How to recreate the synth?

Hey I dont know if this is the right place to put this, but Ive been trying to recreat the lead synth in the “DJ Nibc ft. Awa - Hold On (Don & Palm Remix)” and I was wondering if anybody had any ideas on how to do this? I got the general sound down but its the womping (or how to put it) attack that I dont really get how to do and what type of legato or anything I should have as it goes down one octave in the middle…



Any help would be most appreciated!



Thanks!
