Spare bedroom. It's a ridiculous post-production rig but it's got a bunch of software synths.
Nobody can pay for post-production anymore so that's not doing much. And generally, mixing other people's music is a game of "make it sound exactly the way it sounds in my head without me telling you what that is" so I'm no longer spending days tweaking on other peoples' music so that they can be annoyed I didn't guess their fantasy.
I've probably spent 20 hours getting someone else's shit hooked up to Pro Tools, which is on an iLok I own. Then another 15 hours trying to get his shitty-ass BehringerMidas to actually, you know, output on its output card. Knowing how to mix is fundamentally an adventure in pissing people off by providing them knowledge and tech support for dozens of hours at a time.
Pretty fuckin' over it.
