Not sure specifically for that example, but I've had some success making similar pads using granular synthesis and/or good reverb/delay plugins like QuikQuak Fusion Field (really lush reverb) or SoundToys EchoBoy (a lot of Echoboy presets have a lot of modulation which helps create nice movement). Sometimes I find it's best to use mostly the wet signal and very little dry, and then resample so you have more control over it.

I can't remember where but I think I read that Burial mostly samples for his pads (and everything in his tracks, really)--so I wouldn't count on getting the sound out of any of the usual VST synths very easily....but Omnisphere is also amazing for pads like this.

There's definitely some very good layering involved too on his part--he sampled the vocals from a video game soundtrack https://www.youtube.com/watch?v=eUimcNyLU6Q

On the point about the granular synthesis though, you can take the smallest snippet of sound and run it through one and have an awesome randomly modulating pad without any reverb needed (which means you have a lot more control over the envelope of the sound). I use the monolake granulator for max for live. the demo video shows what I'm talking about pretty well: https://www.youtube.com/watch?v=9pn_b7OUO6I

I'm sure that the actual synth without effects isn't a big deal.

• Try creating a synth sound and loading it to a sampler.
• Get creative with reverb and delays.
• Modulating filters can make the pad sound alive.

A lot of the nature of this atmosferic sounds come from dub-techno.
This might help you.
