Nice Touch and Feel

The Casio CDP-240 comes with 88 weighted keys, so it’s going to do its best to really emulate the feel of playing on a grand piano.  On top of that, the weighted keys allow you to select from three different weights, giving you the flexibility to amend your playing experience depending on how hard or soft you want to feel like you have to push the keys down to get a satisfying experience. 

The Casio CDP-240 is a portable digital piano, but unlike the Casio CDP-135, which weighed roughly 24 lbs, the CDP-240 comes in at about 42.3 lbs. 

And so, if you were interested in purchasing this instrument because you wanted to lug it around from gig to gig, you should know that it will weigh almost 20 lbs. more than the CDP-135.

Below, please take a moment to view some of the best selling digital pianos on Amazon, and see how well they stack up against the Casio CDP-240:

What Comes Inside the Box?

For less than $500, you get quite a lot of bang for your buck.  Along with the CDP-240, you can expect to receive a power adapter, a sustain pedal (SP-3), a music sheet stand, user manual, a stand for the piano itself, a bench to sit on while playing the piano, a mini audio cable, and two song books.

One thing I really like about the Casio CDP-240 is its Step Up Lessons system.  This being a very affordable digital piano, I really like how the piano has a system that does a good job at teaching you how to play.

While using Step Up Lessons, you’ll notice on the LCD screen on the front panel that there’s an outline of two hands.  As the music begins to play, certain fingers on the hands will light up, showcasing where on the digital piano’s keys (also displayed on the LCD) you should place your hands. 

Overall, this helps you learn about music notation and hand placement.  It’s a very nice and simple way for the CDP-240 to help you learn how to play the piano.

Noteworthy Features

When you play the Casio CDP-240, you also have the ability to learn over 100 built in songs.  On top of that, you can also use the CDP-240’s Music Challenges, which can help you further advance your skills. 

Essentially, you and the piano will play a game of sorts, as the LCD screen challenges you to play the same keys that it just played.  It’s a fun way to continue learning and practicing how to play the piano if you consider yourself to be a relative newbie.

On top of that, the CDP-240 features 100 demo songs and 50 exercises, for those looking for more incentive to learn how to play. 

You’ll get three lessons with a display to help guide you along with the song book—the latter of which is included in your original price of the instrument.  The books themselves include a wide variety of songs you can play—from the very easy to the more advanced.

Ultimately, you’re going to get some nice features with this piano, including things like sound effects, arpeggiator, external sound input, and recording functions, which can certainly be saved to an external SD card. 

An SD card is always a nice, handy piece of tech if your digital piano accepts it because you can load songs from the Internet onto it and input them into your computer; or record, save, and export the musical creations you make by unloading them onto an SD card.

You also get a USB port for MIDI interface with the CDP-240, as well. 

Sounds of the Casio CDP-240

This piano comes with 152 built in songs and 700 tones—so you’ll be hard pressed to become bored or unsatisfied while playing the CDP-240.  When it comes to tones, you can expect to find piano, organ, guitar, bass, strings, pipe, drum set and more. 

You get 16 watt speakers here on the CDP-240, which will provide you with pretty good external sound.  If you live in a home with one or more people that simply don’t want to hear you practicing Beethoven or Bach late into the night, you’ll be happy to hear that the Casio CDP 240 has two headphone ports.

So now, you can you practice the piano without making a peep.  And not only that, but another person can sit down next to you, plug in his or her headphones, and begin playing without disturbing anyone in your home. 

The 2 headphone inputs are always a great idea if you play alongside a teacher, for instance.  Now, your teacher can listen to and monitor your learning without disturbing anyone that’s in the next room.

Casio CDP-240 vs Casio CDP-135

The biggest differences that I immediately noticed between the Casio CDP-135 vs the Casio CDP-240 was the lack of a LCD screen and the inability to feature a recording function.

The Casio CDP-240 features both of these two items, but the CDP-135 unfortunately lacks them, which is at least in small part why the CDP-135 costs about $150 less than the CDP-240.

This, of course, will all be a matter of taste to some.  Instead of being able to confirm your feature selections using the LCD screen on the CDP-135, you’ll have to cycle through different options via the “Function” button.

And if you create a fantastic musical masterpiece, and you’d love to be able to record it and perhaps export it to an SD card to play for your friends or family later…well…you’re unfortunately going to be out of luck in that department.  The Casio CDP-135 offers lots of great options, but the ability to record what you play is sadly not one of them.

Conclusion

The Casio CDP-240 is a very nice digital piano that’s highly affordable.  Great for beginners but also suitable for players that are a bit more seasoned (but are also shopping on a budget), the CDP-240 is an noteworthy piano that’s worth considering if you’re in the market for a great piano that has cool features and a great built-in system to teach you how to play.
