CT-S1BK portable keyboard In 1980, the original Casiotone CT-201 allowed anyone to make music, regardless of skill level or budget. With the CT-S1, its spiritual successor, we've raised our own bar. The Casiotone CT-S1 is a great-sounding, stylish, ultra-portable keyboard designed for anyone to enjoy playing. Its incredible sound quality makes it an ideal musical partner for beginners and seasoned players alike, and its sleek, portable design makes it fun to play anytime, anywhere. Now It's Personal The CT-S1 reflects your style in more ways than one. Choose the color that best matches your home, your look, or your life in general. Then, express yourself with 61 studio-quality, stage-ready Tones. And with a keyboard that looks and sounds this good, there's no need to keep it on a stand. Put in 6 AA batteries, attach a strap, and wherever you're standing becomes center stage. Basically Everything Like many of our Privia and Celviano digital pianos, the CT-S1's streamlined design features simplified controls that allow you to focus on selecting a Tone and practicing or performing without distraction. A convenient metronome button helps you keep time, and an easy one-button recorder lets you capture ideas. The Heart of a Champion The CT-S1's AiX Sound Source delivers sound quality that you'd expect from a keyboard costing hundreds, if not thousands more. Power on theCT-S1, and you'll be presented with a dynamic, expressive German concert grand piano placed in a virtual concert hall. You'll also find essentials like electric pianos, organs, strings, synths, and more, with Advanced Tones adding complex layers that react to your playing. A collection of vintage keyboard sounds is also included, featuring recreations of timeless, sought-after keyboard instruments. We've even included classic Casio sounds from our VL, VZ and CZ series. Small Size, Huge Sound There are three ways to experience the CT-S1's amazing sound quality at its best. First, the bass-ported stereo speaker system delivers eyebrow-raising punch and clarity throughout the entire volume range. Second, plug in a good set of headphones for personal play. Third, press the SURROUND button, and the sound from the speakers will place you right in the middle of your music. More Than Meets the Ears A world of possibility lies behind these keys. You can choose virtual concert venues, layer tones together, add delay and EQ, adjust temperaments, and much more, right from the front panel. The FUNCTION button takes you far beyond the ordinary, and every CT-S1 comes with an easy guide that shows you exactly how to unlock the CT-S1'sfull potential.
