In this article we describe a new approach to performing musical works that use Yamaha DX7-based synthesis. We also present an implementation of this approach in a performance system for Madonna of Winter and Spring by Jonathan Harvey. The Integra Project, ‘A European Composition and Performance Environment for Sharing Live Music Technologies’ (a three year co-operation agreement part financed by the European Commission, ref. 2005-849), is introduced as framework for reducing the difficulties with modernising and preserving works that use live electronics.
