Push 3 Screen Latency

[b-righteous]

Anyone else notice latency with the play head and meters since 2.4?

The play head in clip view is very late compared to the audio and it skips to try and catch up. Using in controller mode and there is definitely a difference between the push screen and the GUI. Also the mixer meters are way off. This was not the case before and I think it started with 2.4.

Are you seeing this with every Set?

[b-righteous]

Yes. Sometimes its more noticeable than others.

Since it's not constant, you need to try to find out what in a Set can cause this when it happens - could be a 3rd party plugin, maybe a M4L device, a non-optimal latency setting...
Also, if you encounter this in a Set created prior to 12.4, try opening that Set with 12.3 and compare to see if there's indeed a different behavior.

Actually, it is constant now that I am testing. Using the factory default new project and only loading a factory drum kit. In particular, the mixer meters are definitely way more latent then before. Earlier this year, I compared this directly to my KKMK3 meters due to me noticing they were latent. Push 3 however was right on point.

I tried the factory USB cable and it made no difference. I also reverted to 12.3.5 and got the same result. However, there was a firmware update to the Push in one of the recent updates. I bet it's related to that. This is a serious issue. Basically renders the mixer screen useless and makes it difficult to edit midi events due to the time discrepancies.

Tested per my same Lynx Hilo TB ASIO interface using 256 buffers @96k and 128 buffers @48k on Windows 11. It's possible this issue does not affect standalone or OSX but surely there is an issue with recent firmware and Windows.

Okay, here is what I noticed for the mixer meters. Real time input is near instant feedback when the sequencer is not in play. If you hit play, the meters are very late reflecting drum hits you triggered in real time. Of course, sequencer playback is also has delayed metering. Really strange.

Can anyone else please test?
Repro:
Create a new project in controller mode.
Set audio buffer to 128 or 64 samples.
Load a drum kit.
Press mixer view on Push 3
If desired, press the lower button of the selected track to unfold the kit.
With the play button disengaged, Trigger some drums.

Result:
Notice the meter feedback from the drum hits. Should be close to real time.

Now push play and trigger the pads again. Notice the meter responds like a second or more later.

Still getting this. I thought it was consistent since I was able to get the behavior multiple times. However, its not. I think recording triggers it, possibly fixed length. When it happens, the same result of meters being delayed only when the sequencer is playing. When that happens, the clip view play head is also delayed and skips ahead to catch up every 1 or two bars. Have not reported because I can't reliably reproduce.

I can't repro, but I don't have any windows machine to try (that being said we did get other windows users commenting on this; so it might be something very specific with your setup).

Have not reported because I can't reliably reproduce.

Next time you see this, generate a Status Report and send it to Support.
Hopefully these logs will tell something helpful.

Will do, thanks for the tip. Will file a report when I get some time. Once a project is saved in this state, the bug is always there when loaded. So I should have an example set to attach.
Edit:
I think the repro is pretty simple.
Start a new project in controller mode.
Load a drum kit to the first midi track
Press the Mixer view on Push 3
Play the kick and snare and observe the meter for the track. The meter should respond instantly.
Press play button and play kick and snare again. Meter should still be responsive.
Ensure layout is in loop selector mode.
Press a loop selector pad which will load a clip.
Now play the kick and snare and observe the latency. At this point there is a very noticeable delay with the meter.
Hit play button again to stop transport.
Play kick and snare. Notice no latency on the meter when sequencer is stopped.

You may need to lower your sound card buffer so that pad strikes are giving instant audio response. This will help spotting the difference.

I definitely can't repro following your steps, even with buffer @32smpl.
Do you have "reduced latency when monitoring" active maybe?

[b-righteous]

Thanks for checking jur, are you on Mac or Windows? I will check the reduce latency option later. I am pretty sure it would be at default. I will also reboot and power down all controllers (SSL UC1, Komplete Kontrol MK3 and Console 1 MK3) to try and isolate the issue.

Oh great idea... glad you mentioned that earlier

On mac here.

[b-righteous]

Okay, I shut down and unplugged all the controllers other than Push 3. Launched Live and all was working. Added Console 1 and then KK MK3 and all is still working. Noticed the lag that was on KK MK3 mixer is also gone.

Wondering if its the SSL? Have not plugged back in yet. Will have to investigate further and report back.

[b-righteous]

Yup, its the SSL UC1. Attaching brings latency back. Remove and it goes away. I think the KKMK3 also adds a touch of lag too, just not nearly as much. Could be a USB issue or something with the SSL drivers. Changed USB Cable and plugged in direct to bypass hub. Did not make any difference. Probably just going to sell it since I use Console 1 more.
