Much thanks for all your replies.

My goal would be to use BIAB to play live instrumental music, possibly saving the end file on mp3s and pdfs and use that to play with instead of BIAB itself.

I would follow the melody along for a chorus or two then solo over the changes for a while, etc. Although I have been playing a long time, I have not developed improvisation skills to a great extent, so displaying or printing the scales along with the melody would help with improvisation.

From your replies, I see there is no easy way to do this, like purchasing "one" product and using it. Looks like there is going to be some work involved in getting everything ready; not that I mind a great deal, but it it going to take some time.

One other alternative I am considering is purchasing Hal Leonard Playalong books with CDs. I have a friend who does this and likes it, although he doesn't play live with them.

I agree that the Music Industry is really behind the curve on digital formats. It seems absurd to me; all this for me to play in a venue that is already paying for Music copyrights to be played there anyway.

Thanks again,
Dan
