Hot Cue Lag (Quantize is OFF)

MacOS 15.3 (24D60)
Djay Pro v5.3
Hercules T7

Why is it that I notice a sound lag (delay) when I click on my cue point? Is not snappy like in serato. This happens with or without the herules connected. Quantize is OFF on both decks but the delay is so significant (almost like the delay we get when trying to cue with a bluetooth headphone). Additionally, if the cues was on a drum beat, the drum is kinda doubled (like D’drum sort of). Is there another setting I should turn off?
DJay on ym iphone 12 mini snappy and I don’t hear the delay like on my mac.

I’d try a couple things that might help figure this out

First, check your CPU and RAM usage in Activity Monitor → both when idle and when you hit the CUE… if there’s a weird spike, that could be a clue

If you’re using internal output, take a look at the Buffer Size in preferences → the lower the better, as long as you’re not getting clicks or audio dropouts

Also worth trying the version before 5.3, in case this one’s got some issue
And try turning off Neural Mix (it can be heavier on the system than it looks)

Hope that helps!

Thanks for your suggestions. I had to delete my comment above because, this lag is still bugging me. I had thought I got it fixed, only for it to re-occur from nowhere again.
Sometimes I even notice an audio glitch when trying to add a cue point on a playing deck (live).
I am beginning to think the newer versions are a bit heavy/glitchy, and hoping they are working on it. I have read other users reporting similar trends, and I saw a suggetion from the team to disable keylock (a function I love and can’t live without). I wish they gave us a latency setting to play with.

I did that. General CPU usage goes up when i start drumming my cues.

There’s no such setting for mac

Again, impossible to downgrade djay on mac. how dod you do it?

IS actually off.

Hi @Armigo, can you please try to capture a short video of the issue and upload it here? Thanks!

Hello! It’s been a week since my last reply. I’m going to consider this topic completed for now so I can focus on others. However, please feel free to respond and we can definitely revisit this. Thanks!

Hi, i open this thread again, because djay pro is really the only dj sw on the market where onpoint pressing cue or play in sync is impossible! The threadowner asked me to do a post here in the fb group because i made a thread with ecactly this problem.

I am a digital dj since nearly 20 years and tried all big dj softwares on the market → traktor, rekordbox, serato,virtual dj and djay pro

In any sw other than djay pro when you play in sync you can press cue,hotcue or play and its always on point. When i do this in djay pro and dont hit the button exactly on time the beat is visible and also audible jumping. This is more than annoying and makes a whole of my transitions or routines impossible.

I often do transitions with the fader of the incoming track fully open. In traktor or rekordbox the beats are lining perfectly without any noticeable jump. In fact it snaps on the grid and is always on time.
In djay pro when you are a little bit too early or late you can see the waveform jumping back or forward to align on the grid and you also hear it kinda glitch or it sounds unnatural and awful for a millisecond.

I have a mac mini m1, macbook pro 2017 and ipad air 2024 with m2. On all this devices its the same!

I use syn with bpm and beats on 1 beat setting but tried also all others. I tried quantize with all settings from 1 to 1/16 . I tried with and without neural engine. I tried with and without flexible beatsgrids.
Its all the same. DJAY LAGS TIMING WITH SYNC!!!

I am not the only one with this problem. And this makes some kind of preparing and performing mashups and transitions impossible.

Please,please fix this!!!

Show the video the dev team please. All other manufactures of dj sw can do this right, so i think this is not a big thing, but its holding me and others back to do a full switch to your otherwise really good and professional sw.

You can clearly see a kind of always snap to the nearest beat setting is missing or if so it lags like hell. It has to be on point. Thats the way all others do , so please fix this in a future update !!!

Hi @Tobi83, sorry to hear you’re experiencing this issue. Thanks for the video and detailed information - this is very helpful. Can you please provide more details about your specific setup?

Device Model (ex. 2020 iPad Air 4th Gen):
Version of operating system (ex. iOS 17.3.1):
Version of djay (ex. 5.1.3):
Hardware/controllers used (ex. Reloop Ready):
Hardware Firmware Version (ex. 2.7):

  1. It sounds like you are using a DJ controller. Can you please provide details on how this is connected to your device(s)?
  2. Are you using any USB hubs or adapters?
  3. Have you tried connecting to a different USB port on your device?
  4. Have you tried using a different USB cable?
  5. What music source are you using (Tidal, SoundCloud, Local Music, etc.)?
  6. If Local Music, what files types and where are the files stored (internal device drive, external drive, iCloud, etc.)?
  7. Can you please try testing with Bluetooth Off?
  8. Are you using iCloud Syncing in the djay Settings>Advanced?

First of All thanks dor your Response. I hope this thread will be taken seriously. Luke is seid ihr use multiple Apple devices in the Moment my Primarstufe device is an ipad m2 from 2024. Im on the latest ios and also 5.3.1 djay pro but this problem is inside the Code or programm of djay pro. I also tried it on my samsung s23 ultra with your android Version.

I use djay since one and a half years as a fun Tool but wann to make the switch from traktor and rekordbox because no other Company offers a good ipad dj Program with such features.

The Video was taken on my ipad without any Hardware involved!

I use multiple Controllers like flx10, kontrol s2 mk3, xone px5, xone k2 and xdj 700.

You can replicate this with ease!!!
Take 2 tracks regardless in they are local or streaming , load deck a and b, let the fader of the incoming track fully open, sync on , press play or cue or a hotcue and try to hit the beat right. 9 out of 10 Times the quantize is lagging!
It’ s the was quantize is implemented. If you re a little bit too early or to late the beat is off and quantize Hits in a few Milliseconds later. This is noticeable visually on the waveform and you haar it.

I wouldnt say anything in not All other dj programs would do it right. This is a comfort feature which a lot of people use to do creative cue teasing, mashups and pre planned transitions.

There has to be a snap on nearest beat function like in traktor.

This hast nothing to do with normal a to b mixing, where you slowly fade in the track.

I also use Cloud sync, but the problem was also way before i began to use it.

If you want i can send you countless Videos of the other Brands dj programs to see that this specific quant lag is only and i mean only in djay pro.

In the djay pro Facebook group theres already a big discussion with a lot of people who prove me right.

This feature hast to be implemented and i think this cant be a big Deal.

Please stay in contact with me. I send you everything you need to clear this.

Thanks

Hi @Tobi83, you’re welcome. Thank you for the additional info.

  1. So, is your expectation that the hot cue should snap instantly on beat when you press it or wait until the next beat? I believe your preference is to snap instantly.
  2. If you turn Key Lock Off, does it work more like you’d expect?
  3. Yes, could you please share a short video of how this behaves in one of the other softwares so I can clearly communicate this to our development team?

Thanks again!

Of Course installiert! If i press play on the download it has to be locked on instantly.

Keylock or Bluetooth off doesnt work tried both.
