I have Gigastudio 3.0 orchestra but don't use it.... honestly because I am too busy with other matters to learn it (I could have used a video, but even so.) I am very fluent in Finale and to some extent use GPO and JABB with Finale, which is not so hard because they "plug in" to Finale.
I don't exactly understand the advantage or disadvantage to GVI. Tell, me, if I upgrade to GVI does GVI then work like GPO and plug into Finale? That is, I open Finale and in the midi setup select GVI? Or is there more to it than that?
