Whether you're practicing at home or away, performing solo or in a band, the Yamaha P-155 digital piano offers professional quality sound with our legendary piano touch. Thanks to the top-shelf Yamaha digital piano technologies like advanced sampling methods and the ultra-expressive GH (Graded Hammer) keyboard, musicians don't have to choose between portability and piano quality—the quality you expect from a company that's been building world-class acoustic pianos for over a century.
To ensure the finest grand piano sound for the P-155, we went straight to the source: Yamaha's finest 9-foot concert grand, a hand-picked CFIIIS. Next, a master piano technician painstakingly tuned and regulated the CFIIIS to sonic perfection. Then we applied our Pure CF Sampling technology to accurately capture every aspect of the CFIIIS sound, keeping post-processing to an absolute minimum to maintain sonic integrity throughout. The result is a truly authentic grand piano sound with powerful, dynamic bass, warm mid-range and crystal-clear highs.
Using Yamaha's Dynamic Stereo Sampling (DSS) technology, the incredibly natural 4-level piano sample is a breakthrough achievement for digital pianos. It means that, depending on how hard you strike a note, you will hear one of four piano recordings on each and every key for an unprecedented level of dynamic range and tonal expression. Playing softly doesn't simply lower the volume; it produces the quiet recordings of piano notes. And likewise, playing more forcefully triggers separate samples at different levels.
Look inside the lid of a grand piano. Different sized strings require different sized hammers. Different sized hammers have different weights. The keyboard of the P-155 utilizes Yamaha's GH (Graded Hammer) technology to reproduce the true "feel" of a grand piano keyboard action, with heavier touch in the lower keys, lighter touch in the higher keys, and subtle gradations of weight and response throughout. Thanks to the input of concert-level, professional pianists during its development, the GH keyboard features superb balance and remarkable consistency. Performing or practicing on a GH keyboard properly develops and maintains an artist's technique for making the transition between P-155 and an acoustic grand.
