Thank you for your response! And how can you play wav files on the casio? I had exported a .wav file (16 bit) with audacity. I placed it in the
folder 'MUSICDAT' and named it: 'TAKE01'. First I turned the casio of, then I plugged the usb in the casio, turned it back on. next, I pressed the ' Audio recorder/media' button.
The name 'TAKE01' pops up, but then it says 'wrong file'. It won't work... I also can't record my songs. I hope it's not an issue...
