OneLibrary

Take your music anywhere with OneLibrary. OneLibrary lets you create a portable djay library that works seamlessly across devices and platforms. This allows you to take your djay music collection, playlists, and library data with you and use them seamlessly across djay with supported CDJs, controllers, or other operating systems—including djay for iOS and Mac—so you can plug in and start mixing instantly.

OneLibrary stores all essential DJ metadata, including playlists, BPM, key, waveform data, cue points, and beatgrids. This ensures your music is ready to play instantly, with consistent track information and organization on any supported device.

What you can do with OneLibrary

• Transfer playlists between macOS, Windows, and iOS.
• Keep cue points, loops, beatgrids, and track order fully intact.
• Export your library for use on supported CDJ/XDJ/OPUS-QUAD hardware.
• Load existing USB libraries directly into djay.
