A month ago I bought two second hand X1 MK2 in perfect condition, in their boxes and with the keys. I have Traktor updated to the latest version but it does not detect the two X1 MK2. It is as if they both do the same function. I have tried rapping it in a few ways and still no way to get the four channels for my XONE 92. Can you think of a way to activate the two x1 MK2 independently. I don't even get the "default setap" section where the two should appear. I am desperate.
