Building on the success of the NPK-10, the NPK-20 enhances the acclaimed NUX WKJ-03 keyboard with refined touch response and upgraded sound design. It offers 271 high-quality sounds, automatic accompaniment, professional-grade effects, and a dynamic mic input—delivering a complete solution for practice, performance, and creativity.

Authentic Grand Piano Experience

Equipped with the WKJ-03 Triple-Sensor Graded Hammer-Action Keyboard, the NPK-20 features escapement and synthetic ivory/ebony keytops. Key response has been further refined for improved downforce, rebound detection, and legato performance. Enhanced balance between black and white keys and reduced mechanical noise provide a truly natural piano feel.

Expressive and Versatile Sound Library

A meticulously sampled German 9-foot grand piano forms the foundation of the NPK-20’s sound engine. With a total of 271 optimized sounds across 7 categories, users can easily layer or switch tones—such as combining a piano with lush orchestral ambience—directly from the front panel.

Mic Input with Reverb – Ideal for Performers

Connect a dynamic microphone via the dedicated MIC input with gain control, and enhance your vocals using the built-in reverb—perfect for singer-songwriters and solo performers.

Professional-Grade Effects and EQ

Shape your tone using studio-quality effects:

• Reverb: Hall, Plate, Room, Studio (Pre-delay, Size, Time, Diffusion, Level)
• Compressor: Soft, R\&B, Lyric Piano, Standard Piano (Ratio, Attack, Release, Threshold, Boost)
• Chorus: (HPF, LPF, Depth, Level)
• Delay: (Time, Feedback, High Damp, Level)

All effects are fully adjustable and can be stored and recalled as needed.

One-Man Band with Auto Accompaniment

Control rhythm and harmony in real-time using single or multi-finger chords. A/B variations, intros, and endings allow for dynamic live arrangements. Disabling Auto Chord mode turns the accompaniment into a drum machine—great for expanded performance styles.
