Question: I've spent a frankly embarrassing amount of time trying to figure out how the volume faders are scaled in the Cockos plugins (as well as the "Max precision at +0 dB (4.0)" volume fader shape preference in Reaper). I think I've cracked it: desmos.com/calculator/tgxb1s04jk My question is: Why? Or perhaps: How? I've never seen anything like it. It's magnificent.

    the default is modeled after a PGF8000 taper, I think, I can't find the reference, but it dates from here https://forum.cockos.com/showthread.php?t=78197 (I think it's more or less val^3+val^6 then converted to dB, and partitioned according to where the center pos is.)

    I'm quite certain you're referring to the "Default" fader shape rather than "Max precision at +0 dB (4.0)". Just noticed btw that the faders in the native Cockos plugins obay the settings chosen in the TCP preferences page, that's neat. Don't get me wrong, x^3+x^6 is a lovely taper but it's nowhere as unique as the one I'm talking about.

    ah, that's just x^4
