Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a storage device in which music data such as musical note lengths and musical scales, and control data for controlling the start of music performance, performance status, etc. are recorded. , relates to a music performance device equipped with a music performance control device.

Structure of conventional examples and their problems Traditionally, music has been recorded on magnetic tape, records, etc., and instead of selecting the desired song from a list of songs with titles, it is necessary to memorize the song. There are times when a song is actually performed by a performer, such as when the song has been played but has forgotten the title. To meet such demands, some tape recorders have a convenient function called an "intro performance function." This detects the part between songs on the magnetic tape in high-speed fast-forward mode, detects the gap between songs, switches to playback mode, plays the beginning of the song (often abbreviated as intro) for a few seconds, and then returns to high-speed fast-forward mode. The operation of switching to [I old 14] and detecting the next one is repeated. Also, record players and the like having similar functions have been proposed.

However, the biggest drawback of this conventional configuration is that the intros for each side are so different within a few seconds that it is often impossible to distinguish between songs.

That is, the beginning of each side is usually an introductory part before the lyrics appear, and the playing time of this introductory part varies. On the other hand, considering the original function of song selection, which plays only the intro of each side for a few seconds one after another,
It is not possible to set the intro playback time to as long as 10 seconds so that the lyrics can be heard. Therefore, the user has to judge the song only by the prelude part without lyrics, and in reality, this judgment is very difficult.

In a tape recorder with the above-mentioned "intro performance function", it takes several seconds to over 10 seconds to detect the next song interval, even if it is a high-speed fast forward, and during that time there is no sound or a cue sound playing state. However, it felt good to the user and there was no discernible impression. Furthermore, even when playing a song, the running direction of the magnetic tape is in order.
3 Thinking about it in three parts, 1/3 after p, first
It is extremely difficult to automatically carry out procedures such as raising the 7/3 part and then raising the previous 1/3 part, and it is also functionally insufficient.

OBJECTS OF THE INVENTION It is an object of the present invention to eliminate the above-mentioned conventional drawbacks, and to provide a musical performance device.

Structure of the Invention The present invention comprises a storage means that stores music data and performance control data, and in particular stores the beginning part of the music data so that the prelude part and the melody part can be distinguished, and a command signal from the operating means is inputted. and a control means for driving the storage means and a sound source, wherein the control means sequentially reads out the beginning part of each side of the song data from the storage means and detects an introductory part and a part of the melody of the beginning part. Based on the beginning part detection means and the output of this beginning part detection means,
It has a performance control means that reads music data and performance control data for a part of the melody from the storage means, generates a control output to the sound source, and causes only the part of the melody at the beginning of each side to be played sequentially and continuously. be.

This display device 6 displays the number of the song being inputted by operation, the number 1111 being played after the start of the performance, etc. using a numerical keypad or the like. 7 is a storage device that stores data (song data) related to the so-called song itself, such as pitches and note lengths of melodies and accompaniment chords, rhythm timing, etc., and unique addresses of the song data between each. Information particularly necessary for the performance of the music, such as the music numbers and genre identification codes added between each piece, and performance control data for controlling the so-called performance status are stored in a format to be described later. The performance control data includes bar delimiter codes, prelude and melody delimiter codes, and the like.

8 is an 1lflJ control device that controls the operation of this device.

This control device 8 includes a song number storage section 82L9 that stores the song number inputted from the operating device 5; a comparison section sb that compares and confirms the content of the song number storage section 82L with the song number read out from the storage device 7; A counter section sc that counts the measures or notes to be played, a performance speed control section 8 (1) that controls the timing of sending data to the sound source section, and a drive section that reads the storage device 7 and receives input data from the operating device 5. It consists of a display device 6, an input/output section that sends data to a sound source section 9 (to be described later), an operation control section for the sound source section 9, etc. In this embodiment, the control device 8 is constituted by a microcomputer and has a memory. The device 7 is configured with a semiconductor ROM.Depending on the limitations such as storage capacity, the control r41S8
In addition, it is also possible to configure a single microcomputer including the digital code converter and the storage device 7, which are part of the operating device 62 and display device 6, or to include two or three of these components. It is also possible to configure it with a microcomputer.

The sound source section 9 is a melody sound source and an accompaniment sound source, respectively, depending on the song data read out from the storage device 7.

A music signal for each rhythm sound source is generated, and a speaker 4 is driven through an amplifier 1° to play music.

FIG. 4 is a flowchart showing the processing in the control device 8.

FIG. 5 is a flowchart showing the performance control process for the intro performance in more detail.

The operations will be explained below according to these flowcharts.

For normal performance, step 302. Step 303
If you input the desired song number using the operation key 1a and then press the normal play key 1c, the process moves to step 309, where the song data of the specified song number is read out from the storage device 7, and the sound source is output via the control device 8. The data is sent to section 9, and the music of the desired song number is played.

Further, if a genre is specified in step 3o5 by the genre key 16, the genre data included in the performance control data read from the storage device 7 and the specified genre data (for example, "1" in the case of a popular song, The comparator 8b compares the nursery rhymes (for example, ``2''), and only the songs of the same genre as the designated genre are sequentially played.

When you want to play only the beginning of a song, that is, when you want to search for a desired song by intro performance, first specify whether you want to play the next measure using the number key 1U and the measure specification key 1gK. For example, if the user presses the number key "4" all the way and then presses the measure designation key, the process advances to step 306 and designates that only the first four measures of the song be played sequentially. After specifying the measure to be played, press the intro play key 1d to proceed to step 308, the performance control routine for the intro performance.
The process flow is as shown in the figure. Details of the operation at this time will be described later.

The performance speed control section 8d stores the number of internal clock cycles for one unit (for example, a 16th note), and the control section 8 obtains the timing for sending data to the sound source section based on this value. For example, if this value is "32" for normal performance, setting it to "24" for intro performance will change the performance speed to 4/3 (32 ÷ 2).
4) Can be doubled and listened to faster without compromising intelligibility. Of course, if emphasis is placed on the standard performance speed, this step 401 may be omitted.

The song data is stored in the storage device 7 in a format as shown in FIG. Start address A of this song data,
1, data indicating which genre the song belongs to, data for initializing the sound source section 9, etc. are recorded. From address A2 (d), the song data for the prelude is recorded, and in the case of a normal performance, data for the end of the performance is sent to the sound source section 9 based on this data, and the music is played.In the case of an intro performance, The prelude is not played, and in step 403, the prelude end chord is found. The counter that counts the number is reset, and the sound source section 9 is driven based on the data of the first measure of the melody recorded from the next address A11, and one measure is played in step 406. Measures are separated at address AI2. If the play stop key 1b is not pressed in step 407, the process goes to step 408, counts up the counter, returns to step 405, and compares whether the specified number of measures have been played. If so, repeat the same routine and continue playing.For example, if it is specified to play 4 measures, address A12.A14.Ale
, Als, and the bar separation, the counter value counts up to "4", and since the specified number of bars have been played, the process proceeds to step 409 where a performance stop signal is output. Thereafter, in step 410, the song number data stored in the song number storage section 8a is updated to the next song number, and the intro performance of the song is performed in the same manner as in step 402 [returning]. When it is determined in step 402 that all the built-in songs have been played, the process returns to main routine step 302 and waits for the next key.

When specifying or updating the song number, the song number storage section 8a
By transmitting the data to the display device 6, the user can know on the display device 2 which song number is currently being played.

If you find the song you want while playing the intro Step 4
Step 30 by pressing the performance stop key 1b at step 07.
7 to pause the performance and then press the normal play key 10. Since the song number is stored in the song number storage section Ba, the desired song including the prelude will be played normally ( Step 3o2. Step 3o9).

In the above example, the number of measures was specified to specify the length of the intro performance (part of the melody).
You can also specify the number of notes.

In this case, the same configuration can be used if the counter section 8C is counted up every time note information is sent to the sound source section 9 instead of every bar. Note that it is also possible to fix the number of measures to 4 measures, 8 measures, etc. without providing a measure specification gee.

1. If you want to play the beginning of the song for a certain period of time, install a timer part aefc instead of the counter section 8C as shown in Figure 6, and input the digits from the timer after a certain period of time after the start of playing The performance can be stopped by an overflow signal, etc., and the intro performance of the next song can be started.

Furthermore, up to the ox of the structure shown in Fig. 3, instead of the processing procedure shown in Fig. 5, the processing procedure shown in Fig. 8 is used to play at a slightly faster speed than the actual performance speed without omitting the prelude part, and part of the melody is It is also possible to perform the intro for a specified number of measures at the actual performance speed, which is effective when 1) you want to hear the intro from the '111 section.

The processing procedure will be explained using the flowchart of FIG. 8, focusing on the differences from the flowchart of FIG. 6. In order to speed up the performance speed in step 702, the performance speed control section 8
Change the speed data set in dVC to make it play a little faster.

Then, the process proceeds to step 703, where the storage device γ shown in FIG.
The data is retrieved from address A2 of the song data recorded in , and the prelude part is played. At the prelude end code of address AIO, this step is exited, and in step 704, the playing speed: Ifll ni 1 part 8 B is restored to its original speed data, and hereafter, a part of the melody is specified as above at the actual playing speed. Play only the selected measures. Try below: @
The processing procedure is the same as described above.

Moreover, if a genre is specified in advance using the genre key 1e, it becomes possible to play the intro of only songs of that genre, thereby shortening the time it takes to search for the desired song.

As described above, according to this embodiment, it is possible to realize a music performance device that has a very convenient music selection means that can sequentially and continuously play only a part of the melody at the beginning of each side. The greater the number of songs stored, the greater the effect.

Furthermore, this device has a wide range of possibilities for development, such as by selecting the song to be played using random numbers, or by having the questioner specify the song, it is possible to play a game in which the player guesses the name of the song by listening only to the beginning of the song.

Effects of the Invention The present invention is equipped with a storage means for storing musical piece data by distinguishing between a prelude part and a melody part, and a control means for controlling music performance based on this music data. By sequentially playing only part of the melody excluding the prelude, when selecting a desired song from among a large number of songs, there is no need for a list of songs, and even if you do not know the name of the song, you can compare part of the melody. I can easily select songs because I remember them well. In particular, with the configuration of the present invention, only a part of the melody excluding the rY1 part of each side can be played, and the user can always play the lyrics of part of the melody, regardless of the length of the prelude part. It is possible to identify a song by listening to it, which is very convenient. Furthermore, since the present invention sequentially reads out and plays the beginning part of the song data stored in the storage means, a part of the melody of each side is played continuously one after another, and the prelude part of each side is played in sequence. Compared to the system in which there is a blank time between the beginning of the next song and the beginning of the next song, it is more efficient and reduces the time it takes to select a song. It is something that can eliminate pleasure.

Further, when the music data of a large number of songs are stored in the storage means, only a part of the melody at the beginning can be successively played from any part of the dog music data part. For example, by attaching performance control data categorized by genre to a large number of stored songs, you can sequentially select only songs of a specified genre and play only part of the melody at the beginning, making song selection even easier. This makes it easier.

By providing the control means with a dividing means for the number of measures or the number of notes, or a timer means, the length of the part of the melody to be played can be specified by the number of measures or notes, or set to a fixed time, and the user can request It becomes possible to perform music selection operations according to the user's needs.

Furthermore, by providing a performance speed control means in the control means, it is possible to perform a part of the melody at a speed slightly faster than the actual performance speed, and further shorten the music selection time. Furthermore, if the introductory part of each side is played at a faster speed without omitting it, and a part of the melody is played at the actual speed, it is very effective when searching for a song with a distinctive introductory part.

As described above, according to the present invention, it is possible to realize a music playing device that can play the beginning portions of each side sequentially and continuously and has excellent operability when selecting songs.
