Oberheim's description of the Oberheim TEO-5 polyphonic analog synthesizer



TEO-5 is a modern instrument, crafted with classic analog soul, yet sleek and powerful for today's sonic journeys.


Thomas Elroy Oberheim. TEO. More than his initials, they mark the culmination of a synth pioneer’s vision.  TEO-5 captures the secrets of the OB-X, Four Voice, and TVS, their legendary spirit distilled into an innovative dream machine.



Take your music to the next level with genuine analog VCOs. TEO’s five inspiring voices sing with the warmth and power of pure triangle, sawtooth and pulse waves.

But this isn’t your grandfather’s synth. Updated oscillators roar with analog through-zero FM, birthing textures never heard before in an Oberheim instrument.



The legendary SEM state-variable filter allows you to morph from 2-pole Low-Pass to High-Pass through a phaser-like Notch, and even provides a switchable Band-Pass mode.

Experience the distinctive resonance heard in countless hit songs over the last five decades. A tremendous variety of tones are possible with Oberheim’s signature tone shaping tool.



Beyond providing the classic modulation sources like the OB-8 envelopes, TEO-5 offers poly and mono LFOs with tempo sync, and the full range of performance controls.

With its flexible modulation matrix designalmost any route is possible in TEO-5, including audio rate sources and destinations. Dig into the 19 routes, 19 sources and 64 destinations and let inspiration find you.



TEO-5 is your gateway to new sonic frontiers with modern modulations and vintage warmth. Experiment with through-zero FM shaped by the legendary SEM filter, topped off with iconic Oberheim effects. Compact, affordable, and bursting with creativity, TEO-5 sparks your musical journey, whether you’re a  budding artist or a seasoned pro.



Unleash the dual digital effects, letting chorus, delay, and reverb paint your sonic canvas.

And for a taste of true Oberheim alchemy, dial in emulations of Tom’s legendary Phase Shifter and Ring Modulator, conjuring swirling textures and metallic resonances straight from the golden age of synthesis. 



TEO-5 is a sonic playground. Its 64-step polyphonic sequencer sparks infinite melodic possibilities, while the multimode arpeggiator keeps your rhythms pulsing and pounding.

Or play it live with the premium Fatar keybed, every note awash with responsive joy. From soaring leads to cascading chords and thunderous basses, TEO-5 will elevate every aspect of your musical performance.
