Hi, I'm running Traktor using only an external mixer with no controllers. When I load drum and bass tracks onto a deck the bpm will read approximately either 85 or 170. Now sometimes when I load the next track and try to auto sync it either plays twice as fast or half as slow as it should. I'm not exactly sure how the bmp is read but I imagine with something like jungle its not as consistent as with reading solid 4/4 beats. Any tips on how I can either correct or work around this problem? Thanks for any help.
