Antescofo is a modular anticipatory score following system that holds both
instrumental and electronic scores together and is capable of executing
electronic scores in synchronization with a live performance and using
various controls over time. In its very basic use, it is a classical score
following system, but in advanced use it enables concurrent representation
and recognition of different audio descriptors (rather than pitch),
control over various time scales used in music writing, and enables
temporal interaction between the performance and the electronic score.
Antescofo comes with a simple score language for flexible writing of time
and interaction in computer music.
