  • The DGX 660 features a grand total of 192 polyphony notes.

We can simply define polyphony as the number of notes a digital piano is able to play while holding the sustain pedal before cutting off the first ones.

If you possess the DGX 650 I do not recommend an upgrade to this digital piano because of it’s increased polyphony ratio, yes polyphony is a big factor, however, is not worth the upgrade in my humble opinion, if you really need a boost in polyphony I suggest using a VST software.


The hammer action system along its 88 keys works well, just as its predecessor it uses the GHS mechanism which is illustrated in the graphical diagram below:

The lower notes respond to a heavier touch while the higher notes are lighter and are much more delicate. The GHS mechanism is considered lower tier when compared to the GH and GH3 as the keys actually feel lighter than those of a real pianoforte.

Voice Selection

The voices on board are divided into categories such as:

  • GuitarsDigital piano voices
  • Organs
  • Pianos
  • E. pianos
  • Flutes
  • Strings
  • Brass
  • Drums
  • Vocals
  • etc.

The DGX 660 offers a grand total of 554 voices, a very impressive amount. The best thing about it’s voicing feature is that the DGX also allows you configure the piano into a split mode and a dual mode.

Styles and Style Recommender

The styles on board are also  divided into categories such as:

  • Jazz 
  • Ballad
  • Pop
  • Dane
  • Swing
  • Rnb
  • Country
  • Ragge
  • ….

The total number of styles is 205, what makes this number so fascinating is the fact that there is an awesome musical technology Yamaha has invented called Style Recommender.

Style recommender  “listens”  to whatever is been played on the piano and then provide users with an ideal accompaniment.

Let’s say you are playing a bosa nova or Beopop piece on the piano, by activating the Style Recommender the internal computer will automatically suggest the appropriate style.


This is the best advancement form the DGX 650 in my opinion, is simply a great addition that brings great musical value to songwriters and singers.

A quick comparison between this two digital piano is important, as potential buyers find them self-researching this often, the Yamaha P-115 weighted keyboard vs the Yamaha DGX 660 digital workstation.

These two digital are quite different in a lot of ways, they present different functionalities and are built to satisfy different types of demands.

  • The Yamaha p-115

The Yamaha P-115 is made for a simplistic piano experience, is a piano that presents a very simple design, simple functions, and a simple interface. This digital piano strength lies in its portability as it only weighs 26 pounds.

  • The Yamaha DGX660

The DGX 660, on the other hand, is more of a hybrid between a keyboard and a piano, as it is equipped with all sort of voices, styles, technologies, and ports.

We can clearly see from the diagram above that the p115 and the DGX660 features some of the same characteristics such as the Key action and Polyphony count, however when it comes to the extras, the DGX 660 really takes this home.

Who is This Product Perfect For?

This Digital Piano is for everyone, thanks to its characteristics and feature both beginners and experts will be able to have a good time playing it. Beginners with no music teachers will find this piano really helpful as the LCD screen provide you with songs notes and songs progressions.

What are the Downsides?

  • Keys

The GHS itself is a good mechanism, however, there is a noticeable difference when compared to a better mechanism such as Yamaha’s GH3 or GH. The keys material are not the best, Yamaha could have used ivory keys instead of plastic.

  • Weight

The DGXs are often considered portable pianos, this is not the case for the DGX 660 as it weighs a total of 90 pounds.

  • Interface

User experience is always a big deal, the interface of this piano in really intimidating. The actual learning curve to master all the functions is going to defer according to the users, I believe the keyboard control panel to be quite overwhelming at first sight.

Customers reviews on the Yamaha DGX 660 Digital piano

Yamaha keyboard piano review

I’m just an old-school piano player, and just wanted a keyboard for practicing piano in private. I’m not super tech-y so a lot of the technology in this thing is totally underutilized. But the keyboard feel is glorious and the piano sound is exquisite. The stand and bench are decent quality and it looks good in the LR (not the finest quality available, but adequate for my purposes. The black color hides the fact that it’s wood laminate, and the lines are simple.)sharon

Yamaha keyboard piano review (2)

This was a gift for my son, which replaced his Clavinova. This was well worth the money! It’s versatile and he loves it!Dan


Just like its predecessor, songwriters and interactive learners will have to pick this up, as it offers a lot of customization and a full musical workstation experience. The DGX 660 is worth its price, as you will get a full keyboard experience, fused with a weighted piano action, however, if you already have a DGX650 it might not be worth upgrading to his piano. Overall this is a great product, that presents a lot of functions to keep users busy experimenting.
