Is your keyboard broken? Are you aware that all these capital letters is shouting at others?
My CDJ-3000 connecting to rekordbox in Performance mode without any issues. Keep in mind that they are working with rekordbox 6 only. They are working as an unlock device for rekordbox 6.
With rekordbox 5 they don't work out of the box.
I have connected them with a USB cable. From the Source menu of the CDJ you need to select the control mode to connect them with rekordbox.
If this doesn't work for you, you should provide some details how you connected them and what OS and rekordbox version you're using.
