Oberheim 2 Voice: The Classic Analog Synthesizer

Overview of the Oberheim 2 Voice

The Oberheim 2 Voice, introduced in 1975, is a classic analog synthesizer known for its rich, warm sound and versatile capabilities. It was one of the first polyphonic synthesizers available, allowing musicians to play two notes simultaneously, which was groundbreaking at the time.

Key Features of the Oberheim 2 Voice

• Synthesis: Analog subtractive synthesis
• Oscillators: 2 SEM (Synthesizer Expander Module) units, each with 2 VCOs
• Filter: 2-pole multimode filter (low-pass, high-pass, band-pass, and notch)
• Envelope Generators: 2 ADS envelope generators per SEM
• LFO: 1 LFO per SEM with multiple waveforms
• Keyboard: 37-note keyboard
• Polyphony: 2-voice polyphony
• Sequencer: Built-in analog sequencer with 8 steps per voice
• Modulation: Extensive modulation options including cross-modulation between SEMs
• Connectivity: CV/Gate inputs and outputs

Development and Innovation

The Oberheim 2 Voice was developed by Tom Oberheim, a pioneer in the field of analog synthesis. It was designed to offer the flexibility of modular systems in a more compact and accessible format. The inclusion of the SEMs allowed for a wide range of sound-shaping possibilities, making it a favorite among musicians and sound designers.
