In the video I linked to, I demonstrated that putting something in a track stack with an amp and compressor causes immediate latency and doing it outside the track stack doesn't.

That's not what's going on. This was happening months before the Mastering Assistant plugin was even released.

I have posted a few times recently because of the latency issues I've been experiencing for months. My projects are relatively small, they only use native plugins, lowest buffer setting, and my M2 is very fast, so I haven't been able to find an obvious culprit. Then tonight for the first time I was able to recreate the problem consistently. Basically using the "summing" Track Stack caused the issue — https://www.dropbox.com/scl/fi/ul6l8wwe6zdvklzc5uno0/latency-track-stack.mov?rlkey=mlblth0my90yalb5ai7edpqsp&dl=0 I use track stacks a lot for when I have 2-3 guitars running into the same amp sim. If this is a known issue, I feel dumb for not knowing it!

Curious if anyone able to play on the Take 1 track and experience the latency issue?

For anyone interested to try, this is a zip file of the project in question. https://www.dropbox.com/s/s5iqhs6rx1mcol4/latency issue.zip?dl=0 The "Take 1" track lane is where I'm experiencing latency issues (although not crazy, but enough to notice). The buffer size is currently set to 32 for me in Logic. I was also told that increasing the sample rate of the project from 48 kHz could help. Appreciate the help.

I really appreciate the feedback yall. Tomorrow I will start a file from scratch, add parts, wait for the latency issue to begin, then upload the file to Dropbox if anyone wants to check it out. I will be more careful to note what triggers it. No idea if this is related but wanted to add — a few years ago I bought three plugins from Waves which I ran on the old iMac. When I set up the new Mac Mini in August, the Waves installation process seemed like it had changed in the meantime where I had to install a desktop app and even though I only paid for three plugins, when I browse the Waves item, I get a zillion (demo) plugins in the menu (see attached). Even though I'm rarely running the plugins could this be related? As far as version, I'm running Logic 10.8, and then Sonoma 14.1.1. Interesting... gonna try to add and remove those and report back... thanks!

Yes — whenever I notice the problem, I try the buffer at all sizes, including the lowest, and nothing changes. Essentially once the problem starts in a project, nothing makes it go away.

That's the frustrating part. I definitely get how latency works. I'm just not understanding why I recorded with my previous iMac for six years and never encountered latency issues no matter what I was recording. It's only since getting the Mac Mini. So the concept isn't new, it's just that it's cropping up in ways I would not have expected (very simple project, 1-2 native plugins).

Just to be super super clear here though — I am currently recording a project that has two acoustic guitars and an electric guitar. The acoustic guitars are using a send for the native Silververb plugin and the native Delay Designer plugin, and that's it. There's no weird third party plugins running or anything excessive. Also I have been making very layered ambient music with lots of plugins running throughout the various Logic projects for 5+ years with zero latency problems. It was only when I got the new Mac Mini that this started. I'm just really confused. The projects I'm creating are not particularly resource-intensive. I did purchase a couple plugins from Waves (though I'm not running them) and the menu picker loads a bunch of plugin previews - would that be running in the background possibly and slowing anything down?

That's the weird thing though. When I used the iMac, I never had this problem, even when running multiple plugins. Also in the example I gave (trying to record simple acoustic guitar with two mic's running), I was running *no* plugins at all 🤔

Up until recently I used a 2018 iMac with a 2018 Presonus Audiobox and very rarely got an latency issue when recording. Then I upgraded last month to a brand new Mac Mini and have since gotten the issue frequently. Example: I have two mic's positioned to record acoustic guitar in two separate channels simultaneously. Whenever I do anything like that, suddenly there's a slight delay in the sound in my headphones. (I have tried Low Latency Mode but when I do that, it removes the effect of reverb plugins or whatever else I have running as well as reducing volume). Sometimes I adjust the buffer up or down but only sometimes does that actually fix the issue. I know this is maybe an interface question and not a Logic issue, but perhaps a faster or more modern Thunderbolt-enabled interface would help?

Hmm. So how would I record accurately with the amp sound turned off...?

When I turn it on, it kills all the amp sound and effects - is that normal?

It actually seems fine on new from-scratch projects, seems to only give me troubles on older projects from before the switch.
