Rekordbox 4 Decks 2x XDJ 1000MK2 + WEGO4

Hello from Hamburg, Germany,

Is following setup possible

Rekordbox 5 or 6

a) Deck 1+2 (or 3+4 or 2+3 or whatever) = XDJ 1000 MK2

b) Deck 3+4 WEGO4

at the same time, so that 4 decks can be accessed?

Last option would be Traktor, unfortunately.

Looking forward to reading from someone :-)

With best regards

Lawrence
