NCK-430
Refined Design, Authentic Performance
The NUX NCK-430 is built for players who want a natural piano experience in a modern instrument. Its 18-layer sampled piano tone captures expression from the softest pianissimo to the strongest fortissimo. A bi-amp, four-speaker system reproduces string resonance and pedal response with clarity, creating the feel of a real concert piano at home or in the studio.
With Bluetooth Audio & MIDI, USB Audio & MIDI recording, OTG mobile recording, and app/software integration, it’s ready for practice, performance, or content creation. The TRRS headphone/microphone jack supports both monitoring and vocal recording—ideal for lessons and livestreams—while the USB port can power mobile devices for uninterrupted play.
The Touch of a Grand Piano, Let Your Fingertips Access the Detail
The NCK-430 features NUX’s proprietary WKJ-03 triple-sensor graded hammer-action keyboard with escapement, delivering the authentic response of an acoustic piano. Its keys are finished with simulated ivory and ebony textures for a natural feel. With seven optimized touch curves, players can choose the response that best matches their style, ensuring a truly personalized playing experience.
Pedal Resonance and String Sympathetic Vibration, Now Kicking in
With 18-layer piano sampling, the NCK-430 captures every nuance of a concert grand, from the softest touch to the most powerful chords. Enhanced with pedal and string resonance, it delivers the natural vibrations and rich harmonics of an acoustic piano, bringing digital realism to new heights.
3 Customizable Pedals with Half-damper Support
On an acoustic piano, the damper pedal doesn’t simply act as an on/off switch—its depth of movement creates a wide range of tonal effects. The NCK-430 faithfully recreates this nuance with half-damper capability, capturing the subtle and expressive qualities of high-end grands and uprights.
Going further, it breaks free from the limitations of traditional pedals, allowing full customization. Players can assign functions such as sustain, soft, sostenuto, vibrato, volume, pitch up, or pitch down, tailoring the pedals to their unique performance needs.
Seamless USB Integration for Recording and Streaming
The NCK-430 connects seamlessly to external devices via USB and provides 10W power output for mobile gear. With just a single USB cable, you can capture lossless, studio-quality audio from the instrument, microphone, Bluetooth, or AUX input, and route it directly into your computer or mobile device. Perfect for recording, livestreaming, or content creation without extra interfaces.
When local sound is disabled, the NCK-430 functions as a MIDI controller to trigger virtual instruments, with playback through its built-in dual-way speaker system—ideal for modern music production setups.
A Wide Palette of Effects and Presets
The NCK-430 comes with preset effect chains that recreate classic styles from different eras—whether it’s the majestic reverb of Vienna’s Golden Hall or the iconic electric piano tones of the 1990s. With 20 artist-designed presets, plus 20 main voices and 130 additional tones, you have endless options to shape your sound to professional standards without complicated setup.
Bluetooth Audio & MIDI
With Bluetooth Audio, the NCK-430 connects to your smartphone or tablet for seamless playback of songs and backing tracks. Meanwhile, Bluetooth MIDI enables integration with the mobile app, making your practice more interactive and convenient.
