Expand the keyboard’s store of built-in songs
Use an audio cable to transfer 50 built-in songs from the app as well as songs downloaded as MIDI files and save them in the keyboard. You can then use the saved song data with the keyboard accompaniment function to enjoy the Step Up Lesson feature.
Songs stored in the keyboard may sound different from original built-in songs.

Practice playing on the smart device screen
Another fun feature is the ability to take 3-step lessons on the smart device itself using the virtual keyboard that appears on the screen. You can confirm the chords, melody and finger timing visually on the screen, while also using the scoring function to help you master the song. The 50 built-in app songs and your downloaded MIDI file songs are all available for use in your lessons.
 

LEARN YOUR FAVORITE SONGS
Connect to your iOS or Android device to use the free Chordana Play app, which uses the CTK-2500’s display to show you how to play your favorite songs. Just download your favorite MIDI files, connect your device's headphone output to the CTK-2500's audio input, and explore an endless library of music. You can even transfer songs to the keyboard, and learn them when your device isn't connected (some file limitations apply).
