Dynamic Expression, Realistic Sound
Hand-crafted Pianos, High-quality Voices
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.
Layer upon Layer
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.
Ascension to Detail
If you close your eyes while playing a grand piano, you'll find its sound is
a bit more complicated than "note-on-noteoff." Yamaha has gone to
great lengths to capture these sonic artifacts in the P-155. These meticulous
efforts include recording a felt damper coming to rest on a vibrating string
when a note is released [Key Off Samples], or reproducing the sound of the open
strings that wash over your performance when using the damper pedal [Stereo
Sustain Samples and Damper Resonance].
A Touch Above
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.
Perfection Made Practical
As a full-featured digital piano, the P-155 gives you all you need for
practice, playing and performance. It has an internal high-power, two-channel
(12W + 12W) amplifier with high-performance speakers built-in-letting you and
your audience hear the authentic sounds in their full glory. Is your audience on
