I am trying to load my VSL libraries in a new project but some of them show up orange instead of blue, which I think means they are not loading?
It means the player doesn’t know where they are. You can locate them with Vienna Assistant
Unless there are still other Symphonic Riot Doricians who could verify, I’d check with the company on that one. If my memory serves me correctly (unfortunately I no longer have VI libraries installed, otherwise I’d check), I did see some “red” matrices. I’d have thought it’s pretty unlikely that certain flute articulations would be in a different location from others, though of course nothing can be ruled out.
