This is definitely not for the DJ's who mix from one record to another record and back. This is catering to the pros.
But it could be as horrible as it could be wonderful, just like sync.
I can see some techno and scratch DJ's use this to really push into "live remixing" and next level stuff, but I could also just as easily see inexperienced would-be artists syncing up a bunch of stems and creating a trainwreck like nothing before it.
