Hi A_R. Yes I think so, I'm using "B" for the intro and choruses and "A" for the verses. That had no impact on the way the bass guitar plays. it's still just plunking 1, ah 3, ah 1, ah 3...

There is a tilde (~) symbol in front of the bass instrument within the mixer. From the looks of things that is indication that the style is changing do to incompatibility.

My tempo is 130 and the style default is 140 so I'm not sure why that would be an issue.

Thanks for trying to help!
