Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a center-type automatic performance method in which a terminal accesses a center system via a communication network and automatically plays a piece of music.

[Conventional technology]

Traditionally, computers were used as standalone,
Performance information was stored in a floppy disk device, etc., and when a song title or song number was input from a keyboard, the corresponding performance information was read out from the floppy disk device and played.

[Problems to be solved by the invention] In such a stand-alone system,
When adding new songs or arranging them, do you do it individually for each system?
It would be necessary to set up a place to create and sell floppy disks for performance information. Also, Flotsupi
If we set up a place to create and sell discs, the capacity of the floppy disks would require that they be created for each genre, and the purchaser would have to create multiple floppy disks, including songs they don't need. You will have to buy it.

[Means for solving problems]

Means for solving the above problems will be explained using FIG. 1 corresponding to the embodiment.

In FIG. 1, 1 is a center system, 101
consists of multiple sets of note (pitch) number (N), step (note length) number (S), gate (performance length) number (G), and velocity (volume) number (V) that represent one musical note. Melody pattern information for main melody and countermelody songs, 1
02 is accompaniment designation information for each song consisting of an accompaniment type designation number specified for each measure of the song, 103 is preset information for the song consisting of rhythm type numbers, etc., 2 is the communication network, 3 is the terminal, and 301 is the rhythm. Code conversion information for converting the type number to N for accompaniment,
302 is accompaniment pattern information consisting of S, G, and V.
(a), 303 is accompaniment pattern information (b) consisting of N, S, G, and V.

In the present invention, after the terminal 3 connects to the center system 1 via the communication network 2, when the terminal 3 transfers the song number to the center system 1, the center system 1 receives the melody pattern information 101 and accompaniment information corresponding to the song number. 102 and preset information 103 are taken out and returned to the terminal 3, and the terminal 3 extracts accompaniment pattern information (a) 302 and accompaniment pattern corresponding to the accompaniment specification information 102.
(b) Take out 303 and write preset information 1.
03 as a key, chord conversion is performed using the chord conversion information 301 to obtain N for the accompaniment pattern information (a) 302, and the melody pattern information 101 necessary for the performance information, the accompaniment pattern information (a) 302, and the accompaniment pattern information ( b) By organizing 303, the above problem is solved.

[Effect]

The melody pattern information 101, accompaniment specification information 102, and preset information 103 corresponding to each song stored in the center system 1 are all necessary each time a song is added, but the code conversion information stored in the terminal 3 is 301 and accompaniment pattern information (a) 302
The accompaniment pattern information (b) 303 is common to all songs and is fixed information. Therefore, when adding music, only the center system 1 needs to be changed, and the terminal 1 does not need to be changed at all. Further, information regarding the accompaniment transferred from the center system 1 to the terminal 3 is accompaniment specification information 102;
Since this is specified in units of one measure, the data to be transferred will be extremely compressed.

FIG. 8 is a diagram showing the contents and structure of a performance information table, and 508 is a performance information table.The operation of this embodiment will be explained. The terminal 3 is connected to the center system 1 via the communication network 2 according to a commonly known procedure, so that information can be transmitted and received between the terminal 3 and the center system 1. When a song title or song number (MN) is specified from the keyboard 33, the terminal control device 31 transfers this to the center control device 11 via the communication network 2. The center control device 11 accesses the center storage device 12, retrieves basic performance information corresponding to the designated song number (MN), and sends it back to the terminal control device 31 via the communication network 2. The terminal control device 31 is the center control device 1
Based on the basic performance information sent from 1, the terminal storage device 32 is accessed to create performance information. This performance information is input to the synthesizer 35, which is commonly known as MIND (Musical Instrument
shall take the form of a Digital Interface) signal. When the synthesizer 35 receives the performance information, it converts it into an analog signal of music and outputs it. This output is amplified by an amplifier 36 and converted into audio by a speaker 37.

Next, from the center control device 11 to the terminal control device 3
The basic performance information to be transferred to No. 1 will be explained in detail with reference to FIG.

The basic performance information is stored in the center storage device 12 in the form of a basic performance information table 400. The performance basic information table 400 is indexed by the song number (MN) and the performance basic information is extracted. Third
The figure shows a case where MN=3, in which case performance information #3 is extracted. Basic performance information 401
As shown in Figure 3, it consists of preset information, melody pattern information, counter-melody pattern information, accompaniment specification information (chord name information, rhythm accompaniment specification information, bass accompaniment specification information, chord accompaniment specification information), and lighting control information. However, the content of these songs differs depending on the song. The lighting control information is for controlling the lighting equipment 39 of the terminal 3, and is not information necessary for the performance. Basic performance information 40
1 has one bar as a basic unit and is composed of information for the number of bars in the song. Preset information includes rhythm type (waltz, march,...) designation number (R), standard tempo designation number (T), and genre (chienson, pops,...)
It consists of a designated number (J) and an expression type (cute, cheerful,...) and a designated number (E), and is set for each measure. Main melody pattern information is melody information and corresponds to MIDI signals, including note (pitch) number (N), step (note length) number (S), gate (play length) number (G), and pelocity (volume). ) number (V) as one set, and 16 sets can be set in one measure. The counter melody pattern information is counter melody information, but has the same format as the main melody pattern information. The chord name information includes the root note number (K) representing the basic note and the chord type (Maj, min,...)
With number (C) as one set, four sets can be set in one measure. Rhythm accompaniment designation information, bass accompaniment designation information, and chord accompaniment designation information each consist of a rhythm instrument designation number (Z), a bass accompaniment designation number (B), and a chord accompaniment designation number (G), each of which is set once per measure.
The lighting control information can be set in 16 sets per measure, with a color number (CL) and a brightness number (LK) as one set.

Next, a procedure will be described in which the terminal control device 31 receives basic performance information from the center control device 11 via the communication network 2, and creates performance information based on the information using a pattern library in the terminal storage device 32.

The terminal control device 3 reads the pattern library 500 from the terminal storage device 32. The pattern library 500 is indexed using the rhythm type number (R) included in the preset information in the basic performance information sent from the center control device 11, and pattern information is extracted. FIG. 4 shows a case where pattern information #3 is extracted with R=3. The pattern information is 50 in Figure 4.
1, it consists of a chord conversion table, a base pattern table, a chord pattern table, and a rhythm pattern table. As for the chord conversion table, as shown at 502 in FIG. 5, the chord information is obtained by indexing the chord type number (C) in the received performance basic information. The code information is composed of a basic form, a first inversion, and a second inversion. The chord information is indexed by the root note (K) and one of the forms is obtained. The root note (K) can be changed according to the user's preference by inputting an increment/decrement from the keyboard 33, and is created from this value and the received root note (K). In Figure 5, C
=3, code information #3 is extracted, K=60=63
A case is shown in which the second inversion form is extracted by indexing with (root note of reception) - 3 (change amount)). For each type of chord information, node variations corresponding to the first to fourth notes are stored. The note value is relative to the root note. Add the root note and node barille to obtain the note number (N) for each of the 1st to 4th notes. These node numbers (N) are used as note numbers of the first to fourth notes in the bass pattern and chord pattern. The bass pattern table is indexed using the bass accompaniment designation number (B) as shown in FIG. 6 to obtain bass pattern information. The bass pattern information consists of the 1st to 4th notes, and 16 pairs of step numbers (S), gate numbers (G), and velocity numbers (V) are stored for each measure. has been done. By adding the note number obtained from the chord conversion table to this, base pattern information of performance information is created and stored in the performance information table as shown in FIG. Chord pattern information and bass pattern information of performance information are created by the same procedure. This is also as shown in FIG. As shown in FIG. 7, the rhythm pattern table is indexed by the received rhythm pattern number (Z) to obtain rhythm pattern information. FIG. 7 shows an example in which rhythm pattern information #2 is obtained by indexing with Z=2. Rhythm pattern information is stored for two measures each, consisting of 16 pairs of note numbers (N), step numbers (S), gate numbers (G), and velocity numbers (V), corresponding to each of multiple rhythm instruments. has been done. This rhythm pattern information is also stored in the performance information table shown in FIG. Furthermore, the received main melody pattern information and counter melody pattern information are stored in this performance information table, thereby completing the creation of the performance information table. The terminal control device 31 sequentially reads out this performance information table from top to bottom and outputs it as a MIDI signal to the synthesizer 35 for performance.

Further, the received lighting control information is sent to the lighting control circuit 38 by the terminal control device 31 according to the content.
to control the color and brightness of the lighting fixture 39.

〔Effect of the invention〕

As explained above, the center storage device 12 stores preset information, main melody pattern information, counter melody pattern information, and accompaniment designation information (chord name information,
Rhythm accompaniment specification information, bass accompaniment specification information, chord accompaniment specification information) and additional lighting control information are stored corresponding to songs, and these pieces of information differ for each song. On the other hand, the terminal storage device 31
stores fixed pattern information common to all songs. The terminal 3 creates accompaniment pattern information from preset information and accompaniment designation information on the center side and fixed pattern information on the terminal side. Since such information management and creation procedures are in place, when adding a new song, only the center storage device 12 needs to be changed, and the terminal storage device 32 does not need to be changed at all.

Furthermore, since the accompaniment designation information stored in the center storage device 12 is not performance pattern information, the amount of information transferred to the terminal 3 can thereby be reduced.
