I tested it through the beta but did my first show with 3.6 last night. All very stable but Ozone sounded fantastic and kept my levels bang on (ive never been great with my levels) but pattern player was just amazing to use. I used all 4 fx banks, controlled by a midi fighter twister (thanks @Stevan) and it was just so much fun. I also use it on a dedicated channel. Its just so easy to use and I dont have to stress about keeping everything in sync like when I do with external midi controlled gear.
Still so much that can be done to improve it though (see previous comments in the beta forum) but its the best thing to be added to Traktor in aaaaaages.
thanks :)
