Yamaha DGX-670 Portable Digital Piano

The world-class concert grand, Yamaha CFX Voice

The Yamaha flagship 9’ CFX concert grand piano, offers sparkling highs and a powerful resonant bass combined in a sound that projects to the furthest reaches of any concert hall.

Enjoy every bit of that expressive control with the DGX-670.

Virtual Resonance Modeling (VRM)

In a grand piano, strings and sounds resonate throughout the entire body of the instrument producing a rich reverberation that envelops the listener in sound. Not only are the strings you are playing vibrating, but other strings ring as a reaction to ones you play. This is one reason the piano sound is so complex and rich.

This phenomena is reproduced perfectly in the DGX-670 through Virtual Resonance Modeling (VRM) which calculates the various states of the strings for each of the 88 notes on the keyboard from one instant to the next. As a result, the DGX-670 reflects the limitless number of factors inherent in playing an acoustic piano such as which keys are pressed, the strength with which the keys are played and pedal timing.

Customize your piano playing experience

Simple and intuitive controls let you choose from different piano and instrument Voices.

Try the acoustics in a rehearsal room, on a stage, in a cathedral, and other venues, and experiment with how far to open the grand piano lid to gain a feel for the subtle differences in sound.

Authentic piano touch, 88-note weighted GHS keyboard

The Yamaha Graded Hammer Standard (GHS) keyboard features a weighted action with heavier touch in the low end and lighter touch in the high end, just like the hammers inside an acoustic piano. Great for the aspiring pianist, practicing on the GHS action builds the proper finger technique and strength for when the time comes to perform on an acoustic piano.

Powerful speaker system

The two-way system features round 12-cm speakers for impressive mid and bass, and a tweeter for dazzling treble. The piano sound is designed to feel immersive from the bench, and the accompaniment is optimized for impact.

The Stereophonic Optimizer—a new kind of headphone experience

When using headphones, the Stereophonic Optimizer lets players enjoy the dispersed sound heard when sitting in front of an acoustic piano. With the Stereophonic Optimizer, Voices sampled from acoustic pianos appear to come from the body of the instrument. This provides a comfortable, natural experience that removes the drawbacks of performing with headphones.

Connect wirelessly for Bluetooth® audio

You can play music through the audio system on the DGX-670 by using a Bluetooth-enabled smart device. Enjoy playing along with your favorite songs directly from your smart device!

Plug-in a microphone for karaoke or singing while you play

Since a microphone can be connected to this instrument and Song lyrics can be shown on the display, you can enjoy singing along with your keyboard performance or along with Song playback. Moreover, you can apply various studio-quality effects such as chorus to your singing voice. You can also cancel the vocal part on audio recordings, letting you sing along with (or instead of!) your favorite artists and groups, and enjoy performing even more.

Audio Play & Recording

Audio files (WAV format) saved to a USB flash drive can be played back on the instrument. You can also record your performance as audio files to a USB flash drive–making it easy to edit your recordings on computer as desired, and share them over the Internet.

Lesson features

The Lesson features are a fun way to learn and master Songs, with notation shown on the display. For example, when you practice the right-hand part, the playback of the left part and other parts will wait for you to play the notes correctly. This allows you to practice melodies and phrases smoothly—even if you are a beginner.
