Yamaha DGX640 88-Key Portable Grand Piano Keyboard

Key Features

• Graded Hammer Standard (GHS) Keyboard with matte finish of black keys: 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
• Amazingly Realistic and Dynamic Sounds: Yamaha's highly acclaimed Sweet! and Cool. Voices deliver incredibly natural and very 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): 237 types of 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 let 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
• 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
• 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
• USB To Device: The USB TO DEVICE on the instrument allows you to connect USB memory devices such as flash drives or hard drives, enabling you to save or load registrations and user songs created on the instrument, as well as read data from the connected device such as MIDI files or style files
• USB To Host: 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
• Easy Performance with Music Notation Display: When you play back a song, the corresponding score will be shown on the display. 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
• 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
• Optional three-pedal unit (LP-7A): The pedal unit has three foot pedals that produce a range of expressive effects similar to those produced by the pedals on an acoustic piano
