Ten-hand piano: A networked music installation

This paper presents the latest developments of the Public Sound Objects (PSOs) system, an experimental framework to implement and test new concepts for Networked Music. The project of a Public interactive installation using the PSOs system was commissioned in 2007 by Casa da Musica, the main concert hall space in Porto. It resulted in a distributed musical structure with up to ten interactive performance terminals distributed along the Casa da Musica’s hallways, collectively controlling a shared acoustic piano. The installation allows the visitors to collaborate remotely with each other, within the building, using a software interface custom developed to facilitate collaborative music practices and with no requirements in terms previous knowledge of musical performance.
