One thing you might learn is that the first thing to do when you find that you've dug yourself into a whole ... is to STOP DIGGING.
Nobody with 15 - or even 3 - years of genuine recording experience would ask the kind of questions you do. Certainly not if they had been paying any kind of attention. There are certain things you would just pick up by being there, nahmean?
Think about it: You want people to respect your opinion on a recording interface when you've demonstrated that you really don't even know what you are doing - yet - with how to setup a mic for recording vocals, or "what order to do things when mixing down vocals" (as if there is some set order - silly question), or whether or not to normalize ... what were you doing for all of these suppose 15 years of your experience?
We're all here to help each other in one way or another ... just tone down the unearned swagger and you'll get along better (and learn more in the process) that way. There are too many people - like me - with 30+ years of professional experience on this board, so you can't front and get away with it.
