Hi Mr Pronk,
Reading your list of problem i think that the issues that you have are not the same as mine, but i can be wrong.
Here is a more detailed explanation of the problem i,am having:
I use my keyboard by setting up a mackie control.
This was recommended by native instruments when setting up the komplete kontrol to work.
It doesn’t matter if i restart cubase with the keyboard on.
I just have to select the keyboard for the midi in ant midi out ant push the rest knob every time i start up cubase.
The connection will go from time to time in between using cubase. This will request me to reset the connection.
I think the official support list for midi devices is weak.
I just don’t get that for such a populair keyboard like the komplete kontrol official support is not added.
