-I would really use Engine DJ on my laptop to check songs together. I like 2 decks view but it is very limited, becuase as i see there i no way to modify song keys.
-Besides that it is handling douled BPM-s badly. Sometimes DNB songs analysed half speeded: 87 bpm instead of 174, which is just fine for me. However when i try two songs together it pitches 87pbm song + 100% to match… insane. Noone wants to double speed in real life… Rekordbox just leave as is, works perfect.
