Main Features

Graded Hammer Effect Keyboard
Thanks to our experience as the world's leading manufacturer of acoustic pianos, we've developed a keyboard with
action that's virtually indistinguishable from the real thing. Just as on a traditional acoustic piano, the keys of the lower
notes have a heavier touch, while the higher ones are more responsive to lighter playing. The keyboard's sensitivity can
even be adjusted to match your playing style.
AWM Dynamic Stereo Sampling
This digital piano offers a rich and versatile range of sounds, which are created using Yamaha's proprietary sampling
tone-generation system, "AWM Dynamic Stereo Sampling."
AWM (Advanced Wave Memory) is a sampling system that creates sounds close to those of an acoustic instrument by
digitally recording the sounds of an instrument and applying high-quality digital filtering technology to the recorded
audio samples.
The sound waveform created by an acoustic piano differs depending on the player's strength of touch, from pianissimo
to fortissimo.
AWM Dynamic Stereo Sampling can create extremely dynamic nuances by recording samples at various playing
strengths. The greater the number of samples used, the greater the resulting expressiveness of the instrument.
The piano voice "Grand Piano 1" features a totally new sample recorded from a full-size concert grand piano. Each
note in the sample has been adjusted meticulously so that the digital piano will play only the very best piano sounds.
The piano voices are well-separated sounds featuring a fast attack and a satisfying response.
The "Grand Piano 1" voice features multiple wave samples for different velocities (Dynamic Sampling). That is, differ-
ent samples are used depending on how fast or strong the player strikes the keys. Therefore, this voice expresses
detailed dynamics and sounds much closer to those of a true acoustic piano.
The instrument creates a rich, luxurious sound using "Sustain Sampling," which is a sample of the soundboard and the
resonance of the strings when the damper pedal is pressed. The instrument also features "Key-off Sampling," which is a
sample of the very delicate noises that are caused when keys are released.
