Need some help creating this sound. Zedd- Spectrum (main synths)

[scrubblybear]

The sound can be found here http://soundcloud.com/scrubbly/zedd-spe ... -synths-no

I took it from the Zedd- Spectrum remix contest, It is titled "main synths" so not too sure what exactly it consists of.
It's quite a common sound just don't know how to get anything even similar to this. Any help would be great. Thanks
