@Wain
The bit I'm talking about, to clarify, is a high part playing C#m for 2 bars and then B for 2 bars (when counting the bars I'm assuming that the song is in 6/8 not a slow 4/4). It comes in at 2:32 just as Thom sings "happen". It *sounds* string-like, even if it's not actually strings.
If you have any ideas of samples I could try, even to get close so I can tweak them, or maybe effects chains I could use, I would be really grateful.
