    Casio continues the tradition or providing "class compliant" USB connectivity on Portable digital pianos. This allows Casio Portable digital pianos to be used with Mac or Windows computers without the need for downloading drivers. Class Compliant USB MIDI also allows Casio digital pianos to be used as a controller with the Apple iPad simply with the use of Apple's Camera Connection Kit.

    Casio’s CTK-2400 offers 48 notes of polyphony so you don't have to worry about dropping notes. Using the sustain pedal for multiple notes, playing big chords, adding rhythms and layering sounds can deplete the polyphony memory quickly resulting in dropped notes. When searching for a keyboard, take the amount of polyphony into consideration.


    The CTK-2400 has an impressive library of 110 built-in songs. Whether you are using the songs to learn with the Step Up Lesson system, or playing along with a song for fun, you will find greater choices to meet your needs. Compare the number of songs to other manufacturers and you will see Casio has the better value.

    Not only is the CTK-2400 a powerful keyboard but unlike other companies, Casio includes the AC adapter with all full sized keyboards so you can start making music right away.

    Casio's CTK-2400 includes 150 preset rhythms built into the keyboard. Additional rhythms expand your music composition, creativity and fun.
