Having a Native Instruments S61 controller i make extensive use of Komplete Kontrol so that all my VST instruments load through it and therefore i can control them via the controller and also have the lightguide on the keyboard show correctly.
With 10.5 I had no issues jumping between tracks and the displays on the controller would change as different instruments were on each track. Now in 11 Cubase isn’t telling the controller that the track has changed and therefore i end up with controller showing instrument settings for a different track. I haven’t dug further yet but my template has a few hundred instrument tracks all using Komplete Kontrol that are disabled and I enable them on demand as I need the instrument.
I reopened my project back in 10.5 and it worked perfectly, so if this is a bug in 11 then it makes it pretty unworkable for me i rely on using disabled\enabled tracks and Komplete Kontrol.
