The Gelmetti Machine is a software instrument developed in Max/MSP that simulates the sound of no-input mixing.

Once triggered by an impulse response the feedback system wavers around, and settles upon, feedback lines from speaker to microphone. Inspired and named after Vittorio Gelmetti the electroacoustic composer who worked with Michelangelo Antonioni on the film Deserto Rosso, the Gelmetti Machine is designed as a tool for generating Gelmetti’s signature atmospheres and sonic ambiences. Excepts of the software in an installation context are above.
