dear musician friend, i have a psr s970 i am from argentina and i intend to get in ppf the selecao brasileira, southeast europe, and celtic packs, since my goal is to get the one that i can buy from the sx series that follows, not the one 900 because it is unpayable in my country, but if at least the replacement of the 600 and I know that all of the 970 work in the new ones, thanks for your attention God bless you
