Reply to Disabling the Sync Command

So I am a complete noob when it comes to mapping. I one day would like to get into it but due to my lack of time I really can't. I was wondering if any of you mappers out there could explain how to disable the sync function that happens when u hit the second button on the top row of the mfps. I hardly ever use sync and some times when I try to shift decks by hitting shift + the second button on the top row, the songs syncs and destroys my mix. Can this be easily disabled? Thanks for any help ahead of time!
