I imported an .xml file into BIAB. The file contains both chords and melody. I want to change the midi playback track (that contains the melody) to another midi instrument, but no matter what I select, the instrument remains the same. The name of the newly selected instrument appears in the track window, but the playback doesn't change.

I have other BIAB songs that allow me to easily change the midi instrument to whatever I want. Any ideas on how to fix?

Thanks
