Hi Dj tecktools community, i have put my first dubstep mix so far on soundcloud and would very much appriciate your opinions / criticism so that i can improve. Thank you and enjoy here is the link : http://soundcloud.com/crowd-control-...-mix-september
(btw i used my traktor s4 for this mix and one of the effects buttons is giving up so there is a moment when the delay freeze isnt triggered at the right moment)
