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

The Oberheim Legacy is Yours

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.

Step Up to TEO-5

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. 

Ghostly images of the vintage Oberheim Phasor and Ring Mod effects float above TEO-5.

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.

Voice Control

Here you can set Portamento (glide) rate and turn on Unison voice stacking. The Vintage knob affects the voice-to-voice variability of TEO-5’s envelopes, oscillators, and filters to replicate the behavior of vintage instruments with all of their organic instabilities.

LFO Panel

TEO-5 features two LFOs, one mono and one poly, each with five possible wave shapes: triangle, sawtooth, reverse sawtooth, square, and random (sample and hold). Both can be synchronized to tempo and are freely assignable via the modulation matrix.

TEO-5 logo


Select the waveforms that generate the raw sound of the TEO-5. Each of the two oscillators produce sawtooth, pulse, or triangle waves. Combine waves for extra punch. Kick in hard sync and X-Mod (through-zero frequency modulation) for more edge and sonic possibilities.

TEO-5 logo


This is the soul of the TEO-5 sound. The classic SEM-lineage, two-pole, discrete resonant filter design is here, with its unmistakably distinctive sound. Morph from low-pass to high-pass through notch, and switch into band-pass mode whenever you like, exponentially expanding your sonic possibilities.

The 5-stage (delay, attack, decay, sustain, release) filter and volume envelopes give shape to the harmonics and loudness of TEO-5’s sounds. Modeled after the OB-8 envelopes, use them to ease into a silky pad, or thump your chest with a punchy bass.

Use the arpeggiator to create chord-based rhythmic patterns. Hold down several notes and the arpeggiator will cycle through them at the rate that you set and a pattern that you choose: up, down, up & down, or note order played. You can even set a transpose range for the arpeggio up or down by 2 octaves.
