Improved sound quality and keyboard feel

High-quality sound source!

CASIO keyboards use the high-quality AHL sound source, which is pre-programmed with digital samples of actual musical instruments. Students can develop a keen ear for sound through the high-quality sound of fine acoustic instruments.

Rich expressive power!

Sound output changes according to the amount of pressure applied to the keys, just like a piano keyboard (Touch Response), making possible richly expressive performances. Furthermore, the piano-style fingerboard provides a realistic performance experience.

Tuning in hertz is possible!

The tuning feature specifies the frequency of the A note in hertz, a standard frequently used for tuning acoustic instruments. You can change the frequency in 0.1Hz steps.

200 built-in tones and 126 rhythms!

The keyboard has 200 built-in tones, including piano, horn, and stringed instrument tones, and an Auto Accompaniment function with a selection of 126

Specifications for music education

The Layer function is for mixing two types of tones, and the Split function is for splitting the keyboard into two sections: one for a main (high range) tone and one for a split (low range) tone.
Recorder is an easy-to-operate function for recording performances.
The keyboard has pre-recorded demo songs in various musical genres for music enjoyment and appreciation.

Supports headphones for individual practice

When students use multiple keyboards for individual practice in the same room, the use of headphones enables each student to concentrate without distraction.

Metronome feature for practice at the correct tempo

The keyboard has a metronome that produces various beats, including four-beat, three-beat, and two-beat meters. In addition to piano practice, this feature is useful for practice keeping time in a variety of musical situations, such as choruses and ensembles.
