Saws and noise, put through a phaser. Put your saw waves at different octaves (I got fairly close with 3 saws - one at pitch, one an octave lower, and one an octave higher), and mess with the phaser parameters.

Phase modulation in massive is not phasing, it's digital FM.


Check the FX section, bro. There's a phaser there.

Well, a large part of it is the actual notes in the chord.

I might be wrong about it being multiple layers, and it might just be one very slightly detuned supersaw playing a very full chord, but through a phaser with no rate and around 40-50% depth. Looking at the spectral view of the chord, it looks like it's modulating between two C minor chords - a Cmin9 and a Cmin#13. (note: my theory chops aren't perfect, so i might not be 100% accurate) Experiment with adding Cs, Ds, and A#'s above a C minor chord and see if you can find it.
