The Authentic Touch, No Compromises

The Authentic Touch, No Compromises

All AnyTime ATX4 upright and grand piano instruments incorporate Kawai’s specially developed acoustic muting systems which effectively prevent the action’s hammers from striking the strings, thus silencing the sound of each note when played.

Integrated Hammer Sensing System

Integrated Hammer Sensing System

The AnyTime ATX4 pianos’ precise hammer movements are measured with Kawai’s Integrated Hammer Sensing System (IHSS), which utilises high-resolution contact-less optical sensors to provide greater accuracy then conventional key-based sensor systems.

This more advanced approach reproduces the mechanical flow of the upright and grand pianos’ actions more closely, allowing the full range of dynamics to be expressed by the instrument’s powerful digital piano sound engine with natural fluency.

Develped with MPA Supervision

To ensure that all AnyTime ATX4 instruments match the premium quality and excellent playability of their standard acoustic upright and grand piano counterparts, Kawai’s R&D engineering staff worked closely with the company’s internal Master Piano Artisans (MPAs).

These extremely knowledgeable and experienced technicians supervised each stage of the AnyTime ATX4 development process, to ensure that the instruments’ acoustic keyboard action remains exceptionally responsive and balanced, even when used to trigger the digital piano sound engine, and guarantee that the digital piano tonal characteristics and performance are as close as possible to that of an acoustic piano.

Flagship Digital Piano Sound Engine

Flagship Digital Piano Sound Engine

The AnyTime ATX4 instruments incorporate Kawai’s latest digital piano sound technologies from the highly regarded Concert Artist and Novus product lines. When playing through headphones, pianists can enjoy the beautiful sound of the flagship Shigeru Kawai SK-EX full concert grand piano, stunningly reproduced using the advanced SK-EX Rendering sound engine.

The Shigeru Kawai SK-EX concert grand piano was conceived as the next step in evolving the art of the piano. Earning a reputation as the ‘premier piano of Japan,’ it graces the stages of concert halls and musical institutions around the globe, receiving universal acclaim for its exceptional clarity and dynamic range. The SK-EX has frequently been selected by professional pianists at such prestigious events as the Chopin, Tchaikovsky, and Rubinstein international piano competitions. With its magnificent tone and wonderfully responsive touch, the SK-EX can best be described with one word – incomparable.

Multi-channel Sampling

Multi-channel Sampling

The SK-EX Rendering engine’s multi-channel sampling captures the sound from different points of the Shigeru Kawai concert grand.

This modern technique not only allows a broader range of tonal characteristics to be recorded and reproduced, but also improves the connection felt between the keyboard and piano sound, resulting in a more lively and authentic response to changes in dynamics.

Full Resonance Modelling

Full Resonance Modelling

This naturally expressive Shigeru Kawai sound is further enriched by resonance algorithms which model the complex tonal interactions produced by the strings and various other parts of an acoustic piano.

SK-EX Rendering generates resonances for the damper pedal and all 88 keys progressively, allowing the AnyTime ATX4’s digital piano sound to behave just like an acoustic piano.

Rich sound selection

Rich sound selection

Supplementing the beautiful acoustic piano voices, the AnyTime ATX4 pianos digital sound engine also features an excellent selection of additional instruments, ranging from electric pianos and drawbar or church organs, to strings, human choirs, and synth pads, inviting musicians to add greater variety to their performances.

Furthermore, the Dual playing mode also allows two different sounds, such as grand piano and strings, to be layered together for a richer, more luscious tone, while the Split and Four Hands modes divide the keyboard into two independent sections with separate sounds for each. The volume balances and other settings for each playing mode can also be easily adjusted using the dedicated PianoRemote app.
