After re-visiting the above demos...I believe the Tyros4, improved the drums (at least the brush kit)...The drums have always been dead last in the competition, but the Tyros4 is presentable...

The problem for me..is still there...after listening again to the above demos.....Yamaha still sounds like they are heard down the hall or in another room...I just dislike this....Listen to the Korg and other demos presented...doesn't bother anyone...be honest ..for a change ...Just listen..
