I can't figure out how to make this sound

In this track Lancelot feat. Antony & Cleopatra - Givin’ It Up

@ 2:38 there is a filtered synth line that is being pitch bent up and down that I can’t figure out how to reproduce (not the pitch bending obviously, the actual sound itself). I can tell it’s got a lot of resonance on it but I’ve been playing around and just can’t get it…

There are drums, a sub bass, and the filtered synth thing I’m talking about, I’ve heard this sound before. Can anyone help me out?
