Casio CT-S1 Portable Electronic Keyboard

This under-10-pound, battery-powerable board gives you 61 full-size keys, dozens of inspiring sounds, and strap pins so you can sling it on and jam anywhere!

The Casio 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 Casio's 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 the CT-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. Casio even included classic sounds from their 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 read more 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's full potential.

Connected to Your World

The microUSB port connects your CT-S1 to any PC, Mac, iOS or Android device with no drivers or installation needed. 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 to control them via MIDI, or to use the CT-S1 as a Bluetooth speaker.
