Arturia added the inverted preset keys. Where the B represents the current drawbar settings with percussion and Bb represents it without percussion. The other keys have different static presets. Which are not very exciting in my opinion. It would be a nice option to assign and save other drawbar settings to these keys. Maybe added to a preset or saved as a global preset (like it was on the original B3). That way, one will have direct access to some favorite drawbar settings while playing.
