VirtualDJ supports OneLibrary: Open, compatible, and evolving

VirtualDJ supports OneLibrary and now officially supports AlphaTheta’s OneLibrary, establishing formal software support within VirtualDJ for the OneLibrary format. OneLibrary launched in October 2025 alongside Algoriddim and Native Instruments, marking its public introduction in that month.

To use the feature you need a VirtualDJ version that supports OneLibrary, meaning users must run a VirtualDJ release that includes the OneLibrary export capability. VirtualDJ can export a music collection to a USB drive in OneLibrary format, with playlists, hot cues, and beatgrid data preserved on the exported USB so those items are carried across.

OneLibrary-formatted USBs are compatible with CDJ-3000X, CDJ-1500X, XDJ-AZ, XDJ-AN, Opus Quad, and Omnis Duo, all of which are AlphaTheta hardware models.

OneLibrary launched in October 2025 alongside Algoriddim and Native Instruments. OneLibrary is a rebrand of Device Library Plus, and Rekordbox already wrote to USB sticks with essentially the same idea. The specification is not published, and compatibility between different apps is not guaranteed. The development shifts focus to ownership of players and potential lock-in rather than removing it.

All compatible hardware is AlphaTheta hardware. A OneLibrary-formatted USB can be used on CDJ-3000X, CDJ-1500X, XDJ-AZ, XDJ-AN, Opus Quad, and Omnis Duo. Serato and Engine DJ remain outside OneLibrary compatibility.

VirtualDJ now officially supports AlphaTheta’s OneLibrary. VirtualDJ can export a collection to a USB drive in OneLibrary format with playlists, hot cues, and beatgrid data carried across. You need a VirtualDJ version that supports OneLibrary to use the feature. Traktor Pro 4 and Traktor Play were announced as OneLibrary partners on day one, and AlphaTheta’s compatibility page lists Traktor coming in the next few months.

“That’s why VirtualDJ has always prioritised openness and compatibility.”

The material notes that this integration enables cross-device use of OneLibrary-formatted USBs on compatible AlphaTheta hardware.

The provided material states that the OneLibrary specification is not published and that compatibility between different apps is not guaranteed. The material also reports that all compatible hardware is AlphaTheta hardware and that Serato and Engine DJ remain outside OneLibrary compatibility. The provided material presents these technical points as limitations on cross-application interoperability and on which players can read OneLibrary-formatted USBs.

The provided material describes OneLibrary as a rebrand of Device Library Plus and notes that Rekordbox already wrote to USB sticks, characterising that as essentially the same idea. The material reports that this technical approach centres on writing collections, playlists, hot cues, and beatgrid data to USB, and that applications need explicit support to produce OneLibrary-formatted USBs. The material states that a VirtualDJ version that supports OneLibrary is required to export in that format.
