CK turns everywhere you go into a stage or studio with intuitive controls, built-in speakers, and all the sounds you need to create your own sound.

Pianos, electric pianos, strings, brass, organ and modern synth. Easy-to-use controls let you focus on the music, not the menu. Dedicated organ controls and Synth and Effect controls. It's all battery powered and has built-in speakers to take your music where it's never been before. Everywhere.
