@Marcelo > I think you have the situation confused a bit -- if you're needing to use the RB-DMX1, you have to use rekordbox in EXPORT mode, meaning you can't use Pro DJ Link; you have to connect via USB to control rekordbox in PERFORMANCE mode.
Unfortunately, neither the DJS-1000 nor rekordbox performance mode are currently configured to work together, regardless of the XDJ-XZ. Your only option at this time would be to use the XZ with rekordbox in PERFORMANCE mode and the DJS-1000 without any sync, or use the combo in EXPORT mode and not use the RB-DMX1.
