Abstract

PROBLEM TO BE SOLVED: To provide the play guide device which give a variety of key depression guides without using any extra track and performing a special process such as prereading. SOLUTION: On a track where note data for generating a musical sound by driving a sound source are written, data for displaying keys to be pressed in advance for a key depression guide are composed of normal note-ON data and note-OFF data. Here, a velocity value is 1. When note data having a velocity of 1 is inputted (read out), the device regards the data as predictive display data and blinks a keyboard LED according to this data. Even when this data is read in the sound source as it is, the velocity is 1, so a musical sound of audible level is never synthesized and the note data can be used as illumination controlled data as it is.

Thus, the download is completed.

In FIG. 1, a keyboard 16 is connected to the detection circuit 15. The keyboard 16 has 61 keys (C1 to C
6), 76 keys (E0 to G6), or 88 keys (A-1 to
Any of C7) may be used. The keyboard LED 19a
Are provided for 61, 76 or 88 keys corresponding to the keyboard 16 to be used. A switch group 18 is connected to the detection circuit 17. The switch group 18 includes a play / stop switch 18a, a guide mode switch 18b, and the like. The display circuit 19 includes a display device that controls lighting of the keyboard LED 19a and displays a currently selected mode, tone color, and the like.
The sound source circuit 21 is connected to the effect circuit 22,
A sound system 23 is connected to the effect circuit 22.

When the key of the keyboard 16 is turned on, this ON event is detected by the detection circuit 15, and the key-on signal is
It is transmitted to PU10. The CPU 10 transmits the tone generation event data to the tone generator 21 in order to form a tone signal based on the key-on. The tone generator 21 forms a tone signal based on this data and outputs it to the effect circuit 22. The effect circuit 22 is a circuit for giving an effect such as reverb to a tone signal, and what effect is given and how much is set by parameters input from the CPU 10. The effect circuit 22 applies the above-described effect to the tone signal input from the tone generator 21 and then outputs the tone signal to the sound system 23. The sound system 23 amplifies this tone signal and outputs it as sound.

When the play / stop switch 18a is turned on, an automatic performance based on the data of the music specified at that time is started. When the play / stop switch 18a is turned on again, the automatic performance stops. This automatic performance can be performed using performance data received in real time from an external device via the interface 14, or can be performed by reading performance data stored in the external storage device 13 of the device. it can.

When the guide mode is turned on by operating the guide mode switch 18b during the automatic performance, the key press guide function is turned on. The key press guide turns on / off a keyboard LED 19a provided on the keyboard 16 in accordance with the progress of the automatic performance, and instructs the player which key to turn on. This key pressing guide is usually executed for a key that plays a melody. At the key-on timing, the LED corresponding to the key is turned on in the second mode, and the LED is turned on in the first mode a predetermined time before the key-depression timing. By this first lighting, the user can immediately know that the key is depressed. In this embodiment, the lighting of the first mode is a constant lighting method, and the lighting of the second mode is a lighting method of blinking at short intervals (about several hundred milliseconds). As described with reference to FIGS. 3 (A) and (B), this advance notice lighting is a method of lighting the key until the key is pressed after the key is turned off. Various methods can be adopted, such as a method of pre-lighting all, a method of pre-lighting a predetermined time before the key pressing timing. Note that the first mode and the second mode may be reversed.

FIG. 2 is a diagram showing a format of performance data used in the electronic keyboard instrument. The performance data is input from an external device via the interface 14 or stored in the external storage device 13. The performance data is composed of a plurality of tracks, and the data of each track is composed of event data and timing data indicating the timing of reading the event data. The event data includes note-on data, note-off data, system exclusive messages, and the like. The note-on data is data for instructing start of sound generation, and includes a code indicating the note-on data, a MIDI channel number, a note number, and a velocity. The note-off data is data for instructing the end of sound generation, and includes a code indicating the note-off data, a MIDI channel number, a note number, and a velocity. The note number is numerical data representing the pitch, and is 0/127. In the case of a 61-key keyboard, the note number ranges from 36 (C1) to 96 (C
6) is the target of the key press guide. The velocity is a parameter for controlling a tone signal to be formed, and is mainly used for volume level control. In the case of a keyboard instrument, the velocity is generated corresponding to the key-depression speed, and this velocity is used for volume control and filter control (level control of harmonic components) in the tone generator circuit.

The system exclusive message is a data format used when information other than performance information is transmitted using the MIDI format. The system exclusive message is used to turn on / off the guide mode of the key press guide and to change the setting of the guide level. It is used when control is performed from an external device connected via the external memory 14 or when control is performed for each performance data read from the external storage device 13.

The format of the performance data is "event + relative time" in which the time of the performance event is represented by the time from the immediately preceding event, and the time in which the performance event is generated is represented by the absolute time in the music or bar. "Event + absolute time", "pitch (rest) + note length", which represents performance data in note pitch and note length or rest and rest length, memory area for each minimum resolution of performance Any form, such as a so-called "solid system", which secures the performance event in a memory area corresponding to the time when the performance event occurs, may be used. The automatic performance data may have a format in which a plurality of channel data are mixed, other than a format in which data of each channel is separated for each track.

FIG. 3 is a diagram in which performance data used in the electronic keyboard instrument is developed on a time axis. In this figure,
A bar shown by a dotted line indicates a note-on section having a velocity of 1, and a bar shown by a solid line indicates a note-on section having a velocity of 2 or more. The note-on section indicates the time from note-on data to note-off data. When automatic performance is being performed, note data is input to the tone generator 21. If the velocity is extremely small, such as 1 or 2, the tone signal formed does not reach the audible level. Therefore, note data having a velocity that is somewhat higher is a signal that is actually heard as a musical tone of the automatic performance. The threshold between audible and inaudible levels is
Since it differs depending on the listener, it cannot be unconditionally determined. However, if the velocity is less than 10, the non-audible level may be used. Therefore, in this electronic keyboard instrument, the data of velocity 1 is used as the data for notice lighting in the guide mode. That is, note data of velocity = 1 with the same note number (pitch) is written at a position before a predetermined timing before note data (velocity is 2 or more) for actually producing a musical tone, and According to the note-on data, the LED of the key corresponding to the note number is turned on in the first mode to notify that the key-on timing is coming soon. The lighting in the first mode is called advance lighting. Then, the LED is turned on in the second mode by note-on data for actually generating sound.
The lighting in the second mode is called timing lighting. The first mode and the second mode are constant lighting and short-time blinking as described above. By differentiating the lighting mode between the advance lighting and the timing lighting in this way, it is possible to distinguish and notify the key-on timing or the current key-on timing soon depending on the lighting mode.

The performance data shown in FIG. 3A is an example of performance data configured to indicate the next note when one note instruction is completed. That is, note data of velocity 1 for notice lighting of the next note data is embedded in a break of the note data for actually producing a musical tone (immediately after the note-off timing), and after the musical tone to be guided is completed. The LED of the musical tone to be guided next is turned on in advance. The performance data shown in FIG. 3B is an example of performance data in which a song is divided into phrases, and for each phrase, all LEDs of keys that are turned on in the phrase are turned on in advance. That is, note data having the same note number as all the note data actually generated in the phrase is written in the entire section from the start to the end of the phrase with velocity = 1. As a result, the LEDs of all the keys to be turned on in this phrase can be turned on at the beginning of the phrase, thereby making it possible to grasp the position where the hand is placed when the phrase is played. Note that, in this figure, the LED of the note number is lit in advance (lit in the second mode) even after the end of sounding (after the end of the note-on section for actually sounding). The warning light may not be turned on.

In the performance data shown in FIG. 3A, it is necessary to sound the actual sound of a certain note one by one in order to turn on the notice during the sounding of the next note. It is necessary to make the note-off not continuous. For this reason, when using performance data in which note-on-note-on and note-off-note-off are continuous, an apparatus for outputting event data (external apparatus)
And devices that receive event data (electronic keyboard instruments)
The performance data may be processed so that note-on → note-on or note-off → note-off does not continue.
For example, when two consecutive note-on data are received or read, a note-off corresponding to the first note-on is forcibly generated before the second note-on data. I just need. This process can be performed by storing the note on / off state for each note. Further, a note-on event having a velocity of 1 may have a velocity of 1 for a corresponding note-off event.

In addition, note data having a velocity of 1 may be embedded before a certain timing (for example, a quarter note) of note data that is actually sounded, and the temporal form of notice lighting can be set as appropriate.

FIG. 4 is a flowchart showing the MIDI receiving process. This process is a part of the automatic performance program, and is executed when MIDI data, which is performance data, is received from an external device via an interface. In addition, external storage devices for electronic keyboard instruments and RA
The same operation is performed when the performance data stored in the M and ROM is read out for automatic performance.

First, it is determined whether the received data is a system exclusive message (s1). If the message is a system exclusive message, processing according to the content of this message is executed (s2). The data for changing the setting of the guide mode, which gives advance notice and timing lighting during automatic performance, also consists of system exclusive messages. By inputting a system exclusive message including this guide mode setting change data from an external device, the external device Control such as ON / OFF of the guide mode.

If the message is not a system exclusive message, it is determined whether the message is note-on event data or note-off event data (s3, s4). If the data is note-on event data, sound generation processing is executed according to the content (s5). However, when the velocity data of the note-on event data is an extremely small value such as 1, no audible tone signal is formed, which is the same as that the tone-on event data is not actually generated. In this sound generation processing operation, it is also possible to reduce the load on the sound source by determining the velocity and not executing the sound generation processing for data having an extremely small value such as 1.

Thereafter, it is determined whether the guide mode is on (s6). If the guide mode is on, it is determined whether or not the velocity of the note-on data is 1 (s7). If velocity = 1, the keyboard LED 19a is turned on (notice light) in the first mode according to the LED control mode (s8). By the notice lighting, a key to be pressed soon can be designated in advance. On the other hand, if velocity ≧ 2, the keyboard LED is turned on (timing turned on) in the second mode according to the LED control mode (s9). By this timing lighting, the key pressing timing can be instructed. LED control mode is LE
This is a mode in which the lighting / flashing mode of D is set in various ways. For example, it determines which of the above-described constant lighting mode and blinking mode is used for the advance lighting. For example, LE
When the D control mode is 1, the notice lighting is set to the constant lighting method (first mode), and the timing lighting is set to the blinking method (second mode).
When the LED control mode is 2, the opposite is true. By selecting the LED control mode, the performer can make advance lighting and timing lighting in a lighting method that suits his / her preference. If the guide mode is off, the process returns directly from s6.

If the received MIDI data is a note-off message, the process executes a process for silencing the tone specified by the message (s12), and then determines whether the guide mode is on (s13). If the guide mode is on, the keyboard LED 19a corresponding to the note number of the note-off data is turned off (s14). In the case of data other than note-on data and note-off data, for example, program change data for tone color change, the corresponding other processing is executed and the process returns (s11).

When the performance data shown in FIG. 3 is received and the operation shown in FIG. 4 is executed, the keyboard LED corresponding to the pitch is lit in the second mode at the time of key depression, and the keyboard is illuminated a predetermined time before that. The LED lights up in advance in the first mode.

As described above, this electronic keyboard instrument can be automatically played by the operation of FIG. 4 by inputting performance data in real time from an external device. In this case, as shown in FIG. In addition, the external device and this device
It is connected by an IDI cable or the like, and receives performance data including a system exclusive message via the cable. Then, the external device transmits performance data to the electronic keyboard instrument by the operation shown in FIG.

In FIG. 4B, it is determined whether or not the external storage device is performing an automatic performance, that is, whether or not performance data is being reproduced (s20). If playback is in progress, playback / MIDI output processing is executed (s21). This playback
The MIDI output process is to read performance data stored in the external device in accordance with a predetermined tempo, and to read the event data when the event data is read.
This is a process of outputting DI data to an electronic keyboard instrument.

Thereafter, it is determined whether or not the guide mode has been changed (s22). The guide mode is changed by, for example, a guide mode switch provided on an external device. When the guide mode is changed, the guide mode itself is turned on / off according to the change.
A system exclusive message for instructing turning off or changing the LED control mode is formed and output to the electronic keyboard instrument (s23). Further, other processing is executed (s24). The other processing is, for example, processing such as start / stop of reproduction.

With the above operation, the performance data can be input from the external device to the electronic keyboard instrument which is an automatic performance device, and the system keyboard exclusive message of the present invention can be transmitted by transmitting the system exclusive message from the external device. Of the guide mode can be changed.

In the flowchart of FIG. 5, the guide mode is changed by operating the guide mode switch by the user. However, a system exclusive message for instructing the change of the guide mode is embedded in the performance data. The system exclusive message may be transmitted by reading the performance data.

In the above embodiment, velocity = 1
Is used as the data for the notice lighting, but not only the data of velocity = 1 but also data of a velocity that does not substantially generate an audible level musical tone should be used as the notice lighting data. Can be.
In this case, more complicated control is possible, such as changing the lighting mode according to the velocity value.

FIG. 6 is a flowchart showing an example in which velocities = 1, 2, and 3 are used for different controls. This operation is performed in place of s7 to s9 in FIG.

4 and 6, when note-on data is input (s3) and the guide mode is on (s6), the velocity of the input note-on data is one of 1, 2, and 3, or Is determined to be more than the above (s30, s31, s32). If the velocity is 1 (s30), the keyboard LED corresponding to the note number of the note-on data is turned on in the first mode (s34) in any case where the guide level is 1 to 3 (s33).
If velocity = 2 (s31), the guide level is 2
Or at 3 (s35), the keyboard LED corresponding to the note number is turned on in the first mode (s36). Also,
If velocity = 3 (s32), the guide level is 3
Only in the case of (s37), the keyboard LED corresponding to the note number is turned on in the first mode (s38). If the velocity is higher than this, the keyboard LED corresponding to the note number of the note-on data is turned on in the second mode because the note data is actually pronounced (s39).

In the above operation, in the case of a song with four beats,
For example, the data for the notice lighting of velocity 1 is written to the note of the first beat of each bar, the data for notice lighting of velocity 2 is written to the note of the third beat, and all the remaining notes are written. By writing the advance notice data of velocity 3 in advance, when the guide level is 1, only the key-on of one bar (the first beat) is announced by advance notice lighting in one bar, and the guide level of 2 At times, two keys (1st beat, 3rd beat) are turned on in advance,
When the guide level is 3, the key-on of all the notes is announced by the advance lighting. By doing so, one measure per measure
If you are a beginner who only needs to play along with the notes for automatic performance, set the guide level to 1 and execute the key press guide. If you want to play all notes together, set the guide level to 3, and The corresponding keyboard LED 19a may be turned on for the note of. Conversely, an intermediate person can play all notes with a guide of about one note per bar (that is, if there is a guide for only a part of the notes, the remaining notes can be played without guides). You may practice in step 1. The change of the guide level is also included in the above-described setting change of the guide mode, and can be changed from an external device by a system exclusive message.

In addition to the method of making the velocity values correspond to different guide levels as described above, the guide contents (instructing the next note / instructing all the notes in one phrase / indicating when the finger is opened) according to the velocity value Range, etc.) may be changed, a plurality of velocity values may be associated with the fingers, and fingering may be displayed according to the values. The guide and the left-hand guide may be switched. In this case, note data having different velocity values is embedded in the performance data in correspondence with the contents of each guide.

As the display means used for the guide,
Instead of using the keyboard LED, a picture of the keyboard may be displayed on an LCD or an external display, and the display form may be controlled based on a note event having a small velocity value. Further, even when the keyboard LED is used, the lighting in the first mode and the lighting in the second mode are not limited to the continuous lighting and the short-time blinking, and the light emission luminance may be changed by duty ratio control or the like. The first and second aspects may be distinguished from each other. Alternatively, when a two-color LED is used, the first and second aspects may be distinguished by changing the emission color. .

Also, in this embodiment, the performance data for the notice lighting includes the notice lighting of velocity = 1 (including the velocity = 2, 3 in FIG. 6) as shown by the broken line in FIG. Note event data (preceding note data) is written together with note event data (actual note data) for actually generating a sound whose velocity is greater than about 10, but such preceding note data is written in advance. In addition to the method of reading the performance data stored in the storage medium and reading out the data to perform the key press guide, the performance data of only the actual note data is read, and the preceding note data is automatically generated and added. Thereafter, a key press guide may be provided.

FIGS. 7 and 8 are flowcharts showing a first preceding note generation process for automatically generating preceding note data by reading performance data of only actual note data (note data having an audible level velocity value). It is. This process is a process for automatically generating a preceding note corresponding to the method of turning on the key until the key is pressed after the previous key is turned off as shown in FIG. 3A. This is a process executed as the process (s24).

In FIGS. 7 and 8, the performance data of the guide track stored in the performance data storage device in the external device is loaded into a work area of a RAM provided in the external device (s40). Then, the first performance data in the loaded performance data is read (s41). It is determined whether or not the first performance data is note-on data (s42), and subsequent performance data is read until it is determined to be note-on data (s43). If it is determined that the read performance data is note-on data, note-on data having a note number of the note-on data and a velocity value of “1” is generated, and It is inserted (s44). Thereafter, note-off data having the note number of the note-on data is generated and inserted immediately before the note-on data (s4).
5).

Then, the next performance data is read (s46).
It is determined whether or not the next performance data is note-on data (s47), and the subsequent performance data is read until it is determined to be note-on data (s51). If it is determined that the read performance data is note-on data,
It is determined whether there is any other note data that is simultaneously turned on (s48). If there is no other note data that is turned on at the same time, it has the note number of the note-on data and the value of the velocity is ""1" is generated. Then, the immediately preceding note-off data is searched, and the generated note-on data is inserted immediately after the found note-off data (s49). Thereafter, note-off data having the note number of the note-on data is generated and inserted immediately before the note-on data (s50). If there is another note data that is turned on at the same time, it means that the current key-depression timing has been reached before the previous key-off occurs, so that note data for guide is not inserted. The above processing from s47 to s51 is repeated until the end data in the performance data is read (s52). When the end data is read (s52), the performance data is saved, that is, replaced with the original performance data (s53). This processing ends.

FIGS. 9 and 10 are flowcharts showing a second preceding note generation process for reading performance data of only real note data and automatically generating preceding note data. This process is a process of automatically generating a preceding note corresponding to a method of pre-lighting all the LEDs of the keys depressed by the phrase for each phrase shown in FIG.
This is a process executed by the external device as another process (s24) prior to the automatic performance.

In FIGS. 9 and 10, the performance data of the guide track stored in the performance data storage device in the external device is loaded into the work area of the RAM provided in the external device (s60). Then, the loaded performance data is divided into a plurality of phrases (s61). As a division method, a method of analyzing performance data and automatically dividing the data into a plurality of phrases (for example, Japanese Patent Laid-Open No. 8-29276).
No. 2) or a method in which a user specifies a division position by using a switch device or the like to divide the phrase into a plurality of phrases, and any one of the methods may be appropriately employed. Thereafter, all the note-on data included in the leading phrase of the plurality of divided phrases are searched, and each note-on data of all the found note-on data is found, and the velocity value is “1”. A plurality of note-on data is generated and inserted at the beginning of the phrase (s62).

Next, the performance data next to the note-on data insertion position is read (s63), and it is determined whether or not the next performance data is note-on data (s64). Note-off data having the note number of the note-on data is generated and inserted immediately before the note-on and data (s65). On the other hand, if the next performance data is not no-on data, it is determined whether or not it is note-off data (s66). If the next performance data is note-off data, it has the note number of the note-off data,
In addition, note-on data having a velocity value of “1” is generated and inserted immediately after the note-off data (s6).
7). After these, or if the data is not note-on data or note-off data, the next performance data is read (s68). The above processing from s64 to s68 is repeated until the end of the phrase is reached. When the end of the phrase is reached (s69), a plurality of note-off data having each note number of all note-on data found in the phrase is generated. And insert it at the end of the phrase (s7
0). If the performance data read out in s68 is not end data, search for all note-on data included in the phrase for the next phrase,
A plurality of note-on data having each note number of all found note-on data and having a velocity value of “1” is generated and inserted at the beginning of the phrase (s7
2). Then, the performance data next to the note-on data insertion position is read (s73), and the processing from s64 is repeated.
When it is determined that the performance data read out in s68 is end data (s71), the performance data is saved (s74), and this processing ends.

FIG. 11 shows a third example in which performance data of only actual note data is read and preceding note data is automatically generated.

In FIG. 11, performance data of a guide track stored in a performance data storage device in an external device is loaded into a work area of a RAM provided in the external device (s80). Then, the first performance data in the loaded performance data is read (s81). It is determined whether or not the performance data is note-on data (s82).
The subsequent performance data is read until it is determined that the data is note-on data (s85). If the subsequent performance data is determined to be note-on data, the note data has the note number of the note-on data and the velocity value is “1”.
Is generated and inserted before a predetermined timing (for example, a quarter note) of the note-on data (s83). The predetermined timing may be appropriately changed by the user. Thereafter, note-off data having the note number of the note-on data is generated and inserted immediately before the note-on data (s84). S82 above
To s85 are repeated until the end data in the performance data is read out. At the time when the end data is read out (s86), the performance data is saved (s87), and this processing ends.

In the processing of FIG. 11 from the part 7, the performance data including only the actual note data is replaced with the performance data including the preceding note data. Performance data including note data may be newly stored separately.

According to the first, fifth and sixth aspects of the present invention, when the volume instruction data is equal to or less than a predetermined value, a performance operation is instructed in the first mode, and the volume instruction data exceeds the predetermined value. When the performance operation is instructed in the second mode, the player can know the level of the volume command data according to the mode of the instruction, and the performance method can be changed in advance. Has the advantage of being easier.

According to the second aspect of the present invention, furthermore, the predetermined value or less is divided into a plurality of sections, and the mode of the instruction is changed depending on which section the volume instruction data belongs to. A performance instruction can be given in accordance with the skill of the player, and a performance guide can be provided to the player more kindly.

According to the third aspect of the present invention, the predetermined value is a small volume instruction data value that does not form a signal of an audible volume level. It can be used exclusively for a performance guide instead of a performance, and it is possible to perform a complicated and kind performance guide such as a warning light in a normal automatic performance operation. Further, even when the performance data is reproduced by a device having no guide function, since the format of the performance data is the same as that of the conventional one, it operates without any problem.
