This is a somewhat sludgy track I made entirely on the Deluge; quite a few of the sounds are based on samples shared on this forum.
Great work, @hamptonio
It sounds to me like you have run some tracks through a flanger and a phaser, and I'm wondering if you used the Deluge for that, or something external.
There's some great dissonant chords going on there. The bass synth is really dark and the way the notes bleed into each other gives it a dirty, sludgy sound, as you say. Maybe that's what you were going for but to my ears it would benefit from a bit more space in the low end.
