Used Wersi Sonic OAX1 Organ


The Wersi Sonic OAX1 is the flagship Wersi arranger keyboard from the OpenArt-eXtended series, in White finish. Featuring the new OAX operating system, sound and accompaniment library, the high end features will ensure that you’ll be making amazing music in your home for years to come.

The Wersi Sonic features a high-end FATAR 76-note semi-weighted keyboard that can be played like real piano using a controller pedal. The new Grand Piano Samples are inclusive of the most expressive dynamic layer sounds and go far beyond what Wersi has produced in the past. From full nuances of the grand piano or an acoustic nylon guitar, the Sonic OAS keyboards allow you to play in the most expressive way.

Famous Predecessor

The Abacus KS1 was the world’s first keyboard to include a complete Windows PC, setting new standards for electronic instruments. The new OAX1 continues in this fashion and shows itself as a modern and innovative keyboard. The current Windows 10 operating system, the fast processor, intuitive operation and the certainty of being equipped for the future are highlights of the OAX1.

Real-Time Operation

During the development of the OAX1, special emphasis was placed on simple and direct operation. The large number of controls, their logical arrangement and the 13.3″ touch display make operation of the OAX1 child’s play. The volume of the manuals and the accompanying tracks can be changed at any time using convenient drawbars. So you always have direct access while playing.

Variable Drawbar Sounds with the OX7 & VB3

The sound of the Sinus drawbars will always be associated with names such as Klaus Wunderlich, Franz Lambert or Jimmy Smith, who have given this sound with its typical playing style an unmistakable identity. Vary the organ sound in real time using the 9x Drawbars (Upper/Right) and 7x Drawbars (Lower/Left).

Great Sound

Experience the unique sound of the OAX system via the integrated loudspeaker system with an output power of 2x 60W. Equipped with new multi-layer dynamic long wave samples recorded with high quality Neumann studio microphones, the Wersi OAX Sound Library offers guitars, dynamic violins, cellos, pan flutes, synths and orchestral/brass sounds. You also have access to a new library of accompaniment sounds that have been perfected with insert effects for even greater satisfaction. Some of the best of the OpenArt-Arranger styles have been included, but a whole new Accompaniment library has been created for the Sonic. The Sonic features a new OpenArt-Arranger (Accompaniment Editor) with new functionality and Style options.

The “Easy Play” Concept

The Wersi Sonic OAX-1 can be played in ‘Easy Mode’ like a traditional organ so no matter your ability, the Sonic offers you the easiest playing experience. Switch to Expert Mode to learn new functions form the built-in demo facility and begin to setup your Sonic with possibilities like never before. An intuitive multi-touch display in a modern 16:9 resolution allows you to flick through pages with a quick gesture of your hand.

Unique Wersi Tones

The Sonic has many great sounds made possible by newly developed audio boards. Listen to the winds, the convincing grand piano, the choirs, the great strings with huge kettledrums in the low keys. There are many highly authentic synthesiser sounds that can otherwise only be found on the most expensive synthesisers, and of course the fascinating organ sounds, which can be operated via drawbars. Special sound effects can be controlled via the After-Touch function, which is available on both manuals of the Sonic. For example, control the vibrato of the panpipe by pressing the key slightly. Open the filter on synthesiser tones or turn your trumpets into fantastic shake trumpets. You can’t describe it – you just have to feel it.

Wersi Drawbars

For the true organ experience, drawbars provide an intuitive method for altering the sound without distracting from creativity. The Wersi Drawbars allow you to play the classic sounds via the VB3, leaving you very close to the old electromechanical sound: Yes, it is the sound of the classic sound wheels!

Integrated Synthesiser

A professional and very flexible synthesiser has been integrated into the Sonic. With 3x oscillators, analogue/wavetable synthesis, bold unison waveform and multimode filters, over 400x modern synthetic tones are available, alongside a convincing Arpeggiator.

Fantastic Grand Piano Sounds

Experience the natural and unmistakable sound of a large concert grand piano, whose sound diversity covers all musical genres such as classical, jazz, musical and pop. 6x dynamic layers plus an additional soundboard with a memory capacity of 1GB are available so that you can reach the entire sound spectrum from soft pianissimo to powerful fortissimo.

Fabulous Strings

Be it moving film music, sophisticated classical compositions or emotionally charged ballads – here you will find a symphony and a chamber orchestra with strings, brass, woodwinds and fantastic orchestra percussion at the push of a button. No more tedious composing of individual tones – finally you can concentrate on the essentials. You will conduct and play your Sonic orchestra with joy and ease.

Realistic Choirs

The Sonic offers extremely realistic and expressive choral tones, whether jazzy scat singing, classical choir or modern pop vocals.

Real Accordion Sounds

As soon as you select Accordion-Live, an original accordion register bar appears in the display. If you switch from one tab to the other, you will also hear the original toggle click. And then the sounds! You can find all common accordion sounds. Genuine sonorous Hohner Morino sounds, the beautiful double octave sound (4x feet with 16x feet) or the famous French musette accordion, in which the individual choirs are slightly out of tune with each other and thus produce the lively floating musette sound. It is very effective for playing French accordion chansons or the world-famous Styrian button accordion sounds.

Sonic-Accompanying Tape

The incredibly realistic drum grooves are real drum sounds that have been recorded in the recording studio with many microphones and stored. The bass sounds are just as good, whether electric bass or the acoustic bass. These two also sound incredibly real and fascinating. Furthermore, a modern multimedia player is available for many formats.

State-of-the-Art Hardware & Software

With a quad core processor and the latest PC technology, the Wersi Sonic OAX-1 offers unlimited polyphony, a huge internal RAM memory storage for a speedy performance, and VST 3 Studio Instruments fully integrated.
A new audio board with excellent technical data has been developed for the OAX system. This results in the clear and warm sound of the organ. Windows 10 64-bit and the powerful PC components such as a strong CPU, fast RAM and the SSD hard disk are the basis for a modern and future-oriented musical instrument.
