acquired some new gear.

so i have a set up consisting of a traktor s4, machine, midi fighter classic, and a macbook pro. last week by pulling a few strings i was able to get some dj equipment for free from a friend of a friend which was a djm 400, denon DNS-1000 and all the cables for them so seeing that im a digital dj and i got some analog gear is there anything i can do with this stuff to add to my set up or did i waste my time trying to get it? :p

You could use the DNS (only 1 of them?) with your S4 if you upgrade to Traktor Scratch.

If you have 2 CD players you could practice mixing without the laptop and learn to rely more on your ears rather than on visual cues through Traktor.
