Description

  In the karaoke apparatus, the performance data includes data indicating the timbre setting of the guide melody a plurality of times, and the melody type of the guide melody is changed from the change target timbre to the change non-target timbre before the change. The present invention relates to a technique for preventing a difference between the various settings related to the guide melody in the original change target timbre and the various settings related to the guide melody in the changed target timbre after the return even when the timbre is returned to the timbre type.

  Conventionally, a karaoke apparatus having a function of performing karaoke performance based on performance data including a guide melody is known. Here, the guide melody refers to a melody part (track) that is played to assist a person who wants to sing along with a karaoke performance when he or she remembers the main melody. This guide melody is created with various timbres for each musical piece, assuming that it is basically used in a karaoke box, which is the main installation location. Specific examples of the timbre type used for the guide melody include vibraphone, piano, flute, harmonica, and the like.

Some karaoke apparatuses as described above change the length and pitch of a note of a guide melody (see, for example, Patent Document 1). Some karaoke apparatuses as described above change the volume of the guide melody (see, for example, Patent Document 2).
Japanese Patent Laid-Open No. 2000-267652 (page 4, FIGS. 2, 3 and 6) JP-A-9-81166 (5th page, FIG. 1)

  However, in the karaoke apparatus as described above, for example, when the performance data of a certain reserved song has an operation format in which the timbre change is performed only for a specific timbre, as shown in FIG. When data indicating the timbre setting of the guide melody a plurality of times is included in the data, the timbre type of the guide melody is changed. At the time of changing the timbre type of the guide melody, for example, from a timbre that is a timbre change target timbre such as a harmonica (change target timbre) to a timbre that is not a timbre change target such as a vibraphone (change non-target timbre) Some cases may change. At this time, various settings (effect parameters) related to the guide melody are also changed to the setting contents corresponding to the changed non-target timbre. After such a melody change of the guide melody, if there is an instruction to change the melody type of the guide melody from the change non-target timbre to the change target timbre, as illustrated in FIG. Various settings related to the melody remain the same as the settings corresponding to the non-changed timbre, which means that there is a difference between the various settings related to the guide melody in the original change target timbre and the various settings related to the guide melody in the change target timbre after restoration. This may cause a sense of discomfort when performing a karaoke performance based on the performance data.

  The present invention has been made in view of such problems, and the object of the present invention is to include data indicating the timbre setting of a plurality of times of the guide melody in the performance data in the karaoke device. Even if the melody type of the guide melody is changed to the non-changed timbre and then changed back to the timbre type before the change, the various settings related to the guide melody in the original change timbre and the timbre to be changed after restoration It is to provide a technique for preventing a difference between various settings related to guide melodies in Japan.

  The karaoke apparatus according to claim 1, which has been made in order to solve the above-mentioned problem, “stores the type of timbre of an effective guide melody and various corresponding setting contents when changing the timbre type of the guide melody. After that, when returning the melody type of the guide melody to the type before the change, the melody type of the guide melody is changed again based on the memorized type of the guide melody and the corresponding settings. To do ".

  Specifically, the performance data storage means (16: In this column, in order to facilitate understanding of the invention, the reference numerals used in the “Best Mode for Carrying Out the Invention” column are attached as necessary. This code does not mean that the scope of claims is limited.) However, the performance data created in the MIDI data format is stored, including the guide melody in which the tone is designated, and the karaoke performance means ( 30) performs a karaoke performance based on the performance data acquired from the performance data storage means by the performance data acquisition means (12). Further, the buffer (24g) can temporarily store the performance data acquired by the performance data acquisition means, and the change data acquisition means (24e) indicates “change data to change the tone type of the guide melody. Can be acquired. Further, the setting information correspondence table storage means (24e) stores a setting information correspondence table in which the type of timbre of the guide melody and “guide melody setting information” indicating the setting contents related to the guide melody are associated with each other.

  When the change data is acquired by the change data acquisition means, the setting information specifying means (24e) sets the guide melody setting information corresponding to the tone type of the guide melody indicated by the change data to the setting information. The effective setting specifying means (24e) refers to the performance data stored in the buffer and specifies the type of timbre of the effective guide melody and the effective information by referring to the setting information correspondence table stored in the table storage means. Specify guide melody setting information. Further, the storage control means (24e) stores the “tone color type information” and the “guide melody setting information” indicating the tone type of the guide melody specified by the valid setting specifying means in the setting information storage means. Update the contents. When the change data is acquired by the change data acquisition unit as described above, the data update unit (24e) determines that “change data” and “setting data (after change) specified by the setting information specifying unit” Is inserted into the performance data stored in the buffer to update the performance data.

  Further, when the release data acquisition means (24e) can acquire "release data" for canceling the change of the tone type of the guide melody by the change data, and the release data is acquired by the release data acquisition means In this case, the data updating means reads “timbre type data” and “setting data (before change)” from the setting information storage means, and inserts the read tone type data and setting data into the performance data stored in the buffer. To update the performance data.

  In the conventional karaoke apparatus, data indicating the timbre setting of the guide melody a plurality of times is included in the performance data, and the melody type of the guide melody is changed from the change target timbre to the change non-target timbre before the change. When the timbre type is restored, there may be a difference between the various settings related to the guide melody in the original change target timbre and the various settings related to the guide melody in the change target timbre after the return (FIG. 3). (See (b)).

  On the other hand, according to the present invention, when the change data is acquired by the change data acquisition means, the setting information storage means stores the type of tone color of the effective guide melody and the setting information regarding the effective guide melody. After that, when the release data is acquired by the release data acquisition means, “tone color type data” and “setting data” are read from the setting information storage means, and the read tone color type data and setting data are stored in the buffer. The performance data is updated by inserting it into the data. That is, as illustrated in FIG. 4, when changing the timbre type of the guide melody, the timbre type of the effective guide melody and the corresponding various settings are stored, and then the melody of the guide melody is changed. When returning the type to the type before the change, the type of the melody of the guide melody is changed again based on the stored type of the timbre of the guide melody and various corresponding settings. As a result, the performance data includes data indicating the timbre setting of the guide melody multiple times, and the timbre type before the change after the melody type of the guide melody is changed from the change target timbre to the change non-target timbre Even when the setting is restored, it is possible to prevent a difference between the various settings related to the guide melody in the original change target tone color and the various settings related to the guide melody in the change target tone after the return.

Specific examples of setting information related to the guide melody include information related to echo, information related to reverb, information related to effects, and the like.
The performance data is composed of a plurality of MIDI tracks, and at least one of the plurality of MIDI tracks is used as a guide melody track.

  Moreover, about the above-mentioned change data, (a) For example, the case where it inputs from the operation part (18) with which the said karaoke apparatus is equipped, remote control terminal (2), etc., or the case where it is contained in (b) performance data can be considered. In the case of (a), the change data acquisition means described above changes the tone type of the guide melody input from, for example, the operation unit (18) or the remote control terminal (2) provided in the karaoke device. Can be obtained as the above-mentioned changed data. In the case of (b), it is conceivable that the above-described change data acquisition means acquires change data from performance data temporarily stored in the buffer.

  As a method of acquiring change data from the performance data temporarily stored in the buffer as described above (b), (c) acquiring all the performance data scheduled to perform karaoke performance from the performance data storage means. A method of temporarily storing data in a buffer and detecting change data from the performance data stored in the buffer, or (d) changing performance data from the performance data stored in the buffer during acquisition of performance data scheduled for karaoke performance A method for detecting the error can be considered.

  Further, as described above, as a method of acquiring the change data from the performance data temporarily stored in the buffer, (c) all the performance data scheduled to perform karaoke performance is acquired from the performance data storage means and temporarily stored in the buffer. A method for detecting change data from the performance data stored in the buffer, and (d) a method for detecting the change data from the performance data stored in the buffer during acquisition of the performance data scheduled to perform karaoke performance Can be considered.

  Among these, for the above (c), the change data acquisition means changes the performance data stored in the buffer after the performance data is acquired from the performance data storage means by the performance data acquisition means and stored in the buffer. It is conceivable to obtain change data by detecting data.

  In this way, compared with the above-mentioned case (d), the activation frequency of the above-mentioned change data detection process can be reduced, and the processing load of the change data acquisition means can be reduced. Further, if the above-described processing is executed for a reserved song, the above-described processing can be performed during the performance of a performance song reserved before the reserved song. However, since all performance data scheduled to perform karaoke performance is temporarily stored in the buffer, it is necessary to increase the capacity of the buffer storage area as compared with the above case (d).

  For (d) above, more specifically, a method of executing the change data detection process every time a predetermined time elapses can be considered. That is, it is conceivable that the change data acquisition means acquires the change data by detecting the change data from the performance data stored in the buffer during the predetermined time.

  In this way, the capacity of the buffer storage area can be reduced. However, the execution frequency of the above-described change data detection process increases, and the processing load of the change data acquisition unit increases.

  Similarly, the release data described above may be (e) input from, for example, the operation unit (18) or the remote control terminal (2) included in the karaoke device, or (f) included in the performance data. It is done. In the case of (e), the above-described release data acquisition means restores the tone type of the guide melody input from the operation unit (18), the remote control terminal (2), etc. provided in the karaoke device, for example. It is conceivable that data indicating this is acquired as the release data. In the case of (f), it is conceivable that the above-described release data acquisition means acquires release data from performance data temporarily stored in the buffer.

  Further, as a method of acquiring the release data from the performance data temporarily stored in the buffer as described in (f) above, (g) acquiring all the performance data scheduled to perform the karaoke performance from the performance data storage means. Temporary storage in a buffer and detection of release data from performance data stored in the buffer, or (h) release data from performance data stored in the buffer during acquisition of performance data scheduled for karaoke performance A method for detecting the error can be considered.

  Among the above, regarding (g), as described in claim 2, the release data acquisition means stores the performance data in the buffer after the performance data is acquired from the performance data storage means by the performance data acquisition means. It is conceivable to obtain the release data by detecting the release data from the stored performance data.

  In this way, the execution frequency of the release data detection process described above can be reduced and the processing load of the release data acquisition means can be reduced compared to the case of (H) described above. Further, if the above-described processing is executed for a reserved song, the above-described processing can be performed during the performance of a performance song reserved before the reserved song. However, since all performance data scheduled to be played karaoke are temporarily stored in the buffer, it is necessary to increase the capacity of the buffer storage area as compared with the case (1) above.

  As for the above (h), more specifically, a method of executing the release data detection process every time a predetermined time elapses can be considered. That is, as in claim 3, it is conceivable that the release data acquisition means acquires the release data by detecting the release data from the performance data stored in the buffer during a predetermined time.

  In this way, the capacity of the buffer storage area can be reduced. However, the frequency of execution of the release data detection process described above increases, and the processing load on the release data acquisition means increases.

  By the way, a chord may be included in the guide melody, for example. In such a case, multiple note-on signals may be valid at the same time, and even if one of the note-off signals of the sound that makes up the chord is detected, the note-on of other sounds that make up the chord is detected. The state in which the signal is valid is maintained.

  Therefore, when executing data update, it is conceivable to insert various data into an area where no valid note-on signal exists. Specifically, as described in claim 4, when the data updating means updates the performance data, it detects an area where there is no valid note-on signal in the guide melody from the performance data stored in the buffer. The performance data may be updated by inserting various data into the detected area.

  In this way, for example, when a chord is included in the guide melody and a plurality of note-on signals are valid at the same time, the note-on signals of all the sounds constituting the chord of the guide melody are invalidated. Since the timbre and sound settings are changed after becoming a chord, for example, even if a chord is included in the guide melody, the timbre and sound settings of the chord are changed during performance to prevent a sense of incongruity. Can do.

  As shown in claim 5, the setting information specifying means, valid setting specifying means, storage control means, and data updating means in the karaoke apparatus according to any one of claims 1 to 4 cause the computer to function. It can be realized as a program. Therefore, the present invention can be realized as a program invention. In the case of such a program, for example, the program is recorded on a computer-readable recording medium such as an FD, MO, DVD-ROM, CD-ROM, or hard disk, and is used by being loaded into a computer and started up as necessary. be able to. In addition, the ROM or backup RAM may be recorded as a computer-readable recording medium, and the ROM or backup RAM may be incorporated into the computer for use.

[Input Acceptance Processing of Control Unit 12 of Karaoke Apparatus 1]
Below, the process sequence of the input reception process performed by the control part 12 of the karaoke apparatus 1 is demonstrated based on the flowchart of FIG. This input reception process is repeatedly executed while the karaoke apparatus 1 is activated.

First, in step S110, a music selection table for storing music selection information of karaoke performances reserved by the user is initialized (see FIG. 5B).
In subsequent S120, it is determined whether or not the user has input music selection information via the operation unit 18. If there is no input of music selection information via the operation unit 18 (S120: No), this step S120 is repeatedly executed to wait until the user inputs music selection information via the operation unit 18. . On the other hand, when the music selection information is input via the operation unit 18 (S120: Yes), the process proceeds to S130.

  In S130, it is determined whether or not the stored contents of the music selection table are full. If the stored content of the music selection table is full (S130: Yes), new music selection information cannot be stored until there is an empty space in the storage content of the music selection table due to the end of the performance. It returns and repeatedly performs the processing after S120. On the other hand, when it is determined that the stored contents of the music selection table are full (S130: No), the process proceeds to S140.

In S140, the music selection information input via the operation unit 18 in S120 is registered in the music selection table. Then, the process proceeds to S120.
[Main processing of control unit 12 of karaoke apparatus 1]
Below, the process sequence of the main process performed by the control part 12 of the karaoke apparatus 1 is demonstrated based on the flowchart of FIG. This main process is repeatedly executed while the karaoke apparatus 1 is activated. Further, the main process and the above-described input reception process are asynchronously executed in parallel by the multitask process in the control unit 12.

First, in step S210, various initialization processes are executed. For example, the operation unit 18 may wait for input.
In the subsequent S220, BGM data for playing as BGM when waiting for music selection is read from the HDD 16 and transmitted to the audio control unit 24 via the USB 40.

In subsequent S230, an instruction to reproduce the BGM data transmitted to the voice control unit 24 in previous S220 is sent to the voice control unit 24.
In subsequent S240, it is determined whether or not music selection information has been input to the music selection table in S140 of the above-described input reception process. When the music selection information is input to the music selection table (S240: Yes), the process proceeds to S260 described later. On the other hand, when the music selection information is not input to the music selection table (S240: No), the process proceeds to S250.

  In S250, it is determined whether or not the performance of the BGM data by the voice control unit 24 is finished. If the performance of the BGM data by the voice control unit 24 has not ended (S250: No), the process returns to S240. On the other hand, if the performance of the BGM data by the voice control unit 24 has been completed (S250: Yes), the process proceeds to S220 in order to send the next BGM data to the voice control unit 24 for performance while waiting for music selection. To do.

  Now, in S260, where the process proceeds to the case where the music selection information is input to the music selection table in the previous S240, the performance of the BGM data is stopped in order to perform the music based on the music selection information input to the music selection table. Is transmitted to the voice control unit 24.

  In subsequent S270, it is determined whether or not the leading portion in the storage area of the music selection table is empty. If the head portion in the storage area of the music selection table is empty (S270: Yes), it is determined that the music selection is awaited, and the process proceeds to S220 to play the BGM data during that time. On the other hand, when the head portion in the storage area of the music selection table is not empty and music selection information is registered (S270: No), the process proceeds to S280.

  In S280, it is determined whether or not the music selection information registered in the head portion of the music selection table storage area is a music number. When the music selection information registered at the head part in the storage area of the music selection table is not the music number (S280: No), the process proceeds to S270. On the other hand, when it is determined that the music selection information registered at the head portion in the storage area of the music selection table is a music number (S280: Yes), the process proceeds to S290.

In S290, the performance data corresponding to the music number, which is the music selection information registered in the head portion of the music selection table storage area, is read from the HDD 16 and transmitted to the audio control unit 24.
In subsequent S300, it is determined whether to change the setting of the guide melody with reference to the feature information. The feature information refers to information indicating features relating to the place where the karaoke apparatus 1 is installed. In addition, the characteristics of the installation location arise from the difference in the customer base and the atmosphere. For example, in the karaoke box, the customer base is mainly young people, and the atmosphere is relatively noisy. In snacks and night clubs, The customer base is middle-aged and older, and the atmosphere is relatively quiet and relaxed. Such feature information is input via the operation unit 18, a remote control terminal, an external host computer, or the like. If it is determined not to change the setting of the guide melody (S300: No), the process proceeds to S320 without processing S310. On the other hand, if it is determined that the setting of the guide melody is to be changed (S300: Yes), a message to change the guide melody is transmitted to the voice control unit 24, and the process proceeds to S320.

In S320, in order to start performance of the performance data transmitted to the voice control unit 24 in the previous S290, an instruction to that effect is transmitted to the voice control unit 24.
In the subsequent S330, the first portion in the storage area of the music selection table is initialized and the other stored contents are sequentially advanced as an empty state.

  In subsequent S340, it is determined whether or not the performance of the performance data by the audio control unit 24 has been completed. If the performance of the performance data by the voice control unit 24 has not been completed (S340: No), the process waits until the performance of the performance data is completed by repeatedly executing this S340. On the other hand, if the performance of the performance data by the audio control unit 24 has been completed (S340: Yes), the process proceeds to S270 to transmit the next performance data to the audio control unit 24 for performance.

[Main process of voice control unit 24 of karaoke apparatus 1]
Below, the process sequence of the main process performed by the audio | voice control part 24 of the karaoke apparatus 1 is demonstrated based on the flowchart of FIG.

This main process is repeatedly executed while the karaoke apparatus 1 is activated.
First, in step S610, it is determined whether or not performance data is transmitted from the control unit 12. When it is determined that the performance data is transmitted from the control unit 12 (S610: Yes), the performance data is received. Then, the performance data in the MIDI format composed of a plurality of tracks is converted into a MIDI transfer byte string and stored in the work area 24g of the RAM 24d.

On the other hand, when it is determined that the performance data is not transmitted from the control unit 12 (S610: No), the process proceeds to S620.
In S620, it is determined whether an instruction to change the guide melody is transmitted from the control unit 12. When it is determined that an instruction to change the guide melody is transmitted from the control unit 12 (S620: Yes), the instruction is received and stored in the work area 24g of the RAM 24d. On the other hand, when it is determined that the instruction to change the guide melody has not been transmitted from the control unit 12 (S620: No), the process proceeds to S630.

  In S630, it is determined whether or not an instruction to start playing the performance data is transmitted from the control unit 12. When it is determined that an instruction to start performance data is not transmitted from the control unit 12 (S630: No), the process proceeds to S610. On the other hand, if it is determined that an instruction to start playing the performance data is transmitted from the control unit 12 (S630: Yes), the process proceeds to S640.

  In S640, it is determined whether reception of performance data has been completed. If it is determined that reception of performance data has not been completed (S640: No), the process proceeds to S610. On the other hand, when it is determined that the reception of the performance data has been completed (S640: Yes), performance processing described later is executed (S650). Then, when the performance process is completed, information indicating that is sent to the control unit 12, and the instruction to change the guide melody stored in the work area 24g of the RAM 24d is deleted in the previous S625. And it transfers to S610 and performs the following steps repeatedly.

[Performance processing of the voice control unit 24 of the karaoke apparatus 1]
Below, the process procedure of the performance process performed by the audio | voice control part 24 of the karaoke apparatus 1 is demonstrated based on the flowchart of FIG. 8, and FIG. FIG. 4 is an explanatory diagram showing MIDI data. This performance process is executed when the process proceeds to S650 in the main process of the audio control unit 24.

First, in step S710, the time per step is calculated from the tempo value.
In subsequent S715, the head address of each track is stored in a “pointer variable (current reading position)” for each track. The above tempo value is a numerical value represented by BPM (Beat Per Minute). The pointer variable mentioned above is a variable for setting the head address of each track as a read position for each track in all tracks.

  In subsequent S717, the contents of the effect initial value table (see FIG. 9B) are set in the current effect table (see FIG. 9A). That is, the current effect table is initialized.

In subsequent S720, initialization processing is executed for parameters relating to performance such as sound source settings and reverb values.
In subsequent S725, the current step value is set to zero, and a note-off table output process described later is executed (S730). Subsequently, the transmission target track is set as the first track (S735), and output processing of the transmission target track is executed (S740). The output process of the transmission target track will be described later.

In subsequent S745, the transmission target track is set to the next track.
In subsequent S750, it is determined whether or not all the tracks are the transmission target tracks. If it is determined that not all tracks are the transmission target tracks (S750: No), the process proceeds to S740 and the following processing is repeatedly executed. On the other hand, if it is determined that all tracks are transmission target tracks (S750: Yes), the process proceeds to S755.

In S755, the numerical value “1” is added to the current step value.
In S760, the process waits for one step. Then, the process proceeds to S765.
In S765, it is determined whether or not an instruction to stop the performance data is transmitted from the control unit 12. If it is determined that an instruction to stop playing the performance data is transmitted from the control unit 12 (S765: Yes), this process ends. On the other hand, if it is determined that the instruction to stop the performance data is not transmitted from the control unit 12 (S765: No), the process proceeds to S770.

  In S770, it is determined whether all tracks have reached the end of each track. If it is determined that all tracks have not reached the end of each track (S770: No), the process proceeds to S730 and the following processing is repeatedly executed. On the other hand, if it is determined that the end of each track has been reached for all tracks (S770: Yes), this process is terminated.

[Note-off table data output processing of voice control unit 24 of karaoke apparatus 1]
Below, the processing procedure of the note-off table data output process performed by the audio | voice control part 24 of the karaoke apparatus 1 is demonstrated based on the flowchart of FIG.10 (b), and Fig.10 (a). FIG. 10A is an explanatory diagram showing a MIDI data note-off table. This note-off table data output process is executed when the process proceeds to S730 in the performance process executed by the audio control unit 24.

First, in step S1110, the data reading target is set in the head table of the note-off table (see FIG. 10A).
In the subsequent S1120, the value “1” is subtracted from the “Wait step value” of the table set as the data reading target.

  In the subsequent S1130, it is determined whether or not the above-mentioned “Wait step value” is a numerical value “0”. If it is determined that the “Wait step value” is not the numerical value “0” (S1130: No), the process proceeds to S1150 described later. On the other hand, when it is determined that the above-mentioned “Wait step value” is a numerical value “0” (S1140: Yes), a note-off of a table set as a data reading target is output (S1140), and the process proceeds to S1150. Transition.

In S1150, the table set as the data reading target is changed to the next table.
In subsequent S1160, it is determined whether or not all the tables have been confirmed. If it is determined that all the tables have not been confirmed (S1160: No), the process returns to S1120 and the processes in and after S1120 are repeatedly executed until the confirmation for all the tables is completed. On the other hand, if it is determined that all the tables have been confirmed (S1160: Yes), this process ends.

[Transmission target track output processing of voice control unit 24 of karaoke apparatus 1]
Below, the process sequence of the transmission target track output process performed by the audio | voice control part 24 of the karaoke apparatus 1 is demonstrated based on the flowchart of FIG. This transmission target track output process is executed when the process proceeds to S740 in the performance process of the audio control unit 24.

  First, in step S805, it is determined whether or not the performance has reached the end of the track in the transmission target track. If it is determined that the performance has reached the end of the track (S805: Yes), this process is terminated. On the other hand, if it is determined that the performance has not reached the end of the track (S805: No), the process proceeds to S810.

In S810, the numerical value “1” is subtracted from the delta time of the current reading position data (current position data).
In subsequent S815, it is determined whether or not the delta time of the current position data is a numerical value “0”. When it is determined that the delta time of the current position data is not the numerical value “0” (S815: No), this process is terminated. On the other hand, when it is determined that the delta time of the current position data is a numerical value “0” (S815: Yes), the process proceeds to S817.

  In S817, it is determined whether there is a change in the guide melody. Specifically, in S620 of the main process of the previous voice control unit 24, the determination is made with reference to the determination result as to whether or not an instruction to change the guide melody is transmitted from the control unit 12. If an instruction to change the guide melody is transmitted from the control unit 12 (S817: Yes), it is determined that the guide melody has been changed, and the process proceeds to S820. On the other hand, if an instruction to change the guide melody has not been transmitted from the control unit 12 (S817: No), it is determined that there is no change in the guide melody, and the process proceeds to S825 without executing S820.

In S820, it is determined whether or not the attribute of the track is a guide melody. If it is determined that the attribute of the track is not a guide melody (S820: No), a tone color non-change output process is executed (S825), and the process proceeds to S885 described later. On the other hand, if it is determined that the attribute of the track is a guide melody (S820: Yes), the process proceeds to S830.

In S830, a “timbre prefetching process” for examining the transition of the timbre in the track is executed.
In subsequent S835, it is determined whether or not the timbre in the track is a vibraphone. If it is determined that the tone color of the track is not a vibraphone (S835: No), the process proceeds to S825. On the other hand, if it is determined that the tone color of the track is vibraphone (S835: Yes), the process proceeds to S840.

  In S840, it is determined whether or not the read data is data indicating a note. If it is determined that the read data is data indicating a note (S840: Yes), a note output process described later is executed (S845), and the process proceeds to S885 described later. On the other hand, when it is determined that the read data is not data indicating a note (S840: No), the process proceeds to S850.

  In S850, it is determined whether or not the read data is data indicating either the timbre MAP or the timbre BANK. If it is determined that the read data is data indicating either the timbre MAP or the timbre BANK (S850: Yes), the parameter of the data at the current position is replaced with the specified value and is stored in the work area 24g of the RAM 24d. Store (S855), and go to S885 described later. On the other hand, if it is determined that the read data is not data indicating either the tone color MAP or the tone color BANK (S850: No), the process proceeds to S860.

  In S860, it is determined whether or not the read data is data relating to tone color settings. If it is determined that the read data is not data related to timbre settings (S860: No), the process proceeds to S870 described later. On the other hand, if it is determined that the read data is data related to tone color setting (S860: Yes), the process proceeds to S861.

In S861, the parameter of the data at the current position is replaced with the specified value and stored in the work area 24g of the RAM 24d.
In subsequent step 862, it is determined whether or not the previously substituted reverb setting value has been output. If it is determined that the previously substituted reverb setting value has been output (S862: Yes), the process proceeds to S864 described below. On the other hand, if it is determined that the previously substituted reverb setting value has not been output (S862: No), the reverb setting value is newly set to the specified value and stored in the work area 24g of the RAM 24d (S863). The process proceeds to S864.

  In S864, it is determined whether or not the previously replaced vibrato set value has been output. When it is determined that the previously replaced vibrato set value has been output (S864: Yes), the process proceeds to S885 described later. On the other hand, if it is determined that the previously replaced vibrato set value has not been output (S862: No), the vibrato set value is newly set to the specified value and stored in the work area 24g of the RAM 24d (S865). The fact that the timbre has been changed is stored in a built-in RAM or the like (S866), and the process proceeds to S885 described later.

  In S870, it is determined whether the read data is one of a reverb set value and a vibrato set value. If it is determined that the read data is not one of the reverb setting value and the vibrato setting value (S870: No), the data at the current position is stored in the work area 24g of the RAM 24d as it is (S880), and S885 described later. Migrate to On the other hand, when it is determined that the read data is either the reverb setting value or the vibrato setting value (S870: Yes), the parameter value is set for the corresponding effect area of the current effect table (S871). The parameter of the current position data is replaced with the specified value and stored in the work area 24g of the RAM 24d (S872), and the fact that the corresponding setting has been replaced is stored in the work area 24g of the RAM 24d (S874). Then, control goes to S885.

In S885, the data reading position is advanced by one step. Then, the process proceeds to S815 and the following processing is repeatedly executed.
[effect]
Thus, according to the karaoke apparatus 1 of the embodiment, the following effects can be obtained. That is, when the change data is acquired by the CPU 24e, the type of timbre of the effective guide melody and the setting information regarding the effective guide melody are stored in the setting content storage area 24i of the RAM 24d, and then the release data is stored by the CPU 24e. If acquired, the "tone color type data" and "setting data" are read from the setting content storage area 24i of the RAM 24d, and the read tone type data and setting data are inserted into the performance data stored in the work area 24g of the RAM 24d. Thus, the performance data is updated (see FIG. 4). In other words, when changing the timbre type of the guide melody, the timbre type of the effective guide melody and the corresponding setting contents are stored, and then the melody type of the guide melody is returned to the type before the change. At this time, the melody type of the guide melody is changed again based on the stored timbre type of the guide melody and various corresponding settings. As a result, the performance data includes data indicating the timbre setting of the guide melody multiple times, and the timbre type before the change after the melody type of the guide melody is changed from the change target timbre to the change non-target timbre Even when the setting is restored, it is possible to prevent a difference between the various settings related to the guide melody in the original change target tone color and the various settings related to the guide melody in the change target tone after the return.

  (2) Moreover, according to the karaoke apparatus 1 of the first embodiment, the CPU 24e acquires all performance data scheduled to perform a karaoke performance from the HDD 16 by the control unit 12 and temporarily stores it in the work area 24g. Change data and release data are detected from the performance data stored in the work area 24g. As a result, the activation frequency of the change data / cancellation data detection process described above can be reduced, and the processing load on the change data / cancellation data acquisition process in the CPU 24e can be reduced. Further, if the above-described processing is executed for a reserved song, the above-described processing can be performed during the performance of a performance song reserved before the reserved song. However, in order to temporarily store all performance data scheduled to perform karaoke performance in the work area 24g, it is necessary to increase the capacity of the storage area of the work area 24g.

  (3) Also, according to the karaoke apparatus 1 of the first embodiment, the CPU 24e detects an area where there is no effective note-on signal of the guide melody in the performance data as a “data insertable area”. As a result, the tone and sound settings are changed after the note-on signal of all the sounds that make up the chord of the guide melody is invalidated, so even if the chord is included in the guide melody, for example, It is possible to prevent the timbre and sound settings from being changed during performance to give a sense of incongruity.

[Other Embodiments]
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, It is possible to implement in the following various aspects.

  (1) In the first embodiment, the CPU 24e acquires performance data scheduled to perform karaoke performance from the HDD 16 by the control unit 12, temporarily stores it in the work area 24g, and the performance data stored in the work area 24g. However, the present invention is not limited to this. For example, the change data or the release data input from the operation unit 18 or the remote control terminal 2 included in the karaoke apparatus 1 may be acquired.

  (2) In the first embodiment, an area where there is no valid note-on signal of the guide melody in the performance data is detected as the “data insertable area”. An area between the off signal and the note on signal may be detected as a “data insertable area”.

  (3) In the first embodiment, when the CPU 24e inserts change data, release data, and setting data into the data insertable area, the note-on signal whose transfer timing is delayed among the note-on signals included in the performance data. If there is a data, detect other data insertable areas other than the data insertable area from the performance data, and insert part of the change data, release data, and setting data into the detected other data insertable areas. By doing so, the performance data stored in the work area 24g may be updated. In this way, if other data insertable areas are detected and part of the change data and setting data is inserted, note-on included in the performance data at the time of insertion of change data or the like into the data insertable area as described above The delay in signal transfer timing can be prevented, and the influence on the sound quality of the karaoke performance caused by the delay in the transfer timing of the note-on signal can be suppressed as much as possible.

  (4) In the first embodiment, while the CPU 24e acquires performance data scheduled to perform karaoke performance from the HDD 16 and temporarily stores it in the work area 24g of the RAM 24d, the work area 24g stores it. Change data and release data may be detected from the performance data. In this way, the capacity of the storage area of the work area 24g of the RAM 24d can be reduced. However, the execution frequency of the change data / release data detection process increases, and the processing load of the change data / release data acquisition process execution area in the CPU 24e increases.
