I’ve downloaded the GPO4 Expression Maps from the Steinberg web site. They include only strings. My understanding is that the woodwind and brass instruments in GPO all have expression parameters assigned in the Aria player. Does anybody know where to find maps for them, as well?
If the articulations are somewhat alike, maybe you can edit the string maps to correspond? And post these maps for the world to have? %)
I found out they already exist. They are installed in the Program Files\Garritan directory when the library is installed.
