Review: Kawai Novus NV-6 – Hybrid Digital Piano

Virtually indistinguishable from acoustic instruments, hybrid digital pianos impress with their excellent touch and sound. The new Kawai Novus NV-6 lives up to this expectation and sets itself apart with a sophisticated transducer-based playback system.

The Novus series belongs to the upper class of digital pianos, yet it stands out thanks to its transducer-based soundboard. The Kawai Novus NV-6 takes full advantage of this, offering a noticeable improvement and refinement over its predecessor, the NV-5S.

The current Novus models have undergone several upgrades, particularly in terms of sound. The collaboration between Kawai and physical modeling experts Pianoteq, announced at the 2025 NAMM Show, is especially noteworthy. One outcome of this partnership is the recently released expansion module for Pianoteq, which includes superbly sampled Shigeru Kawai SK-EX concert grand piano sounds.

Another exciting new feature: Kawai has now built a USB audio/MIDI interface into the new Novus series. The Kawai NV-6 and the larger Kawai NV-12 therefore offer seamless integration with external audio applications. This opens up new possibilities for recording, audio streaming, and online lessons with extremely low latency via a simple USB connection.

Like a Real Piano?

Like its predecessor, the new Novus upright is visually almost indistinguishable from a real piano. On closer inspection, however, the cabinet appears slightly more compact, perhaps comparable in size to the top model of the CA series. The Kawai CA-901 already received top marks in our tests for both sound and playability, bringing several hybrid-style features to the mid-range digital piano market.

In terms of sound, though, the Kawai Novus NV-6 clearly goes beyond expectations for an upright-style instrument. In some respects it even surpasses the Kawai CA-901. But first things first.

One particularly striking moment during our test deserves mention: When playing the upright piano sound of the Kawai Novus NV-6, you could easily believe you were sitting at a real acoustic instrument. It feels like the perfect illusion—until the grand piano presets suddenly transport you into the sonic world of a full concert grand. Even then, the instrument retains a remarkably acoustic character.

Kawai also highlights the new sounds derived from its flagship concert grand pianos. Not only is the renowned Shigeru Kawai SK-EX available as a concert grand preset, but the newer Competition Grand, already very popular in the current CA models, has also been added to the Kawai Novus NV-6’s extensive sound library.

High-Quality Hammer-Action Keyboard

Sit down at the piano, close your eyes, feel the keys, and simply start playing. The first impression comes from the tactile connection with the keyboard. With the Kawai Novus NV-6, you can expect performance of the very highest standard. In terms of playing feel, the NV-6 ranks among the finest digital pianos available, surpassed only by Kawai Novus NV-12, the flagship model of the series.

The NV-6 achieves this authentic piano touch through a dedicated hammer action modeled on that of an upright piano. Its foundation is the proven Millennium III action, which is also used in Kawai acoustic pianos. The hammers are slightly different in appearance because they trigger the instrument’s digital sound engine instead of striking strings.

Optical sensors precisely detect the movement of the keys and hammers, ensuring that nothing interferes with the purely mechanical motion between the action and the electronic sound generation.

Premium materials and an exceptional playing experience are the guiding principles here. Real wooden keys come as standard, along with features such as Ivory Touch keytops and let-off simulation. There is no need for speculation about partial hybrid constructions or decorative wooden elements, as sometimes found in other brands. In the Novus series, the keys, the action, and the piano touch are the real deal.

What Does the Damper Mechanism Do?

The keyboards in the Novus series take another factor into account when the sustain pedal is used: As soon as the pedal is pressed, the weighting of the keys changes slightly. This is a subtle effect, but it makes playing with the pedal feel even more authentic. Because the damper mechanism is disengaged, the keys require slightly less effort to depress. This feature is characteristic of the Kawai Novus series and represents a rare level of realism in digital pianos.

Transducer-Driven Soundboard

One particularly distinctive feature and unique selling point of Kawai digital pianos is their audio system. Rather than relying solely on conventional speakers, it also makes use of the resonant properties of a real soundboard. This approach provides tactile feedback, as the soundboard’s vibrations are transmitted through the cabinet and keyboard. Moreover, it creates a room-filling sound dispersion. In addition to the transducer-driven soundboard mounted at the rear, four main speakers and two tweeters deliver finely balanced, high-resolution sound reproduction.

The system has been completely redesigned for the latest generation and now uses newly developed transducers. Compared with the previous Novus models, the sound of the Kawai Novus NV-6 has noticeably improved.

SK-EX Rendering & Harmonic Imaging XL

The Kawai Novus NV-6’s acoustic piano sounds are exceptionally vivid, thanks in no small part to its sophisticated playback system. At the heart of the instrument lies its sound engine, bridging the gap between the keyboard action and the audio output. The resulting tone can best be described as dynamically nuanced, and resonant, making the instrument a real pleasure to play.

The NV-6’s SK-EX Rendering engine delivers highly detailed piano sounds. At the same time, it is one of the most flexible sound engines available in a digital piano today. This becomes clear when exploring the numerous voicing parameters available. You don’t need to be a piano technician to use these options: Simply let the presets guide you and choose the one that best matches your musical preferences.

Each concert grand retains its distinctive character, while the presets adjust their presentation: brighter or more mellow, with more or less resonance, more percussive or more rounded in character. These variations are not only inspiring, they also allow you to find a sound that fits almost any musical style.

You can easily access all these settings via the integrated touchscreen, or more conveniently through the free PianoRemote app for Android and iOS devices. For more advanced customization, the Virtual Technician functions allow you to make detailed adjustments to individual aspects of the sound, enabling you to shape your own personalized concert-grand character. This is not only enjoyable for piano enthusiasts, but also offers professional-level flexibility for recording purposes.

Digital Piano Functions on the Kawai Novus NV-6

In terms of features, the Kawai Novus NV-6 has it all. From standard functions such as transpose, tuning, touch curves, and local MIDI control to more advanced parameters for shaping the instrument’s acoustic response. The new USB audio/MIDI interface is particularly noteworthy because it allows seamless integration with external audio systems. The NV-6 can also connect via Bluetooth, which is convenient if you prefer a wireless link to a tablet or smartphone. However, USB MIDI and, above all, USB audio are generally more reliable and allow for audio transmission with minimal latency.

Conclusion: Hyperrealism in Piano Design

A classic just got even better. Anyone familiar with the Kawai Novus NV-5S will immediately notice the improvements. Thanks to the even more precise coordination between the speaker system and the transducer-driven soundboard, the sound has been significantly refined. And the new Kawai Novus NV-6 not only sounds sensational, it also plays superbly. This hybrid digital piano is certain to attract a great deal of attention.

With this instrument, Kawai clearly demonstrates the level of playing realism that can be achieved when components from acoustic piano construction are combined with high-resolution digital sound generation. In terms of both touch and sound, you repeatedly find yourself under the illusion of playing a real acoustic instrument. Only the fact that you can switch between different digital piano voices and concert grand pianos rather than being limited to a single upright piano adds a slightly “hyperreal” dimension to the experience.
