The Yamaha YDP-160/140 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."
The AWM (Advanced Wave Memory) is a sampling system which creates sound close to that of an acoustic instru-
ment by using digital technology to record the instrument sound and applying high-quality digital ﬁlter technology
to the recorded audio samples.
The waveform of the sound created by playing the key of an acoustic piano differs depending on the playing
strength from pianissimo to fortissimo. The AWM Dynamic Stereo Sampling can produce such dynamic nuances by
recording samples of various playing strengths. The greater the number of samples used, the higher the expressive
quality and potential becomes.
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 "Grand Piano 1" voice features multiple wave samples for different velocities (Dynamic Sampling); that is, dif-
ferent samples are used depending on how fast or strong you strike the keys. Therefore, this voice expresses detailed
dynamics and sounds much closer to a true acoustic piano.

A special Graded Hammer keyboard on the YDP-160, and Graded Hammer Standard keyboard with matte black
keytops on the YDP-140, feature graded key weight and response throughout the keyboard range. They respond to a
heavier touch in the low range of the keyboard and a lighter touch in the higher range of the keyboard, thus provid-
ing natural grand-piano type playability. The matte ﬁnish of the black keys enhances keyboard's luxurious appear-
ance. The Graded Hammer keyboard also offers superb playability for tremolo and other repetitive-striking
