Its a polysyth. I picked 2 sine waves and played around with the cutoff. After that i added 2 effects from the prophet: chorus and a flanger. To get that sound like the pad gets pulled i played set auxiliary envelope so the tone gets triggered when playing. I dont know how to do that in serum but google is ur friend. Im sure there is some kind of youtube video out there. Its actually just animating the tone (a note) starting low and going up.
