Description

  The present invention relates to a technique for guiding the performance of music performed by operating the performance operators constituting the performance operator group.

  There is a performance guide device that supports the performance of music performed by operating a group of performance operators such as a keyboard. The performance guide device is usually a visual user who uses at least one of a performance operator to be operated sequentially and a finger (fingering) recommended to be used for operation of the performance operator as the performance progresses. By notifying the system, it helps to perform the correct operation.

  The performance guide by the performance guide device is usually performed in units of music, that is, through the music from the beginning to the end. However, when guiding is performed consistently in this way, that is, for each performance operator to be operated at all times, notification of the performance operator or fingering (performance operation information) is given, and the user relies on the guide. The practice efficiency tends to be low. For this reason, in a conventional performance guide device, as described in Patent Document 1, a performance operator (musical tone) to be operated as to whether or not to perform fingering display (instruction) as a performance guide is described. There is one which is set every time and the fingering display is performed according to the setting. In the performance guide device, whether or not the operation of the performance operator is appropriately performed is monitored, and the setting is changed in accordance with the monitoring result, so that the performance operator that the user has not been able to perform the appropriate operation can be obtained. The fingering display can be performed only for the operation.

  Since the fingering display and notification of the performance operator to be operated must be performed in accordance with the progress of the performance, the performance guide itself is executed regardless of whether or not the notification is performed. For this reason, guides by fingering display or performance operator notification are collectively referred to as “guide display”, and guides executed to perform the guide display are simply referred to as “guides”.

  It should be noted that the difficulty level of performance is not always the same level for the entire music. Usually, the difficulty is uneven. For this reason, some conventional performance guide devices, as described in Patent Document 2, can guide only a part of music.

A user (performer) who is inexperienced in performance techniques cannot always properly perform operations on the performance operators that can be appropriately operated during the performance even in the next performance. Since importance was placed on the part that could not be played properly, it may not be possible to play the part that has been played properly in the past. For this reason, it is very difficult to accurately predict in advance a portion that requires guide display. As a result, it is considered important for the performance guide to ensure that the guide display required by the user can be implemented.
Japanese Patent Laid-Open No. 10-207346 JP 60-25790 A

  An object of the present invention is to provide a performance guide apparatus that can reliably perform guide display required by a user during performance.

The performance guide device of the present invention is based on the premise of guiding the performance of music performed by operating the performance operators constituting the performance operators, and the performance operators to be operated in the performance operators, And notification means for notifying the user as performance operation information of at least one of fingers recommended for operation on the performance operator, and the performance operation information sequentially according to the progress of the performance of the music , Information storage means for storing a plurality of types of performance guide information for notification for each same music piece, and one of a plurality of types of performance guide information stored in the information storage means for the progress of the performance of the music piece The performance guide means capable of notifying the performance operation information via the notification means by processing together, and the performance guide means using the performance guide information, the performance guide means If you are performing a predetermined time performance operators became timing for operation among the performance operator group, if the user does not operate, the performance guide information to be processed by said performance guide means a guide control means for switching to a different performance guide information, by the guide control means, when said performance guide information to be processed by said performance guide means is switched to another performance guide information, said performance guide means to process By changing the processing position before the processing position, the contents after the processing position processed by the performance guide means are changed, and the performance operation information is notified to the performance guide means with the changed contents. And a processing position changing means for performing the processing.

Program of the present invention is to have a computer capable of using as a performance guide device for guiding the playing of the music to be performed by the operation of the performance operators which constitutes a performance operation element group, for realizing the performance guide device It has a function.

  In the present invention, when the performance guide means guides using the performance guide information, at least one of the user's operation to the predetermined operation element and the user's operation to the performance operation group is determined. Based on the information, the contents after the position in the performance guide information are changed, and the guide notification for notifying the performance operation information with the changed contents is performed. In this way, the performance location where the guide notification (performance operation information notification) is performed is limited to the portion that the user feels necessary. Therefore, it is possible for the user to perform a performance supported by the guide notification that is considered necessary while suppressing the reliance on the guide notification. As a result, more efficient performance practice can be performed.

  In the present invention, the content of the processing position in the performance guide information is changed by the user's operation to one or more instruction operators for instructing to change the content of the performance guide information. For this reason, it is possible to limit the performance location where the guide notification is performed to the portion where the user feels necessary. Thereby, the same effect can be acquired. The change is limited to the case where the guide is performed using the performance guide information, so that the user can appropriately make the change felt necessary in the performance flow.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a configuration diagram of an electronic musical instrument equipped with a performance guide device according to the first embodiment.
As shown in FIG. 1, the electronic musical instrument includes a CPU 101 that controls the entire musical instrument, a program executed by the CPU 101, music data for performance guide (performance guide data), and a program-ROM that stores various control data. (Hereinafter referred to as “ROM”) 102, work-RAM (hereinafter referred to as “RAM”) 103 used by CPU 101 for work, a keyboard (performance operator group) 104 for performance by the user, and switches (SW) comprising various switches. A group 105, an interface group 106 including a plurality of interfaces for detecting operations performed on the keyboard 104 or the switch group 105, a display device 107 that can be used as a performance guide, and the display device 107 Interface 108 for displaying images and waveform data for musical sound emission A W-ROM 109, a sound source 110 for generating waveform data of a musical sound to be emitted using the waveform data stored in the W-ROM 109, and waveform data output from the sound source 110 as analog waveform signals (audio signals). A D / A converter (DAC) 111 that converts the signal to the audio signal output from the DAC, an address bus 121 that interconnects the units 101 to 103, 106, 107, and 110, and And a data bus 122.

  FIG. 2 is a diagram showing a performance guide performed through the display device. As shown in FIG. 2, in the performance guide, musical notes (corresponding to keys to be operated (performance operators)) to be emitted by the right hand and left hand, respectively, and operation of the keys (key pressing) A finger (fingering) recommended for use as a performance operation information can be visually notified (guide display) to the user (performer).

  In the present embodiment, although not particularly illustrated, a keyboard 104 in which LEDs are arranged for each key is employed. As a result, the key to be operated can be visually notified to the user by turning on the LED corresponding to the key. The LED is turned on / off via the drive interface that constitutes the interface group 106. For this reason, the performance guide apparatus according to the present embodiment is realized by a configuration excluding the W-ROM 109, the sound source 110, the DAC 111, and the speaker 111. The performance information as shown in FIG. 2 can be displayed on the display device 107, and the keyboard 104 is provided with an LED for each key. Therefore, at least one of the key to be operated and the fingering is visually displayed. The guide can be displayed by notifying the user.

  FIG. 3 is a diagram showing performance guide data stored in the ROM 102 and the RAM 103, respectively. 3A shows the data stored in the ROM 102, and FIG. 3B shows the data stored in the RAM 103. As shown in FIG. 3A, the ROM 102 has an area for storing an original guide DB (database) and a remind guide DB. In one RAM 103, as shown in FIG. 3B, an area (area) for storing the user guide DB and temp guide data is secured.

  FIG. 4 is a diagram illustrating a data configuration of the original guide DB. This DB is constructed in order to manage original music data for each music. In FIG. 4, “(1)” appended in parentheses after “music data” like “music data (1)” indicates that the music number assigned to the music data is 1. The music data is data for executing the performance guide. As shown in FIG. 4, the music data itself includes time data indicating the timing at which the event should be generated for each performance event, and an event indicating the event content. Data (hereinafter, collectively referred to as “guide display data”) is collected and arranged in order from the earliest timing at which the collected data should be generated. The time data is data indicating the time (delta time) since the last guide display data was processed. It is assumed that the time data and event data are stored at one address.

  If the performance event is a tone production (start) of the musical sound, the event data is the type of the event (indicated as “ON” in the figure), the pitch of the musical sound, for example, a key number indicated as “NOTE in the figure”. ) And velocity data indicating the volume of the musical sound to be emitted. If the sound is muted, the event type (indicated as “OFF” in the figure), the pitch of the musical sound (NOTE), and the implementation guide (indicated as “yz” in the figure) are provided. . Hereinafter, the former is referred to as “note-on event data”, and the latter is referred to as “note-off event data”.

  The implementation guide data indicated by “yz” is for designating the content of the guide to be actually displayed. “Y” indicates guide content data for specifying the content, and “z” indicates fingering data. The fingering data z is an integer value between 1 and 10, with 1 to 5 indicating the left hand finger and 6 to 10 indicating the right hand finger. 1 and 6 indicate thumbs, and 5 and 10 indicate pinkies. Guide content data y is an integer value between 1 and 4, 1 does not display both the key and fingering guide, 2 displays only the fingering guide, 3 displays only the key guide, 4 indicates the key Instructs the contents of the performance guide to display the guide for both fingering and fingering. As a result, the music data has a guide display to be performed during performance (guide) set in advance for each musical tone (key). The fingering data is also referred to as a finger number.

  The music data stored in the original guide DB is intended for performers who have a certain level of performance skills. The remind guide DB stores song data created assuming a performer with a very low performance technique. Thus, in the present embodiment, guide display using song data stored in the remind guide DB can be temporarily performed as necessary during performance.

  In the performance guide based on the music data of the remind guide DB, the LED (key) is turned on or the fingering display (FIG. 2) is performed except for pressing the key that can be operated very easily. For this reason, the user can temporarily perform only the guide display required at that time by switching to the performance guide based on the music data. In this way, only the necessary guide display is temporarily performed, so it is possible to avoid performing too much on the guide display, and perform on the guide display where it is necessary to rely on the guide display. Can do. As a result, the performance practice can be performed more efficiently than when the guide display is always performed.

  The portion of the music that is difficult to play may vary from user to user. This means that the part that the guide display is necessary differs depending on the user. For this reason, in the present embodiment, song data capable of displaying a guide desired by the user can be generated. The generation is performed by updating the original music data. An area for storing temp guide data (temp guide data area) secured in the RAM 103 is used for updating the area. The music data after the update is stored in the user guide DB. For this reason, the song data itself has the same configuration regardless of the DB or area in which it is stored.

  The music data stored in the user guide DB is likely to be able to display a guide more appropriate for the user than the original music data. For this reason, in the present embodiment, priority is given to data stored in the user guide DB as music data of music to be played.

  The performance guide is started by a start instruction as in normal automatic performance, and is performed by sequentially processing guide display data according to the time data of the guide display data. The song data is updated during the performance guide. This is to ensure that the guide display felt necessary during the performance can be performed. Thereby, the guide display by the song data in the user guide DB can surely perform only what the user thinks is necessary during the performance. A performance guide using such song data allows the user to practice more efficiently.

  The selection of the music data, that is, the input of the music number is performed by operating the music selection switch constituting the switch group 105. A plurality of music selection switches are arranged to enable input of music numbers of two digits or more. In addition to this, as a switch related to the performance guide, a start / stop switch for instructing start / stop of the performance guide, a guide display setting switch for instructing correction to perform the guide display, and the guide display A guide erasure setting switch for instructing correction not to be performed, a fingering change switch for instructing change of fingering display, a remind switch for instructing temporary implementation of guide display, and the like are provided. . A performance guide that temporarily uses music data in the remind guide DB is performed by operating a remind switch.

  It is not necessary to provide all the various switches. For example, there are a plurality of fingering change switches so that a fingering display change can be instructed for each finger, like the music selection switch. Both of these switches can be replaced by a numeric keypad that changes the function assignment. However, here, in order to avoid confusion, the description will be made on the assumption that all the above-mentioned various switches exist.

  For example, the interface for the switch group 105 of the interface group 106 scans each switch constituting the switch group 105 and analyzes the scan result to identify the switch whose state has changed and the content of the state change. The CPU 101 is notified of the identification result. Similarly, the interface for the keyboard 104 identifies the key whose state has changed, the contents of the state change (including velocity if the key is changed), and notifies the CPU 101 of the identification result. As a result, the CPU 101 controls the entire musical instrument according to the user's operation on the switch group 105, and performs control for generating a musical sound according to the operation on the keyboard 104. Such control is realized by the CPU 101 executing a program read from the ROM 102.

  The sound generation / mute is performed by sending a command to the sound source 110. In response to the command input from the CPU 101, the tone generator 110 starts or ends the generation of the waveform data of the musical sound to be generated using the waveform data stored in the W-ROM 109. The generated waveform data is output to the DAC 111. By inputting the waveform data to the DAC 111, an audio signal is output from the DAC 111 to the speaker 112, and a musical sound is emitted.

  The CPU 101 performs the following process by executing the above program, thereby realizing a performance guide using music data. This will be specifically described with reference to flowcharts of various processes shown in FIGS.

FIG. 5 is a flowchart of the entire process. First, the entire process will be described in detail with reference to FIG.
First, in step SA1, initialization is performed by turning on the power. In the subsequent step SA2, a switch process for responding to a user operation on the switch group 105 is executed. Thereafter, the guide process for performing the performance guide in step SA3, the keyboard process for responding to the user's operation on the keyboard 104 in step SA4, and the other processes in step SA5 are executed, and then the above steps Return to SA2. Thereby, while the power is on, the processing loop formed in steps SA2 to 5 is repeatedly executed to operate in response to the user's instruction. Transmission / reception of MIDI data via a MIDI terminal (not shown) is realized by executing the process of step SA5.

Hereinafter, a subroutine process executed in the overall process will be described in detail.
FIG. 6 is a flowchart of the switch process executed as step SA2. In the subroutine processing, the switch processing will be described in detail with reference to FIG.

  First, in step SB1, a music selection switch process is performed in response to an operation on the music selection switch. After that, after executing processing for corresponding operations to the start / stop switch, guide display setting switch, guide erasing setting switch, fingering change switch, remind switch, and other switches in steps SB2 to SB7, respectively. This switch processing is terminated.

In steps SB1 to SB6, the following subroutine processing is executed. This will be described in detail with reference to FIGS.
FIG. 7 is a flowchart of the music selection switch process executed as step SB1. In the subroutine process executed in the switch process shown in FIG. 6, the song selection switch process will be described in detail with reference to FIG.

  As described above, there are a plurality of song selection switches, and one or more song selection switches are operated to select a song, that is, to input a song number. However, for the sake of convenience, a detailed description of portions corresponding to such operations will be omitted here.

  First, in step SC1, it is determined whether or not the value of the variable STF is zero. The variable STF is a variable for managing whether or not the performance guide is being used, and 1 as an assigned value indicates that the performance guide is being used, and 0 as a value indicates that the performance guide is not being used. Yes. For this reason, if the performance guide is not being used, the determination is yes and the process proceeds to step SC2, and if not, the determination is no and the song selection switch process ends here.

  In step SC2, it is determined whether or not the music selection switch is turned on. When the switch is operated by the user, the CPU 101 is notified from the interface for the switch group 105 of the interface group 106, so the determination is YES, and the variable M is set to the variable M in step SC3 by the operation of the song selection switch. After the input music number is substituted, the process proceeds to step SC4. Otherwise, the determination is no and the song selection switch process is terminated here.

  In step SC4, it is determined whether or not there is music data ("music [M] data" in the figure) whose music number is the value of the variable M in the user guide DB. If the song data does not exist, the determination is YES, and in step SC5, the song data in which the song number in the original guide DB is the value of the variable M is read and copied into the user guide DB. After the song data whose number is the value of the variable M is copied into the temp guide data area, the song selection switch process is terminated. On the other hand, when that is not right, determination is NO and it transfers to step SC6 next.

  In this manner, when the song selection switch is operated in a situation where the performance guide is not performed, it is assumed that the user has selected a song, and the song data of the song number input for the selection is displayed as the temp guide. Prepared in the data area. As the song data to be copied to the area, priority is given to the user guide DB, but the user may be able to select the DB in which the song data to be copied is stored.

  FIG. 8 is a flowchart of the start / stop switch process executed as step SB2 in the switch process shown in FIG. Next, the switch processing will be described in detail with reference to FIG.

  First, in step SD1, it is determined whether or not the start / stop switch is turned on. If the switch is operated by the user, the determination is yes, and the value of the variable STF is inverted at step SD2, that is, if the value is 1, it is updated to 0 if the value is 0, and then to step SD3. Transition. If not, the determination is no and start here. Stop switch processing ends.

  In step SD3, it is determined whether or not the value of the variable STF is 1. If the value is 0, the determination is no and the process proceeds to step SD12, and if not, the determination is yes and the process proceeds to step SD4.

  In step SD4, the value of the start address of the song data to which the value of the variable M is assigned as the song number in the user guide DB is substituted into the variable AD1. In the subsequent step SD5, the value of the start address of the temp guide data area is substituted for the variable AD2. In the next step SD6, the value of the start address of the music data to which the value of the variable M is assigned as the music number of the original guide DB is substituted into the variable AD3. In this way, from the song data of the same song number stored in the user guide DB, the temp guide data area, and the remind guide DB so that the song data used for the performance guide can be switched and the song data can be updated. After preparing to read data or write data by substituting initial values for the variables AD1 to AD3, the process proceeds to step SD7.

  In step SD7, data stored in the address designated by the value of the variable AD2 in the temp guide data area (here, time data as shown in FIG. 4) is read. At the next step SD8, the read time data is substituted into the variable T. Thereafter, in step SD9, 0 and 1 are substituted for variables n and m, respectively, and in step SD10, execution prohibition of the timer interrupt processing for timing for determining the arrival of the processing timing of the event data is canceled, and further in step SD11 Then, after substituting 0 into the variable ONF, the start / stop switch process is terminated.

  The timer interrupt process is started by an interrupt signal generated at a time interval corresponding to the minimum time resolution of the time data, and the value of the variable T is decremented each time it is started. Therefore, the value of 0 indicates the arrival of processing timing. The prohibition of execution is performed by enabling the interrupt signal. Conversely, the prohibition is performed by invalidating the interrupt signal. The variables n and m are mainly used for designating an address for reading data from the music data. The variable ONF is prepared for determining the presence / absence of a key to be operated, and a substituted value of 0 indicates that such a key does not exist, and a value of 1 indicates that it exists. It is shown that.

  In step SD12 in which the determination in step SD3 is NO and the process proceeds to step SD12, the interface 108 and the corresponding interface of the interface group 106 are instructed to end all the performance guide displays. In the subsequent step SD13, execution of the timer interrupt process is prohibited, and in step SD14 to which the process proceeds thereafter, the user is inquired whether or not the song data in the temp guide data area is to be overwritten and saved in the user guide DB, and the user by the inquiry Overwrite according to the instructions. If the save is not instructed, the song data is simply discarded. The start / stop switch process ends after such a thing is performed.

  FIG. 9 is a flowchart of the guide display setting switch process executed as step SB3 in the switch process shown in FIG. Next, the switch processing will be described in detail with reference to FIG.

  In the present embodiment, as described above, guide display is performed according to the implementation guide data inserted in the music data. As a result, the guide display is not always performed at the portion where the user desires the guide display. For this reason, this guide display setting switch is provided so that the guide display can be actually performed at a portion (performance part) where it is desired to perform the guide display.

  First, in step SE1, it is determined whether or not the value of the variable STF is 1. If the value is 1, that is, during the performance guide, the determination is yes and the process proceeds to step SE2. Otherwise, the determination is no and the guide display setting switch process is terminated here.

  In step SE2, it is determined whether the guide display setting switch is turned on. If the user operates the switch during the performance guide, the determination is yes, and after setting 1 to the variable GON in step SE3, the setting switch process is terminated. Otherwise, the determination is no and the setting switch process ends here.

  Thus, in this embodiment, the operation to the guide display setting switch is valid only during the performance guide. Thus, the music data stored in the temp guide data area is changed so that guide display is performed at the place where the setting switch is operated during the performance guide. 1 assigned to the variable GON is a value indicating that the guide display setting switch has been operated, and 0 is normally assigned.

  As described above, the guide erasure setting switch is a switch provided so that the guide display is not actually performed in a portion where it is not desired to perform the guide display, and the remind switch can temporarily perform the guide display. The switch and fingering change switch provided in this manner are switches provided so that the fingering display can be changed. Similar to the guide display setting switch, these switches are valid only during the performance guide, and 1 is assigned to the variables GOFF, REMINDF, and CHGF, respectively, by the operation during the performance guide. In the operation on the fingering change switch, the finger number assigned to the operated fingering change switch (an integer value between 1 and 10 as described above) is substituted into the variable FINGER.

  For this reason, as shown in FIGS. 10 to 12, the flowchart of each subroutine process executed as steps SB4 to SB6 in the switch process of FIG. 6 in order to respond to the operations on them is shown in step SB5. The fingering change switch process is basically the same except that a process step for assigning a finger number to the variable FINGER is added. Accordingly, detailed description of these subroutine processes will be omitted.

Returning to the description of the subroutine processing executed in the overall processing shown in FIG.
13 to 17 are flowcharts of the guide process executed as step SA3. Next, the guide processing will be described in detail with reference to FIGS.

  First, in step SI1, it is determined whether the value of the variable STF is 1. If the value is 1, the determination is yes and the process proceeds to step SI2, and if not, the determination is no and the guide process ends here.

  In step SI2, it is determined whether the value of the variable ONF is 0, that is, there is no key to be pressed. If there is no key to be pressed, the determination is yes and the process proceeds to step SI3, and if not, the determination is no and the process proceeds to step SI32 in FIG.

  In step SI3, it is determined whether or not the value of the variable T is 0 or less. When the value is 0 or less, that is, when the timing for processing the event data in the guide display data obtained by substituting the time data for the variable T has arrived, the determination becomes YES, and the value of the variable n is incremented and advanced in step SI4. Further, in step SI5, the data stored in the address specified by the addition result of the value of the variable AD2 and the value of the variable n in the temp guide data area is read, and then the process proceeds to step SI6. Otherwise, the determination is no and the guide process ends here.

  In step SI6, it is determined whether or not the read data indicates the end of the song data (denoted as “END” in the figure). If it indicates the end, the determination is YES, 0 is substituted into the variable STF in step SI7, all the guide displays being displayed are terminated in step SI8, and the song data in the temp guide data area is further displayed in step SI9. Is overwritten and saved in the user guide DB, and overwritten in accordance with the user's instruction in response to the inquiry, the guide process is terminated. Otherwise, the determination is no and the process moves to step SI10.

  In step SI10, it is determined whether or not the read data is time data. If the time data is read, the determination is yes, and after the time data is substituted into the variable T in step SI11, the guide process is terminated. Otherwise, the determination is no and the process moves to step SI12 in FIG.

  In step SI12, it is determined whether or not the read data is note-off event data. If the event data is read, the determination is YES, the LED of the key corresponding to the pitch (NOTE) data in the event data is turned off in step SI13, and 0 is substituted into the variable ONF in step SI15. Returning to step SI4 of FIG. Otherwise, the determination is no and the process moves to step SI16 in FIG.

  In step SI16, it is determined whether or not the read data is note-on event data. If the event data has not been read, the determination is no, and after processing for responding to other event data is executed in step SI17, the process returns to step SI4 in FIG. Otherwise, that is, when note-on event data is read out, the determination is YES, and pitch data (denoted as “note” in the figure) in the event data is substituted into the variable NOTE in step SI18. After substituting 1 for the variable m in step SI19, the process proceeds to step SI20.

  In the present embodiment, as shown in FIG. 4, the implementation guide data is inserted into the note-off event data. This is because the storage space for velocity data that is unnecessary in the note-off event data is effectively used. In steps SI20 to SI23, processing for reading note-off event data corresponding to the read note-on event data is performed while sequentially incrementing the value of the variable m.

  First, in step SI20, data is read from an address designated by the addition result of each value of variables AD2, n, and m in the temp guide data area. In the next step SI21, it is determined whether or not the read data is note-off event data. If the read data is not the event data, the determination is no, the value of the variable m is incremented in step SI22, and the process returns to step SI20. Otherwise, the determination is yes and the process moves to step SI23.

  In step SI23, it is determined whether or not the pitch data value (key number) in the note-off event data is equal to the variable note value. If these values are not equal, the determination is no, and the routine proceeds to step SI22 where the value of the variable m is incremented. Otherwise, if the note-off event data corresponding to the note-on event data read in step SI5 in FIG. 13 can be read, the determination is yes and the process moves to step SI24.

  In step SI24, implementation guide data yz is extracted from the event data read in step SI20. After the extraction, the process proceeds to step SI25 to determine whether or not the value of the guide content data y is equal to one of 3 and 4. If the value is 3 or 4, the determination is yes and the process proceeds to step SI26. Otherwise, the determination is no and the process moves to step SI31.

  In step SI26, the LED of the key to which the value (key number) of the variable NOTE is assigned is turned on. In a succeeding step SI27, it is determined whether or not the value of the guide content data y is 4. If the value is 4, the determination is YES, and in step SI28, a fingering recommended for pressing the key to be pressed is displayed according to the fingering data z (FIG. 2), and the variable N is displayed in step SI29. Substituting the addition results of the variables n and m, substituting 1 for the variable ONF in step SI30, and then returning to step SI4 in FIG. Otherwise, the determination is no and the process moves to step SI29.

  On the other hand, in step SI31, it is determined whether or not the value of the guide content data y is 2. If the value is 2, the determination is yes and the process proceeds to step SI28. Otherwise, the determination is no and the process moves to step SI29.

In this way, the guide display is performed according to the guide content data y by executing the processes of steps SI25 to SI28 and SI31.
In step SI32 in FIG. 16 in which the determination in step SI2 in FIG. 13 is NO and the process proceeds, it is determined whether or not the value of the variable REMINDF is 1. When the user operates the remind switch, since the value is 1, the determination is YES, and the process proceeds to step SI33. Otherwise, the determination is no and the process moves to step SI42.

  In step SI33, data is read from the address specified by the addition result of the values of the variables AD3 and N of the music data assigned with the value of the variable M as the music number in the remind guide DB. After reading, the process proceeds to step SI34. The details of the processing executed at each step of steps SI34 to SI39 are basically the same as steps SI24 to SI28 and SI31 of FIG. By executing the processing of these steps, performance guides based on the song data in the remind guide DB are performed, and guide display assuming a user who is inexperienced in performance techniques is performed. The process proceeds to step SI40 by determining NO in step SI37 or SI39 or executing the process in step SI38.

  In step SI40, execution of the timer interrupt process is prohibited. In the subsequent step SI41, 0 is substituted into the variable REMINDF. Thereafter, the process proceeds to step SI56 in FIG.

  Thus, in this embodiment, when the user operates the remind switch, only the guide display for one key press is performed. This is to surely avoid the guide display that the user does not want. This is the same for other switches, but guide display (change of music data) may be performed in units of a preset performance period (for example, one measure or a predetermined number of notes). With other switches, the song data is in line with the user's feeling that the guide display is necessary in the performance flow, the guide display is not required, or it is preferable to use a finger different from the finger displayed. This is because the emphasis was placed on making it easy and appropriate to change the above.

  In the present embodiment, the song data used for the performance guide is switched to cope with the operation of the remind switch. However, a predetermined guide display may be performed regardless of the guide content data y. .

  In step SI42, it is determined whether or not the value of the variable T is equal to or smaller than a predetermined value −α. If the user does not press the key for a certain time after the timing to press the key, the relationship is established and the determination is YES, and the process proceeds to step SI33. Otherwise, the determination is no and the process moves to step SI43.

  In this way, in the present embodiment, if the user does not press the key for a certain time after the timing to press the key, the same processing as when the remind switch is operated is executed. I have to. This is because the user could not press the key because it can be considered that a guide display is necessary for pressing the key.

  In step SI43, it is determined whether the value of the variable KEYONF is 1. The variable is for determining whether or not the user has newly pressed a key on the keyboard 104. 1 indicates that the key was pressed, and 0 indicates that the key was not pressed. Therefore, if the user has not pressed a new key, the determination is no and the process proceeds to step SI45 in FIG. Otherwise, the determination is yes and the process moves to step SI44.

  In step SI44, it is determined whether or not the value of the variable KEY is equal to the value of the variable NOTE. The variable is assigned with the key number assigned to the key newly pressed by the user. For this reason, when the user newly presses the key to be pressed, the determination is YES, and 0 is substituted for the variable ONF in step SI44a, and then the process returns to step SI4 in FIG. Otherwise, the determination is no and the process moves to step SI45 in FIG.

  In step SI45, it is determined whether or not the value of the variable GON is 1. If the value is 0, that is, if the user has not operated the guide display setting switch, the determination is no and the process moves to step SI48. Otherwise, the determination is yes and the process moves to step SI46.

  In step SI46, the data (note-off event data) is read from the address specified by the addition result of the values of the variables AD3 and N of the music data assigned with the value of the variable M as the music number in the remind guide DB. Is overwritten at the address designated by the addition result of the values of the variables AD2 and N in the temp guide data area. After the overwriting, 0 is substituted for the variable GON in step SI47, and then the process proceeds to step SI56.

  In step SI48, it is determined whether or not the value of the variable GOFF is 1. If the value is 0, that is, if the user has not operated the guide erase setting switch, the determination is no and the process moves to step SI52. Otherwise, the determination is yes and the process moves to step SI49.

  In step SI49, if the guide is being displayed, it is terminated. In subsequent step SI50, the execution guide data yz in the data (note-off event data) stored at the address specified by the addition result of the values of the variables AD2 and N in the temp guide data area is rewritten to “1z”. Accordingly, the execution guide data yz is changed so that the guide display is not performed. After such a change, 0 is substituted into the variable GOFF in step SI51, and then the process proceeds to step SI56.

  In step SI52, it is determined whether or not the value of the variable CHGF is 1. If the value is 0, that is, if the user has not operated the fingering change switch, the determination is no and the process returns to step SI4 in FIG. Otherwise, the determination is yes and the process moves to step SI53.

  In step SI53, if the fingering display is in progress, it is terminated. In the following step SI54, the execution guide data yz in the data (note-off event data) stored at the address specified by the addition result of the values of the variables AD2 and N in the temp guide data area is changed to only the fingering data. The value is rewritten to the value of FINGER (in the figure, the implementation guide data after rewriting is expressed as “y · FINGER”). After the rewriting, 0 is substituted for variable CHGF in step SI55, and then the process proceeds to step SI56.

  In step SI56, a value obtained by subtracting a predetermined value from the previous value is substituted for variable n. As a result, the position where the guide display should be performed is returned to the previous position. Thereafter, the process proceeds to step SI57, where data is read from the address specified by the addition result of the values of the variables AD2 and n in the temp guide data area, and it is determined whether or not the read data is time data. If the time data is read, the determination is yes and the process proceeds to step SI59. If not, the determination is no and the value of variable n is incremented in step SI58 and then the process of step SI57 is performed again. Execute.

  In step SI59, the read time data is substituted for variable T. In the next step SI60, 0 is substituted into the variable m. In the next step SI61, the prohibition of execution of the timer interrupt process is canceled. After the cancellation, the guide process is terminated.

  Thus, in this embodiment, when the user operates any one of the remind switch, the guide display setting switch, the guide deletion setting switch, and the fingering change switch, the performance guide is restarted from the position before that point. To do. This is because the user can immediately confirm whether or not the operation of these switches has been properly performed. By making the confirmation immediately, the confirmation can be performed more appropriately and easily for the user.

FIG. 18 is a flowchart of the keyboard process executed as step SA4 in the overall process of FIG. Finally, the keyboard process will be described in detail with reference to FIG.
First, in step SJ1, the keyboard 104 is scanned by the corresponding interface of the interface group 106, and the analysis result by the scanning is received. In the subsequent step SJ2, a change caused by the key on the keyboard 104 is determined based on the analysis result. If it is determined that the change does not occur in any key, the keyboard process is terminated here. If it is determined that a change due to key depression (ON) has occurred, the process proceeds to step SJ3.

  In step SJ3, the key number of the key that has changed due to the key depression is substituted into the variable KEY. In the next step SJ4, the velocity is substituted into the variable VELOCITY. In the next step SJ5, a command for instructing the tone generation of a musical tone is created using the values of the variables KEY and VELOCITY, and the created command is sent to the sound source 110 in the subsequent step SJ6. After the transmission, after assigning 1 to the variable KEYONF in step SJ7, the keyboard process is terminated. The values assigned to the variables KEY and VELOCITY are values present in the analysis result received from the interface.

  If it is determined in step SJ2 that a change due to the key release (OFF) has occurred, the process proceeds to step SJ8, and the key number of the key in which the change has occurred due to the key release is substituted into the variable KEY. In the next step SJ9, 0 is substituted for the variable VELOCITY. In the next step SJ10, a command for instructing to mute the musical tone is created using the values of the variables KEY and VELOCITY, and the created command is sent to the sound source 110 in the subsequent step SJ11. After the transmission, 0 is substituted for the variable KEYONF in step SJ12, and then the keyboard process is terminated. At this time, values to be substituted for the variables KEY and VELOCITY are also present in the analysis result received from the interface.

  In many cases, the user presses a plurality of keys on the keyboard 104 at the same time, or a key is pressed. However, in the above-described keyboard process (FIG. 18), in order to avoid confusion, the process executed on the assumption that only one key is pressed simultaneously by the user is described.

  In this embodiment, both the key to be pressed and the recommended finger for pressing the key can be displayed as a guide (can be notified as performance operation information), but only one of them is displayed as a guide. You may do it. The guide display can be temporarily performed by operating the remind switch, but conversely, the guide display may be specified so as not to be performed temporarily. By making such a designation possible, it becomes possible for a user (performer) to perform a performance without depending on the guide without depending on the guide. As a result, it is possible to respond to user requests from a different viewpoint. The above-mentioned method can be used for the realization. In the present embodiment, the present invention is applied to a performance guide device mounted on an electronic musical instrument, but the present invention may be applied to a dedicated device or a device mounted on another device.

  A program for realizing the performance guide apparatus as described above may be distributed by being recorded on a recording medium such as a CD-ROM, a DVD, or a removable flash memory. Part or all of the program may be distributed via a communication network such as a public network. In such a case, the user can apply the present invention to a computer by acquiring the program and loading it into a computer that can be used as a performance guide device. Therefore, the recording medium may be accessible by a device that distributes the program.
