It didn't get my attention....till the combo stuff..New York state of mind..and Tea for two....That did sound great,,,
The orchestral stuff is ok for a wow factor demo..but is overdone and not practical on stage (limited use..maybe)..
I prefer the same band combo for a more realistic approach on stage...it sounds less artificial..
Tomorrow, we will have a chance to play the Tyros4 against the Audya....then we will better understand what is what...
For me with the on line demos so far..I have mixed feelings about the sound...I hear a lot of the same Tyros3...but Yamaha has added a new dimension (vocal sounds), I look forward to see if they are as playable as what I am use to on that other board
