Hi, I recently found that Yamaha has expansion packs. I was particularly interested in the Church Organ pack, however, Yamaha "says" the packs are not available for the S-710. Does anyone know if the file type would actually be usable in the S-710? I really like the organ tutti!! Very powerful. I have downloaded some of the organ voices available on PSRT, however still searching for the right ones. I know the Tyros 5 has an incredible organ array. I'm wondering if someone could direct me to those Tyros voices if they would work on the S-710? Sorry, lots of questions all at once. Thanks, TOM
