Cubase interface with arturia KeyLab 61 mkII

I use Cubase 12 with a Arturia KeyLab 61 mkII. I cannot get Cubase (12.0.70) to map to the KeyLab 61. I have tried the automatic mapping using the MIDI Remote Manager and also tried manually adding the mapping manually, again using the MIDI remote manager. The drum pads appear to map a series of musical notes, and the mixer section will only map the sliders and the buttons, but again they will not interface with Cubase 12. I use Windows 11 Pro, Cubase 12, MIDIox, ASUS motherboard, AMD 5700, 64Gb of RAM. HELP!
