Tony, I want to understand your question fully. I’m unsure what you mean when you say “follow the melody line”.

If you are asking if BIAB will play your melody with a RealTrack instrument’s sound, then no. But are you asking if BIAB can provide harmony to a MIDI melody you input by a MIDI keyboard or a guitar that outputs MIDI, then yes, BIAB can make an attempt.
