You may have already tried this, but I would open the MGU file in BIAB. Then go to the Notation Screen and click on the melody track. Then click on the "#" button to bring up the MIDI event list and make sure the melody track is selected. Look through the event list and make sure there is no embedded patch change on the track (this can happen with an imported MIDI track, for example). Then delete the patch change. Look through the entire event list, as sometimes it can happen in multiple places. Go to the mixer and assign the instrument you want and see if the "piano" is gone.

Just a thought.

(I'm posting this from memory, so it may not be exactly those steps, but close).
