“Improvisession-II”: A Performing/Composing System for Improvisational Sessions with Networks

This paper is intended as an investigation of new interactive environment in music. I will describe two types of performing/composing systems for improvisational sessions with networks and a concept called “GDS (Global Delayed Session) music”. These systems are called “Improvisession-I” and “Improvisession-II”, and this paper reports not only the basic idea but also the latest version and applications in education and entertainment.
