I refuted it, actually. Your assertion is that compression is there to 'fix some flaw in the signal'. Dynamics are not a flaw. Adjusting a signal's dynamic range to fit within a certain restrictive 'box' like radio, or media like vinyl or a CD is not 'fixing a flaw'. A flaw in a signal would be a click, or a pop, or a buzz... all things that compression will ENHANCE rather than correct.
My assertion is way more than that. This thread is about PARALLEL compression. I may have use “flaw” in lack of a better term; but that’s pretty clear in my comment.
But since you’re insisting; I’ll insist that you should re-read the article you linked.
“They keep our mixes from clipping, smooth uneven dynamics,…”; “
Peaks in the program audio could cause the radio signal to become over-modulated, distorting the broadcast.”; etc…
It lets very clear the original use of a compressor; and most of all it also puts it very upfront, the frivolous hype on parallel compression. All those legendary compressor mentioned, let very little way to justify parallel compression. Apart from compressing the signal each their on way, they also amplify the signal leaving their signature coloring to the sound.
Also, if you look closely, you will notice that many; if not most; have “Amplifier” in their names; some just yeild the suffix A. So basically we are talking about gain staging.
Also, in that detailed essay they mention a producer that I’m found of: Tchad Blake, and yes, he uses the Level-loc aggressively and in all its glory. Ironically he surely makes use of parallel busses for his purposes, still, we’re not in the subtle refined tone layering, you seem to advocate.
So, no, there is nothing wrong with complex chains, in which one can rapidly lose hand on what’s going on.
I much prefer make use of the natural compression and harmonic enhancement of a good pedal format pre-amp, and leave the compressors do their thing.
ps. The toggle switch on the Seymour Duncan SC is not a multi-band. It a band selector. Normally, when one refer to multiband it’s implicit there are at least two compressor. One for each band, and those bands are often variable.
