Pairs well with
Description
The Yamaha DGX-670B Portable Grand Digital Piano in Black combines the feel and expressive piano sound of an 88-note weighted digital piano with the creative flexibility of a feature-rich arranger keyboard.
At its heart is Yamaha’s 88-note Graded Hammer Standard – GHS keyboard, with heavier weighting towards the bass and progressively lighter weighting towards the treble. Matt black keytops provide a more tactile surface for regular practice.
For its principal piano sound, the DGX-670 uses Yamaha’s flagship CFX concert grand piano Voice, supported by Virtual Resonance Modeling – VRM, Key-Off Samples and Smooth Release technology.
But the DGX-670 goes far beyond conventional digital-piano territory.
It provides:
-
601 instrument Voices
-
29 Drum/SFX Kits
-
263 accompaniment Styles
-
256-note polyphony
-
16-track MIDI recording
-

Microphone input
-
Score and lyric display
-
Adaptive Style
-
Smart Chord
-
Unison & Accent
-
Piano Room
-
Playlist
-
A 4.3-inch colour display
This combination makes the DGX-670B particularly versatile for pianists who want weighted keys but also enjoy accompaniment, songwriting, arranging, singing, recording and exploring a wide variety of instrument sounds.
QUICK PRODUCT SUMMARY

WHY YOU’LL LOVE IT
The DGX-670 is unusual because it does not force you to choose between a digital piano and an arranger keyboard.
When you simply want to practise piano, you have:
88 weighted keys.
Yamaha CFX concert grand sound.
VRM.
256-note polyphony.
But when you want to explore more, the DGX-670 can become:
-
An arranger keyboard
-
A backing band
-
A recording workstation
-
A songwriting tool
-
A singing setup
-
A practice system
-
A USB audio recorder
-
A home entertainment instrument
That flexibility is the DGX-670’s defining strength.
88-NOTE GRADED HAMMER STANDARD KEYBOARD
The DGX-670 uses Yamaha’s Graded Hammer Standard – GHS keyboard.
Its weighting follows the broad behaviour of an acoustic piano:
-
Heavier towards the bass
-
Progressively lighter towards the treble
For players moving from an unweighted keyboard, the full-size 88-note weighted action provides a much more piano-focused playing experience.
Yamaha specifically describes GHS as useful for developing the finger technique and strength required for acoustic-piano playing.
MATT BLACK KEYTOPS
The GHS keyboard incorporates matt black keytops.
The non-gloss finish gives the black keys a more tactile feel and helps reinforce the piano-focused character of the keyboard.
Yamaha lists the DGX-670 action as GHS with matt black keytops.
FIVE TOUCH RESPONSE SETTINGS
The DGX-670 provides:
-
Hard 2
-
Hard 1
-
Medium
-
Soft 1
-
Soft 2
This allows the keyboard’s dynamic response to be adapted to the player’s touch.
YAMAHA CFX CONCERT GRAND
The principal piano sound is based on Yamaha’s flagship CFX concert grand piano.
The CFX Voice provides the DGX-670 with a powerful, expressive acoustic-piano foundation suitable for:
-
Classical practice
-
Contemporary piano
-
Ballads
-
Pop
-
Jazz
-
Piano lessons
-
Everyday home performance
Yamaha highlights the CFX Voice as one of the DGX-670’s core piano technologies.
VIRTUAL RESONANCE MODELING – VRM
An acoustic grand piano creates complex sympathetic resonance.
Strings interact with one another.
Pedal use changes which strings are free to vibrate.
The instrument’s body contributes to the overall sound.
Yamaha’s Virtual Resonance Modeling – VRM recreates these interactions digitally across the keyboard.
The result is a more connected and responsive piano sound than simple sample playback alone.
KEY-OFF SAMPLES
The DGX-670 includes Key-Off Samples.
These reproduce elements of the subtle sound created when acoustic piano keys are released, contributing additional realism to the piano Voice.
SMOOTH RELEASE
Smooth Release helps reproduce changes in tone associated with different ways of releasing the keys.
This contributes to more natural articulation during expressive playing.
256-NOTE POLYPHONY
The DGX-670 provides 256-note maximum polyphony.
That capacity is particularly useful because the instrument may simultaneously be handling:
-
Piano notes
-
Sustain
-
VRM resonance
-
Layered Voices
-
Accompaniment
-
Song playback
Yamaha confirms 256-note maximum polyphony.
601 INSTRUMENT VOICES + 29 DRUM/SFX KITS
The DGX-670 provides:
601 instrument Voices
plus:
29 Drum/SFX Kits
The Voice library covers a huge range of sounds including:
-
Acoustic pianos
-
Electric pianos
-
Organs
-
Strings
-
Brass
-
Woodwind
-
Guitars
-
Synths
-
Percussion
-
Orchestral instruments
Yamaha’s featured Voice technologies include:
-
9 VRM Voices
-
49 Super Articulation Voices
-
23 MegaVoices
-
11 Natural! Voices
-
26 Sweet! Voices
-
53 Cool! Voices
-
68 Live! Voices
SUPER ARTICULATION VOICES
Yamaha’s Super Articulation Voices reproduce characteristic performance details associated with real acoustic instruments.
Depending on the Voice and playing technique, these sounds can recreate instrument-specific articulations that would be difficult to produce using straightforward keyboard samples alone.
DUAL & SPLIT
The DGX-670 supports:
Dual / Layer
and:
Split
This allows combinations such as:
Piano + Strings
or:
Bass in the left hand + Piano in the right hand
PITCH BEND WHEEL
The DGX-670 includes a Pitch Bend wheel.
This is particularly useful when playing:
-
Guitar Voices
-
Brass
-
Saxophone
-
Synth leads
-
Other expressive instrument sounds
263 AUTOMATIC ACCOMPANIMENT STYLES
The DGX-670 provides 263 accompaniment Styles.
These include:
-
215 Pro Styles
-
19 Session Styles
-
29 Pianist Styles
The Style system generates interactive backing around the chords you play, covering genres such as:
-
Pop
-
Rock
-
R&B
-
Jazz
-
Dance
-
Country
-
Latin
-
Ballads
ADAPTIVE STYLE
Adaptive Style can automatically adjust the accompaniment according to the intensity of your playing.
Play with greater intensity and the accompaniment can become more energetic.
Reduce your playing intensity and the backing can respond more gently.
Yamaha provides Adaptive Style on 50 Styles.
SIMPLE STYLE
Simple Style strips the accompaniment back to a less dense arrangement.
This is useful when you want the instrument Voice and your own performance to remain more prominent.
SMART CHORD
Smart Chord makes sophisticated chord-based accompaniment more accessible.
A simplified left-hand input can generate fuller harmony suitable for the selected Style.
This makes arranger-style playing much easier for beginners.
UNISON & ACCENT
The DGX-670 also includes Unison & Accent.
Unison
Allows Style accompaniment parts to follow phrases you play.
Accent
Allows stronger notes in your playing to trigger rhythmic accompaniment accents.
Yamaha includes these functions on 50 Styles.
ONE TOUCH SETTING
Each accompaniment Style provides four One Touch Settings.
These instantly recall suitable Voices and panel settings for the selected Style.
STYLE CREATOR
Style Creator allows more advanced users to create and customise accompaniment Styles.
PIANO ROOM
When you want to forget about accompaniment, menus and extra Voices, Piano Room provides a more focused environment centred around playing piano.
It is a useful shortcut back to the DGX-670’s core piano experience.
4.3-INCH COLOUR DISPLAY
The DGX-670 features a:
4.3-inch TFT colour WQVGA display
with:
480 × 272-dot resolution
The screen supports:
-
Voice selection
-
Style selection
-
Score display
-
Lyrics display
-
Text display
-
Recording
-
Menu navigation
SCORE DISPLAY
Compatible Song data can be displayed as music notation directly on the screen.
This can be particularly useful for:
-
Lessons
-
Practice
-
Learning new music
-
Following recorded Songs
LYRICS DISPLAY
Compatible Song files can display lyrics on screen.
Combined with the DGX-670’s microphone input, this makes the instrument useful for singing as well as keyboard performance.
LESSON & GUIDE FUNCTIONS
The DGX-670 provides Guide functions including:
-
Follow Lights
-
Any Key
-
Karao-Key
-
Your Tempo
These provide different approaches to learning and practising compatible Song material.
100 PRESET SONGS
The DGX-670 includes 100 preset Songs.
These can be used with the instrument’s playback, score-display and learning functions.
16-TRACK MIDI RECORDING
The DGX-670 provides a 16-track MIDI recorder.
This is significantly more powerful than the basic two-track recording found on many conventional digital pianos.
Separate musical parts can be recorded independently, making it possible to build detailed arrangements.
Yamaha specifies approximately 1MB per Song of recording capacity.
USB AUDIO RECORDING
Performances can also be recorded to compatible USB storage as:
44.1kHz / 16-bit stereo WAV audio
with a maximum recording time of approximately:
80 minutes per Song.
This can be useful for:
-
Listening back
-
Sharing performances
-
Recording finished arrangements
-
Capturing vocals and keyboard together
AUDIO PLAYBACK TOOLS
The DGX-670 provides:
Vocal Cancel
Reduce centrally positioned vocal material in suitable recordings.
Pitch Shift
Change the pitch of compatible audio without changing playback speed.
Time Stretch
Change playback speed without changing pitch.
These functions are particularly useful for learning and playing along with existing music.
MICROPHONE INPUT
The DGX-670 includes a standard mono microphone input.
This allows you to sing while playing or alongside Song playback.
Yamaha also provides effects for the microphone signal, making the DGX-670 useful as a compact home performance setup.
BLUETOOTH AUDIO
The DGX-670 supports Bluetooth Audio, subject to regional availability.
Compatible music can be streamed wirelessly from a smartphone or tablet through the piano’s speakers.
This is useful for:
-
Playing along with songs
-
Backing tracks
-
Reference performances
-
General audio playback
CHORD TRACKER
The DGX-670 is compatible with Yamaha’s Chord Tracker app.
Chord Tracker can analyse suitable audio files stored on a compatible device and help identify the chord progression.
Yamaha notes that it is designed for locally stored audio rather than subscription streaming-service tracks.
USB AUDIO INTERFACE
The DGX-670 provides a:
44.1kHz / 16-bit stereo USB Audio Interface
allowing digital audio communication with compatible computers and devices.
REGISTRATION MEMORY
The DGX-670 provides four Registration Memory buttons.
Registration features also include:
-
Registration Sequence
-
Freeze
These allow favourite combinations of Voices, Styles and settings to be stored for fast recall.
PLAYLIST
The Playlist can contain up to:
500 records
making it easier to organise registrations and settings for different songs.
TWO-WAY SPEAKER SYSTEM
The DGX-670 uses:
6W × 2 amplification
with:
-
12cm speakers × 2
-
5cm speakers × 2
The two-way layout separates larger mid/bass drivers from smaller high-frequency speakers, helping provide clearer reproduction across both piano and accompaniment material.
INTELLIGENT ACOUSTIC CONTROL
Intelligent Acoustic Control – IAC helps maintain tonal balance when the instrument is played at lower volumes.
This is particularly useful for home use.
STEREOPHONIC OPTIMIZER
The Stereophonic Optimizer is designed to create a more spacious listening experience when practising through headphones.
Yamaha aims to make sampled acoustic piano sounds feel as though they are coming from the instrument rather than directly from inside the headphones.
HEADPHONE PRACTICE
The DGX-670 includes a standard stereo headphone connection.
This allows completely private practice without using the internal speakers.
PEDAL OPTIONS
A footswitch is supplied as part of the standard Yamaha package in applicable regions.
For a more traditional piano setup, the DGX-670 also supports the optional:
Yamaha LP-1 three-pedal unit
when used in the appropriate configuration.
Compatible pedal accessories include:
-
LP-1B / LP-1WH
-
FC3A
-
FC4A
-
FC5
OPTIONAL L-300 FURNITURE STAND
The DGX-670 can be used as a portable tabletop instrument, but Yamaha also offers the dedicated:
L-300 furniture-style stand
Available in compatible Black and White versions.
Adding the L-300 and LP-1 creates a more permanent furniture-style piano setup.

DGX-670 VS A CONVENTIONAL DIGITAL PIANO
A conventional digital piano generally prioritises:
-
Piano action
-
Piano sound
-
Pedals
-
Simple controls
The DGX-670 provides these fundamentals but adds a much broader creative system.
It includes:
-
Hundreds of Voices
-
Automatic accompaniment
-
263 Styles
-
Colour display
-
Lyrics
-
Score display
-
Microphone input
-
16-track recording
-
WAV audio recording
-
Bluetooth Audio
-
Playlist
-
Registration Memory
For players who only ever want acoustic-piano performance, a simpler P-Series or Clavinova may be preferable.
For players who want one instrument capable of piano, accompaniment, recording and creative performance, the DGX-670 is much more versatile.
DGX-670 VS CVP CLAVINOVA
The DGX-670 shares several ideas with Yamaha’s CVP Clavinovas:
-
Weighted keyboard
-
Yamaha piano sound
-
Accompaniment Styles
-
Hundreds of Voices
-
Colour display
-
MIDI recording
-
Audio recording
-
Microphone input
The main difference is format.
DGX-670
-
Portable Grand design
-
Approx. 21.4kg
-
Stand and three-pedal unit optional
-
Easier to move
-
Lower-cost route into Yamaha’s arranger-piano concept
CVP
-
Integrated furniture cabinet
-
Built-in three-pedal system
-
More extensive premium feature sets depending on model
-
Designed primarily as a permanent home instrument
The DGX-670 can therefore be thought of as a particularly flexible bridge between Yamaha’s portable digital pianos and CVP-style entertainment pianos.

DIMENSIONS & WEIGHT
The Yamaha DGX-670B measures approximately:
Width: 1,397mm
Height: 151mm
Depth: 445mm
Weight: 21.4kg
This makes it substantially easier to move than a cabinet digital piano while still providing a full-size 88-note weighted keyboard.
BLACK FINISH
The B suffix identifies the Black version of the DGX-670.
The Black cabinet is particularly well suited to the matching optional:
Yamaha L-300B stand
and:
Yamaha LP-1B pedal unit
for customers who want to turn the portable DGX into a coordinated furniture-style home setup.
POWER REQUIREMENTS
Yamaha specifies:
DC Input: 16V
AC Adaptor: PA-300C
Power Consumption: 14.5W
Auto Power Off: Yes.
🎵 FAIR DEAL MUSIC EXPERT VERDICT ★★★★★
Best suited for: Pianists, families, singers and songwriters who want a proper 88-note weighted keyboard but would find a conventional digital piano too limited creatively.
Likely upgrade path: Particularly relevant for players moving from arranger keyboards who now want weighted piano keys, or portable-piano owners who want Styles, hundreds of Voices and much stronger recording functionality.
Useful pairings: The Yamaha L-300B stand and LP-1B three-pedal unit turn the DGX-670B into a much more permanent home-piano setup while retaining its portable keyboard format.
Our tip: Decide first whether you genuinely want the arranger features. If all you need is straightforward piano practice, Yamaha’s simpler P-Series instruments may be easier to live with. But if you’ll use Styles, Voices, microphone input, recording or backing tracks, the DGX-670 gives you vastly more creative room.
FDM view: The DGX-670 occupies a very useful position in Yamaha’s range. You get an 88-note GHS action, CFX sound, VRM and 256-note polyphony, but you also get much of the interactive flexibility associated with an arranger instrument. For players who enjoy doing more than sitting down with a single piano Voice, it offers an exceptional amount of functionality in one relatively portable package.
