Perfect sync does not work on all songs on the Djay Pro app. These songs can perfect sync fine in the Djay 2 app, so it is not the songs issue. I have taken a video here:
iPad Air 2 128GB (with 49.6GB available free space)
Djay 2 v 2.8.1
Djay Pro v 1.0.1
Watch Me (Whip, Nae Nae) (X-Mix Version) on Chartbusters 119
Trap Queen (X-Mix Urban Version) on Urban & Club 197
Other songs didn’t work as well while others did.
All my songs are run through Platinum Notes
