title: The preservation, emulation, migration, and virtualization of live electronics for performing arts: An overview of musical and technical issues
abstract: Centers for electronic music creation now face strong difficulties to reperform important works considered as belonging to their repertoire.

Sustainability can be achieved in four different ways that are examined in this article: preservation, emulation, migration and virtualization. We discuss these issues, showing the first steps towards solutions at Ircam in the framework of the European project Caspar.
