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

AiX Sound Source: Maximum Range of Musical 
Expression True to Each Instrument’s CharacteristicsAiX 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 That Reflects the Subtlest Nuances of Your Playing

At the heart of the latest Casiotone models are our own specially developed custom LSI processors. These high-performance chips are designed to make the processing required for sound generation as efficient as possible and power our proprietary waveform compression technology that allows for exceptionally detailed and richly expressive sounds. For example, not only are instruments themselves captured in detail at a range of different intensities for every note, but the amplifier sections of vintage instruments are also modeled, requiring high-speed computation on large amounts of data to deliver stunningly realistic and responsive sounds. The Casiotone CT-S500 and CT-S1000V also take advantage of the processing power available to provide class-leading effects.

Distinctive Tones Expand the Possibilities of Expression

ADVANCED TONES: Unique Sounds with Huge Expressive Possibilities

ADVANCED TONES are sonic gems cut using Casio’s advanced technology. A range of acoustic and vintage instruments that feature on countless classic recordings have been modeled to create tones that showcase the power of Casio’s AiX Sound Source.

Intuitive Real-Time Control of High-Quality Effects

In addition to sound generation, Casiotone instruments use the processing power of custom LSI chips to provide powerful effects. The CT-S500 and CT-S1000V in particular feature class-leading DSP effects—a chain of up to four effects from a total of 100 effect types available can be applied to the selected tone. In addition, three system-wide effects are available (reverb, chorus and delay) together with a master EQ. Chain modulation and LFO-based effects for dynamic movement, or try combining spatial effects such as delays and reverbs to add depth and complexity. Or explore the precision amp simulations based on Impulse Responses (IR) from original instruments and amp circuits—there are countless ways to expand the already broad array of built-in tones.

Adding a further layer of expression is Casio’s Active DSP feature. Assign effect parameters to the two physical control knobs on the top panel to give real-time control over the sound while playing. One more way in which the AiX Sound Source delivers unlimited expressive possibilities.

Thanks to the effects module comprising up to four effects, you can apply different effects to multiple tones. For example, use the Layer function to create complex sounds with separate effects on each layer, or use the Split function with separate effects applied to the tones on the upper and lower halves of the keyboard. Team up effects with the auto-accompaniment feature to bring extra depth to your mix. And because there are multiple effects modules, tones can be switched seamlessly with reverb and delay tails naturally playing out—a great feature for real-time performance situations.

Powerful Acoustics from a Compact, Refined Structure

Horizontal Bass-Reflex System: Innovative Bass-Reflex System Packs a Punch in a Compact Space

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.

Volume-Sync EQ: 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.

When playing at low volume

Bass

Treble

When the piano is played at low volume, natural sound is maintained through compensation of the tone in the low and high ranges.

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.

Clean Aesthetics and Intuitive Ease of Use

Retaining the simple beauty of classic musical instruments, Casio designs user interfaces that are simple and intuitive. A minimum of buttons and knobs lend the front panel a clean, uncluttered aesthetic that brings all controls within easy reach. For example, the CT-S1 panel focuses on the simple selection of tones with a single button, while the CT-S400 and LK-S450 with its wide range of functions and tones uses an LCD screen and dial to make adjusting settings and selecting tones a breeze. The CT-S500 and CT-S1000V follow this tradition, so while boasting class-leading effects and other advanced functionality, the user interface is straightforward and simple. Frequently used tones and settings can be freely assigned to buttons whose function is displayed on the LCD screen.

A Fluent Performance Whatever the Tone

The CT-S1, CT-S400, LK-S450, CT-S500, and CT-S1000V alike have robust, durable keys and a mechanism that generates minimal mechanical noise and lateral movement. A consistent feel along the length of the keyboard makes playing predictable and comfortable whether you’re playing acoustic or electric piano sounds, organs, synth tones and more.
