Logic Rosetta / native plugins

Just curious if anyone knows this. On an M1 mac when running logic through rosetta, if I load plugins that have native M1 versions (like fabfilter nexus) are they loading the apple silicon version, or they running the intel one, since logic is running the intel version..?

Good question, I'm curious too. I wonder if there are any plugins that are M1 only - if there are, and they also work under Rosetta2, then that is your answer Edited April 27, 2021 by Eriksimon

Yes that's be a quick way to answer but unfortunately i doubt there's a plugin like that.

I think plugins are spawned as separate processes now, so you might be able to see in Activity Monitor which architecture is running from a loaded plugin perhaps?

Yes a tried that, but couldn't find them as a separate process in activity monitor

Important

The system prevents you from mixing arm64 code and x86_64 code in the same process. Rosetta translation applies to an entire process, including all code modules that the process loads dynamically.

Once you specify Logic to run in Rosetta 2, only Intel plug-ins get loaded.

Yes, but I thought they changed plugin handling in Logic *specifically* because of this. In the same way, people have said that running Logic ARM-natively can still load Intel plugins - precisely because the plugins are moved to their own process, so you *can* mix architectures.

 

That's what I understood, from user reports (don't have an ARM Mac so don't know directly.) but prehaps someone that does have one can answer definitively...

That's not what the OP is asking.

They want to know if a x86_64 app can load arm64 plug-ins. The answer is no.

Once you're in x86_64, it's only x86_64.

Ok, thanks for the confirmation. And running natively, you can load both ARM and Intel plugins?

yes, running natively, intel plugins load thru rosetta2, and arm plugins load directly.

 

am wondering when rosetta2 will end (2 years perhaps?) and wondering which plugins i'll lose when that happens. but for now, seems a good place to be.

Not sure if this will help: https://apps.apple.com/us/app/pluginfo/id1626412949?mt=12

PlugInfo is great, I helped with testing, and among other things it will tell you which architectures a plugin supports. It's highly recommended and I use it pretty much everytime I install plugins.

It doesn't of course change Logic's handling of native or Intel plugins.
