Nope - I'm happy with my thoughts on it, and I'm not remotely interested in trying to find somebody else's curve to mimic - and even thought I record lots of show tracks that are as close as I can get to the originals, the original has vocals which will be prominent, and mine won't, so I suppose I could remove the vocals in Spectral layers and then see the visual result and mimic it, but I think that's hardly sensible. I understand your idea, and it just is NOT a way I'll ever use myself, or promote to anyone else. I just n' get my head around the mixing by visual approach. I push that fader until that source sits well. I'll drift in that chuffy guitar rhythm till it does it's job, but no more. With this weird system you're promoting - if you had say hi-hats and a rhythmic synth sound in the same space - you could get the curve with either fader having prominence. Mixing is about ears, and if your ears are not good enough, maybe it's not a good substitute. I bet I could mimic any response curve with a terrible mix. I do think that as a tool to check for oddities it could be useful but following somebody else's response curve is, to me, something I'm never going to do.
