Logic 10.4 Audio region tempo changes randomly
There's this thing happening since updating to 10.4 that is driving me insane.
Firstly, Smart Tempo and Flex are all off (attached)
When I record an audio region Logic will randomly change the tempo of the region, or to put it better, it starts at the correct tempo and then drifts out of time. Occasionally, after this happens I get an error warning 'One or more regions contain user-edited flex markers (attached). Again... Im not using smart tempo and I'm not using flex.
I wish I could go back to 10.3.whatever. This is causing me a massive waste of time.
Hope someone can help.
iMac, macOS High Sierra (10.13.3)
