To anyone hedging on this one, I strongly suggest you try it. You will be surprised.

It has the sonic authenticity of the best sample-based e-piano instruments if you want that.

It has the customizability of Modartt/Pianoteq's e-piano models.

It is so very sensitive/expressive/playable. The dynamics and the tonality respond particularly well to velocity/touch.

It is well worth the upgrade from EP-4, particularly if you really play well — if piano is your primary instrument.
