Well the CDJ400 is pretty bad, so it prolly has a much worse resolution that your mixtrack. I do not know if you can dumb it down that much.
A CDJ 2000 lets you set the resolution so it will be much more like your mixtrack.
But as CDJs are getting outdated quickly and you actually have a better setup with your mixtrack than with CDJs the whole matter is getting obsolete. Just learn to beatmatch and nudge the platter and you will be fine for future controllers and software easily.
(Yes compared to his CDJ400 you have BY FAR the better setup…)
