whilst this is true (yamaha producing home keyboards) features like SA voices are definitely not meant for regular, home player...
it would take lots and lots of time to master the tehnique for playing these sounds at their full potential. what home keyboardist would do that?! and only for home (friends, family) performance?
whoever buys a T2, does it also for those advanced voices... that one must be a little bit more than a home-player.
