On the inspector yes, on the QC controller no. And the on/off does not work. The parameter changes even if it is off.
However this the same as in cubase 10. But it is a anything else regarding cubase and remote controllers, yet an other close but no cigar. For example where is the key-commands for this learn and on/off? And they can not be controlled by remote. Maybe it is wise to not being able to turn off QC from QC, but from other sources? Cubase is mouse-centric.
