Casio Celviano AP-S450 Digital Piano

In a slim cabinet, the AP-S450 offers real piano feel with spruce wood keys and 26 sounds including the Celviano crown jewel, a C. Bechstein 9-foot grand.

The Casio AP-S450's 9-foot Hamburg concert grand piano delivers a sought-after pinnacle of musical expression. Captured using dozens of exceptional microphones and meticulously matched to the AP-S450's keys and speaker system, this stunning piano tone is incredibly rich, detailed, and versatile. Damper and string resonance add the natural "bloom" of a full-size grand, along with subtle mechanical sounds that complete the sonic atmosphere of one of the world's most coveted and majestic pianos.

In addition to the Hamburg grand, the AP-S450 also boasts a distinct New York variant of the same marque, voiced with the same painstaking attention to detail. This brilliant recreation completes a tapestry of the most famous acoustic pianos ever played. In your hands, it represents a completely different piano personality that will take your playing in new directions.

The AP-S450's 26 onboard Tones also cover essential instruments like electric pianos, organs, strings and more, inviting a lifetime of musical exploration.

A Touch of Greatness
The Celviano Edition Smart Hybrid Hammer Action keys deliver a gratifying touch-to-sound connection, drawing you ever deeper into the immersive feel of playing a concert grand. These award-winning keys have been refined to harmonize not only with the instrument's sound source, but also with its unique cabinetry and acoustic structure.

Made from a combination of Spruce and resin, they provide the dynamic and natural response you'd expect from a well-regulated read more grand piano, including replicating the individual hammer behavior of each of the 88 individual keys.

Using fine-grained Spruce as opposed to coarser-grained wood adds resilience, density, balance, and a familiar and stately aesthetic. Advanced damping materials make the keys whisper-quiet, and the playable surfaces are subtly textured to provide extra comfort and confidence.

Controls On Demand
Select Tones and adjust various settings with the illuminated touch sensor controls on the left-hand panel. While playing, these controls vanish in order to provide a natural, distraction-free piano experience. Simply touch the panel to activate them again.

Music to Your Ears
The AP-S450's powerful 40-watt stereo amplification system creates a dynamic, rich and nuanced atmosphere for both the player and audience at any volume. Connect headphones to keep it all to yourself, with an automatic Headphone Mode accentuating bass levels at lower listening volumes.

The AP-S450's advanced Hall Simulation places your dream piano in your choice of four dream venues, be it an NYC club, a Berlin concert hall, or a British stadium. Add the Surround effect to place yourself right at center stage, enjoying your chosen piano and ambience from all sides.

See the Light
Above the keys is the Visual Information Bar, a unique and innovative visualizer that reacts to and empowers your playing. As a metronome, it facilitates practice by displaying a pulsing beat in your choice of patterns. By displaying playing strength and pedal depth, it also helps teachers to better help their students to refine their technique. It can even react to incoming Bluetooth audio, providing beautiful and customizable visualization to match any mood. The Visual Information Bar can also be disabled, keeping the front panel distraction-free as you play.

Instant RePlayer
With a piano this inspiring, you'll find musical ideas flowing faster than ever, leading to those inevitable "I wish I'd recorded that" moments. The AP-S450's new Instant RePlayer allows you to go back in time and revisit your recent performances. At the touch of a button, you can immediately hear the last 4.5 minutes of your playing, even if you forgot to begin recording. As you review your playing, the Visual Information Bar serves as a timeline, allowing you to pinpoint the exact musical memory you want to revisit.

Expression at Every Step
The AP-S450 includes three fixed pedals, giving you all the behavior you would expect from a traditional grand. Freedom of expression is preserved with a continuously variable damper pedal, allowing you to select your desired amount of sustain at any given time.

A Perfect Fit
If space is at a premium, the AP-S450 is the instrument you've been waiting for. Casio excels at making wonderful things smaller, and the AP-S450 is a perfect example. It delivers a no-compromise piano experience as the slimmest console piano in its class. Its luxurious yet space-saving design complements any decor in your choice of Black, White, and striking Rosewood finishes, lending traditional piano elegance at a fraction of the size and cost of a full-size grand or upright piano.

Untethered Exploration
The included WU-BT10 Bluetooth Audio and MIDI Adapter opens up a whole world of wireless communication with your favorite apps. Use the Casio Music Space app to adjust your piano's settings, view and annotate sheet music, work with audio files, and much more. With Bluetooth audio, the AP-S450 becomes a powerful, rich, and clear speaker system that easily fills any room, and begs you to play along.
