Help - Recreating a pad/chord sound

[satyr32]

For weeks I am trying to recreate this deep, wide pad/chord sound that runs through the whole track.

The closest I could get is with a bell wavetable, a ton of chorus/unison, reverb a bit crusher (which I think is used) and stereo imager as well stereo eqd white noise with different filtering. But it is still too far from the original.
Also I have no idea which notes are played.
Has anyone an idea how this sound could be made?
