In Godot's AudioBus system, you can add effects, and when you get an effect, you get a window with properties you can edit.
I went to see what Logic Pro did for something similar, and I was in awe, every effect has a custom and glorious UI.
I don't think I am going to get around to this before the 1.0 release, but I now have a new goal.
This is the pitch shifter in Godot and Logic Pro.
