Hi All

I take advantage of this good forum to try to find something difficult on music market .
Since I own a GS3 Orchestra and I would like upgrade to GS4 to continue and better use function like imidi legato with the Vienna Sympnonic Library GS format . I ask if someone can sell me a GS4 upgrade.

I have tried to contact a lot of internet shop but noone of these have it anymore.

Thank you in advance for the help.
