A Pioneering Synth Vision — Fulfilled

This article was Written By

Get to know them!

For over 50 years, the instruments and machines painstakingly crafted and innovated by Tom Oberheim and his cohorts have shaped the sonic landscape of music, spanning the chart-topping to the avant-garde. TEO-5 encapsulates Oberheim’s multifaceted legacy, fulfilling a vision for a powerful, flexible synthesizer that packages time-tested tools with cutting-edge, contemporary character into a powerful, portable design. This 5-voice polyphonic synth captures the ethos of renowned Oberheim instruments like the OB-X, Four Voice, and TVS, refined and reimagined for the contemporary musician looking to pair vintage-derived analog character with envelope-pushing modern malleability. Synthesists at Sweetwater are enamored by the scope of TEO-5, from hallmark Oberheim effects and flexible ADSSR envelopes to its multitudes of modulation and scorching thru-zero FM sonics. Outfitted with a polyphonic step-sequencer, multimode arpeggiator, 44-note Fatar keybed, and robust connectivity options, this dual analog-VCO powerhouse is nothing short of an electrifying Oberheim renaissance.

Namesake sound, decades in the making

This synth derives its name from the mind that birthed its multidimensional magic: Thomas Elroy Oberheim. And true to the maestro himself, TEO-5 excels at weaving between time-tested designs and groundbreaking advancements. Envelopes are painstakingly modeled after those found on the OB-8, while the rich state-variable filter draws straight from the iconic SEM, powering unrivaled sonic sculpting via all-analog VCOs and VCFs, deploying oscillators supercharged to rip through the mix with searing thru-zero FM synthesis.

Two oscillators, one limitless palette

At its foundation, two tripartite oscillators drive the distinctive sonics of TEO-5, each of which features three pure waveforms just waiting to be deployed through the synth’s 5-voice polyphony: triangle, sawtooth, and pulse waves. Dedicated sub-oscillators and noise generators expand the hues of TEO-5, honed through the SEM-inspired state-variable filter’s lowpass, highpass, notch, and bandpass options. Morphing and modulating through each filter lets you create dynamic, evolving tones, with options to individually toggle the filter’s use with each oscillator, the sub-oscillator, and the noise generator, augmenting your armature even further.

Vintage magic and contemporary control

Iconic Oberheim effects abound throughout TEO-5, dialed in for a deliverance of dual-digital dynamism that masterfully molds the synth’s armada of analog aesthetics. TEO-5 is outfitted with a dedicated reverb suite and complemented by chorus, delay, and other time-based effects, with detailed feedback-shaping and depth controls to imbue your textures with dimension. To fully tap the latent aural alchemy of TEO-5, meticulously crafted emulations of Oberheim’s lauded Phase Shifter and Ring Modulator are included to evoke blistering resonances, metallic machinations, and kaleidoscopic harmonics.

Malleable modulation and time-bending tone

Across its dual-oscillator architecture, TEO-5 supports multitudes of sound design capabilities, modulation, and timbral shaping. A dyad of multi-waveform LFOs supports dedicated monophonic and polyphonic modulation, while each ADSR envelope supports a flexible array of amp, filter, auxiliary, and gate configurations with toggled velocity parameters to elicit nuanced, expressive performances. Versatile sync, unison, and oscillator cross-modulation options are expanded by onboard PWM and an adjustable Vintage knob to seize global control over the unpredictability of aged analog.

Primed for studio and stage performance

Whether you’re laying down subterranean basses in the studio or tearing up a solo on the stage, TEO-5’s 44-note Fatar keybed is the site of electrifying performances, capturing each flourish with style. For multilayered madness, a 64-step polyphonic sequencer is your key to limitless ideation and melodic excavation, while the multimode arpeggiator offers a soaring 3-octave range and a trio of repeat functions. When two hands, a pitch wheel, and a mod wheel aren’t enough to harness TEO-5’s suite of expressive and modulation capabilities, its multifaceted array of connectivity supports countless live and recording configurations. A triad of 5-pin MIDI in, out, and thru ports is complemented by a MIDI-capable USB-B port, footswitch input, and pedal input, seamlessly integrating with DAWs and beyond.

What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!
