After recording songs for four hours, lstening to them, good playback. Ready for performance . Then next session, one of them had disappeared. Started over, recorded again. Yesterday only one was left ! After hearing it once, it disappeared too ! I did not hold down the Recording button until "Delete" appeared. Phoned Costco in Kelowna where I bot it on Nov22 in BC. They suggested "customer Service in Canada". Instead a person from US answered who did not comprehend . So she referred me to this site. If this is a common probem, being unable to retrieve recordings, Costco will not want to sell defective keyboards. My former Roland did not lose recordings... I had hoped that Casio had improved. Sure hope you can help me retrieve the musical information.
