NI has a huge population of house music, compare to scratch dj. I know the Z2 is very affordable, but I have not seen a Z2 user beside Dj Qbert Dj Shifty or DJ Craze. Battle DJs are great, but house DJ and EDM is been the money maker. I think it's time for a 4channel to be in the market, able to control remix deck and input all the NI hardware as well. Like Audio 4 but with mixer capable and remix control. I think this is something producer and house dj can really appreciate. An integrated 4 channel mixer audio interface/plugin maschine or other NI hardware. NI Z4
