For use with other musicians and vocalists there is a devoted mic/guitar input port, the sound of playing or singing is then run through the PSR-S770 and can be treated using the many effects. A USB audio playback feature also allows tracks to be played through the instrument and altered with time stretch, pitch shift, vocal cancel effects.

The 360 pre-set accompaniment styles follow notes as they are played on the keyboard and expand the music to include all the elements of a full band in almost every conceivable musical genre.  

But the PSR-S770 isn’t limited to these parameters, with a massive 130MB storage and easy connectivity to databases both voice and style sets can be updated with brand new sounds.
