About three times over the two minutes, end of the file I leave it playing for a little the hit 1 to bring the beats together so you can (hopefully) hear the difference but not the best tracks to demonstrate it.

Same track in both decks, doesn't happen for quite some time at the start but when it does hopefully it's easier to hear.
