Abstract

This paper describes the development so far of a system that uses multiparametric controllers along with an interactive high-level search process to navigate timbre spaces. Either of two previously developed interfaces are used as input devices; a hand tracking system and a malleable foam controller. Both interfaces share the property of streaming continuous multiparametric codependent data. When these data streams are mapped to synthesis parameters, the controllers can be used to explore the parameter space in an embodied manner; with the hand tracker, moving or changing the shape of the hand changes the sound, and with the foam, deforming its shape changes the sound. The controllers become too sensitive with larger parameter spaces, so a navigation system was developed to enable high level control over the subset of the parameter space in which the controllers are working. By moving and refining the working range, a timbre space can be progressively explored to find a desired sound. The search process was developed by focusing on three scenarios, the control of four, ten and forty dimensional timbre spaces. The system is used bi-manually, while one hand is used for detailed search with one of the input devices, the other hand controls high level search parameters with MIDI and the computer keyboard. Initial reactions from two musicians indicate the development so far to be successful, the next stage in this project is to carry out formal user studies.
