Casio CDP-240 review: Why should you buy it?

Decent touch and feel

The Casio CDP -240 is a digital piano with 88 fully-weighted keys. This is a good start to mimic the touch of a real piano. More important, the weighted feature means that you have three different pressure responses from each key. This amplifies your playing expression according to how hard or soft you hit the keys to get the sound you are looking for.

The CDP-240 is a portable model, but not as portable as the CDP-135 with its 24 pounds, but weighing about 42 pounds.

So, if you are planning to buy this model to carry it around from place to place, you must consider that it has almost 20 more pounds than the old CDP-135.

What Else Comes in the Box?

You get a lot of accessories. Apart from the keyboard you will find in the box a power cord, an SP-3 sustain pedal, a stand for the sheet music, a manual, a stand kit, a quilted bench, a mini audio cord, and two sheet music booklets.

One of the greatest features of the Casio CDP-240 is the Step-Up Lesson mode. For such an economical product, it’s amazing that it has a mode that actually gives you piano lessons.

When you active the Lesson mode, you will see displayed on the LCD screen on the main panel an outline of two hands and a keyboard. As the music plays, some fingers of the hands will light up, showing you the keys that you must press.

In general terms, this is a help when learning music chords and hand movement. It’s a fun and easy way to learn to play the piano on your own.

Remarkable Features

The CDP-240 also has more than 100 inbuilt songs to learn. Moreover, it also features the CDP-240’s Music Challenge, that will encourage you to improve your abilities.

Basically, the keyboard plays a part, and the screen encourages you to try to play the same part the piano just played. It’s a cool method of learning and improving your playing especially if you are a beginner.

Moreover, this keyboard includes 100 inbuilt songs and 50 exercises, for students who need an extra boost for learning.

It has three lessons which are displayed to guide you through the sheet music book, which comes with the piano at the standard price. The said books have a varied collection of themes to play that are listed from the easiest to the hardest.

Finally, you will get a few great functions with this keyboard such as sound effects, arpeggiator, input jack, recording mode, and captures can be stored in an external memory card.

It also has a USB port to connect the CDP-240 to your MIDI devices.

Sound Quality

This keyboard features 152 inbuilt songs and 700 voices. So, it will be difficult to get bored or loss interest when exploring the CDP-140. In terms of voices, you will get pianos, organ, guitars, bass, strings, winds, drums and much more.

The piano has 16w onboard speakers that give a fine-quality sound emission. If you live with a partner or with your family and you’re afraid they just won’t be happy to hear you playing Schubert or Schumann late at night, then you will be glad to know that the Casio CDP-240 has two audio outputs where you can plug in your earphones.

Well, now you can play in absolute silence. But you can also invite someone to hear your playing sitting next to you with his or her headphones, without annoying the rest of your family.

The two audio outputs are excellent for example to play with a teacher. This way, the teacher can hear your playing and play along without annoying anyone else in the house.

Casio CDP-240 Vs Casio CDP-135

The first advantage I saw the Casio CDP-240 has over the Casio CDP-135 is that the latter lacks an LCD screen and the recording function.

The CDP-240 has these two features. The lack of the in the CDP-135 is one of the reasons why its price is almost $150 lower than the CDP-240.

This could be a minor issue for some users. They won’t be able to see their options displayed on the screen in the CDP-135, but they will have a function button to cycle through its several features.

And if you happen to compose an amazing piano sonata that you would like to record it and maybe transfer it to a memory card to enjoy later with your friends and family, well, it’s a shame, but you won’t have the chance to do that with the Casio CDP-135. It has many cool features, but a recording function is regrettably not one of those.


The Casio CDP-240 is a real nice electric keyboard at a very affordable price. Perfect for starters but also decent enough for amateur and mid-level pianists (that care about price), this keyboard is a remarkable product definitely worth your attention if you are shopping for an awesome piano with great features and an excellent inbuilt lesson system that helps you through the learning process.
