A Distributed Cooperative System to Play MIDI Instruments

(RMCP: Remote Media Control Protocol)

This project is proposed by Masataka Goto.

Japanese version is here.

We have developed a distributed cooperative system, which integrates MIDI and LAN. This system allows users to play an ensemble with computer support. Because of the integration of MIDI and LAN, various kinds of support are obtained by exploiting existing computers without special MIDI materials. For example, the users may play a local/remote session through a computer network. They also may see visualized information of other users' play, and computer graphics reacting to the play.

To facilitate system implementation and expansion, we designed the Remote Music Control Protocol (RMCP), which is an extension of MIDI protocol; it supports information sharing by broadcast and time scheduling using time stamps, for example. This system was implemented on workstations connected to Ethernet. In our experience, several users were actually able to play an ensemble.

We have extended the traditional RMCP and developed the Remote Media Control Protocol Version 3.0 (RMCPv3) for more general purposes. RMCP is a communication protocol on the UDP/IP between servers and clients in the distributed cooperative system. RMCP is designed to transmit symbolized multimedia information through networks.

We have also developed an RMCP gateway which makes it possible to use RMCP over the Internet.
