Oberheim TEO-5

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.

Key Features

• Five true analog voices: Pure triangle, sawtooth, and pulse waves with added sub-oscillator and noise for rich sound design
• Through-zero FM (X-Mod): Analog oscillator modulation that opens creative timbral possibilities never heard on earlier Oberheim instruments
• SEM-inspired state-variable filter: Morph between low-pass, notch, and high-pass continuously, with a switchable band-pass mode for classic Oberheim character
• Comprehensive modulation matrix: 19 sources, 19 destinations, and 64 mod slots—allowing complex routing including audio-rate modulation
• Classic OB-8 envelopes: Two ADSR envelopes and poly/mono LFOs, all fully tempo-syncable for dynamic sound control
• 64-step polyphonic sequencer & arpeggiator: Create evolving patterns or rhythmic textures with integrated tools and a premium Fatar keybed
• Dual digital effects: Chorus, delay, reverb plus Oberheim-style phase shifter and ring modulator expand its sonic footprint
• OLED display & deep editing: Clear visual feedback for parameters, plus an editor software for advanced patch management
• 256+256 program memory: 256 factory sounds and 256 user slots accessible via intuitive patch navigation
• USB & MIDI I/O: Class-compliant USB MIDI and traditional DIN MIDI for seamless integration into any setup
