The Casio CT-S500 delivers studio-quality sounds and features in an ultraportable, easy-to-use keyboard that is always ready to inspire. Smart and customizable, the CT-S500 is ready to bring your music to life at home, on stage, in the studio or anywhere else.

Take Control

The CT-S500 features 61 full-size touch-responsive keys in a sleek, stylish case that weighs less than 10 lb., with an easy-to-read LCD display and intuitive controls. Use the pitch bend wheel and modulation knob to add natural (or supernatural) expression to your playing—and use the two assignable knobs to tweak EQ, filter, effects and many other settings on the fly.

The Heart of a Champion

The AiX Sound Source delivers sound quality that you'd expect from a keyboard costing hundreds, if not thousands more. Power on the CT-S500, and you'll be presented with a dynamic, expressive German concert grand piano placed in a virtual concert hall. The collection of 800 tones has stellar examples of 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.

A World of Music to Explore

The 243 full-accompaniment rhythms in the CT-S500 make it a perfect jamming partner. Simply play a few notes, and it can create an entire backing band that reacts effortlessly to the way you play. No matter what kind of mood you're in, your Casiotone is always ready to back you up with vibrant acoustic drums, vintage drum machines, global percussion instruments, rock-solid basslines, horn ensembles, rhythm guitars and much more.

Free Play Enabled

The CT-S500 fits perfectly into your everyday life. It’s also gig-ready, with 1/4" line outputs to connect to amps and PA systems. If you're tired of being tied down, just put in six AA batteries, attach a strap and play anywhere. Use the included WU-BT10 Bluetooth MIDI/audio adapter to control other gear remotely, giving you the freedom to take center stage.

Own Your Sound

The CT-S500 makes it easy to create your own signature sounds. You can layer, split and customize the versatile DSP effects, then save your setups as registrations for easy recall at the touch of a button.

Small Size, Huge Sound

There are four ways to experience the CT-S500'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, connect the 1/4" line outputs to any amplifier, PA system or mixer. Fourth, push the SURROUND button, and the speakers will place you right in the middle of your music.

Production Power

Make the world your instrument by using the built-in audio sampler to create custom tones and drum kits. A 6-track sequencer is always on hand to capture and build your creations.

Connected to Your World

The microUSB port connects your CT-S500 to any PC, Mac, iOS or Android device with no drivers or installation needed. Use the free Casio Music Space app for iOS/Android to learn to learn MIDI songs, play and extract chords from audio files, view PDF scores and more.

With the included 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-S500 as a Bluetooth speaker.
