I actually figured it out.. If anyone needs me to go into detail I can. But short answer, it's in the Parameter/Control Panel above the tracks (Top Left Hand Corner in the arrangement view). On the Control side you Edit the device you're using (Midi Controller/Keyboard) and when you select it, a window pops up where you can hit the Midi Learn Button and once you hit it, you move a knob, press a button or step on your expression pedal and then the control panel with show you have a control midi assignment ready for a parameter. You then can you the the Mouse Over or "recently touched" function to then assign your control to this parameter. Hopefully that makes sense.
