I think it's nice to see that some of the things Yamaha added to the Tyros line this time round are FINALLY things the better player or full time pro can appreciate! Primarily, the return of a 76 option for those that actually CAN play a piano, and then the dual sequencer/MP3 player for those that need DJ style non-stop music...
But yes, Charles' post can basically be said for ANY keyboard. If you aren't as good a player as the demonstrator, you are NEVER going to sound as good. But advice such as his is always wasted here. This is the last place on earth where anyone seems to care about being a better MUSICIAN... Most seem to have drunk the Kool-Aid and think that the gear alone is going to achieve that!
And when it doesn't, they are convinced the NEXT model will do the trick...
