The catch
Yamaha YDP-105
There is no internal song recorder, so you need a connected device to save a performance.
Side by side
Yamaha YDP-105 vs Casio PX-770: Yamaha sends its sound to a computer, while Casio records two parts locally
Quick verdict
For a shallow room and two-track practice with no other device, pick the PX-770. The YDP-105 is the better choice if recording its own sound over USB counts for more than an internal recorder.
Before you buy
Why, and what it costs you
In a narrow room, depth can count for more than width
At 299 mm deep, the PX-770 saves 123 mm of cabinet depth against the YDP-105's 422 mm. It is also 34 mm wider. A gap between two pieces of furniture may favor the Yamaha, whereas a tight passage in front of the piano may favor the Casio. Measure in both directions.
Where this comes from
Depth before music rest: YDP-105 422 mm, PX-770 299 mm. Listed width: YDP-105 1357 mm, PX-770 1391 mm. This is a conditional workflow inference drawn from these documented inputs. There is no matched performance measurement.

What this page compares
Yamaha YDP-105 vs Casio PX-770, compared on depth before music rest, listed width and listed instrument weight, plus the practice routines that decide the better choice.
Both of these complete entry-level furniture pianos come with three pedals and two headphone sockets. What mainly separates them is a shallower cabinet with internal recording on one side and direct USB audio with Yamaha's GHS action on the other.

You want to record hand by hand with no other device
The PX-770 has a two-track recorder. The YDP-105 has no internal song recorder but does provide USB audio. For a student who wants to record one hand and replay it without borrowing a phone, the Casio makes for a more self-contained routine. If your routine is led by a computer, that choice can flip.

- Better fit
A fixed three-pedal practice station is your aim
Three pedals come with each, and both support half-damper response. That makes the cabinet packages a fairer comparison than a base portable piano plus accessories of unknown content. Check the bench on each exact offer. The selected Yamaha listing explicitly includes one, while the Casio package needs verification.

Spec by spec
Where they really differ
| Spec | Yamaha YDP-105 | Casio PX-770 | In practice |
|---|---|---|---|
| Depth before music rest | 422 mm | 299 mm | The music rest, cable route and comfortable playing clearance are all left out of bare depth. |
| Listed width | 1357 mm | 1391 mm | If the gap on your wall is narrow, check the width as well as the space the bench and player take up. |
| Listed instrument weight | 37.5 kg | 31.5 kg | Work out the load you will be moving from the stated measurement basis, and then add the stand, case and accessories. |
| Internal recorder tracks | No internal recorder | 2 | A large number by itself counts for less than track allocation and independent overdubbing. |
| Live USB audio interface | Yes | No | Whether compatible software can take the internal piano sound directly over USB depends on this. |
Trade-offs
What each pick costs you
With Yamaha YDP-105
- The assembled instrument weighs 37.5 kg, so plan for that during delivery and assembly.
With Casio PX-770
- The USB MIDI connection cannot capture the internal sound as audio directly.
Change of plan
When the answer changes
The real piano sound has to end up in compatible recording software
Go with Yamaha YDP-105. USB audio is documented for YDP-105. With only USB MIDI, PX-770 does not offer the same recording path.
Space for walking in front of the piano is limited
Go with Casio PX-770. At 299 mm deep, the PX-770 saves 123 mm of cabinet depth against the YDP-105's 422 mm. It is also 34 mm wider. A gap between two pieces of furniture may favor the Yamaha, whereas a tight passage in front of the piano may favor the Casio. Measure in both directions.
You need a verified winner on mechanical key noise or on personal playing comfort
Neither model fits. Manufacturer records contain no matched test for those outcomes. Try the instruments under the conditions you intend to play in.
