I am working with full GPO and Garritan Studio, no HP.
It´s not possible to make piano pedaling since CC#64 control the legato.
In Finales Plug-In menu thera are a plug-in called Playback>Apply Human Playback.
There you can choose Pedal Marking.
Is it possible to use that for pianostaff only and how does one do that?

Or is there another trick to make it work? (Remember reading something about it).
