The C1 is a truly exceptional digital piano. With KORG’s unique history of musical instrument design and audio technology, the C1 offers levels of playability and versatility that will exceed the expectations of the most demanding pianist.
The KORG C1 digital piano features a Real Weighted Hammer Action (RH3) keyboard that divides the hammers into four different weights, with a heavier feel in the low register and a lighter feel in the high register as found on concert grand pianos. Key touch control is also provided, with a choice of five levels of sensitivity (light, normal, heavy, stable, fixed) to specify how your playing dynamics are reflected by the sound produced.
C1 Air has 120-part polyphony and 30 built-in sounds. Among of them are sound of Japanese and German concert grand piano, which were chosen to reflect a broad musical spectrum providing faithful recreations of dark, subtle and intense classical music through to bright and powerful jazz and pop music. Additional voices are electrodiano, organ, clavinet, acoustic guitar and other instruments.
Both the German Grand Piano and the Japanese Grand Piano sounds realistically recreate the "damper resonance" effect produced by the sympathetic resonance of the strings in an acoustic piano when the damper pedal is held down.
You also get three high quality effects to play around with too—namely brilliance, reverb, and chorus. These settings are especially great because, with something like brilliance, you can make the sound mellow or soft, and ultimately can bring it up to a much more brighter sound depending on how hard you go about hitting the key.
Connect a Bluetooth device such as a smartphone to the C1 Air and enjoy playing the piano along with your stored music or other audio. When you are not playing the piano, you can use the C1 Air as a powerful Bluetooth speaker system.
The 2 track recorded on Korg C1 Air will allow you to record your practice session and to help you analyze or archive your performances.
C1 is equipped with the full complement of three pedals found on a grand piano: damper, soft and sostenuto. The damper and soft pedals also feature half-pedaling for even more detailed expression.
