There is a VI called The Strings of Winter that can be purchased separately.So, what you're saying is that with The Orchestra Complete, it:
1) Does include the Strings of Winter ?, and,
2) Does not have a separate interface for Strings of Winter ?
Talk about confusing!!
There is The Orchestra Complete, which integrates all the instruments in The Strings of Winter into The Orchestra Complete. So you get the new string articulations added to the old string articulations. I think they made this pretty clear.
Over time, I am sure there will be many new libraries in The Orchestra Series
Maybe The Brass of Spring, the Woodwinds of Autumn, the Drums of Summer. Anybody who wants to buy one of those separately, will be able to do so. They won't need to own The Orchestra.
But The Orchestra Complete will continue to grow. There will be more instruments and more articulations, and probably more world instruments.
@Ashermusic Knowing the way Sonuscore monitors customer feedback, I am sure that there will be an English Horn in a future library. In fact, I think if enough people campaign online for any missing orchestral instrument, it's likely to be added.
