Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to MIDI (Musical
Instrument Digital Interface) MI that selects music from a storage medium that stores data and drives an electronic musical instrument
The present invention relates to a music selection device of an audio device using a DI sound source.

[0002]

2. Description of the Related Art Recently, MID has been used as a sound source device for electronic musical instruments.
An acoustic device using an I sound source is known. In this device, musical score information such as pitch, length, tone color, and intensity of each sound is stored as MIDI data in a storage medium such as a CD-ROM for each music. And the performance of the song is this MI
This is performed by outputting each sound with an instructed timbre, pitch, length, and intensity based on DI data.
In the conventional CD, the analog sound waves of the actually played song are sampled at predetermined time intervals and digitized, and these numerical values are stored, so that the data amount becomes enormous and the playing time for one CD is increased. Is about one hour, so the number of songs that can be stored is only a dozen at most. Therefore, in the case of this CD, there is no particular complication regarding selection of music.

[0003]

However, in the case of a MIDI sound source, the amount of control data is stored as control data for creating the constituent sounds of a song, so the amount of control data is the number of parts and the number of notes per song. It is just the product of the number of controls required to make one sound. Therefore, the number of songs that can be stored in one CD-ROM is extremely large, and tens of thousands of songs can be recorded as one song is 3 minutes. If the number of songs is extremely large, it becomes extremely difficult to select a song to listen to.

In particular, when an audio device using a MIDI sound source is used as a car audio system, it is essential to be able to easily select music while driving. The present invention has been made to solve the above-mentioned problems.
It is to facilitate music selection in an audio device using an I sound source and improve its operability. In particular, it aims to increase the frequency of music selection according to the listener's taste of music.

SUMMARY OF THE INVENTION According to the present invention, a desired song is selected from a storage medium in which MIDI data storing a tone color, pitch, sounding time, etc. for controlling an electronic musical instrument is defined for each song. The present invention relates to a music selecting device in an audio device that uses a MIDI sound source to play a music by controlling an electronic musical instrument based on MIDI data of the selected music. Claim 1
According to the invention of claim 1, when a song is played according to the MIDI data of the storage medium or when the song name is displayed, priority input means for inputting the priority of the song selection depending on the degree to which the user desires to hear the song again. Based on the priority storage means for storing the priority input by the priority input means for each song of MIDI data, and the priority stored by the priority storage means, the higher the priority, the more frequently the song is selected. As many as possible, a music selection control means for controlling music selection from the storage medium is provided.

According to a second aspect of the present invention, the music selection control means sets the music selection target only to the music having the priority higher than the predetermined value, and the higher the priority, the higher the frequency of the music selection.

According to a third aspect of the invention, the music selection control means selects only music having a priority of a predetermined value or more, and selects music within a music group having a commanded priority. .

ACTION AND EFFECT OF THE INVENTION The listener does not want to listen to the played song or the displayed song title in the future frequently, but not to want to listen at all. Have an impression about the desire to listen again, such as not wanting to listen. Therefore, the listener inputs a song selection priority for this song in accordance with the degree of desired relisting. The song selection priority is stored for each song stored in the storage medium.
Then, from the next song selection, that song will be selected at a frequency according to the song selection priority.

In this way, the listener can set the degree to which the listener wishes to listen again to the song only by setting the song selection priority with the push button switch or the like. As a result, only the music desired by the listener is played with a frequency according to the degree, and the music selection operation becomes extremely easy. Further, in the invention of claim 3, by designating a music group classified by priority, it becomes possible to select music within the group, so that the operability for music selection is further improved.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below based on specific embodiments. FIG. 1 is a block diagram showing an audio device using a MIDI sound source according to a specific embodiment of the present invention. MIDI data is recorded on the CD-ROM 20 for each song. The CD drive 11 is the CD-R
The MIDI data of the music instructed by the OM 20 is sequentially read and output to the MIDI sound source device 14. The MIDI sound source device 14 generates a sound waveform of a specified tone color, pitch, length, and intensity based on the input MIDI data, and outputs an electric signal of the sound waveform to the speaker 15. As a result, the selected song is played.

Further, a display device / operation panel 12 is connected to the CD drive device 11, and the display device / operation panel 12 displays a selected music title, music number, performance elapsed time, etc. A setting button 122 for setting the priority and an end button 123 for interrupting the performance of the music are provided. Furthermore, the CPU 1 that sets priority and controls music selection
0 is a CD drive device 11, a display / operation panel 12,
RAM 13 is connected. The RAM 13 stores the set priority for each song.

FIG. 2 is a flow chart showing a music selection procedure by the CPU 10. The music selection procedure will be described below with reference to FIG. In the present embodiment, the priority indicates the degree of relisting desired, and has three levels of 1, 2, and 3.
1 means "I do not want to listen again", and 2 means
The term "normal" does not mean that I do not completely refuse, but I do not want to listen frequently, and "3" means the degree that "I like to listen well". The CD-ROM 20 has the number of songs N
4 are stored, and the priority for each song number is shown in FIG. 4 and FIG.
As shown in FIG. 5, in the RAM 13, the music piece number is associated with the memory address, and the set priority (rank) of the music piece number is stored updatable at the corresponding address.
Incidentally, the initial value of the priority is preset to 2 which represents a normal level.

In step 100, the first music piece number variable a for selecting a music piece is set to an initial value of 1, and the second music piece number variable b is set to an integer of an initial value (N / 2 + 0.5). Therefore, the initial value of the second music number variable b is the center music number when N is an odd number, and the first music number of the second half when the total number of songs is divided into the first half and the second half when N is an even number. The first song number variable a is the priority (“rank”)
Also, in the drawing, it is displayed by rank. ) Is for selecting songs 2 and 3,
The song number variable b is for selecting only songs having a priority of 3. By the first music piece number variable a and the second music piece number variable b, the music selection operation is alternately performed with the number of music pieces separated by about N / 2. Therefore, during the entire number N of songs, the song of priority 1 is not selected at all, and the song of priority 2 is selected only by the first song number variable a. The songs selected and having the priority of 3 are selected by the first song number variable a and the second song number variable b, and thus are selected twice during one cycle. Therefore, the music of priority 3 is selected twice as frequently as the music of priority 2.

At step 102, the priority of the music specified by the first music selection variable a is determined based on the priority information stored in the RAM 13. If the priority is not 1, that is, the priority is 2 or 3, step 10
In step 4, the performance processing of the music piece specified by the first music selection variable a is executed. If the priority of the music identified by the first music selection variable a in step 102 is 1, this music is not selected.

The performance process of step 104 is executed according to the process procedure of FIG. In step 200, the music corresponding to the music number of the first music number variable a is the CD-ROM.
20 is searched, and the song number and song name are displayed on the display 121. Next, at step 202, the CD drive device 11 is instructed to start playing the music number of the first music number variable a. The CD drive device 11 sends this performance start command to C
When input from the PU 10, the MIDI data of the song is sequentially output to the MIDI sound source device 14. As a result, the selected song is played.

The CPU 10 at step 202
After outputting the performance start command, it is determined in step 204 whether the setting button 122 has been pressed. When the setting button 122 is pressed, the state of the setting button 122 is read in step 206, and the priority is set for the song according to the state. This priority is RAM13
It is stored in correspondence with the song number. The setting button 12
The "x" button of 2 means the priority 1 which is not desired to hear twice, and the "○" button of the setting button 122 means the priority 3 which is desired to hear well.

Through this processing, the listener can display the display 121
The priority of the song can be set immediately after the song number and the song name are displayed in until the performance of the song is completed. In step 204, the setting button 122
If it is determined that is not pressed, step 2
At 08, it is determined whether or not the end button 123 has been pressed. If it is determined that the end button 123 has been pressed, in step 210, an instruction to suspend the performance of the song is output to the CD drive device 11. When the CD drive device 11 inputs the interruption command, it stops the output of MIDI data and interrupts the performance of the music. Then, the performance control program for this song ends. Also, step 208
If it is determined that the end button 123 has not been pressed, the process proceeds to step 212 and the CD drive device 11
The output signal from is input to determine whether or not the performance of the song has ended. Even when the performance of that song ends,
This music performance control program ends. Also, step 2
When it is determined in 12 that the performance of the music has not ended, the process returns to step 204 and the above-described processing is repeatedly executed.

After all, while the music is being played, the CPU 10
Will repeatedly execute the processing of steps 204 to 212. Then, during that time, if the priority is set, the priority already set in the RAM 13 is updated to the new set value. Also, the listener sees the display of the song number and song name and immediately sets the setting button,
By pressing the end button and, only the priority can be set without the music being played. By repeating this, the listener can first select only the songs he or she wants to hear. Also, after the song has been played, you can listen to the song, set the priority in the middle of the performance, and press the end button to update the priority without listening to the song until the end. It can be performed.

In this way, when the performance control of the music in step 104 of FIG. 2 is completed, the process proceeds to step 106, in which the priority of the music specified by the second music number variable b is good and the priority is 3 It is determined whether or not. Priority 3
If so, the performance processing program of FIG. 3 is started for the music, and the performance control of the music is executed as described above. If the priority is not 3, the performance control program of step 108 is not executed and step 110 is executed.
Move to At step 110, the first song number variable a and the second song number variable b are added and updated by 1. Then, in step 112, it is judged whether or not the first music number variable a exceeds the final music number N, and if it exceeds, step 11
At 4, the first music number variable a is set to 1 of the first music number. Similarly, for the second song number variable b, in step 116,
It is determined whether the second music number variable b exceeds the final music number N, and if it exceeds, the second music number variable b is determined in step 118.
Is set to 1 of the first song number. Then, step 10
Returning to step 2, the music selection process for the next music number is executed.

By the above processing, a song of priority 3 is selected twice and a song of priority 2 is 1 during the entire number N of songs.
The song is selected once, and the song of priority 1 is never selected. In this way, it is possible to control the frequency of music selection according to the priority.

Next, the manner of selecting music will be described with reference to FIGS. In FIGS. 4 and 5, for simplicity, the total number N of songs is 9, and the priority is represented by ranks in the table. The horizontal axis of the figure represents the number of times the performance control program is executed in step 104 or step 108, that is, the number of times of performance. The black symbols indicate the song numbers actually selected, and the wide symbols indicate the song numbers selected by the first song number variable a. Further, the outline symbols indicate the music numbers indicated by other music number variables in the selected music state.

As described above, in the case of FIG. 4, the number of pieces of music with priority 1 is 1, the number of pieces of music with priority 2 is 6, and the number of pieces of music with priority 3 is 2, but the number of music number variable goes round. In the meantime, the number of times the priority 1 song is played is 0, the number of the priority 2 song is 6, the number of the priority 3 song is 4, and the priority 3 song is played twice as often. I understand that. Further, in the case of FIG. 5, the number of songs with priority 1 is 1, the number of songs with priority 2 is 3, and the number of songs with priority 3 is 5. It can be seen that the number of times of playing the song of 1 is 0, the number of playing of the song of priority 2 is 3, the number of playing of the song of priority 3 is 10, and the song of priority 3 is played twice as frequently. .

In the above embodiment, the priority information is CD-RO.
Although it is stored in the RAM 13 which is a medium different from the M20, when the MIDI data is stored in a writable medium such as a magneto-optical disk or a magnetic disk,
The priority information may be stored on this storage medium. In addition, all the songs of the CD-ROM 20 or only the selected songs are loaded into the CD drive device 11 such as a RAM or a magnetic disk.
Alternatively, the priority may be set for the music stored in this writable storage device by copying it to the writable storage device.

Although the priority is set to three levels, the number of levels is not limited. The tune number variable is increased one by one, but it may be changed irregularly. As a method of changing the music selection frequency according to priority, songs are divided into groups according to priority, each group is selected at a frequency according to priority, and songs are sequentially and arbitrarily selected in the selected group. Alternatively, the songs may be selected randomly. For example, a song group with a priority of 3 is selected twice in three times, and a song group with a priority of 2 is 3
You may make it select once at a time. In addition, a button switch that can specify the music selection group classified by priority,
In the priority song group selected by this switch,
The songs may be played sequentially, randomly, or randomly.
