When you File, Open Special and load a Music XML file, there is a checkbox to load all tracks into the BIAB Melody track. What did you do there?

If you did load all into one track, try the green SEQ icon to see if you can separate out the tracks, then change the instruments.

Note: I didn't try this - going by memory since I'm not at a BIAB computer.
