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 toohttp://www.elektropolis.de/synthanorma.pdf
The 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.
