We are expecting so things will need to be quiet in the house next year and I want to the have the option to mix/track on them.
Congratulations, in our experience and in talking to friends, don't go overboard on the quiet or you will have a baby that can't sleep around activity. Our kid would fall asleep with a smile when he heard Garcia's guitar, (babysitter + fussy 3 month old + Garcia album he hadn't heard = sleep), he also showed an early preference for Garcia to Zappa. We'd take him to parties, and when he was tired, he'd crash right in the middle of the party.
Now he's 15, likes Jackie Greene, Ryan Adams and Neil Young along with a host of newer artists. I've burned him out on the Dead, but that's fine. You shouldn't like all of your parents music.
