This request comes up a fair bit and I thought there was a sticky elsewhere due to that. Still, once more with feeling, Al...
As my esteemed colleague said, BM is a triumph of the technology of the time: Steve programming the DMX with all of them contributing to the pushes (the drum programme is a real four-way collaboration!), the Moog Source background bass, the Prophet 5 bits and the Emulator samples: c'est magnifique! Confusion was basically a celebration of the Roland TR808 and the Pro-One and the DMX reappeared on Thieves Like Us and This Time Of Night. The DMX had a volatile memory: a roadie tripped over the power cable before a gig, it wiped five songs they were due to play and they were forced to drop them from the set!
The synths in Joy Division were mainly the Powertran Transcendent 2000 which Barney built from a kit, a Sequential Circuits Pro-One (which is the same one which later turned up on Confusion and was sold on Ebay a while back) and an ARP Quartet which was later replaced by a Quadra. All of this lot was used on Closer, Movement, Everything's Gone Green and Temptation...and was later nicked in New York (except the Pro-One which I think was being fixed). They also used a EMS vocoder which appeared on The Beach and Ecstacy but frequently broke down and eventually stopped working, despite having a fortune spent on it.
Their most reliable synth was the infamous Octave Plateau Voyetra, the one you can see Gillian playing in The Perfect Kiss video (mmmm...lovely blusher). They then went Yamaha mad and bought DX816s (eight DX7s in a rack) which is all over Low-Life which was sequenced by a hideous QX1 sequencer.
I think Technique signalled a move to Mac-based sequencing etc and they've been able to slim down their live kit since then, using Roland A50 master keyboards and XP50 workstations . Check the new live DVD to compare what they used years ago and what they used at the cessation of live action in 2006?
Hope this helps a bit. Good luck!
