MATRIXHARP is a prototype controller that rethinks modular interfaces. The interface utilizes stretch sensors to modulate parameters and capacitive sensors to make patch connections. Through this interface, patching and moving through the spectra of parameters becomes a tactile and embodied action, one less concerned with metrics. Patch connections are felt throughout the system through the physical tension of the stretch sensors being pulled and pushed. This interface also evades the “male” and “female” language of standard modular patching.
