In 1975, Tom Oberheim revolutionised synthesiser design with the original TVS – Two Voice Synthesizer. By combining twoSEMs and a keyboard, he introduced true duophony to the world—enabling musicians to play two independent voices simultaneously and explore harmonically rich, evolving soundscapes. It was a bold step forward, embraced by visionaries includingMartin Gore,Adrian Utley,Peter Baumann,Lorn,The Prodigy, andNils Frahm.

Decades later, theTVS Pro modernised that vision, adding a built-in sequencer, extended modulation, and refined controls—all while staying true to its unmistakable sonic DNA.

Now, with theGForce Oberheim TVS Pro plugin, this landmark instrument enters a new era. Developed in collaboration with Oberheim, this recreation captures not only the depth, warmth and character of the original, but also the spirit of innovation that made it extraordinary.

Whether you’re a long-timeOberheim fan or new to SEM-based synthesis,TVS Pro is a tool you’ll return to again and again—for its tone, flexibility, and sheer playability.

AN UNMISTAKABLE SOUND THAT’S MORE THAN THE SUM OF ITS PARTS

At the heart of theTVS Pro are two fully modelledSEMs, each offering:

• Two VCOs with pulse and sawtooth waveforms

• The legendary Multi-Mode Filter

• Two ADS envelope generators

• One LFO

Every component has been carefully emulated to preserve the character and nuance of the original instrument—right down to the subtle analogue inconsistencies that gave it life. The result is the most faithfulSEM emulation available, wrapped in a duophonic architecture that allows for complex, organic interactions between voices.We've also added a 3rd VCO which can be an LFO too, velocity and aftertouch which weren't on the hardware, per SEM.

We’ve even included over400 converted patchesfrom the GForce SEM, alongside220+ brand-new sounds—giving you immediate access to a world of characterful tones.

SEQUENCER-DRIVEN CREATIVITY, MADE FOR TODAY’S WORKFLOW

At the heart of theTVS Pro is itsintuitivedual 16-step sequencer, designed not just for precision, but for play. With rapid workflow, fluid modulation, and hands-on control,TVS Pro becomes a true sequencing playground—a space where musical ideas evolve effortlessly and experimentation is rewarded.

Whether crafting intricate patterns or building evolving textures,TVS Pro gives you the tools to explore freely. And with the addition of phaser, analogue-style stereo delay and lush reverb, you have everything you need to bring depth and polish to your performances, straight out of the box.

A COLLABORATION GROUNDED IN LEGACY AND VISION

Our partnership with Oberheim began with the award-winning OB-E v2, and it continues to shape how we approach vintage re-creations. Working with Oberheim  on the TVS Pro plugin, and sharing a passion for authenticity, has helped us create something that feels true to the original
