DDJ SP1 no Computer??????

I use 3 x CDJ2000NXS2 and a DJM900NXS2 all networked and USB's organised with Rekordbox.

I am looking at buying a DDJ SP1 and was wondering if you have to have a computer/laptop to use this unit. There are hints out there hinting of such use but unable to find out for sure.

I would prefer to not use a computer if I don't have to.
