Longing to sound like the biggest icons of the 80s? Jump into the dream world of the future by activating the brand new features of the evolved synth.

Immerse yourself in this quirky synth and whip up new songs with the fat, creamy sounds that made it famous. Not only will you feel the original sound of punchy bass, thick analog pads and drones, and cyclical effects at your fingertips, you’ll also have access to brand new features that will bring out this iconic sound deeper than ever. OB-Xa V is here to let you spin that audio hurricane!

OB-Xa V has been one of our most requested synths, so we took extra care to make it more satisfying than you’d ever expect. That’s right - we went back to the future!

Sonic alchemy for the 21st century

OB-Xa was a hugely sought-after synth in its own time. With our carefully thought out features implemented, we made it even more intelligent, intuitive, and inspiring to use.

Stereo spread

The pioneering stereo spread feature lets your ears immerse into sound movement.


The arpeggiator generates expressive patterns and melodies to enhance your musical rhythms.


More flexibility of the LFO allows in-depth sound design capabilities and brings movement and excitement to the sound.

Cross modulation

The oscillators’ continuous cross modulation allows one oscillator to modulate the other one. This leads to frequency modulation, resulting in a nice, metallic sound. It’s parallel to the 0 to 1 switch on the original OB-X hardware.

Oscillator’s mix

Oscillators’ mix in the filter section lets you take your sound sources and craft them to achieve the end result you desire.

Well, as both a by-nature-virtual-synth-sceptic, and an OB-Xa owner, the first thing I am required to do with any software that purports to be a clone of hardware device is to fire up said hardware device, and A/B the two. The tonality of the two are effectively indistinguishable. This is shockingly good.

The OB-Xa is one of my favourite synths ever and this plug-in definitely doesn't disappoint. Sounds and looks amazing. It makes you feel like you're surfing on a hologram in 1984

I opened the OB-Xa in trailer project I was working on and holy s...ynths does this one sound good! It went straight into this project after designing my first sound within minutes. I never owned an OB-Xa, but I was able to work and play with a bunch of different Oberheims over the years. Great to get another piece of that in software form

Full of vibrant soundscapes, vivid textures and countless variables to play with – the OB-Xa V has quickly become my new favourite Arturia toy and staple synth to use when I create.

As a big fan of Vangelis type of sounds, big synths like the OB-X are amongst my favorites. The OB-Xa is a beast for me, I’ve waited for so long to have a good emulation of the original synth. I can easily manipulate the parameters and achieve pretty big strings and arpeggio. It's a must.

Re-enter the synth universe at its prime and go wild with previously impossible synthesizer technology

It’s easy to get lost in endless inspiration without an organizing system to ground it – and that’s why our sound libraries offer a super easy system of categories and tags. Create your own patches while browsing hundreds of presets for an instant revisit when you need it. It’s sonic exploration made easy.

Sound Corner

Discover the sonic universe of OB-Xa V and play with its fat, flexible sound. To match OB-Xa’s epic legacy, create an incredibly wide sound by activating the stereo mode and turning the spread knob. Thanks to VCA parameters, you’ll be able to create swirling effects that are going to detonate your eardrums. By doubling up the original polyphony of 8 to 16, a rich, complex sound will amaze all your listeners. Make your inventions really glow with effects including reverb, delay, chorus, and overdrive. Combined with the pattern-based arpeggiator and the creative function generators, your sound design universe will be changed forever.
