CASIO introduces its new Casiotone key-lighting keyboards, the "LK-550" and "LK-350," which are designed to make playing easy and enjoyable by guiding users with illuminated keys. The LK-550 is available in two colors: black and white.
Both models feature CASIO's Key Lighting System, which illuminates the next key to be played in red in time with the song. Even those who do not read music can enjoy playing by following the illuminated keys. Practice-support features, including Easy Mode and Step-Up Lesson, help beginners learn at their own pace.
The higher-end "LK-550" features new "Brain-Training BGM" and "Brain-Training Karaoke" functions based on joint research conducted with the University of Tokyo's Research Center for Advanced Science and Technology. In addition to playing, users can enjoy listening to music and singing for a more varied musical experience. The LK-550 also features 600 tones powered by CASIO's AiX Sound Source and supports the "Song Bank Plus" app, which allows users to add and enjoy more songs.
The "LK-350" offers a streamlined set of features, with 400 tones and 120 built-in songs. It also comes with a microphone, allowing users to enjoy singing as well as playing and making it an excellent first instrument for children. From guided practice with illuminated keys to singing and simply enjoying music, these new key-lighting keyboards offer an easy and engaging way to experience music.
