Normal DJing, both Decks in Sync-Mode. Just create a Loop for Song 2 while Song 1 is playing. Now press Play on the Deck 2 => Get a big Glitch to Song 1 because DJayPro tries to tempo align Song 2.
Everyone can hear your glitch.
Solution: Do not use Songs with Intros, quiet passages or anything without a Transient at your start point, otherwise DJayPro is lost.
