LATTICE: STRATEGIES FOR AND AGAINST CONTROL IN AN IMPROVISATION INSTRUMENT
Christopher G. Burns · University of Michigan Library Repository · 2005
Lattice is a laptop improvisation instrument designed to balance user control with unpredictable behavior.The operator triggers synthesis events, specifying their timbre, and upper and lower boundaries on their frequency and duration.The specific frequency envelope and duration of the event are then algorithmically determined, as are all other synthesis parameters relevant to the chosen timbral type.The resulting tension between performer control and algorithmic specification leads to unfamiliar and interesting improvisational situations.The implementation of Lattice also responds to design goals including portability, learnability, and expressive sound synthesis.This paper describes the instrument and its implementation.
