pressing Play) the tracks will by a little bit different. This is how Band-in-a-Box works. UNLESS you freeze your track(s). To freeze your track, you can click the "snowflake" icon in the Mixer.
