I have a Native instruments S88 MIDI keyboard and I can't make it work with Music Maker 2016 (licensed) and also 2020 (trial).

I have setup "Komplete Kontrol 1" interface as MIDI input (the default midi Input interface that is working fine with Reaper and Magix Samplitude 2016) but no midi signal is entering Magix Music Maker, I have tried several other settings but now I am out of ideas. Can anyone suggests the good settings, or are the 2 products uncompatible ? Thanks in advance
