Huge brasses, strings, and pads made the OB-Xa dominate the hottest artists’ keyboard stands, from Prince to Van Halen’s iconic ‘Jump’.
With OP-Xa V, that same unmistakable presence comes to life right in your DAW. There’s just something about the sound that invites you to dig in with both hands and come up with great parts. True Analog Emulation® ensures an authentic muscle car synthesizer experience - while our added touches add heaps of production horsepower that’ll get your creativity racing.
Chart-topping Spirit
Today’s hottest hits are drawing on ’80s synth sounds more than ever. With OB-Xa in your arsenal, you’ll be ready to produce the next one.
The Real Deal
We went back to the source to model the OB-Xa, analyzing every detail, component, and behavior of the genuine article with TAE® emulation.
Jump Right In
The straightforward user interface and signal path can turn a novice into a seasoned synth enthusiast in record time.
Sound That Slaps
TAE® does not emulate sounds - it duplicates how vintage analog circuits behave, and you’ll hear the difference. Earth-shaking, hair-raising, soul-stirring.
Where Hardware Can’t Go
Trouble-free tempo sync. Gorgeous built-in effects. Even more polyphony. The awe-inspiring nature of a classic synth, the enhancements of software.
The Poly
that Could
Oberheim® already had a legacy of fat-sounding synths. But for many, the OB-Xa was the one that hit the sweet spot.
The OB-Xa packed up to eight massive-sounding synthesizer voices in an integrated, programmable slab form factor. After its debut in December 1980, musicians noticed.
Founded by Tom Oberheim, Oberheim Electronics’ first product was a ring modulator pedal introduced in 1970. Then came the Maestro phaser, then the DS-2A, an early digital sequencer that could record and play back notes from popular analog synths in real time — a mind-blowing feat for 1973. Its success led Oberheim to design his own synthesizer: the Synthesizer Expander Module.
Discover the history
Sporting two VCOs, a filter, an LFO, and two envelopes, the SEM was an entire synth voice in a box. SEMs just begged to be ganged together for polyphony, and the Four Voice, Two Voice, and Eight Voice did exactly this, integrating multiple SEMs with a keyboard and programmer (or sequencer) in a road-case enclosure.
These were transportable but still bulky, and with the ’80s looming (and the competing Prophet-5 dropping in 1977), the market wanted a tighter size-to-polyphony ratio. First came the OB-X — basically SEM circuits under common sheet metal. The late ’70s ushered in integrated circuits, and Oberheim miniaturized the SEM design onto Curtis semiconductor chips.
With a hefty price point for eight voices, the OB-Xa was no impulse purchase but certainly approachable for pros and the committed. It poked the 5-voice Prophet on polyphony and the ability to split the keyboard. Once guitar deity Eddie Van Halen joyfully put the OB-Xa front and center in the “Jump” video, keyboardists either had one or wanted one.
Black and
Blue Beauty
OP-Xa V melds the best of the OB-X, OB-Xa, and OB-8 synths with today’s DAW-centric music workflows.
In many ways it’s the most OB you can get outside of having a collection of all three. Here are just a few of the features that set that benchmark.

01. Authentic Oscillators
Triangle, saw, and square waves with variable pulse width, cross-mod from the OB-X, and hard sync create the signature sounds of the ’80s.
02. Flexible FIlters
Choose 12dB filtering for the classic OB sound or 24dB mode for more aggressively resonant timbres.
03. Bend One or Both
We duplicate the original’s option to pitch-bend oscillator 2’s pitch only, for musical statements that sing in intervals.
04. Ultrawide
Adjust the stereo spread of the oscillator, filter, and LFO outputs for fatter bass, more expansive pads, and a truly immersive mix.
05. Standalone Vibrato
A comprehensive vibrato section means you don’t need to tie up an LFO to get this go-to musical effect.
Resurrecting
a titan
Our teams of engineers and audio experts set out to capture every velvety-smooth sinewave, every dazzling sawtooth chord, every detuned sub-rich bass, and every split-keyboard stacked timbre that put the OP-Xa on the map.
To fully experience the majesty and raw power of an instrument like this, samples simply won’t cut it. OP-Xa V is the result of exhaustive measuring, analysis, and reverse-engineering of every aspect of the original instrument - and then some.
The unique behavior and sonic character of the Curtis chips played a crucial role in the colossal sound we know and love; replicating the bite and bark of the Curtis filters was an integral part of nailing OP-Xa V’s sound. We also incorporated some choice cuts from the instrument's famous peers - OB-X and OB-8 - and enhanced them with new features for a supremely authentic and far-reaching analog experience.
