i love it man...don't think it needs any synths....its a nice percussive deep techno and the sfx keep it going along great i think. It sounded like a few timing issues also, but if that being deliberate its good to produce outside the box.
nice tight mastering...also enjoyed the way the song evolves by the end of the production.....great for when djs want to go into something more funky perhaps...nice track!
