If any one could drop some knowledge on how to connect all this stuff to make my MPC the master it would be greatly appreciated. please include cables types and anything that you think could help me out. I wanna conncect all the hardware together and then link it up to a mac. please help me out guys.

Do you have a dj mixer? You will need one to amplify the turntable. Basicly everything plugs into your onyx mixer then your mixer plugs into your monitors.

does everything hook in to the mixer by midi

no audio. Midi only carries data that tells your equipment what sounds to play. You plug your audio cables into the mixer.

so if i take the 4 outs on the back of my triton and connect it to the mixer thru audio cables, do i connect audio from my mpc to the mixer also? and audio from my proteus to my mixer?

Yes.

A tutorial to help with midi connections. Midi cables are also known as 5 pin DIN cables in Radio Shack and may be cheaper than the music stores.
