The PSR-SX900 features an FSB, 61-key keyboard that provides remarkable comfort and performance. The keyboard has heavier initial key resistance and excellent key travel. The piano has a refined keyboard structure that includes an adjusted fulcrum, which allows you to conveniently play the keys. There are also upgraded components that significantly suppress the horizontal key movement, and this contributes to great key performance.

The Joystick feature included in the piano also provides intuitive pitch and modulation control, which allows you to play rapid trills, finely nuanced modulation, and dynamic pitch blends, from just a single and well-configured controller. The 7-inch touch display and new graphic interface offer you full control over all the features of the piano. Additionally, you can easily activate all the functions or select from a wide range of functions. That means you can assign them to the 6 assignable buttons, pedals, the home shortcut menu, and the live control knobs. Once you’ve done that, you can then recall them with just a single touch.

What’s more, the keyboard includes 4 parts that deliver optimal performance. These four parts are; Left, Right 1, Right 2, and Right 3. When you combine these four keyboard parts, you’ll have the capability to create rich instrumental textures and enjoy the convenience of your performance.
