The MZ X500 excel in piano's, e-piano's, bass, organ and synth sounds. I really like these sounds especially the hex layer sounds but is this worth 1000 euro? I don't know yet but I am still interested in this casio.
Where it comes to piano, the mz-x falls short of the real Casio DP..
I think the guitar sounds are atleast very decent
And the string sounds are actually quite good from this video..
And all the other sounds, and acompanying styles i havent heared demoed...
