A consort of gestural musical controllers : design, construction, and performance

This thesis project presents the T-Sticks, a new family of digital musical instruments (DMIs). Most DMIs are either entirely unique interfaces, or exist as design iterations in which each incarnation is intended to improve on the last. The T-Sticks are instead intended to form a complementary group or consort which may be performed ensemble and also performed individually in solo pieces or works for mixed instrumentation. Each of the T-Sticks is based on the same general structure and sensing platform, but each also differs from its siblings in size, weight, timbre and register.This document explores some of the issues challenging and motivating the field of DMI design and performance, and describes the motivations behind the T-Stick project in this context. Several existing DMIs are examined for similarities to the T-Stick and compared in terms of design intention, implementation, and usage. The hardware and software designed and built for this project is presented, along with insights gained through collaboration with performers and composers in the context of McGill University's Digital Orchestra project. The performers in question have collectively practiced and performed with the T-Stick for hundreds of hours in the lab, practice room, and on the concert stage. The consort of T-Sticks will be featured as an ensemble in a piece to be performed during the 2008 MusiMarch festival in Montreal
