"A Tyros 3 is twice as good as Tyros 2 because they have doubled the amount of wave memory found in Tyros 2. Wave memory is what creates the sound and if this is doubled then every sound will sound twice as good."

I only had to read this to understand that the writer does not know what they are talking about. Double wave memory does not equate to twice as good a sound.

But i will wait and try one myself
