Octave too low

[PeteAnica]

I have a PSR S900 and downloaded some songs from the internet.  They are stored on a USB stick.  When I play them they all play in a very low register...at least an octave or two lower than normal.  I believe they are midi files and I have had them for quite some time.  Originally they played correctly but now play low.  Is it a keyboard setting which I can change?

Many thanks

Pete

Try using your TRANSPOSE keys on the keyboard and use the (+) one to raise the midi to a higher key.
