Dude then, I want to use the audios directly from the card, since I already had problems generating noise when I plug the cell phone into the keyboard.
I create the audio in Ableton LIVE, and export in 44100 24 bit, but even picking up the file and putting it in the folder that was created when I format the card on the keyboard gives the same error message. To contact Casio, here in my country to see what can be done.
