The AnyTime ATX4 hybrid instruments blend Kawai’s masterful acoustic piano craftsmanship with advanced digital piano technologies. Each piano begins with the solid foundation of Kawai’s award-winning upright and grand pianos, offering class-leading features such as the Millennium III action, considered to be the world’s finest upright and piano actions.
Equipped with Kawai’s most advanced digital and sound technologies, AnyTime ATX4 instruments are also premium digital pianos that can be played silently with headphones. Players can practice new pieces in silence using a variety of high quality sounds, use the built-in metronome then record their performance, or play along with tracks from a Bluetooth-connected smart device.
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.
The latest AnyTime ATX4 grand piano instruments utilise Kawai's brand new GP Touch Muting System. This technology features a significantly improved hammer stop rail system that is able to accurately halt the action's hammer movement immediately before striking the strings, without the need to make special adjustments to let-off position or timing.
This unique design allows pianists to play AnyTime ATX4 grand pianos with exactly the same level of effortless fluency as their standard acoustic counterparts in both normal and muted playing modes, while also enjoying a wide range of convenient and inspiring digital features.
Unlike conventional muting systems that stop the hammer shank at a single position, AnyTime ATX4’s GP Touch Muting System places the stop rail at different points along the keyboard, as close to the hammers as possible, ensuring a firm stop just before striking the strings.
Because of the GP Touch Muting System’s firm and precise hammer stop capabilities, it is no longer necessary to regulate a shallow let-off point for the action. As a result, pianists can enjoy exactly the same grand piano touch feeling in both normal and muted playing modes.
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.
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.
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 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.
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.
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.
Designed to meet the connectivity needs of modern pianists, AnyTime ATX4 pianos feature standard USB and MIDI jacks for connecting to computers or other instruments, as well as Bluetooth® MIDI and Audio technology that allows wireless communication with supported smart devices.
Once paired to a phone, tablet, or laptop, AnyTime ATX4 owners can enjoy a wide variety of exciting music-related apps that enhance their studying and playing experiences, or stream high quality audio directly through the instruments’ headphones without the need for any cables.
The digital features of AnyTime ATX4 pianos are exclusively controlled via the Kawai PianoRemote app, available for both iOS and Android devices.
PianoRemote provides a range of functions, including sound selection and customisation via the Virtual Technician feature, performance record and playback with integrated metronome, and a built-in piano music library consisting of hundreds of classical pieces to enjoy – all accessible from an attractive, intuitive user interface.
The AnyTime ATX4 pianos’ Spatial Headphone Sound (SHS) technology enhances the depth and realism of the instrument’s digital piano sound when listening through headphones or earphones. The player can select one of three different acoustic presets that adjust the spatial positioning of the sound, while also helping to reduce auditory fatigue when using earphones or headphones for extended periods of time.
In addition to featuring a premium quality headphone amplifier, AnyTime ATX4 instruments also allow players to specify the type of headphones connected (Open, Semi-open, Closed, In-Ear, Canal, etc.) to ensure an optimal listening experience.
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.
