I’d say there’s some pitch-bending on the notes and an LFO, probably on the volume. I think the main thing is notation.
FL has ‘slide notes’ which make this kind of thing easier, if that’s what you’re using. Otherwise, I think most DAWs mandate you do it in the synth, so you’d need various instances of the wobble depending on the bending you’re going for. Start out by trying to copy the bassline notes, then apply the wobble, then apply the techniques to your own stuff.
Could also be a key tracking LFO on the volume, in which case massive would be a good synth to go for.
