2. Description of the Related Art Conventionally, automatic performance data is prepared in advance, and each time a player operates an operator such as an arbitrary keyboard or pad, the automatic performance data is read out and played. A device has been proposed. In such an automatic performance device, each time the operating element is operated once, one operation is performed.
One note data (a plurality of note data in the case of a chord) is read and sounded. Therefore, an automatic performance can be performed by sequentially depressing an arbitrary key or the like at a rhythm and a tempo corresponding to the music of the automatic performance data.

In this type of automatic performance device, a display is provided on an operation panel of an electronic musical instrument provided with the automatic performance device, and a navigation for displaying a timing such as a key press based on the automatic performance data is performed. Some had features. The example of the note navigation display used conventionally is
As shown in FIG.

In FIG. 7, reference numeral 101 denotes a liquid crystal display unit provided on an operation panel or the like of an electronic musical instrument, on which a navigation display indicating the timing of key depression or the like is performed. The liquid crystal display unit 101 is capable of displaying up to 16 ASCII codes or a predetermined number of registered characters in the horizontal direction, and is used to display automatic performance data having a length of four quarter notes. The key timing is configured to be displayed on only one line.

That is, by displaying a black circle (●) in an arbitrary area of the display area for 16 characters, the key depression timing of the performance data is indicated by the position of the black circle from left to right of the liquid crystal display unit 101. It had been. Also, when an automatic performance for one line is performed in accordance with the navigation display for one line, the display is switched to the next one line.

[0006]

However, in the above-described conventional navigation display, a key depression timing of a length of four quarter notes is displayed for only one line, so that the player can immediately follow the key. I could only know the key press timing. In addition, immediately after executing the last performance displayed in the one line, the display is switched to the next one line of the navigation display. In particular, in the display switching part, the next key pressing timing is known until immediately before the switching. Can not
There was a problem that it was difficult to play.

In the conventional navigation display, the time interval between key presses is long where the interval between black circles is large.
Conversely, it is possible to intuitively know that the time interval between key presses is short where the interval between black circles is small. But,
With the display of only the black dots, the beat of the performance data is not clearly understood, and it is also difficult to know to what beat the position of the displayed black dot belongs. Was.

Further, in order to practice playing an electronic musical instrument, the above navigation function may be used. In such a case, in the conventional navigation display, the right hand and the left hand are not distinguished from each other, so that the playing timing is practiced, but there is a problem that how to use the left and right is difficult to understand.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and it is possible to improve the visibility of a navigation display of a key-depression timing, and to practice key-depression for playing an electronic musical instrument.

[0012]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a block diagram showing a schematic configuration of an electronic musical instrument to which the automatic performance device of the present embodiment is applied. In FIG. 1, a CPU 10, a ROM 11,
The RAM 12, the keyboard scan circuit 15, and the tone generator 17
Bus lines 20 such as a data bus and an address bus, respectively.
, So that data transmission and reception are performed mutually.

The keyboard scanning circuit 15 includes a keyboard 16
Is connected. The keyboard 16 includes one or a plurality of keys including a plurality of keys and a key switch provided corresponding to each of the keys. The keyboard scan circuit 15
In addition to detecting key depression and key release of the keyboard 16 in accordance with the state of the key switch, it is also configured to detect the key operation speed. In the automatic performance mode, any key on the keyboard 16 is used to instruct reading of automatic performance data, and the performance data is sequentially read out by a predetermined amount each time the player presses any key. Automatic performance is performed.

The CPU 10 has an operation panel unit 13.
And an external I / F 14 are connected. Operation panel unit 1
Reference numeral 3 denotes, in addition to various controls for setting a tone color, a volume, an effect, a rhythm, and the like, controls used for performing an automatic performance based on the automatic performance data (selection of performance data, setting of a tempo, etc.). For displaying the various setting states by the above-mentioned various operators, and a navigation device for navigating the key press timing. Also,
The external I / F 14 is configured by a MIDI interface or the like.

The CPU 10 controls the entire electronic musical instrument in accordance with the control program stored in the ROM 11 while using the RAM 12 as a work memory. For example, in the manual performance mode, a scan process of each key switch on the keyboard 16 and a scan process of each operator on the operation panel unit 13 are performed, and the operation state of each key on the keyboard 16 (key pressed, key released, operated, etc.). By detecting the key switch number (key number) of the key, the velocity related to the key operation speed, and the operation state of each operator on the operation panel unit 13, and supplying it to the sound source unit 17, each key or each operation is detected. The sound processing and the like according to the operation of the child are executed.

In the automatic performance mode, the CPU 10 stores the automatic performance data selected by a switch provided on the operation panel section 13 every time a key is pressed.
A predetermined amount is sequentially read from the OM 11 and is read out from the sound source unit 1.
7 to generate and output a corresponding tone signal. At the same time, a process of displaying the key press timing navigation on a display on the operation panel unit 13 based on the read automatic performance data is also performed.

The ROM 11 stores, in addition to a program storing various processing procedures of the CPU 10, automatic performance data used when performing an automatic performance as several types of preset data. Also, it stores tone waveform data such as PCM used when the tone generator 17 forms tone data. Further, the RAM 12 has a storage area for temporarily storing various necessary data in the course of the execution of the program by the CPU 10 and for storing data obtained as a result of various processes. User data generated by freely editing preset automatic performance data in the ROM 11 is also stored in the RAM 12.

The tone generator 17 has a plurality of tone generation channels, and is configured to generate a plurality of tone simultaneously. The tone generator 17 reads out PCM tone waveform data from the ROM 11 based on key number information (note information) representing each key sent from the CPU 10 and tone parameter information set by operating each operation element. After processing the amplitude and the envelope, the set effect is applied to form digital tone data.

The digital tone data formed by the tone generator 17 is converted into an analog tone signal by a D / A converter (not shown) in the tone generator 17. The tone signal is amplified by the amplifier 18 and then supplied to the speaker 19 for sound emission.

FIG. 2 is a diagram showing an example of a navigation display on a display provided in the operation panel section 13. As shown in FIG. In the present embodiment, as the display 21 shown in FIG. 2, a bitmap liquid crystal display capable of drawing arbitrary characters, symbols, images, and the like in dot units is used, and the size of the display itself is also small. It is larger than the conventional display shown in FIG.

In the present embodiment, the liquid crystal display 21 displays four rows of key depression timings relating to automatic performance data having a length of four quarter notes. In each row, the first beat, the second beat,... At equal intervals from left to right of the liquid crystal display 21.
The key depression timings are black circle (●) 22a and white circle (○) 2
This is shown at position 2b. The navigation display of the black circle (●) 22a indicates the melody part (right hand), and the white circle
(○) 22b indicates an accompaniment part (left hand).

Further, in the present embodiment, in addition to the navigation display of the black circle 22a and the white circle 22b indicating the key depression timing, a bar line 23 indicating a bar break and a beat line 24 indicating a beat break are also combined. it's shown.

In the example of FIG. 2, the navigation display based on the automatic performance data of the time signature of a quarter is shown, so that three beat lines 24 are included in one line. 1
The number of beat lines 24 in a row varies according to the time signature of the selected automatic performance data. For example, in the case of the automatic performance data of a time signature of two minutes, there is one line in the center, in the case of the automatic performance data of the time signature of eight minutes, seven lines, and in the case of the automatic performance data of the sixteenth time, 15 lines. The beat line 24 is displayed in one line.

FIG. 2A shows an initial state displayed when certain automatic performance data is selected and automatic performance is to be started. In the initial state, the key pressing timings are all indicated by black circles 22a and white circles 22b. After that, when the automatic performance is started by pressing the key, as shown in FIG.
The display of a and the white circle 22b is switched to the cross mark (+) 25. FIG. 2B shows a state where the performance has been completed up to the third line from the top. In addition, each black circle 22a
, The lyrics of "Akatonbo" are displayed.

Next, as shown in FIG. 2C, when the key is actually pressed in accordance with the navigation display of the key pressing timing displayed at the beginning of the fourth line, the performance has already been performed and the The navigation display on the first line displayed as a new navigation display 26 according to the next performance data following the automatic performance data on the fourth line (also in this case, the key depression timing is the black circle 22a and the white circle) 22b, and the lyrics are displayed above the black circle 22a.). When the automatic performance data is completed on the fourth line, such switching is not performed.

Further, as shown in FIG. 2D, the performance of the fourth line is completed, and the first press of the first line is performed according to the new navigation display of the first line switched as described above. When the key is actually pressed at the key timing, the navigation display of the second to fourth lines, which has already been performed at that time and displayed by the cross 25, is changed according to the next performance data following the performance data of the first line. Is switched to the new navigation display 27 (also in this case, displayed by the black circle 22a and the white circle 22b at the key pressing timing).

When the automatic performance data is completed in the newly switched first line (the fifth line in total), such switching is not performed. In such a case, the second to fourth lines may be switched to blank. If the remaining automatic performance data is less than three lines of the second to fourth lines, the black circle 22a and the white circle 22
A new navigation display may be performed at b, and blank display may be performed thereafter. The example of FIG. 2D shows that the automatic performance data is completed in the second line of the newly switched display.

Here, the navigation display of the first line is switched when the key is pressed according to the first key pressing timing of the fourth line. However, the key pressing timing of the second and subsequent keys of the fourth line (however, , Except for the last key press timing). Also, 4
The navigation display of the first line may be switched when the key is pressed at an arbitrary timing on the second line or the third line before the line.

In the above example, the navigation display of the second to fourth lines is switched when a key is pressed according to the first key pressing timing of the first line. The switching may be performed when a key is pressed at a key timing (excluding the last key pressing timing).

The point is that, instead of switching to the next navigation display immediately before and immediately after the performance of a certain line is completed, switching to the next navigation display after the performance has already been performed when a certain amount of performance remains. , Any form is acceptable.

However, in the present embodiment, the unplayed timing and the played timing are indicated by the black circle 22a and the white circle 2 respectively.
Since the 2b and the cross 25 are distinguished from each other, if the display is switched too early, the display period of the cross 25 is shortened, and it may be difficult to understand how far the performance has been performed. Therefore, the example shown in FIG. 2 is more preferable.

In the example of FIG. 2, the navigation display of the first line is switched when the key is pressed according to the first key-depression timing of the fourth line. It is possible that In this case, since the navigation display on the fourth line is blank, it is not possible to determine whether the fourth line is a full rest or whether the automatic performance data is completed on the third line. So, in this case,
When the key is pressed at the first timing of the third line, the navigation display of the first line may be switched.

In the present embodiment, as described above,
Since the navigation display of the melody part played with the right hand and the navigation display of the accompaniment part played with the left hand are displayed separately, the user can know the key press timing by looking at the display surface of the display 21. Not only can you do it, but you can clearly see which key you should press with your left or right hand. Therefore, according to the electronic musical instrument of the present embodiment, it is possible to provide a display that makes it easy to practice the navigation display function when the user presses the keys of the electronic musical instrument.

The navigation display as described above is shown in FIG.
This is performed based on the automatic performance data read from the OM 11 or the RAM 12. As described above, the automatic performance data in the ROM 11 is the preset data, and the automatic performance data in the RAM 12 is the user data. As shown in FIG. 3, the sequence of the bar mark, beat mark, note data and end mark is used. It consists of.

Here, the bar mark is information indicating the delimitation of a bar, and also includes time signature information indicating how many minutes the automatic performance data is. This time signature information is 1
It may change in the middle of one automatic performance data. The beat mark is information indicating a beat break.

The note data includes a key number for specifying a pitch constituting a performance sound, a velocity for indicating a sound volume, a step time for indicating a sound timing from a bar mark or a beat mark, and a gate for indicating a sound time. It consists of time. The end mark is information indicating the end of the automatic performance data. Depending on the performance data, in addition to these, repeat end information including a repeat mark indicating a repeat point is included.

The CPU 10 shown in FIG. 1 first reads a bar mark, and reads the bar mark 2 according to the time signature information contained therein.
3 and the beat line 24 are displayed. Next, the note data is read, and the bar line 23 is read based on the step time therein.
Alternatively, a black circle 22a and a white circle 22b are displayed at a position corresponding to the step time from the position of the beat line 24. As described above, the lyrics are displayed in correspondence with the black circles 22a. In an initial state, such a work is performed for four lines, thereby realizing a navigation display as shown in FIG.

Thereafter, when the performance is actually started, the CP
Each time U10 is pressed, the U10 performs a process of switching the display of the black circle 22a and the white circle 22b indicating the key pressing timing at that time to the cross 25. Further, it is determined whether the key is pressed at the beginning of the third line, at the beginning of the fourth line, at the beginning of the first line, and if the result of the determination corresponds to any of these, as described above. To switch the navigation display.

FIGS. 4 to 6 are flowcharts for explaining in detail the operation of the electronic musical instrument according to the above-described embodiment. In the present embodiment, the automatic performance by key depression and the navigation display are both performed based on the automatic performance data in the ROM 11 or the RAM 12. However, the read pointer on the automatic performance data includes a performance pointer and a display pointer. Is managed in two ways.

FIG. 4 is a flow chart showing the operation when sound generation processing is performed based on the automatic performance data in accordance with the performance pointer. When the keyboard scanning circuit 15 detects that any key has been pressed, It is what is performed.
In FIG. 4, when any key is pressed, step S
In step 1, one piece of data indicated by the current performance pointer is read from the automatic performance data stored in the ROM 11 or the RAM 12.

Then, in step S2, it is determined whether or not the read data is a bar mark or a beat mark. If so, the process proceeds to step S3 because this is not the note data itself, and the performance pointer is set to the next. And returns to step S1. On the other hand, if the read data is neither a bar mark nor a beat mark, the data is note data, and the process proceeds to step S4.

In step S4, tone generation processing is performed according to the note data indicated by the current performance pointer. In the next step S5, the display of the black circle 22a (or white circle 22b) indicating the key pressing timing is switched to the cross 25 in accordance with the note data indicated by the current performance pointer. That is, based on the step time in the note data, the position of the black circle 22a (white circle 22b) at the timing of the currently depressed key is known from the immediately preceding bar mark or beat mark, and this is switched to the display of the cross 25.
As a result, the lyrics displayed on the black circle 22a also disappear.

Then, in step S6, the process of determining the switching of the navigation display is performed, and then in step S7, the performance pointer is advanced to the next, and the key pressing process ends. The specific contents of the navigation display switching determination processing in step S6 will be described later with reference to FIG.

FIG. 5 is a flow chart showing the operation when the navigation display processing based on the automatic performance data is performed according to the display pointer, and is executed when the navigation display for one measure (one line) is performed. Things. As described above with reference to FIG. 2, in the navigation display, four lines are displayed in an initial state before the performance starts, and after the performance starts, the first line or the second to fourth lines are collectively switched and displayed. You.

Therefore, in the initial state, the display pointer is ahead of the performance pointer by four lines, and
After the execution of the flowchart of (1), the pointer always indicates the head position of the line (it always corresponds to the bar mark).

In FIG. 5, first, in step S11, a bar mark indicated by the current display pointer is read from the automatic performance data. Bar line 23
And the beat line 24 are displayed. Then, in step S13, the display pointer is advanced to the next, and in step S14, data indicated by the current display pointer is read.

In step S15, it is determined whether or not the read data is a bar mark. If the read data is not a bar mark, the flow advances to step S16 to determine whether or not the read data is a beat mark.

If it is a beat mark, the process proceeds to step S17, where a black circle 22a and a white circle 22b indicating the key depression timing are displayed.
Is advanced to the position of the next beat line 24. That is, the black circle 22a and the white circle 22
This is because the display position b is a position advanced by a distance corresponding to the step time from the position of the immediately preceding bar line 23 or beat line 24, and therefore, it is necessary to sequentially advance the reference position every time a beat mark is read. Black circle 22a or white circle 2
When the note data related to the navigation display is a melody part, the note data is displayed as a black circle 22a.
If it is an accompaniment part, it is displayed as a white circle 22b.

On the other hand, if it is determined in step S16 that the read data is not a beat mark, the data is note data. In this case, the process proceeds to step S18, and it is determined whether or not the note data is a melody part.

If the result of this determination is that the note data is a melody part, the flow advances to step S19, and the distance from the position of the immediately preceding measure line 23 or beat line 24 to the step time included in the note data is determined. A black circle 22a indicating the key depression timing is displayed at the advanced position. At this time, the lyrics are also displayed on the black circle 22a.

On the other hand, if the result of determination in step S18 is that the note data is not a melody part, it is an accompaniment part, so the flow proceeds to step S20, and the key depression timing is set to a position advanced by a distance corresponding to the step time. The white circle 22b shown is displayed.

After the processes in steps S17 to S20, the display pointer is advanced to the next in step S200, and the process returns to step S14 to read the data indicated by the new display pointer. Then, in a step S15, it is determined whether or not the read data is a bar mark. Here, if the bar mark is displayed, it means that the navigation display for one bar has been completed, and thus the navigation display process ends.

FIG. 6 is a flowchart showing the operation of the navigation display switching determination process in step S6 shown in FIG. Note that the flowchart shown in FIG. 6 is executed every time a key is pressed after the automatic performance by the key pressing is started. On the other hand, in the initial state before the start of performance, when predetermined automatic performance data is selected, the flowchart shown in FIG. 5 is repeated four times based on the performance data, so that the navigation display has already been performed for four lines. It is assumed that

In FIG. 6, first, in step S21, it is determined whether or not the current performance pointer corresponds to the first navigation display position on the third line from the top of the liquid crystal display 21, and if so, the process proceeds to step S21. Proceeding to S22, it is determined whether or not the automatic performance data on the fourth line is all rests. If the fourth line is not a full rest, the present process is terminated because it is not the switching timing of the navigation display, but if the fourth line is a full rest, the process proceeds to step S24.

On the other hand, if it is determined in step S21 that the current performance pointer is not at the first position on the third line, the process proceeds to step S23, where the current performance pointer becomes 4
Determines if it is the first position on the line. Here, when the first position in the fourth row is hit, the process proceeds to step S2.
Proceed to 4. In step S24, it is determined whether or not the next performance data (performance data following the performance data on the fourth line) still exists. If so, the process proceeds to step S25, and the navigation on the first line is performed based on the performance data. Switch the gate display. That is, here, the process of the flowchart shown in FIG. 5 is performed once. Then, the process proceeds to step S26.

If it is determined in step S23 that the current performance pointer does not hit the first position on the fourth line, the process jumps to step S26, and it is further determined whether or not the current performance pointer hits the first position on the first line. I do.

If it is the first position on the first line, the flow advances to step S27 to determine whether or not the next performance data still exists. If there is, the process proceeds to step S28, and the navigation display of the second to fourth lines is switched based on the performance data. That is, here, the processing of the flowchart shown in FIG. 5 is performed three times.

On the other hand, if it is determined in step S26 that the current performance pointer does not reach the first position on the first line, the present processing is terminated because it is not the timing for switching the navigation display.

If it is determined in step S24 or step S27 that the next performance data does not exist, it is time to switch the navigation display. Since the process has reached the stage, this process is also terminated in this case.

As described above, in the present embodiment, a liquid crystal display 21 which is capable of displaying a bit map and which is larger than the conventional one is provided as a display provided on the operation panel section 13 and has a length of four quarter notes. The navigation display of the key depression timing is displayed for four lines. As a result, the performance can be performed while grasping not only the key depression timing immediately after the current performance but also a key depression timing that is considerably earlier, and the performance can be facilitated.

In this embodiment, not only the black circle 22a and the white circle 22b representing the key depression timing but also the bar line 2
3 and the beat line 24 are also displayed. Thereby, the time signature of the currently selected automatic performance data can be clearly understood, and it can be easily understood to which beat the positions of the displayed black circles 22a and white circles 22b belong, and the key press timing can be further improved. It can be easier to grasp.

Further, in this embodiment, when a performance is performed in accordance with the navigation display of a certain row, the navigation display of the already played row is switched to a new navigation display in advance. For example, in the example of FIG. 2, the first line is newly displayed when the performance enters the last line currently being navigated, and the second and subsequent lines are displayed when the performance enters the first line from the last line. Is newly displayed.

As a result, the navigation display ahead of time is always performed with a margin in advance, so that the key-depression timing can be more easily grasped, and the performance can be further facilitated.

In the above embodiment, the navigation display for four quarter notes is displayed for four lines. However, the present invention is not limited to four lines, and any number of lines may be used as long as a plurality of lines are displayed. Absent. Further, the amount displayed in one line is not limited to four quarter notes, and a longer or shorter amount may be displayed. Further, as described above, the timing of switching the navigation display is not limited to the key press timing at the top of the first row, the top of the third row, and the top of the fourth row.

The marks indicating the key depression timings of the unplayed and played keys are not limited to the black circles 22a, the white circles 22b, and the crosses 25 described above. Furthermore, in the above-described embodiment, an example in which the automatic performance device of the present invention is applied to an electronic musical instrument having the keyboard 16, for example, an electronic piano, an electronic organ, or a keyboard musical instrument such as a synthesizer, has been described.
