Folks, I am confused about "bar to bar" regeneration.
I understand the concept BUT,
When I started using BIAB, a forum member mentioned this. I do not remember exact wording but it went something like this:
With any change in chords, shots, number of bars, music line can change in unexpected places. Meaning you change something in a bar 50, bar 3 can play totally different stuff than it was playing before that change. That is true.
Sometimes I feel that BIAB arrangement is like a live slippery snake, that I have to hold tight

Does this idea of Bar-to bar regeneration
preserves the rest of the bars Before/After regenerated region?
Thank you.
