Filter: Low Pass, 24 dB. Cutoff around the middle. Decent amount of Res to lighten up the bottom end and push out some mids. Key tracking enabled so that the lower bass pitch isn’t brighter than the upper chord pitches.
Chorus: this will do most of the work. Go full mix to get a nice wide sound. Set the Rate pretty slow (I liked it around 0.15 Hz). And set the depth so that it’s wobbling a bit, but not over the top.
The pad starts with what sounds like 3 notes: A low F#, another F# one octave above that, and an A on top of that.
