FIG. 3 shows a storage data format of the music data storage section of the RAM 24. A plurality of pieces of music data for musical score display are transferred to a music data storage unit of the RAM 24 from a recording device such as a floppy disk (not shown) (or from another machine via the interface 26) before the performance.

The music data for musical score display is composed of display control data and musical score data for each music. In FIG. 3, S ₁ , S ₂ , and S ₃ are display control data, and V ₁ is score data corresponding to S ₁ . Note that S ₂
, S ₃ are not shown.

In order to explain the structure of music data for one music,
Data S ₁ and V ₁ will be taken up as a representative. In the display control data S ₁ , address data AD and note length data LD are arranged for each display section after the header information HD, and end data ED is arranged at the end. Also, the score data V
_{In No. 1} , musical score image data VD is arranged for each one display section.

The address pointer SAPNT is used to read the display control data of the selected music piece. The address pointer VAPNT, to which the address data AD is set, is used to read the score image data of the selected music piece.

FIG. 4 shows the flow of processing of the main routine, and this routine starts when the power is turned on.

First, in step 40, initialization processing is executed to initialize various registers. For example,
The flags RUN and ENDF are both set to 0.

Next, at step 42, a keyboard processing subroutine is executed as will be described later with reference to FIG. Then, the process proceeds to step 44, and a switch (SW) process subroutine is executed as described later with reference to FIG.

Thereafter, in step 46, a display update process subroutine is executed as described later with reference to FIG. Then, in step 48, other processes are executed, and then the process returns to step 42, and the subsequent processes are repeated in the same manner as described above.

FIG. 5 shows a keyboard processing subroutine. In step 50, the keyboard scanning circuit 12 is used to perform the key scanning processing. Then, the process proceeds to step 52, and it is determined whether or not there is a key event (key-on event or key-off event) on the keyboard 12A. If this determination result is affirmative (Y), the process proceeds to step 54.

In step 54, it is determined whether the key event is the key-on event. If the result of this determination is affirmative (Y), sound generation processing is performed in step 56. That is, the tone pitch data corresponding to the pressed key and the key-on signal are supplied to the vacant tone generation channels in the tone generator circuit 28 to generate tone signals corresponding to the tone data. As a result, the sound system 30 produces a musical sound corresponding to the pressed key.

If the result of the determination at step 54 is negative (N), then the mute processing is carried out at step 58. That is, the key-off signal is supplied to the tone generation channel that is generating the tone signal corresponding to the released key, and attenuation of the tone signal is started.

When the processing of step 56 or 58 ends, or when the determination result of step 52 is negative (N), the routine returns to the routine of FIG.

According to the keyboard processing of FIG. 5, it is possible to generate a manual performance sound in response to a performance operation on the keyboard 12A. That is, the player can perform a manual performance while watching the score display on the display DPL.

FIG. 6 shows a SW processing subroutine. In step 60, a switch (SW) scan processing is performed using the SW scanning circuit 14. Then, the process proceeds to step 62, and it is determined whether there is a switch (SW) event.

If the determination result of step 62 is affirmative (Y), the process proceeds to step 64, and the process corresponding to the switch (SW) with event is executed as described later with reference to FIGS.

When the processing of step 64 is completed or when the determination result of step 62 is negative (N), the routine returns to the routine of FIG.

FIG. 7 shows a subroutine of the music selection SW process. In step 70, the header information HD of the music selected by the music selection SW is read out, and processing such as register setting and display is performed. That is, of the header information HD
Time signature data is stored in the time signature register, measure number data is stored in the bar number register, switching position data is stored in the switching position register CP,
The tempo data is set in each tempo register.
Then, based on the time signature data of the time signature register and the measure number data of the measure number register, for example, as shown in FIG. 2, a 5-bar staff of four measures and a time signature "3/4" are displayed on the display device DPL.

The display device DPL displays the tempo value TM based on the tempo data in the tempo register. Also,
The interrupt period (tempo clock period) of the timer 22 is set based on the tempo data of the tempo register.

On the other hand, the display section length register ZL is set in FIG.
As shown in 3, data indicating the display section length ZL by the tempo clock number is set. In this embodiment, since the length of the quarter note is represented by the tempo clock number 24, the display section length ZL is represented by 24 × beat number × display measure number. For example, assuming that the number of beats is 3 (3/4 beats) and the number of displayed measures is 4, data indicating the tempo clock number 288 is set in the register ZL.

When the switching position data is set in the switching position register CP, one of the display element LEDs corresponding to the SWs 14a to 14c shown in FIG. 2 is turned on. As shown in FIG. 13, the switching position data represents the switching position before the end of the display section by the length CP by the number of tempo clocks. For example, in the case of 3/4 beat, if the length CP is 1 bar, 1/2 bar, and 1/4 bar, the switching positions corresponding to these are 72 and 3, respectively.
It is represented by 6, 18 tempo clocks. The length from the start of the display section where the value of the tempo counter TCNT is 0 to the switching position is ZL-, where ZL is the display section length and CP is the length from the end of the display section to the switching position.
It is represented by CP, for example, ZL = 288, CP = 36 (1
/ 2 bar), 288-36 = 252.

Next, at step 72, the pointer SAP
The address data AD is read by advancing NT, and the pointer V
Set to APNT. Then, the process proceeds to step 74.

At step 74, the musical score image data VD indicated by the pointer VAPNT is read and displayed on the display DPL. As a result, the score of the first four measures in the selected song is displayed on the display DPL as shown in FIG.

Next, at step 76, the pointer SAP
Advance NT to read note length data LD, register LA
Set to ST. Then, the process proceeds to step 78.

At step 78, the pointer SAPNT is advanced to read the address data AD of the next display section. Then, in step 80, the read address data AD
Is set in the pointer VAPNT. This is a preparation process for reading out the score image data of the next display section.
After this, the process proceeds to step 82.

At step 82, the tempo counter TCN
Set T to 0. Then, the process proceeds to step 84, T
The location pointer LP is displayed on the display DPL based on the value of CNT. As a result, the pointer LP is displayed at the start position of the display section. After step 84,
It returns to the routine of FIG.

FIG. 8 shows a start / stop SW processing subroutine. Usually, after selecting a desired song with the song selection switch, the start / stop switch is turned on so that the song can proceed with respect to the displayed score.

In step 90, the value of the flag RUN is 1
Determine whether. First start after step 40 in Figure 4 /
The value of RUN is 0 when the stop SW is turned on.
In this case, the determination result of step 90 is negative (N), and RUN is set to 1 in step 92. As a result, it becomes possible to advance the music. After step 92, the routine returns to the routine of FIG.

On the other hand, when the selected song is finished playing,
When the start / stop SW is turned on in the state of = 1, the determination result of step 90 becomes affirmative (Y), and the process proceeds to step 94.

At step 94, the flags RUN and END are set.
Set 0 to F. Then, in step 96, the score display is returned to the beginning. That is, the score of the first four measures is displayed on the display DPL in the same manner as described in step 74 of FIG. After step 96, the routine returns to the routine of FIG.

FIG. 9 shows a timer interrupt routine, which is started each time the tempo clock signal is generated from the timer 22.

First, in step 100, the flag RUN is set.
Is 1 is determined. If the determination result is negative (N), the process returns to the routine of FIG.

If the process goes to step 100 for the first time after setting RUN to 1 in step 92 of FIG. 8, step 1
The determination result of 00 becomes affirmative (Y), and step 101
Move on to. In step 101, it is determined whether the flag ENDF is 1. Since ENDF is not 1 before setting 1 in step 124, the determination result in step 101 is negative (N), and the process proceeds to step 102.

At step 102, the tempo counter TC
Increase the value of NT by 1. Then, the routine proceeds to step 104, where it is determined whether the value of TCNT is equal to the value of the display section length register ZL minus the value of the switching register CP (whether the music progression has reached the switching position). If the determination result is negative (N), the process proceeds to step 106.

In step 106, it is determined whether the value of TCNT is equal to the value of the display section length register ZL (whether it is the end of the four measures being displayed). If the determination result is negative (N), the process proceeds to step 108.

In step 108, the location pointer LP is displayed based on the value of TCNT. Step 1
Since the value of TCNT is advanced by 1 in 02, the pointer LP
Is displayed at a position shifted to the right by one step in response to an increase in the TCNT value by one. After step 108,
It returns to the routine of FIG.

The pointer LP has steps 100 to 108.
By repeating the above process, the player moves to the right as the music progresses. When the music progression reaches the switching position, the determination result of step 104 becomes affirmative (Y), and step 1
Go to 10.

In step 110, it is determined whether ENDF is 0. ENDF is 0 before the end data ED is read. In this case, the determination result of step 110 is affirmative (Y), and the process proceeds to step 112.

At step 112, the flag CHGF is set to 1
Set. This is to enable the display update process of FIG. Then, the process proceeds to step 114, and the display mode of the pointer LP is changed from the black filled state to the gray filled state.

Thereafter, at step 108, the pointer LP is displayed based on the value of TCNT, and then the process returns to the routine of FIG. It should be noted that the process returns to the routine of FIG. 4 also when the determination result of step 110 is negative (N).

When the routine returns to the routine of FIG. 4 through steps 110 to 114 and 118, the display updating process of step 46 causes the display DPL to display the following four-measure score instead of the score being displayed. The display update process will be described later with reference to FIG.

In the state where the score display is updated, FIG.
In the interrupt routine of, the processing of steps 100 to 108 is repeated. Therefore, the pointer LP moves to the end of the display section as the music progresses while the display mode is changed.

When the music progress reaches the end of the display section,
The determination result of step 106 is affirmative (Y), and the process proceeds to step 116. In step 116, ENDF is 2
Determine whether. Since ENDF is 0 before reading the end data ED, the determination result of step 116 is negative (N), and the routine proceeds to step 118.

In step 118, it is determined whether ENDF is 1. Since ENDF is not 1 before setting 1 in step 124, the determination result in step 118 is negative (N), and the process proceeds to step 120.

At step 120, TCNT is set to 0. As a result, for example, in the case of 3/4 time signature, TC
The value of NT changes from 288 to 0. Then, the process proceeds to step 122, and the display mode of the pointer LP is returned to the black solid state.

Next, at step 108, the pointer LP is displayed based on the value of TCNT. As a result, the pointer LP is displayed at the start position of a new display section in a black solid state. Thereafter, the process returns to the routine of FIG.

As the music progresses and the musical score display progresses as described above, the RAM 24 eventually displays the data shown in FIG.
The end data ED is read by the processing of 2, and 2 is set in ENDF in step 164. And
At the end of the last display section, in the interrupt routine of FIG. 9, the determination result of step 106 becomes affirmative (Y), and the routine proceeds to step 116.

At step 116, the determination result becomes affirmative (Y) due to ENDF = 2, and the routine proceeds to step 124. At step 124, ENDF is set to 1.
Then, in step 108, the pointer LP is displayed based on the value of TCNT, and then the process returns to the routine of FIG.

In the next timer interrupt, ENDF = 1
As a result, the determination result of step 101 becomes affirmative (Y), and the process goes to step 106 without passing through step 102. T
Since the value of CNT does not change, the determination result of step 106 becomes affirmative (Y), and the routine proceeds to step 116.

At step 116, the determination result is negative (N) due to ENDF = 1, and the routine proceeds to step 118. In step 118, it is determined whether ENDF is 1. The result of this determination is affirmative (Y), and the routine moves to step 126.

At step 126, RUN and ENDF are set.
0 is set in each of the. Then, step 128
Then, the score display is returned to the beginning in the same manner as described in step 96 of FIG.

Thereafter, step 1 is performed in the same manner as described above.
After the processes of 20, 122 and 108 are performed, the process returns to the routine of FIG. As a result, the pointer LP is displayed at the start position of the first display section of the selected song in a black solid state.

FIG. 10 shows a subroutine of the switching position SW process. The switching position SW is the header information HD
This is operated when you want to change the switching position that is set according to the switching position data in the start / stop S
The switching position can be changed either before or after starting the music progression by W.

In step 130, SW14a-SW14 of FIG.
The value corresponding to the operated SW of 14d is set in the switching position register CP. For example, in the case of 3/4 beat, 72 is set if the operated switch is SW14a, 36 is set for SW14b, 18 is set for SW14c, and the value of the register LAST is set in the register CP for SW14d.

Next, at step 132, the lit display element LED is turned off, and the display element LED corresponding to the operated SW is turned on. As a result, the newly selected switching position can be confirmed on the display. After that, the process returns to the routine of FIG.

FIG. 11 shows a subroutine of tempo change SW processing. The tempo change SW is operated when it is desired to change the interrupt period (song progression tempo) of the timer 22 set according to the tempo data in the header information HD, and the start / stop SW starts the progress of the song. The interrupt cycle can be changed either before or after the start. The tempo change SW can instruct either tempo up or tempo down.

In step 140, it is determined whether the tempo change SW has instructed the tempo. If this determination result is affirmative (Y), the interrupt period is shortened in step 142, and if it is negative (N), the interrupt period is lengthened in step 144.

When the process of step 142 or 144 is completed, the process proceeds to step 146, and the tempo value TM displayed on the display DPL is changed in accordance with the newly set interrupt cycle. Thereafter, the process returns to the routine of FIG.

FIG. 12 shows a subroutine of the display update process. In step 150, the flag CHGF is set to 1
Determine whether. If the determination result is negative (N), the process returns to the routine of FIG.

When step 150 is first reached after setting CHGF to 1 in step 112 of FIG. 9, the determination result of step 150 is affirmative (Y), and step 1
Move to 52. In step 152, 0 is set in CHGF. This is to enable the next display update.

Next, in step 154, the pointer VA
The musical score image data VD indicated by the PNT is read and the display DP
Display on L. As a result, the display DPL is shown in FIG.
At the timing of the length CP before the end of the display section ZL shown in, the score of the next four measures is displayed instead of the score being displayed. Therefore, the player can know the content of the score to be played next while playing near the end of the score.

In step 156, the pointer SAPNT
To read the note length data LD of the next display section and set it in the register LAST. And step 158
And proceeds to SAPNT to read data. At this time, either the address data AD or the end data ED is read.

Next, at step 160, it is judged whether the read data is the end data ED. If the determination result is negative (N), the process proceeds to step 162, and the read address data AD is set in the pointer VAPNT. As a result, the next score image data can be read.

The determination result of step 160 is positive (Y).
If it is, the flag ENDF is set to 2 in step 164.
Set. When the processing of step 162 or 164 ends, the routine returns to the routine of FIG.
