HTSL Freeform Hardcore Wahwah sound

The best way I can describe this sound is the “wah wah” sound found in a lot of hard dance and freeform hardcore tunes. I found a decent example on Youtube:

At 2:00 in you’ll hear the sound start to get introduced. It sounds like a high resonance filter with the cutoff on an LFO. But, I’m not sure what the underlying sound is. Anything I come up with sounds too chirpy, like a dang bird or something.

I don’t necessarily need a video tutorial but if anyone could explain it here that would be awesome. Or if this has been discussed before, please point me in the right direction.

Thanks! I’m loving the tutorials here at SA by the way, they have take me to the next level.
