The build of the Pa4X is really excellent. The body of the keyboard is slim, much smaller than the Tyros 5. The metal
frame is really nice and for me the black finish is perfect.

The keybed is as good as they make and compares with the T5
for smoothness and quietness. I wish that Yamaha would slim
their boards. The Korg Pa4X will fit a cars smaller interior,
a plus as some Tyros 5 owners had to return their 76 note boards
for a 6l note board due to the bulk of the Yammy.
Sound wise I consider the Korg excellent although I did fancy
the Tyros5 accomps. Both are great keyboards. (I owned a T-5
so I feel qualified to say what I have. Lloyd
