Usually when someone asks about this they want to create an exact cover of something. Biab is not good at that, it's designed to create backing tracks to practice or play along with, not create covers. For that, stay in Real Band. There, you can keep the elements of your midi file that have the song specific hooks and riffs you want but you can still add Biab tracks. As you've already found out, many time's the RT's are not suitable for this, use a good midi synth like the Ketron and midi tracks can approach the RT's in quality and you still have exact control over them. Many times just adding a background RT like a strumming guitar part or a partial RD part adds such an element of authenticity that you're fooled into thinking the whole thing is audio, not midi.
