Hello Jonathan and welcome to the forum!
We offer Finale 2008 and Finale 2009 Human Playback Preferences for our Vienna Special Edition customers as a free download. This means that articulation changes will work automatically, just as you are used to from the Garritan library.
All the details about the Vienna Special Edition can be found at the following location:
