Multimodal guitar: A toolbox for augmented guitar performances

Abstract

This project aims at studying how recent interactive and interactions technologies would help extend how we play the guitar, thus defining the “multimodal guitar”. Our contributions target three main axes: audio analysis, gestural control and audio synthesis. For this purpose, we designed and developed a freely-available toolbox for augmented guitar performances, compliant with the PureData and Max/MSP environments, gathering tools for: polyphonic pitch estimation, fretboard visualization and grouping, pressure sensing, modal synthesis, infinite sustain, rearranging looping and “smart” harmonizing.
