 It is the motorized slide potentiometer but you can see the cool thing is we can play around and then let go and get back to our preset position there thanks to the motorized fader. You can also go to other presets so if I click my encoder I can go to a different preset. I hit another one and these are just four positions that I've pre-programmed. I've set up my rotary encoder as a direct control there so you can see as I turn the rotary encoder I'm changing the position of the fader. I'm also using that as a stored position so now if I hit this four times it'll come back to this position. I have four saves so one two three four back to that new position. It is the motorized slide potentiometer.
