Field Transfer projects the sounds from an analog circuit into juxtaposition with facets of raw digital audio. As a performer interacts with the circuit—which consists of two square-wave oscillators activated by pressure sensors and shorting disks—instances of pulsed and modulated sound are triggered in the laptop in a manner that couples the analog and digital sources together. Sudden change in the circuit can act as a trigger for starting sound, interrupting sound, and redirecting sound in the laptop. The circuit audio can also drive the laptop to track in harmony at times.
