I have had many digital pianos. For the last 10 years I had a Korg. I found this affordably priced Kurzweil and had to have it. The realistic sounds and percussion are great, Although I do not use the preprogramed percussion rifts, they are there if you do. I did not like the the lack of a user manual to describe how to access and use the features. I figured them out eventually but it would have been helpful to read it. Overall it sounds beautiful. I especially like to use the 51 preprogramed classical tunes as a jukebox and just let it play for dinner guests.
