Issue with track stuttering and freezing when scrolling quickly through tracks

I’m experiencing an issue where rapidly scrolling through a track (using the ‘<<’ and ‘>>’ parameter buttons on the Mixon) causes stuttering and short freeze moments in the track. You can see this in this attached video.

A couple of notes:

  1. I feel this issue is more noticeable with longer tracks (the track in the example is around 6 minutes).
  2. Other similar software doesn’t seem to have this issue with the same action, and it shouldn’t be a problem for Djay here either (especially since I’m not using heavy WAV or FLAC files).
  3. Initially, I thought the issue might be related to having used sync for a mix transition with the track, or possibly that the problem was tied to one specific file. However, later in the video, you can see the same issue happening with a different “fresh” track as well, and without having done a mix transition beforehand.

This leads me to think the issue might be more related to the system becoming unstable after performing any other activities, such as mixing, starting/stopping tracks, starting from cues, or similar actions. After a quick retest, I noticed that the issue is perfectly reproducible and occurs on both decks.

I also recorded and saved a Diagnostic System Test during this behavior and saved the .tar.gz file here: Diagnostic System Test

Has anyone else experienced this or found a solution?

@Slak_Jaw: can one of you please check the video and activity dump file?

Thanks in advance for your help!

Has anyone from the Algoriddim team already been able to replicate this issue @Slak_Jaw?

Hi @DJ_Big_Blender, sorry I was busy catching up with other users before my holidays and didn’t have time to investigate this one. I’m OOO until Jan 26, but you can submit an official support request from within djay. I hope that helps!

Hi @DJ_Big_Blender,

Wanted to pop in and share that we have yet to reproduce the issue in question.

I did want to thank you for the video though, it has been helpful in our testing.

We will reach out soon with next steps via this thread.

Thanks!

Thank you, @NathanielAlgo.

Is it possible for you to look into the log that must have been produced during the live set I performed last Saturday night (January 18, 2025)? The set started at 19:46 and included 77 songs.

During that set, again I encountered several issues, such as stuttering, stopping, and tracks that wouldn’t start.

I’m not sure exactly what is recorded in the log, but I hope it contains some clues.

I also just sent an email directly from DJay app on MacBook to support.

Of course, looking into the log refers to this issue as well as another one that you might already be aware of:

Hi @NathanielAlgo and @Slak_Jaw,

I believe I may have found a breakthrough :pray: after retesting this issue thoroughly. I tested it with a few different tracks, as shown in the video and this all points in the same direction!!

(Additionally to the video, I tested it with Neural Mix activated on Deck 2 and normal settings on Deck 1. The stuttering and freezing occurred on Deck 2 but not on Deck 1, making the test quite convincing. Also, when assigning an effect to one of the Neural Mix stems, the problem appears as well.)

So, it appears to be directly related to using Neural Mix (which I have mapped to the EQ knobs). This makes sense to me a lot because I use Neural Mix quite often, and since I’ve been using it more and more, the issues have also increased.

Even the issues arise in cases where the Neural Mix knobs were still “active” because of the previous track—as you obviously don’t always reset the knobs before loading a new track.

This root cause, involving Neural Mix probably together with something like caching, could possibly also be connected to that other persistent issue I experience—tracks that won’t start, stutter, or fail during live sessions.

:point_right: I think I’ve now pointed you in the right direction to resolve this. Given that Neural Mix is one of DJay’s key USPs, I strongly believe this should be fixed as a priority. Users rely on this feature, and it should work flawlessly in all situations.

Here’s the video: DJay > Stuttering & Freezing has to do with Neural Mix

And here is the other issue I am referring to: Issues with track loading, playback, and crackling sound (Mixon 8, 2019 macBook Pro)

Hi @NathanielAlgo and team,

I hope for your continued support in investigating this issue. Since I haven’t heard anything for 3 days, and I’m eagerly awaiting a response to my latest findings regarding Neural Mix messing up the stability.

Last time, you mentioned, “we have yet to reproduce the issue in question.” With the additional testing and evidence I’ve provided, I believe this should now significantly aid in pinpointing the root cause.

As this issue is severely impacting live performances, I kindly request an update at your earliest convenience. Additionally, I plan to start a new thread to see if other users have encountered similar problems, which might provide further insights for your analysis.

Looking forward to your swift response! :pray:

Best regards

Hi @NathanielAlgo,

Following up on my earlier post, I’ve even been able to narrow down the issue a bit more.

The stuttering and freezing seem to occur only when I use the Skip Forward or Skip Backward buttons on my Reloop Mixon 8 Pro controller. If I scroll through the waveform manually with cursor (forwards or backwards) using the DJay Pro software, the problem doesn’t happen—even when the controller is connected, and the audio runs through it.

I’m curious if anyone else using a Controller (Mixon 8 Pro or other) has experienced this as well.

Have you noticed the same behavior when using the Skip buttons?

Any additional insights would be greatly appreciated!

ATN I am on the current version of DJay (5.2.8.)

Hi @DJ_Big_Blender,

Thank you for all this additional information!

Our engineering team really appreciated this update.

They are continuing to look into this and we should have an update from them soon regarding next steps.

To be clear, you were experiencing this stuttering on v5.2.6 as well, correct?

Thank you!

Hi everyone,

Could you test something for me?

I’m reaching out to see if others like you have experienced similar issues with stuttering, freezing, or tracks not starting properly after using Neural Mix in Algoriddim DJay.

I will show it to you. In my case, I have toggled Neural Mix to the EQ knobs. but I’m not sure if this is related, but the issues also persist if the Neural Mix settings aren’t fully reset before loading a new track.

:fast_forward: You can see for yourself(*) in this video the problems I encounter. Like you can see there also seems to be a 100% correlation between these problems and quickly scrolling through a track.

(*) E.g. on5m02, 5m32 and 8 min in the video

If you seem to have this problem as well, could you please share your experience?
Specifically:

  • What hardware are you using?
  • Does the issue occur only after you ‘activated’ Neural Mix in a track or also without?
  • Have you noticed any patterns or specific triggers?

Your feedback would be incredibly helpful, both for troubleshooting and for providing the developers with more insights to resolve this.

Thanks in advance for your input! :pray:

Best regards,
DJ_Big_Blender

For reference I’ll add the original case:

I am working with Neural Mix in this way, but I believe that enabling it using the pads will likely cause the same problems.

Hey @DJ_Big_Blender
I tried this. It works fine.
I am using no 3rd party hardware.
Maybe process of elimination?
Disconnect your hardware and try again.
Also, when in doubt, reboot your Mac.

Ok thanks for trying.

So you are only using a laptop? Mac or Windows?

Reboot the Mac I already did many times.

Hey @DJ_Big_Blender
I only use the Mac for iTunes to sync with my devices. I do not use djay on the Mac at all. I’m a non-pro so I really don’t need the map at all. I just need it to sync.

Yes, sure otherwise i couldn’t have it already for so long

Hi @DJ_Big_Blender,

Thank you for your patience with this matter and for the additional information. We have some good progress news.

Our teams believe they have pinpointed the issue, but we’d like to ask you one more thing.

In djay, the skip controls behave slightly differently than waveform scrubbing. It would be interesting to know if you can reproduce this issue with the skip / beat jump controls in the app without a controller.

Looking forward to your findings!

HI NathanielAlgo,

Thanks for the update and for looking into this issue!

I tested it as you suggested, using the skip / beat jump controls directly in the app without a controller, and I’m seeing the same problems occur. However, when I scroll through the song by clicking randomly on the waveform of a playing track, it goes smoothly without any hiccups.

So I wonder is this good of bad news for your findings?

Let me know if you need any further details!
