Pioneer you really need to focus on improving the auto beat grids. For a person like me, I have a library of over 10k tracks. I refuse to go through every single track and have to reset the beatgridding manually. Traktor seems to have this figured out . Especially being that every effect, and auto loop, and even the slicer relies on a proper beat grid. As of right now, I cannot forsee myself spending $129 on this software until I see the next update. As of now 4.0 isn't cutting in in several instances.
