How to a Create Certain Smooth Pad

[amakarise]

Hello All,

I'm trying to figure out how to create this specific type of pad (or perhaps pad/strings?) sound. I've played around with a few different plugins (Alchemy, Absynth, etc), but I can't quite seem to get it. It's very smooth, not too bright, kind of airy-ish....

I have YouTube links to 3 different songs so you can hear exactly what I'm talking about.
Please skip ahead to the time frames I listed (if you want)

If you know of any patch within a plugin that sounds very close or is dead on, please mention it as well.
I currently work with Logic Pro. Thanks!
