Setup details:
- Two turntables with Phase DJ system
- Pioneer DJM-S7 mixer
- djay version: 5.3
- macOS version: 15.4
- Device: 2023 MacBook Pro M3 Max
Summary of the issue:
I’m experiencing a sync-related issue while using djay in Sync mode with both BPM and Beat enabled. The problem occurs when two tracks are synced — initially, they are aligned correctly, but after a few moments, a noticeable drift between the beatgrids develops. This results in the tracks going slightly off-beat, even though sync is still active.
This behavior can be seen clearly in the video I recorded. It seems to happen inconsistently but often enough to affect live performance reliability.
Your right deck tempo is a little to the left. Your tempo knob is just above the left and right channel vu’s. Mine does that sometimes. I’m not sure if I have a mapping in a weird spot or I slip with my finger on my phone, but that’ll be the cause of the drift.
Thanks for your reply! However I am not sure if I understand. Are you referring to the pitch slider of the turntables?
As you can see the pitch slider on the right deck is neutral in the middle. The pitch slider on the left deck is not neutral but I think for djay it doesn’t matter where the pitch slider is. When sync is enabled bpm should simply match if I understand correctly…
Still unclear to me what causes this issue…
The software itself. I included a screenshot. There’s some non intuitive logic when using DVS, and I’m not sure how it gets activated but it works as a secondary tempo that overrides the sync I think. Click the knob there and hit “reset” on tempo and it should fix it.
Isn’t that the digital gain dial that controls the volume of the channel?
Oh possibly. The phone and desktop layout is quite a bit different I guess. Take a look for a tempo spot then, I’ve had this issue before and that’s what it was every time. Either that or calibrating when turntable pitch were modified.
Hi @trebbis, thanks for the details about your setup and the issue - this is very helpful! Our engineering team was able to replicate this issue and is investigating further. I’ll report back here when I have more news. Thanks!

Any news about this? I was able to replicate this issue too. I’ve noticed it seems to happen more the longer you play, at least in my experience so far.
Hi @Austinjacobm94, thanks for the additional info. Our team is still working on this. I’ll share more news here when I have it.
