Yamaha DGX-670 review

The DGX-670 is a new addition to Yamaha’s very successful DGX range. Being a DGX means delivering high-quality sound with a wide range of features. The DGX-670 continues the trend and does so with perhaps the best sound and feel to date.

The Yamaha DGX-670 is a portable 88-key keyboard piano with 256-note max polyphony. It combines the realism of a piano with the multi-functionality we have come to expect from a DGX keyboard. Weighted keys, over 600 voices, and Yamaha’s flagship CFX Concert Grand for well under $1000; sounds good.

Our verdict on the DGX-670 4.5

The DGX-670 is a clear improvement on a series that was already very successful. Yamaha has created a keyboard with some advanced functions and easy-to-use controls. It sounds better, feels better, and is tougher than previous models. Easily one of the best portable keyboard pianos in its class.

Who does it suit?

The DGX-670 is user-friendly enough for complete beginners and sounds good enough for professionals. It’s definitely an excellent keyboard to learn or perform on. The only consideration might be the price; if you are an absolute beginner, there are cheaper (stepping stone) options available.

  • Stunning CFX Concert Grand sound.
  • Realistic GHS keys.
  • Simple layout.
  • Smart functions – Adaptive Style, Chord mode, etc.
  • 16-track MIDI recorder.
  • Bluetooth.
  • Microphone input.
  • Relatively heavy.
  • Layering limited to two sounds.

Features 4.5

The DGX-670 is packed with features, and most of them are tailor-made for performers. One of the features we love is Yamaha’s Adaptive Style, which automatically adjusts to your playing.

Most keyboards with built-in styles/rhythms give you a couple of variations, but they aren’t always convincing. The DGX 670 has realistic variations, but more importantly, it changes in response to your playing style: velocity, chord type, etc. Effectively, it becomes more like playing with a band with flexibility rather than a rigid track.

You’ll see a Piano Room button shaped like a grand piano. When activated, Piano Room mimics the room sound from various locations, including concert halls.

Smart Chord is another interesting feature that allows you to trigger complex chords from one or more notes. If you are a performer who wants to sound more interesting, it’s an easy way to turn basic triads into 7ths/9ths, etc.

As far as editing your sound goes, you have Dual Mode and Unison and Accent. Dual Mode is basically layering two sounds together to create a new voice.

Unison and Accent is a little more interesting because it’s more about how you perform. It doubles the voice for melody lines (right hand) and adds accents to target notes triggered by velocity. It gives you a different way to approach your performance and adds a new dimension to your playing.

The DGX-670 has a microphone input, and your voice comes straight out of the built-in speakers. This feature is a really nice addition for singer-songwriters. A 4.3″ LCD helps you get around all of the keyboard functions and also acts as a score display showing/scrolling MIDI song notation.

As well as performing your music, the DGX-670 is great for recording, too, with an onboard 16-track MIDI recorder. The built-in recorder provides up to 80 minutes of 16-bit/44.1 kHz recording with 20 MB of internal storage (USB flash drives can be used).

USB connectivity makes it easy to connect to your computer/DAW for more advanced recording. Bluetooth is also available if you just want to jam along with your favorite tracks.

Sound quality and feel 4.5

Before we get into the quality, let’s just cover the numbers. The DGX-670 has 601 voices, 29 drum/SFX kits, and over 250 styles. It also has 100 preset songs and onboard effects, including reverb, chorus, and compression.

The sound of Yamaha’s stunning CFX Concert Grand has been impeccably sampled, and it sounds terrific. It’s no real surprise, as we are used to that from DGX keyboards.

The thing that makes it better than ever is the GHS (Graded Hammer Standard) keyboard. The weight of the keys is beautifully graded from top to bottom, and the matte finish absorbs moisture, making it more comfortable to play.

Feeling more realistic and comfortable means you can play with more expression and get the most out of the sounds. Yamaha’s Virtual Resonance Modeling enhances the expression of your playing by mimicking the behavior of a real piano.

The grand piano sound is the star, but there are many others, including Super Articulation Voices. These voices are non-keyboard instruments, like a saxophone, for example. Adjusting your velocity brings out different expressive nuances, like making the saxophone growl, and so on.

Besides the piano sounds, we particularly love the strings and guitars.

Layout 4.5

The layout of a keyboard’s top panel is very important because it determines how easily you can navigate sounds and functions. Yamaha rarely goes far wrong in this area, but what we like about the DGX-670 is that everything is very stripped back and sleek. The top panel has a lot going on, but it’s organized in the most minimal way possible.

The left of the panel deals with songs and styles, the right deals with sounds, and in the middle is the mich-improved LCD screen. A lot of the work will be done using the screen and the multi-function buttons underneath it.

The multi-function buttons do different things depending on the current screen display. For example, in the mixer screen, they can raise/lower levels, and in the style screen, they can add/remove instruments.

The best thing about all of the DGX-670 controls is that they are smart, and there are no unnecessary buttons. For example, the style controls allow you to strip a track down to just the rhythm section with a single button. If you want to edit further or even change the type of chords that the virtual band plays, you can do so from the LCD screen. You can set chord types by key, genre and decide how and when they are triggered; it’s very clever.

Selecting and browsing sounds is a similar process. There are category buttons, and you can choose further via the display. Layering and splitting voices is simple because you can turn any layer on/off with a single button or adjust levels using the mixer page. You can store layered sounds and their settings in any of the four available memory banks for instant recall.

Navigating any menu on the screen is done using the scroller knob and the directional selector buttons underneath.

At home 4.5

The DGX-670 is the ideal home digital piano for a few reasons. Firstly, it looks, sounds, and feels great. Secondly, it’s portable if you want to move it around the house, and lastly, you can add a three-pedal stand if you want a stationary digital piano look.

The onboard recording is great for recording ideas, and if you want to develop them further, you can plug it into your DAW.

On stage 4.5

There isn’t too much to say here other than the DGX-670 is built for performing. Whether you just need a fantastic piano, backing tracks, lots of sounds, a microphone input, it does it all.

Build quality 4.0

DGX keyboards are relatively cheap compared to very high-end stage pianos, which sometimes meant the build quality suffered. One of the biggest upgrades for the DGX-670 is the improved build quality. It looks and feels a bit more expensive than previous DGX keyboards.

It weighs not much under 50 lbs, so it might seem a little heavy, but it’s worth it. It now feels like those lovely hammer action keys are housed in a solid unit. The same can be said for the buttons and controls; nothing feels or looks cheap.

Compared to other stage pianos

The DGX-670 improves upon previous DGX models, but what about the competition? Here are a few alternatives that you might want to check out. Also, check our recommendations for best digital pianos and keyboard/stage pianos.

DGX-670 vs. Yamaha YPG-535

If you want to stick with Yamaha but go for something a little cheaper, the YPG-535 is a solid choice. It does much of what the DGX-670 does, just at a lower level, but it still sounds great.

DGX-670 vs. Casio Privia PX-5S

The PX-5S might not looks like the typical stage piano, but this compact instrument still packs in beautifully scaled hammer action keys. Casio also has gorgeous grand piano sounds; we think the DGX sounds a bit better, but it also weighs twice as much.

DGX-670 vs. Kawai ES110

If you want something with more of a piano-only feel, Kawai is usually a good place to start. The ES110 isn’t a flagship model by any means, but it’s light, compact, feels good, and sounds like a Kawai (which is awesome).
