Cubase Elements 11 control with Korg Triton Taktile

Hi There,

trying to control Elements 11 with Korg Triton Taktile fails, i.e. there is no movement of the controls E.g. in Halion Sonic when moving the sliders at the Keyboard.
I have implemented the Mackie Control, and selected Scene 2 Cubase at the Triton. I have chosen TR taktile DAW IN and OUT and unchecked the All MIDI IN on the MIDI setup page, however, Cubase only respond to the change of both wheels from the Triton.
Any idea what can be changed?
