The B4 Rotator is not a static setting when calling upon it to play back MIDI files.

It is controlled with either CC commands embedded in the MIDi file, or use of the spacebar, or modwheel, depending upon how you have the B4 software configured.

Try embedding modwheel commands of "all the way off -- zero" for one position of the Rotor switch, and "all the way on -- 127" for the other, Fast position.
