MOS (Mountain Operated Synthesizer)

MOS (Mountain Operated Synthesizer) is a device that uses an array of sensors and analogue components to make the environmental changes in the earth and air of the Merapi Volcano audible.

"Developed as a response to the extremely lively, fertile and volatile site itself. The work is intended as an offering to the mountain and to the people who might happen to encounter the work while walking up. MOS is a synthesiser built for the mountain itself to play and perhaps express its nature.
The second base camp is about 2000 meters up the active volcano and takes approximately 3 hours to hike. The work is powered by solar and is installed with the intention to remain there." - Pia

in collaboration with Pia Van Gelder and Andreas Siagian as part of the instrument builders residency.
