Back in the olden days, when #Fairlight and #ProTools were still their own companies, I was trained on the Fairlight Constellation at a sister studio of one running Pro Tools. I came back to the Pro Tools one and was talking about how badass the Constellation was, including (but not limited to) this wonderful "rotate" knob on the panner. A traditional pan knob moves one dimensions at a time. There are also panning joysticks that enable to you two dimensions. The "rotate" knob pans around the circle. It's the same as spinning the joystick around the outer edge, but if you're starting with something panned closer to the center of a surround image, it's moving around a much smaller circle than you could do with a joystick, and if you're panning a stereo sound, it's rotating that stereo image around the circle, something I'd defy anyone to do very accurately with a pair of joysticks. I thought this knob was amazing, but one of my coworkers at the Pro Tools studio poo-poohed it, saying he'd had one of those on a console he used and thought he'd use it all the time, but he never did. I never got to use the Fairlight enough back then to tell him he was wrong, but I'm using it now and he was wrong. That knob is my new favorite way to pan things. It's amazing.
