hmmmm…that doesn’t seem to change anything.
But it did make me look at the options when I Replace Audio File with a new clip with a different name.
On the import dialogue box there is a check box to copy the file to the montage folder - I unchecked this - so now the montage is referencing the file in my OneDrive folder, not a copy on my D: drive.
So I tried again to change the mix then replace the file in my montage - and back to the same problem - the file has changed, but Wavelab doesn’t see the new file. When I click edit source and look at the path in the File tab of WaveLab, it shows the correct path on OneDrive (C:\users<my username>\onedrive\mymusic<file name>)- but WaveLab hasn’t recognised that the file has changed.
