Sam, I'm fine with both comments above but I want to make absolutely sure I understand one thing you wrote. When you say, "use soley BIAB built-in melody", what exactly does that mean?

If you mean the demo songs supplied with the program, no, they are not yours to claim; they are copyrighted by PG Music. If you mean you want to make a song based on a melody from a popular song or even a recognizable hook, you should stay away from that too.

But if you mean, let BIAB generate the whole song (which it can do), or generate a new melody to chord changes (which it can do), or generate chords to a melody you wrote (which it can sort-of do), then you are OK to use the new song you made.
