Only Yamaha can offer the elite quality of the DGX-670 piano Voices. From tonal variation that responds to the player’s touch to the sympathetic resonance of grand pianos, the impressive sound represents an authentic piano-playing experience only an acoustic piano manufacturer can deliver. 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. 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 Modelling (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. 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, practising on the GHS action builds the proper finger technique and strength for when the time comes to perform on an acoustic piano. The DGX-670 offers a wide range of Voices in addition to the piano, from 630 realistic-sounding instruments including electric pianos, organs, and strings, to catchy synthesized sounds. The advanced Automatic Accompaniment Styles make it possible to jam with any number of other “musicians,” from a combo to a big band. There are 263 accompaniment Styles including rock, R&B, and dance. Enjoy an experience that feels just like playing a live session in a band.
