actually I wouldn't go into details on how I came up with the settings during mixing for a few reasons.
1) I don't want people to tell me "hey that's the wrong method, it's not taught in sch, that's stupid" etc etc. my methods of recording and mixing were all almost self taught. and it works for my style of mixing, it works for people who listen to it so to each his own.
2) of course it took me ages and lots of trial and error to come up with these processing settings and all for them to become pretty much "tried and true". and yes no preset is fixed, for myself I roughly have a "vocal" customized preset, then I re-tweak them again according to the new vocalist's style of singing, the pitch range, male/female, genre etc. it's like your case of "asking for midi sequences".
i believe my case would be similar to joshua's or any recording mixing engineer here. we can guide you with a basic template on how your
"weapon" works. but it's your very own character that will define what works best for you in your mix? ("close range/medium range/long range?")
