Mac Studio with Logic Pro X - Latency and glitch issues

Hi there,

I recently received my new Mac Studio (M1 Max, 64gb Ram, 32 Core GPU) and have installed Logic Pro X.

I'm having a bunch of glitching and latency issues, and the CPU meter is far too alive for my liking. Having researched before buying, I was led to believe that the M1Max with 64gb Ram should be more than capable - and probably over powered, but I'm incredibly disappointed with the performance so far.

Running Logic Pro X with 6 audio channels, and a handful of plugins, and the CPU meter is running at just below 25% Processing Threads, and then spikes above that, which is very frustrating. I wouldn't mind if I was running a bunch of processing, but there's virtually nothing and all stock plugins.

I've used Logic Pro for years, and until recently on a 2015 MacBook Pro, which honestly performed better than this Mac Studio.

If anyone has any tips I'd greatly appreciate it. I've adjusted and tried various latency settings - currently I'm trying it at I/O Buffer of 64 samples, and have tried 32, 128, 256, 512, 1024 - which is ridiculous really because its unplayable with the recording delay in the upper settings. A machine this high powered should be handling this with ease.

Please help! I invested heavily in this machine and am hoping it is something I need to change in settings, because right now I'm considering returning it.

As a side note, this is the second MacStudio I've had - the first arrived DOA, completely unusable and also with massive CPU spikes. I returned it and received the replacement last week.

Thank you
