Hello to the community, I hope you are doing well. My cubase pro version is 12.0.60, I recently got a Native Instruments Komplete Kontrol S88 mk3, when I record a track, it shows some MIDI data being recorded on the event itself. This is shown in screenshot number 1,
When I open the event, it shows that there is MIDI info for Sustain, Velocity and Poly Pressure,
You have to select an event (note) in the editor window in order to see the Poly Pressure values. In your screenshot the C-2 note (I think this is the default) is selected. Say you have played an A4. Find it, select it and if there are polyPressure messages they should appear in the dedicated frame.
