61 regular-sized touch sensitive keys and 32-note polyphony.

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!

Cool! Voices reproduce the subtlest shades of the original sound of electric instruments. Sweet! Voices provide delicate nuances, such as the vibrato of wind and brass instruments.

Two assignable knobs on the panel give you flexible, powerful real-time control of filter (Voice or Style), effect settings, sound envelope (Attack and Release) and style tempo.

Tap into instant musical inspiration with the Arpeggio function! It provides 50 different Arpeggio types that automatically generate useful patterns and phrases that change depending on the notes and chords you play.

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 from a computer or stored on a USB flash memory device. These files can be used in the same way as the internal Music Database.

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.

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.
