Many people, especially those are new to piano, feel torn between purchasing a digital keyboard or an acoustic piano.

The keyboard is a good alternative which is feature-rich, more pocket-friendly, and compact.

When you read this Casio CTK 4200 review, you do agree with it – right?

Why Should You Choose A Casio Brand?

To tell the truth, the piano never goes very cheap.

That’s why you should be considerative when it comes to purchasing decision.

Choosing a well-known brand is a quick and safe way.

Casio’s piano & keyboard has so far been one of the leading musical instrument brand of the industry.

For good reasons:

Affordable Price

Hardly there is any piano brand which can beat Casio for its price.

The company focuses on low-cost manufacturing while ensuring high quality as well. It means you can purchase a piano as good as Yamaha pianos at a surprisingly lower price.

Excellent Functionalities And Key Actions

That Casio pianos are less expensive than other plans does not mean you have to trade off the music quality.

In contrast, they secure reliable playing.

Casio even won the Annual MMR Dealer’s Choice Awards for Pro Digital Piano Line of 2017 and many other titles voted by customers.

With uncompromised sound quality and responsive key action, Casio pianos deliver the feelings of the authentic piano with realistic sounds.

Notably, the digital keyboard series earn big love.

They have a visual learning and practicing system to play and practice.

Compliant MIDI Connectivity

Even better, you can enter bass lines to the keyboard or edit drum tracks as wished.

The possible issue is that you need to have some knowledge about the MIDI process to make it quick and proper.

Thankfully, the Casio CTK 4200 Manual is available for your reference at any time.

Power Supply

Casio CTK 4200 digital keyboard uses 6AA-size alkaline or zinc-carbon batteries which can last for nearly 3-hour continuous operation on alkaline batteries and 2 hours more on zinc-carbon batteries.

The power adapter is included in the package.

What We Like

  • Portable and touch-sensitive keyboard
  • Rich in tones, rhythm, and notes for better practices
  • Decent sound quality
  • MIDI connectivity
  • Affordable price with headphones stand, and supply power included
  • Built-in Lesson System – extremely good for beginners

What We Don’t Like

  • The non-weighted keys are useful on the one hand to make the keyboard lighter. But, the players might feel a little bounce back when it comes to the acoustic piano.
  • Week stand that might cause unexpected falls and damage the keyboard
  • Easy-to-broke headphones. Some reported about this issue, so check the headphones carefully on arrival of the package.


Q: Is there sustain pedal in the package?

A; Many players want the keyboard to have a sustain pedal so that when they press the pedal, all the damped strings are sustained.

Accordingly, the strings vibrate freely, and all notes continue to sound until the release of the pedal or the natural stop of vibration.

Thankfully, Casio CTK 4200 does support several pedal effects for you to choose from.

To know more about the settings, please go to page E-17 of the Casio CTK 4200 Manual.

Q: Casio CTK 4200 vs. Yamaha PSR e343, which is better?

A: When it comes to digital keyboards, almost all first-time buyers put Casio and Yamaha under the serious weigh.

These two leading brands have different advantages. Here we focus on the Casio CTK 4200 and the Yamaha PSR e343.

At a glance, they have similar specifications. The Yamaha PSR even has fewer voices and rhythms than those of the CTK 4200. Yet its price is much higher.

This is because the Yamaha PSR has a better speaker system and recording features. Hence, the sound quality is higher.

All in all, the Casio CTK 4200 is better in price, and the Yamaha PSR e343 is better in sound.

Q: Should I Use The Touch Response Function?

A: The Touch Response is another excellent addition, yet it is more suitable for professional performance.

At the first stage of using the CTK 4200 keyboard, this feature is not very necessary. However, you can practice with it once your skill is improved.

The touch response adds a certain feel, rhythm, and dept into the pieces of music so that the sound seems far fetched.

Besides, you can understand the keyboard and piano better.

So, try this exciting feature later.

Q: Can I hook the keyboard to personal devices, such as my iPhone?

A: Yes, you can.

As above, Casio CTK 4200 supports the USB MIDI port. If you want to connect the keyboard with your MP3 sources like iPhone, buy using 1/8″ stereo jack.

Get one side of the stereo jack to that of the headphone jack of the keyboard while plugging the other end to the PC’s line in.

Q: What if the plugged headphones get no sound?

A: In case you have already connected the headphones to the keyboard, yet nothing happens. You need an adapter and make sure its connection into your Casio CTK 4200.

After reading this review and you feel a portable keyboard is not what you need. Why don’t you take a look at the CTK 7200, a home keyboard or the CTK 6200. It’s a good option to consider.
