I have it – got it on the release day in Germany – even took a 100km ride to see this baby in the shop.
Same here, working with the Traktor Pro 2.6.6 without problems.
Its looking pretty bad (took a beating in all the time – plastic VS solid metal mixer > mixer wins) but anything is working great.
Hotcues – i have a Novation Launchpad for some extra button power.
Custom mapping inc. 8x hotcues (deck 1&2), 8x instant loop, kill EQ, moving grid on the fly and some other things. Thats all what is missing on the N4.
The integrated mixer and XLR outputs saved me more than once (clubmixer died… master down, plug the XLR in and you are ready to go).
But yeah this controller is not so popular, compared to other Numark controllers. But specially for mobile DJs this is a great and cheap unit, the only controller that is in the same price range and can offer all the features is the VMS4.1 – and its really heavy and the older version had many problems.
I will keep it, but really wanna upgrade.. Still waiting for the NS6 MkII – that will be amazing.. Metal body, better soundcard and jogs and all the missing buttons & functions.
Numark is amazing, they have so much great hardware out there – from cheap units like Mixtrack and the M6 mixer to the amazing NS7 & NS7 MKII (damn expensive and really heavy.. but just amazing).
Maybe i will grab the NS7 MkII if i can found one used (the unit it built like a tank, so i have no fear of buying it second hand) with a case.
