Windows 7, Finale 25, GPO4 (also posted on the Garritan side)

Before I upgrade to Finale 26 and GPO5, I would like to get better acquainted with what I have--sort of to get a running start... silly perhaps, but nonetheless... :-)

Hi all,

So, say I have a violin set to play back with GPO4 "Violin 1 Solo KS" and want to change it to "Violin 3 solo KS" somewhere in the score--just to change up the timbre, etc, and then back again. How can I do that?
I have tried "Utilities/Change Instrument..." but the list is limited, and does not show the Garritan choices.

On a similar note, I have just discovered the "Violins Lush Mutes" instrumentation in GPO4:
Is there a way to choose "mute" and then back to normal anywhere in the score for violin solo or section as one would change from arco to pizzicato?

Thank you!
:-)
