A very helpful addition to the thread. I'm having to type onehanded for a while so won't expand/expound much now. BiaB is a musical livesaver since I can't play keyboards for a while.
With a bit of study and experimentation, I learned how to access this BIAB 'reads ahead' feature and always get a programmed 'smooth transition' just like a PG Music demo. I don't know if my speculation is correct or not but I can say with absolute certainty, I get a smooth solo intro, solo ending and can correct bad chord changes flawlessly every time. I have not personally had a single issue since learning the method.
Is this method something you can share?
