Reply to PauL Kalkbrenner

I'm a massive fan of Paul Kalkbrenner, but I still scratch my head at how he manages to make such great synths. In this song @ 1:44 a high pitched synth comes in, can anyone offer some advice on making a similar sounding synth? From what I can guess he is using some sawtooth waves with distortion, delay and maybe some ring modulation (and a hp filter of course). Also if you have never heard his music or seen the film "Berlin Calling" I highly recommend them both.
