I think I've forgotten a step in setting up a new VI instrument, it's been so long since I bought one. I bought Dimension Strings I and Fanfare Trumpets, used Vienna Assistant to download and (I think) install them, and added the folders containing them in the Directory Manager. But when I opened Vienna Instruments Pro, there was no sign of any new patches in the Patches tab.
Am I missing something? I could believe Dimension Strings runs on a different player, but that seems odd for Fanfare Trumpets.
