OM

In 1928 French cellist Maurice Martenot invented an electronic musical instrument he named ondes Martenot. He created four different speakers for the instrument, one of them was the Métallique, that featured a gong instead of a speaker cone.  

‚OM‘ belongs to a tradition of creations by artists and instrument builders keeping Martenot‘s ideas alive. Various models in different sizes and shapes are in the planning.
