For us to assist, I think we will need to know a few more things from you:

Is this a Windows or Mac version of BIAB? It may also help to know the Build #, which you can find in the Help, About menu.

What is the brand and model of your MIDI controller?

What are you using as your MIDI Output Driver (tell us exactly all it says in Options, Preferences, MIDI Driver)?
