Oldtimer:

Probably best to entire your question as a separate post.
That should get you the answer you need.

In the meantime, be sure to check the link in pwarren's post above, and read through the directions to separate out the melody track within BIAB if you haven't already done that.

Then click on the Lead Sheet button.
Then Opt.
Then Notation Options
Then under Guitar Chord Diagrams
you'll see a Tab check box. Try that.

If that's still not what you're after, as I said, re-post your question.
Good luck!
