Beat not in sync with visuals

There was an error rendering this rich post.

Hi.

I recently had Traktor Pro installed on a laptop and when I loaded any tracks from Beatport, I could just play them immediately and they were synced. I created mixes with comments on each track so I knew where to start each one etc.

I've a new laptop and installed Traktor Pro again, and it's a mess. I've tried mixing previously complete mixes again, but they're always out.

The issue I think is that the visuals don't match the beats. In the visual below, this is where the beat hits, not at the start of the block as it should be. Obviously this is an issue when beat matching.

When loading tracks, this is what is selected by default.

Does anyone have any ideas? Why don't the visuals match the beats?

Thanks for any help.

You aren't using Bluetooth headphones, are you? Bluetooth causes high latency, so Traktor will play the music and there'll be a significant delay before it reaches the headphones.

Oh. My. God.

Are you serious? Using Bluetooth headphones messes everything up?

Everything is now as it should be. That's crazy.

Huge thanks to both of you for your help. I can now use it again.

Nice find. I did not expect you to use wireless headphones.

If you want to stay wireless. aiaiai will release some wireless dj headphones this year, they claim sub 10 ms response time. https://aiaiai.audio/headphones/tma-2-dj-wireless (But please don't pre order, wait for reviews)

Just another one as an example. This position is the downbeat for this track!

lord-carlos

First one looks good, it's it drifting of later on?

If the downbeat is wrong you need to change it.

There has been no changed to the bpm / grid detection in the last couple of years. So an older version would grid it the same.

Thanks for coming back so quick. It's not drifting, it's out from the start.

Downbeats used to hit on the flat side of the visual on the white marker (shown with arrows below) but now they hit afterwards. In this case of this track it's actually where the smaller purple blob is. It's the same for all tracks but they used to load correctly, so it's something new and not track related.

The first track you posted does not have a 1st beat marker or any beat marker, it only has the transient beats that Traktor Pro sees so you can only manually beat match with those track, old school style. Sync will not work with any track without a beat marker.

Do you have "Analyze new tracks when loading into deck" unticked? (File Management in preferences)

Sure do as shown.

shepnic

Ah yes. This was because I was messing about with it to see if I could fix the issue.

This is it when loaded with the downbeat happening at the first purple spike.

What buffer size have you got in your audio settings? What is the reported latency?

lord-carlos

If I remember I can try to take a look at those tracks later, but from just the screenshot the beatgrid looks correct.

But like I said, nothing has changed with how Traktor analyzes the tracks.

Is the problem that the grid is not correct, the one / downbeat not correct, or that they don't stay in sync with other tracks?

Here you go.

The problem is that visually it looks like the beats should be at the large spikes, and this is also what Traktor is assuming when it does the beat grid. But that's not where they are.

So when playing another track and then mixing another in, it's not starting at the beat. So there are two things - beat not starting in the correct place, and visually the beat isn't showing correctly.

lord-carlos

Then you probably have to change the grid manually for those tracks.

You aren't using Bluetooth headphones, are you? Bluetooth causes high latency, so Traktor will play the music and there'll be a significant delay before it reaches the headphones.

Yes, WH-CH520 are Sony wireless headphones!

Also a buffer size of zero is going to be a problem, regardless. There has to be a buffer. No sample rate shown either…

@shepnic use wired headphones or speakers and your issue will vanish.
