One of my fav topics! Regarding Yamaha, the Tyros has gotten WAY more support than the former "flagship" arranger, the 9000 Pro, ever did. Even when we did get OS upgrades, they were sometimes buggy. At least the Tyros came with voice editing software that we were promised for the 9000 Pro but was never delivered. But that's nothing compared to the lack of support and functionality I am experiencing currently with Yamaha/Zero-G's Vocaloids program, which really doesn't work as it should at all and upgrades just to provide normal VST functionality are not yet available.
