I downloaded an addon for Union Pacific Big Boy, and it turns out that the whistle is completely horrible. The sound is cool and it’d be fine if it stopped sounding when I let go of space, but it doesn’t. So I downloaded a file for Big Boy's "actual" whistle which stopped sounding when I let go of space, but it sounded horrible. So I would like to know how to make my own whistle so I can stop asking people for whistles when I want one, and finding bad ones when I search for them myself. If anyone could tell me how, I’d like that. Thanks!!!
