A kind person who was passionate about ITB mixing mentioned the below: He said, "What's the point of using a digital hardware mixer in 2013 anyway? Show me one digital hardware mixer that wasn't out of date and virtually worthless 2 years after its appearance! Get a powerful computer and buy control surfaces to taste! Digital hardware mixers are a stupid concept and a waste of time and money. The world has zero need for a super short-living "tool" that offers solutions for issues that doesn't exist. They overcomplicate digital workflows like crazy, increases the potential for errors (digital interconnection synchronization is expensive and complicated), mess with your recall possibilities and none of them even come close to modern ITB setups with regard to ease of use, flexibility, quality and price! " What are your thoughts on what he said?
