Who the Casio CT-X700 Keyboard is Most Suitable For?

kid playing piano

The Casio CTX700 is an excellent choice for a committed beginner. It has onboard learning and lesson capabilities, and keyboard functions to make it easy to learn the piano, and can also be used with a wide range of piano education apps. The sheer number of features, and the need to refer to the manual to configure many of the options and settings, make it a less suitable choice for young children, or people who just want to mess around with a keyboard.

This Keyboard is particularly good for committed beginners because these capabilities, features, and customization options are rich enough to continue to engage intermediate and even advanced keyboard players. It has the musical capacity to remain a valuable instrument for years of learning, rather than being a keyboard that a beginner will quickly “graduate” from.

 It’s also a great choice for more advanced keyboard players who need a more lightweight, portable instrument. The ability to customize settings, songs, and rhythms, and quickly store and retrieve presets, along with audio output capabilities, make this a good choice for small gigs and rehearsals, composing or experimenting on the road, or even from the couch.

Features of Casio CT-X700

casio keyboard




It has 61 full size, touch-sensitive keys that help players learn the hand positions necessary to play on a full-size 88 key or acoustic piano keyboard. Touch sensitivity reacts to the speed and pressure as you play, increasing the volume accordingly. These keys aren’t weighted, however, so the fingers won’t develop the same strength or technique necessary to transition smoothly to an acoustic piano.


The AiX sound engine and DSP processing provides excellent instrument tones and voices not just in the piano instruments, but enhances the sound of strings, brass, wind instruments, and even effects, for excellent sound quality and appealing tones across all the capabilities of the keyboard.

Keyboard layer functions

Keyboard layer functions allow you to play two instrument tones simultaneously with each key, while keyboard split functions allow you to play two different instrument voices with each hand.With all these options and settings, it can be a bit frustrating to need to frequently refer to the manual to explore and experiment with different options, but the ability to choose from one-touch presets, and store your own settings into registration memory will ease that process and make it faster over time.


X700 has a rich library of instrument voices, built-in rhythms, music and accompaniment styles. It also has a broad range of reverb, chorus, harmony, and other effects for customizing the instrument sound.


The keyboard also has a number of features to help beginners learn to play the piano. The Casio Step-up lesson system teaches songs phrase-by-phrase, chord-by-chord, or hand-by-hand, at your own pace, depending on how you prefer to practice. It has a melody suppression system that allows you to not only play the lead role in any song in the onboard music library, but can also suppress the memory of songs played through the audio input, so you can play along with all your favorites.


GM level 1 MIDI format and USB capacity are a great advantage in this keyboard. It allows you to pair the keyboard with tablets and devices, augmenting your ability to learn, record, mix, and share music online. The ability to add and store your own custom rhythms and songs, and record and playback your own songs on the keyboard, help with both learning and with performance.

Pros & Cons of Casio CT-X700


  • 61 full-size keys, touch sensitive keys give good range of musical capabilities and expression
  • AiX sound engine and DSP processing provide excellent sound across all instrument tones and effects
  • It is lightweight and portable, and can be powered with batteries for additional flexibility
  • Keyboard layer and split functions allow you to more fully explore overlapping sounds and instrument voices
  • 600 tones, 195 rhythms, 310 music presets, 100 types of arpeggio, and a wealth of acoustic options and effects allow players to explore any music style or instrument sound they want to, and customize it however they choose
  • Transpose, tuning, and octave shift functions give even more flexibility, and are particularly useful when playing along with pre-recorded songs or with a band
  • One touch piano/organ button, one-touch settings, and registration functions allow you to quickly get back to your preferred settings without navigating the onboard menu
  • 160 song library provides a wide range of options for beginners to learn and practice, but you can also add your own songs to the library, play your favorite songs through the keyboard, or even record and playback your own performance
  • The Casio Step-Up lesson system, built-in metronome, on-screen chord guide, and other features help make it easy for beginners to learn, practice, and grow their skills as players
  • Industry standard GM level 1 MIDI with 15-channel multi-timbre receive, along with the onboard USB connection, allow your keyboard to interact with a wide range of software, apps, and services that expand your ability to learn and practice, or record and mix, or share and promote your music
  • Headphone, audio in, and pedal ports give good room for expanded capabilities over time as your skills grow and develop


  • Keys aren’t weighted
  • The sheer number of features and options require a lot of pressing numbers into the display, which requires a lot of referring to the user manual, particularly in the beginning
  • Given the number of voices, rhythms, songs, sounds, and arpeggios, along with chorus, reverb, layer effects, and the potential for pedal effects, it would be better to have greater polyphony. Complex, overlapping chords and compositions may exceed the limit, and may cause some sound clipping. However, 48 is also fairly standard for a keyboard in this price range

If you’d like to check out the nitty-gritty of the Casio CTX-X700, here’s a link to the model’s manual:


An Alternative Product to Consider: Casio CT-X700 vs Yamaha PSR-E363

Yamaha PSR-E363 PKS 61-Key Premium Keyboard Pack with Stand, Headphones & Power Supply

From the similarity between the devices, one might suspect that the Casio CTX line is aimed to compete with the popular Yamaha PSR line of keyboards. The Casio CT-X700 is extremely similar to the Yamaha PSR-E363. Both keyboards have:

  • 61 touch-sensitive keys
  • LCD displays
  • Battery power capacity
  • 48 levels of polyphony
  • Keyboard layer and split functions
  • Melody suppression
  • Pedal and audio inputs
  • Metronome
  • Tempo, transpose, and tuning controls
  • One-touch piano button
  • Onboard lesson tools
  • Registration functions
  • USB capability

The Yamaha PSR-E363 has a few advantages over the Casio CT-X700:

  • 26 types of harmony vs 12
  • 150 types of arpeggio vs 100
  • 9 slots of registration memory vs 4
  • Duo keyboard function (virtually splits the keyboard in half, so two players can play side-by-side)

And the Casio CT-X700 has some clear advantages over the Yamaha PSR-E363:

  • It has 195 built-in rhythms
  • It uses MIDI recording rather than a proprietary file format
  • It has the ability for users to create, store, and retrieve custom rhythms and add songs to the onboard library.
  • It comes with the necessary AC power adaptor

However, the Casio CT-X700 simply has more capacity than the Yamaha PSR-E363:

  • 600 instrument voices vs 574
  • 20 types of reverb vs 12
  • 10 types of chorus vs 5
  • 6 types of master EQ
  • 310 music presets vs 165
  • 160 songs vs 154
  • Capacity for 6 user-recorded songs instead of 5

While the Yamaha AWM sound engine is very good for a beginner piano, there is no doubt that the Casio AiX sound engine is an improvement. Ultimately, the Casio CT-X700 simply sounds better than the Yamaha, and has more features, for the same price.

 While it is still hard to find, it may also be worth looking at a Casio CT-X800. It has all the features of the CT-X700, along with a little more memory, improved two-way USB connectivity, and a pitch bend wheel for just a slightly higher purchase price.

Video: Sam Ash Music’s CT-X700 Review


Casio’s CTX line is precisely aimed at the features, functions, and capabilities that beginner and intermediate musicians are looking for in a portable keyboard. X700 has a great sound, robust construction, rich feature set, and expansion capabilities to be the only keyboard you need for years to come.

casio 61 key

It also has the advanced digital features that acoustic pianos don’t have, including a wide selection of tones, rhythms, polyphony, and even simple volume controls to make it easy to live with. 

Recording and playback, transpose, and split keyboard functions offer a range of possibilities and capabilities that invite learning and exploration, as well as affording unique opportunities for growth and expression.

Most keyboards offer a fraction of the features at more than double the cost. This powerful, versatile, handsome digital console keyboard simply cannot be beat in its price range, and is a fantastic choice for piano lovers everywhere.
