I did figure out that theoretically you can right click on the "section" part of a bar and select a different style.
So i should be able to have it play a bossa style A section and then swing style B section
but it doesnt seem to work or I am not doing it right.
also I see how to make multistyles from exisitng styles in the manual but I am not doing that right either.
I must say the learning curve on BIAB is nuts. in the future PG Music really needs to focus on making it easier to use. it has enough features.
eventually I will figure out how to make it do bossa swing
thanks
