Does anyone have any idea what kind of synth is used in Every Teardrop Is A Waterfall?

If you're looking for a brand or make, it's almost impossible. Someone may have the exact same setting as one, but Coldplay, Eno, Dravs et al have probably changed the setting slightly whether with cut-off, reverb or what have you.

 

From what I've got and heard, I reckon you can get some similar-sounding things on any keyboard/synth. I'd recommend a Microkorg XL if you're thinking of buying one. There are many good leads on that that sound very ETIAW.
