Im talking about the wierd warping bass sounds you hear throughout the tune and in alot of modern drum and bass also.
Am i correct in thinking that they come from a 303?

Possible but I'm not that sure, I'll get my 303 out and check it for you tonight !

It's all about filter automation and bass resampling to get those kinda morphing sounds
