Honing, H. (1990). POCO: an environment for analysing, modifying, and generating expression in music. In Proceedings of the 1990 International Computer Music Conference. 364-368. San Francisco: Computer Music Association.
POCO is a workbench for analysing, modifying and generating expression in music. It is aimed to use in a research context. A consistent and flexible representation of musical objects and structure was designed. The integration of existing models of expression made it possible to compare and combine these models using the same performance and score data. New tools were developed for specific "micro surgery" on expression. A lot of attention was given to the openness, integration, and extendibility of the system.
