FIG. 3 is a block diagram of an embodiment of the adapter 11 and the sound generator 15. The adapter 11 includes a microprocessor 20, a modem interface 21, a line connection interface 22, a remote control interface 23, a hard copy interface 24, a read memory 25, a read / write memory 26, a display control 27, an image memory 28, a memory control 29, and a display signal synthesis 30. , A floppy disk interface 32, a musical tone generating interface 34, and a synchronizing signal / various clock generator 31.
The microprocessor 20 has peripheral devices 21 to 21.
It waits for an interrupt from 29, 32, or 34, determines the contents of the interrupt processing in response to the interrupt, and performs data transfer, data conversion, and data operation with each peripheral device. For example, when the remote control receiving unit receives the request, the remote control interface 23 informs the microprocessor 20 of the occurrence and the content of the remote control operation.
Inform Then, the connection is made to the transmission line via the line connection interface 24, and the request content is transmitted to the center via the modem interface 21. When data corresponding to the request is sent from the center, if it is image information, it is written to a write address designated by the memory control 29 in the image memory 28. If the information is music information, the sound generation unit 1 is output via the music generation interface 34.
Send to 5. The procedure of these processes can be designed by a well-known program control by a microcomputer.

The display controller 27 controls the microprocessor 20
In accordance with the instruction, the display signal synthesizer 30 is controlled to output a display signal while reading out the image information written in the image memory 28. As the display signal, the title, number, etc. of the song requested to the television 12 are displayed. In addition,
The display control 27 and the display signal synthesizer 30 can be regarded as an image information processing device.

The sound generator 15 includes a microprocessor 33,
It comprises read / write memories (RAM) 35, 38, read memories (ROM) 36, 37, a bus switch 39, a tone synthesizer 40, and a DA converter 41 . Microprocessor 3
3 performs the following processing. (1) A predetermined processing procedure is started in response to an instruction transmitted by the microprocessor 20 via the music generation interface 34. (2) Write the music information sent via the music generation interface 34 to the RAMs 35 and 38. (3) When writing to the RAM 38, the bus switch 3
Open 9 and close otherwise. (4) In accordance with the music generation instruction given by the microprocessor 20, the performance information in the RAM 35 is read and supplied to the tone synthesizer 40.

The ROM 36 stores a program of the above-described processing procedure. The RAM 35 stores performance data. The ROM 37 stores tone generator parameters of tone colors prepared in advance.

The microprocessor 33 and the RAM 3
5, the ROM 36, the RAM 38, and the bus switch 39 process information relating to the performance, and can be regarded as a performance processing device. The RAM 35 is used as a performance data memory.

5 and the RAM 38 can be regarded as a performance memory.

As the performance information, corresponding to the double tone performance,
For a plurality of parts i = 1 to n, sound source numbers g1 to gn,
These sound source parameters {p1} to {pn}, pair data of pitch and pitch, {P, L} 1 to {P,
Expression data such as L｝ n, tempo data, transposition data, repetition symbol data, crescendo, decrescendo, and the like can be considered. Not all of these are required,
The more data, the richer the expression. If some data is omitted, the abbreviated information is sent, and in that case, a predetermined data value can be used instead. For example, among the sound source parameters that are not transmitted, the parameters stored in the ROM 37 can be substituted.

As the processing of the performance information, it is possible to prohibit the performance of the designated part and perform a so-called minus one performance, or perform the performance for each part.

As the tone synthesizer 40, a tone synthesizer having a plurality of channels, capable of generating multiple tones, and capable of generating different timbres, respectively, is used. Descriptions of these synthesizers are omitted because they are known.

In the above description, the adapter 11 and the sound generator 15 are connected, but they may be used separately. For example, the microprocessor 20 first connects the adapter 11 and the memory 17 and temporarily stores and saves music information in a floppy disk memory. Next, the sound generator 15 and the memory 17 may be connected to transfer music information from the floppy disk memory to the RAMs 35 and 38. In this way, each time music information is transferred from the floppy disk to the RAM 35, 38, the same music is played. The microprocessor 20 and the memory 17 can be regarded as a transmission processing device and a transmission memory, respectively. By the above operation,
Even when music information is supplied from the performance information processing device including the microprocessor 33 to the musical tone synthesizer 40, that is, in the performance state, the image music file 9 is stored in the microprocessor 20 and the memory 17.
Music information is received.

The sound generator 15 may be provided with a keyboard so that it can be played in real time. In this case, the surplus part of the plurality of parts is used for manual performance.

A semiconductor memory may be used instead of the floppy disk memory. The sound source parameters vary depending on the tone synthesis method. In the subtraction method, the transfer characteristic of the filter and the sound source waveform may be sent. In linear predictive coding (LPC) used for speech synthesis, the residual waveform and prediction coefficient, in sine wave synthesis, the spectrum level and phase angle data of each harmonic component, and in waveform synthesis, the sample value of each waveform and , The combined weight coefficient of the waveform, the frequency of the modulated wave and the modulated wave,
The level and the phase angle are the sound source parameters, respectively.

The sound source parameters are usually closely related to the synthesis method of the tone synthesizer 40. However, it is possible to change that parameter to a parameter of a type suitable for another synthesis method. Therefore, the tone synthesizer 4
When a parameter that is not in a format that matches the synthesis method of 0 is sent, conversion may be performed. This conversion can also be performed by the microprocessor 33 and a conversion procedure program.

Note that a receiving device may be provided in place of the above-mentioned line connection device so that the transmitted music information is received and played. For example, in the above description, a request for a desired music has been described. However, when a so-called BGM (background music) is designated by the same operation as above, a predetermined music transmitted from the center 1 is connected to the line connection. The music is received by the user terminal device 6 via the device 10 so that music can be enjoyed.

Further, the image and music file 9 of the center 1 and the terminal device 6 do not necessarily have to be physically at a long distance, but only need to be connectable via a transmission line.
