I’ve used the D Control in the video before (attached to a Pro Tools HD3 system), and I’ve done recording projects that used more faders than were available.
Those things are a freaking gift from god (or whoever paid for them) when you’re working on a mixdown. Like…the type of thing that takes hours with a mouse takes minutes with those things.
Seriously.
Now, they’re ridiculously overkill for a bedroom producer, since you could buy two very nice cars for the price of one of those things. But, there are reasonable 'budget" options that are just about as good for that application: the SSL Nucleus stands out as an easy choice, as does the Euphonix stuff. Not cheap by any means, but if you’re actually doing mixdowns on your own and value your time, they’re worth it. Even a Presonus Faderport can make a huge difference.
So, basically my answer to the OP is a resounding “yes, it’s necessary.” The fact that you don’t do anything that would benefit from it doesn’t mean the product is useless or even overpriced. If you’re actually running a studio, $80,000 is a steal for what those consoles do.
I’m not sure I get the point of that. Most artists don’t interact with D Controls at all…or anything else the studio spends a fortune on other than microphones and maybe a collection of big instruments that are inconvenient to travel with (pianos, drum kits, guitar amps, etc.).
It’s not for the musicians…it’s for the engineers who see several artists in a day, many of which either suck or aren’t the engineer’s cup of tea. Expensive recording equipment does give better sounding recordings…but a lot of it isn’t made for that…it’s made to save time.
If you were getting paid 5-6 figures to mixdown an album from an artist you didn’t like (I’ll go with Bieber to illustrate this point), would you rather spend several hours on each song setting levels and drawing automation with a mouse or get fast with an $80,000 console so you can get at least a rough mix inside an hour?
That’s what they’re for.
Plus…vagus mode looks pretty cool. I’ll never forget the day we used an HD system with Genelcs to watch youtube videos with the console in vegas mode. Why? Because it was there.
