Was just looking (with Josh) at how to remap the controllers on your keyboard like the modulation wheel or pitch bend to perform other functions in logic. He initially wanted to create some real time automation for a particular effect parameter and then record it in Logic (in the automation lane). We achieved this using:
Using Automation Quick Access – access with CMD + L
With a bit of extra youtube research I found this great video which clearly explains how to use this function to access any synth parameter with any controller (I would be most likely to use the mod wheel).
