Here is my two cents. BIAB can intrepret the key when new midi is input. Otherwise, it is "set and forget". You can use F5 to change the key in the middle of you song, but that only effects the notation Key Signature. You can also manually change chords, but neither of those actions will change the selection of scales BIAB uses over the chords based on changing the key center. In orther words, the I chord is always what is set in Key entry section of the GUI.

And by the way, who ever mentioned Scaler - is correct.
