Basically, every time I set the Harpsichord stop to A5, I can play my score in Sibelius with that stop. However, if I go back to one of the GPO Players to mess with something, whether it be with the Harpsichord or not, when I return to my score the stop plays as C6. Now, this isn't a big problem, but when you "tweak" as much as I do with the players, it gets a little tedious to have to go to the Harpsichord patch and press A5 each time.
My more serious problem is that C1 controls written into my Sibelius scores aren't controlling the volume at all. Every time I open GPO Studio, I have to re-set all my volumes for each individual patch using both the volume wheel and the mod wheel.
These may just be bugs with v1.2, as I don't remember them happening in the previous version, but if anyone can help out, that'd be great!
