I'm using a KMI K-Board Pro 4 with the factory MPE settings (and have elaborated with different settings as well for aftertouch settings). Playing a chord and then add pressure to a single note affects all notes. If I hold a chord and then add a note with different velocities the chord notes raises in volume if velocity is high and vice versa. (As a side note I should add that this behaviour is also manifested with DD in the polyphonic aftertouch mode).
