Sound montage? :)

Hi guys. I have a minigun and 3 sound fx. Minigun start, shooting loop and minigun stop sfx. How do I set it up so that the start fx goes once, then shooting loop keeps looping as much as needed and when I stop firing, the stopping sfx would play?
My minigun is not animation driven, its a static mesh with local rotation, so I can’t just throw appropriate sfx into animations. I try to stay away from Blender animations to unreal nightmare as much as possible.
