I can’t believe I found someone else with this issue. I have the exact same problem. Same result with audio. Sadly, I’ve been dealing with this for over a year with Apple support. I’ve sent them countless screenshots and recordings of the problem, with no solution to date. I use my BFP with Studio One on my M1 without any issues, but the moment I open Logic, the audio just stumbles and stutters away.
Its not the buffer, or any other setting, as far as Apple support can tell. I’ve been on the phone with them, had them tied into my system, and they can’t figure it out either. Support claims engineering is working on it, but the last tech told me to buy another interface and appears to have bailed. Not returning my emails as of today. Gonna have to make another call tomorrow.
I’m not letting these guys off the hook. I’ve got a state of the art interface, running on a state of the art MacBook Pro M1, running state of the art software, and it flat out doesn’t work. Unacceptable.
