BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic performance device for automatically performing a performance pattern designated on the basis of performance information of a plurality of performance patterns stored in a memory.

[0002]

2. Description of the Related Art Conventionally, as an automatic performance device of this kind, performance information of a plurality of accompaniment types (styles) according to a style of music such as rock and bossa nova is stored, and the accompaniment type is designated by an operator or the like. Therefore, there is an automatic performance device that can automatically perform a desired accompaniment type.

Further, each accompaniment type is associated with a style number as identification information, and the performer identifies the current accompaniment type by displaying the style number of the designated accompaniment type on a display or the like. can do.

By the way, in such an automatic accompaniment apparatus,
The accompaniment type can be specified and changed even during automatic accompaniment. However, if the operator is operating while playing another instrument, etc., the operator must change the accompaniment type earlier than when switching the accompaniment type. Since it has good operability, it is often specified and changed in the middle of a bar.

Therefore, even in such a case, in order to smooth the connection of the performances, the accompaniment type to be actually played should be changed from the position of the next beat after the designation / change and the start of the next bar. ing.

[0006]

However, in the conventional apparatus, even when the accompaniment type is designated or changed during the automatic performance, the style number is displayed at the beginning of the next bar or the like. If you specify or change without waiting, it will be switched and displayed immediately.

For example, as shown in FIG. 8, if the automatic performance of the style number "01" is performed and the accompaniment of the style number "02" is designated / changed at the timing t ₁ in the middle of the measure, the measure but is switched from the timing t ₂ of the head to the automatic performance of the style number "02", style number that is displayed on the display device is, will change to "02" from "01" at the time t ₁ for which the designation and change ..

For this reason, the performer has style number "0.
During Δt, which delays the automatic performance of 2 ”, the currently played accompaniment type does not match the currently displayed style number, so it is confusing or the currently played accompaniment type is different. It was sometimes misunderstood, and the usability when switching performance patterns was poor.

The present invention specifies the accompaniment type during automatic performance.
An object of the present invention is to provide an automatic performance device which is easy to use and easy to handle even when changed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram of an electronic musical instrument to which an automatic musical instrument according to an embodiment of the present invention is applied. This electronic musical instrument is a CPU.
The designated style number is displayed on the display unit 3 by controlling (1) and designating (inputting) the accompaniment style number of the automatic performance with the panel switch 2. Also, CP
U1 reads the chord sequence data and the accompaniment data corresponding to the style number from the performance information memory 4 and performs automatic performance.

Further, when a new accompaniment style number is specified during automatic performance, the new accompaniment style number is displayed blinking on the display unit 3, and the automatic performance for the accompaniment style numbers up to that point is completed at the end of the bar. It continues until (until the beginning of the next bar), and the automatic performance for the new accompaniment style number is awaited. Then, when the standby state ends, the new accompaniment style number is lit and the automatic performance for the new accompaniment style number is started following the automatic performance up to that point.

The electronic musical instrument of this embodiment is an electronic drum provided with a pad 5 as an operator for playing a drum and a pad event detection circuit 5a. Generate percussion instrument sounds in the set.

The panel switch 2 includes a numeric keypad 21 for inputting an accompaniment style number for automatic performance, a start / stop switch 22 for instructing start and stop of automatic performance, a tempo switch for setting the tempo of automatic performance, etc. The switch event detection circuit 2a includes other switches (not shown).
Detects an event of a switch operation in and generates a signal corresponding to the detected switch.

The display 3 is composed of a 2-digit 7-segment LED driven by the driver 3a, and displays accompaniment style numbers and the like for automatic performance according to the display data input from the CPU 1 to the driver 3a. It

The program memory 6 stores a control program whose flowcharts are shown in FIGS. 2 to 6, and the CPU 1 has various registers and flags set in the working memory 7 based on the control program of the program memory 6. Control while using.

The tempo clock generation circuit 8 generates a tempo clock for each eighth beat (one beat is one quarter note) at a timing according to the tempo value set by the CPU1, and the CPU1 uses this tempo clock. Performs interrupt processing to control the tone generation of the automatic performance. Also, timer 9
Generates an interrupt clock every 1 second, and the CPU 1 performs timer interrupt processing by this interrupt clock to measure a predetermined time.

The tone generator (TG) 10 has a plurality of tone generation channels, and the CPU 1 controls the tone generation by allocating the channels of the tone generator 10 and outputting the data of the musical tone to be sounded to the assigned channels.

Then, the sound source 10 reads out waveform data of a predetermined tone color from a tone waveform memory (not shown) according to the data input from the CPU 1 and outputs a tone signal having a pitch corresponding to the input data to the sound system (SS) 11. Then, the sound system 11 performs D / A conversion, amplification, etc., and produces a musical tone of an automatic performance or a musical tone of a percussion instrument.

In this embodiment, performance patterns of 4/4 time signature and 3/4 time signature are set according to the accompaniment style of the automatic performance, and the flag BT (STYL) having the accompaniment style number STYL as an index is set. Accordingly, the number of clocks of one bar is set (S22 in FIG. 6, which will be described later).

FIG. 2 shows the main routine of the control program,
3 to 6 are flowcharts showing a subroutine and an interrupt processing routine, and the operation will be described based on each flowchart.

In the following description and each flowchart, each register and flag used for control are represented by the following label, and each register and flag and their contents are represented by the same label unless otherwise specified.

INT: register of input value by one key of numeric keypad STYL: register holding accompaniment style number during automatic performance NSTYL: register holding input accompaniment style number TM: counting waiting time of input operation Counter CLK: Counter that counts the automatic performance clock in units of two measures LEN: Register that holds the number of clocks corresponding to one measure N: Flag RUN that controls input switching between the 10th digit and 1st digit of the accompaniment style number : Run flag indicating the start / stop of automatic performance SW: Flag indicating the standby state of automatic performance for the accompaniment style number input during automatic performance

First, when the CPU 1 starts the processing of the main routine of FIG. 2 by turning on the power source or the like, step S1
Then, initial setting such as resetting each flag and register and setting a preset value of tempo in the tempo clock generation circuit 9 is performed, and in step S2, it is determined whether or not there is a pad-on event in the pad 5.

If there is no pad-on event in step S2, the operation proceeds to step S4. If there is a pad-on event, the percussion instrument sound is controlled in step S3, and the operation proceeds to step S4.

In step S4, it is determined whether or not the start / stop switch 22 has an on event. If there is no on event, the process proceeds to step S6. If there is an on event, the start / stop process of FIG. 5 is performed in step S5. Go to step S6.

In step S6, it is determined whether or not there is an on-event in the ten-key pad 21, and if there is no on-event, the processes in and after step S2 are performed as they are. If there is an on-event, the ten-key process shown in FIG. The processing after S2 is repeated.

In the ten-key processing S7 of FIG. 3, first,
At step S71, the number entered with the numeric keypad is now 1.
A flag N indicating whether it is a digit of 0 or a digit of 1 is determined, and if N = 0, that is, if the digit of 1 is input, the process proceeds to step S76, and if N = 0, that is, ,
If 10 digits have been input, the number (one digit number) of the key operated in step S72 is stored in the register INT, and in step S73 the currently input number is multiplied by 10 and stored in the register NSTYL.

Next, in step S74, 1 of the indicator 3 is displayed.
Numerical value INT is displayed in the 0 digit and the 1 digit is extinguished. In step S75, the flag N is set to "1" and the counter TM for counting the waiting time of the input operation is reset to "0", Return to the main routine.

If the determination N = 1 in step S71, the number of the key operated in step S76 is set in the register INT.
Then, the accompaniment style number (00 to 99) is determined by calculating the value of NSTYL + INT in step S77, and the value is stored in the register NSTYL. In step S78, it is determined whether or not the automatic performance is currently being performed.

Since the flag RUN is set to "1" in the start state of the automatic performance and "0" in the stop state by the start / stop processing in step S5 as described later, RUN = 1 If not, input processing is performed while the automatic performance is stopped in step S79 and subsequent steps, and R
If UN = 1, the input process is performed when the accompaniment style is changed and input during the automatic performance in step S702 and thereafter.

That is, in step S79, NSTYL
Is stored in the register STYL, and in step S701, the numerical value INT is turned on at the 1st digit of the display 3 to complete the display of the input accompaniment style number, and the process returns to the main routine.

In step S702, the flag SW is set to "1" to indicate that a new accompaniment style number has been input during the automatic performance, that is, a style change instruction has been issued and is currently on standby. The value is stored in the SW, and in step S703, the numerical value INT is displayed in the first digit of the display unit 3 to complete the display of the accompaniment style number, and the entire display of the display unit 3 is blinked, and the process returns to the main routine.

Accordingly, when the accompaniment style change is instructed during the automatic performance, the instructed accompaniment style number is displayed on the display 3 in a blinking state.

The timer interrupt processing S10 of FIG.
It is activated at an interval of 1 second by the interrupt clock from step S11, and it is determined in step S11 whether or not a numerical value has been input / displayed in the tenth digit of the display unit 3 in step S72 and subsequent steps of the ten-key processing S7. By this interrupt processing, the process returns to the interrupted original routine, and if N = 1, the counter TM is incremented in step S12, and in step S13, the ten-digit number is input and then the numeric keypad operation is not performed. Whether or not seconds have passed, that is, TM = 5
Or not.

If TM = 5 is not reached in step S13, the routine returns to the original routine, and if TM = 5, it is determined that the style changing operation has been canceled, and in step S14 the flag N is reset to "0", In step S15, the accompaniment style number STYL up to that point is lit again on the display device 3 to return to the original routine.

When an instruction is made to change the accompaniment style during the automatic performance, the input processing of the digit of 10 and the digit of 1 is performed in the same manner as described above. The stored accompaniment style number is switched to the blinking display.

In the start / stop processing S5 shown in FIG.
In step S51, the flag RUN is inverted and then in step S5
It is determined whether or not RUN = 0 in 2 and RUN = 0.
In this case, since the stop is instructed in the automatic performance state, the accompaniment channel of the sound source 10 is muted in step S54 and the process returns to the main routine.

On the other hand, in the determination of step S52, RUN = 0
If not (RUN = 1), it means that the start of the automatic performance has been instructed. Therefore, in step S53, the flag SW,
N and the counter CLK are reset to "0" to return to the main routine. With this RUN = 1, the automatic performance is started by the tempo clock interrupt processing.

The tempo clock interrupt processing 20 of FIG.
It is activated every 1/8 beat by the tempo clock from the tempo clock generation circuit 9, and first, RUN is performed in step S21.
= 1 is determined and if RUN = 1 is not satisfied, the process returns to the original routine, and if RUN = 1, step S2
In step 2, the time signature corresponding to the current accompaniment style number is determined by the flag BT (STYL).

In step S22, BT (STYL) = 1
If so, since it is 3/4 beat, in step S23, the number of clocks of one bar "24" (3 beats of 8 clocks per beat) is set in the register LEN, and the process proceeds to step S25 where BT (STYL) = If it is 0, the time is 4/4, so in step S24, the number of clocks in one bar is "32" (1
(4 beats of 8 clocks per beat) are set in the register LEN and the process proceeds to step S25.

In step S25, the flag SW is determined,
If SW = 1 is not instructed to change the accompaniment style during the automatic performance, normal automatic performance is performed after step S202. If SW = 1, the accompaniment style change during the automatic performance is performed. Because it is instructed,
In step S26 and subsequent steps, a process of waiting for automatic performance of the changed accompaniment style number is performed.

That is, in step S26, CLK = 0
Alternatively, it is determined whether or not the condition of CLK = LEN is satisfied, and if neither condition is satisfied, the current timing (clock) of the automatic performance is not at the beginning of the bar on the musical score, so it is changed after step S202. The automatic performance of the accompaniment style number up to that point is continued.

On the other hand, if either CLK = 0 or CLK = LEN is satisfied in step S26, the current timing of the automatic performance is at the beginning of the bar, so in step S27, the changed accompaniment style number NSTYL. Is set in the register STYL, and in step S28, the mute processing of the accompaniment channel that has been sounded by the sound source 10 is performed, and in step S29, the display of the display device 3 is turned on. Then, the flag SW is reset to "0" in step S201, and the process proceeds to step S202.

In step S202, a chord corresponding to the accompaniment style number STYL and the current timing is read from the chord sequence memory, and in step S203, the accompaniment data of the accompaniment style number STYL in the accompaniment data memory is sounded according to the current timing. The data is read and output to the sound source 10, and the process proceeds to step S204. The pronunciation data is subjected to pitch conversion according to a chord other than the rhythm sound.

Next, in step S204, the counter CL
K is incremented, and CLK is 2 in step S205.
It is determined whether or not the number of clocks for a bar has been reached. If the number of clocks for a bar has not been reached, the routine returns to the original routine. When CLK reaches the number of clocks for two bars, the counter C is reached in step S206.
LK is reset to "0" to return to the original routine.

By the above processing, the display of the accompaniment style number, its display mode and the automatic performance are as shown in FIG. For example, when the automatic performance of the accompaniment style number "01" is performed at first, the display of "01" is lit on the display unit 3, and the accompaniment style number "02" is changed / instructed between the measures. At that time, the display unit 3 displays “0
The display of "2" blinks and the automatic performance of the accompaniment style number "01" continues.

When the timing of the automatic performance reaches the beginning of the next bar, the automatic performance of the accompaniment style number "02" is switched and the display of "02" on the display 3 changes from blinking to lit state.

Therefore, the performer sets "0" in the waiting state Δt after the instruction to change the accompaniment style number "02".
By the blinking display of "2", it means that it is currently in the standby state, and the current automatic performance is not the accompaniment style number "02" but the automatic performance of the previously specified accompaniment style number is continued. It can be easily confirmed.

In the above embodiment, the accompaniment style of the accompaniment is changed at the timing of the next bar after the accompaniment style change instruction is issued, but it may be changed at the beat position. It goes without saying that it is good.

In the above embodiments, lighting and blinking are used as different display modes on the display 3, but the display modes may be changed by changing the color of the LED.
Further, although the difference in the performance pattern of the automatic performance is identified by the accompaniment style number, the pattern name of the performance pattern may be displayed.

Furthermore, in the above embodiment, the present invention is applied to a plurality of performance patterns corresponding to the accompaniment style of the music, but the present invention is not limited to this, and, for example, normal performance in automatic performance, When switching between performance patterns such as fill-in performance, intro performance, and ending performance, display switching control may be performed as in the above-described embodiment.

[0056]

As described above, according to the present invention, when a new performance pattern is designated during the automatic performance, the automatic performance start by the designated performance pattern is delayed until the beat position or the bar start. In the automatic performance device configured as described above, the identification information of the currently specified performance pattern is first
The display mode is displayed on the display means in the above display mode, and the display mode while the start of the performance by the new performance pattern is delayed is made different from the first display mode. Even if the pattern corresponding to the stored identification information does not match, it is possible to immediately confirm that it is in the standby state, which improves usability in changing the performance pattern during automatic performance.
