Here’s a tiny working setup! Yep, need to create refs/vars…everything has them. Either by clicking the + and searching for the right type, or dragging out from a related node, from the little pin you want a var of. Drag out from it, let go, on top of the long menu list it will say “Promote to variable”.
There’s more to submixes, f.ex sends, but this example is about changing a submix effect parameter live.
This bp references a specific sound just to have a sound. In reality, every sound that points to the same submix, will also have that effect affect them.
