Electronic keyboards are often underestimated in music production. Nonetheless, they can help you understand much better how piano instruments work. That makes them as helpful as MIDI keyboards if not more. Casio has been recognized as one of the leaders in the manufacturing of quality electronic keyboards (alongside Yamaha).

Casio CTK 2400 Review 

Performance & Sounds

To start of, we believe that whilst this electronic keyboard is simplistic and limited in some ways, it also offers lots of features (possibly more) compared to competitors. If you’re someone who is just getting into playing piano, the CTK-2400 would be an appropriate choice. Indeed, it is perfect to have a quality keyboard at an entrance level price which has characteristics that will make you feel at ease with the functionalities of electronic keyboard. More specifically, the demo songs and featured sounds are qualitative and great to get started. The reason behind our choice to select the 1st version of the CTK Casio is that it’s not necessary for a beginner to pay more for a superior version (CTK 4400 or 6200) since this one is perfectly able to do the job.

Considering this electronic keyboard is centered for amateurs, 61 keys prove to be more than sufficient. We have also noticed that the size and the weight of the CTK 2400 is respectively smaller and lighter than the ones from Yamaha. However, the drawback is that the keys size are slightly less wide than classic piano keys.  This electronic keyboard is definitely designed for learners (only). Yet, it can be used for your music programs thanks to the USB/MIDI connectivity. However for those who have already experiences playing piano, it would be more strategic to go for another electronic keyboards from the CTK series.

Connectivity & Features

In terms of connectivity, the great thing with this device is that it has a USB MIDI connectivity, which is pretty unique for an electronic keyboard category. What this also means is that you will be able to connect it to any music production programs (FL studio, Logic or Garageband) you are using. In that case, this keyboard could be a really good deal since it already comes with certain built-in sounds. Casio has introduced a bunch of unique features. With this keyboard, you get the possibility to be accompanied with 110 songs (you will only plat the piano part). Moreover, the touches you play/are played are displayed on the LCD screen which can be useful when you want to learn about the name and positioning of notes.

After having tested the keyboard’s tutorial program, we have noticed that it is self-sufficient and is a good starting point for beginners. The video below demonstrates how you can start learning with pre programmed songs with the CTK-2400:

If you are not depleted in terms of musical possibilities with 400 built-in tones, 10 possible effects , 10 reverbs, 110 sound banks, 48 notes polyphony, 150 builtrythms, you also get a built in vocoder. The vocoder lets you capture your voice and noises.It blends sound over it depending on the notes you play on the keyboard to produce a synthesized symphony. In terms of features, we are a bit disappointed that the Casio CTK 2400 doesn’t offer touch sensitivity which is complicated if you want to learn piano the proper way. If you’re looking forward to mainly use the MIDI sequence, then it would be an undeniable choice ahead of many other expensive keyboards.

The great thing with this device is that it has a USB MIDI connectivity, which is pretty unique for an electronic keyboard category.

Additional Content & Versions

Casio offers different versions of the CTK that come with different types of bundles. There is a bundle with stand and headphone, a bundle with Samson HP30 headphones, stand, and interactive instructional software and a final Bundle with a stand, headphone and a Playground’s desktop software. Additionally, the Casio CTK 2400 comes with a little wire stand for your music, a great song book. Nonetheless, this electronic keyboard doesn’t come with a stand, or a damper pedal (which gives you sustain).

Furthermore, when buying additional, complementary items for your CTK 2400, you should make sure that they are manufactured by the Casio brand to be compatible. We really appreciated the additional content that is featured on this synth. As mentioned earlier, the window providing you with the title, the program, a representation of the whole keyboard, staff, the played note(s), a metronome, and two hands is very helpful for a beginner. Moreover, much like on the “synthesia’ software through which you find many playing tutorials on youtube, this electronic keyboard will play the demo song on the display.

How Does the Casio CTK 2400 Compare?

With 385 instrument voices, 100 preset songs and nine-step lesson function, the Yamaha PSR e253 61 keys is quite similar to the Casio CTK 2400. Weighing less than 9 lbs, this keyboard has the particularity to be very compact and portable. Moreover, running on batteries you can take this device anywhere with ease. This is useful, especially for lives performances.

Yamaha has provided a 32 note polyphony which is less than what is available on the CTK 2400. Unlike the latter, the PSR E253 has full size keys which is better to learn piano on the long term. Overall, through this electronic keyboard, Yamaha wanted to propose the same as Casio; let beginners learn piano easily. Either way those two electronic keyboards will be a great asset to progress into your music journey.

This 61 keys electronic keyboard is different from the former 2 keyboards because it comes with more bundles (stand, bench, headphones, and microphone). That is the reason that makes it one interesting to have a look at it. However, even though it offers a bunch extra products, the Alesis Melody has some downsides compared to the Casio and the Yamaha. Indeed, it has “only” 200 built-in sounds (with layer and split modes) and 128 accompaniment rhythms.

Nonetheless, compared to its competitors, the Alesis Melody is way lighter and portable (6.87 lbs). Moreover, just like for the Casio and the Yamaha electronic keyboard, Alesis has manufactured this device to accompany beginners in their journey to learn piano. Newcomers will have the chance to have 10 featured songs in three instruments modes (learn the rhythm in ‘One-Key’ mode; then get the notes in ‘Follow’ mode; finally, put the whole song together in ‘Ensemble’ mode.)


This Casio CTK 2400 review revisited a great keyboard for musicians who want to improve their playing skills. With the quality content that is included on this device, it is also adapted to music producers who want a keyboard which can let them experiment with musical ideas. Moreover its MIDI compatibility makes it usable with most popular music programs. It may be true that this model won’t satisfy more advanced musicians who look for a more complete product. Nonetheless, this is not the users it is destined to. The CTK 2400, is a simplistic, yet, sufficiently equipped keyboard to awaken a musician’s creative senses. This makes it a choice which won’t disappoint music enthusiasts who are not looking for the most performant keyboard, but one which will meet their requirements in a sufficiently gratifying way.
