Yamaha DGX-670 Black — Portable Grand Piano With Band-Style Accompaniment

The Yamaha DGX-670 Black is an 88-key portable grand piano built for players who want authentic acoustic feel and band-style accompaniment in one instrument. Built around the flagship Yamaha CFX concert grand voice and Virtual Resonance Modeling, it reproduces the natural resonance and smooth release behavior of a real grand. The Graded Hammer Standard keyboard with matte black keytops delivers heavier-to-lighter weighting for proper technique. A 4.3-inch TFT color display shows notation and lyrics directly on the instrument. This portable grand is the right choice for home players and gigging keyboardists who need flagship piano sound, arranger power, and Bluetooth in one body.

What Sets the DGX-670 Apart in the Portable Piano Category

What makes this model stand out is the pairing of a fully weighted 88-key GHS action with a 263-style arranger engine — a combination rarely found outside Yamaha's portable grand lineup. Virtual Resonance Modeling recreates the sympathetic resonance of an acoustic grand's strings and soundboard, while Key-off Samples and Smooth Release add the subtle mechanical noises that bring piano playing to life. The Piano Room gathers acoustic voices and ambience controls in one dedicated space.

Graded Hammer Standard Action — Authentic Acoustic Touch

The keyboard is the heart of any portable grand, and the DGX-670 delivers an action that mirrors the response of an acoustic instrument. The Graded Hammer Standard mechanism weights the low keys more heavily than the high keys, training fingers to play with proper dynamics.

• Number of Keys: 88 — full concert range for classical repertoire
• Keyboard Action: Graded Hammer Standard with matte black keytops — heavier bass, lighter treble
• Touch Response: Hard2 / Hard1 / Medium / Soft1 / Soft2 — five sensitivity curves

Yamaha CFX Piano Voice and 256-Note Polyphony

The tone generation engine samples Yamaha's flagship CFX Full Concert Grand. With 256-note maximum polyphony, dense layered performances and long sustain pedal passages stay clean without dropped notes.

• Piano Sound: Yamaha CFX with Virtual Resonance Modeling — flagship concert grand tone
• Polyphony: 256 notes — handles complex arrangements without cutoff
• Preset Voices: 601 Voices + 29 Drum/SFX Kits — including 49 Super Articulation

Arranger Styles, 16-Track Recorder, and Bluetooth Audio

The arranger engine is where the DGX-670 earns its portable grand reputation. With 263 preset styles spanning pop, R&B, jazz, Latin, country, and dance, plus a 16-track recorder and USB audio interface, this instrument covers practice, songwriting, and live performance.

• Preset Styles: 263 (215 Pro, 19 Session, 29 Pianist)
• Recording: 16 tracks, SMF + WAV 44.1 kHz / 16-bit
• Bluetooth: Audio streaming with Chord Tracker app support
• Built-in Speakers: 12 cm × 2 + 5 cm × 2, 6W × 2 amplifier
• Inputs: 6.3 mm jack, microphone, AUX IN, pedal unit

Home Pianists, Gigging Keyboardists, and Self-Directed Learners

The DGX-670 is the right choice for home pianists who want flagship grand-piano sound without the footprint of an acoustic instrument, and for gigging keyboardists who need hundreds of voices in a portable body. Self-directed learners benefit from Follow Lights, Any Key, Karao-Key, and Your Tempo lesson modes. Singers can record full arrangements through the 16-track sequencer.

Yamaha's Portable Grand Heritage

Yamaha's heritage as an acoustic piano manufacturer shapes every digital instrument in the lineup, and the CFX concert grand — sampled into the DGX-670 — represents that lineage. The DGX series pairs real acoustic samples with arranger technology developed for stage keyboards, delivering concert-hall piano sound in a 21.4 kg body.
