KEY SYNC FEATURE WITH NO LAPTOP

Hello,

I would appreciate a solution to this as i trust it is not that big deal, i hope.

I am having a 2 XDJ-1000MK2 and RMX-500 and a DDJ-XP1 and i really wanted a key sync feature without using my laptop at all as my laptop sometimes crashes while live.

DDJ-XP1 has SEMITONE buttons but doesn't work on stand alone mode connected via USB to the XDJ-1000MK2

Is is possible to have this dream fulfilled?

Thanks
