Dextoria - An embedded system to control electric guitar effects via sound-producing gestures

Proceedings of the International Conference on New Interfaces for Musical Expression

Abstract:

Standard guitar effects pedals are limited in their control possibilities, difficult to access on stage, and challenging to operate while playing. Innovative control systems are often not well integrated into the common guitar playing environment. In this paper we present “Dextoria” -- a control system that allows guitarists to make additional use of their sound-producing hand gestures. With the fretting hand, guitarists can switch between two effect loops, depending on the hand’s fret position that is measured by a distance sensor on the guitar’s headstock. The posture of the picking/strumming hand is captured by an IMU sensor on a hand strap, in order to control guitar effects pedals that have an expression input. The Dextoria system is modular and embeds into guitarists’ existing live setups.
