Again: Remember that Clip gain and Event Volume is two different things… Both working on the waveform itself, pre “anything”.
And Volume Automation is a third thing, working/controlling the channel/group fader (post eq’s and inserts).
The Clip Gain as it is now, capable of lowering the volume only (admittedly not used it in C8.5). And with NO curves or breakpoints available, it is pretty much useless IMO. Hence my support to the OP.
