FIG. 9 is a flowchart of a main routine of a control program processed by the CPU 1, and FIGS. 10 to 14 are flowcharts of a subroutine and an interrupt processing routine. The operation of the embodiment will be described based on each flowchart. In addition, in the following description and each flowchart, each flag and register of the working memory 3 are represented by the following labels, and their stored contents are represented by the same label unless otherwise specified.

MOD: A flag indicating a mode of whether or not to guide the key depression instruction for each of the right hand and the left hand. RUN: A flag indicating start / stop of automatic performance. CH: A register of the channel number of the allocated channel of the sound source 10. GT (CH): Gate time register for CH channel. TR: Register of track number of performance information. TM (TR): TR track duration time register. KC: A register of the key code of the key instructing the key depression.

When MOD = 0, the flag MOD "does not guide left and right", when MOD = 1 "guides only right hand", when MOD = 2 "guides only left hand", and when MOD = 3 Each of the modes "guide left and right" is shown, and the flag RUN shows each mode of "automatic performance stop" when RUN = 0 and "automatic performance start" when RUN = 1.

Further, in this embodiment, the key code list is used to hold the key code of the same timing for instructing the key depression read from the performance information at the time of automatic performance. This key code list is also used as a working memory. It is composed of a plurality of three registers.

When the processing of the main routine shown in FIG. 9 is started by turning on the power, initial setting such as resetting each flag and register is performed in step S1, and presence or absence of a key event in the keyboard 4 is determined in step S2. If there is not, the process proceeds to step S7, and if there is a key event, it is determined in step S3 whether or not it is a key-on event.

If it is not the key-on event, it is the event of releasing the key. Therefore, the mute processing is performed in step S4 and the process proceeds to step S7.
In step S6, the tone generation process is performed, and in step S6, the comparison progress process of FIG. 11 described later is performed, and the process proceeds to step S7.

In step S7, it is determined whether or not there is an on event of the load switch. If there is no on event, the process proceeds to step S9. If there is an on event, the performance information stored in the disk 5 is read out in step S8 and the performance is performed. The data is written in the information memory 6, and the process proceeds to step S9.

In step S9, it is determined whether or not there is an on event of the mode changeover switch. If there is no on event, the process proceeds to step S11. If there is an on event, the current value of the flag MOD is 0 → 1 → in step S10. 2 → 3 →
One is switched and updated in the order of 0, and step S11
Proceed to. As a result, the mode of the key depression instruction guide is switched every time the mode changeover switch is operated.

In step S11, it is determined whether or not there is an on event of the start / stop switch. If there is no on event, the process proceeds to step S16. If there is an on event, the flag RUN is inverted in step S12 and RUN is executed in step S13. It is determined whether or not = 1.

If RUN = 1 is not satisfied (RUN =
0), the stop is instructed in the automatic performance state, so the automatic performance stop processing is performed in step S14 and the process proceeds to step S16. If RUN = 1, the start of the automatic performance is instructed. Therefore, the automatic performance start process of FIG. 10 is performed in step S15, and the process proceeds to step S16. Then, in step S16, other processing such as tone color selection is performed, and the processing from step S2 onward is repeated.

In the process of the main routine described above, steps S2 to S6 are processes of sounding and muting a key event on the keyboard 4. Further, as will be described later, the comparison progress process of step S6 when the key is turned on is a process of checking whether or not the key instructed to press the key is pressed, and all the keys instructed to press the key are pressed. Waits until all keys of the key depression instruction are pressed, and the wait state is released. As a result, the progress of automatic performance and fingering display by interrupt processing is controlled.

Steps S7 and S8 are processes for loading performance information of music, and steps S9 and S10.
Is a process for setting the mode of the key pressing instruction guide, and steps S11 to S15 are processes for starting and stopping the automatic performance. Therefore, it can be considered that after the automatic performance is started, the processes of steps S2 to S6 and step S16 and the interrupt process are substantially repeated.

First, the automatic performance start process of FIG. 10 will be described. In this automatic performance start process, the read pointers of all tracks are set to the heads of the storage areas corresponding to the respective tracks of the performance information memory 6 in step S21. It is set and the waiting state is released in step S22.

Next, in step S23, the track number = 0
~ Duration Time TM for all 8 tracks
(L) (L = 0 to 8) is reset to "0", and the tone generation key code list is cleared in step S24. Next, at step S25, the key data having the closest sounding timing after the address indicated by the read pointer of each track of track number = 0 and track number = 1, that is,
The key data of the sound to be sounded first is read out.

Then, in step S26, the red LED 84 corresponding to the key 41 of the key code of the read key data.
Flashes and returns to the main routine. This completes the initial setting of automatic performance. It should be noted that the read pointer is not updated when reading the key data to be sounded first.

In the comparison progress processing of FIG. 11, step S3
In 1 it is determined whether or not it is in the waiting state. If it is not in the waiting state, the routine returns to the original routine. If there is any key not pressed, the process returns to the original routine.

If all the key codes in the sounding key code list are pressed, the current key pressing instruction guide becomes unnecessary. Therefore, in step S33, the red LED 84 corresponding to the key of the key code in the sounding key code list is turned on. The light is turned off, the waiting state is released in step S34, and step S35
Then, the pronunciation key code list is cleared and the process proceeds to step S36. By the above steps S33 to S35, the waiting state is released when all the keys instructed to be pressed are released. Therefore, as will be described later, automatic performance and fingering display are performed in the interrupt process. become.

In step S36, MOD = 1 or M
It is determined whether or not OD = 3, and MOD = 1 and MOD =
If neither of the three, proceed to step S39, MOD
= 1 or MOD = 3, step S3
7 is performed. In step S37, for the track with the track number “0”, that is, the track for the right hand,
After the address indicated by the read pointer, all the key data at the same timing of the key data having the closest sounding timing is read, and in step S38, the red LED 84 corresponding to the key of the key code of the read key data blinks, and step S39. Proceed to.

In step S39, MOD = 2 or M
It is determined whether or not OD = 3, and MOD = 2 and MOD =
If neither of the three, return to the original routine, MOD
= 2 or MOD = 3, step S3
01 processing is performed. In step S301, for the track with the track number "1", that is, the left-hand track, all the key data at the same timing of the key data having the closest sounding timing after the address indicated by the read pointer are read, and in step S302, this reading Red LED 8 corresponding to the key of the key code of the key data
Flashes 4 and returns to the original routine.

By the processes of steps S36 to S38, the key 41 to be pressed next with the right hand corresponds to the key pressing instruction guide for the right hand when MOD = 1 and MOD = 3. It is instructed by blinking the red LED 84. Similarly, steps S39 to S30.
By the processing of 2, the key 41 to be depressed next with the left hand is designated by blinking the corresponding red LED 84, corresponding to the key depression instruction guide for the left hand when MOD = 2 and MOD = 3.

The interrupt processing shown in FIG. 12 is activated every 96 minutes by an interrupt signal from the timer 9, and performs fingering display processing and automatic performance sounding and muting processing in time with the current interrupt processing timing. First, in step S41, RUN =
If RUN = 1, it returns to the original routine. If RUN = 1, it is determined in step S42 whether it is in the waiting state. Then, if it is in the waiting state, the process returns to the original routine as it is in order to wait for the operation of the automatic performance and fingering display, and if it is not in the waiting state, the processing of the automatic performance and the fingering display is performed after step S43.

In step S43, the reproduction process of FIG. 13 described later is performed, and then in step S44, the comparison progress process of FIG. 11 is performed. Here, the reproduction process of step S43 includes a process of detecting the key data (key code of the key to be depressed) at the timing of this interrupt process from the track which is the target of the right hand and left hand key depression instruction guides. When the key data is detected, a key depression instruction guide is given to release the waiting state. Therefore, the comparison progress process is performed in step S44 immediately after the key depression instruction guide is given.

Further, as will be described later, step S4
Since the gate time is stored in the register GT (CH) of the channel when the automatic performance is sounded in the reproduction processing of No. 3, the mute processing is performed based on this gate time in step S45 and thereafter. That is, the register CH of each channel number of the sound source is set to "0" in step S45, and the processing from step S46 onward is repeated for 16 channels by the increment of CH in step S49 and the determination processing in step S401.

First, in step S46, GT (CH) ≤
It is determined whether or not 0, and if GT (CH) ≦ 0 is not satisfied, the current timing is not muffling.
Decrement T (CH) by 1 and proceed to step S49. If GT (CH) ≦ 0, the current timing is for muffling, so in step S48, the channel number CH and key-off signal are output to the sound source 10 to mute Then step S
Proceed to 49. Then, in step S, step S401, C
If H = 16, the processing is completed for 16 channels, and the process returns to the original routine.

The reproduction process shown in FIG. 13 is a process for displaying fingering and playing an automatic performance based on the performance information in the performance information memory 6. First, in step S51, the track number TR of the performance information is set to "0". By the increment of TR in step S506 and the determination process of step S507,
The processing from step S52 is repeated for the 9th track.

In step S52, it is determined whether or not TM (TR) ≤0. If TM (TR) ≤0 is not satisfied, the currently focused track is not the sounding timing. Therefore, in step S53, the duration time TM (TR) is set. ) Is decremented by 1 and the process proceeds to step S506. If there is a next track, the next track is processed.

On the other hand, TM (TR) ≤0 in step S52.
If so, the track currently being watched is the sound generation timing or the end, so in step S54 the data pointed to by the read pointer of the track TR currently watched is read, and the read pointer is set to the next data. Proceed to S55.

In step S55, it is determined whether the read data is end data. If it is end data, the process proceeds to step S506. If it is not end data, it is determined in step S56 whether it is duration data. . If it is duration data, there is no more data corresponding to the current timing on the currently focused track, so the duration time is stored in the register TM (TR) in step S57, and step S5 is executed.
In step 06, if there is a next track, the next track is processed.

If it is not duration data in step S56, it is determined whether it is key data in step S58. If it is key data, the key-on process of FIG. 14 is performed in step S59. If it is not key data, it is determined in step S501 whether it is LED lighting data,
If it is LED lighting data, the green LED (81, 82, 83) corresponding to the LED number is lit in step S502,
If it is not the LED lighting data, the LED is detected in step S503.
It is determined whether or not it is the extinguishing data, and if it is the LED extinguishing data, the green LE corresponding to the LED number in step S504.
Turn off D (81, 82, 83). If it is not the LED turn-off data, other processing is performed in step S505.

Key-on process in step S59, LED lighting process in step S502, LED in step S504
After the turn-off processing and the other processing of step S505 are completed, there is a possibility that data corresponding to the current timing still exists in the currently focused track, so the procedure proceeds to step S54, and the same applies to the currently focused track. Process. Then, in step S507, TR = 9
When it becomes, it means that the processing for all the tracks has been completed in one interrupt processing, so that the routine returns to the original routine.

The above reproduction processing is started at the timing of interrupt processing, and for the track whose current interrupt processing timing is during the duration time, that is, between the sounds to be sounded, the duration time is one clock. For the track whose current timing is the sound generation timing, the key-on process of FIG. 14 and the finger position guide by the green LEDs 81, 82, 83 are performed.

In the key-on processing of FIG. 14, step S6
1 for "(MOD = 1 or 3 & TR = 0) or (M
OD = 2 or 3 & TR = 1) "is satisfied, and if the condition is satisfied, the process from step S62 is performed, and if the condition is not satisfied, the process from step S66 is performed.

At step S62, step S of the reproduction process is performed.
The key code of the key data read in 54 is stored in the register KC, and the key code KC is added to the sounding key code list in step S63.
