I have this problem with remix decks that do not save loops in their entirety. besides that the program freezes when I close it. It's kind of frustrating to work with remix deck and try to save something. I keep it by the track collection before closing the program but however you want some loops disappear. As it is possible that in the middle of 2020 and with so many years of experience these people will not be able to solve this. I already buy Virtual 2020 and I have it as my second choice for some day if these people do nothing for these problems. My advice, don't waste your time on Traktor 2. Solve the blessed problem with Traktor Pro 3.
