What does Vegas mean by punch in recording, exactly? How 
would you do a punch in recording? I can't find anything in 
the book, except to record on another track and then 
edit(paste)it into the main event track. I was hoping it 
would be more traditional like setting the point where you 
want to record and then being able to start BEFORE the 
actual recording would start, to give the talent some time 
to find the groove. Any help?
