sound in "smack my bitch up" by "the prodigy&
 

Hi!

Does anybody know how to make the synth sound in "smack my bitch up" by "the prodigy"? I am talking about this nasty sound going up and down, which plays several notes throughout the song. It sounds very cool when the girl sings the oriental melody, and the synth plays notes in the background. It sounds like a short filter sweep with resonance and heavy chorus or detuning. It could also be synced osc's with fm-modulation. Well, I have some ideas, but I don't get near the sound that I hear and that I want. My imitations don't have that "nasty" sound. I guess the right chorus parameters play a vital role, especially the feedback of the chorus. Has anyone made a similar sound or knows how to do it?

Thanks very much,

Thorsten
