A wiki would be a great resource. A trawl through the interwebs shows how many people do ask a similar question on achieving so called ''Berlin School of Electronic'' style sequences. I guess a very simple four step one would be: F/G#/A# and then a skip. At around 106 BPM. You can hear this as the first pattern on the Ricochet album... or the Live at Coventry Cathedral DVD. I am not sure if the notes are exact - but, it is close and forms a good base to add other patterns too.
