Perfect for beginning students and experienced players alike, the ARIUS / YDP series provides true piano sound and feel. The Graded Hammer keyboards of the YDP-160 and the Graded Hammer Standard keyboard of the YDP-140/S31 make it a true joy to play, both in practice and in performance. The AWM Stereo Sampling voices deliver remarkably authentic sound. Moreover, the damper pedal includes a half-damper effect, giving you nuanced expressive control over the sustained sound. Dual voice capability lets you play two different instrument sounds at the same time, while a 1-track song recorder allows you to capture your original musical ideas and performances.
