Arturia’s modeling expertise
reinvents the legendary synth
that helped define 80's pop.

OB-Xa made a huge entrance into the music making world in December 1980. Its high-end synth artistry clear from its complex construction, impressive power, and a big, fat sound reintroduced a sense of ambition back to the synth universe and had an undeniable impact on the future of music creation. Soon enough, the OB-Xa claimed its place in the synth hall of fame.

The main upgrade from its predecessor, the OB-X, was switching from discrete circuitry to integrated Curtis chips, which resulted in greater stability in all Oberheim®’s instruments. Although OB-X had a creamier sound due to its discrete SEM 12dB/oct state variable filter, OB-Xa offered two switchable filter modes: 12 dB/oct (2-pole) and 24 dB/oct (4-pole), leading to a slightly more aggressive sound. This punchy signature sound created by Oberheim® made the OB-Xa V the bread and butter synth of the 80's.

Accessible digital synthesizers became highly popular at the time, unleashing their creative sonic capabilities to the mass audience. The famous Prophet 5 had its own unique properties and an impressive array of controls. Then, the OB-Xa was revealed and not only surpassed other available synths on the market, it blew the competition away. OB-Xa brought a huge 8 voice polyphony, deep control with the LFO capabilities, and a physically impressive size to house the circuitry and power. The synthesizer world has never been the same since.

OB-Xa’s most recognizable sound is the synth part from Van Halen’s ‘Jump’, and it featured heavily in music released throughout the 80’s all the way through to today. The artists that made music history with the help of this noble machine include Prince, Billy Idol, Chaka Khan, Bon Jovi, Vangelis, and Gary Numam. The sound of this synth is far-reaching and adapts beautifully to power ballads, seductive stories, and rebellious roars. It’s used today by the likes of Flume, Chrome Sparks, Calvin Harris, and Venetian Snares, entering a new dimension of electronic music.

Whether you’re reliving or just discovering the seduction of this sound, this is the most authentic software you could wish for. With added polyphony, wide stereo spread, and even more flexible LFOs, OB-Xa V is the perfect mix of the past and the future.

Reinventing what works
at a supreme level

Settling for sampling synths will never be fully satisfying. Immerse yourself in a tool that will listen to your instinct and inspire new ideas.

We analyzed and measured the original hardware units closely. We took particular focus on recreating the Curtis filters as an integral part of the OB-Xa V. We also incorporated the best out of OB-X and OB-8 and added new features that enhance the musical experience of this synth. Applying this with our own technology leads to truly incredible results.

Create the sounds of the future by using the best of both worlds.

Deep engineering insights

When it comes to emulating iconic sounds from the past, the process can get quite complex. But this is what Arturia’s all about – expert emulation straight from the brains of top audio engineers. We’ve got you covered!

We love making you happy – and thanks to the impeccable engineering skills and deep understanding of technology by our talented team of engineers and sound designers,

you can really trust the internal workings of this software to bring out the sound you want.

Significant tweaks with a huge impact,
all in a sleek design

We want you to enjoy the fullest spectrum of music production in the most straightforward way possible.

That’s why we’ve combined the original OB-Xa with the best features that OB-X and OB-8 had to offer, and we left out the elements that would be in the way, such as the multitimbral part of the original instrument. The clean interface of OB-Xa V will be a joy to have a dialogue with. Even if this is the first time you’re using this synth, this virtual instrument will open itself up to you.

Polyphony

We doubled the original voice polyphony of 8 to 16, so your sound can be bigger than ever.

More flexibility on the LFO

Our designers included additional waveform shapes and synchronization by time division to the DAW bpm. We’ve added a key trig function to reset the LFO every time the note kicks in.

It is a stereo LFO, which means it duplicates the LFO signal to the right and left channels. You can also set the offset with the Stereo Trimmers, which is an unusual approach to the LFO not seen in many other instruments.

Oscillator’s continuous cross modulation

Cross modulation is a specific type of modulation, where an oscillator's frequency is being modulated by the output signal of another oscillator. On OB-Xa V, there are two oscillators. Turn up the X-Mod knob to modulate the frequency of Oscillator 1 with Oscillator 2’s audio signal. Use this feature to change the timbre of the sound.

Stereo spread

This is a unique feature you haven’t seen in other virtual instruments yet, which makes OB-Xa V a truly special combination of features. It’s a clever design trick that allows for a wide stereo spread, causing the stereo image to be more interesting and unusual. This will transform the signal coming out of the LFO, Oscillators, and Filters to make it swirl across the whole stereo image.

Arpeggiator

You can create fast and dynamic sequences by playing just a few keys to create a wide range of patterns. Advanced options include octaves, directions, and rate available as the modulation destination.

Oscillator’s (1, 2, noise) mix in filter section

The mixer section on the original OB-Xa only had an on/off switch for Osc 1 and noise, and a half/full button for Osc 2. We decided to give you much more flexibility with mix knobs that allow for creating more detail within the volume range of each source.

Function generators

We’ve developed 4 bi-polar digital function generators that you can route to any and every parameter on the instrument. Each of them are variable in length with up to 16 points, with slopes that can be controlled per segment and optional quantization. Loop and sync them to your host to use these function generators as pumped up envelopes, raging LFOs, or dynamic step sequencers.

OB-Xa V has 4 function generators that can be switched into polyphonic mode. For example, you can modulate the arpeggio’s rate and the cross-modulation of the oscillators.

On-board FX

The built-in sound effects include a satisfying selection of complete effects, featuring: delay, chorus, reverb, phaser, flanger, compressor, overdrive, multimode filter, and bitcrusher. The world is waiting to hear you roar with fresh, juicy creations!

Back to the present

Make original music with no unnecessary hassle

All our virtual instruments are designed with a sonic heart in mind. Everything that can be easy is easy, and navigating the complex functions of the synth is intuitive and will soon feel like second nature. We make all our equipment to feel like it listens to your creative instincts. It’s not quite telepathy yet - but we’re getting there!
