A thing of analog beauty
Originally meant as a companion module to sequencers and other synths, the SEM sported a multi-mode filter and two tremendous oscillators that made it unlike anything else. Combining multiple SEMs into 2, 4, and 8-voice systems took things to another level - just ask Rush or Herbie Hancock. SEM V puts all this power, and more, right in your DAW.
True Analog Emulation® technology brings all the fat and warmth in a way no sampled version can. You’ll hear the difference and so will your audience.
From synthpop to hip-hop, almost every musical style can use some of the burbling bombast of the SEM.

Set polyphony up to 32 voices for massive brass, swelling strings, and ponderous pads.
The 12dB/octave multimode filter that sounded unlike anything else, eventually shaping the identity of Oberheim®, exquisitely recreated.
The monophonic synth that
launched a polyphonic revolution
Tom Oberheim had already enjoyed success building effects and a sequencer — and as the Los Angeles dealer for ARP synthesizers. He first conceived the SEM as an add-on, but it became a centerpiece.
Tom’s purpose was twofold: A sonic expander for synths like the 2600 and the Mini, and a stand-alone synth module for pairing with his DS-2A sequencer. Of course, you could also add SEMs to each other. Tom Oberheim himself said, “The SEMs were the beginning of synths being able to do polyphonic orchestration.”Discover the history of Sem
A driving force behind the SEM was that the DS-2A took over the connected synth, which was often modular and always expensive, so players didn’t want to give up control while the sequence ran. An affordable and compact synth-in-a-box dedicated to the sequencer was the perfect solution.
Oberheim released the SEM in 1974. The Two-Voice and Four-Voice synths — two or four SEMs and a keyboard — followed a year later. The latter included a Programmer that could save and recall settings for all the SEMs at once, unifying them as a single instrument. This was three years before the Prophet-5 would claim the title of first fully programmable polyphonic synth. That’s true if you consider the Prophet’s all-in-one “slab” form factor. Multi-SEM synths were more like mini-modulars that folded up into their own carrying case, but they made Oberheim first to market with polyphony and basic programmability.
SEM-based synths maxed out with the Eight-Voice. It was a favorite of Herbie Hancock, Joe Zawinul of jazz-fusion giants Weather Report, and Geddy Lee of Rush, who famously melded his Eight-Voice with a Mini in a dual-keyboard custom build.
The SEM circuit formed the basis of the OB-X (1979), which was available in four-, six-, and eight-voice configurations. Successors like the OB-Xa (1981) and OB-8 (1983) used the same circuit design on microchips. SEM V can function like a single SEM, an Eight-Voice, or anything in between.
An SEM for Today
We faithfully modeled the core controls of the SEM, then added a few tricks of our own to make it more SEM than ever.
Its sound ranges from creamy to downright bossy, serving up leads, basses, pads, brass, strings, and special FX with gusto. Our additions give it a big boost while staying entirely within the spirit of the original.
01. Multi-Mode Filter
The SEM’s calling card was its 12dB-per-octave filter, which was continuously variable between lowpass, bandpass, and highpass.
02. Bring the Boom
A sub-oscillator one or two octaves below the two VCOs allows for sounds with floor-shaking low end.
03. Extra LFO
The SEM had a single LFO. SEM V adds another and lets you modulate VCO frequency or pulse width from either. Of course, both LFOs sync to tempo.
04. Classic Arpeggiator
Generate retro riffs with the tempo-syncable Arpeggiator, which features a Random mode, Hold, and up to a four-octave range.
05. Here’s the Mixer
Mix the volume of sawtooth or pulse waves, as well as the sub-oscillator or white noise, heading into the Filter section.
06. Built-in Effects
Quickly dial in the perfect amounts of Overdrive, Chorus, and Delay to put the final sheen on your SEM V sound.
Open up SEM V’s Advanced Panel to access a treasure trove of creative sound design features.
The magic of software is that once we’ve gotten the original sound exactly right, we can add functionality that would be a lot more costly in hardware. The SEM is already a powerhouse, but these extras make it a powerhouse with a Ph.D.
The Programmer controls six parameters for up to eight virtual SEMs as you play notes. It’s like having a more sophisticated Oberheim Eight-Voice.
We’ve greatly enhanced the SEM’s modulation capability with eight independent routings. Go nuts with eight sources and 26 destinations!
Six settings of your choosing can change based on the note played according to a user-definable curve. It’s the most surgical keyboard tracking on any synth.
Tweak and tempo-sync the built-in FX here, then dial in each. The Delay even features a stereo ping-pong mode.
From Brit prog to American pop to Berlin acid, these original compositions from some of our most talented users show just a few of the places SEM V can take your musical ideas.
Dead Can DanceThe SEM V has a simplicity and elegance that was a feature of many 70’s synths. The 8 Voice programmer module in particular is a joy to use especially in combination with the arpeggiator, delivering beautifully evolving sequences and pulsating arps.
Producer - ComposerArturia has once again delivered a faithful recreation of another analog classic with SEM V. SEM V is a highly musical instrument that evokes the original in so many surprising ways.
Producer - ComposerAnalogue warmth & movement abound in the unique multimode filter found on the SEM and I'm happy to say that this has been faithfully recreated.
Producer - Composer (Alt-J / Oscillator Hell)An absolute classic that I am extremely glad has been virtualised and a true asset to anyones sonic arsenal.
Producer - ComposerArturia has done it again! I am proud to be a part of the beta testing for the SEM V... the original SEM was one of my first and favorite synths. Arturia has nailed it ...plus polyphony without the tuning nightmare. What more can you ask for?
Mixing Engineer / ProducerThe Oberheim SEM is my favourite synthesizer in my studio - with the Arturia version I always have it with me.
Spoon / Hamilton LeithauserI’m digging the arpeggiating possibilities of the SEM V.
Sound On Sound
On SEM V
“[The SEM V] will be an excellent complement to other synths and soft synths - beautifully simple to use in the first instance, while offering greater depth when you're ready to take advantage of it. Oh yes, and then there's that sound !”
On SEM V
“An awesome synth which takes the Oberheim® classic and expand it into a versatile all-rounder”
On SEM V
“As a straight emulation of the classic SEM sound, the SEM V ticks all the boxes, but the software has so much more to offer when you explore it in greater depth : small but effective additions to the SEM design, advanced voice editing features and, of course, an excellent polyphonic mode. The range of sounds available is much greater than the SEM name might suggest, covering classic Oberheim® ground and much more, and this makes the SEM V a great synth in its own right.”
On SEM V
“I'm impressed by how well SEM V captures the sound of Oberheim® hardware, and its extended features make it more flexible than its namesake [...] SEM V is one of the most genuinely analog-sounding soft synths yet. If you love the sound of vintage synths, SEM V should be a part of your virtual rig.”
On SEM V
“The SEM V is a gorgeous-sounding synth and, crucially, like the original it’s fairly easy to get to grips with. You don’t have to be a synth wizard to tweak and design sounds, and it’s a lot of fun when you play around […] The new features – arpegiattor, sub-oscillator and three modules - extend the functionality of the instrument even further, and will surely help you get more out of what is already an excellent synth.”
