Design and Build 


This piano comes in black and white colorways. The design of the PX-350 is very simple, streamlined, and sleek; the keys take up most of the area of the piano, the control area houses buttons combined for different categories, and a compact LCD screen housed in the center.

The dimensions for this piano are 52 x 11.2 x 5.3, and it weighs approximately 25 lbs. without the optional stand, which makes it a great option for its portability. For an 88-key, feature-rich piano, this kind of weight ensures that there would be no issues in taking it to gigs, recitals, practice, or keeping it in a studio or at home.


Even though Casio have received criticism for their grand piano modeling in the past, the grand piano sound in this instrument does a really good job of emulating a real one. With the right kind of sound manipulation, it can be enough to fool the majority of audiences into thinking that it is the sound of a grand piano.

In total, there are 250 sounds in the piano, which are a lot, even for a digital piano. They have been categorized in different soundbanks for the convenience of the users.

Casio has attempted to revamp their modeling technology by integrating the Acoustic and Intelligent Resonator (AiR) engine for shaping up the sound of the onboard samples. It can be safely said that this feature has been successful, with different sound samples including electric keyboards, organs, strings, etc. having a lot of warmth, depth, and character to their sound.

Even though the sounds are great, a lack of customization options to enable a professional musician to be stage ready might be an issue for some players.

The keys on this sleek instrument have an ivory/ebony feel, with a fine and premium character to them. This gives the players a realistic experience mimicking the texture of a real piano.

The PX-350 has fully-weighted keys, and work in tandem with Casio’s Damper Resonance simulator. The bass notes have more weight than the treble notes, which gives the feel and experience of a grand/upright piano.


The Casio PX-350 comes packed with a plethora of features that enhance its functionality and position it as a can-do-all instrument for multifaceted use.

There are 4 in-built reverb effects, as well as 4 chorus effects, and a brilliance effect. With 250 tones and a 128-key polyphony, a lot of sound options are available which have great acoustic quality.

There are 6 demo songs in the instrument, which can be used for reference, practice, or background music. Moreover, there is space for 5 songs (17 tracks) to be recorded, which would surely come in handy for players.

An SP-3 pedal is included, and there is an option for the SP-33 pedal. The in-built speakers have a loud, clear, and articulate quality to them, and can easily be used without amplification in medium-sized rooms and at home.

The piano also offers great connectivity options, with a USB integration that would help players connect the instrument with external devices, as well as being a means to control MIDI devices through a MIDI connection. 

There is also Line In and Line Out functionality, as well as two ¼-inch headphone jacks for those late-night sessions in silence, or instructional purposes.

There are also features for transposing, tuning, and auto-harmonizing, as well as different modes for splitting, layering, and shifting sounds.
