Feel at One with the Music
Casiotone Today – A Perfect Combination of Tradition and Technology
The next generation of Casiotone is the product of 40+ years of experience and
technological development since we created our first electronic musical instrument.
They’ve been given a modern overhaul while staying true to our philosophy
of creating musical instruments accessible to anyone.
Express Yourself Like Never Before with Aix Sound Source
Casio’s state-of-the-art AiX Sound Source technology delivers stunning depth and realism through the complementary design of circuits, mechanical build, software, LSI processors and other components, providing extraordinary sound from a remarkably compact keyboard. Based on in-depth analyses of the audio characteristics of different instruments, AiX Sound Source can accurately reproduce acoustic instruments such as pianos and strings, electric instruments such as electric guitars and organs, and the electronic sounds of synthesizers. Tap into the unique expressiveness of each instrument and let your imagination inspire your performance.
Custom LSI Processor Vividly Capture Subtle Nuances
To achieve this refined expressiveness, Casio has developed proprietary large-scale integrated (LSI) processors, which are an integral part of the new Casiotone. The high-performance custom LSI chips are efficiently designed for optimal sound expression, and the unique waveform compression technology makes rich, high-definition sound a reality. For example, not only are the source instruments painstakingly recorded to reflect the nuance of the performance, but the LSI chips can also model the characteristics of amplifiers found in vintage instruments. This is possible through high-speed processing of the considerable data amassed from these original vintage instruments, enabling a superbly realistic response to musicians’ performances.
Distinctive Tones Expand the Possibilities of Expression
Rich, Exultant Tones, Created Through a Relentless Pursuit of Excellence
ADVANCED TONES – upper-echelon, refined Casio tones – are crafted using the best of Casio technology. Created by carefully modeling the acoustic and vintage instruments used in many classic songs, the tones come to life through AiX Sound Source. The result is a vivid recreation of the unique character and nuance of each instrument, with tones that vary dynamically in response to different subtleties in playing, enabling fresh new forms of expression.
* Only available on the CT-S1.

Powerful Acoustics from a Compact, Refined Structure
Innovative Bass-Reflex System Packs a Punch in a Compact Space
[Horizontal Bass-Reflex System]
The Horizontal Bass-Reflex System is a space-saving technology designed to produce powerful bass, even from slim-bodied instruments. Rather than being directly mounted to the upper housing, the speaker is mounted on a component attached to the lower housing, forming a dedicated enclosure (speaker box). Its solid structure enables the Bass-Reflex System to produce compelling bass while controlling distortion and sympathetic vibrations, while enclosure parts and screws that could obstruct air flow or result in sympathetic vibration were also carefully eliminated. The ducts are rounded, meaning that sounds generate less noise as they travel through them, and the bottom surface of the case is slightly raised to prevent bass tones from being trapped. The elliptical design of the speakers achieves a slimmer body with a larger surface area, while the two-stage magnet generates a stronger magnetic force. Also, the edges of the cones (diaphragms) are made from fabric for a crisp, clean sound.
Intelligent Sound Adjustment Ensures Big Sound, Even at Low Volumes
Volume-Sync EQ automatically corrects the balance between higher frequency sounds and the low register, which is subjectively quieter at low volumes. Optimizing the sound based on the characteristics of human hearing, the result is a pleasing tonal balance at any volume. Simply turn the volume knob and enjoy the same full-bodied sound.
Immerse Yourself in Surround Sound
The new Casiotone offers enhanced stereo sound that’s tailored to suit each tone at the touch of a button, and is surprisingly immersive for its compact size.
A Slimline Case Packed with Compact Innovations
Slim, Lightweight Body for Making Music Anytime, Anywhere
The Casiotone speaker units and structural design are adventurous and creative, achieving a slim and portable lightweight body. Designed to fit into the tightest spots, the keyboards are easy to carry, making transportation a breeze.
Simple Beauty and Intuitive Ease of Use
The Casiotone user interface is elegant and simple, and perfected suited for a musical instrument, making them easy for anyone to use. A reduced number of buttons and knobs creates a sleek appearance, and the intuitive layout lets you find the desired control instantly. The CT-S1 is designed to let you select the sound you want and get right into the music with a single button. The CT-S400 and LK-S450 feature a wider variety of functions and sounds but the LCD screen navigated with a dial makes them very easy to use. Frequently used sounds and settings can be freely assigned to buttons on the panel for instant access.
Smooth Touch and a Diverse Range of Instrument Sounds
The CT-S1, CT-S400 and CT-S450 feature highly durable key mechanisms with muted mechanical noise that are robust enough to resist shaking while being played. Enjoy the dependable, tactile touch of Casiotone to create a wide range of expressive sounds, from acoustic and electric pianos to organs, synthesizers and more.

Wireless Capability Expands Casiotone’s Potential
[Bluetooth® MIDI / Audio]Bluetooth

Audio and MIDI data are transmitted together via USB using a proprietary protocol. The adaptor is the world’s first* to support both audio and MIDI data simultaneously, enabling users to play back their favorite tunes from smart devices through the Casiotone speakers, and transmit MIDI data between their Casiotone and smart devices or other electronic equipment. Although latency and signal dropout can be a problem when using Bluetooth, our system has been carefully optimized for low latency and high stability.
