Casio WK-245 Features

You can also turn off touch sensitivity for consistent volume regardless of playing technique. It has a bright backlit LCD screen to make navigation of settings and functions simple to do in any lighting conditions.

The keyboard weighs about 16 pounds without batteries, so it is portable. And because it can be battery powered, it can be played anywhere.


The Casio AHL sound system gives great sound quality with smooth waveforms. The keyboard has also 600 built-in instrument tones, a total of 180 rhythms with 10 user rhythms, and it is capable of 48 levels of max polyphony for layered sound.

Even professional musicians with an advanced keyboard setup at home may appreciate the Casio WK-245 as a portable musical workstation that they can easily take on the road, to a class, or anywhere else that they want to create and share their music.

Casio WK-245 vs. Casio WK6600

Casio WK-245 76-Key Touch Sensitive Keyboard with Power Supply
Casio WK-245 Review

The Casio WK-245 and the Casio WK6600 are very similar keyboards, since they are both 76-key workstation keyboards from the same company.

Both keyboards have:

  • 76 full-size touch-responsive keys
  • The Casio dual-element AHL sound engine
  • 48 levels of polyphony
  • 10 user-created rhythms
  • 10 types of reverb, 5 types of chorus
  • Layer/split keyboard functions
  • MIDI capability
  • Backlit LCD display
  • Microphone, headphone, and pedal jacks
  • USB port
  • And both keyboards are nearly identical in size and weight, with battery power capability

However, the WK6600 has a lot more features and capabilities than the WK-245, including:

  • 700 instrument voices (instead of 600)
  • 200 built in rhythms (instead of 180)
  • Equalizer settings
  • 100 preset and 100 user-specified DSP controls
  • Auto-fill and other music controls
  • 16 track song sequencer for up to 5 songs, with onboard song, track, and event editing.
  • 32 channel mixer
  • 50 user presets for registration memory
  • A pitch bend wheel
  • Memory card storage
  • Uses Apple’s Camera Connection Kit so it can connect to an iPad without additional drivers

In other words, although it is more expensive, the WK6600 has even more advanced and customizable digital features for songwriters, DJs, and composers than the WK-245.

As you already may have anticipated, the Casio WK-245 is better for beginners and new players and has the onboard lesson and learning functions beginners may need.

The Casio WK6600 doesn’t have any lesson features, and has more digital recording, mixing, editing, and playback capabilities for more advanced musicians who want to take advantage of the broader range of musical capabilities of their keyboard.

Both keyboards are solid options in their respective price ranges; it’s simply a question of how advanced the player is.
