also searching for that patch
so that high soaring string synth sound has been around for a while.
it's on the Cure's "Just Like Heaven" - the descending melodic line
David Bowie - "Ashes to Ashes"
Gary Numan - "Cars"
so many more.
i'd be surprised if Coldplay wasn't using a patch that emulates or reproduces the classic synth.
but which one? still searching.
