I searched the forums for an answer on my question, but didn't find anything. Apologies upfront in case I still would be duplicating.
My situation: I currently have the DJM600, the efx500 and 4 x SL1200. After a long break from DJ-ing and seeing the Minus-guys toying around with traktor on 4 decks + Maschine, I'm picking up my hobby again. I meanwhile invested in some X1's + Maschine. I was able to get hold of a spare audio 6 from someone, but will go to an audio 10 for myself. Objective would be to have the 4 traktor decks routed to the 4 DJM600 channels, but that leaves me with the maschine that still needs to be hooked up.
Obviously, I would like to keep the 4 channels free for the 4 traktor decks, so I prefer not to route maschine via a phono-in to keep full flexibility. As far as I can see it the guys from Minus and other DJs, regardless if they use the Xone of DJM mixers, also only have 4 channels, so I'm wondering how they hook it up. Do they use the send/return for external efx? Mic-inputs? Or do they dedicate one channel and route both a traktor deck + Maschine through it?
So basically, the question comes back to: how do I hook up 4 traktor decks + Maschine to the DJM 600, while maximizing flexibility? (and while sticking to my current gear - shifting to the DJM900 is an option in the future if I really get into everything again, shifting to the DJM1000 is not preferred)
