Songs getting out of sync while playing

Have there been updates to Djay Pro for Mac? Ever since release I’ve had problems with songs getting out of sync even if I use the sync function. Normally I match up BPMs and songs by ear and fine tuning but I feel like I have to fine tune matching up songs every like, 10 seconds. Please help.

There is an update for djay Pro (1.1). It didn’t change the “Sync” though.
It would be very helpful to know about the concerned track. We could use them to improve our syncing feature.
