Tectonic: a networked, generative and interactive, conducting environment for iPadThis paper describes the concepts, implementation and context of Tectonic: Rodinia, for four realtime composer-conductors and ensemble. In this work, an addition to the repertoire of the Decibel Scoreplayer, iPads are net-worked together using the bonjour protocol to manage connectivity over the network. Unlike previous Score-player works, Rodinia combines “conductor view” con-trol interfaces, “performer view” notation interfaces and an “audience view” overview interface, separately iden-tified by manual connection and yet mutually interactive. Notation is communicated to an ensemble via scores in-dependently generated in realtime in each “performer view” and amalgamated schematically in the “audience view” interface. Interaction in the work is enacted through a collision avoidant algorithm that modifies the choices of each conductor by deflecting the streams of notation according to evaluation of their “Mass” and proximity to other streams, reflecting the concept of shift-ing Tectonic plates that crush and reform each other’s placement.
