Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to systems and apparatus for providing and reproducing musical information in a manner different from conventional records and tapes.

Conventional configurations and their problems Hitherto, electronic musical instruments that are designed to be played fully automatically are known. These automatic musical instruments include electronic musical instruments that use voltage information to control the pitch and the presence or absence of sound, such as the Musi Sokun Equalizer, and electronic musical instruments that store performance information such as sheet music and control the pitch and sound. The device converts the length information into voltage levels and durations and outputs them to control the music synthesizer. The above performance information is recorded on magnetic tape so that it can be saved or used again for performance. The tone of the sound source of the music synthesizer mentioned above is produced by a voltage-controlled filter or a voltage-controlled filter.
Determined by the frequency characteristics and gain of the amplifier, these can also be generated and controlled as voltages. The voltage information related to the tone mentioned above is also digitized and recorded in semiconductor memory.

It can also be recorded on magnetic tape. However, such performance information and timbre information must be created by the user each time, which is extremely troublesome, making it difficult to reproduce and enjoy music.

Composition of the Invention The music performance device of the present invention includes a music file memory, a transmission line, and a terminal device, and the music file memory stores sound source parameters representing the timbre of the sound source of the musical instrument, and the pitch and length of the musical score. The terminal device records a sound source parameter memory, a performance data memory, a musical tone synthesizer, and supplies the sound source parameters and the performance data to the musical tone synthesizer. A performance information processing device and a request device are provided, and the request device transmits sound source parameters and performance data of a desired song in the music file memory to the sound source parameter memory and performance data memory via the transmission line. The performance information processing device supplies the sound source parameters and performance data to the tone synthesizer to play a desired piece of music.

Waits for an interrupt from 29 + 32 + 34, responds to the interrupt, determines the content of the interrupt processing, and performs data transfer, data conversion, and data calculation with each peripheral device. Let's do it. For example, the remote control interface 23, which receives the request from the remote control receiving section, notifies the microprocessor 2.degree. of the occurrence of the request and the contents of the remote control operation. Then, it is connected to a transmission line via the line connection interface 24, and the request contents are sent to the center via the modem interface 21.

When data corresponding to the request is sent from the center, it is written into the image memory 28.

If it is bad music information, the music generation interface 34
The signal is sent to the sound generation section 15 via the. These processing steps can be performed using a micro combi coater under well-known program control.

The microprocessor 33. RAM35. ROM36
, RAMas, and the pass switch 39 can be regarded as performance information processing devices because they process information related to performances. RAM35 holds performance data memory, and RAM3s
acts as a timbre parameter memory.

The performance information includes sound source numbers g1 to gn for a plurality of pars i-1 to i-n, corresponding to multitone performance.

Those sound source parameters (pl) to (I)n), pair data of pitch and duration, (P,L)i as performance data,
Possible examples include expression data such as ~(P,L)n, tempo data, transposition data, repetition symbol data, talessi end, and decresi end. All of these are not required, but the more data you have, the richer the expression will be. If some data is omitted, the omitted information is sent, and in that case, a predetermined data value can be used as a substitute. For example, for sound source parameters that are not sent out, parameters stored in the ROM 37 can be substituted.

As a process of performance information, it is also possible to prohibit the performance of a designated part, so that a so-called minus one performance is performed, or a performance is performed for each heart.

The musical tone synthesizer 40 has a plurality of channels, can generate multiple tones, and can each generate different tones. Since some of these synthesizers are known, their explanation will be omitted.

In the above description, it is assumed that the adapter 11 and the sound generating section 15 are connected, but they may be used separately. for example,
The adapter 11 and the memory 17 are connected, and the music information is temporarily stored in the floppy disk memory. Next, the sound generating section 16 and the memory 17 may be connected, and the music information may be transferred from the floppy disk memory to the RAM 35.38.

The sound generating section 16 may be equipped with a keyboard so that it can be played in real time. In this case, the remaining parts among the plurality of parts will be used for manual performance.

A semiconductor memory may be used in place of the floppy disk memory.

The sound source parameters change depending on the tone synthesis method.

In the subtraction method, all you need to do is send the filter transfer characteristics and the sound source waveform.
PG), the residual waveform and prediction coefficient, and the sine wave synthesis,
In waveform synthesis, data on the spectral level and phase angle of each harmonic component, the sample value of each waveform, the synthesis weighting coefficient of the waveform, and the frequency, level, and phase angle of the modulated wave and the modulated wave become sound source parameters, respectively.

The sound source parameters are normally closely linked to the synthesis method of the musical tone synthesizer 4o. However, it is possible to change the parameters to a format suitable for another synthesis method. therefore.

When parameters are sent that are not in a format that matches the synthesis method of the musical tone synthesizer 40, conversion may be performed. This conversion can also be performed by the microprocessor 33 and a conversion procedure program.

A receiving device may be provided in place of the above-mentioned line connection device, and the transmitted music information may be received and played.

Effects of the Invention As described above, in the present invention, various types of music information are prepared in the center, and this information is transmitted and used, so that the music information can be compressed and the line cost can be reduced. Also, since the music is sent in a format almost equivalent to a musical score, it is possible to make partial changes to the music. For example, changing the tempo, pitch, t, or part of bar F. These can be used for musical training and education.

Since the sound source parameters are immediately transmitted, it is possible to use a sound source that matches the song, and it is possible to transmit and play music that matches the atmosphere of the program.
