DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic performance device for executing various functions such as copying and deleting by using a section of performance data defined by two points.

[0002]

2. Description of the Related Art Conventionally, various automatic performance devices have been developed which automatically generate musical tones. In this kind of automatic performance device, performance data based on musical sounds to be generated is stored in advance, and each musical sound is generated in accordance with these performance data. In this case, the event data indicating the pronunciation event for each musical sound is stored together with the timing data indicating the timing that should occur at each event, and the stored timing data is compared with the currently playing timing during the automatic performance. When these match, the event data is read and the pronunciation of each musical sound is controlled.

Some automatic performance devices set a section of performance data by designating two points, a start position and an end position, and using these two points to execute various functions. This function includes, for example, repeat reproduction between two points, copying of performance data between two points, and deletion of performance data between two points.

[0004]

However, in the above-mentioned conventional automatic musical instrument, two points are instructed for each operation mode or each function. For example, in edit mode in which the performance data is modified and edited, two points are specified, the function of copying the performance data between these two points to another position is executed, and then the edit mode is changed to the playback mode in which automatic performance is performed. If the mode is changed once, the mode is changed to the edit mode again and the same 2
In order to copy the performance data between the points to a position different from the last time, the same two points had to be input again.
In edit mode, specify 2 points and
In order to repeat the performance data between the points in the reproduction mode, the same two points had to be input again.

As described above, the conventional automatic performance apparatus has a problem that the operation is very troublesome because it is necessary to re-input two points each time a different function is executed. The present invention has been made in view of the above-mentioned problems, and an object thereof is to provide an automatic performance device with improved and simplified operability.

[0006]

B: Operation of Embodiment Next, the operation of the embodiment having the above-mentioned configuration will be described with reference to FIG.
~ It demonstrates one by one with reference to FIG. In this description of the operation, each routine executed by the CPU 3 will be described separately.

B-1: Operation of Main Routine First, when the power of this device is turned on, the main routine shown in FIG. 3 is started. First, in step Sa1, initialization processing such as zero reset of various registers and flags in the RAM 6 and writing of initial setting values is performed, and, for example, a flag RUN designating ON / OFF of automatic performance is cleared. . When these processes are completed, the process proceeds to the next step Sa2.

In step Sa2, it is determined whether or not each switch (see FIG. 2) of the switch group 8 has been turned on. If ON is not detected here, the determination result is “NO”, and the process immediately proceeds to step S described later.
On the other hand, when it is detected that the switch is ON, the determination result is “YES”, and the process proceeds to the next step Sa3 to determine whether the switch that is turned ON is the RUN / STOP switch 811. It The switch is RU
If it is the N / STOP switch 811, the determination result is “YES”, and the process proceeds to step Sa4 to execute the RUN / STOP switch process described later, while the turned-on switch is the RUN / STOP switch 811.
If not 11, the determination result is "NO", and it is determined in step Sa7 whether or not the value of the flag RUN is "0". Here, the flag RUN specifies whether or not the automatic performance is turned on, and when the value of the flag is "1", the automatic performance is turned on.

When the value of the flag RUN is "0" in step Sa7, the determination result is "YES", and the process (described later) corresponding to each switch turned on in step Sa8 is executed. , Flag RU
If the value of N is "1", the automatic performance is on, so the process immediately proceeds to step Sa5 in order to invalidate the switch that has been turned on.

Next, when the determination result in step Sa2 is "NO", RUN /
When the STOP switch process is completed, step Sa8
In the case where the determination result in step Sa7 is “NO”, the processing proceeds to step Sa5, the automatic performance processing described later is executed, and the step continues. Sa6
In, other processing, for example, key processing and musical tone generation processing corresponding to the depressed key are performed. After the process is completed, the process returns to step Sa2, and thereafter, the processes of steps Sa2 to Sa8 are repeatedly executed until the power is turned off. Thus, in the main routine, the automatic performance process, the switch process corresponding to the setting of the switch group 8 and other processes are executed.

In this embodiment, the timer interrupt process shown in FIG. 4 is performed separately from the main routine described above. This interrupt process is activated every period corresponding to the tempo of the automatic performance, and indicates the automatic performance process timing of step Sa5 in the main routine. For example, it is activated every 24th quarter note. . As a result, the automatic performance process of step Sa5 in the main routine is executed for each period according to the tempo.

B-2: Switch Correspondence Processing (Step Sa8) Next, the switch correspondence processing in step Sa8 of the main routine will be described in detail for each switch. This corresponding process is executed only when the automatic performance is not on, that is, when the value of the flag RUN is "0". In addition, in this handling process, the contents of each register and flag mainly correspond to each switch of the switch group 8 (see FIG. 2).
It is changed and set according to the operation.

B-2-1: Processing of Position Moving Switches 801 to 803 When any of the position moving switches 801 to 803 is pressed, it is shown in FIG. 5 in step Sa8 of the main routine (see FIG. 3) described above. The subroutine is executed. In this routine, the value of the register is reset and the display of the value is changed corresponding to the measure number specified by the switch.

Next, this routine will be described in detail. First, when the position movement switch 801 is pressed, "1" is set in the register MEAS in step Sb1. When the position movement switch 802 is pressed, the value of the register MEAS is decremented by "1" in step Sb2. On the other hand, when the position movement switch 803 is pressed, the value of the register MEAS is incremented by "1" in step Sb3.
Here, the register MEAS is a register in which a measure number is stored. That is, the bar number at the moment is
At the beginning of the song in step Sb1, 1 in step Sb2
One is moved forward, and one is moved backward in step Sb3.

When a value is set in the register MEAS in any of steps Sb1 to Sb3, the head address where the performance data of the measure number indicated by the register is stored is set in the register AD (step Sb).
4), “MEAS =” on the display screen G (see FIG. 2)
The right side of the display is changed to the current value of the register MEAS (step Sb5), this routine ends, and the processing returns to the main routine (see FIG. 3). In this way, by operating the position movement switches 801-803, it is possible to arbitrarily specify the bar number (position) of the music.

B-2-2: Processing of Position Designating Switches 804 and 805 When the position designating switch 804 or 805 is pressed,
Step Sa8 of the main routine (see FIG. 3) described above
At, the subroutine shown in FIG. 6 is executed. First, when the position designation switch 804 is pressed, the process proceeds to step Sc1 and the value of the register MEAS is set in the register A. Here, the register A is a register for storing the measure number A of the section start of the automatic performance data.

Subsequently, the head address where the performance data of the register MEAS (the measure number indicated by the value of) is stored is set in the register ADA (step Sc2),
The right side of “A =” on the display screen G (see FIG. 2) is changed to the current value of the register MEAS (step Sc3), and it is determined whether the value of the register A is the value of the register B or less. (Step Sc4). If the determination result is "YES", this routine ends, but if the determination result is "NO", the process proceeds to step Sd1 described later. This is to prevent the bar number A at the start of the section from becoming larger than the bar number B at the end of the section.

Similarly, when the end position designation switch 805 is pressed, the step processing proceeds to step Sd1 and the value of the register MEAS is set in the register B. Here, the register B is a register for storing the bar number B of the section end of the automatic performance data. Continue to register M
The final address where the performance data of EAS (the bar number indicated by the value of EAS) is stored is set in the register ADB (step Sd2), and the right side of "B =" on the display screen G (see FIG. 2) is the current time. The display is changed to the value of the register MEAS (step Sd3), and it is determined whether or not the value of the register B is greater than or equal to the value of the register B (step Sd4). If this determination result is "YES", this routine ends, but if the determination result is "NO", then the process proceeds to step Sc1 described above.

Here, the processing proceeds from step Sc4 to step Sd1 or from step Sd4 to step Sd.
Register MEA at the current time when the route to c1
Since the value of S is set in registers A and B respectively,
The values of register A and register B are equal to each other.
In this case, the section of the set automatic performance data is only one bar.

In this way, when the values A and B satisfying A ≦ B are set in the registers A and B, respectively, this routine ends, and the process returns to the main routine (see FIG. 3). That is, A and B are initialization processing (step Sa in the main routine).
It is not changed except for the processing of 1) and steps Sc1 and Sd1. Therefore, even if the function is changed, the values of the registers A and B are stored as they are.

B-2-3: Processing of COPY Switch 806 When the COPY switch 806 is pressed, in step Sa8 of the main routine (see FIG. 3) described above, FIG.
The subroutine shown in (a) is executed.

First, the copy mode is turned on (step Se1), and the delete mode is turned off (step S1).
e2). This is done, for example, by setting flags corresponding to the copy mode and the delete mode.
After this, "COP" is displayed at the bottom right of the display screen G (see FIG. 2).
The display "Y" is turned on, and the operator is informed that the copy mode is on (step Se3). If the delete mode was on before this routine was started, the display "DELETE" is extinguished. Then, after the processing of step Se3, this routine ends, and the processing returns to the main routine (see FIG. 3).

B-2-4: Processing of DELETE Switch 807 When the DELETE switch 807 is pressed, in step Sa8 of the main routine (see FIG. 3) described above,
The subroutine shown in FIG. 7B is executed.

First, the delete mode is turned on (step Sf1), and the copy mode is turned off (step Sf1).
f2). After that, the display "DEL" is lit in the lower right part of the display screen G (see FIG. 2) to inform the operator that the delete mode is on (step Sf).
3). If the copy mode is on before this routine is activated, the display "COPY" is extinguished. Then, after the processing of step Sf3, this routine ends, and the processing returns to the main routine (see FIG. 3).

B-2-5: Processing of ENTER Switch 808 When the ENTER switch 808 is pressed, the subroutine shown in FIG. 8A is executed in step Sa8 of the main routine (see FIG. 3) described above. First, in step Sg1, it is determined whether or not the copy mode is currently set. If the determination result is “NO”, the process proceeds to step Sg3, while if the determination result is “YES”, the process proceeds to the next step Sg2.

At step Sg2, the data after the bar number corresponding to the value of the register MEAS at the present time is
The performance data of the section defined by the registers A and B is copied in the empty portion of the performance data generated by this movement while moving to the rear of the music by the number of measures defined by the registers A and B. At this time, the bar number in the performance data moved backward is incremented and rewritten by the number of copied bars, and the register A,
When the measure number stored in B is larger than the measure number stored in the register MEAS, the measure numbers stored in the registers A and B are also rewritten by incrementing the number of copied measures. That is, the performance data after the address (stored in the register AD) is moved backward by the address (AD + 1-ADA), and the space between the addresses (the value of the register ADA ~ Value of register ADB)
The performance data of is copied. When step Sg2 ends, this routine ends.

On the other hand, in step Sg3, it is further determined whether or not the delete mode is on. The case where the determination result is “NO” is the case where the ENTER switch 808 is pressed even though neither the copy mode nor the delete mode is specified, so no processing is performed. Without returning, immediately return to the main routine. If the determination result of step Sg3 is “YES”, the process proceeds to next step Sg4.

In step Sg4, the performance data corresponding to the bar section from the bar number set in the register A to the bar number set in the register B is deleted, and a blank part of the data generated by this deletion is generated. The performance data in the rear is moved forward so as to fill in. That is, performance data between addresses (value of register ADA to value of register ADB) is deleted. Also,
At this time, the bar number in the performance data moved forward is decremented by the deleted bar number and rewritten, and the bar number set in the register A is set in the register B. When the process of step Sg4 ends, this routine ends, and the process returns to the main routine (see FIG. 3).

B-2-6: Processing of EXIT Switch 809 When the EXIT switch 808 is pressed, in step Sa8 of the main routine (see FIG. 3) described above,
The subroutine shown in (b) is executed. First, in step Sh1, both the copy mode and the delete mode are turned off. Then, in step Sh2, "COPY" or "D" that is lit in the lower right part of the display screen G
The display "EL" is extinguished, and this routine ends.

B-2-7: Processing of REPEAT Switch 810 When the REPEAT switch 810 is pressed, in step Sa8 of the main routine (see FIG. 3) described above,
The subroutine shown in FIG. 9 is executed. First, in step Si1, if the repeat mode is off, it is turned on, and if it is on, it is turned off. this is,
For example, it is performed by setting a flag corresponding to the repeat mode and inverting the flag. Subsequently, in step Si2, the display "REPEAT" at the lower right of the display screen G is turned on / off in correspondence with ON / OFF of the repeat mode. Step S
When the process of i2 ends, this routine ends, and the process returns to the main routine (see FIG. 3).

B-3: RUN / STOP switch 8
Process 11 (step Sa4) RUN / ST regardless of whether automatic performance is on or off
When the OP switch 811 is pressed, the subroutine shown in FIG. 10 is executed in step Sa4 of the main routine (see FIG. 3). In this routine, in order to start or stop the automatic performance by pressing the switch,
Various data are set in various registers.

First, in step Sj1, the flag R
It is determined whether or not the value of UN is "0", that is, whether or not the automatic performance is off. If the automatic performance is on, the determination result is "NO", and the flag is set to "0" to stop the automatic performance (step Sj
9) While this routine is immediately ended, if the automatic performance is off, the determination result is "YES", the flag is set to "1" to immediately start the automatic performance (step Sj2), and the register CLK is set. "0" is set (step Sj3), and the process proceeds to the next step Sj4. Here, the register CLK indicates the timing within a bar in the automatic performance, and its value is incremented in the automatic performance processing described later. The case where the value of the register CLK is "0" means that the timing within the bar of the automatic performance at the present time is located at the beginning of the bar (bar line timing), and the value of the register is "MAX". The case is when the timing within the bar is located at the end of the bar.

Next, at step Sj4, it is judged if the repeat mode is set or not. Step S in FIG.
When the repeat mode is designated to be off in i1, the determination result is “NO”, and the process is step S
If the read pointer is set to the value of the register AD in order to read the performance data (of the bar number indicated by the value) of the register MEAS at the present time, the routine ends, and the repeat mode is on. Process, the process proceeds to the next step Sj5.

Next, in step Sj5, the value of the register A is set in the register MEAS, and subsequently, in step Sj6, the read pointer is set to the register AD in order to read the performance data corresponding to the measure number A at the start of the section.
It is set to the value of A, and further, in step Sj7, the right side of "MEAS =" of the display screen G (see FIG. 2) is changed to the current value of the register MEAS (register A). When the process of step Sj7 ends, this routine ends, and the process returns to the main routine (see FIG. 3).

In this way, the RUN / STOP switch 8
When 11 is pressed, the value of the flag RUN is set to "0" if the automatic performance is on, while the value of the flag RUN is set to "1" if the automatic performance is off. In addition, in correspondence with ON / OFF of repeat mode,
The read pointer is set to the address of the performance data to be read. As described above, when the contents of the registers and flags required for automatic performance are set, thereafter, musical tones are generated by the automatic performance processing described below.

B-4: Automatic Performance Processing (Step Sa5) When the processing reaches step Sa5 of the main routine shown in FIG. 3, the automatic performance processing shown in FIG. 11 is executed. As described above, this automatic performance process is executed according to the timing instruction by the timer interrupt process. This automatic performance process is roughly divided into a sound generation process when the timing in the automatic performance coincides with the timing at which the performance data should be read out, an increment process of the intra-measure timing, and a repeat mode in preparation for the next execution. The read pointer is set in correspondence with the ON / OFF state of.

Next, the automatic performance process will be described in detail. First, when this routine is activated, it is determined in step Sn1 whether or not the value of the flag RUN is "1". If the result of this determination is “NO”,
This routine ends immediately. This automatic performance process
This is because it is unnecessary if automatic performance is not instructed. On the other hand, if the determination result is “YES”, the process proceeds to step S
In n2, it is determined whether or not it is the processing timing. Here, the processing timing means that after the automatic performance processing timing is instructed in the timer interrupt processing,
This is the case when this process is entered for the first time. That is, 2
After the first time, the following processing is not executed until the next instruction is given.

When it is not the processing timing, the determination result is "NO", the routine immediately ends and returns to the main routine to prepare for the next startup. On the other hand, if it is the processing timing, the determination result is “YES”, the processing proceeds to step Sn3, and if there is performance data corresponding to the current values of the registers MEAS and CLK, the performance data is read and is sent to the tone generator circuit 7. Supplied. As a result, the sound based on the performance data is produced by the sound system SS.
Done by

After this tone generation processing, in step Sn4, it is determined whether or not the value of the register CLK is the maximum value.
That is, it is judged whether or not the timing within the bar at the present time is the end of the bar. If this determination result is "NO", the register CLK is moved to the timing within the next bar.
Is incremented by 1 (step Sn14),
While this routine ends, if the current intra-bar timing is located at the end of the bar, the determination result is "Y.
After "ES" and the register CLK is cleared (step Sn5), it is determined whether or not the repeat mode is set (step Sn6).

If the determination result is "NO", the process proceeds to step Sn11 described later, while if the determination result is "YES", the process proceeds to the next step Sn7 and the value of the register MEAS is changed. It is determined whether or not it is equal to the value of the register B. That is, it is determined whether or not the automatic performance progressing bar at the present time is the bar number B of the section end set by the position specifying switches 804 and 805 (see FIG. 2). If the determination result is “NO”, the process proceeds to step Sn11. On the other hand, if the determination result is “YES”, the value of the register A is set to the register MEAS so as to repeat from the measure number A of the section start.
Is set to (step Sn8), the read pointer is set to the value of the register ADA (step Sn9) to read the performance data of the measure (step Sn9), and the process proceeds to the next step Sn10.

Next, at step Sn10, the value of the register MEAS at the present time is displayed on the display screen G (see FIG. 2).
The display is changed to the right side of “MEAS =” in, and this routine ends.

On the other hand, if the processing shifts to step Sn11, that is, if the determination result of step Sn6 or Sn7 is "NO", the value of the register MEAS is incremented by "1" to shift to the next bar. It After this processing, the processing proceeds to step Sn12, and it is determined whether or not there is performance data after the current timing within the bar, and it is determined whether or not the performance has ended. If the determination result is "NO", the process proceeds to step Sn10 described above to change the display of the measure number, while if the determination result is "YES", the flag RUN is set to "0" to end the automatic performance. After is set,
This routine ends and the main routine (see Figure 3)
Return to step Sa8.

In the above-described embodiment, the function of using the section performance data set by the section start measure number A and the section end measure number B is COPY, DELET.
Although E and REPEAT are used, any function such as movement of section performance data or uniform correction of section performance data may be used. Further, in the above-described embodiment, the section of the performance data is designated in units of bars for convenience of explanation, but the present invention is not limited to this. That is, it may be specified for each beat within a bar, or may be specified for each clock (the execution cycle of the automatic performance process) which is the minimum time unit of the embodiment. Also, so-called pattern sequence data or chord progression data, which specifies the storage order of performance pattern data of several measures from "1" separately stored as performance data, may be applied to the present invention.

According to the present invention described above, the first
Once you have specified once the start and end positions by a preliminary second designating means, the second storage means stores the start and end positions, the start position for each selected by the function selection means different functions and There is no need to specify the ending position. Therefore, the operating procedure is reduced and the operability is improved. Also, once the start or end position is
If it is specified again after being set, the control means
If the start position is behind the end position,
End position is the last position in the specific unit that contains the start position
Changed or the end position is before the start position
If the start position is
It is changed to the first position in the rank. Therefore, the operator can set the start position and the end position without worrying about the positional relationship between them. Further, since the position setting does not contradict the start and end, malfunction can be prevented.
