Logic Pro Midi Audio and Sustained Notes Randomly Cutting Out

Hi. I've been working on arranging some Christmas songs, and have recently ran into the following problem:


Sometimes when recording, and always when playing back MIDI notes, the sounds randomly pop and cut out. For example, a piano phrase is being played, and then suddenly a sustained note just cuts out. It just stops. This is really annoying. I've reduced the following problems:


-Studio Monitor Problem

-Gain Too High

-CPU or GPU overloaded

-Happening on just that one project

-Happening on just that one track


This seems to happen at the same spot every time I play it back, and sometimes in random places. I thought that I had it fixed after changing my multithreading to "Playback Tracks", because it was working for about 5 minutes, but then the problem appeared yet again. My I/O buffer size is 256 samples, and my recording delay is -256 samples. I'm using an Presonus AudioBox USB 96 audio interface, but I don't think this has ANYTHING do do with the problem, because the popping/cutting out still happens when playing through my MacBook pro's internal speakers. The popping still happens when bouncing in real time, and is even worse in offline bouncing.


Computer Specs:


MacOS Monterey 12.5.1


MacBook Pro (13-inch, 2020, Four Thunderbolt 3 ports)

Processor 2 GHz Quad-Core Intel Core i5

Memory 16 GB 3733 MHz LPDDR4X

Graphics Intel Iris Plus Graphics 1536 MB


Please help, and feel free to ask ANY more questions.



Thanks,

First.... Recording Delay should be set to Zero <centerposition> that setting is for a specific situation where the audio interface software is not reporting the offset correctly to the system.


Second.... does that particular model have dual graphics, a separate hardware device as well as the integrated Intel Iris graphics?


Third.... Does that model have a Fusion hard drive.
