Casio PX-780 review verdict
This Casio PX-780 review reads the published specifications from a comparison-first point of view: touch, sound, practice fit, value, and limits.
Casio PX-780 is best read as a console digital piano for players who already practise regularly. This review looks at weighted-key feel, sound, practice features, value, and realistic comparison points instead of treating the spec sheet as advertising copy.
Pros
- • Key count: 88 keys, a clear basis for digital piano comparison.
- • Touch: weighted hammer action, so the review stays focused on practice feel.
- • Quiet practice: Headphone practice support.
- • Connectivity: USB MIDI.
- • Use case: Its best fit is home practice.
Cons
- • Main limit: the need for maximum portability.
- • Furniture footprint should still be checked.
- • Used-market condition and support need careful checking.
Casio PX-780 is a console digital piano that makes most sense when its strengths are matched to the right practice situation. The useful points are 88 keys, weighted hammer action, 128-note polyphony, 40W speakers, and a weight of 34 kg. In a digital piano review, those details matter more than broad claims about being the best digital piano overall. For home practice, this model can be a sensible candidate if the layout and feature set match the way the instrument will actually be used. Because it is discontinued, the condition, accessories, and local support matter more than the original launch position. The fairest comparison is with models in the same price and use class, where touch, speakers, headphone practice, and connectivity can be judged side by side.
Casio PX-780 evaluation points
Casio PX-780 key action and touch
Casio PX-780 uses a weighted hammer action. For a digital piano with weighted keys, the important question is not only whether the keys are heavy, but whether they help steady daily practice. The ivory feel key surface is a useful comfort detail. The specification lists 128-note polyphony; that is enough for ordinary pieces, while more layered playing or heavy pedal use benefits from a higher number. This makes the key action a practical comparison point rather than a decorative specification.
Who the Casio PX-780 is for
Casio PX-780 is most relevant for players who already practise regularly. The main use case is home practice. Strengths: a more piano-like touch. Limits: the need for maximum portability. Buyers comparing digital pianos should also check the stand, pedal, headphone jack, app support, and local availability before deciding.
Casio PX-780 sound and speakers
Casio PX-780 offers 18 sounds and 40W speakers. That is the sound side of the review: enough variety for practice, but the real experience depends on speaker power, headphone use, and the room where it will be played. The headphone output supports quiet practice. For lessons, apps, or recording workflows, the useful connectivity is USB MIDI.
What to know before buying the Casio PX-780
Before buying Casio PX-780, compare it with nearby alternatives on touch, sound, portability, and value. The stand is included, which simplifies the purchase. A damper pedal is included, though some players may still want a fuller pedal unit. Because it is discontinued, the condition, accessories, and local support matter more than the original launch position. For searchers looking for a Casio PX-780 review, the practical conclusion is to treat it as one candidate in a digital piano comparison, not as a universal answer for every player.

The number of keys on a digital piano seems like a simple spec, but the decision affects how you learn, what you can play, and how much you spend.
