The user terminal unit null multiple user terminals which are used for the music session system and this music session

摘要

PROBLEM TO BE SOLVED: To provide a mechanism having high scalability in the number of participants and an environment in utilizing a communication network to perform a music session.;SOLUTION: In this music session system, a plurality of nodes (user terminal) N1 to N7 are connected in a communicable way through the communication network, and each of the nodes can bidirectionally transmit and receive performance data to/from an adjacent node. Each of the nodes N1 to N7 reproduces data performed by its own instrument and performed data from the adjacent node based on performance and transmits the data performed by its own instrument to the adjacent node. In a node (N2 to N6 of (a), N3, N4 and N6 of (b) and N4 of (c)) to which a plurality of adjacent nodes are connected, further transmits received performance data from a certain adjacent node to different adjacent nodes. The performance data are transmitted at every musical delimitation such as a bar and synchronized with timing corresponding to the delimitation to be processed in each node.;COPYRIGHT: (C)2004,JPO
