The sounds really seem to be a mixed bag. I heard a wonderful realistic, wooden Steinway piano sample among the Deebach Soundcloud demos, nothing remotely comparable in the Tyros 5. (Of course I don't know whether that would be available in this new arranger.) On the other hand, e.g. some saxophones seem a lot worse than the Korg saxophones I know from the Krome and M3.
