Blue scrolling waveform with missing info

NOTE: Please use the search function above before posting to avoid creating duplicate topics.

  • Device model M1Max
  • Version of operating system 15.6.1:
  • Version of djay 5.5.1
  • Hardware/controllers used N/A
  • Hardware firmware version N/A

A) SUMMARY OF ISSUE:
Occasionally, tracks load and play normal for a few bars and then show collapsed blue waveform while the sound breaks down

B) DETAILED STEPS TO REPRODUCE:
Random, but often on a track’s first load. Reloading the track fixes the error, but makes DJing live risky.

C) EXPECTED RESULTS:

D) ACTUAL RESULTS:

I also get those when I edit 2 metadata fields within djay while the track is playing on deck…or so i thought. ((Just tried it now and it refused!))
Has never happened on it’s own though. Is your drive not disconnecting?

Hi @Wuli, thanks for the details about your setup and the screenshot.

  1. Is this with streaming music or local music?
  2. If local music, what file format and where are the files stored?
  3. Since this sounds repeatable, can you please capture and share a short video of the issue to help clarify what’s happening? Thanks!

I get similar behaviour when I edit the metadata of a track playing in a Deck. In my case, the audio waveform disappears; deck is still “playing” but the waveform is blank - so no sound. Re-loading the track resets everything.

It is a very inconsistent issue, difficult to repeat and trigger. Unfortunately, just when I think it is safe, BAM! - it happens.

Current Theory:

  • Seems to occur with local un-analyzed AAC files → right when I first add cues and metadata.
  • Analyzed files seem to be more bullet proof, but I am still trying to prove that it only happens to un-analyzed files.

  1. This is local music on my main HD. It first happened when I was using iCloud Drive, so I ended up moving my collection to my main drive; however, the issues continues. It is random, and it can be days or even weeks between an incident, but often when it does happen, it happens several times during that DJ session. This has been happening for quite some time, so it’s not an issue with a recent release.
  2. File format is Apple Lossless. Most of the files have been processed through Platinum Notes, and are 48kh m4a.
  3. I’ll do try and get a screen recording the next time it happens. Sometimes it can be days, other times weeks until it does happen.

Thanks for your help!

Oh, one other thing.
It does seem to happen more often when I hit the transport quite fast after loading a song. When it starts happening at a gig, If I let the songs load for longer before cueing or hitting play on the transport, the issue seems far less likely.

Thanks for the additional info @Michael_Wisniewski and @Wuli. I’ve passed this onto engineering for further review.

NOT in my case. I have MP4 and happens too. My library is 100% analyzed and I still get that blue thing most times in the heat of a gig (like past an hour or 2. I still believe this is related to the fact that newer updates have made djay quite too resource-heavy on many even capable macs, noting as the example here was an M1 Max silicon. It’s worse on intels…where i belong. (Perhaps for some buggy reason djay keeps forgetting it has already analyzed the some tracks and re-analyzes it on loading? Prior to v5.5 I had some experience like that)

I already made a suggestion the developers need to start thinking of a separate version of the djay app for intel macs, becuse at this rate, everybody will have to be on M5 macs/ipads very shortly.

Thanks for the additional info @Armigo

Hello @Wuli, @Armigo and @Michael_Wisniewski, so far we have not been able to replicate this on our hardware. In the djay Settings>Advanced, can you all please confirm if you have the following setting enabled or disable? Thanks!

Enabled on mine. Is it the culprit?

It is enabled in my settings as well.

Thanks for confirming @Armigo and @Wuli

Hi again @Wuli @Armigo @Michael_Wisniewski, we are still not able to reproduce this on our end. Since this issue seems to appear under different conditions for each of you, it would help us if we can identify what your setups/settings have in common. For example:

  • whether you pressed Play immediately after loading
  • whether the track was already analyzed
  • if “Double-click song in library to edit metadata” is enabled (this could be a contributing factor, though not conclusively)
  • any metadata or cue edits made while the track was playing
  • the file format used (ALAC / AAC)

If we can identify a consistent pattern of actions that lead to this behavior, we might be able to define clear steps to reproduce the issue on our side. The more specific the circumstances, the better our chances of narrowing this down. Thanks!

Generally speaking, the times the issue has occurred for me I have

  • pressed play immediately after loading
  • Yes, the tracks were already analyzed
  • Double-click song in library to edit metadata IS enabled
  • No metadata or clues edits were made
  • File format is Apple Lossless m4a 48k exported from Platinum Notes & key tagged with Mixed in Key

@Michael_Wisniewski and @Armigo, are you also using Platinum Notes, Mixed in Key or any other 3rd party audio processing software?

  • I do both: 1. press play immediately and then edit metadata 2. Edit metadata 1st, then press play. Error has occurs under both conditions.
  • Both: some tracks are already analyzed, some are newly imported. Error occurs under both conditions.
  • “Double-click song in library to edit metadata” is enabled.
  • Hot Cue editing works fine (no errors), it is only when metadata is edited. I have tried this with freshly imported tracks with no cues and then also added cues, in both cases editing the metadata triggered the waveform error.
  • file format M4A/AAC

Thanks @Michael_Wisniewski

@Michael_Wisniewski and @Wuli, can you please try to reproduce this issue with songs that you have not processed with any 3rd party software like Platinum Notes, Mixed in Key or MP3Tag?

@Armigo can you please confirm if you are also using any 3rd party software on your music files?
