Although the CGP-700 is loaded with impressive features, it?s also incredibly easy to use. The centerpiece of the CGP-700 is a beautiful 5.3? Color Touch Interface?. This high-resolution display is bright and clear, and makes full use of a huge color palette to keep you informed and in control. Navigating through tones and rhythms using touch and swipe gestures is a breeze. There?s also a handy Grand Piano button, which lets you enjoy the CGP-700?s brilliant grand piano sound instantly, and nearby Transpose buttons allow you to quickly shift to a different key.
