Yo, I've been thinking about this quite a bit, and listening to your tracks (still not bought it sorry). I think I was looking at it in the wrong way, in that you're probably getting the exact right sound for the music. I'm not really familiar with the genre, so I was looking at it from a different perspective.
Anyway, I was in the studio yesterday working on some of my stuff, and at the end of the session I thought i'd try some synth bass sounds for fun. I played it to a click and then put some drums over the top. There's a lot of dodgy playing and the sound isn't great - i'm miles away from the cool synth sounds you have, but I like the "dirtiness".

EDIT: It's not uploading - what's the deal with that?
EDIT: OK, something's up with the software I suppose. I've put it here "http://creepjoint.co.uk/drumnbassthing.mp3" [media]http://creepjoint.co.uk/drumnbassthing.mp3[/media]
