  If playback stops part way through while transferring song data from your computer to your Casio Electronic Keyboard, digital noise from the USB cable or power cord may have interrupted data communication. Stop song playback, disconnect, and then reconnect the USB cable from the digital piano. Try playing back the song again. If the problem persists, quit the MIDI software, disconnect, and reconnect the USB cable. Restart the MIDI software and try again.
