The PX-160 also features newly developed string ensemble sounds. These rich stereo strings sound wonderful by themselves or layered with the PX-160's grand pianos, electric pianos, harpsichord and more. The electric pianos have also been updated providing some dynamic sounds derived from Casio's award winning PX-5S stage piano. The PX-160 provides split and layer capability allowing you to play bass in your left hand and have two layered tones in your right. Duet mode allows the keyboard to be split into two equal ranges, so the student and teacher can use the piano simultaneously. A two track recorder can even record and playback your practice and performances. The optional CS-67 stand puts the PX-160 at the proper height and the optional SP-33 pedal system provides the same 3 pedal functionality as a grand piano.
