im using traktor pro and a denon dn mc6000 when i switch from deck A to be or c to d back and forth while mixing the bpms will switch and thro the whole mix out of sync.. can anyone shine some light with a solution to this problem

[Ashigari]

are you using sync or the tempo faders? if the faders are used you should map them to soft takeover, that way the pitch won't change untill you hit the current pitch of the deck
