Features of the Casio PX-150
Key to Sound Action
The PX-150 features a redesigned keyboard with simulated textured ebony and ivory keys for an authentic piano feel.
The weighted keys along with the model’s sound engine take into account the speed at which hammers of different size move in an acoustic piano relative to the velocity the keys are pressed.
The PX-150 sound mechanism replicates this experience.
The weighted keys respond due to the Tri-sensor action that operates in the same way as a real piano. Bass tones are played heavier and as the keyboard spans toward the treble they play lighter.
The three sensors also detect how the keys are pressed to provide the proper response. These sensors capture the dynamics of performance accurately at any speed.
The award-winning Privia sound has been improved upon for the Casio PX-150. This model uses over three times the memory of that used in previous generations.
This creates a more natural piano tone along with the Acoustic and intelligent Resonator, or AiR, sound source.
This sound mechanism offers an unmatched detail and realism that gives way to expressive performance.
MIDI USB Connectivity
Privia digital pianos feature a USB connectivity that allows them to be used with Windows or Mac computers without the hassle of downloading additional drivers.
MIDI capability allows tracks to be uploaded to the computer or downloaded to the piano.
Functions and Accessories
The Casio PX-150 offers a number of instrument voices including organs, strings and bass. It features Split and Layer modes allowing for bass on one side and layered tones on the other.
Duet mode splits the keyboard into two halves for piano instruction. Optional accessories include the CS-67 stand that raises the instrument’s height and the SP-33 pedal that offers the same pedal function as an acoustic grand.
The built-in track recorder can accommodate up to two tracks with playback. This capability allows the user to record practice sessions to study progress and development.
It is also useful for studying performances or quickly documenting new ideas.
The Pros and Cons of the Casio PX-150
The Casio PX-150 is a top rated digital piano under $500 which provides a realistic feel that mimics the textural sensation of the ivory and ebony keys of an actual piano.
The digital piano is also extremely light compared to many other top digital pianos with weighted keys, making it great for musicians that need to carry the instrument back and forth between venues and practice.
The sound sampling technology makes the tonal expression as true to the acoustic as possible with a String Resonance System that imitates the physical action on the piano’s strings when the damper pedal is engaged.
The speaker system is enhanced when the user plays with headphones, making it a great instrument to use for quiet practice that won’t disturb those nearby.
Some users complain about the weight of the keys, stating that it is too heavy compared to many acoustics.
- Authentic Feel – The feel of the piano’s keys is made to mimic the same sensation of an acoustic piano. Unlike some digital instruments that give a slippery plastic feel, the keys on the PX150 offer a feeling of real weighted ivory and ebony textured keys.
- Weight – The ultra-powerful machine packs a large punch in terms of capability. Coming in at only 20 pounds the PX150 is documented to be the lightest digital piano on the market. This makes it more than ideal for those that need to carry the piano from home to venues and rehearsals.
- Acoustic and intelligent Resonator – The use of Acoustic and intelligent Resonator as a sound source provides as realistic an experience as possible.
- The audio compression technology allows samples to be recorded and reproduced without compromising quality. The String Resonance System replicates the response of each of a piano’s strings when the damper pedal is pressed.
- Sound System – The model features two built-in speakers providing adequate sound quality. With adding headphones, however, the sound quality is greatly enhanced. Many users prefer the sound with headphones as they believe it is richer than that of the speakers alone.
- Key Weight – While weighted key action is necessary to prepare for playing an acoustic some users report that the keys can be a bit too heavy for comfort. Some think the keys are heavier than those found on most acoustics.
The PX-150 is an example of the care put into Casio’s signature Privia line. The most prominent features are its realistic touch response and superb sound quality.
