Hi Karen and another welcome to the forum . . . If I am duplicating an answer already posted please forgive me as I am too lazy to read all the responses above.

If you are looking for good midi string sections for your backings the pickings with BIAB are slim. But with that said I have quite a few "show tunes" on my playlist, including Memory from Cats and have received good responses from audiences where I have performed them. In fact I am putting the finishing touches on Last Night of the World from Miss Saigon as we speak. With all this said I guess the short answer is that as BIAB stands you will not get an exact copy of any backing track, especially the ones requiring string sections but you can arrange some very good backings to every song ever written.

Later,
