Hello, I am hoping someone could please help me, I want to change the annoying metronome sound in Cubase sx3 .

I go into the transport option in the top task bar and go to metronome setup and can change the sound by triggering off a sound through a vst instrument via midi, but I have made a cowbell sound wav file that I want to load in so I don't have to trigger via midi. But whenever I load the cowbell sound in nothing plays back at all. Would anyone please be able to help me with this issue?

Thanks Damo
