Yamaha YDP142R Arius Series Traditional Console Digital Piano with Bench, Rosewood (OLD MODEL) Graded Hammer Standard weighted action has a heavier touch in the low end and lighter touch in the high end, great for the aspiring pianist. Meticulously sampled from Yamaha's acclaimed CFIIIS concert grand, the Pure CF Sound Engine provides the tone of a 9' concert grand piano. Continuous or half-damper pedal control allows continuously increasing amounts of note sustain, from slight to full, as you depress the sustain pedal. Using a special design and position within the instrument, the Acoustic Optimizer physically adjusts the acoustical flow, which controls resonances and enriches the overall sound. Use the built-in, 2-track song recorder to practice one hand at a time or capture that next top-10 hit single!
