Tactus was originally written for fixed media and the Spatially Distributed Vibrotactile Actuator Array (SDVAA); an installation with ten actuators that are synchronized with sound. The title of the work is in reference to both the takt (underlying musical pulse) and the tactile sensory system. Since rhythm lies at the intersection between these two faculties, it was used as a main structural element. The source materials were gathered from digital waveguide strings in Pd. This patch produced quasi-granular textures, that when time-stretched in a DAW, yielded unexpected and surprising sounds. Tactus has since been revised and exists both as part of the SDVAA installation and as a 2-channel piece for fixed media.
