Legendary growl machine
The OP-Xa V takes the immense analog power of the fat, aggressive sounding OB-Xa from the 80s charts to the modern era. Faithful to the sound of the original and supercharged with new features, OP-Xa V will take you for a wild sonic ride.
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.

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.

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.
Flexible FIlters
Choose 12dB filtering for the classic OB sound or 24dB mode for more aggressively resonant timbres.
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.
Ultrawide
Adjust the stereo spread of the oscillator, filter, and LFO outputs for fatter bass, more expansive pads, and a truly immersive mix.
Standalone Vibrato
A comprehensive vibrato section means you don’t need to tie up an LFO to get this go-to musical effect.

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.
