Features Features AWM Dynamic Stereo Sampling 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 instrument 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, different 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. GH(Graded Hammer) keyboard and GHS(Graded Hammer Standard) keyboard with matte black keytops 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 providing natural grand-piano type playability. The matte finish of the black keys enhances keyboard's luxurious appearance. The Graded Hammer keyboard also offers superb playability for tremolo and other repetitive-striking techniques. 8 YDP-160/140 Owner's Manual 6
