Reply to Help mapping my livid ohm rgb

Hello, this is one of my first mappings so i am still beginner. Help would be greatly appreciated. Ok so in my mapping I have a fader and a knob for each effect unit to manually control the dry/wet and the fx parameters. I also am trying to make an instant gratification type grid of buttons for quick use of effects(in the same mapping). I know how to map the button grid the way I want it except for one thing. When I release one of the buttons in the grid I need the dry/wet for the corresponding fx unit and parameters of the the effects to go back to the value they were at before I pressed the button. PLEASE HELP
