Just choose a song and the keys become your guiding lights, with intuitive Step- Up Lessons to help you along. With the free Casio Music Space app for iOS/Android, you can also learn to play any MIDI file using standard notation, a "piano hero"- style display, or both.

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 LK-S450, 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 much more.

A World of Music to Explore

The LK-S450'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 musical 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 LK-S450'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 LK-S450 to any PC, Mac, iOS or Android device with no drivers or installation needed.
