Hi
Playing on my mp7 I carelessy hit a transpose LED to the right of 
the two octave transpose buttons and it fell through (i think its 
just a plastic cover cause the light is still going inside) so theres 
just a hole there. i can hear the detatched part rattling inside. Is it 
safe/easy to open and repair? Im not sure if anythings broken, it 
seems like it just became detatched. i bought my mp7 overseas 
so im definately trying to just open it an reattatch the part myself.

Thanks
