Thanks everyone for the replies, I’m starting to getting out of the confusion I was in.
Though, can I ask a further question:
In case I have 2 CDJ 2000’s and a DJM 800, how would I then need to set up the equipment in order to have HID control with Traktor. I’m asking this because CDJ 2000’s support HID but DJM 800 does not.
Thank you
