If you have a midi controller with some knobs and sliders, open your VI plugin and right-click on a parameter. If you see an option named "Midi Learn", move a knob or slider on the controller and that should take over the parameter control. Not all VI plugins have this option, but I know DB-33 and MiniGrand have it. Once you get something programed as you like, save the track as a Track Preset so this midi learn stuff will be remembered
