Oberheim TEO-5 – 5-Voice Analog Polyphonic Synthesizer
The TEO-5 is Oberheim’s bold return to analog polyphony—rooted in the legacy of the OB-X, Four Voice, and TVS, yet reimagined for the modern synth world. It blends warm VCOs, the iconic SEM filter, and exciting new features like through-zero FM and a deep modulation matrix to give both vintage tone and contemporary flexibility.
