A feature in streaming-enabled DJ software that caches licensed tracks locally so they stay playable without internet during a set.
An offline locker is a local cache within streaming-integrated DJ software (such as Rekordbox with Beatport Streaming or Beatsource) that stores a licensed copy of a track on the device. Once cached, the track plays back without a live internet connection, which is essential for club or festival use where Wi-Fi is unreliable.
Why it matters
Streaming tracks that are not cached depend on a stable connection at the venue; a network dropout mid-set can silence a track instantly. The offline locker removes that dependency for any track you have pre-loaded.
In practice
In the days before a gig, open your planned crates inside the streaming panel and cache every track you might play. Verify the download icon shows fully cached before leaving home.
