the original Obi
I recently picked this 70s Oberheim SEM up on flea bay for cheap because it had dodgy pots and switches, but after receiving it, disassembling it and thoroughly cleaning some grime from the board with alcohol and then cleaning the pots and switches with proper cleaner and then giving them 100 turns and flips each she works like new. This module was Oberheim's 1st synth and it was meant to expand existing performance synths with an extra syncable, independently programmable voice via CV/gate. Mine is the common 2nd version, the 1180 model. The 1180 is the basis of the 2 voice, 4 voice and 8 voice performance synths. The thing has the great Obi filters that are less steep than a Moog or Arp. I have used this a little bit slaved to my Studio Electronics MIDI Moog to create Some Oberheim 2 voice diatonic patches with the SE1's fitler set to Oberheim mode and it sounds great. However, the SEM is a 70s synth and the VCOs suffer from considerable drift so it can sometimes be dodgy when recording long passages depending on the weather. Its lack of stability can thicken parts in unexpected ways, but some days the drift becomes unmusical. My original SEM is also noisey and I find myself running it SEM tracks thru denoising software to remove a lot of the unwanted hiss and the slight hum. It probably neds more extensive servicing.
Its a cool piece to have, but with Dave Smith and Tom Oberheim reissuing Obis now with modern, stable Oscillators this piece is only for afficianados. I would recommend new guys in search of the early Obi sound get a reissue keyboard model, a studio electronics boomstar or one of SE's other Obi flavored options. I am considering servicing and reselling it to buy a reissue or boomstar with money left over. However, it has its vintage charm so we'll see. Its the only synth from this seminal era of synth design I own so I may put up with its flaws just to have some legit vintage quirkiness in the arsenal.

Trent Reznor is confirmed to use the Oberheim SEM-1 Synthesizer Expander Module, as it is listed among the equipment used to record The Fragile in the Fragility Tour program. This information is supported by the source provided by nin.wiki.
The Oberheim SEM is featured in the "Studio Equipment List" on Vince Clarke's website.
Hammer added an Oberheim SEM module to his setup, later replacing it with an Oberheim Expander. He would layer the Minimoog and the Oberheim together to beef up his sound, specifically adding synced oscillators to the blend.
Spectrasonics Studio List The equipment list for the Spectrasonics studio reads like a gear-head's dream. Favourites amongst Eric's sizeable synthesizer collection include the Access Virus, the Prophet VS, his collection of Waldorf synthesizers, and a 1976 Yamaha CS80. "It's my favourite axe to play, because of the awesome polyphonic aftertouch and that sensuous ribbon," explains Eric.
For effects processing Eric is a fan of the Roland SRV330 reverb, an item that "gets missed by most people, mainly because it doesn't say Lexicon on the front panel." For distortion tricks Eric often uses a rare Boss GL100 guitar preamp: "It's basically the history of Boss pedals in one rack space."
Mixing, until recently, was done on some "very odd, custom-made analogue mixers made by a guy named Mo West," reveals Eric. He recently purchased a Roland VM 7000-series mixer, however, taking him one step closer to an all-digital setup.

"SEA WITCH VS THE ALIENS" by Drew Neumann c2010 Droomusic ASCAP
"The story so far--fresh from their easy victory over the brainless Zombies, the Aliens dive into the Pacific Rim of Fire to raid the earth's resources and steal Methane Hydrates. They encounter something deep underwater that can actually fight back, and she is on her own home turf...
This cue features the Euro and Frac system set up in this simple patch--the one on the left is called Morbeus, it is an Emu/Paia homebrew made from Emu SSM evaluation boards and Paia EKX series boards. On the right top to bottom is an Encore Expressionist, Analogue Systems modular, Blacet, and Doepfer A100 modulars. Below that is a Powertran Digital Delay and an Alesis Quadraverb. These synths are backed up by 2 Waldorf Microwave 1, WAVE, and Q+, a Minimoog, 2 Minimoog Voyagers, Studio Electronics Omega 8, 2 Oberheim SEMS, a Tom Oberheim New SEM, Access Virus B and C, Arturia Origin, 2 MacBeth M3X, Jomox Sunsyn, Alesis Andromeda, and the 5U Knob Grotto. Mixed live off of all of the synths, this used 63 tracks and a couple of hundred voices. It probably should be titled the battle against noise floor and ground loops, but I won that battle!"
