About Casio CT-S1 OB

Take your musical journey to new heights with the Casiotone CT-S1 61-Key Piano Style Portable Keyboard in sleek black. This modern-day marvel, inspired by the original 1980 Casiotone CT-201, is designed to make music accessible to everyone, regardless of skill level or budget.

The CT-S1 is not just a keyboard; it's a personal statement. Choose the color that best complements your style and personality. With 61 studio-quality, stage-ready tones at your fingertips, you can express your musical creativity in a myriad of ways. Its ultra-portable design, powered by 6 AA batteries, allows you to transform any space into your personal concert stage.

Like its Privia and Celviano digital piano counterparts, the CT-S1 boasts a streamlined design with simplified controls. This allows you to focus on selecting a tone and practicing or performing without distraction. It also features a handy metronome button to keep your rhythm in check and a one-button recorder to capture your musical ideas instantly.

At the heart of the CT-S1 is the AiX Sound Source, delivering sound quality that rivals keyboards costing significantly more. From the dynamic, expressive German concert grand piano to electric pianos, organs, strings, synths, and more, the CT-S1 offers a rich variety of sounds. It also includes a collection of vintage keyboard sounds and classic Casio sounds from the VL, VZ, and CZ series.

Experience the CT-S1's amazing sound quality in three ways: through the bass-ported stereo speaker system for punchy, clear sound; by plugging in headphones for personal play; or by pressing the SURROUND button for an immersive musical experience.

The CT-S1 is more than a keyboard; it's a gateway to a world of musical possibilities. From choosing virtual concert venues to layering tones, adjusting temperaments, and more, the FUNCTION button unlocks the CT-S1's full potential.

Stay connected with the micro USB port that links your CT-S1 to any PC, Mac, iOS, or Android device without the need for drivers or installation. Use the free Chordana Play app to learn to play your favorite songs with downloadable MIDI files. With the optional WU-BT10 Bluetooth MIDI/audio adapter, you can even connect wirelessly to your favorite devices, or use the CT-S1 as a Bluetooth speaker.

In essence, the Casiotone CT-S1 61-Key Piano Style Portable Keyboard is a compact, stylish, and versatile musical companion that caters to both beginners and seasoned players.
