The PSR-EW310 has everything you need in a starter keyboard, with 76 keys for the more serious piano beginner. With USB to HOST audio and MIDI connectivity, it’s easy to expand the capabilities of your instrument by interfacing with creative or educational apps on your iOS device or computer. 11 Super Articulation Lite Voices (SALite), inherited from the powerful PSR-S models, are now included. These give you even greater expressive, real-time control (e.g. String Scratches/Guitar Slide noise), adding to the realism of the Voice. The Super Articulation Lite Voices can be controlled with the “Art” button to intuitively reproduce the natural expressive nuances of non-keyboard instruments, allowing keyboard players to achieve realistic expression.
