Second Hand Yamaha YDP131 digital piano

GHS Keyboard. The Yamaha YDP-131 digital piano features a special “GHS (Graded Hammer Standard)” keyboard that offers natural grand-piano type playability. This keyboard adheres to the basic principle of the “Graded Hammer” keyboard, which was developed through extensive research for the best grand piano sound, while providing a weighted keyboard response that is graduated from the low range to the high range (i.e., lower keys are weighted more heavily). As a result, the YDP-131 provides unmatched sonic realism and natural grand-piano type playability.

AWM Stereo Sampling. The sound source of the YDP-131 uses Yamaha’s original “AWM Stereo Sampling” tone-generation technology for rich and musical voices. Two of the piano voices, “Grand Piano 1” and “Grand Piano 2,” feature totally new samples recorded from a full-size concert grand piano. The “Electric Piano” voice features multiple samples for different velocities (Dynamic Sampling); that is, different samples are used depending on how fast or strong you strike the keys. This digital piano sounds much closer to a true acoustic piano.
