The slim, compact CDP-S160 from Casio is realistic, portable and comfortable to play. It's an ideal choice for students, hobbyists or pianists who crave grand piano sound and feel in a small space. The CDP-S160 delivers natural piano sound and can run on either its included power supply or six AA batteries. Enjoy a realistic piano touch with the CDP-S160’s 88-key scaled hammer action keyboard. Simulated ivory and ebony key surfaces prevent slippage as you play. Duet mode is ideal for lessons or performances, allowing two people play the same range of keys on a single CDP-S160. Controls include a one-button recorder that can capture and play back your performances.
