Installing .sfz files
I downloaded and unzipped Virtual Playing Orchestra. I copied each of the instrument folders to the Soundfonts subfolder in the Musecore folder in Documents as instructed by the manual. I then added the folders to Edit/Preferences/General/Soundfonts (which as far as I can see is not mentioned in the mnual!). None of the new instruments show up on the list when I'm creating a new score. I've tried shutting down MuseScore and reopening. I also reset the computer. This should be such an easy operation. Quite frankly the manual is useless. Help!
