Yamaha DGX-660 digital piano review


The Yamaha DGX-660 comes with pure CF sampling. This means its sounds were sampled from Yamaha’s CFIII 9’s grand piano to offer clean and clear authentic sound.

In addition to the 10 piano sounds, the piano offers 554 other instrument sounds, giving you lots of room for creativity.

To make the sound more interesting, there is an array of sound effects to choose from. These include 41 types of reverb for simulating the acoustics of various environments. 44 types of choruses to make the sound richer and thicker, and also 26 harmony types to add harmony notes.

Another impressive feature that adds to the sound versatility is a Pitch Bend wheel. It allows you to reproduce some interesting sound effects such as guitar vibrato and choking. You get this by bending notes up and down as you play the keyboard.

Also, to tailor the sound to your liking, there are 5 Master equalizer (EQ) types and a digital signal processing DSP to that effect.


Polyphony is everything, and Yamaha saw to it that this piano upgrade got a higher polyphony of 192 from its previous model. You do not have to worry about dropped notes and will offer superior control and dynamism to any piece.

The Keyboard

With 88-key weighted hammer action, this piano comes with an incredible system that feels very similar to that of an acoustic piano.

This action is called the Graded Hammer Standard (GHS). It will give a heavy touch on the low-end keys and a lighter touch on the high-end ones. This is a great way to develop good finger technique as well as strength for performing on an acoustic piano.


The Yamaha DGX-660 offers the split and dual modes.

  • Split – This is a fun feature that splits the keyboard into two parts. it allows you to simultaneously play two different instruments on each hand.
  • Dual – This allows you in layering two different sounds so that they sound simultaneously over the entire keyboard range.

Recording and Playback

The DGX-660 uses both MIDI (SMF) and audio (WAV) format to record and playback performances.

With the MIDI, you record the MIDI data, which is a sequence of notes, their length as well as their velocity. The piano also has an internal flash memory where you can record and store up to five songs.

On the other hand, with the Audio format, you record and playback the actual sound of the keyboard. Here, you can record up to 80 minutes of recording and save it to a flash drive in WAV format.

Lesson Function

There is an on-board lesson feature with this piano called the Yamaha Education Suite (Y.E.S.). This is a very useful learning tool for beginner pianists as well as practicing students.

Piano Room

The Yamaha DGX-660 provides comfortable play by allowing the player to choose their own environment to play in. The virtual setting also helps you in selecting from a wide range of acoustic and piano choices to customize your setting.

Smart Chord

The Smart Chord is yet another interesting feature that makes you sound like a pro despite your skill level. This feature assists you to play with accompaniments styles with just one finger as long as the music key is known.

Style Recommender

This useful function suggests to you optimum styles depending on the rhythm you are playing for one or two measures.


DGX-660 will integrate with your PC, iOS apps, and your portable music player and other instruments through the AUX IN. It also comes with a powerful speaker system, which can be fine-tuned to play-back any type of music.
