when i have a blues in F 12 bar blues piece and then press the transpose to C it does not change the piece to C?




Boy or boy, that sounds strange. We do get all kinds of questions but this is one of the most basic features in BIAB.

When you use the drop down to change the key, it comes back and says "do you want to?" are your saying no to this?

Have you read the manual?
