In such a karaoke apparatus and a communication karaoke system, performance information of karaoke music is stored in Musical format.
Instrument Digital Inter
In many cases, performance data such as pitch information at the time of performance of a musical piece and tempo information as a performance speed are recorded in the MIDI data.

Conventionally, a function has been provided in which a user can arbitrarily change the tempo value (performance speed) of a performance during the performance of karaoke music. There has been a music performance device (for example, see Japanese Utility Model Registration No. 30000299) that allows a user to play or select a tempo value adjusted during a previous performance without returning the value.

[0005]

However, in the above-described music playing apparatus, if the tempo value of the karaoke music is played back with the tempo value adjusted during the previous performance without returning to the initial value, the tempo value becomes the next value. Often, it becomes difficult for the user to sing, and the next user must change the tempo during the performance, the operation of tempo adjustment becomes complicated, and the adjustment must be performed frequently,
I couldn't concentrate on singing, and there was a problem that the fun was halved.

[0006] Even if the tempo value of the karaoke music is returned to the initial value every time the performance is performed, if the initial value does not become a tempo that is easy for many users to sing, each user frequently performs during the performance. In this case, the tempo value was changed, and it was not possible to concentrate on singing, and there was a problem that the enjoyment was reduced by half.

In the above-described music performance apparatus, the pitch value (key) of the karaoke music can be switched in several steps in the vertical direction with respect to the key defined by the note number of the MIDI data in several steps. The information on the relative level of the key is included in the information file in the music data. This key has the same problem as the tempo described above.

Therefore, each user carries a memory card storing performance conditions such as tempo values and keys which are most easily sung by the user. When using a music performance device, the user inserts the memory card and stores the memory card in the memory card. The karaoke music may be played based on the set performance conditions, but it is inconvenient because the cost of the music performance device increases and the user cannot use the music without bringing a memory card.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and allows a large number of users to automatically play music under performance conditions that are easy to sing based on the state of adjustment of the tempo and key performance conditions for the performance music. The purpose is to be.

It consists of data such as tempo value, sound generation event, waiting time, sound stop event, etc., and the waiting time is represented by a positive positive number n.
This is a value obtained by multiplying the unit waiting time (unit: ms) calculated from the time base and the tempo in the header by n, and the value is the actual waiting time.

The time base is the resolution of a quarter note (the number of quarter notes decomposed), and is generally "48" or "96".
Is used. Increasing the tempo value while keeping the time base constant reduces the unit waiting time. Therefore, the sounding duration of the sound generated by the sounding event is shortened. Conversely, when the tempo value is reduced, the unit waiting time increases, and the sounding duration of the sound generated by the sounding event increases.

Next, the processing of the communication karaoke system will be described. Remote control 21 in the karaoke device 2
Alternatively, when a music number for selecting karaoke music is input using the operation panel 108, the commander 27 checks whether or not music data corresponding to the music number exists in the hard disk device 109.

Next, a function in which the karaoke apparatus 2 of the communication karaoke system automatically changes the default key level (pitch value) set in the music data of the karaoke music based on the use situation of the key adjustment by the user. explain.

In order to realize this function, the system control section 101 and the like adjust the pitch value of the music piece being played by the performance means for playing the music piece with the default pitch value based on the performance information. Pitch adjusting means for performing, a means for storing the number of times of the performance music, the adjustment value adjusted by the pitch adjusting means, and the number of adjustments, based on the number of performances, the adjustment value, and the number of adjustments stored in the means. When it is determined that the number of times the performance music has been played with a value other than the default pitch value is greater than a predetermined number, and that the pitch value is biased toward one of a higher pitch and a lower pitch than the default pitch value. The function of means for changing the default pitch value of the musical piece to the pitch value at the center of the bias is performed.

First, the remote controller 21 of the karaoke apparatus 2
Alternatively, the operation panel 108 is provided with a four-step level up key for adjusting the default key level of the karaoke music to a high pitch and a four-step level down key for adjusting the low key to a low pitch. The key level before and during playing can be adjusted step by step.

When the user inputs a song number for selecting karaoke music from the remote controller 21 or the operation panel 108, the system control unit 101 inputs the song number and the pitch history stored in the hard disk device 109. The music number of the file is collated, and it is determined whether or not the input music number exists.

This pitch history file is a file for recording the use status of the pitch adjustment for each karaoke music, and a history of the number of adjustments of the pitch value (key level) at the time of playing each karaoke music in the format shown in FIG. The number of times of performance and the number of times of adjustment are recorded for each tune number of karaoke music (performed music). In the karaoke apparatus 2, the remote controller 21
Alternatively, the number of adjustments is counted for each level of the level up key and the level down key on the operation panel 108, and recorded for each of the four down levels and the four up levels.

If there is a corresponding song number in the pitch history file as a result of the above verification, the number of times of performing the karaoke music of that song number is incremented by 1. If there is no corresponding song number, the song number is additionally registered in the pitch history file. The number of performances is set to 1 and the performance of the karaoke music is started. Then, when the performance of the karaoke music is completed, if the performance is performed at a key level other than the default key level, the number of adjustments of the corresponding key level is incremented by one.

When the pitch history file is updated in this manner, the system control unit 101 checks whether the number of times of performing karaoke music is greater than a predetermined number based on the recorded contents of the pitch history file. Then, it is determined whether or not the number of adjustments of the key level is biased to either the down level or the up level.

Here, if it is determined that there is a bias, and if the number of performances performed at a key level other than the default is equal to or greater than a predetermined number, the degree of bias in the number of key level adjustments, that is, The key level at which the distribution is centered is determined, and the default key level in the information file in the song data of the karaoke music is set to the key level at the center (any one of ± 1, ± 2, ± 3, ± 4) ).

Further, according to the flowchart of FIG.
A process in which the karaoke apparatus 2 automatically changes the default key level set in the song data of the karaoke music based on the usage status will be described.

In this process, it is determined whether or not a music selection has been made in step (indicated by "S" in the figure) 1, and if so, whether or not the music number selected in step 2 exists in the pitch history file. If it is found in the pitch history file, the number of performances of the corresponding song number in the pitch history file is incremented by 1 in step 3, and if not, the song number is newly added to the pitch history file in step 10. Then, the number of performances is set to 1 and the performance of the selected karaoke music is started.

In step 4, it is determined whether or not the performance has ended. If the performance has ended, in step 5, it is determined whether or not the performance has been performed at a key level (pitch value) other than the default. If it is performed, the process returns as it is. If the performance is performed at a key level other than the default, the number of adjustments of the corresponding key level is incremented by one in step 6.

Further, it is determined in step 7 whether or not the number of times of performance of the tune played is greater than a predetermined number. If not, the process returns as it is. It is determined whether or not it is biased in the up direction. If it is not biased, the process returns as it is. If it is biased, it is determined in step 9 whether or not the total number of times of playing at a key level other than the default is not less than a predetermined number. If not, return as it is.

If it is determined in step 9 that the total number of times of playing at a key level other than the default is equal to or more than a predetermined number, the distribution of the number of times of adjusting the key level is checked in step 11, and the distribution of the number of times of adjusting the key level is checked in step 12. Seeking the center,
Replace the default key level in the information file in the song data of the played song with the key level obtained above,
This processing ends.

In the above-mentioned processing, the case where the default value of the key level at the start of the performance is automatically changed has been described. However, this karaoke apparatus is similarly operated based on the number of tempo adjustments by the user of the karaoke apparatus. Then, the center value of the distribution of the adjustment values of the tempo level is automatically changed to the default tempo value at the start of the performance.

As described above, when the preset default key level or tempo level is frequently changed, the karaoke apparatus automatically changes the default value to the key or tempo level value most used in the karaoke apparatus. Karaoke music can be started at the key or tempo level that suits many users' preferences, and the frequency with which the user adjusts the keys and tempo when singing is reduced. Convenience when singing together can be improved. Therefore, the user can concentrate on the singing without worrying about adjusting the key and tempo of the karaoke song when singing, so that the user can enjoy karaoke more.

Next, the karaoke apparatus 2 of the communication karaoke system automatically changes the default key level set in the music data of the karaoke music, based on the user's use of key adjustment for each time period. Will be described.

In order to realize this function, the system control unit 101 or the like stores the number of times of the performance music, the adjustment value adjusted by the pitch adjusting means, and the number of adjustments for each predetermined time period. And the number of times the performance music is played with a value other than the default pitch value becomes greater than a predetermined number based on the number of times of performance, the adjustment value, and the number of adjustments for each time period stored in the means. Means for changing the default pitch value of the music piece performed in that time zone to a pitch value at the center of the bias when it is determined that the pitch is biased toward either the higher pitch or the lower pitch than the default pitch value. Perform the function.

First, a pitch history file is stored in the hard disk device 109 for each predetermined time zone. In this process, a case where the time is divided into two time zones will be described. Time zone 1 from 0:00 pm to 8:00 pm, and time zone 1
The pitch history file created for the karaoke music played on is set as the pitch history file 1. A time zone other than the above-mentioned time is defined as a time zone 2, and a pitch history file created for the karaoke music played in the time zone 2 is defined as a pitch history file 2.

FIG. 8 is a diagram showing an example of the format of the pitch history files 1 and 2. In the format shown in FIG. 6, a setting key level item is newly provided. In the item of the set key level, a key level which is the center of the distribution of the number of adjustments of the key level changed from the default key level is stored.

In the karaoke apparatus 2, when a tune number for selecting a karaoke tune is input from the remote control 21 or the operation panel 108 in the time zone 1, the tune number input by the system control unit 101 and stored in the hard disk drive 109. The music number of the pitch history file 1 is collated.

If there is a music number corresponding to the pitch history file 1 as a result of the collation, the number of times the karaoke music of that music number is played is incremented by one, and if there is no corresponding music number, the pitch history file 1 relates to the music number. A column is added, the number of performances in the column is set to 1, and the performance of the karaoke music is started. Then, when the performance of the karaoke music is completed, if the performance is performed at a key level other than the default, the number of adjustments of the key level is incremented by “1”.

When the pitch history file 1 is updated in this manner, the system control unit 101 checks whether or not the number of times of performing the karaoke music is greater than a predetermined number, and determines whether or not the number of key level adjustments is larger. It is determined whether or not the current level is biased toward either the down level or the up level.

If it is determined that the key level is unbalanced, and if the number of adjustments adjusted to a key level other than the default is equal to or greater than a predetermined number, the degree of bias in the number of key level adjustments, ie, the distribution of the number of adjustments Is determined as to which key level is the center, and the key level at that center (± 1,
Write any one of ± 2, ± 3, ± 4) to the position of the set key level of the corresponding music number in the pitch history file 1. Further, for the time period 2, the pitch history file 2 is updated in the same manner as described above.

Next, the processing when the karaoke apparatus 2 performs the performance by automatically changing the default key level based on the use situation of the key adjustment by the user for each time zone will be further described. First, when a song number for selecting karaoke music is input from the remote control 21 or the operation panel 108 in the time zone 1, the system control unit 101 enters the input song number and the song in the pitch history file 1 stored in the hard disk device 109. Match with number.

If there is a music number corresponding to the pitch history file 1, the setting key level of the music number is checked. If the setting key level is "0", the information file in the music data of the music number is checked. The karaoke music is played at the stored default key level, and if the set key level is not "0", the karaoke music is played at the value written to the set key level, and the key level display on the operation panel 108 (for example, LED) Is displayed).

Similarly, when a song number for selecting karaoke music is input from the remote controller 21 or the operation panel 108 in the time period 2, the system control unit 101 stores the input song number and the hard disk device 109. The music number in the pitch history file 2 is compared.

If there is a music number corresponding to the pitch history file 2, the setting key level of that music number is checked. If the setting key level is "0", the information file in the music data of the music number is checked. The karaoke music is played at the stored default key level. If the set key level is not "0", the karaoke music is played at the value written in the set key level, and the key level display on the operation panel 108 is also switched. In this process, the information file of the music data in the hard disk device 109 is not updated and stored.

Next, the process in which the karaoke apparatus 2 automatically changes the default key level set in the song data of the karaoke tune based on the use status of the key adjustment for each time zone will be further described with reference to the flowchart of FIG. I do.

In this process, it is determined in step (indicated by "S" in the figure) 21 whether or not a music selection has been performed, and if performed, it is determined in step 22 whether time period 1 or 2 is selected. If so, it is determined in step 23 whether or not the music number selected in the pitch history file 1 exists. If the music number is present in the pitch history file 1, the number of times of playing the corresponding music number in the pitch history file 1 is set to "1" in step 24. If not, the music number is newly added to the pitch history file 1 in step 32, the number of times of performance is set to 1, and the routine proceeds to step 25.

At step 25, it is determined whether or not the set key level is "0". If "0", the performance is started at the default key level at step 26; The performance starts at the key level of the level, and proceeds to step 27.

At step 27, it is determined whether or not the performance has been completed. If the performance has been completed, at step 28, it is determined whether or not the performance has been performed at a key level (pitch value) other than the default. If it has been performed, the process returns as it is. If it is performed at a key level other than the default, the number of adjustments of the corresponding key level is set to "1" at step 29.
Only increment.

Further, at step 30, it is determined whether or not the number of times of performance of the tune played is greater than a predetermined number. If not, the process returns as it is. Judgment is made as to whether it is biased in the low pitch) or in the up direction (high pitch). If it is not biased, the process returns as it is. If it is biased, the total number of adjustments at key levels other than the default is not less than a predetermined number in step 34 It is determined whether or not it is, and if it is not equal to or more than the predetermined number, the process returns.

If the total number of times of adjustment at a key level other than the default is equal to or more than a predetermined number, the distribution of the number of times of adjustment of the key level is checked at step 35, and the distribution of the number of times of adjustment of the key level is checked at step 36. The center is obtained, and the obtained key level is written at the position of the set key level in the pitch history file, and this processing ends.

If it is determined in step 22 that the time period is the time period 2, the process proceeds to the time period 2 and the same processing as the above-described steps 23 to 36 is executed using the pitch history file 2 and the process returns.

Further, in the above-described processing, the case where the default value of the key level at the start of the performance is automatically changed every predetermined time period has been described. Based on the number of adjustments, the central value of the distribution of the adjustment values in each time zone is automatically changed to a default tempo value at the start of the performance in each time zone.

As described above, the karaoke apparatus changes the preset key level or tempo level at the start of the performance to the most frequently used key level or tempo for each performance time zone based on the usage status thereafter. Since the level is automatically changed, the performance can be started at the key level or the tempo level that best suits the user in each time zone when the age group of the user is different for each usage time zone.

For example, in the karaoke box, the age group of the user differs depending on the use time zone, and the key and tempo of the same karaoke song change between the time zone frequently used by young people and the time zone used by middle-aged and elderly people. Frequency is different.
Even in such a case, the frequency at which the user changes the key level or the tempo level when singing along with the karaoke song is reduced, and the convenience when singing along with the karaoke song can be improved. Therefore, the user can concentrate on singing without worrying about adjusting the key and the tempo, and can enjoy karaoke more.

Next, a function in which the center apparatus 1 of the communication karaoke system automatically changes the default key level set in the music data of the karaoke music on the basis of the use state of the key adjustment of the karaoke apparatus 2 will be described. .

In order to realize this function, the control device 14 and the like of the center device 1 are configured to store the performance information, distribute the stored performance information,
The number of times the musical piece has been played with a value other than the default pitch value is greater than the predetermined number of times based on the number of times of the musical piece received from the user and the adjustment value and the number of adjustments, and the pitch value is higher than the default pitch value. Alternatively, when it is determined that the musical piece is deviated to one of the low pitches, the function of a means for changing the default pitch value of the musical piece to the central pitch value of the above-mentioned deviation is performed.

The system control unit 101 and the like of the karaoke apparatus 2 play the performance music with the default pitch value based on the performance information distributed from the center apparatus 1, and the performance being performed by the means. The function of the pitch adjusting means for adjusting the pitch value of the tune and the means for transmitting the number of times of the performance music, the adjustment value adjusted by the pitch adjusting means and the number of adjustments to the center device 1 are achieved.

First, the system control unit 1 of the karaoke apparatus 2
01, the pitch history file stored in the hard disk device 109 is periodically checked, and only those whose up-level or down-level adjustment counts are not all “0” are the tune number, the number of plays, and the key level of each key level. The number of adjustments is transmitted to the center device 1 via the communication network 3. Then, after the transmission, the number of times of performance of all songs in the interval history file and the number of times of adjustment of each key level are initialized to "0".

Next, according to the flowchart of FIG.
A process in which the karaoke device 2 transmits information on the key adjustment status by the user to the center device 1 will be described. In this process, it is determined whether or not a predetermined period has elapsed in step 41, and when it has elapsed, initial setting is made to N = 1 in step 42, a pitch history file is read in step 43, and each of the pitch history files is read in step 44. It is determined whether the number of adjustments of the up level or the down level is all "0" for each music number.

If the number of adjustments of the up-level or down-level is not all "0" in the judgment of step 44, the music number, the number of performances and the number of adjustments of each key level are stored as transmission data in the format of a pitch history file. It is stored in the memory 103, and it is determined whether or not all the song numbers have been checked in a step 46. If all the song numbers have not been checked, N is updated to N = N + 1 in a step 49, and the process returns to the step 44 to return to the next song number. Perform a check of

When all the music numbers have been checked in the judgment of step 46, the main memory 103 is checked in step 47.
Is transmitted to the center apparatus 1, and in step 48, the number of performances of all the music numbers in the pitch history file and the number of times of adjustment of each key level are initialized to 0, and this processing ends.

Next, a description will be given of a process in which the center apparatus 1 automatically changes the default key level set in the music data of the karaoke music based on the use state of the key adjustment of the karaoke apparatus 2.

First, the center device 1 is stored in the storage device 13 in advance.
To store the pitch statistical file. This interval statistical file has the same format as the interval history file shown in FIG. 6, and is a file that stores the number of times of performance for each song number and the number of times of adjustment of each key level transmitted from the karaoke apparatus 2 as an accumulated value.

When the center apparatus 1 receives the music number, the number of times of playing, and the number of times of adjustment of each key level from each karaoke apparatus 2, the center apparatus 1 adds the number of times of playing of the same number of music and the number of times of adjusting each key level in the pitch statistical file. And update the file.

Then, the distribution of the number of times of adjustment of each key level is checked for each music number in the pitch statistical file at predetermined intervals, and whether the count value is biased to either the down level or the up level is determined. Determine whether or not.
If there is a bias in this judgment, it is checked whether or not a value obtained by dividing the total value of the number of times of adjustment of each key level of the song number by the number of times of playing of the song number is larger than a predetermined number.

If the above check indicates that the number is larger than the predetermined number,
The degree of bias, that is, the key level at the center of the distribution of the count value is obtained, and the key level is overwritten on the default key level in the music data of the music number to change the default value of the key level.

Thereafter, when a request for song data is received from the karaoke apparatus 2, the updated song data is delivered, and the karaoke apparatus 2 changes the default value based on the key level usage status of many users. Perform karaoke music with song data.

Next, according to the flowchart shown in FIG. 11, the center apparatus 1 automatically changes the performance conditions of the default key level set in the karaoke music piece data based on the use state of the key adjustment on the karaoke apparatus 2 side. Will be described further.

In this processing, it is determined in step 51 whether or not a predetermined period has elapsed.
= 1, the pitch statistical file is read in step 53, and in step 54, it is determined whether or not the number of adjustments of the up level or the down level is biased toward one of the music numbers in the pitch statistical file.

If it is determined in step 54 that the number of adjustments of the up level or the down level is not biased to either direction, the process proceeds to step 59. If the number of adjustments is biased, the total value of the number of adjustments of each key level is determined in step 55. A value M divided by the number of times of performance is obtained, and it is determined in step 56 whether the value M is larger than a predetermined number.

If it is not large, the process proceeds to step 59. If it is large, in step 57, the key level at which the distribution of the number of adjustments of each key level is centered is obtained.
In step 58, the key level at the center is overwritten on the default key level in the information file of the music data of the music number.

Then, it is determined whether or not all the music numbers have been checked in step 59. If all the music numbers have been checked, the process returns to step 51. If not, N = N + 1 is updated in step 62 and the process proceeds to step 54. Return and execute the check for the next song number.

If the predetermined period has not elapsed in step 51, it is determined in step 60 whether the karaoke apparatus has received a song number, the number of plays, and the number of adjustments of each key level. If not, the process returns to step 51. If received, the number of times of performance and the number of times of adjustment of each key level are added to the corresponding value of the same music number in the pitch statistical file in step 61, and the process returns to step 51.

The center apparatus adjusts the number of key level adjustments (count information) received from each karaoke apparatus.
And the result of the calculation is stored as a file in the storage device 13.
, And displayed on the display device 12 or recorded and output on paper by a printing device (printer) not shown.

As described above, the default key level of the music data distributed from the center apparatus 1 to each karaoke apparatus 2 is set to the level having the highest probability of being used most based on the level change situation in many karaoke apparatuses. Since the setting is performed, the frequency at which the user performs key level adjustment during singing can be reduced.

Further, by examining the music data registered in the center device 1, the key level preferred by many users for each karaoke music can be easily determined, and the result of the determination is used as the music data. It can be used later as reference information when setting the default key level.

Next, the center apparatus 1 of the communication karaoke system automatically changes the default key level set in the music data of the karaoke music based on the use state of the key adjustment for each predetermined time period on the karaoke apparatus 2 side. The function to be performed will be described. In order to realize this function, the system control unit 101 or the like of the karaoke apparatus 2 has a function of transmitting to the center apparatus 1 the number of times of playing a music piece, the adjustment value adjusted by the pitch adjustment means, and the number of adjustments. Fulfill.

The control device 14 of the center device 1 defaults the performance music at predetermined time intervals based on the number of performances of the performance music received from the karaoke device 2, the adjustment value, and the number of adjustments. When it is determined that the number of times of performing with a value other than the pitch value is larger than a predetermined number and the pitch value is biased toward one of the higher pitch and the lower pitch than the above-mentioned default pitch value, The function of a means for changing the default pitch value of the musical piece to the pitch value at the center of the bias is performed.

First, the karaoke apparatus 2 stores the above-described interval history file 1 for time zone 1 and interval history file 2 for time zone 2 in the hard disk device 109. When the karaoke device 2 receives a song number for selecting a karaoke song from the remote control 21 or the operation panel 108 in the time zone 1, the system control unit 101 inputs the song number and the pitch history file stored in the hard disk device 109. The number of the karaoke tune of the song number is incremented by one if the corresponding song number exists in the pitch history file 1, and if there is no corresponding song number, the corresponding song number is stored in the pitch history file 1. A column related to the number is added, and the number of performances in the column is set to 1, and the performance of the karaoke music is started.

When the performance of the karaoke music is completed, if the performance is performed at a key level other than the default, the pitch history file 1 is updated by incrementing the number of adjustments of the key level by “1”. Further, for the time period 2, the pitch history file 2 is similarly updated.

System control section 101 of karaoke apparatus 2
Periodically checks the pitch history files 1 and 2 stored in the hard disk device 109, and, if the number of adjustments of the up level or down level is not all "0", only the song number, the number of performances, and each key The number of level adjustments is transmitted to the center device 1 via the communication network 3 together with the time zone information. After the transmission, the number of times of performance of all the songs in the pitch history files 1 and 2 and the number of times of adjustment of each key level are initialized to "0".

Next, according to the flowchart of FIG.
A process in which the karaoke apparatus 2 transmits key adjustment information for each time zone to the center apparatus 1 will be described. In this processing, it is determined whether or not a predetermined period has elapsed in step 71, and when it has elapsed, initial setting is made to N = 1 and K = 1 in step 72, the pitch history file K is read in step 73, and step 74
First, it is determined whether or not the number of adjustments of the up level or the down level is all "0" for each music number in the pitch history file 1.

If the number of adjustments of the up level or the down level is not all "0" in the judgment of step 74, the number of music pieces in the time zone 1, the number of performances, and the number of adjustments of each key level are transmitted in the format of the pitch history file. It is stored in the main memory 103 as data, and it is determined in step 76 whether or not all the song numbers have been checked. If all the song numbers have not been checked, N is updated to N = N + 1 in step 80,
Returning to step 74, a check is performed for the next song number in time zone 1.

If all song numbers have been checked in step 76, it is determined in step 77 whether or not K = 2. If K = 2, K = K + 1 is updated in step 81 and the process returns to step 73. To read the pitch history file 2 and perform the processes of steps 74 to 75 to read the pitch history file 2
, The number of adjustments of the corresponding music number is extracted and stored in the main memory 103 in the format described above.

When all the music numbers in the time zone 2 have been checked in step 76, the transmission data stored in the main memory 103 is transmitted to the center device 1 in step 78, and the pitch history file 1 is stored in step 79. "0" is set to the number of times of playing of all song numbers in 2 and the number of times of adjusting each key level.
And ends this processing.

Next, a process in which the center apparatus 1 automatically changes the default key level set in the music data of the karaoke music based on the use status of the karaoke apparatus 2 will be described.

First, the center device 1 is stored in the storage device 13 in advance.
And a pitch statistic file 1 for time zone 1 and a pitch statistic file 2 for time zone 2. This pitch statistics file is
This file has the same format as the pitch history file shown in FIG. 6, and stores the number of performances for each music number and the number of adjustments of each key level transmitted from the karaoke apparatus 2 as an accumulated value. Further, unlike the pitch history file shown in FIG. 8, the setting key level column is not provided.

When the center apparatus 1 receives the tune number of the time zone 1, the number of plays, and the number of adjustments of each key level from each karaoke apparatus 2, the number of plays of the same tune number in the pitch statistic file 1 and each key level The file is updated by adding each to the number of adjustments of. Subsequently, when the tune number of the time zone 2, the number of times of playing, and the number of times of adjustment of each key level are received from each karaoke apparatus 2, the number of times of playing of the same number of songs and the number of times of adjusting each key level of the pitch statistical file 2 are respectively obtained. Add and update the file.

When the center apparatus 1 receives a request for music data from the karaoke apparatus 2, first, the center apparatus 1 checks the distribution of the number of times of adjustment of each key level of the requested music number in the pitch statistic file 1, and checks the down level or the up level. It is determined whether the count value is biased to one of the levels.
If there is a bias in this judgment, it is checked whether or not a value obtained by dividing the total value of the number of times of adjustment of each key level of the song number by the number of times of playing of the song number is larger than a predetermined number.

When the value is larger than the predetermined number in the above check,
The degree of bias, that is, the key level at the center of the count value distribution is determined, and the time information of time zone 1 and the determined key level are recorded in an information file in the song data of the song number.

Further, the distribution of the number of times of adjustment of each key level of the requested music number in the pitch statistical file 2 is examined, and it is determined whether or not the count value is biased to either the down level or the up level. If there is a bias in this judgment, it is checked whether or not a value obtained by dividing the total value of the number of times of adjustment of each key level of the song number by the number of times of playing of the song number is larger than a predetermined number.

Similarly, when a song number for selecting karaoke music is input from the remote controller 21 or the operation panel 108 in the time period 2, the system control unit 101 stores the input song number and the hard disk device 109 to store the input song number. The music number in the pitch history file 2 is compared.

If the above check indicates that the number is larger than the predetermined number,
The degree of bias, that is, the key level at the center of the distribution of the count value is obtained, and the time information of the time zone 2 and the obtained key level are recorded in the information file in the music data of the music number. Then, the music data is transmitted to the karaoke apparatus 2 which has made the request.

FIG. 13 is a diagram showing a format of music data at the time of the processing. In the information file of the music data, information on the start time and the key level for the time zones 1 and 2 are stored together with the information on the genre type.

The karaoke device 2 stores the music data transmitted from the center device 1 in the hard disk device 109,
The karaoke music is played at the key level of time zone 1 or time zone 2 in the information file of the music data according to the time of the request by the user.

Next, according to the flowchart shown in FIG. 14, the center apparatus 1 automatically changes the default key level set in the music data of the karaoke music based on the usage status of the karaoke apparatus 2 for each time zone. Further explanation will be given.

In this process, it is determined at step 91 whether or not there is a request for music data from the karaoke apparatus 2, and if so, K = 1 is initially set at step 92. The file 1 is read, and it is determined in step 94 whether the number of times of adjustment of the song number requested by the karaoke apparatus at each key level is biased in one of the up direction (up level) and the down direction (down level). I do.

If it is determined in step 94 that the number of adjustments of the up level or the down level is not biased to either direction, the process proceeds to step 99, and if it is biased, in step 95, the total value of the number of adjustments of each key level is calculated by A value M obtained by dividing the number of performances is obtained, and it is determined in step 96 whether the value M is larger than a predetermined number.

If it is not large, the process proceeds to step 99. If it is large, in step 97, the key level at which the distribution of the number of adjustments of each key level is centered is determined.
In step 98, the key level at the center is written to a predetermined position associated with time zone 1 in the information file in the music data format for transmission.

At step 99, it is determined whether or not K = 2. When the above processing is completed for time zone 1, K = K + 1 is set at step 101, and the flow returns to step 93 to read the pitch statistical file 2. The key level which is the center of the use situation for the time period 2 is obtained by the processing of steps 94 to 99, written in a predetermined position of the music data for transmission, and the music data is transmitted to the requesting karaoke device in step 100, It returns to step 91.

If there is no request for song data from the karaoke apparatus in step 91, it is determined in step 102 whether the tune number of the time zone 1, the number of plays, and the number of adjustments of each key level have been received from the karaoke apparatus. Is determined, and if not received, the process proceeds to step 104.
At 03, the number of times of performance and the number of times of adjustment of each key level are added to the corresponding value of the same music number in the pitch statistical file 1, and the routine proceeds to step 104.

At step 104, it is determined whether or not the tune number of the time zone 2, the number of times of playing, and the number of times of adjustment of each key level have been received from the karaoke apparatus.
Returning to step 1, if received, the number of times of performance and the number of times of adjustment of each key level are added to the corresponding value of the same music number in the pitch statistical file 2 in step 105, and the process returns to step 91.

Further, this center device totalizes the number of key level adjustments (count information) received from each karaoke device, stores the totaled result in the storage device 13 as a file, and displays it on the display device 12, For example, a printing device (printer) (not shown) records and outputs on paper.

As described above, the default key level of the music data distributed by the karaoke apparatuses 2 from the center apparatus 1 is determined by the most karaoke apparatuses based on the level change status of each time zone. Since the level is set to a level having a high probability of being used, the frequency at which the user adjusts the key level during singing can be reduced.

Further, by examining the music data registered in the center device 1, it is possible to easily determine the most preferred key level for each karaoke user for each karaoke music. Can be used later as reference information when setting the default key level of the song data.

Next, the center apparatus 1 of the communication karaoke system automatically changes the default tempo value (tempo level) set in the karaoke music piece data based on the utilization state of the tempo adjustment on the karaoke apparatus 2 side. The function will be described.

In order to realize this function, the system control section 101 of the karaoke apparatus 2 and the like perform performance music with a default tempo value based on the performance information distributed from the center apparatus 1, and the performance means. A tempo adjusting means for adjusting the tempo value of the music piece being played, and a means for transmitting to the center device the number of times the music piece has been played, the adjustment value adjusted by the tempo adjusting means, and the adjustment number. .

Further, the control device 14 or the like of the center device 1 plays the performance music at a value other than the default tempo value based on the number of times of performance and the adjustment value and the number of adjustments of the performance music received from the karaoke device 2. When it is determined that the number of times is greater than the predetermined number and the tempo value is biased to one of a higher speed and a lower speed than the default tempo value, the default tempo value of the musical piece is changed to the above-mentioned biased tempo value. Acts as a means of changing to a central tempo value.

First, as described above, the remote controller 21 or the operation panel 108 of the karaoke apparatus 2 adjusts the default key level of the karaoke music to a high pitch and a four-level level up key and a low pitch. A four-level down key is provided, and the key level before and during the performance can be adjusted stepwise by the key input.

Further, the remote control 21 or the operation panel 10
8 has a four-step level up key for adjusting the default performance speed (tempo level) of karaoke music at a high speed and a four-step level down key for adjusting the speed to a low speed. And the tempo level during the performance can be adjusted step by step. After the performance, the tempo level and the key level are automatically returned to the default values.

When the user inputs a song number for selecting karaoke music from the remote control 21 or the operation panel 108, the system control unit 101 inputs the song number and the pitch history stored in the hard disk device 109 to the karaoke device 2. The file is compared with the song number in the tempo history file, and it is determined whether or not the input song number exists.

As described with reference to FIG. 6, this pitch history file is a file for recording the history of the number of key level adjustments at the time of playing each karaoke music. The key and the number of adjustments for each level of the level down key are recorded.

The tempo history file is a file for recording the usage status of tempo adjustment for each karaoke music, and shows the number of times the tempo value (tempo level) has been adjusted during the performance of each karaoke music in the format shown in FIG. The history records the number of times of performance and the number of times of adjustment for each song number of karaoke music (performed music). In the karaoke apparatus 2, the number of adjustments is counted for each level of the level up key and the level down key on the remote controller 21 or the operation panel 108, and recorded for each of the four down levels and the four up levels.

If there is a corresponding song number in the pitch history file as a result of the above verification, the number of times of performing the karaoke music of that song number is incremented by 1. If there is no corresponding song number, the song number is additionally registered in the pitch history file. The number of performances is set to 1.

If there is a corresponding song number in the tempo history file, the number of times of performing the karaoke music of that song number is incremented by 1. If there is no corresponding song number, the song number is additionally registered in the tempo history file. The number of performances is set to 1, and the performance of the karaoke music is started.

When the performance of the karaoke music is completed and the performance is performed at a key level other than the default key level, the number of adjustments of the corresponding key level is incremented by one, and the tempo level other than the default tempo level is increased. Is performed, the number of adjustments of the corresponding tempo level is incremented by one. In this way, the pitch history file and the tempo history file are updated.

Thereafter, when a predetermined period elapses, the system control unit 101 calls the center device 1 and
The pitch history file and the tempo history file stored in the hard disk device 109 are transmitted. After the transmission, the number of times of playing all songs in the pitch history file and the number of times of adjustment of each key level are initialized to "0", and the number of times of playing all songs in the tempo history file and the number of times of adjusting each tempo level Is initialized to “0”.

Further, the center device 1 counts the number of tempo level adjustments (count information) received from each karaoke device 2, saves the count result in the storage device 13 as a file, and displays the result on the display device 12. Alternatively, the information is recorded on paper by a printing device (printer) not shown.

As described above, the default tempo level of the music data distributed by the karaoke apparatuses 2 from the center apparatus 1 is set to be the most appropriate for most karaoke apparatuses based on the level change situation for each time zone. Since the level is set to a level with a high probability of being used, the frequency at which the user adjusts the tempo level during singing can be reduced.

Further, by examining the music data registered in the center device 1, the most preferred tempo level for each age group of the user for each karaoke music can be easily determined. Can be used later as reference information when setting the default tempo level of the song data.

Further, the processing in which the karaoke apparatus 2 transmits the pitch history file and the tempo history file to the center apparatus 1 will be described with reference to the flowchart of FIG. In this process, it is determined in step 111 whether or not a predetermined period has elapsed, and when it has elapsed, in step 112, a pitch history file and a tempo history file are transmitted to the center device.

In step 113, the number of performances of all music numbers in the pitch history file and the number of adjustments of each key level are initialized to "0". In step 114, the number of performances of all music numbers in the tempo history file, The number of tempo level adjustments is initialized to “0”, and this process ends.

Next, a description will be given of a process in which the center apparatus 1 automatically changes the default key level and the tempo level set in the music data of the karaoke music based on the use state of the key adjustment and the tempo adjustment of the karaoke apparatus 2. .

The center device 1 stores the data in FIG.
15 and a tempo statistics file in the same format as the tempo history file shown in FIG. 15 and a pitch statistics file in the same format as the pitch history file shown in FIG. This tempo statistics file is a file that stores the number of times of performance for each song number and the number of times of adjustment of each tempo level transmitted from the karaoke apparatus 2 as an accumulated value.

When the center apparatus 1 receives the pitch history file and the tempo history file from each of the karaoke apparatuses 2, the center apparatus 1 determines the number of performances of the pitch history file and the number of adjustments of each key level, the number of times of playing the same music number in the pitch statistical file, Add the number of adjustments for each key level to the number of times played in the tempo history file and the number of adjustments for each tempo level to the number of times played for the same song number and the number of adjustments for each tempo level in the tempo statistics file. Update.

The center apparatus 1 checks the distribution of the number of times of adjustment of each key level for each music number in the pitch statistical file at predetermined time intervals, for example, every month, and checks the down level or the up level. It is determined whether the count value is biased to one of the two. If there is a bias in this judgment, it is checked whether or not a value obtained by dividing the total value of the number of times of adjustment of each key level of the song number by the number of times of playing of the song number is larger than a predetermined number.

If the above check indicates that the number is larger than the predetermined number,
Determine the degree of bias, that is, the key level at the center of the distribution of the count value, overwrite the key level at the center with the default key level in the song data of the song number,
Change the default value of the key level.

Further, the distribution of the number of times of adjustment of each tempo level is checked for each music number in the tempo statistics file, and it is determined whether or not the count value is biased to either the down level or the up level. If there is a bias in this determination, it is checked whether or not a value obtained by dividing the total value of the number of times of adjustment of each tempo level of the song number by the number of times of playing of the song number is larger than a predetermined number.

If the above check indicates that the number is larger than the predetermined number,
The degree of bias, that is, the tempo level at the center of the distribution of the count value is obtained, and the MID in the music data of the music number is obtained.
The default tempo level is changed by overwriting the default tempo level in the I file with the center tempo level.

Thereafter, when the karaoke device 2 requests song data, the updated song data is distributed, and the karaoke device 2 sets default values based on the key level and tempo level usage of many users. Perform karaoke music with the changed song data.

Further, according to the flowchart shown in FIG. 17, the center apparatus 1 performs the performance of the default key level and tempo level set in the music data of the karaoke music based on the utilization state of the key adjustment and the tempo adjustment of the karaoke apparatus 2. The process of automatically changing the condition will be described.

In this process, it is determined in step 121 whether or not a pitch history file has been received from the karaoke apparatus.
If not received, the process proceeds to step 123. If received, the file is updated by adding the number of times of performance and the number of times of adjustment of each key level in the pitch history file to the corresponding value of the same music number in the pitch statistical file in step 122. .

At step 123, it is determined whether or not a tempo history file has been received.
25, if received, the number of performances in the tempo history file and the number of adjustments of each tempo level are added to the corresponding value of the same music number in the tempo statistics file to update the file in step 124.

In step 125, it is determined whether or not a predetermined period has elapsed. When the predetermined period has elapsed, the pitch statistical file is read in step 126, and the distribution of the number of times of adjustment of each key level is checked for all the music numbers in the pitch statistical file. For each song number, it is determined whether the number of adjustments of the up level or the down level is biased to one or the other, and if so, the total value of the number of adjustments of each key level is divided by the number of times the song number is played. A value M is determined, and whether the value M is greater than a predetermined number is determined. If the value M is greater, a key level in which the distribution of the number of adjustments of each key level is centered is determined. , Overwrites the default key level in the information file of the music data of the music number, and proceeds to step 127.

In step 127, the tempo statistics file is read, and the distribution of the number of adjustments of each tempo level is checked for all the music numbers in the tempo statistics file. Is determined, and if so, a value M is obtained by dividing the total value of the number of times of adjustment of each tempo level by the number of times of playing the song number, and whether the value M is greater than a predetermined number. If it is larger, the tempo level at which the distribution of the number of adjustments of each tempo level is centered is determined, and the tempo level at the center is determined by the M of the music data of the music number.
This overwrites the default tempo level in the IDI file, and ends this processing.

Further, this center device tallies the count information of the number of key level adjustments and the number of tempo level adjustments received from each karaoke device, stores the totaled result in the storage device 13 as a file, and displays the result on the display device 12.
, Or recorded and output on paper by a printing device (printer) not shown.

As described above, the default key level and tempo level of the music data distributed from the center apparatus 1 to each karaoke apparatus 2 are determined based on the change state of the key level and tempo level in many karaoke apparatuses. Since it is set to the level with the highest probability of being used, the frequency at which the user adjusts the key level and the tempo level during singing can be reduced, and a singing environment that is easy for the user to sing can be provided. it can.

Further, by examining the music data registered in the center device 1, it is possible to easily determine the key level and the tempo level preferred by many users for each karaoke music. This can be used later as reference information when setting the default key level and tempo level of the song data.

In the above-described processing related to the change of the key level and the tempo level, the center apparatus 1 sets the default of the tempo level and the key level based on the key adjustment and the utilization state of the tempo adjustment of the karaoke apparatus 2 for each predetermined time period. The value may be changed for each time zone.

Next, a description will be given of a process in which the center apparatus 1 periodically distributes the music data after updating the default key level and tempo level to each karaoke apparatus 2 in this communication karaoke system. In order to realize this function, the control device 14 or the like of the center device 1 functions as a means for distributing the changed performance information to the karaoke device 2 periodically or at a predetermined time.
