The Yamaha PSR-S650 boasts an enhanced Style performance engine with MegaVoice technology for ultra-realistic instrumental Style backing -- especially with guitar sounds. It also features Voice Expansion to load additional Audio Samples, Voices, Drum Kits and Styles to expand your creative possibilities.

MegaVoice Technology

Drawing on technology of the famous Tyros series, MegaVoice technology brings a greater level of realism to the Yamaha 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!

Wide Selection of Voices and Styles

The Yamaha 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.

Voice Expandability

The Yamaha PSR-S650 includes a 16MB FlashROM for storing additional Audio Samples, Voices, Drum Kits and Styles. Once data is loaded into the FlashROM, it's always available even if you turn the power off. This is a great way to add your own palette of musical colors… read more to the PSR-S650.
