Innovative Sound and Technology – The new OAX-Keyboard!


immediately available7.990€ORDER ONLINEFamous predecessor - The ABACUS KS1 was the first keyboard in the world to be based entirely on a complete Windows PC and thereby sets new standards. The new OAX1 continues trailblazing by presenting itself as a modern and innovative keyboard. The latest operating system Windows 10, a fast processor, the intuitive operation and the certainty to be prepared for the future, are highlights of the OAX1.


76 Key Deluxe Keyboard  - The high-quality 76-key keyboard lets you distribute up to 16 timbres on the keyboard. With sophisticated dynamics and aftertouch, you can add the finishing touches to the sound.


Real-Time Operation - During the development of the OAX1, particular emphasis was placed on simple and direct operation. Due to the large number of controls, their logical arrangement and the 13.3 "touch display, controlling the OAX1 is child's play. The volume of the manuals and the accompanying tracks can be changed via comfortable drawbars at any time. This gives you direct access even during playing.


Variable drawbar sounds with the OX7 and the VB3 - The sound of the Sinus drawbars will always be associated with names like Klaus Wunderlich, Franz Lambert or Jimmy Smith, who have given this sound a distinctive identity with their typical playing style. Vary the organ sound in real time via the 9 drawbars (Upper / Right) and 7 drawbars (Lower / Left).
