Splitting live audio

My background is DJing so I understand the important of switching tempos, trying out new mixes or tracks on the fly, phrasing and EQ-ing a mix etc. The problem is that when you have that itch to be spontaneous you have no idea hows its really going to sound until its cranking through the club speakers!



With all the software and hardware that’s out these day is it possible to play audio through the speakers and in your headphones skip ahead and program the mix all while the not interrupting the live audio?
