Oberheim TEO-5

Oberheim TEO-5 is a compact 5-voice polyphonic synthesizer that blends iconic analog warmth with modern versatility, featuring two analog VCOs with multiple waveforms, SEM-style VCF, a powerful modulation matrix, onboard effects, a 64-step sequencer, and a premium Fatar keybed with velocity and aftertouch.

The TEO-5 offers two fully analog VCOs with selectable waveforms including saw, square/pulse, triangle, and noise. Oscillator features like hard sync, X-Mod, and zero-crossing FM deliver a wide sonic palette, while a sub-oscillator and enhanced unison mode allow stacking up to five voices. The SEM-based variable-state filter smoothly morphs between lowpass, notch, and highpass modes, recreating the legendary Oberheim character with rich resonance and distinctive tone shaping.

Modulation is exceptionally flexible, with a matrix offering 19 sources, 19 targets, and 64 destinations. Both polyphonic and monophonic tempo-synced LFOs are available alongside OB-8-style envelopes. Digital effects include dual FX processors with reverb, stereo delay, chorus, flanger, ring mod, phaser, tape delay, and more. A powerful arpeggiator and a 64-step polyphonic sequencer expand performance capabilities.

The TEO-5 features a 3.5-octave Fatar keyboard with channel aftertouch, high-resolution OLED display, and real-time control via 5-pin MIDI, USB MIDI, CV I/O, and pedal inputs. With 256 factory programs and 256 user slots, a vintage control knob to add voice-to-voice analog character variation, and seamless studio or live integration, TEO-5 brings Oberheim’s legendary sound into a modern compact form.
