Your comments are very helpful.
I run my sets with BIAB playing the intro and then proceeds to play the backup for the Melody line of a tune. I am a Woodwind player and perform with Soprano, Tenor Sax, Clarinet and Flute. I then have BIAB auto-loop the middle section so that I can solo as long as I need. The auto-loop is setup by the way I start my songs by using the "Cntrl 2" key to start the song. This will start songs with the intro but auto-loop the middle part. During the last Solo I stop the loop by pressing "1" so that the next section comes in at the Head of the Song. I use the formula with vocalists as well and it works well.
