Arturia OB-Xa License - Legendary growl machine

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.

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.

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.

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.

OB Enhanced

The Advanced Panel makes OP-Xa V more powerful than you can possibly imagine.

Once we nailed the sound, we multiplied the modulation possibilities and added effects derived from our FX Collection. It all adds up to an instrument that’s yesterday and tomorrow at once, and a musical force that will always be with you.

Hear it in action

Hip-hop. Cinematic. EDM. Rock. The original OB-Xa won adherents across all musical genres and applications. These demos from our artists and sound designers showcase just a handful of ways OP-Xa V shines.
