The OB-X8 is the triumphant return of a legendary synthesizer. As Oberheim's most faithful recreation of the classic OB series, it carries the full DNA of the originals, from the warm, punchy oscillators to the silky filter sweeps that made the OB-X a studio staple. This is eight voices of pure analog polyphony, rebuilt by the engineers who knew the originals best, and designed to be the finest modern OB ever made.
Pure Analog Tone, No Apologies
The OB-X8 isn't an analog simulation — it's the real deal. The engineers obsessively analyzed how every circuit in the original OB series interacted, allowing them to recreate the nuances, quirks, and character that made those instruments legendary. The result is a synth that sounds undeniably like an Oberheim, because it fundamentally is one.
8-Voice Pure Analog Polyphony: Two discrete SEM/OB-X-lineage VCOs per voice deliver the punchy, harmonically rich tone the OB series is famous for — fat, present, and impossible to ignore in a mix.
Dual Filter Lineage: Discrete SEM-lineage VCFs deliver authentic OB-X-style tone, while genuine Curtis filters bring the bold character of the OB-Xa and OB-8. One synth, two legendary filter flavors.
Vintage Knobs: Dial in the perfect amount of organic imperfection. This control introduces voice-to-voice instability, because sometimes the most musical thing a synth can do is misbehave a little.
Real Walnut End Cheeks & Premium Build: The OB-X8 features real walnut end cheeks and a premium build that feels every bit as good as it looks.
Expressiveness That Actually Means Something
Great analog tone is only half the equation. The OB-X8 is built to respond to how you play — not just what you play. With a 61-key FATAR keyboard that's sensitive to both velocity and aftertouch, every note feels alive. Whether you're laying down slow, evolving pads or hammering out staccato leads, the OB-X8 tracks every nuance of your performance with surgical precision (and a little soul).
Velocity & Channel Aftertouch: Real-time expressive modulation that ties your dynamics directly to volume and filter response, giving even simple chord stabs a sense of life and movement.
Enhanced Unison with Variable Voice Stacking: Stack anywhere from one to all eight voices in unison for a wall of sound thick enough to furnish a room with.
Classic Oberheim Pitch and Mod Levers: Iconic and ergonomic, these allow expressive note bending, vibrato, and arpeggiator control right at your fingertips — no menu diving required.
High-Resolution OLED Display: Patch management and advanced features are just a glance away, without the frustrating deep-menu navigation that makes some modern synths feel more like spreadsheets than instruments.
A Living Archive of OB History
The OB-X8 ships with over 400 factory programs, including the complete original factory sound sets for the OB-X, OB-SX, OB-Xa, and OB-8. That's not just a preset library — it's a time machine. Meticulously modeled envelope responses match each OB model exactly, so when you call up an OB-X patch, it behaves like an OB-X. No guesswork, no approximation.
400+ Factory Programs: The full original factory sound sets from four OB-series classics, plus room for over 600 user-programmable presets of your own creation.
Bi-Timbral Capability: Run two presets simultaneously for splits and layer combinations — bass on the bottom half, leads on top, no extra gear needed.
Additional SEM Filter Modes: High-pass, band-pass, and notch functions expand the tonal palette well beyond the classic OB-X filter, giving you a broader sonic toolkit without straying from the OB aesthetic.
Comprehensive Connectivity: Stereo and mono outputs, MIDI In/Out/Thru, USB, volume, sustain, and filter pedal inputs, plus an arpeggiator clock input that keeps the OB-X8 in conversation with the rest of your studio.
The OB Sound, Perfected
The Oberheim OB-X8 isn’t just an approximation or a digital homage; it’s the most faithful recreation of the classic OB series ever made and a genuine continuation of its lineage. It delivers the same warmth and punch as the originals but with an expressiveness they could never quite achieve. If you've been searching for the iconic OB sound without the maintenance headaches, tuning drift, and sticker shock of the vintage market, the OB-X8 is the synth you've been waiting for.

The OB-X8 is a faithful, from-the-ground-up recreation of the classic OB series, with the same core analog circuitry and sound character as the originals. It adds modern features like velocity sensitivity, aftertouch, and expanded preset storage that the vintage instruments never had.
Yes, the OB-X8 uses pure analog signal paths throughout, including discrete VCOs, SEM-lineage VCFs, and genuine Curtis filters. There's no digital oscillator emulation or analog modeling happening here.
The SEM-lineage filters deliver the classic OB-X tone — smooth, musical, and slightly soft around the edges. The Curtis filters add the bolder, more aggressive character associated with the OB-Xa and OB-8. Both are onboard, giving you a wide range of tonal options.
Yes, the OB-X8 is fully equipped with MIDI In, Out, and Thru, along with USB for computer integration. It also includes volume, sustain, and filter pedal inputs and an arpeggiator clock input.
You bet. Its 61-key FATAR keyboard, complete with velocity and aftertouch, alongside the classic Pitch and Mod levers, bi-timbral capabilities, and sturdy construction, make it a powerhouse on stage.
