DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a musical information processing apparatus, and more particularly to an apparatus for controlling the processing of musical information based on a relationship between a first operation and a second operation of operating means.

[0002]

2. Description of the Related Art Conventionally, taking an example of such musical information processing, for example, a device for changing tempo information, an increment key, a decrement key and a display mode switching key are provided, and the display mode is switched by the display mode switching key. By switching, for example, information such as tempo, transposition, time signature, volume, and tone is switched and displayed on the display device, and the tempo information and the like are changed by operating the increment key or the decrement key. In some cases, a rotary knob is provided in place of the increment key and the decrement key, and the knob is turned right and left to change tempo information.

On the other hand, it has been considered that a reset key or the like is further provided to add a function of resetting a tempo value to a preset value. In this case, it is convenient that the tempo value is reset simultaneously with the operation of the reset key, and that the display mode of the display device is automatically switched to the display of tempo information. Then,
You can easily check the tempo value.

[0004]

However, such a reset key only resets the tempo value.
Although the reset tempo value is displayed, the current set tempo value cannot be confirmed. Of course, if the display mode switching key is operated, the current set tempo value can be confirmed. However, it is difficult to repeatedly switch the display contents during the performance and operate the display mode switching key many times until the tempo value is displayed.

Therefore, especially during a performance, it is very convenient to be able to instantly check the current set tempo value and to reset the tempo value by a simple operation. In this case, if these functions can be realized by one key, the number of keys can be reduced and the whole apparatus can be made compact.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and is provided with a music operation system in which a plurality of different instructions can be issued by one operation means without providing an operation means for mode switching or function switching. The purpose of the present invention is to provide a dynamic information processing device / method. This is not limited to the switching of the tempo value, and the same applies to other musical information for controlling the contents of musical tones such as the above-described transposition, beat or volume values, and timbre types.

[0007]

In order to achieve the above object, according to the present invention, a second operation is performed by comparing a count time from the first operation time with a second operation time of the operation means. If the time point is within a predetermined time range from the first operation time point, the value of the musical information is initialized by operating the operation means, and the second operation time point is within a predetermined time period from the first operation time point Otherwise, the value of the musical information is not initialized by the operation of the operation means. Also, in the present invention, the second operation time of the operating means is compared with the count time from the first operation time, and the second operation time is within a predetermined time from the first operation time. Otherwise, the value of the musical information is not changed by the operation of the operating means, but only the value of the musical information corresponding to the operating means is displayed.
If the time point of the second operation is within a predetermined time range from the time point of the first operation, the value of the musical information is changed by operating the operation means.

[0008]

According to this, the instruction corresponding to the second operation is set to 1
Switching can be performed according to the count time from the time of the second operation, and a plurality of different contents can be instructed by one operating means.

[0009]

[Examples] 1. Overall Circuit FIG. 1 shows the overall circuit of an electronic musical instrument. Each key of the keyboard 1 is scanned by a key scan circuit 2 to detect data indicating key-on and key-off,
The data is written to the RAM 6 by the PU 5. Then, the data is compared with the data indicating the on / off state of each key stored in the RAM 6 until then, and the CPU 5 determines the on / off event of each key. The keyboard 1 is an electronic stringed instrument, an electronic wind instrument (tube).
A musical instrument, an electronic percussion instrument (such as a pad), a computer keyboard, or the like may be used instead.

Each key of the panel switch group 3 is scanned by a panel scan circuit 4. By this scan, data indicating on / off of each key or data indicating an operation amount is detected, and the CPU 5 stores the data in the RAM 6.
Is written to. Then, the data is compared with the data indicating the on / off state of each key stored in the RAM 6 until then, and the discrimination between the on event and the off event of each key is determined by C
This is performed by PU5. A reset key 13 is provided in the panel switch group 3. The reset key 13 is a key for displaying a tempo value on the LCD 10 and resetting the tempo value to an initial value. To reset the tempo value to the initial value, turn on the reset key 13 to display the tempo value, and immediately continue the reset key 13
Just turn on.

The above-mentioned data and various processing data stored in the RAM 6 are displayed on an LCD (liquid crystal display) 10 through an LCD driver 11. This R
The AM 6 also stores the current tempo data PT, initial tempo data IT, on-flag data OF, post-operation time data OT, display time data DT, display flag data DF, and the like.

The current tempo data PT indicates a currently set tempo value. This current tempo data PT
Is achieved by operating the increment key 14a or the decrement key 14b. The initial tempo data IT indicates a value when the tempo value is reset by the reset key 13. The initial tempo data IT may be stored in the ROM 7 in advance, and may be copied or arbitrarily preset by the operator, or when the current tempo data PT is changed, the current tempo data PT before the change may be used. It may be.

The on-flag data OF is set when the reset key 13 is turned on for the first time, is cleared when it is turned on for the second time, and indicates the number of times the reset key 13 is turned on. The post-operation time data OT indicates a count time from when the reset key 13 is turned on. If the post-operation time data OT is within a certain range, the current tempo data PT is reset to the initial tempo data IT, and the post-operation time data OT is reset. If it is out of the range, only the current tempo data PT is displayed. The display time data DT indicates the time during which the current tempo data PT is displayed on the LCD 10. When the display time data DT reaches a certain time, for example, 3 seconds, the display of the current tempo data PT automatically ends. . The display flag data DF is set while the current tempo data PT is being displayed.

The ROM 7 stores a program corresponding to a flowchart described later by the CPU 5 and a program corresponding to other processing. Automatic performance data is stored in the ROM 7 or the RAM 6, and the automatic performance is performed.

The timer 12 is constituted by, for example, a programmable timer or the like, in which data corresponding to the above-mentioned tempo value information is set.
An interrupt signal INT is given to the CPU 5 at a beat cycle, and the processing of the tone information according to the count of the post-operation time data OT and the tempo is executed. The timer 12 may output the interrupt signal INT at intervals of a fixed time, instead of at intervals corresponding to the tempo. The count of the post-operation time data OT may be based on a system clock signal of the electronic musical instrument.

The tone generator 8 generates tone data corresponding to tone information such as key numbers, touches, timbres, and rhythms input from the keyboard 1 and the panel switch group 3 or in the automatic performance data. The tone generator 8 has a plurality of channels, for example, 1 channel.
A tone generation system for six channels is formed by time-division processing, and a tone can be generated polyphonically. The tone information assigned to each channel is stored in an assignment memory (not shown). The generated tone data is sent to the sound system 9 and is generated.

[0017] 2. Overall Processing (Tempo Processing) FIG. 2 shows a flowchart of overall processing performed by the CPU 5. This process starts when the power is turned on. In this process, the CPU 5 first performs an initialization process (step 01). In this initialization process, RA
The time data OT after the operation of M6 is "7Fн (11 ... 1)"
Also reset to.

Next, key processing (step 02) is performed.
This key processing is processing corresponding to key-on or key-off by scanning the keys of the keyboard 1 to determine whether the key is on or off. Then, a panel switch scan process is performed (step 03). In this scanning, there is an ON event (step 04), and if this ON key is the reset key 13 (step 05), RA
It is determined whether or not the ON flag data OF of M6 is "1" (step 06).

If the ON flag data OF is "0" and the reset key 13 is turned on for the first time, the ON flag data OF is set to "1" (step 07), and the RAM 6
Clears the time data OT to "00 н (00 ... 0)" (step 08), reads the current tempo data PT in the RAM 6, sets it in the LCD driver 11, and displays the current tempo data PT on the LCD 10. Then, the display flag data DF of the RAM 6 is set to "1", and the display time data DT is cleared (steps 17 and 18). Thus, the reset key 13
By the first operation, the tempo value is displayed.

If the keys other than the reset key 13 are turned on in step 05, on-event processing of the other keys is performed (step 10). Further, if there is an off event in the panel switch scan processing in step 03 (step 11), the off event processing is performed (step 12).

FIG. 3 shows the interrupt processing of the CPU 5. This process is performed every time the interrupt signal INT is supplied from the timer 12 to the CPU 5. In this process, the CPU 5 sends the ON flag data O
If F is "1" (step 21), the post-operation time data OT is incremented by 1 (step 22). Thus, the time data O after the first operation of the reset key 13
T is incremented and the reset key 13
The time from the time of the second operation is counted.

Next, if the display flag data DF in the RAM 6 is "1" (step 23),
The display time data DT is incremented by 1 (step 24). If the display time data DT matches the data for 3 seconds (step 25), the current tempo data PT set in the LCD driver 11 in step 09 is cleared (step 24). Step 26), the display of the current tempo data PT is terminated, and the display flag data DF and the display time data DT are cleared (steps 27 and 28). This step 23
To 28, steps 17 and 18 may be omitted, and the display of the tempo value may be continued.

Returning to the description of FIG. When the reset key 13 is turned on again after the tempo value is displayed by the above-mentioned first turning on of the reset key 13, the on-flag data OF is set to "1". Then, the on-flag data OF is cleared to "0", and it is determined whether or not the post-operation time data OT is within a certain range (step 14). This fixed range has a lower limit of 0 Tmin and an upper limit of 0 Tmax. 0Tmin takes a value from “00」 ”to“ 7F 」”, and 0Tmax takes a value equal to or more than “7F」 ”.

If it is within the range of 0 Tmin to 0 Tmax, the post-operation time data OT is initialized to "7F н" (step 15), and the current tempo data PT is reset to the same value as the initial tempo data IT (step 16). . Then, the tempo value display processing of step 09 is performed. In this way, the second operation of the reset key 13 is performed immediately after the first operation, and the reset operation is performed for a certain period of time after the first operation.
If it is within the range of Tmin to 0 Tmax, the tempo value is reset, and the first instruction content and the second instruction content of the reset key 13 can be switched.

If the post-operation time data OT is not within the predetermined time 0Tmin to 0Tmax in step 14, the tempo value reset processing in steps 15 and 16 is not performed, and only the tempo value display processing in step 09 is performed. . In this way, the second operation of the reset key 13 is performed with a time interval, and the reset key 13 is operated for a certain time from 0Tmin to 0Tmin after the first operation.
If it is not within Tmax, only the same tempo value display as the first operation is performed, and the first instruction content and the second instruction content of the reset key 13 are not switched.

The post-operation time data OT in step 14
Is within a certain period of time from 0 Tmin to 0 Tmax, the same function as described above can be realized even if the determination is only 0 Tmax or less. The reason why the discrimination of 0 Tmin or more is also added is to prevent an error in which, when the reset key 13 is turned on, a finger is slipped or chattering or the like is actually performed only once but is determined to be performed twice. is there. Of course, the discrimination in step 14 is made 0 Tmax.
Only the following determination or only the determination of 0 Tmin or more may be performed.

The present invention is not limited to the above embodiment, but can be variously modified without departing from the spirit of the present invention. For example, the determination of the reset key 13 in step 05 of FIG.
Reset keys or setting knobs for volume, transposition amount, time signature type, tone color type, rhythm type, effect size, etc. may be used. As a result, in step 09, display processing of data such as the volume and the amount of transposition is performed.
In step 6, a process of resetting or changing data such as the volume and the amount of transposition is performed.

The display processing in step 09 may be a sound generation processing, a printing processing, a writing processing, a reading processing, or the like. The processing in step 16 may be a reset processing, a change processing, or an arithmetic processing. , Transfer processing, write processing, and read processing.

Further, the LCD 10 may be a CRT, a plasma display or the like, and the display content may be a digital display such as a numerical display or an analog display such as a scale display. The reset key 13 may be of any type such as a button type, a key type, a lever type, and a foot switch type.
