So far my posts have all been about getting your tracks ready for mixing but not actually mixing anything. This time you finally get to mix! Of course you'll still be doing prep-work throughout the mix, but you'll have fun doing it and it'll make your mixes sound great right out of the gate.
In my last post I covered my Traktor Settings so I wont repeat any of those. However, I will restate that I use a Kontrol S4 to play tracks, so my of my suggestions will be optimized that that layout and experience.
