The Casio PX-150 is a flexible digital instrument featuring 88 weighted keys and impressive sound recreation. Its sound comes from an Acoustic & Intelligent Resonator sound engine that produces an acoustic sound that is true to the real thing. The PX-150 is a part of Casio’s renovated Privia line, and it features many more options to enhance the user’s playing experience. It responds with tri-sensor scaled hammer action and features three levels of touch sensitivity. It is a very lightweight piano known for being one of the most portable devices on the market.

The PX-150 measures 40 by 10 by 10 inches and weighs only 20 pounds. Its keyboard features 88 tones with a 128-note polyphony. The Acoustic & Intelligent Resonator works as its sound mechanism, and it features tri-sensor scaled hammer action weighted keys with three levels of touch sensitivity.

The versatile metronome ranges from 20 to 255 beats per minute, and it provides 10 preset voices with 60 preset songs and room for 10 user songs. Digital effects include four types of Reverb, four types of Chorus and adjustable Brilliance.

Functions include Duet, Split and Layer modes with 25-step Transpose, Tuning and Auto Power Off. Connectivity options include MIDI In/Out, a damper pedal, 3-pedal connection and a headphone jack.


Key-to-Sound Action: The Casio PX-150 has a keyboard that is redesigned with textured ivory and ebony keys to enhance its realism. In addition, the sound engine along with its key weight takes into account the speed at which different-sized hammers would move in an acoustic piano in response to how the keys are pressed.

Authentic Sound: The PX-150 features an award-winning Privia sound that has been improved for this model. It uses over three times the memory of that used in older generations, and this provides more of a natural piano tone in conjunction with the Acoustic & Intelligent Resonator as a sound source. Also known as AiR, this mechanism produces unmatched realism for more expressive performing.

Song Recording: Included is a built-in track recorder that can store two tracks with playback. This is useful for documenting development with practice sessions, studying performances or keeping track of sudden inspiration.

Connectivity: Digital pianos in the Privia line feature USB connectivity that allows them to be used with Windows or Mac computers without the need to download additional drivers. MIDI connectivity is especially useful for uploading tracks to the computer and easily downloading to the piano.


Acoustic & Intelligent Resonator: The PX-150 features as realistic a sound source as possible with its Acoustic & Intelligent Resonator. Its audio compression technology allows the sound samples to be recorded and reproduced without any sacrifice in quality. When the damper is pressed, the String Resonance System helps reproduce the response of each of a piano’s strings.

Light Weight: While the PX-150 is quite powerful as a digital piano, this would not be expected from its weight. Weighing only 20 pounds, the piano is on record as one of the lightest digital pianos available for purchase. It offers the player much quality in terms of capability, but it is also ideal for carrying around to and from performances and rehearsals.

    This digital piano is great value. We got one with a stand and a bench. It looks great in our living room and it sounds great especially if you plug in external speakers. Perfect instrument for a beginner.

    I’ve had this keyboard for about 6 months now and I love it. The piano sound is just as good as the higher end models because it has the same sound engine. The keys have very realistic ivory feel to them. No need to spend thousands on a high end model, this one has everything you need in a digital piano.

    I checked out several keyboards in this price range at a music store and I’m convinced this is the best digital piano at this price range. I stress this is a digital piano, not a synthesizer, it doesn’t have hundreds of sounds. But as a piano it’s really awesome. Casio did a great job of replicating the sound as well as the key action of a real acoustic piano. To fully appreciate the sound you must use headphones, the internal speakers are inferior. It’s a great instrument for practice, but for performances you will need a set of external speakers.
