The NUX NPK-20 is our latest powerful portable digital piano. Building off the sound and feel of our bestselling NPK-10, the NPK-20 further optimizes the acclaimed NUX WKJ-03 keyboard and makes it feel even more natural. 

Fully loaded with 271 high-quality sounds in 7 groups, the NPK-20 is also equipped with an automatic accompaniment function for dynamic performances, professional effects based on advanced audio processing technology, and even a dynamic mic input for a perfect performance solution.

The Grand Piano Feel Within Reach

The NPK-20 uses our WKJ-03 Triple-Sensor Graded Hammer-Action Weighted Keyboard (with escapement and synthetic ivory and ebony keytops), and has further optimized its key touch curves and sound design. More professional processing has been made for its key touch in terms of downforce, rebound recognition, legato recognition, etc. The sense of escapement and the balance of the black and white keys are also more even. Moreover, the NPK-20 has added a key noise reduction design. Ultimately, it meets all kinds of playing and performance needs, and restores the real touch of a grand acoustic piano.

A Dynamic and Rich Sound

Providing an accurate and truly grand piano sound can be a tall order. We achieved this for the NPK-20 by sampling a delicate and expressive German nine-foot grand piano. We didn’t stop at just one sound, as the NPK-20 includes a total of 271 high-quality sounds, divided into 7 groups on the top panel. All the sounds have been carefully processed and optimized resulting in a sound selection that is both powerful and rich. The sounds can be chosen or layered intuitively on the panel, such as the sound of piano layered with the ambient sound of orchestra.

A Microphone Input and Reverb – Perfect for Playing and Singing

A perfect solution for the performing singer/songwriter in you. Simply connect a dynamic microphone to the MIC input with adjustable gain control. 

Finally, adjust the on-board reverb effect for the microphone to make your performance come alive!

Professional Effects and EQ

The NPK-20 includes professional effects, including 4 types of reverb (hall, plate, room, studio), 4 types of compressor (soft, R&B, lyric piano, standard piano), chorus, and delay. You can freely combine different effects, set your own parameters and recall them at any time.

  • Reverb: Pre-Delay, Size, Reverb Time, Diffusion, Output Level
  • Compressor: Ratio, Attack, Release, Threshold, Boost
  • Chorus: HPF, LPF, Depth, Level
  • Delay: Time Del, Feedback, H Damp, Level

Also included is a 9-band EQ. You can create and adjust the EQ settings perfect for your performing to your environment and devices (amplifiers, headphones, built-in speakers, etc.), store and recall them at any time.

Auto Accompaniment – A One-Man Band

Our included Auto Accompaniment feature enables you to control a variety of different styles of bands using single/multi-fingered chords. You can choose A/B variations and add intros and endings, resulting in professional sounding live performances. When you deactivate the Auto Chord, the accompaniment styles become a drum machine, giving your performances even more possibilities!

Bluetooth Audio & MIDI

If you want to stream music from your mobile device to the NPK-20, simply connect via Bluetooth Audio. Also, you can connect the NPK-20 to educational APPs via Bluetooth MIDI. And the NPK-20 comes with a free APP, Piano Mate, which provides a variety of sheet music. It’s compatible with other 3rd party APPs as well.

Dual Sounds & Dual Keyboard

You can layer sounds, octave shift for the whole keyboard or split the keyboard to 2 sections and change their sounds and octave separately.

The NPK-20 also provides handy workflow functions. There are 7 user preset slots, convenient for you to quickly save and recall all the sounds and parameters. You can also practice with the built-in metronome which has 3 sounds for you to choose from.

Can't be clean but provides fun.
Size: Small, Number of Items: 1
It's well made and our pup really does like it. The only thing is, it doesn't fully open to clean it out. I wouldn't buy it again for that fact. It's tough plastic and sturdy.

Good contruction but needs a couple revisions
Size: Small, Number of Items: 1
Searching for an interactive toy to feed my beagle his meals from, I first tried the . It split open too easily in rough play and only had the capacity to hold half of a meal. Next I tried for it's larger capacity but it broke at the lid (to Premier's credit they replaced it but I feared it would simply break again). Now on to the Bob-A-Lot. This is a heavy, well made product. I was surprised by the weight. My dog can pick it up but can't carry it for very long. I feel it's not going to break like the others did. That said, the extra weight makes it a noisy toy especially on hard wood floors. The small Bob-A-Lot holds a little over 1 cup of food (large holds 3 cups) but there is a caveat. This is the capacity of the lower chamber. There is actually a separate chamber in the top of the toy that only holds about quarter cup. As a result I have to shake and shake the toy myself to get the food to drop into the lower chamber to load in a complete meal. It's either that or insert food 1 piece of kibble at a time. I wish this toy screwed apart like the IQ Treat Ball or Tug-A-Jug. Despite it's appearance, it does NOT screw apart in the middle. Also slightly annoying is the bottom door doesn't stay fixed into position well. The IQ Treat Ball smartly has several positions for the door to stay locked in. The Bob-A-Lot door is fully adjustable but has often come open more than I want during feeding. As a result the kibble will spill out faster which ruins the challenge. I inquired to Starmark support and they suggested that I use a bit of cardboard or some such to try and jam the door into a specific position. This right here tells me that some additional design could be used. I'd say that the Bob-A-Lot was designed with dogs in mind but not humans. It's a chore to load in the food. And then the door opens too much giving the dog an easy meal. I might even guess that it takes less time for my dog to empty it than it takes for me to fill it. Overall it's the best option I've found but I'm still searching for the perfect combination of all 3 of the toys.

Aggressive chewer approved
Size: Large, Number of Items: 1, Size: Large, Number of Items: 1
Got this to help amuse my 90lb GSD while I was out of town for a month. He gets one meal a day in it, and really enjoys the work. It’s easy, not a puzzle, no frustration, just a “job.” He chewed on the yellow top pretty aggressively while I was gone, and it still works fine. This is a dog that destroys even the most durable chew toys in minutes to hours when he’s anxious, and I imagine he experienced some anxiety while I was gone especially during periods when he was alone. So, I’m quite pleased with the durability. This will definitely stay in the meal service rotation and I will replace it if necessary. One thing to note: the fill hole is pretty small. His kibble is small enough that one might think it would easily pour right in, but no. At some point I’ll get annoyed enough to pull out my drill and make that hole larger.
