The Kawai KDP90 makes a fine entry into this latter category. Even using it’s own built-in speakers, the sound is quite amazing.

And not just the piano sounds either—the other instruments here are true to their original counterparts.

If you closed your eyes and just listened, you’d be surprised at how close Kawai got in emulating all these different instruments. Most people probably wouldn’t be able to tell the difference, so it’s great that Kawai really decided to go all the way here.

So let’s dive into the nuts and bolts of what this moderately priced thing of beauty can provide for you.

This wonderful musical instrument comes with many features you might expect to find on a higher-end model. Some of the prominent features include:

88-key Piano Sampling
Advanced Hammer Action IV-F Graded-hammer action
15 exceptional instrument sounds
Dual and Four-Hands modes
192-Note Polyphony
Built-in Alfred Piano Lessons
Grand Feel Pedal System
Sliding Key Cover
Built-in Stereo Speaker System
Audio outputs, MIDI in/out, and 2 headphone jacks
Rosewood Finish
One thing that the KDP90 doesn’t include is a bench, so I guess you’ll have to play standing up. Seriously, though, there are plenty of excellent benches out there at reasonable prices.   So this is, by no means at all, a deal breaker. More at


Kawai calls their method of acoustic piano sampling Harmonic Imaging. Using their own 9-foot EX Concert Piano, Kawai’s sound specialists recorded myriad aspects of this flagship instrument using state-of-the-art technology.

Then, their engineers created what they call stereo “maps” of the EX’s entire dynamic range and, through a process they created dubbed “Harmonic Imaging,” translated those “maps” of “harmonic data” in such a way as to produce an electronic instrument capable of delivering seamless tone quality as the player progresses from pianissimo all the way to fortissimo.

In short, this is a digital piano, yes, but the sound it emits sounds like an incredible nine-foot concert grand piano.


If you’re familiar with an acoustic piano, then you already know that different regions of the keyboard are constructed in different fashions.

For example, some of the bass notes use only one string, then as you go up the keyboard a second string is added and then most of the middle and upper range uses three strings.

The felt hammers, too, have variations in shape and density. In the past, some manufacturers of electronic instruments would sample only a certain number of keys and then sort of “extrapolate” the data for the remaining notes to come up with what they might supposedly sound like.

But what Kawai has done is studied recording techniques of acclaimed studios in Los Angeles and Japan and have painstakingly sampled each and every key of their EX concert grand piano individually. This makes for as close an accurate representation as you can get to the real thing. More at
