A DUOPHONIC LEGEND, REBORN WITH MODERN POWER.
In 1975, Tom Oberheim revolutionised synthesiser design with the original TVS – Two Voice Synthesizer. By combining two SEMs 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 including Martin Gore, Adrian Utley, Peter Baumann, Lorn, The Prodigy, and Nils Frahm.
Decades later, the TVS 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 the GForce 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-time Oberheim 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.
MORE THAN THE SUM OF ITS PARTS
At the heart of the TVS Pro are two fully modelled SEMs, 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 faithful SEM 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 over 400 converted patches from the GForce SEM, alongside 220+ brand-new sounds—giving you immediate access to a world of characterful tones.
SEQUENCER-DRIVEN CREATIVITY
At the heart of the TVS Pro is its intuitive dual 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 & 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.
