I just purchased BIAB 2020 Ultra Pack. I entered chords and melody notes manually. I figured out how to play the melody using a BIAB midi track (an organ) but would like to have another instrument play the melody at the same time. How do I go about creating an empty 2nd melody track so I can experiment with other BIAB midi instruments playing at the same time as the organ? Are midi files my only option for playing melody? Without changing the style of the song itself can I experiment with different styles for the melody track(s) only instead of using midi?
