I just bought a Casio CTK 3500. I would like to play on the keyboard itself and save that data in the song bank. The Chordana play app only lets me download other files . All I want to do is save what I have played. Can anyone give me any hints. I have read the manual and don't see where it allows you to save what you have played even though the song bank has room for 30 user files. I DO NOT want to load other midi songs in. I simply want to record what I play directly from the keyboard and then have the opportunity to review or edit later. Can anyone help ?
