In the 1930s the dominance of Mortier was matched by the instruments from the firm of Gebroeders Decap Antwerpen (Dutch for Decap Brothers Antwerp). By the end of the 1930s both Mortier and Decap had reached their zenith both in art-deco facade design and musical abilities. Dance organs came in every size. More compact versions were used in cafes and smaller public venues where they bridged the gap between orchestrions and the giant dance organs. Just like many cafe coin pianos and orchestrions some of the smaller instruments were set up so that they could be coin-operated remotely.
