Thanks to Yamaha’s new Voice & Style Expansion contents for the PSR, players can take advantage of a wide and ever-increasing selection of regional, ethnic and traditional Voices and Styles. Load them to your PSR and instantly play authentic sounds, rhythm and backing in the musical style of your choice!

Drawing on technology of the famous Tyros series, MegaVoice technology brings a new level of realism to the PSR-S650. The MegaVoices feature various playing articulations, techniques and performance sounds.
For example, guitar MegaVoices can have hammer-on, slide and mute sounds to go along with soft, medium and loud sounds with strumming and fret noise, all at the same time. Put it all together in a Yamaha Guitar-Enhanced Style and enjoy some of the most astonishingly realistic, expressive accompaniment you've ever heard!

The PSR-S650 provides an exceptionally wide variety of realistic sounding Voices in all instrument categories. With a total of 359 amazingly authentic instrument Voices (including 9 MegaVoices), and 181 accompaniment Styles, you can enjoy regionally unique music—and have more fun.

You can configure the tuning of the keyboard to match the music you're playing, with one of the nine preset custom tunings, like Arabic or Pythagorean - or by creating your own!
