Hi there,

I just updated to O.S 1.3 but I REALLY need to downgrade to 1.2 'cause v1.3 won't let player 2 play .cdg files! This is very,very bad because of the silence in between .cdg files (I can't afford that in a live performance....) Please help me if you know something...Thanks

i thing;you can download from ketron.it and install os 1.2 to your mid jay

Yes, I did that but it doesn't undo the changes done by O.S.1.3!!!! I'm getting desperate....
