+1 on all above.
My first full Denon controller was the MC6000 and - as a mobile DJ - I loved it. Seperate mic channels with tone control and reverb, ducking and good POST control making it a true 4+2 channel mixer as well as a controller. What’s not to love, right?
It came (in Europe) with a full version of Traktor. Tried that for a year and a half. Not too happy with it. Lousy beat-gridding of non-Electronic music and way to cumbersome in settings and such, not to mention portability between various laptops.
Since Serato was still the picky one at the time, I moved to Mixvibes Cross. A move I have never regretted. I got rid of my 6000 awaiting the mk2, but instead ended up with a setup with two SC2900/X1600 mixer. Nice, but never felt it gave me what the controller could.
In a gear swap I ended up with a Pioneer DDJ-SX, knowing that it was just an interim solution. As soon as it came out I started putting away the money for the MCX and it’s an awesome piece of kit.
I am partial to the traditional lay-out and size of two/four players and a mixer though and the Prime really makes that work it seems with ALL the features you’d find on a controller with bonuses.
