Dirt
You are taking the criticism here and making it far too regimented, losing sight of what, I believe, first flowed from you upon making these 'Dark Beat' loops.
I have listened to them all, and this one is the winner.
You do not need additional lines, that would only serve to conflict with the filthy nature of this groove. You can't have a monotonous saw bass and haunting, middle-tweaked, filtered keys and then try and break up the beauty of it's simplicity.
Christ, listen to Flat Beat.
You were on to something. Don't become detached from it to turn it into something less personable.
