Apparatus and system for realizing cooperative performance by plural people

摘要

PROBLEM TO BE SOLVED: To provide technical means that can easily realize diverse musical expressions and a novel form of performance that can make multiple performers feel a sense of togetherness.SOLUTION: A coordinated performance system 1 comprises a coordinated performance control device 10, a sound source 20 and a plurality of terminal devices 30. Before beginning performance, the coordinated performance control device 10 determines performance parameters regarding which of various control parameters for controlling the sound source 20 should be provided by which terminal device 30. During performance, the coordinated performance control device 10 acquires performance parameters generated by operation of terminal devices 30 by users, and generates control parameters having new contents on the basis of the performance parameters. The sound source 20 generates and emits synthesized singing voices on the basis of the control parameters generated by the coordinated performance control device 10.
