Logic has been ported long ago and runs natrive without Rosetta. Maybe you have some plug-ins that require Rosetta? We dfo have new M1 systems and do a lot of load tests with Loigic, and have not seen it 'stuttering' unless it is overloaded from plug-ins.
Also you did not tell us what driver you use - the old 3.27 or the newer 4.04?
The driver is 4.02.
Logic runs fine natively with the other interface. I do have a few plugins that require rosetta, that does not seem to cause any problems even with native ARM Logic. I tested some logic sessions with stock plugins only with the same 'stuttering/looping' with the UC. I also made A/B comparison tests with several logic sessions testing both interfaces one after the other on the same session.
I don't think it is related to cpu usage in the conventional way because in that case playback would just stop (or playing distorted audio sometimes). In my case it keeps repeating a very small part of the session, like a mini-loop. I have a screenrecording i could send to you if that would help to understand the behaviour. And it keeps playing back that small loop until i stop it. It is very different to a normal cpu-overload. It seems to be triggered more easily on bigger sessions.
Unclear statement as you did not explain exactly what the main issue is. If the audio stutters then (obviously) DC's visualization of the audio will show the same. If audio is ok and only the graphic output of DC 'stutters' (no smooth elvel meters) then this is something different.
In my case with a cpu overload logic would just stop playback. I never had that kind of freeze in DC with a cpu overload, the bars would just fall down smooth normally.
Is that an interface that runs in class compliant mode, without drivers?
Yes. There is software for monitoring, but i don't think it qualifies for a driver. It still works without it.
