Not only does Casio aim for realism in terms of the sound of the PX-350, but also in terms of the feel of the keyboard for the player. The 88 keys of the PX-350 feature Tri-sensor scaled hammer action.

Some possible criticisms

Casio Privia PX-350 Review


Some users of the Casio PX-350 have complained that the button layout feels somewhat crammed and confusing.

However, this is a natural consequence of a digital piano offering such a wide variety of special effects and features. Another criticism of the digital piano is that its internal speakers show a noticeable compression effect at loud volume settings.

Altogether, the Casio PX-350 is just one more model that showcases the striking realism and impressive value that have become standard features of Casio’s Privia line of digital pianos.


Yamaha P115‎

The Yamaha P115 is an excellent alternative to the Casio PX-350. Like the PX-‎‎350, the P115 has 88-fully weighted keys with matte black keytops. Including ‎four touch sensitivity options, compared to the PX-350’s three, the P115 offers ‎slightly more touch customization. There are also 50 built-in songs to play ‎along with, plus 14 more demo songs. Though some aspects of the P115 ‎outperform the PX-350, there are other areas where the Yamaha keyboard ‎lacks. You have access to only two recording tracks, compared to the Casio PX-‎‎350’s 17 tracks. For musicians who value advanced recording options, this ‎difference is significant. You can create nice piano songs with two tracks, but ‎with 17, you can craft a musical masterpiece. Nevertheless, the Yamaha P115 ‎is a solid alternative to the PX-350 in terms of sound. ‎

Yamaha DGX-660‎

Another great alternative to the Casio PX-350 is the Yamaha DGX-660. The ‎soundbank of the DGX-660 is over twice the size of the PX-350’s and features ‎an impressive 554 built-in sounds. If you’re a beginner, you may also take ‎advantage of the Yamaha Education Suite that’s integrated into the piano. ‎With two 6W speakers, the DGX-660 has slightly less volume power than the ‎PX-350. One thing you may enjoy about this digital piano is the Graded ‎Hammer Standard action of the keys. This action is a classic Yamaha feature ‎that doesn’t disappoint. Though this keyboard doesn’t have the PX-350’s 17 ‎track capabilities, you’ll have decent recording options with a 6-track MIDI ‎recorder. ‎

Cosmo Music’s Casio Privia PX-350 Review


The Casio PX-350 is a beautifully designed digital keyboard that offers ‎outstanding sounds and unrivaled recording potential. You can use this piano ‎at home or for professional use. Pianists of all levels commend the world-class ‎AiR sound engine for the rich and authentic tones it produces. Ebony and ‎Ivory keytops provide the optimal feel and grip, which is similar to Grand ‎Pianos. ‎

Since the keyboard is compact and lightweight, you’ll have no problems ‎putting it in a small space or taking it on the road. The Tri-Sensor Scaled ‎Hammer Action II offers smooth touch for every single key. One of the most ‎impressive attributes of the PX-350 is the recording hardware. Composers and ‎recording enthusiasts alike will love the vast potential of 17 tracks. Many ‎keyboards in the same price range can’t compare and often feature less than 6 ‎recording tracks. With loads of fantastic features at a reasonable price, the ‎Casio PX-350 is a powerful machine fitted for amateur and professional ‎pianists.‎
