Guitar Hero 5

Well, it happens that when I start playing, the notes are not activated, the buttons are useful but it is of no use to me if I cannot play because the notes, when passing, do not activate. Any solution? Should I activate something in the game or in the emulator? I really want to play this game (I use dualshock 3) (I have tried mmjoystick, xinput and dualshock 3)
