With power turned OFF, remove any connected USB memory or computer, and confirm that no discs are loaded. While simultaneously holding the TIME MODE/AUTO CUE button and RELOOP/EXIT buttons, set power to ON. Accessing your music “in the cloud”– DJing is slowly but surely catching up with the rest of the world with music moving to the cloud, and CDJs now work with cloud music, too. Using a feature called CloudDirectPlay and with a subscription to Pioneer DJ’s Rekordbox Pro software, you can have a music collection in Dropbox, which you can work on from any laptop or mobile device, and which is accessible to you from any networked, online CDJ set-up Talk to the club where you want to play, and get some practice time – Most clubs will be happy for you to pop in early on the night or even daytime in the week to get used to their set-up, so don’t be scared to ask The CDJ-400 allows you to play your MP3 collection off CD-R/RW discs as well as music from mass storage USB devices, such as USB keys, external hard drives and portable media devices.

Using your laptop as effectively a big “hard drive”– Using a function called “Link”, you can plug in your laptop running Rekordbox, and use the CDJs exactly as if you had plugged in a USB drive, accessing your laptop’s Rekordbox music library in exactly the same way. The two advantages to this are that it is a bigger screen/better keyboard for searching and displaying your music library than the screens on the CDJs, and that it means you don’t have to export to USB every time you want to update your playlist

So for this review I’ll be focusing on the Pioneer’s CD and MP3 playing capabilities.

Using the CDJs to control your laptop DJ software – Nowadays, a CDJ plus mixer set-up can be used like a massive controller, simply controlling your laptop software. With Rekordbox it is really easy (after all, Rekordbox is Pioneer DJ’s own software), but it also works with Serato, Traktor, Virtual DJ and djay Pro AI. If you really don’t want to “ditch the laptop” or change your workflow too much, but you feel silly insisting on being allowed to bring your DJ controller to club gigs, this could be the way for you
