Hi, I bought a 2nd hand PX130 Casio Keyboard.The issue is that every time i turn it on i must reselect the piano, and retune it in A440. The keyboard doesn't automatically save the last selection of instrument.It always starts with "organ" and the tune of C key starts always in Ab. Is there a way to automatically save a new default, or at least to say "save the last option selected"?.Thanks in advance for any kind of help.
