Rekordbox

Sorry, the license that came with the CDJ-350 was for rekordbox 2, which required a license to operate even the basic core operations of music prep and exporting. As of rekordbox 3, the software was made free and available for use without a key. Version 4 added the "dj" plus-pack (also known as "Performance Mode"), and this is the same in version 5. Licenses are required to unlock the "dj" plus-pack, however licenses from version 2 are not compatible. Should you wish to use performance mode, you can unlock the 30 day free trial directly within the software, or purchase a license or subscription from rekordbox.com.
