Gestural interface made from engraved acrylic discs, wood, and light sensors.
Using the structure and hardware that I built for Lobatus, I created a new variation to accommodate a different gestural vocabulary. My interaction with Polvo, with its three circular discs, borrows from the body language of a DJ scratching or spinning to navigate the timeline of a record. Here, I apply similar gestures to extract snippets of field recordings or compositions using a granulation synthesis process.
The granular engravings on Polvo’s discs are a reference this sound process, and they also make the discs easier for me to grasp and operate during performance.
Polvo was premiered in “Hyphen Hub: Repurposed Technology at Creative Tech Week”, where I played it along with a modified blender, a broken oscillating fan, and Espongina.
