I've only had a chance to listen to it a couple of times but to me it doesn't sound like anything that you have to program yourself. Most of the synths you've mentioned have sounds of this type as presets. Just check through all of your available string sounds and I'm sure you'll find something that will do the job.
All I'm hearing is two string/ hybrid string sounds. One is played like a slow sustained pad and another is played in a more percussive fashion. So find one string-like padsound and hold the chord. Play another, brighter string sound over the top and you're done.
Add a beautiful sax solo and you've got it.
