It has its own 10- song, 6-track sequencer, as well as a USB TO DEVICE terminal for rapid, convenient storage of songs, styles, and Registration Memory data. Meanwhile, a pair of knob-type controllers provides for more-expressive live performances—for example, they can be used for real-time control of assigned effects such as filters or to modify Arpeggio function patterns, of which 162 different types are included. Not only keyboard playing, but also DJ performances can be made much more dynamic and exciting using these controllers.
The PSR-I455 can replicate a diverse range of instruments and musical genres from countries and regions all over the world, not just India. As such, it is suitable for a great many different types of music.
