Thanks to the weighted keys, this instrument can replicate the resistance that you always feel when playing a traditional grand piano.

How about its design?

With a slim, compact and lightweight design, you are able to transport it to anywhere you want.

Advanced Features

Since the appearance of CDP 235 is to replace the CDP 230, it boasts about some new features.

LCD Screen

Instead of giving a gold/orange color from the previous model, the Casio CDP 235 comes with the display screen with backlight in a blue color. The button description text is in a white color that makes everything easier to read.


When the first model only comes with 48 notes of polyphony, this instrument has 64 notes of polyphony. That means the piano sound, itself, is better.

Besides, layering two sounds together is less uncertain.


With a spring-less hammer system, the Casio CDP 235 similarly works as grand pianos and gives a naturally firm keyboard touch at the same time.

When playing the lower notes, you recognize they are relatively heavier than the higher notes, like the keys on the grand pianos.

Touch Response

Touch Response allows you to add a subtle difference to notes by changing how much pressure you touch the key.


If examining vs Yamaha P115, the speakers from the CDP 235 clearly and powerfully reproduce a rich, dynamic range. With two speaker systems of 8W + 8W amplifiers, they deliver rich, high-quality, and fat sounds from the bass to the treble.

Chord Book

If you don’t know how to play a specific chord, you can avail the Chord Book as a reference. Select the chords you want to play, hear their sound and simply practice.

Step Up Lesson

The best way to start a song is to separate it into short phrases, practice each phrase and then put all together. The new function of Step Up Lesson does exactly what you want, allowing you to improve your playstyle.

Thanks to 152 built-in songs with 50 exercise phrases, you can cover a massive range of genres for lesson play.

Or you can load more songs from external sources. But, note that the fingering guide won’t be shown for such songs.

Other Features To Consider 


Casio CDP 235

First of all, let’s talk about a massive tone list!

With 700 high-quality tones, you can play tunes from different genres. You also welcome 200 rhythms and an advanced auto accompaniment with lots of styles such as Latin, Samba, Cumbia, Calypso, etc.

Thanks to the dual-element AHL sound system, the quality of the tones is exquisite. It’s because this system utilizes waveforms of distinct samples of the same notes at the light and strong key pressures.

Music Preset

If you want to change the keyboard setup such as tempo, tone, rhythm, etc., it’s best to choose a Music Preset. With 305 music presets, you can cover a massive range of musical genres.

It’s ideal for playing a particular song as well.


Thanks to the USB port, it’s easy to connect to the computer from Windows Vista to Windows 10 and Mac OS. Especially, the SD memory card slot is convenient for transferring data, up to 32GB.

Or in case you need to connect with another GM-compatible device or with a computer, this instrument offers the general MIDI (GM Level 1) as well.

For Your Entertainment

Aside from some main changes above, the Casio CDP 235 review concentrates on other entertainment features, including:

Sampling And Playing

The sampling feature is an ideal way to create new and creative sounds. For instance, you are able to test a sound from a microphone and perform it on the keyboard.

Or utilize the sampled sounds to create music or play notes if you like. Even, you can add vibrato, reverb or other effects to the sampled sounds to play notes on the keyboard.

Audio Or Mic In Jack
