THE OBERHEIM SEM – A SIMPLE MONOPHONIC SYNTH WITH A HUGE SOUND
When Tom Oberheim created the first Oberheim® Synthesizer Expander Module (model SEM-1) in 1974, he had one goal – to make a synth that sounded great, whilst being extremely simple to use. In the decades since the release of this iconic synth, it’s been used by countless legendary musicians, making the SEM one of the most revered synthesizers of all time.
As well as painstakingly recreating the huge, unmistakable sound of the SEM, the GForce Oberheim SEM also recreates the ethos of the original – a simple monophonic synth that allows you to shape incredible sounds in an instant. And with Tom Oberheim’s seal of approval, you can be confident in its authenticity. Add to this more than 400+ categorised patches, and inspiration is just moments away.
MADE IN COLLABORATION WITH OBERHEIM
We first worked with Tom Oberheim and Marcus Ryle (an inspirational Oberheim engineer during the 80s) when creating the GForce Oberheim OB-E® v2. During this time, Tom and Marcus revealed that they felt there were no software emulations of the SEM that accurately recreated the sound and the ethos of the original monophonic SEM. We decided to change that, and under the close guidance of Tom and Marcus, we’ve developed the GForce Oberheim SEM to ensure an experience that is truly authentic to the original instrument.
Augmented SEM - Extended Mode
The SEM Front can be displayed in parallel the SEM Rear that augments the original SEM.
The MODULE - FRONT
The original SEM, 2 Oscillators, a Multimode Filter, 2 Envelopes and modulation controls. Direct access to FX levels and the Arpeggiator
The MODULE - REAR
The SEM rear panel has additional features including an extra VCO/LFO and extensive velocity and aftertouch control.
THE AUTHENTIC SEM SOUND
Centered around two VCOs with Pulse and Sawtooth waveforms, two ADS Envelope Generators, one LFO, and a magical, legendary Multi-Mode Filter, the SEM sound is more than the sum of its parts. In the GForce Oberheim SEM, every section of the synth has been painstakingly emulated to ensure sonic authenticity. We’ve even modelled the authentic analog inaccuracies of the original SEM, blurring the lines between analog character and digital precision. All this makes the GForce Oberheim SEM the most authentic emulation of the SEM sound available.
Over 400 categorised factory patches.
Arpeggiator and Sequencer
Quick and straight forward arpeggiator and step sequencer.

The stereo delay can set your SEM in movement.
Lush Reverb & FX Lock
The lush reverb can make any sound shine. Lock the FX parameter so that they remain the same when changing patches.
The Arpeggiator is lovely and the FX and Filter are sublime.
I love the simplicity of it. So so simple.
Was hoping to do a Bass Synth and was gonna go Minimoog… not sure now… The SEM has a punch to it.
SIMPLE NEVER SOUNDED SO GOOD
The beauty of the SEM truly lies in its simplicity. With a refined design and feature set, you can easily create warm basses, soaring leads and sweeping arps in an instant. This allows you to spend less time shaping your sounds, and more time making music.
ENHANCED WHERE IT MATTERS
While staying true to the original SEM, we also added a number of enhancements to make the GForce Oberheim SEM even more useful for modern music production. Alongside a new VCO3, which doubles as an LFO with audio rate for additional modulation and FM possibilities, the SEM now has tempo-syncable LFOs with multiple wave shapes, and a host of performance controls via velocity and aftertouch. We’ve also integrated a fun, fast arpeggiator & sequencer, and added a stereo delay and a beautifully lush reverb to sonically compliment your sounds.
Finally, we’ve included 400+ factory patches designed by top sound designers, each created to demonstrate the incredible sonic character of the SEM. Every patch has been categorised and is quickly accessible from the patch browser (arrow navigation friendly). The SEM even integrates with the GForce Oberheim OB-E, allowing users to load their SEM presets in either device. This enables you to quickly sketch out your sounds in the SEM, and then make them polyphonic in an instant.
