The CLP-635 is where the CLP lineup starts to re-define what to expect from a digital piano. The re-designed interface lets you browse the 36 high-quality instrument Voices with ease. Choose from two world-class concert grand pianos, the Yamaha CFX and the Bösendorfer Imperial. New to the CLP-600 series, you'll experience the sound of the binaurally sampled Yamaha CFX through your headphones. You can enjoy the realism of Virtual Resonance Modeling, and high-quality digital effects through the on-board stereo speaker system. Play along with built-in rhythm patterns and record your performances using the built-in USB audio recorder. And with over a century of acoustic piano manufacturing heritage, it only makes sense that the best digital pianos come from Yamaha.
