I’ve created a MIDI file for you to test the Bank Select messages. You can get it from here:-

Import the file into Cubase, check that the inspector is showing the track outputting to your Nord and then hit play.
If the Nord is responding to Bank Select messages (and they are what you said above) then you should hear a scale being played on different instruments in different banks one after the other.
