Getting it right isn't always up to the player. Although in the current era of non-destructive editing, it's less of an issue. I remember in the 90s at a session asking to punch in one note. The engineer kept screwing it up so much that I had to redo the entire verse. A 30 second fix turned into a half hour. It was a DA-88 rig, so it would have been an easy thing to just set in and out points, but he insisted on punching by hand. It aggravated me even more because as an engineer, I used to punch in parts of a word in a vocal and nail it regularly. If the levels match and you have your timing together, no big deal. Beer and pot do not belong in the control room. Oh well, I got paid.
I like Pro Tools.
