iOS 7 is here, but it seems there are serious issues concerning audio. TRAKTOR DJ, along with many other audio apps, is experiencing performance and stability issues on iOS 7. Initial testing has also revealed general audio performance issues that can affect some Native Instruments hardware. If you use TRAKTOR DJ or audio apps, we recommend you don’t update just yet.
Please see this Knowledge Base article for more details.
Please also note that an iOS device cannot be downgraded to iOS 6 after being upgraded to iOS 7.
We’ll let you know as soon as these issues have been resolved.
