Custom Oberheim FVS - "Son of 4 Voice" System

Note: Auction links are affiliate links for which the site may be compensated.

via this auction

"The ensemble is made of 4x vintage Oberheim SEM modules, revised and calibrated, a good psu, plus a 4 voices mixer inspired by FVS mixer, a Vermona 4 channels midi interface, packed in a tailored-fitted, pro-built flighcase. One of the SEM has cheese-like cheeks (a lots of mods where installed on this one) but it is back to original specs now. New face panels exists as well.

While it was built to stay true to the original Four Voice by Tom Oberheim - it is also quite easy to add a ton of patch points and convert this to a modular dream-machine"

"This black Tom Oberheim TVS-Pro -- or Two Voice Pro-- is in immaculate condition with no issues whatsoever.
Both SEM's tune perfectly and hold well through hours of use. As you can see, the patch panel really expands the capabilities allowing you to route velocity to different places for example.

Tom Oberheim himself said these were made from the exact same schematics and electronic parts values from the originals. While I haven't tried this myself, apparently an original SEM from the 70's can work if you swap them out.
I have used it mostly in "dual mono" mode for the world's best stereo mono synth lines. Duplicating the settings on both SEM's make this a huge stereo sound since each SEM is analog and slightly different. It is in my top 5 synths of all time.

There are less than 100 of these in existence and perhaps the best version of a Two Voice.
This one has been used in my non-smoking studio professionally since 2016, with no issues whatsoever.
It has the final firmware updates: Keyboard v24a and Seq v30 from 2018
It will come with original manual, and power cable."

"This Tom Oberheim TVS-Pro -- or Two Voice Pro-- is in immaculate condition with no issues whatsoever.

"Regardless of being the vintage 70s original issue or this Tom Oberheim remake the sound truly speaks for itself – and the SEM filter would in my personal desert island test beat the Minimoog Ladder by a hair. This is the rarest of all TVS's and only around 100 was made. Unofficial sources say that the actual number is closer to 50. Theses come on sale (if they ever does) once or twice a year so here's the rare chance to get your hands on one. The synth is in absolutely mint condition and has no flaws to find anyway."

"Tom Oberheim SEM patch panel. THIS is the version for full integration into modular systems: extensive patchbay allows CV/gate control as well as output of a wide array of the SEM's controls. No MIDI! Features additional patch points not available in the SEM pro version.

Earlier version with better quality knobs: later models with the Marion Corp logo ("M") on top don't have the classic Oberheim dials anymore.

Technically fully functional. Very good cosmetic condition. Some marks and light scratches, particularly on edges and back & front panels.

Comes with original box & switchable PSU 110-240V, EU plug."

"This early unit, #584, has only been used, sparingly, in my studio. The sound is amazing and the filter is super useful on other inputs as well. I just tested everything before packing up and the unit is in great shape, no issues found. This model has the patch panel as well as CV & Gate outs in back...MIDI too. I was using the CV & Gate outs to control my 777 and the audio input for the filter. Nice!

Tom serviced this back sometime between 2010-2012ish when the input level knob went. Been rock solid since."

"Legendary synth designer Tom Oberheim created a current rendition of his classic SEM (Synthesizer Expander Module). The SEM, Tom’s first synthesizer, was well loved for its beautiful sound and just the right combination of synthesis modules and patching in a compact, portable package. In fact it was so revered that people requested Tom make the SEM again, so he did. Consisting of a 100% analog signal path through two oscillators, two envelope generators, and filters, the SEM is an exceptionally massive sound design module. This Oberheim Two Voice Pro features two of Tom's renowned SEM's, along with a 3-octave, velocity sensitive keyboard, a mini sequencer with 16 steps, and up to 56 mini-jack patch points for each module."
