Match results inconsistency: List changes randomly when switching Deck focus

Bug Reports
1
  • Device model: MacBook PRO M1
  • Version of operating system: macOS Sequoia 15.7.1
  • Version of djay: 5.5.2
  • Hardware/controllers used: n/a
  • Hardware firmware version: n/a

A) SUMMARY OF ISSUE: Inconsistent Match results: The list of suggested tracks changes randomly when switching Deck focus back and forth, even though the source track has not changed.

B) DETAILED STEPS TO REPRODUCE:

  1. Load a track onto Deck 1.
  2. Open the “Match” panel to view the suggested tracks (let’s call this List A).
  3. Switch the active focus to Deck 2 (e.g., by clicking on Deck 2 or loading a track there).
  4. Switch the focus back to Deck 1 (without changing the loaded track).
  5. Observe the new list of suggestions in the Match panel.

C) EXPECTED RESULTS: The list of suggested tracks should remain identical to the initial list (List A), given that the source track on Deck 1 is exactly the same. The results should be consistent.

D) ACTUAL RESULTS: The Match feature generates a completely different list of tracks compared to the first time. It seems to re-roll/shuffle the suggestions randomly every time I regain focus on the deck, which makes the feature unreliable.

(Note: I’ll try to upload a video showing this behavior as soon as possible).

That is expected behaviour for match within djay. The feature is just not very good.

Thanks for the input! I totally get your point.

I understand that this might be the current implementation, but as you pointed out, it is certainly not optimal.

From a logical standpoint, if the source track doesn’t change, the results shouldn’t change either. Until the team explicitly confirms that this randomness is intended behavior (which would be strange), I believe it should be treated as a bug

It’s an on going thing here

Thanks! Yes, I am aware of that thread and have already upvoted it.

In fact, I came directly from there to create this new post. @slak_jaw suggested I open a separate topic specifically for this issue.

Hi @Albert_Maro, can you please share a short video of this? Thanks!

I managed to record it. Check out the video: notice how when I move the fader to Deck 1 or Deck 2, the Match list changes immediately. It doesn’t stay consistent; it proposes new results every single time.

Just to be clear, the filter is set to ‘My Music’.

Far from being an intended feature by Algoriddim, I am convinced this is a bug for two reasons:

  1. The list simply shouldn’t change on its own just because focus changes.
  2. I have over 500 songs in my library. I find it hard to believe that only 20 are matches. The fact that it shows different tracks every time proves there are more matches available, so hiding them behind a random shuffle makes no sense

Thanks for the video and additional info @Albert_Maro. This is very helpful. I’ve shared this with our engineering team.
