Composing Interface Connections for a Networked Touchscreen Ensemble

In this paper, we explore new ways to compose networked interactions for ensemble performance using touchscreen instruments. We introduce a web-based touchscreen instrument modelled on classic synthesiser designs and a system for linking interface elements from this instrument between multiple members of the ensemble. We discuss our composition system and syntax that allows these network links to be scripted allowing a mode of performance inspired by open-form composition. The experience of composing and performing with these systems is investigated through co-located live and studio performances. Our findings support the utility of the system for improvisations and suggest ways to improve the system to cope with larger numbers of network links to enable more exciting performances.
