They have this built-in already - unfortunately, only visible in the meter bridge in the MixConsole. Enable that, and you will see… Its a shame they can’t/haven’t been able to bring this to the Channel meters yet… I have requested it before (Cubase user here…!).
BTW - see how elegantly this works in Studio One; and the way they’ve made an SDK extension available to 3rd parties, so others can take advantage of the functionality too… For example, FabFilters new Pro C2 (vst3 editions only) works, just like the stock Presonus comp (on an insert). I don’t have it myself… just reading off KVR folks posts…
It looks like a useful visual cue, so,
