Main trade-off
Yamaha YDP-105
It has no internal song recorder, so saving a performance needs a connected device.
Head-to-head
Yamaha YDP-105 vs Casio PX-770: Casio records two parts locally, Yamaha sends its sound to a computer
The short answer
Choose the PX-770 for a shallow room and two-track practice without another device. Choose the YDP-105 when recording its own sound over USB is more important than an internal recorder.
Before you choose
The reasoning and the trade-offs
A narrow room can care more about depth than width
The PX-770 is 299 mm deep compared with 422 mm for YDP-105, saving 123 mm of cabinet depth. It is also 34 mm wider. A space between two furniture pieces may favor the Yamaha while a tight passage in front of the piano may favor the Casio. Measure both directions.
What this is based on
YDP-105: Depth before music rest 422 mm. PX-770: Depth before music rest 299 mm. YDP-105: Listed width 1357 mm. PX-770: Listed width 1391 mm. Conditional workflow inference from these documented inputs. No matched performance measurement.

About this comparison
Yamaha YDP-105 vs Casio PX-770: compare depth before music rest, listed width, listed instrument weight and the practice routines that change the better choice.
These complete entry-level furniture pianos both include three pedals and two headphone sockets. Their main split is a shallower cabinet with internal recording versus direct USB audio and Yamaha's GHS action.
Winner by situation
Start with what you need it to do
The walkway in front of the piano is tight
The PX-770 is 299 mm deep compared with 422 mm for YDP-105, saving 123 mm of cabinet depth. It is also 34 mm wider. A space between two furniture pieces may favor the Yamaha while a tight passage in front of the piano may favor the Casio. Measure both directions.

- Good
- Casio PX-770
- Better fit
You want hand-by-hand recording without another device
PX-770 has a two-track recorder. YDP-105 has no internal song recorder, but does provide USB audio. A student who wants to record one hand and replay it without borrowing a phone gets a more self-contained routine with Casio. A computer-led routine can reverse that choice.
- Yamaha YDP-105
- Caution
- Casio PX-770
- Better fit
You want a fixed three-pedal practice station
Both come with three pedals and support half-damper response. That makes their cabinet packages a fairer comparison than a base portable piano plus unknown accessories. Check the bench on each exact offer, since the selected Yamaha listing explicitly includes one and the Casio package needs verification.

You need the actual piano sound inside compatible recording software
YDP-105 documents USB audio. PX-770's USB MIDI alone does not provide the same recording path.

Meaningful differences
What changes the fit
| What changes | Yamaha YDP-105 | Casio PX-770 | Why it matters |
|---|---|---|---|
| Depth before music rest | 422 mm | 299 mm | Bare depth excludes the music rest, cable route and comfortable playing clearance. |
| Listed width | 1357 mm | 1391 mm | A narrow wall gap needs a width check in addition to the space used by the bench and player. |
| Listed instrument weight | 37.5 kg | 31.5 kg | Plan the moving load using the stated measurement basis, then add the stand, case and accessories. |
| Internal recorder tracks | No internal recorder | 2 | Track allocation and independent overdubbing matter more than a large number alone. |
| Live USB audio interface | Yes | No | This determines whether compatible software can receive the internal piano sound directly over USB. |
What you give up
Every choice has a cost
If you choose Yamaha YDP-105
- Plan delivery and assembly around the 37.5 kg assembled instrument.
If you choose Casio PX-770
- Its USB MIDI connection does not directly record the internal sound as audio.
Recommendation switch
The decision flips if...
You need the actual piano sound inside compatible recording software
Choose Yamaha YDP-105. YDP-105 documents USB audio. PX-770's USB MIDI alone does not provide the same recording path.
The walkway in front of the piano is tight
Choose Casio PX-770. The PX-770 is 299 mm deep compared with 422 mm for YDP-105, saving 123 mm of cabinet depth. It is also 34 mm wider. A space between two furniture pieces may favor the Yamaha while a tight passage in front of the piano may favor the Casio. Measure both directions.
You require a verified winner for mechanical key noise or personal playing comfort
Choose neither. The manufacturer records do not provide a matched test for those outcomes. Try the instruments in your intended conditions.
What matters in practice
Before you choose
What this comparison cannot tell you
- The comparison uses documented specifications and conditional setup reasoning. We have not measured key feel, mechanical noise or speaker performance side by side.
- Dimensions describe the specified body or cabinet. Leave room for the rest, cables, bench and player.
- Check the exact Amazon model, color, supplied accessories, condition and delivery date before ordering.
