An obvious thought, but for the record (no pun intended), a great deal of it is about efficiency. If I can copy and paste a vocal from Chorus 1 into Choruses 2 and 2, that lets the singer go home earlier and lets me go on to creating another song. (I was first able to do this with my trusty old VS-1680, but it was a little clumsy, and the resolution was not perfect: sometimes things were a few ticks off.) Despite all the debate about Melodyne, from a practical and human standpoint, it makes more sense to fix a note than to wear a singer out punching in and redoing parts, possibly losing the feel along the way and maybe breaking note B in the process of fixing note A. (A little imperfection live is OK, but on a record, it is memorialized forever.)
This same logic applies to many other functions and tools.
You guys may have different goals as artists and that is not only OK, it is highly desirable: we shouldn't all be in the same bag. For me, though, it is about songwriting; and anything that helps me focus on writing and arranging instead of mixing and fixing is good. If I were super rich, I'd spend all my time with a notepad and let my loyal minions tend to the tedious parts.
As always, thanks to all my Sonar buddies for these thoughts. It sparks my creativity to read ideas from my valued peers.
