Well, okay, it’s a Cubase problem.
That’s a bit more trouble than I’m willing to go to just to keep the file size down.
There is possibly another workaround, some people have Virtual Box or other virtualization software and can run Cubase on Windows in it. This would not require rebooting or reformatting, possibly.
I don’t know enough about programming to say with certainty what happened. They say they’re not going to fix it, I have better battles.
