Overview

The Casio LK-240 is a home keyboard released in 2013. It is marketed primarily to home musicians.

The LK-240 has 61 synth/organ style full sized keys with touch sensitivity but no aftertouch. It has 48 notes of polyphony. It has hundreds of on board sounds including pianos and real world sounds, accompaniments and rhythms, and a sustain/damper pedal.

The LK-240 uses Casio's High-level sample playback sound system, a basic PCM-style sample engine used in entry-level keyboards. It also uses Acoustic and Highly-compressed Large waveforms sound source, offering efficient sample playback optimized for low memory with good fidelity.

It has the ability to record and play back user performances. It has built-in MIDI capabilities. It offers an on-board learning system. It has no built-in speakers which means you will have to connect it to external amplification and speakers in order to hear it. It runs from AC power.

The keyboard is a decent choice for children. It's very much an entry level model, making it cheaper but also with fewer functions or lower quality sounds than more expensive keyboards. It's a part of the LK family of instruments.

Description

At A Glance

The LK-240 illuminated keyboard represents independent learning and the opportunity to experience a sense of achievement. Just like during traditional piano lessons, the practice piece is divided up into individual sections of several bars and is learned section-by-section. The microphone provided can be easily connected to the keyboard: Now you can emulate the sounds of the chart hits or record songs using the sampling function. 400 AHL keyboard voices, 150 rhythms and 110 internal pieces ensure an exciting sound mix. Hours of fun instead of boredom!
