Enjoy the outstanding AWM stereo reproductions of instruments such as a Yamaha grand piano, reproduced through newly developed speakers with rich harmonic detail, making every musical endeavor, whether practicing or performing, a truly inspiring experience. Authentic playing feel of an acoustic piano and control over the half-damper pedal. With an 88-key piano action, the GHS (Graded Hammer Standard) keyboard reproduces the playing feel of an acoustic piano, from a naturally heavy feel in the lower keys to a lighter feel in the upper octaves. The GHS keyboard offers a response and feel like a grand piano, enabling rapid note repetition and authentic expressive control. In addition, there is a half-damper function that authentically replicates the damper mechanism of a grand piano, thus offering rich expressive variations. Reproduction of the resonance of an acoustic piano. Damper resonance reproduces the broad, deep sound field of an acoustic piano. It also reflects the tonal changes that occur when a grand piano's damper pedal is pressed. It includes sounds such as those emanating from the keyboard and emulates the cumulative resonance that occurs when all these sounds blend together. Enjoy built-in songs, intuitive operation, and score display with the Smart Pianist app. The YDP-105 offers an authentic grand piano sound, as well as other built-in instrument sounds, including electric piano, organ, vibraphone, and strings—a total of 10 voices—and 10 famous built-in classical songs. The YDP-105 is also compatible with Yamaha's free Smart Pianist app. Simply download the app to your smart device and connect it to the instrument. The Smart Pianist app allows for easy operation of the instrument's various voice functions and simplifies the retrieval of different notes, including those of the built-in songs.
