Enjoy new levels of expression and performance with a phenomenal new velocity-switched stereo piano sound, matched to our exceptional graded hammer action RH3 keyboard. The SP-250 is the first Korg digital piano to feature the all new RH3 real weighted hammer action. This state-of-the-art key mechanism features differing key weights in each register of the keyboard, delivering the same playing experience as a grand piano. The keyboard is exceptionally responsive, even when playing quickly repeated figures, to preserve every expressive nuance of the performer. The Key Touch Control provides three selectable touch curves, delivering the perfect touch sensitivity for every playing style or type of song. Yet even with such a robust keyboard, the SP-250 weighs less than 42 pounds (19 kg.). Thirty built-in sounds, including twelve types of piano and electric piano. Also features jazz and church organs, mallets, harpsichord/clav, choir, strings, and guitar sounds.
