I went through the video and sliced and diced a bit... This is what I think you might have missed. ;)
I believe this mixer is gonna be shipped with it's very custom Kontrol Z2 tailored Traktor Scratch with two standard and two sample decks (not remix decks).
The four button sampler seems to be able to switch between A/C and B/D. It is layed out like one of the rows on the F1 Remix deck controller and I'm pretty sure it would work perfectly with the standard sampler decks.
Looking at the video the it seems like the text "Flux Mode" appears with green background over the track title when he trigger the loop button. Maybe it's a new stutter effect that they have now incorporated?
Two new effects are shown, but with this "M"-icon in front of the name. It looks like the one has NO parameters active when seelcted, so it might be a built in effect in the mixer??? The two new effects shown in the demo are Laser Slicer and Bass-o-matic.
There are more questions then answers, so I'm looking forward to more details from Native!
