A mapping is important. And for the DDJ-400 the mapping is included in the software, and the controller is listed as Natively Supported. I have a DDJ-400. It works great with VDJ. I rarely use it with Rekordbox. Posted Wed 09 Jan 19 @ 4:00 pm. Groovindj PRO Infinity Member since 2007. The DDJ-400's buttons and knobs are arranged in the same way as those on our professional NXS2 set-up. Develop your skills using an interface similar to that of our club-standard player, and enhance your mixes with Sound Color FX and Beat FX featuring curves taken from our DJM-900NXS2 mixer. You'll soon feel comfortable performing in DJ booths.
