The heads up at Native Instruments have just introduced their version of the ipod nano to their ipod for those who found the Traktor S4, its predecessor, a bit too pricey at $899. So they made things a little more simpler for beat novices by trimming down some bulk and removing some buttons (WHY DID THEY FU*&$IN’ GET RID OF THE FILTER !! ! ! ! ! )
The Traktor S2 will sell for a few hundred dollars less ($599 street) and will still maintain the same S4 integral design that has won a multitude of DJs over to the digital controllerism lifestyle.
Being a technical man, smaller has its price, but it does lower the bar for spending for beginners. You can still muster up to 4 decks at a time but are limited to just 2 physical faders.
