I havehad a couple of opportunities to be a "recording artist" (popular music, not classical) and I have found that as soon as musicians find out the opportunity for "changes via edit" exists, they immediately discover a near-infinite number of "flaws" in their solos which need to be corrected!
So true. So goes also with artists who want to change the volume of one track in the mix by half of one dB, or move one note in a solo by miliseconds.
Perhaps my favourite quote from an ARSC Conference came in Philadelphia from Joe Tarsio, pivotal engineer for the "philly sound" of the 1970s: "Remember, automation was supposed to *save* us time!"
