ATMO The fog

WARNING: Watch out when playing with the macros, 2 & 3 may cause crackling

Atmosphere/Texture thingy with some settings, but using slow LFOs with random delays in seconds instead of randomisation
No post-processing has been done, sound comes as in the preview
I suggest playing multiple notes at once to get this texture, play two notes very close to each other for it to drone
I also suggest using sidechaining if you use it as a background atmosphere for a non-ambient track
