Main trade-off
Yamaha DGX-670
The body is 445 mm deep before allowing for placement and accessories.
Head-to-head
Choose the DGX-670 for singing, score display and multi-track recording. Choose the XE20 when the arranger piano must be carried often or connected to a separate speaker system.
Before you choose
XE20 is 11.4 kg and DGX-670 is 21.4 kg, a 10 kg difference in the listed instrument weights. Korg is also 109 mm shallower at 336 versus 445 mm. For an accompaniment piano moved between rooms or rehearsals, that combined load and depth change can be more useful than choosing between 263 and 280 styles.
What this is based on
DGX-670: Listed instrument weight 21.4 kg. XE20: Listed instrument weight 11.4 kg. DGX-670: Depth before music rest 445 mm. XE20: Depth before music rest 336 mm. DGX-670: Accompaniment styles 263. XE20: Accompaniment styles 280. Conditional workflow inference from these documented inputs. No matched performance measurement.
Main trade-off
The body is 445 mm deep before allowing for placement and accessories.
Main trade-off
The 12-track allocation includes eight accompaniment parts. The manual supports user-song overdubbing, not twelve independent keyboard parts.


Yamaha DGX-670 vs Korg XE20: compare listed instrument weight, depth before music rest, microphone input and the practice routines that change the better choice.
Both are weighted 88-key arranger pianos for people who play with automatic accompaniment. Yamaha's recording and singing tools compete with Korg's lighter body and dedicated outputs.
Winner by situation
XE20 is 11.4 kg and DGX-670 is 21.4 kg, a 10 kg difference in the listed instrument weights. Korg is also 109 mm shallower at 336 versus 445 mm. For an accompaniment piano moved between rooms or rehearsals, that combined load and depth change can be more useful than choosing between 263 and 280 styles.
DGX-670 provides a microphone input and a 4.3-inch score display. XE20 has no microphone input in its connector list. If singing and following a displayed score are part of the same session, Yamaha combines those tasks. A separate singer's system makes Korg's portability more attractive again.
XE20's sequencer allocates four keyboard parts and eight accompaniment parts, and its manual supports overdubbing a user song. DGX-670 provides 16 recorder tracks. If you want more than four keyboard parts, Yamaha offers more room. For a simpler arrangement, Korg can still layer playing over a saved song. Do not read 12 total parts as 12 independent keyboard tracks.
XE20 has dedicated L/R outputs. DGX-670 uses its shared headphone output for an analog output route.

Yamaha, DGX-670
The DGX-670 puts a score display, microphone input and 16-track recorder in one weighted piano. It makes sense when your routine includes arranging and singing, with a permanent spot for its deeper body.

Korg, XE20
The XE20 combines weighted keys and 280 accompaniment styles in an 11.4 kg body. Dedicated line outputs help when the same piano is used with a separate speaker system.
Meaningful differences
| What changes | Yamaha DGX-670 | Korg XE20 | Why it matters |
|---|---|---|---|
| Listed instrument weight | 21.4 kg | 11.4 kg | Plan the moving load using the stated measurement basis, then add the stand, case and accessories. |
| Depth before music rest | 445 mm | 336 mm | Bare depth excludes the music rest, cable route and comfortable playing clearance. |
| Microphone input | Yes | No | A singing setup needs a documented input and compatible microphone before vocal effects matter. |
| Dedicated line outputs | No | Yes | Dedicated outputs keep an external amplification route separate from the headphone sockets. |
| Internal recorder tracks | 16 | 12 total parts, including 4 keyboard and 8 accompaniment parts | Both support layered recording. Compare the keyboard-part allocation rather than treating all 12 Korg parts as independent keyboard tracks. |
| Accompaniment styles | 263 | 280 | Accompaniment patterns matter for arranging and play-along sessions, not every piano lesson. |
What you give up
Recommendation switch
Choose Yamaha DGX-670. DGX-670 provides a microphone input and a 4.3-inch score display. XE20 has no microphone input in its connector list. If singing and following a displayed score are part of the same session, Yamaha combines those tasks. A separate singer's system makes Korg's portability more attractive again.
Choose Korg XE20. XE20 is 11.4 kg and DGX-670 is 21.4 kg, a 10 kg difference in the listed instrument weights. Korg is also 109 mm shallower at 336 versus 445 mm. For an accompaniment piano moved between rooms or rehearsals, that combined load and depth change can be more useful than choosing between 263 and 280 styles.
Choose neither. The manufacturer records do not provide a matched test for those outcomes. Try the instruments in your intended conditions.
