BTW, Casio instructed me to select the "Audio Recorder bottun (to get a solid red light) then select the "Song recorder button and select the song that I wanted to record. I inserted the USB Flash drive into the drive, but I was unable to get to the screen that would allow me to select what song I wanted to transfer to the drive. I xould get both lights to illuminate, but I couldnt select the song. You have to, according to the instructions, hold down the function key then select "Song Recorder." That move brings up the songs you have recorded on the machine. I could not perform those functions together.
