At a glance, one may conclude that the Casio PX-780 digital piano has a lot to offer in terms of its design, features, and sound quality. But as the saying goes, we should not judge a book by its cover.

The Casio PX-780 is a model under the ‘Privia’ line which is Casio’s high-end line. The piano comes with lots of features, great design, and realistic acoustic experience. The PX-780 comes with a furniture grade cabinet that is capable of matching any decor. 

The keyboard boasts of 88 weighted keys with ivory and matte finishing. The polyphony reaches a maximum of 128-notes, and other 250 tones available in this digital piano. The keys feature a Tri-sensor scaled hammere action to provide a realistic feel when playing.

The sound source contains Casio’s “AiR” (Acoustic and intelligent Resonator), which helps to generate good piano sound.

The weight is about 31.5kgs which means that the piano is quite bulky. Casio PX-780 was not designed to be on the road, so it’s not your typical portable digital piano.

Though it comes with a lot of similar features as those of portable pianos, this one is more suitable around the house, studio or learning institutions. A definite addition is the price of the piano which is below $1000.


Features of Casio PX-780 Digital Piano

When comparing one digital piano model with another, the features are what you need to look into first. Features are quite crucial since they aid in the production of music. Let’s have an in-depth look at some of the features below.


As mentioned earlier, the Casio PX-780 weighs about 31.5kgs. When a stand is added, the PX-780 becomes 33” high with the width extending to about 53″ and the depth reaches 12”.

The PX-780 was designed to take up less room, which means you don’t require a large space for storage. The piano can even fit well inside your house. Traveling with the PX-780 would be extremely difficult since it has a built-in cabinet.

The Casio PX-780 digital piano has a touch of both traditional and digital features. It comes boarded with a self-inhibiting cabinet with a stylish matte black color and a wooden feel to it.

The piano is a full 88 scale key machine which is considered top level among other digital pianos. It has a sliding cover, which is an advantage as you won’t have to worry about dust getting into the keys.

Exactly at the indentation of the piano lays the interface of the console. The interface has a beautiful design with a combination of knobs and buttons. There is also the inclusion of a small LCD screen.

The screen assists in guiding the player on how to navigate the various tones, rhythms and also displays the current settings on the piano. A novice would benefit from such screen assistance.


The keyboard is one of the most essential parts of any piano. It plays a significant role in a player’s piano world, and Casio made sure to consider its importance with the PX-780 model. The keyboard is graded, weighted with full 88 keys, and its design is one to admire.

Key action and feel are incredible with a nice touch to give the piano an authentic feel. The keys have an ebony and ivory textured finish to prevent slipping of sweaty fingers by absorbing the moisture.

The material of the keys also enables the production of much lesser noise compared to the plastic ones and also feels more natural.

The keys have the “Tri-sensor dynamic” reaction activity that offers a more stable piano expression. What this means is that each of the 88 weighted keys includes a 3-key sensor which helps to determine the tone that should correspond with how soft or hard the keys are pressed.

Considering the price of the Casio PX-780, the design and suitability of the keyboard set it apart from other digital pianos that are expensively priced.

Sound Quality

The Privia PX-780 produces high-quality sound, and this is made possible by two main features that work together to ensure everything runs smoothly.

It has an upgraded memory that allows three times storage from its predecessor and Casio’s very own “AiR” sound source technology, which is the Acoustic intelligent Resonator. The “AiR” helps to capture the tones taken from Casio’s best grand line.

The two features that enable the production of high-quality sound are backed with the graded hammer action produced by the 88 Tri-sensor keyboards. This allows the piano to have a real acoustic feel. The PX-780 also comes with 250 different tones from which a player can choose.

The varieties of tones available are suitable for both practice and stage performances. As earlier stated, the PX-780 polyphony reaches a maximum of 128 notes. Such high note polyphony will ensure little or no notes are dropped when playing the piano several sounds at the same time.
