Hi Hogman,

Thanks for the additional information. As I see from the Mac BiaB user manual, the Bar Settings window is accessible via F5, OPTION+B or from the Edit > Bar Settings on the menu bar. There's also this handy, dandy tip:

Tip: If the F5 key does not perform the expected function in Band-in-a-Box, you will need to go to the Apple® System Preferences and uncheck the system setting in the Keyboard Shortcuts list.


Anyhow, the Mac Bar Settings window has a text entry box labeled "Relative Tempo Change" just below a text entry box labeled "Tempo Change". Unfortunately, the Mac user manual really doesn't provide much how to use information.

I know you discovered this information but I thought I'd provide it for other Mac users that may run across this thread.
