A public preset configuration (V 3.2) for the use of the
Vienna Choir (Standard + Extended) with the Capella notation software
was published on the CapellaWiki:
Capella and Vienna Choir
(under "capella-tune - VSTs einbinden und mehr" there)
It runs with Vienna Ensemble and the VI Player (Windows 7).
Please note: The configuration, including its description, is in German only (as is the CapellaWiki website).
Have much fun,
