When launching Wavelab, it comes up with the default Welcome window. At this point, it is not possible to double-click a .mon file to open the montage. It would be nice if this could be possible.
I don’t see what you mean. In the startup assistant window, you can double-click audio montages listed there.
Sorry, maybe I should’ve been more specific. If Wavelab is launched and the welcome screen is up, it’s not possible to open a montage by double clicking on the .mon file in Finder on macOS. Also, it is quite usual that my “recent” montages aren’t populated at all in the welcome screen, and I have to create a default project first and only then open the montage.
Sorry, but this cannot be changed. Simply double-click on the montage file before opening WaveLab.
