Digital piano featuring GHS keyboard and Yamaha CFX concert grand piano sample. The ARIUS YDP-144 is an affordable digital piano, perfect for students or hobbyists looking for an attractive instrument for their home. Newly sampled for the YDP-144, the Yamaha flagship 9' CFX concert grand piano offers sparkling highs and a powerful resonant bass combined in a sound that projects to the furthest reaches of any concert hall. With an 88-key piano action, the Graded Hammer Standard (GHS) keyboard reproduces the touch of an acoustic piano, from the heavy feel in the lower register to a lighter touch in the upper octaves. With matte black keytops, the touch and feel of this keyboard action makes it comfortable to play for hours on end. The YDP-144 offers convenient functions for when you cannot always play the piano at high volume. Intelligent Acoustic Control (IAC) adjusts the sound automatically to allow players to enjoy balanced sound at any volume level. Stereophonic Optimizer lets players enjoy the natural, spacious sound experienced when sitting in front of an acoustic piano, even when wearing headphones.
