Shortkey problem

How do I get rid of shortkeys assigned to the MIDI Keyboard? I was playing around on my keyboard the other day with Cubase 7.5 running in the background and now there seem to be several commands accidently assigned to certain keys (C#, D, A3) which is really annoying! I wasn’t even aware that you could assign shortkeys to the piano.
And they don’t show up in the shortkey list.


Open Devices > Device Setup. Select Generic Remote Device and set its Input to Not Connected. This is the place, where you can assign MIDI messages to the Cubase functions.

Thanks, Martin!
I was desperately looking in the list of key commands.
