Controlling your music with CDJs
Depending on hardware features, you will have direct access to many of the software functions like loops, key lock, or playlist browsing. Generally, you can expect to use your media player as you would with USB or CD. The built-in screens will also display track information in real-time.
If you have nested playlists within folders, you’ll need to access them via the library browser as it isn’t possible via the media player navigation.
