Description

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 one for controlling processing contents 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 such a musical information processing, for example, a device for changing tempo information as an example, an increment key and 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, tone color and the like is switched and displayed, and the above-mentioned increment key or decrement key is operated to change the above-mentioned tempo information and the like. In some cases, a rotary type knob is provided instead of the increment key and the decrement key, and the tempo information is changed by rotating the knob to the left and right.

On the other hand, it is considered that a reset key or the like is further provided to add a function of resetting the tempo value to a preset value. In this case, it is convenient that the tempo value is reset at the same time when the reset key is operated and 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, the current set tempo value can be confirmed by operating the display mode switching key. However, during the performance, it is difficult to operate the display mode switching key many times until the displayed contents are sequentially switched and the tempo value is displayed.

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

The present invention has been made in order to solve the above-mentioned problems, and a music capable of giving a plurality of different instructions by one operating means without providing an operating means for mode switching or function switching. The purpose is to provide a dynamic information processing device.

[0007]

In order to achieve the above-mentioned object, the present invention compares the count time from the second operation time of the operation means with the count time from the first operation time to obtain the music information. The processing contents are switched.

[0008]

With this, the instruction corresponding to the second operation is
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.

[Example] 1. Overall Circuit FIG. 1 shows the overall circuit of an electronic musical instrument. Each key of the keyboard 1 is scanned by the key scan circuit 2 to detect data indicating key-on and key-off, and C
It is written in the RAM 6 by the PU 5. Then, the CPU 5 compares the data, which has been stored in the RAM 6 up to now, with the ON / OFF state of each key, and the CPU 5 determines the ON event and the OFF event of each key. The keyboard 1 is an electronic stringed instrument or electronic wind instrument (wind).
A musical instrument, an electronic percussion instrument (such as a pad), or a computer keyboard may be used instead.

Each key of the panel switch group 3 is scanned by the panel scan circuit 4. By this scan, data indicating ON / OFF of each key or data indicating the operation amount is detected, and the CPU 5 causes the RAM 6 to operate.
Written in. Then, it is compared with the data indicating the on / off state of each key stored in the RAM 6 until then, and the on / off event of each key is discriminated by C
It 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 the tempo value on the LCD 10 and resetting the tempo value to the 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 to the reset key 13
Turn on.

The above-mentioned data and various processing data stored in the RAM 6 are displayed on the LCD (liquid crystal display device) 10 through the LCD driver 11. This R
The AM6 also stores 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 the currently set tempo value. This current tempo data PT
Is set 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 copied or may be preset by the operator. When the current tempo data PT is changed, the current tempo data PT before the change is used. May be

The on-flag data OF is set when the reset key 13 is turned on for the first time and is cleared when the reset key 13 is turned on for the second time, indicating how many times the reset key 13 is turned on. The post-operation time data OT indicates the count time after 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 is constant. If it is out of the range, only the current tempo data PT is displayed. The display time data DT indicates the time at which the tempo data PT is currently 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 on-display flag data DF is set while the current tempo data PT is being displayed.

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

The timer 12 is composed of, for example, a programmable timer or the like, data to which the tempo value information is set is set, and for example, 1/48 at a cycle corresponding to the tempo value.
The interrupt signal INT is given to the CPU 5 in the beat cycle, and the processing of the musical 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 every period of a fixed time instead of the period corresponding to the tempo. The count of the post-operation time data OT may be based on the system clock signal of the electronic musical instrument.

The tone generator 8 generates musical tone data corresponding to musical tone information such as key numbers, touches, tone colors 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
A 6-channel tone generation system is formed by time-division processing, and tone can be polyphonically generated. The musical 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 sounded.

2. Overall Process (Tempo Process) FIG. 2 shows a flowchart of the overall process 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 post-operation time data OT of M6 is "7Fн (11 ... 1)".
It also resets to.

Next, key processing (step 02) is performed.
This key processing is processing according to key-on or key-off by scanning the keys of the keyboard 1 to determine whether the keys are on or off. Then, the panel switch scanning 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 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
The post-operation time data OT is cleared to "00н (00 ... 0)" (step 08), the current tempo data PT in the RAM 6 is read out, set in the LCD driver 11, and the current tempo data PT is displayed on the LCD 10. The display flag data DF of the RAM 6 is set to "1" (step 09), and the display time data DT is cleared (steps 17 and 18). In this way, the reset key 13
The tempo value is displayed by the first operation of.

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

FIG. 3 shows the interrupt processing of the CPU 5. This process is performed every time the timer 12 supplies the interrupt signal INT to the CPU 5. In this processing, the CPU 5 causes the ON flag data O in the RAM 6 to
If F is "1" (step 21), the post-operation time data OT is incremented by 1 (step 22). Thus, after the first operation of the reset key 13, the post-operation time data O
T is incremented and the reset key 13 is 1
The time from the time of the second operation is counted.

Next, the CPU 5 determines that the display flag data DF in the RAM 6 is "1" (step 23),
The display time data DT is incremented by 1 (step 24), and 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 the above step 09 is cleared ( At step 26), the display of the current tempo data PT is discontinued and the display flag data DF and the display time data DT are cleared (steps 27 and 28). Note that this step 23
28, steps 17 and 18 may be omitted, and the display of the tempo value may be continued.

Returning to the explanation of FIG. When the reset key 13 is turned on again after the tempo value is displayed when the reset key 13 is turned on for the first time, the on flag data OF is set to "1" this time. Then, the on-flag data OF is cleared to "0" and it is determined whether or not the after-operation time data OT is within a certain range (step 14). In this fixed range, the lower limit is 0Tmin and the upper limit is 0Tmax. 0Tmin has a value of "00н" to "7Fн", and 0Tmax has a value of "7Fн" or more.

If within the range of 0Tmin to 0Tmax, the post-operation time data OT is initialized to "7Fн" (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 immediately performed continuously, and the reset key 13 is operated for a certain period of time from the first operation.
If it is within Tmin to 0Tmax, the tempo value is reset, and it is possible to switch between the first instruction content and the second instruction content of the reset key 13.

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

Post-operation time data OT in step 14 above
The same function as described above can be realized by determining whether or not is within a certain time 0Tmin to 0Tmax, even if it is only 0Tmax or less. The determination of 0 Tmin or more is also added in order to prevent an error in which the operation is actually performed only once when the reset key 13 is turned on due to a finger slip, chattering, or the like, but the operation is performed twice. is there. Of course, the determination in step 14 is 0Tmax.
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-mentioned embodiments, and various modifications can be made without departing from the spirit of the present invention. For example, the determination of the reset key 13 in step 05 of FIG.
It may be a reset key or setting knob for volume, transposition amount, type of beat, type of tone color, type of rhythm, size of effect and the like. As a result, in step 09, display processing of data such as volume and transposition amount is performed.
In 6, reset processing or change processing of data such as volume and transposition amount is performed.

The processing of step 09 may be display processing such as sound generation processing, printing processing, writing processing, reading processing, etc., and the processing of step 16 includes reset processing, change processing, and arithmetic processing. , Transfer processing, writing processing, and reading processing.

Further, the LCD 10 may be a CRT, a plasma display or the like, and the display content may be digital display such as numerical display or analog display such as 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.
