First 3 cue points missing - Onelibrary

[shmimel]

I formatted my flash drive for OneLibrary within Djay, synced all of my tracks over and then brought it to a CDJ-3000 running version 3.30. Everything worked perfectly, and I ejected my flash drive after a set and brought it home. Later, I plugged it into my iPad, only to discover that the first 3 cue points were missing from every single track! I would assume this is probably due to the buggy nature of the 3.30 update, but I thought I should share since it’s a pretty interesting and consistent bug.

On the left is the track in My Collection, on the right is the same track on my USB:

Thank you! This re-confirms the need to avoid using USBs on a CDJ-3000 with the 3.3 update.

IMPORTANT NOTICE: CDJ-3000 Firmware Version 3.30 – Temporary Suspension of Distribution

Please note that the latest CDJ-3000 firmware v3.30 contains a critical issue related to the new OneLibrary introduction. See here for more information.

Thanks for sharing @shmimel. I will pass this onto our engineering team for further review.

Hi @shmimel, sorry for the delayed reply. Unfortunately, our hardware team is not able to test or reproduce this since AlphaTheta pulled the Ver3.30 firmware. Can you please try downgrading to firmware Ver.3.20 as recommended by AlphaTheta to see if this solves the issue? Thanks!

[shmimel]

Tried it last night, and the cue point issue seems to have resolved itself, despite the CDJs still being on v3.30. Will keep this thread updated if other issues occur.

Great! Thanks for the follow up @shmimel

Many of the songs on my OneLibrary USB are missing the first cue point which is always at the very beginning of the track.

Sometimes DJAY also seems to put the downbeat on beat 3 when it should be on beat 1.

The songs I am exporting all have the first cue point…

Wondering why this is happening? Is it a bug with OneLibrary or is there something I can do to avoid this issue?

[Slak_Jaw]

Hi @rishi, I’ve merged your new topic with this existing one. Can you please upload some of the songs that you’re having this issue with?

[rishi]

Here’s the file for the pics I posteed above

Here’s another example…

Rekordbox: Cue point 1 is on the first beat and downbeat on beat 1

DJAY:
Cue point 1 is missing
Downbeat is on beat 3

NB: My issue has nothing to do with CDJ firmware. I export to USB OneLibrary from Rekordbox and plugin into my iPad running DJAY. Many (not all) of my songs seem to be missing the first cue point which is always on beat 1.

Thanks for the files and additional info @rishi. I’ve shared these with engineering.

Hi @rishi and @shmimel, does this only happen for MP3 files?

[rishi]

@Slak_Jaw I only use MP3 files, so I can’t compare against WAV/AIFF — but based on the behaviour I experienced, this looks like it could be a start-of-track cue edge case related to MP3 encoder delay and beatgrid anchoring, rather than the cue not being exported.

The cue definitely exists in Rekordbox and is placed on the first beat transient (snapped to the beatgrid by pressing CUE near beat 1). However, when exporting to OneLibrary USB and importing into djay on iPad, that first cue is sometimes missing, while later cues are intact.

My suspicion is that:

• Rekordbox stores this cue extremely close to time zero (e.g. within ~0–30ms)
• For MP3s, encoder delay means the first audible audio frame is not at decoded time 0
• During OneLibrary → djay import, this cue resolves to a negative or pre-roll frame index
• djay’s importer appears to discard such cues rather than shifting them forward

This would explain why, for me:

• Only the first cue disappears
• It happens frequently but not always
• It’s likely MP3-specific
• Rekordbox itself always shows the cue correctly

Happy to provide sample files or OneLibrary or Rekordbox XML exports if helpful.

Thanks for the additional info @rishi. I’ll let the team know.

A) SUMMARY OF ISSUE:
2 issues:

Playing from RB playlist into Djay Pro.

1. Hot Cue A is missing occasionally.
2. All hot cues are green while in RB they are multicolored.

B) DETAILED STEPS TO REPRODUCE:

1. Drag songs into RB playlist and analyze with hot cues.
2. Open Djay Pro and look at the playlist
3. Issues are there.

C) EXPECTED RESULTS:

1. Hot cue A is imported always
2. Colors are the same across RB and Djay Pro.

D) ACTUAL RESULTS:

Neither.

Thank you!

–UPDATE–

I exported the playlist to USB, accessed the playlist through the OneLibrary flow, and found the colors propagated!

However, hot cue A is still missing.

See video for context:

It would be ideal if I did not have to export to USB first to get access to the hot cue colors as well as have hot cue A export properly.

Thank you again!

Hi @marcus3, I’ve merged your topic with this existing one as they seem closely related.

1. What file types are you using?
2. Can you please share some of the music files you are having this issue with?
3. Can you please also share your Rekordbox XML file?

Thanks!

[marcus3]

1. MP3s
2. Attached 2 files with screenshots of their hot cue issues (all green and missing the first hot cue).
3. Attached.
