Abstract

A plurality of devices connected to a network each includes at least either one or more output plugs for transmitting one or more data streams, or one or more input plugs for receiving one or more data streams, and each of the devices is capable of packeting a plurality of data streams and isochronously transferring the packet to another device in the network. Connection setting program, designed to set connection between a transmission source device and a transmission destination device in the network, includes a step of detecting a predetermined condition for performing automatic setting of logical connection, and a setting step of, in response to detection of the predetermined condition, automatically setting logical connection between the one or more input plugs and the one or more output plugs of the devices. Such arrangements facilitate setting of logical connection between the devices interconnected via the network.

Claims

1. A non-transitory computer readable storage medium storing a connection setting program for causing a computer to perform a method for setting logical connection between the computer and a device in a music system, said music system comprising the computer and one or more devices that are all connected to a network, each of the computer and said one or more devices in said network being capable of organizing a plurality of wave data streams into a packet and isochronously transferring the packet to another device or the computer in said network, each of said one or more devices including at least either one or more output plugs for transmitting one or more wave data streams, or one or more input plugs for receiving one or more wave data streams, the input plugs or output plugs being different in number between the devices, said method comprising:

a step of reading, from a memory, a plurality of automatic connection setting styles in advance of the computer executing the connection setting program;

a step of detecting a predetermined condition for performing automatic setting of logical connection;

a step of, in response to detection of the predetermined condition, detecting a type of each of said one or more devices connected to said network;

a step of determining whether an automatic connection setting style specific to the detected type or types of said one or more devices is included in said automatic connection setting styles; and

a setting step of, when it is determined that the specific automatic connection setting style is included in said automatic connection setting styles, preparing one or more input plugs or one or more output plugs in the computer according to the specific automatic connection setting style and automatically setting at least one logical connection between the one or more input plugs or one or more output plugs prepared in the computer and the one or more output plugs or one or more input plugs in said one or more devices on the basis of the specific automatic connection setting style,

wherein the number of the one or more input plugs or the number of one or more output plugs prepared in the computer by said setting step varies from the number of logical connections set by said setting step, and

wherein the number of logical connections set by said setting step varies in accordance with the specific automatic connection setting style.

2. A non-transitory computer readable storage medium as claimed in claim 1 wherein said predetermined condition is satisfied when software containing at least said connection setting program is installed in the computer.

3. A non-transitory computer readable storage medium as claimed in claim 1 wherein said predetermined condition is when a bus reset has occurred in said network, when another device has been newly connected to said network, or when device-connecting driver software is started up after the computer is turned-on.

4. A non-transitory computer readable storage medium as claimed in claim 1 wherein said wave data stream is a stream of waveform data, and the waveform data are synchronized in sampling frequency between the computer and said one or more devices, and wherein said predetermined condition is when the synchronized sampling frequency is to be changed.

7. A non-transitory computer readable storage medium as claimed in claim 1, wherein the number of input plugs or output plugs included in said one or more devices is fixed.

8. A non-transitory computer readable storage medium as claimed in claim 1,

wherein said method further comprises a step of determining whether log information storing last setting of the logical connection is present, and

wherein, when the log information is present, said setting step is not performed and the computer prioritizes the last setting of the logical connection stored in said log information.

9. A non-transitory computer readable storage medium as claimed in claim 1 wherein said music system includes a memory for storing the logical connection between said devices set by said setting step, and wherein said setting step automatically sets the logical connection on condition that no logical connection between the computer and said one or more devices is currently stored in said memory.

5. A connection setting method for causing a computer to perform processing for setting logical connection between a computer and a device in a music system, said music system comprising the computer and one or more device that are all connected to a network, each of the computer and said one or more devices in said network being capable of organizing a plurality of wave data streams into a packet and isochronously transferring the packet to another device or the computer in said network, each of said one or more devices including at least either one or more output plugs for transmitting one or more wave data streams, or one or more input plugs for receiving one or more wave data streams, the input plugs or output plugs being different in number between the devices, said connection setting method comprising:

a step of reading a plurality of automatic connection setting styles prestored in a memory in advance;

a step of detecting a predetermined condition for performing automatic setting of logical connection;

a step of, in response to detection of the predetermined condition, detecting a type of each of said one or more devices connected to said network;

a step of determining whether an automatic connection setting style specific to the detected type or types of said one or more devices is included in said automatic connection setting styles; and

a setting step of, when it is determined that the specific automatic connection setting style is included in said automatic connection setting styles, preparing one or more input plugs or one or more output plugs in the computer according to the specific automatic connection setting style and automatically setting at least one logical connection between the one or more input plugs or one or more output plugs prepared in the computer and the one or more output plugs or one or more input plugs in said one or more devices on the basis of the specific automatic connection setting style,

wherein the number of the one or more input plugs or the number of one or more output plugs prepared in the computer by said setting step varies from the number of logical connections set by said setting step, and

wherein the number of logical connections set by said setting step varies in accordance with the specific automatic connection setting style.

6. A connection setting apparatus for setting logical connection between a computer and a device in a music system, said music system comprising the computer and one or more devices that are all connected to a network, each of the computer and said one or more devices in said network being capable of organizing a plurality of wave data streams into a packet and isochronously transferring the packet to another device or the computer in said network, each of said one or more devices including at least either one or more output plugs for transmitting one or more wave data streams, or one or more input plugs for receiving one or more wave data streams, the input plugs or output plugs being different in number between the devices, said connection setting apparatus comprising:

a storage section that stores a plurality of automatic connection setting styles in advance;
