Revision: Yamaha DGX 630 88 Full size digital piano

With an assortment of useful features available for beginners and professionals alike, the Yamaha DGX 630 88 full size digital piano is a great addition to Yamaha's list of great digital pianos. This review will help you discover all the features of this model, as well as some of the advantages and disadvantages you should also be aware of.

The DGX 630 is equipped with a standard 88-note keyboard with graduated hammer action that has the feel and sound of an acoustic grand piano (heavier on the lower notes and lighter on the higher notes). It also has two USB ports for connecting USB storage devices and other USB compatible devices. The Yamaha DGX 630 also allows you to record up to six tracks. So you can also record accompaniments, rhythm parts and sophisticated melodies - all great features that will really help to inspire the beginner and accomplished musician alike.

A must-have optional upgrade is the Yamaha LP-7A footswitch, which is made especially for this piano and which, in my opinion, offers 3 different sustain modes and is worth buying.

The Good:

What really impressed me about Yamaha's DGX-630 88 full-size digital piano was its authentic feel and surprisingly pleasant sound, similar to that of an acoustic grand piano. Somehow, the two-way speakers in the cabinet emit a clear, warm and well-balanced sound. After trying this piano and some very expensive digital pianos at my local music store, I found myself returning to this piano over and over again.

Another advantage is that the DGX 630 is very attractive with its wooden accent and even comes with a solid matching stand. Although the 630 is not considered an entry-level digital piano, some of its features, such as its six-track recorder and LCD screen that displays scores while playing, can help beginners improve their keyboard skills.

Compared to other similarly priced models and brands, the 630 has proven to offer many advantages, such as a multitude of additional voices, high-quality built-in DSP reverb effects, multitimbral (16 parts), and a digital music book that allows more scores to be downloaded from the Internet.

The Bad:

The downside of many good features is that you end up with a lot of buttons that can be confusing for some people.

Another possible problem with the 630 will be the optional updates available through Yamaha's Digital Music Notebook service that allows you to download piano lessons, new sheet music and other paid updates. Spending extra money on an optional upgrade may be a chore for some, but a bonus for others who really want to unleash the potential of this versatile digital piano.

This digital piano is perfect for:

  • start studying piano as you can:
    • playing digital scores on the screen
    • record your workouts
    • use the built-in metronome
  • accomplished musicians who want the sound and feel of an acoustic piano without paying a high price.
  • someone who has little room in their house or apartment since this portable digital piano can fit almost anywhere.

A notice from the owner of a Yamaha DGX 630

By Marta Consiquelo

I love this keyboard. Don't underestimate yourself and don't think it would be better to spend $200 or less on another keyboard. Believe me, the money is worth it. If you're looking for a keyboard that sounds good on an acoustic piano, this one is for you.

It comes with lots of sounds and whistles, which is perfect for all the needs you might have... but if you're like me, then maybe you just want a big, heavy keyboard that's authentic. The keys are as sensitive as a piano, if not more so, so you can focus on the playing. I've tried and played keyboards from $400 to $3000 and I chose this one specifically for its sound. It's the crème de la crème.


  1. Your review of the Yamaha CP33 was helpful. My Yamaha Pf-15 died, and I’m toying with the idea of buying a replacement. I have a killer upright piano: a 52″ Bohemia, from Fandrich. But I worry about offending my neighbors late at night.

    I was thinking of a used P-90, thinking it might have a really good, heavy action, and be cheaper. Is the CP33 a real upgrade, or just newer do you think? Also, have you looked at the P-155? It’s only about $200 more than the CP33.

    Thanks for the kind comments David!

    As far as the Yamaha P-155, I think it’s a fine piano from the feedback I’ve heard. Some folks have complained that the action is a bit heavy but within a few days this feeling goes away. I’ve also heard that although the piano sound is nice it could be a bit better.

    However, at least it has powered speakers which the CP-33 does not. Also it’s available in many different tones/colors.

    I would advise you to try this out in a retail store *before* you decide to buy. Then once you’ve settled on the piano you like start price shopping. :)
