Real-time operation

During the development of the OAX1, special emphasis was placed on simple and direct operation. Due to the large number of operating elements, their logical arrangement and the 13.3″ touch display, operating the OAX1 is child’s play. The volume of the manuals and the accompaniment tracks can be changed at any time using the convenient drawbars. This way you always have direct access to the most important settings even while playing.


Variable Drawbar Sounds with the OX7 and VB3

A novelty with keyboards is the direct operation of the foot rests via “real” drawbars. With 9-fold Drawbars for the right half of the game and the 7-fold Drawbars for the left half of the game you have a direct influence on the typical drawbar sound colours of WERSI or the unique sound of the electromagnetic organs including rotor effect.

Overview of all OAX1 features


Idea with a future – Full software control of all functions and sounds, constant further development of the OAX overall system, updates possible via download – the times when every change required complex and expensive hardware modifications are now a thing of the past.
