Vst quick control for transport not working

Hallo i use my akaipro mpk mini 2 to trigger play/stop and going to next/previous marker. From Today it suddenly doesn’t work anymore with no apparent cause. When i open the quick control window and i choose “learn”, cubase recognizes the midi signal, but then the transport commands don’t work. (the flag is on “receive”), i’m getting mad!!! PLease help!!!

Hi,

Do you use Generic Remote Device to trigger the trigger play/stop and going to next/previous marker commands? How does it look like in the Generic Remote Device? Is the correct MIDI Input selected?
