OBERHEIM TEO-5 | 44-key 5-voice Polyphonic Analog Synthesizer

TEO-5

44-key 5-voice Polyphonic Analog Synthesizer

Explore new sonic frontiers with the Oberheim TEO-5, a compact and affordable 5-voice polyphonic analog synthesizer bursting with inspiration. Dive into legendary analog warmth reimagined with modern synthesis features and sculpt your sound with thru-zero FM pulsing though the iconic SEM filter and classic Oberheim FX.

The TEO-5 captures the secrets of the OB-X, Four Voice, and TVS, distilling their signature sound-shaping capabilities into an instrument for everyone. Notable features include two VCOs plus a sub oscillator, a classic state-variable SEM filter, two DADSR envelopes, two LFOs, and a vintage knob that adds voice-to-voice variations in component behavior. You'll also be impressed with the polyphonic sequencer, arpeggiator, and built-in effects including a dedicated reverb, overdrive, and a digital multi-FX engine with chorus, delay, flanger, phaser, ring mod, and more. From studio to stage, TEO-5 is your sonic passport—a gateway to the Oberheim legacy and priced to unleash your own.
