The instrument has been designed in a perfect way. The possibility of quick editing of zones with appropriately assigned colors is simply brilliant. The keys work as they should and the whole is complemented by a built-in mixer for the above zones and connected inputs. I have the impression that the piano sounds differ from what can be heard on the manufacturer's website, or maybe it is a matter of settings in the instrument itself. I also had a problem with the damper pedal a few times, which sometimes did not work properly or did not work at all. I had to turn the instrument off and on then, and once only a reset of the instrument to factory settings helped. Nevertheless, I am VERY pleased.
