In this The One Smart Piano review we will take a look what makes this keyboard smart, how does it work and our final thought on if you should be sitting this one out.

Overview of The ONE Smart Piano

Traditional piano teachers are often rightly concerned that if young people use apps to learn to play a digital piano, they will lack well-rounded development and fail to learn skills that will allow them to play an acoustic piano without assistance.

The ONE Smart Piano Weighted 88-Key Digital Piano is designed to alleviate that concern; the keys are fully weighted, for finger strength and technique, and the light-up functions are discrete and effective, but can be turned off, and the three built-in foot pedals help learners build more skills and play more complex pieces.

In short, if a student uses the app to its full capability, participating in games, challenge modes, and following the lessons, they will learn piano playing and music reading skills that can last a lifetime, even if they are playing a traditional piano.

While many digital piano companies are coming out with companion apps that augment the keyboard, the ONE Smart Piano Weighted 88-Key Digital Piano is different. Controls on the keyboard itself are limited to the metronome, tempo, and master volume control. In other words, without the app, not only can you not access the lessons, games, and song library, but you also can’t control any of the other piano keyboard functions or settings. The app doesn’t just go along with the keyboard, but is integral.

As a console piano alone, The ONE Smart Piano, Weighted 88-Key Digital Piano is fairly slim on features.

Headphone jack

It has a headphone jack on the front and an audio out port on the back, that can be used for headphones or external speakers or amplifiers. The other data cables accessible on the back are proprietary, non-standard data connections

An Alternative Product to Consider

The ONE Smart Piano, Weighted 88-Key Digital Piano represents a practically unique relationship between the console piano and the apps that interact with it. While other piano manufacturers are incorporating more app connectivity all the time, with the ONE Smart Pianos, the app is integral to the capabilities of this instrument.

Unfortunately, in this case, that dependency can become a weakness. While the ONE Smart Pianos claim to be iOS and Android compatible, and their FAQ state that they “should” work with Amazon tablets and devices, they frequently do not.

The company appears to no longer be updating the Android version of the app at all. When the app doesn’t work, this large, 117 pound instrument is extremely limited in capabilities. Furthermore, because the ONE is a crowdsourced product created by a startup, there is no assurance of ongoing updates from the company, and support is poor or nonexistent.

 While the ONE Smart Piano, Weighted 88-Key Digital Piano represents some exciting advances and capabilities in console keyboards, there is a better alternative.

Consider pairing the Yamaha YDP103R Arius with The ONE Hi-Lite Learning System.

Both the Yamaha YDP103R Arius and The ONE Smart Piano, Weighted 88-Key Digital Piano give you:Yamaha YDP103 Arius Series Digital Console Piano with Bench (YDP103R)

  • 88 full-size fully weighted keys
  • A handsome console with a sliding keyboard cover
  • Three foot pedals
  • 64 levels of polyphony
  • USB connectivity

A Yamaha YDP103R Arius would also give you several things the ONE Smart Piano doesn’t, including:

  • Matte black key tops
  • Touch responsive keys
  • Half-pedal functions
  • AWM stereo sampling sound engine
  • 4 types of reverb
  • Dual, layered, and duo keyboard functions
  • Adjustable tempo, transpose, and tuning
  • It comes with a piano bench that matches the console

The ONE Hi-Lite Learning System is a slim bar that sits across the top of an 88-key keyboard with no installation, so you can use the same lesson-light system as The ONE Smart Piano, and access all the songs, games, lessons, and exercises in the ONE Smart app.

With this setup, you would miss out on some of the instrument voices and rhythms that come with the ONE Smart Piano, Weighted 88-Key Digital Piano, but if the app didn’t work or you no longer needed the key lighting system, you could easily remove it and still have a fully functioning, attractive console piano with great sound.

The ONE Smart Piano, Weighted 88-Key Digital Piano and a package of the Yamaha YDP103R Arius with the ONE Hi-Lite Learning System cost about the same amount of money and take up the same amount of room in your home, without some of the technological risks associated with investing in the ONE Smart Piano, Weighted 88-Key Digital Piano. It’s a good compromise between the exciting technology developed by the ONE team, and the desire to invest in a consistently performing musical instrument.

Louise Bishop’s Review of The ONE Smart Piano


The ONE Smart Piano represents some exciting advances in how we learn, play, and understand music. The app is powerful, engaging, and enables a huge range of musical experiences and lessons to suit every taste.

However, without the app, the keyboard itself lacks many basic functions for a console piano in this price range, and the app performance is unstable. It is also annoying to have a company produce a proprietary USB cable in this day and age.

A better alternative at this time would be to get a console piano from a different company, and add the ONE Hi-Lite Learning System, to get the best of both worlds, and hope for more mature technology in the future.
