Mainstage changed all patch tempo and key

Hi there

Is there anybody out there who help me figure out what mainstage has done here. I don't remember changing any preferences or anything like that which makes this wierd but in all my mainstage concerts all the tempos are faster than before and all keys have been put up by a semitone (roughly). I would say it must be a global setting thats been changed but I really cant figure it out. Any help would be much appreciated.

cheers

Joel
