My memory of this track is really vague - aint the sound you're talking about pretty much a bog standard hoover patch with an HP filter on it being messed with?
If so, find a patch with hoover or something inthe name (there must be on in there somewhere - all synths have a hoover patch these days
) and tweak it to death
Or am I thinking of another track - maybe I'm just suffering from beer deficiency syndrome..?
