NUX WK-400 Black — 88-Key Scaled Hammer-Action Digital Piano

NUX WK-400 Black is a full 88-key digital piano designed for home musicians who want authentic acoustic-piano feel without the maintenance of a real instrument. Its scaled hammer-action keyboard replicates the graded resistance of a grand, while the matte black upright cabinet with sliding key cover keeps the footprint tidy in living rooms and teaching studios. Inside the slim case sits a DREAM DSP sound engine with 5-level dynamic stereo sampling recorded from a concert grand, giving this model a tonal character that responds to touch rather than just triggering samples.

What Sets the WK-400 Apart in Its Class

Two design choices elevate this piano beyond typical entry-level boards. The self-developed fully weighted hammer-action assembly has been tested for over one million key presses, delivering mechanical durability that outlasts years of daily practice. Combined with four selectable dynamic curves (Soft, Standard, Hard, Off), the keyboard adapts to beginners building finger strength and to advanced players executing nuanced phrasing across the full 88-key range.

Keyboard and Touch Response — Player Feel

The keyboard serves as the heart of any digital piano, and this instrument treats it as such. Every key carries graded hammer weighting, so the lower register feels heavier than the upper, mirroring acoustic-piano physics rather than offering uniform spring-loaded resistance.

• 88 keys provide a full concert range from A0 to C8, leaving no compromises for complex repertoire.
• Scaled Hammer Action Keyboard — graded resistance across registers mirrors acoustic-piano physics
• Four Dynamic Curves (Soft, Standard, Hard, Off) — match sensitivity to playing style, from beginner to advanced
• Three-Pedal Unit (Soft, Damper, Sustain) — traditional piano technique right out of the box

Sound Engine and Polyphony — Tonal Range

A digital piano lives or dies by its sound library and polyphony headroom. The WK-400 pairs a high-end DREAM DSP chip with stereo-sampled grand piano tones layered across five dynamic levels, so quiet playing sounds delicate and forceful playing sounds full and resonant.

• Polyphony: 80 notes — enough headroom for layered voicings and sustained pedal work without dropped notes
• 128 Voices + 1 Percussion Kit — covers acoustic, electric piano, organ, strings, and synths in one instrument
• 52 Demo Songs — built-in repertoire for listening, learning, and inspiration
• Onboard Reverb and Chorus — shape ambience without external gear

Connectivity, Recording, and Practice Tools

Practice, performance, and production converge through the rear-panel jack array. USB-MIDI links the instrument to any DAW on PC or Mac, while stereo line in/out feeds external amplifiers and monitors for stage or studio use.

• USB-MIDI — plug-and-play DAW controller for recording and virtual instruments
• The onboard recorder captures approximately 48,000 notes, letting players document practice sessions directly on the device.
• Metronome: 20–280 bpm, 1–6 beats — tempo and time-signature training
• Headphone Output (6.35 mm) — silent practice at any hour without disturbing others
• Built-in Speakers: 2 × 4.5″ at 10 W each — stereo monitoring without external gear

Who Should Choose This Instrument

Beginner and intermediate players who want an 88-key weighted keyboard with authentic feel at an accessible price will find the WK-400 Black a strong match. Home learners benefit from silent headphone practice, three-pedal technique training, and 52 demo songs that double as listening material. Music students preparing for graded exams will appreciate the graded hammer action and four dynamic curves that mirror acoustic-piano expectations. Hobbyist producers gain a USB-MIDI controller that drops straight into a DAW without drivers, while parents get a matte black cabinet with a sliding key cover that protects the keys from dust and curious fingers.

NUX and the Heritage of the WK-400

NUX has spent years refining digital-piano keyboard assemblies, and this model reflects that accumulated engineering. The brand's self-invented fully weighted hammer-action mechanism was developed to solve the touch-response gap that has historically separated budget digital pianos from acoustic instruments. By pairing that mechanism with a DREAM DSP sound module and a slim upright cabinet, the manufacturer positioned this piano as a practical home solution that doesn't compromise on the two things players notice first: how the keys feel and how the piano tone breathes.
