An interactive sound synthesis exhibit stands against a plain white wall in an indoor public exhibition space in Budapest, Hungary. To the left, a large glass partition reflects interior elements, indicating a modern building. The exhibit consists of a black base console featuring a central 18-key piano-style keyboard, numbered 1 through 18. Flanking the keyboard are two embedded circular black objects, likely speakers or control knobs. Above the base, a light-colored wooden frame supports a clear glass display case. The lid of this case is propped open at an angle by two brass-colored rods. The underside of the lid displays a white panel with 18 numbered black graphic illustrations and accompanying Hungarian text that details various sound synthesis methods, including waveform types, mechanical representations, and sound generation techniques (e.g., "Telefonom," "Hangszerelés," "Fizikai modellezés"). Visible through the clear glass top of the display case are internal mechanical and electronic components, including a series of levers or actuators connected to the keyboard, and an electronic circuit board with an illuminated blue LED on the right side. The black base shows minor surface wear. No individuals are present in the scene.
