Sorry for so basic a question, but I’m new at this aspect of things:
In Using Expression Maps in Dorico | Play Mode in Dorico - YouTube, Anthony Hughes demonstrates how to use expression maps.
At one point, he shows how to create a new expression map for an instrument from his East-West sample library, but then he does something that I don’t understand: at Using Expression Maps in Dorico | Play Mode in Dorico - YouTube, he loads a VST named “Play”, and directs that “Play” VST to use his East-West expression map.
Why did he not simply name the new VST “East-West”? And why “Play”?
