Chordana Play

TOKYO, January 19, 2017 — Casio Computer Co., Ltd., announced today that it will release Chordana Play, a free app for smart phones and other devices. The app makes it fun for users to learn to play keyboard by displaying notes graphically in real time in the piano roll window. The new Chordana Play app is scheduled to be released in March 2017.

In 1980 Casio released the Casiotone 201, its first electronic keyboard. Since then, it has developed a series of original electronic instruments, including Key Lighting Keyboards, in an effort to encourage more and more people to play music. More recently, Casio has been developing free music apps. In 2013, Casio released Chordana Tap, which had chord analysis technology, and in 2015, it released CHORDANA TRACKFORMER, which can automatically compose electronic dance music (EDM). By focusing on both electronic musical instruments and music apps, Casio is aiming to bring the fun of music to an even broader range of people.

Chordana Play is a free music app developed with the vision of enabling people who have no experience playing an electronic keyboard to have fun, while also helping experienced keyboard players expand their repertoires.

Electronic Keyboard in the App Makes Playing Fun

The app can automatically play a variety of 50 songs, from pop to classical. As the song plays, the app displays the correct keyboard position for both hands in real time in the piano roll window. Thanks to this feature, even users who cannot read a musical score can have fun learning to play. Of course, users can play by touching the virtual keyboard, and they can go even deeper with the lesson function and scoring function.

App Can Be Linked with New Casio Electronic Keyboards

Chordana Play can be linked with the new electronic keyboards with an APP function. *1 The APP function comes with the new LK-265 Casio Key Lighting Keyboard, as well as the new CTK-2500, CTK-2550, or CTK-3500 Casio standard keyboards. These new keyboards will be released sequentially, with the first one in March 2017. Users can play along with the data from the app in real time, or they can save the song data to the keyboard. Furthermore, the key lighting system on the LK-265 keyboard can be used for lessons with song data sent from the app.

  • *1 A commercially available 3.5mm stereo mini-plug cable (stereo mini plug to stereo mini plug) is required.

Wide Range of Functions Enables Users to Make the Most of Their Musical Skills

Users can import song data (MIDI format) into Chordana Play. Equipped with original chord analysis technology, the app automatically generates a suitable chord accompaniment for the left-hand part. Like the built-in songs, imported songs can be displayed in the music score*2 and piano roll. Users can link to an electronic keyboard even when playing imported songs.

  • *2 Based on the MIDI file, the grace notes and other musical ornaments are omitted from the music score.
