DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic performance apparatus for recording and reproducing automatic performance data corresponding to a plurality of musical instruments.

[0002]

2. Description of the Related Art Conventionally, there has been proposed an automatic performance apparatus for storing and reproducing automatic performance data corresponding to a plurality of musical instruments in a memory.

There are the following two methods for storing automatic performance data in such automatic performance devices. One way is
This is a method of storing all the automatic performance data corresponding to a plurality of musical instruments in one track, and the other is a method of storing the automatic performance data corresponding to each musical instrument in separate tracks.

Various formats have been proposed for the format of stored automatic performance data. For example, the automatic performance data consists event data and duration data, event data is other data control change or the like indicating information on event data and operator. Duration data represents a time interval between event data. The on-event data is composed of note-on meaning a sounding instruction, data indicating the pitch of the input musical instrument (for example, note number), and velocity data indicating the intensity of the sound. The event data and the duration data are stored alternately. However, when various event data have the same generation timing, the event data may be stored continuously.

Therefore, in the method of storing the automatic performance data, in the former method, when there is a plurality of on-event data having the same output timing and different types of musical instruments, one on-event data is stored in the plurality of on-event data. One duration data is stored. On the other hand, in the latter method, even if there are a plurality of on-event data having the same output timing and different types of musical instruments, one piece of duration data (the same value) is provided for each on-event data for each track. It is memorized.

Hereinafter, the control processing of the automatic performance device configured as described above will be described with reference to the flowcharts of FIGS.

FIG. 8 is a flowchart showing the processing procedure of the main routine.

First, various initial settings such as the CPU 4 and the RAM 6 are performed (step S1).

Next, a setting processing subroutine for setting an automatic performance pattern is executed (step S2), and the LC
A display processing subroutine for displaying on the D display 3 is executed (step S3), an automatic performance processing subroutine for performing an automatic performance based on the set pattern is executed (step S4), and the copy for copying the combination pattern to the user pattern After executing a processing subroutine (step S5) and executing other processing (step S6), the process returns to step S2, and returns to steps S2 to S2.
Step S6 is repeated.

FIG. 9 is a flowchart showing a detailed procedure of the setting processing subroutine of step S2 in FIG.

First, a pattern selection process is performed in accordance with the designated pattern among the patterns 1 to 100 (step S11), and the selected pattern is displayed on the LCD display 3.
Will be displayed.

Next, it is determined whether the selected pattern is a combination pattern (step S12).
When it is a combination pattern, that is, pattern 9
When it is 0 to 100, the pattern selection processing for each musical instrument is performed as described with reference to FIG. 5 (step S13). On the other hand, when it is not a combination pattern, step S13 is skipped and the process proceeds to step S14.

In step S14, a measure to be displayed is selected in accordance with the instruction of the operator. Next, when the assignment of the pad switch is changed, the pad assignment table corresponding to the changed assignment state is selected. Is selected (step S15), and if there is an instrument pattern for which mute is instructed, mute setting processing is performed accordingly (step S15).
16), a tempo setting process for setting a tempo is performed (step S17), and other processes are performed (step S1).
8) Thereafter, the present subroutine process ends.

FIG. 10 is a flowchart showing a detailed procedure of the display processing subroutine of step S3 in FIG.

First, the bar number to be displayed selected in step S14 is read (step S21).

Next, from the pad assignment table selected in step S15, a search is made to find which pad switch the tone of each of the hi-hat HH, the bass drum BD, the snare drum SD, and other Others is assigned to. The numbers of the pad switches are designated by R
AM6 area HHPN, BDPN, SDPN, OTHP
N. Specifically, in FIG. 7 described above, for example, when obtaining the number HHPN of the pad switch corresponding to the hi-hat HH, the hi-hat tone number table is compared with the selected pad assignment table, and the numbers 10-12 are assigned. Is searched for and stored in the area HHPN. Similarly,
The tone number table corresponding to each instrument is compared with the pad assignment table, and a pad number is searched for to determine the area B
The values of DPN, SDPN and OTHPN are determined.

Next, the pat numbers HHPN, BDPN, SDPN, OT stored in step S22 are selected from the bars to be displayed of the pattern selected for each musical instrument.
After searching for the pad number corresponding to the HPN and displaying the event (step S23), the subroutine processing is terminated. That is, since the value of the number HHPN is “7” in FIG.
In addition to searching for a code having "7" and a code having a status "D" between the code having "C7" and its duration data, the timing data is obtained as shown in FIG. If there are a plurality of duration data between "C7" and "C7", the result of adding the duration data is displayed. Hereinafter, similarly, the snare drum SD and the bass drum BD are displayed. , And other corresponding patterns are displayed.

FIG. 11 is a flowchart showing a detailed procedure of the automatic performance processing subroutine of step S4 in FIG.

Firstly, the start switch 25 _1, it is determined whether or not pressed (step S31) for instructing the start of the automatic performance process of FIG 2, when pressed performs reproduction processing subroutine to be described later (step S32) On the other hand, when the button is not pressed, the process skips step S32 and proceeds to step S33.

In Step S33, it is determined whether or not the stop switch 25 ₂ for instructing termination of the automatic performance process of FIG 2 is pressed (step S33), when pressed to disable interrupts processing to be described later interrupt After the prohibition process is instructed (step S34), the present subroutine process is terminated. On the other hand, if the stop switch is not pressed, step S34 is skipped and the present subroutine process is terminated.

FIG. 12 is a flowchart showing a detailed procedure of the reproduction processing subroutine of step S32 in FIG. In this subroutine, only the initial setting of the reproduction process is performed, and the subsequent process is performed by an interrupt process described later.

First, an interrupt is permitted (step S4).
1) An interrupt process described later is performed.

Next, the value of the counter i secured in the RAM 6 (hereinafter, also referred to as "instrument i") is set to "1" (step S42). Here, the counter i takes an integer value of 1 to 4, and the integer values 1 to 4 respectively represent the hi-hat HH, the snare drum SD, the bass drum BD, and other ots.
Corresponds to hers.

Next, the head address of the pattern data corresponding to the musical instrument i is searched to obtain its address value (step S43), and the obtained address value is secured in the RAM 6 for each musical instrument. The data (code) stored in the position designated by the pointer ptr_i is read (step S45).

The data read in step S45 is
It is determined whether or not the data is the status "D" duration data (step S46). If it is the duration data, the duration data is stored in a counter count_i secured in the RAM 6 to count down the duration data (step S47). ),
It is determined whether the data determination has been completed for all the musical instruments i (step S48). At this time, if the processing has not been completed, the counter i is incremented by "1" (step S49), and the process returns to the step S43 to perform the same processing for the next instrument i + 1. When the determination is completed, the present subroutine process is completed.

On the other hand, if it is determined in step S46 that the data is not duration data, the pad number of the code is compared with the pad number corresponding to the musical instrument i (step S46).
50), it is determined whether or not they match (step S5)
1). At this time, if they do not match, the pointer ptr_
After moving i so that the next data is designated (step S52), the process returns to step S45, and the data is read at that position. On the other hand, if they match, it is determined whether or not a mute instruction has been given (step S53). If no mute instruction has been given, a sound generation process is performed (step S54), while no mute instruction has been given. In some cases, the process skips step S54 and proceeds to step S55.

In step S55, it is determined whether or not a copy instruction has been issued. If a copy instruction has been issued, the ON event is stored (step S5).
6) On the other hand, when the copy instruction has not been issued, the process proceeds to step S52, and the pointer ptr_i is advanced to the next read position. Here, copying means a process of copying the automatic performance data of the original pattern to a predetermined area (user area) of the RAM 6 in order to edit the automatic performance data of the combination pattern. That is, if the pattern of the original automatic performance data, which is a component of the combination pattern, is directly edited, the tone of the combination pattern that is not desired to be changed is changed when the pattern is used in another combination pattern. This is because there is a fear.

FIG. 13 is a flowchart showing a detailed procedure of the copy processing subroutine of step S5 in FIG.

First, it is determined whether or not there is an instruction to copy the combination pattern to the user pattern (step S61), and if so, the user area to be written is cleared (step S62), and the duration data for writing is written. The register R_dur of the RAM 6 is cleared (step S63), and after executing the above-described reproduction processing subroutine of FIG. 12 (step S64), the subroutine processing is terminated. On the other hand, if it is determined in step S61 that there is no copy instruction, steps S62 to S64 are skipped, and the present subroutine process ends.

FIGS. 14 and 15 are flowcharts showing the detailed procedure of the interrupt processing.

In the present embodiment, the timer interrupt request is sent by a timer (not shown) to 1/96 of the length of one bar,
That is, it is configured to be performed once every 96 minutes. That is, when the timer measures the time corresponding to the 96-minute length, the timer outputs an interrupt request to the CPU 4,
In response to the interrupt request, the PU 4 shifts the processing from the main routine to the timer interrupt routine. This 9
Since the time corresponding to the length of six minutes changes according to the change in tempo, the time interval at which an interrupt request is made changes according to the tempo.

First, the register R_dur is incremented by "1" (step S71), and the value of the counter i is set to "1" (step S72).

Next, the counter count_i is decremented by "1" (step S73), and it is determined whether or not the value of the counter count_i is "0" (step S74). In this determination, the counter count
When the value of _i is not "0", that is, when it is not yet the on-event sounding timing, it is determined whether or not the value of the counter i is "4", that is, whether or not the determination for all instruments has been completed. If there is still a musical instrument to be determined (step S75), the counter i is incremented by "1" (step S76), and the process returns to step S73 to move to the next musical instrument determination. On the other hand, when it is determined in step S75 that the determination has been completed for all the musical instruments, the interrupt processing ends.

On the other hand, when it is determined in step S74 that the value of the counter count_i is "0", that is, when it is the sounding timing of the ON event, the pointer ptr_i is moved to the position of the next read data.
The data is read (step S77), and it is determined whether or not the data is duration data (step S7).
8) If the data is duration data, the duration data is stored in the counter count_i (step S79), and the flow shifts to step S75.

On the other hand, if it is determined in step S78 that the data is not duration data, it is determined whether or not the data is data indicating the end of the file ("F200") (step S80 in FIG. 15). The pad number corresponding to the musical instrument i is compared with the process described in step S50 of FIG. 12 (step S81), and when they match, the same mute process as in steps S53 and S54 is performed (step S81). Steps S83 and S84).

Next, it is determined whether or not a copy instruction has been issued (step S85). If a copy instruction has been issued, the value of the register R_dur and the event data counted in step S73 are sequentially transferred to the user. Stored in the area (step S86), the register R_d
After resetting the value of ur (step S87) , the process returns to step S77 to shift the processing to the next data. When the process proceeds to step S86, the register R_d
The value of ur may be “0”. That is, there is a case where there are a plurality of event data having the same output timing. In this case, only the event data is stored in the process of step S86, and the value of the register R_dur is not stored.

In this embodiment, since the copy processing is performed during the reproduction processing of the automatic performance data, during the copy processing, the sound is generated together with the copying of the automatic performance data to the user area.

On the other hand, if there is no pad number corresponding to the musical instrument i in the determination in step S82, or if no copy instruction is given in the determination in S85, the process returns to step S77 without doing anything.

On the other hand, if it is determined in step S80 that the read data is data indicating the end of the file, it is determined whether the file is data indicating the end of the file having the longest pattern (step S8).
8) If the data is not the data indicating the end of the longest pattern file, the pointer ptr_i is moved to the head of the file, the data stored at that position is read out again (step S89), and the process returns to step S78.

Here, in the case of a combination pattern, the pattern file length of each musical instrument is often different, so that both the reproduction processing and the copy processing are performed by matching the processing to the longest pattern. When the end of the file is read, the process returns to the beginning of the file and the processing is continued.

On the other hand, when the end of the longest pattern file is detected in step S88, it is determined whether or not a copy instruction has been issued (step S9).
0), if a copy instruction has been issued, the copy instruction is released (step S91), interrupts are prohibited (step S92), and the interrupt processing ends. On the other hand, if it is determined in step S90 that a copy instruction has not been issued, the process proceeds to step S42 in FIG. 12 described above, and the process returns to the beginning of the combination pattern to continue.

As described above, in this embodiment, the pattern data of each musical instrument is recorded mixedly on one track, and the pattern data is displayed separately for each musical instrument from among them, so that the memory capacity is reduced and By improving the visibility of the pattern for each instrument, the operability of editing work and the like is improved.

In the combination pattern, the pattern corresponding to each musical instrument is stored by the pattern numbers of the preset pattern and the user pattern.
As the memory capacity is reduced, a desired pattern can be created with a simple operation.

Further, in the present embodiment, the track is not changed and recorded for each musical instrument, so that when the on-events of a plurality of musical instruments are inputted at the same time, it is sufficient to store the information as it is on a predetermined track. Becomes easier.

In the present embodiment, the present invention is applied to an electronic drum musical instrument, but is not limited to this, and may be any electronic musical instrument such as an electronic keyboard musical instrument.
