Adjustable touch sensitivity allows customization to suit any playing style, and adjustable hammer response accurately reproduces the delay between when the key is struck and a note is produced. The PX-770 includes a powerful stereo amplification system. The speakers are conveniently located for an optimal listening experience, and are crystal-Clear across the entire audio spectrum. The PX-770s convenient features are useful at home, in a lesson studio, or anywhere else. You can connect two sets of headphones using the ¼ jacks on the front panel, making the PX-770 ideal for quiet practice. Duet Mode splits the piano into two equal pitch ranges, allowing a student and teacher to sit at the same instrument. 60 songs are included in the built-in Music Library, with room for ten additional songs of your choice. You can also record your performances using the PX-770s two-track MIDI recorder. Concert Play allows you to play along with ten recordings of well-known orchestral pieces, with the ability to either listen to the piano part or silence it so you can play it yourself. To facilitate practice, you can even slow down these recordings without affecting their pitch. Designed to compliment any décor, the PX-770 is available in either a black, walnut, or White finish. Its compact, elegant cabinet with sliding key cover adds to the beauty of any room.
