What bothers me about it is the philosophy behind it. Everyone who uses it allways talks about how it saves time and money. It sounds like it.
At the end of the day comping is just you playing and nothing else, so why would that be considered cheating? Auto tune is when you can't make or think of the sound or note you want in the first place and use a program to make it sound good.Any music that enters a computer is digital music - that means there are a million ways to tweak it. It's just tools. I bet your favourite artist - or their producer - uses it sometimes. I also bet EQ and other sonic sweeteners used to be considered cheating...I'm sure track comping was considered cheating.
