With a full range of 88 keys that are exactly the same size and weight as a traditional piano, the CDP-120 will suit students of all ages and abilities. The piano has its own built-in stereo speakers and can also be played through headphones or a separate PA system. Adjustable digital reverb and chorus effects are also included and the piano connects easily to a computer or tablet via its USB interface. The CDP-120 has a Scaled Hammer Action keyboard that recreates the feel of an acoustic piano in great detail. The sensitivity of the keys can be adjusted to accommodate tiny fingers or those with injuries that cannot press the keys firmly.
