Hi Lauri,
There's an article here on using ShowKontrol with Arkaos Grand VJ with a CDJ-2000NXS2 setup. It uses the PRODJ LINK data to communicate between the players and ShowKontrol, which then sends data over to Arkaos. But it sounds like you're asking for something a little different... the DDJ-1000 works with rekordbox in performance mode, but neither of those elements sends PRODJ LINK data, so ShowKontrol won't function. Even if you added a DJM-900NXS/NXS2 into the mix, it wouldn't benefit you as there is still no network data being sent.
I don't know if the TC Supply crew has tested an XDJ-XZ with ShowKontrol yet, but I've reached out to them to ask about it.
