Arturia KeyStep NOT WORKING (with Behringer Model D)

[rakans]

When I first connected it with the Model D it worked fine. Afterwards i Wanted to connect it with the laptop (which means i switched the buttons in the back to sync with ableton) to use it with ableton.

after that i wanted to connect it again with the Behringer model D (MIDI live set/ No computer included) and switched the buttons to MIDI but now it is not working, what could be the problem?

Have you checked that the Keystep is transmitting on the same MIDI-channel that the Model-D is listening to ?

It's easy to change the MIDI-channel on the Keystep (also my mistake)
