long time Traktor user here and traktor has not crashed on me over 10 years. This weekend it happened on a club, prime time :(. Loaded pre-stemmed track to a player and traktor just crashed to desktop. Music stopped, people screaming and me tried to turn into a pumpkin. Took time to start the program again and start the track. After that i am not sure when i am brave enough to try stems again. Hows Your experience with t4 and stems?
