Hi Guys
Running an iMac with spec as below Model Name: iMac, Quad-Core Intel Core i7, 4 GHz, Total Number of Cores: 4, L3 cache 8MB.
Recently upgraded from Mojave to Big Sur.
Haven't had any issues with cores/ thread etc for years now. And yet when I imported 60 audio file stems from a project into Logic just now, the track can't play for more than 5 seconds before crashing. The CPU cores are not even registering as being used significantly- yet the I/O disk is maxed out to the very top the whole time. (See screenshots 1 and 2)
Not a single plugin in sight, by the way - just dry tracks. No busses, no processing, nada. Just audio files.
To be clear - I know all about the buffer size / audio prefs issues and have tried them all. I've rebooted several times, I've even tried different projects - with way more plugins, and similar amounts of audio files - and the threads are all divided beautifully amongst themselves, with the I/O disk not even registering, except on hitting 'start' or 'stop'. And all those other projects work perfectly. (Also see screenshot 3)
Also all other apps are closed and I've reset preferences so that's not the issue. As I said, it only happoens with this project and these 60 audio files.
i've also tried importing the files into new projects and still the same issue.
Totally mystified with this one.
Ideas? Thanks!
