Sometimes, the audio overlay either will not show up in the audio editor when multiple files are selected or it will show up with incorrect time representations, unless you bounce both/all the files selected. If you bounce the files before hand, this problem doesn’t happen.
Not sure what the cause is.
Windows 10. Cubase 10.
(I apologize for the weird video dimensions… I had it set to something specific in OBS but I didn’t want to change it back to normal just for this.)
