Certified Trainer Wyatt Agard has released a free Rack for implementing different pan laws (level compensation for panning position) in Live. Inspired by an open request from Deadmau5, here's what Wyatt has to say about the Racks:
"Here's a set of three effects racks to deal with the problem. Each works the same way: the first macro of the effect rack should now be used as your pan knob. 64 is center mix. As you pan the rack will automatically boost volume as you move farther from the center. Depending on what console or program you are used to you would load the appropriate DB Pan Law Rack."
