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-S400, and you'll be presented with a dynamic, expressive German concert grand piano placed in a virtual concert hall. Inside the collection of 600 Tones, you'll also find great-sounding electric pianos, organs, strings, synths, and more.
A World of Music to Explore

The CT-S400's 200 full-accompaniment Rhythms make it a perfect jamming partner. Simply play a few notes, and it will 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 so much more.
Small Size, Huge Sound

There are three ways to experience the CT-S400's amazing sound quality at its best. First, the bass-ported speaker system delivers punch and clarity throughout the entire volume range. Second, plug in a good set of headphones for personal play. Third, turn on SURROUND, and the sound from the speakers will place you right in the middle of your music.
Take It To Go

With a CT-S400, there’s no reason to feel tied down. Just pop in 6 AA batteries, attach a strap, and wherever you are becomes center stage
Connected to Your World

The microUSB port connects your CT-S400 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-S400 as a Bluetooth speaker.
