There must be some logic there somewhere.


Welcome to the forum. You may be getting confused by the multiple "chorus" markings. A BB "chorus" is one time through the whole song (excluding intro & ending). Some reading up should help.

Meantime, try this: set the chorus (button just to left of lowest tool bar) to 1 and make sure the basic layout has sufficient bars to accommodate the structure you want. Go back into the repeats menu and set it the way you want, making sure the "generate new bars" option is enabled. Now you can add back in multiple "choruses" if you want the whole shebang to repeat. Does that help?
