That's disappointing to hear, with the engineers at some big studios. Sounds lame. Maybe the budgets don't allow for anything more. Can't be very interesting to work as an engineer in a place like that, either.
Ideally, they would listen to the song, have a vision for the sound, and tweak amp and mic selection+position accordingly. Conversely, this is why I would prefer to have the individual mics as separate profiles as well, so I could make my own blend as suitable - since the profiles for obvious reasons cannot be done with my songs in mind :-). This is also why I'm interested in your upcoming AC30 pack, sounds like it will have ultiple mic setups to choose from.
...I'm also wondering if you were being sarcastic with your "else music today would be robotic and awfull" comment
