This thesis presents the development of a live-looping system for gesture-to-sound mappings built on a connectivity infrastructure for wireless embedded musical instruments using a distributed mapping and synchronization ecosystem. Following the recent trend of Internet of Musical Things (IoMusT), I ported my ecosystem to an embedded platform and evaluated in the context of the real-time constraints of music performance such as low latency and low jitter. On top of the infrastructure, I developed a live-looping system through three iterations with example applications: 1) a wireless Digital Musical Instrument (DMI) with live-looping and flexible mapping capabilities, 2) an embedded loop synthesizer, and 3) a software harp synthesizer/looper with a graphical user interface. My final iteration is based on a novel approach to mapping, extrapolating from using Finite and Infinite Impulse Response filters (FIR and IIR) on gestural data to using delay-lines as part of the mapping of DMI’s. The system features rhythmic time quantization and a flexible loop manipulation system for creative musical exploration. I release my tools as open-source libraries for building new DMI’s, musical interactions, and interactive multimedia installations.
