Hey - Kraftwerk first used sequencers on Trans Europe Express in 1976. Before the recording of TEE, they commissioned Matten & Wiechers to build them two customized 16x3 sequencers and called it Synthanorma. They used this on the Computer World album too
http://www.elektropolis.de/synthanorma.pdfThe Origin's sequencers are based on the same idea but are far more powerful.
Many of the bass sounds on Man Machine (like on Robots, Spacelab, Metropolis intro, etc), use a layering of two synths, one used for an initial very short/snappy filter "chirp", the second for the main body of the sound. At least that's what it is to my ears. This is also how I programmed the percussion sound at the beginning of the song Man Machine.
I have a Robots patch for Origin in the works. Right now it is in the "fermentation" stage.
