A quick peek at the Addictive Keys online manual reveals that the "X Mod" parameter must be set by each user, either manually or by using the "Learn" command.

BB uses the standard MIDI Continuous Controller command of CC7 for Volume.

The pic in the manual shows the plugin set to CC11.

If that CC11 is AK's default setting, the BB Mixer or Vol spinner, sending CC7, won't address it.

Try setting AK up for CC7.
