Oberheim is a legendary name in the world of synthesizers, known for creating some of the most iconic analog synthesizers of the late 20th century. Models like the OB-X, OB-Xa, and OB-8 have left an indelible mark on the music industry. Now, Oberheim returns with the OB-X8, a synthesizer that combines the best elements of its predecessors with modern enhancements, promising to deliver the ultimate analog experience.
Sound Engine:
The OB-X8 is powered by a true analog sound engine that employs subtractive synthesis. This classic method is renowned for its warmth and depth, making the OB-X8 capable of producing rich, vintage tones. The sound engine’s quality and versatility are top-notch, allowing for a wide range of sonic possibilities from lush pads to punchy basses.
Oscillators and Waveforms:
Featuring dual oscillators per voice, the OB-X8 offers a variety of waveforms, including sawtooth, square, and pulse waves. These oscillators can be detuned and synchronized for complex sounds. While the OB-X8 doesn’t support wavetable synthesis, its analog waveforms are robust and can be further shaped through various modulation options.
Filters and Modulation:
The OB-X8 includes a classic Oberheim filter section with 2-pole and 4-pole options, providing low-pass filtering. The modulation capabilities are extensive, with multiple envelope generators and LFOs that can be routed to various parameters, allowing for intricate sound sculpting. This depth of modulation makes it ideal for creating evolving textures and dynamic sounds.
Effects Processing:
Unlike many modern synthesizers, the OB-X8 stays true to its analog roots and does not feature built-in digital effects. This choice ensures that the pure analog signal path remains uncolored, allowing users to use their preferred external effects for processing.
Polyphony and Voice Modes:
The OB-X8 offers eight voices of polyphony, making it suitable for complex chordal playing and layering. It supports various voice modes, including monophonic, polyphonic, and unison, but does not offer multitimbral capabilities. However, its eight-voice polyphony is sufficient for most performance and studio needs.
Keyboard and Controls:
Equipped with a 61-key keyboard, the OB-X8 includes velocity sensitivity and aftertouch, enhancing expressiveness. The control interface is well-designed with a logical layout, making it user-friendly for both live performance and studio work. The knobs and switches are sturdy and provide a tactile, responsive feel.
Sequencing and Arpeggiation:
While the the OB-X8 does not have a dedicated step sequencer for programming melodic patterns, it has a very capable arpeggiator with several modes and options. It syncs via an internal clock and is the primary tool for rhythmic/melodic pattern creation.
Build Quality and Durability:
The OB-X8 boasts exceptional build quality, constructed with premium materials and a robust chassis. Its durability ensures it can withstand the rigors of live performance and intensive studio use, making it a reliable instrument for professionals.
Connectivity and Power Base:

The OB-X8 offers comprehensive connectivity options, including MIDI, USB, and CV/Gate, facilitating integration with modern setups and vintage gear alike. Audio outputs are high-quality, ensuring a pristine signal path for recording and live sound.
Price and Value:
The OB-X8 is positioned as a high-end analog synthesizer, with a price tag that reflects its premium build and sound quality. While it is an investment, the OB-X8 offers excellent value for those seeking authentic analog sound and superior craftsmanship.
Pros:
