You would set it up like this (this particular pic has a serato box but traktor box is the exact same) Serato is probably more expensive because you get free software updates for life. With traktor you have to pay for each major update (e.g. traktor 1 to traktor 2). @ Above comment. Scratch (timecode) is alot more cpu intensive than MIDI. That being said any decent computer should handle it (providing you set it all up correctly)
This. also what do you call chillout. I think the closest i have to that would be liquid dnb style shizz. I guess i could try do house as well. Only thing is 19th of august is a sunday, is the achual night on a sunday?
