I am running the latest version of Cubase Pro (9.5.20) and High Sierra MacOS on an imac pro.
Whenever I mix down a track, the system intermittently freezes during mixdown. During mixdown of a full track it will freeze several times then recover each time. The entire OS hangs during these freezes. This causes problems for connected devices like UAD and the audio interface which timeout and are disconnected.
Some things I have considered…
I’ve done a full shutdown/reboot.
Temps are good during mixdown.
I have simplified the project to a single plugin with no benefits. It doesn’t matter which instrument I use.
I have switched from my RME Babyface to built-in audio and still have the same effect.
I have removed all peripherals except the licensing key and it still happens.
I can mix down a track in realtime without any problems. This is pretty inconvenient so I wouldn’t consider it to be a good fix.
Any ideas welcomed.
