Graded Hammer Standard (GHS) Keyboard with matte black keytops
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. This Graded Hammer technology also enables the instrument to provide authentic touch in a lightweight instrument.
Amazingly Realistic Sounds
Yamaha's highly acclaimed Sweet! and Cool! Voices deliver incredibly natural and dynamic sound. Use the Pitch Bend wheel, and hear these Voices--especially the Sax and Trumpet--truly come alive!
Live!, Cool! and Sweet! Voices
A huge palette of acoustic and electronically amplified instrument sounds. A blend of long, stereo and multi-layered samples is used to fully capture the natural presence, resonance, expression and vibrato of the real instrument.
Digital Signal Processor (DSP)
The DSP effect can be added to the Main and Dual Voices. These range from reverb-like ambience effects to distortion and other dynamic processing tools that le you enhance the sound, or completely transform it.
Easy Song Arranger
In addition to each song's default style, you can select any other style to play the song with the Easy Song Arranger feature. This means that you can play a song that is normally a ballad, for example, as a bossa nova, as a hip-hop tune, etc. You can create totally different arrangements by changing the style with which a song is played. You can also change the song's melody voice and the keyboard voice for a complete change of image.
Performance Assistant Technology (P.A.T.)
Play along with a song on the instrument's keyboard and produce a perfect performance every time ... even if you play wrong notes! All you have to do is play on the keyboard--alternately on the left- and right-hand ranges of the keyboard, for example--and you'll sound like a pro as long as you play in time with the music.
Music Database plus External Files
You want to play music in your favorite style, but you're not sure how to select the best voice and style for the type of music you want to play ... simply select the appropriate style from the Music Database. The panel settings will automatically be adjusted for the ideal combination of sounds and style! Furthermore, this instrument allows Music Database files transferred via the internet (http://services.music.yamaha.com/). These files can be used in the same way as the internal Music Database.
USB TO DEVICE Terminal
Insert a USB flash memory in the USB TO DEVICE terminal on the instrument. It would let you save or load the registered settings and user songs created on the instrument, as well as read data from the connected device.
USB TO HOST Terminal
Dive in and take advantage of the wide world of computer music software. Connections and setup are exceptionally easy, and you can play back your computer recorded parts with different instrument sounds - all from a single instrument.
Portable Grand Button
Playing piano is fast and easy with Yamaha's Portable Grand function. One dedicated button brings up a great sounding piano, stunningly rich and authentic in its sound as well as setting up the keyboard to play as a piano.
Easy Performance with Music Notation Display
When you play back a song, the corresponding score will be shown on the display as the song plays. This is a great way to learn how to read music. If the song contains lyric and chord data*, the lyrics and chords will also appear on the score display. * No lyrics or chords will appear on the display if the song does not contain the appropriate lyric and chord data.
Yamaha Education Suite (Y.E.S.)
Yamaha Education Suite (Y.E.S.) is an advanced set of helpful learning tools built into the instrument, letting you teach yourself how to play and perform. Y.E.S. helps you master a song with easy lesson steps. Each lesson can be done in isolation with either your left hand or right hand, or both.
Optional three pedals unit (LP-7A) sold separately
