I was looking at the video in which Ean Golden explain his S2 demo video and noticed that he had on the sampler decks some new buttons which I can't find in my newly updated Traktor version (2.0.3).
On each sampler there is a Key, FX and Cue button. The play button is also changed to show what type of sample it is... In this case one shot.
Since Ean now is a NI insider I guess he's got the newest beta relese available and is working on that platform aswell. Either that or I've missed something! :(
