Just did a couple more research on the Stanton DJC.4, hmm it certainly has a lot more features than the S2 but does it have a sensitive jog wheel compared to the traktor? Also, is the integrated audio interface in the DJC. 4 comparable to the S2 in terms of sound quality? What about midi latencies and control responsiveness?
the s2 is going to be better for scratching if you're into that for sure.
but it only works with traktor as it is specifically made for traktor
The answer is easy.
An Input for emergencies
Recently sold my S2 as I've moved to CDJs.
Would highly recommend, does exactly what you want it to do with tight loop/effect integration.
Used mine for UK festivals during the summer, and i didn't exactly take care of it (left it out in the rain once!) but it held up well apart from some minor flaking of the paint on the buttons.
