MIDI CC Filter in Cubasis?

I am using the latest Cubasis and have loaded AnimoogZ onto a track. The controller is a LaunchKey Mini connected to the iPad.
Now I wanted to assign a Midi CC button from the Launchkey in the synth. So I went into the settings until I found the menu and was able to activate a function. I realized that the two left buttons on the Launchkey do not send/receive anything. Ok, maybe broken? But … in the standalone version of AnimoogZ without Cubasis it works perfectly. Here in Synth the No. 29 & 76 are displayed when turning the knobs.
Now finally the question :grinning:
Is there any filter in Cubasis that filters out these two (or others)? Because it seems to work in Cubasis from no. 80 onwards.
