Key Features of the Yamaha DGX-670 Digital Piano

One of the things that make the Yamaha DGX-670 worth buying is its wide array of attractive features. It has so many useful features that it is somewhat overwhelming to determine which ones are the most beneficial to the buyer.

I will attempt to list what, to me, are its most essential features. They may sway your decision to buy it. Here are my choices of DGX-670’s most attractive features:

1. Authentic Sound and Feel of a Grand Piano

Inside a Yamaha DGX-670 digital piano is Yamaha’s flagship 9 feet CFX concert grand piano. The sound of this grand piano reaches across the furthest spot in a concert hall. Likewise, this digital piano can produce the powerful resonating bass and the sparkling highs of a Yamaha CFX.

Your touches on the keyboard of the DGX-670 will create the respective tonal variations which are sympathetic to the resonance of a grand piano. What is created is an impressive sound quality that is authentic to the sound that only a real acoustic grand piano can produce.

2. Virtual Resonance Modeling

The Yamaha DGX-670 comes with a Virtual Resonance Modeling feature. This VRM feature recreates the actual sound resonances produced when the hammers hit the strings, which reverberate in the soundboard and inside the body of a grand piano. These are rich and complex sounds.

The rich and reverberating sounds envelop the listener. It is not only the strings that were hit that reverberate but the other strings as well. They reverberate sympathetically to the strings that the hammer hits.

Enables Yamaha DGX-670 to Reproduce Complex Sound Quality

A Yamaha DGX-670 is fully capable of reproducing this complex sound quality because of its VRM feature. This feature computes the different states of all the strings connected to the 88 keys on the keyboard. It calculates and completes its function from one moment to the next.

So, this digital piano can recreate the innumerable factors that come into play when a pianist plays the keys of an acoustic grand piano. How the pianist presses the DGX-670 authentically reproduces the keys, the timing, and everything involved in the process.

3. Weighted GHS Keyboard

The Yamaha DGX-670 also comes with the Yamaha Graded Hammer Standard or GHS. Each key in the full 88-keyboard is respectively graded. All these keys can accurately mimic lighter tremble and heavier bass hammers. This is how the DGX-670 can precisely recreate the distinct touch of a real acoustic grand piano.

The GHS features enable the DGX-670 to have a lighter touch on the higher notes or keys and a heavier touch and weighted action on the lower notes or keys. They are just like the action that happens inside the body of a grand piano. 

4. 630 Top Quality Instrument Sounds

Inside the Yamaha DGX-670 are hundreds of high-quality instrument sounds and voices that can accurately mimic the sounds of real musical instruments. Thanks to its Articulation Technology. So, the sounds that you can recreate in this digital piano are the following:
