Diffractive Constellations is a live performance and research project that combines an acoustic violin with a set of bespoke Eurorack modules programmed in Max/Gen and embedded on the Daisy Seed SOM. By capturing, transforming, and re-sequencing violin gestures, these modules operate as compositional fragments that can be patched together in myriad ways. Each module began as a "composition made parametric," evolving through hardware constraints to support improvisatory practice. This document details the technical design and performance methodologies of six custom modules—called Arvo, Glacial, Detritus, Volution, Widgets, and Forest—highlighting how each processes violin-derived or other input to create layered, time-stretched, and/or autonomous sonic behaviors. These modules collectively shape a system in which performer and electronics co-create emergent musical structures.
