I just recently purchased an iPad Air and the latest Traktor Kontrol S2 Mk2 with the intention of using it in my club performances. I have updated Mk2 firmware, and ensured that both the Air and the Traktor DJ software is up to date. Set up Drop Box and Sync as instructed. Switched iPad to flight mode and did a trial set of around an hour or so. All seemed to be working well so I decided to go live at the club the following evening. About two hours into the set everything crashed with the sound stuttering and both the Software and the Mk2 froze. Totally unresponsive touch screen and the level display on the Mk2 had frozen too. As You Can imagine, If the groaning and the clapping from the floor wasn’t enough of an embarrassment, the stripping down from the promoter just put the icing on the cake. Had to reset everything before I could finish the last half hour of my set. Please can anyone advise me on what I might be doing wrong. Many thanks, James Gray.
