Gary I understand that scientifically there may be stronger plastic than metal somewhere out in the universe but I highly doubt Yamaha re using that substance in their tyros / genos products.

Why is it hat all High end / pro instruments use metal casing and plastic is only used for the mid range and lower end?

Im sure anyone here would agree that as soon as you lay your hands on a keyboard that has metal casing you instantly have that "quality" feeling that this is something special... U get it with the Motif series, the Montage, the Korg PA 3x/4X, Ketron units, but not with PSR's or Tyros keyboards...

When you look at a keyboard that is made from metal you just know its a more "serious" thing before even turning it on.

people are happy to settle for plastic made keyboards if it does the right thing, which is what many folks have done with the Tyros / PSR and mid range Korg and roland units. And there absolutely nothing wrong with that.. but when you step up to the next level and fork out the extra money for the top of the line.. you dont want to see plastic...
