Sorry if this is a dumb question, but I haven't looked into the software/technical side of Vocaloid for awhile. As far as I know if you want to use the V4X English voice banks for Rin/Len you first have to purchase the Japanese V4X voice banks and then use a download code to get the English voicebanks. What I was wondering is that since Crypton stopped supporting Vocaloid to focus on Piapro studio would these codes still work for Vocaloid? Also would buying a used copy have any effect on the code?
