It seems like the presets would load ok if you set your preferences as in PG’s picture:
“Save view settings in companion file” checked
“Save in an independent folder” unchecked
and then put the “.vs” file that contains the preset in the same folder as the .wav file. If you currently have more than one .vs file (in the cache AND in the folder with the .wav file), the correct “.vs” file would probably be the larger one. If you only have one file (in the cache folder), that would need to be moved to the folder where the .wav file is.
Those are the results I get anyway: It depends how your preferences are currently set (even if you just changed them) that determines where the .vs file will be read from, and written to.
I think it’s great that Wavelab has so many options for setting things up exactly as you want, but in the case of Master Section presets saved with .wav files, I think it gets very problematic.
If you set the following preferences:
“Save view settings in companion file” unchecked
“Save in an independent folder” unchecked
you can try to save a Master Section preset with the .wav file, and Wavelab will indicate it’s saving one, but from what I can tell it’s not saved anywhere, and the load-in will be greyed-out the next time you open the .wav file, with the preset not saved at all.
Also I don’t think it’s wise to save something as important and irreplaceable as a Master Section preset in a .vs file in a folder called “Cache” (the default location) along with other files that aren’t really irreplaceable (like .gpk and normal .vs view files which can be deleted without great impact imo). I usually think of a Cache folder as something I could possibly empty without losing a bunch of work.
I think the options which create the greyed-out condition should be re-considered. I don’t think the preset “.vs” file should be allowed to be saved anywhere but in the folder with the .wav file, because from what I can tell, if someone changes their preferences afterward, it can make the preset not available at all, until moved, or the preference changed back.
Maybe I’ve gotten some of this wrong, but those are the results I got.
