XDJ-RX + 2 CDJ 400

Hej there,

A quick question, maybe someone has already some experience with this;

I'd like to try connecting my XDJ RX and 2 CDJ 400's (just the stuff I have laying around) to my Rekordbox, like a '4 channel setup' .. Is it possible?

In a perfect world (or in my mind) it would be awesome that I can sync the songs over the 3 devices via RB.

Before I start messing around with it I'd just like to know if it would be possible at all? And what would be the limitations?

Any info at all is usefull!

Thanks in advance,

RS
