serato doesn't anyway, we both know that.... but the whole stigma of sync buttons doesn't surround traditional equipment, regardless of weather you use something like an X1 in conjunction with cdjs and a mixer, you're still using traditional equipment. it's the insta-dj style midi controllers (S4, denon 6000, VCI100 etc) that get everyone all worked up, usually those who have learnt their craft on cdjs and TTs. I disagree with the whole mentality... music is music, no matter where it comes from. sync away my friends
