Something I just came across today.  I have an Ableton Live 11 project which has several tracks using Kontakt 7 libraries and one track using a Komplete Kontrol 2.8 track.  The Komplete Kontrol track inteacts and behaves normally with my Komplete S49 keyboard in terms of menu and light indicator interactions until I select one of the Kontakt 7 implementations in the project.  From that point on the keyboard seems to be completely detached from keyboard indicators and interactions even if I reselect the Komplete Kontrol library in the same way as if I were interacting with a standard Kontakt 7 track.  Is this a known bug?
