I started noticing this same thing happening in 9.5. I went nuts trying to figure out what was wrong. The only way to to get the waveforms to display was to go to Audio Process and normalize and then it would show up. This was weird because I never had to do it before. It turned out to be a corrupt project file. I wound up reinstalling Cubase and so far so good.
Thanks for chiming in - did you find it was only a problem with the one project file? At the mo it seems to be all of my current projects. Will try the normalizing thing when I’m back at my desk…surely that’s not the long term fix though Reinstall hasn’t solved my problems thus far.
Seemed to be random. I checked the audio pool after normslizing, and the waveform still did not show. Aksi was having random problems with midi trigger on random tracks. So i went the reinstall route.
Just updating incase anyone is following this thread after the same issues,
Sadly, this looks to be an issue with Cubase 9.5 no longer being supported in current (and future) OS.
My solution was to do hard reset to Mojave, using Time Machine to revert / reinstall. I’ve lost some files but, thankfully due to the tech issues, I’d not done any major work on this machine since the update to Monterey.
My Mac is now back on Mojave 10.14.6 and Cubase 9.5 is working fine.
I’m sure issues with other software will now appear, but at least I can get on with this music job.
No, it seems to be random with other project files. I actually re-installed but no difference. With that said, I did not do a lean install as I did not delete the preference files in the system folders.
