Quite a few posts in the wishlist mention sidechaining - sidechain for erosion, sidechain for eq, etc. It might be worth just having a single Live Device which is basically a "sidechain unit", which allows you to pass a filtered output to another device in the signal chain which only affects the sidechained sound, not the whole output. Kind of like Utility but with filter controls and a drop down menu to let you select which device receives the sidechain signal.
