Which DJ Software Reads Cue Points Embedded in an MP3?
“Which DJ software reads cue points embedded in an MP3 file?”
Serato DJ is the only major DJ application that reads cue points and a beat grid directly from tags inside an MP3. rekordbox reads cues from a rekordbox XML file you import. Traktor, VirtualDJ, Engine DJ and djay keep cues in their own libraries and need them set in the app or brought in with a conversion tool.
How each application stores cues
| Software | Reads cues from the audio file? | How cues get in |
|---|---|---|
| Serato DJ Pro / Lite | Yes, from Serato tag frames in the file | Drag the MP3 in; cues and grid appear |
| rekordbox | No | Import a rekordbox XML, or set in-app |
| Traktor Pro | No | Set in-app, or convert from another library |
| VirtualDJ | No | Set in-app, or convert from another library |
| Engine DJ | No | Set in-app, or import a rekordbox library/XML |
| djay Pro | No | Set in-app |
Every one of these applications reads the standard tags: title, artist, BPM, key, genre, comment and cover art. Only the hot cues and the beat grid are proprietary.
Why cues are proprietary
Cue points are not part of the MP3 or ID3 standard. Serato chose to write its markers into custom frames inside the file so a crate travels with the music. Pioneer DJ chose a database on the USB stick and an XML format for exchange. Native Instruments and Atomix keep everything in their own collection files. Nobody agreed on a shared format, so each app only trusts its own.
What travels in every file
Even without proprietary cues, a well-tagged MP3 gives any DJ app a head start:
- BPM in the tempo tag, so the grid analysis starts from the right number.
- Key in the key tag and, in Club Ready Music's files, as both Camelot and Open Key in extra text tags.
- Comment listing the cue positions in minutes and seconds, so cues can be set by hand in a minute.
- Cover art, which most apps show on the deck.
What Club Ready Music writes
For tracks generated in the Studio with "rekordbox / Serato tags" on, the MP3 carries Serato cue markers (intro end in red, first drop in orange, outro start in blue, plus a vocal-in cue when the model reports one) and a Serato beat grid anchored on the first beat at the track's BPM. The DJ pack download adds a rekordbox XML for the same cues, a plain-text cue sheet for Traktor and VirtualDJ users, the WAV and the cover.
For DJ edits of uploaded songs, the MP3 carries title, artist, BPM and a comment listing the intro-end and outro-start times. The player on the edit page has Intro, Drop in and Outro buttons so you can hear the positions before you set them in your software.
Moving cues between applications
Third-party converters can translate one library's cues to another's, including rekordbox to Traktor or Serato to Engine. They work from the application databases, not the audio files, so the usual path is: load into Serato or rekordbox first, then convert.
Frequently asked
Is there a universal cue point format?
No. Each DJ application stores cues in its own database or its own tag frames. Serato is the only major app that reads cues directly from the audio file; others need an import or a conversion tool.
What does Club Ready Music embed?
On generated tracks, Serato cue markers and a beat grid inside the MP3, plus a rekordbox XML in the DJ pack. BPM, key and a comment listing the cue times are standard tags every app reads.
