Abstract

In a plurality of rooms, hubs are installed to build a star-shaped LAN, and tone-generation-related devices, such as a keyboard, tone generator device and speaker, are connected to the respective hubs. For example, in an internal network, the keyboard is logically connected to an input side of the tone generator device and a speaker is connected to an output side of the tone generator device, so as to build a tone generation system. The tone-generation-related devices are provided with respective network adaptors so that they can be readily connected to the LAN. Communication is carried out between the tone-generation-related devices, using a communication protocol intended for retransmission control. Each of the tone-generation-related devices is in the form of a processor device, which executes a program corresponding to a function of a desired processing element to thereby implement the desired processing element. Once a given tone-generation-related device, implementing a plurality of processing elements, is connected to the network, an internal connection between the processing elements is canceled.

Claims

1. A tone generation system composed of a server and a plurality of processor devices connected to a star-type network, said tone generation system comprising:

said plurality of processor devices that function as tone-generation-related processing elements corresponding to respective programs executed in the processor devices; and

said server that manages unique identification information, in the network, set for individual ones of the processing elements functioning in said plurality of processor devices,

wherein, between said server and any one of said processor devices or between said processor devices, communication is carried out on the network using the unique identification information, and

wherein, when a connection is to be made between given processing elements on the network, not only a connection between a connection-originating processing element and a connection-partner processing element of the given processing elements is established, in a first processor device functioning as the connection-originating processing element, in accordance with a setting for connecting between the connection-originating processing element and the connection-partner processing element, but also a connection instruction for connecting between the connection-partner processing element and another processing element is sent to a second processor device, functioning as the connection-partner processing element, to thereby establish a connection between the connection-partner processing element and the other processing element in accordance with a setting for connecting between the connection-partner processing element and the other processing element.

2. A tone generation system as claimed in claim 1 wherein, when the connection is to be made between the given processing elements on the network, connection information indicative of the setting for connecting between the connection-originating processing element and the connection-partner processing element of the given processing elements and connection information indicative of the setting for connecting between the connection-partner processing element and the other processing element is recorded into a connection buffer, and

the connection between the connection-originating processing element and the connection-partner processing element is established in said first processor device on the basis of the connection information recorded in the connection buffer, and a connection instruction for connecting between the connection-partner processing element and the other processing element is sent to said second processor device to thereby establish the connection between the connection-partner processing element and the other processing element on the basis of the connection information recorded in the connection buffer.

3. A network processing method for use in a tone generation system composed of a server and a plurality of processor devices connected to a star-type network, said tone generation system including:

the plurality of processor devices that function as tone-generation-related processing elements corresponding to respective programs executed in the processor devices; and

the server that manages unique identification information, in the network, set for individual ones of the processing elements functioning in the plurality of processor devices, said network processing method comprising;

a step of, between said server and any one of said processor devices or between said processor devices, carrying out communication on the network using the unique identification information;

a step of, when a connection is to be made between given processing elements on the network, establishing a connection between a connection-originating processing element and a connection-partner processing element of the given processing elements, in a first processor device functioning as the connection-originating processing element, in accordance with a setting for connecting between the connection-originating processing element and the connection-partner processing element; and

a step of sending a connection instruction for connecting between the connection-partner processing element and another processing element to a second processor device, functioning as the connection-partner processing element, to thereby establish a connection between the connection-partner processing element and the other processing element in accordance with a setting for connecting between the connection-partner processing element and the other processing element.
