DETAILED DESCRIPTION OF THE INVENTION [Industrial applications]

The present invention relates to a parameter setting device for editing and setting parameters of an electronic musical instrument.

[Prior art]

Conventionally, a device disclosed in Japanese Patent Publication No. 1-30159 has been known as this type of device. In this device, in an electronic musical instrument having a plurality of tone generation sequences, parameters common to each tone generation sequence are integrally set by a common operator.

[Problems to be solved by the invention]

In the above-described conventional apparatus, since the tone generation sequence is fixed, if the parameter to be set integrally does not match the prepared sequence, it cannot be set integrally with a common operator. . An object of the present invention is to provide a parameter setting device capable of designating arbitrary parameters as a group and editing and setting parameters integrally for parameters designated as the same group in order to address the above problem. And

SUMMARY OF THE INVENTION

In order to achieve the above object, a structural feature of the present invention is that a parameter setting device in a tone signal generating device that generates a tone signal controlled by a plurality of parameters stores respective values of the plurality of parameters. Storage means, display means for grouping the plurality of parameters into a plurality of sets, and displaying a plurality of parameters of each group in the group in a matrix shape by a plurality of rows and columns, and a plurality of the plurality of parameters displayed by the display means. Designating means for arbitrarily designating one or more parameters from among the parameters as a group of parameters to be edited, and instructing to change each value of the plurality of parameters designated as a group of parameters to be edited by the specifying means The parameter change instruction means and the storage means are stored in the storage means for each change instruction by the parameter change instruction means. Parameter changing means for changing the values of the plurality of parameters designated as the group of parameters to be edited by the designation means collectively by different change widths respectively set for the respective parameters. It is in. According to this, in a state in which the display means displays a plurality of grouped parameters in a grid shape by a plurality of rows and columns,
One or more parameters among the plurality of displayed parameters are designated as a group of parameters to be edited by the designation means, and a plurality of parameters designated as the group of parameters to be edited are designated by the parameter change instructing means. If the change of each value is instructed, each value of the plurality of parameters stored in the storage means and designated as the group of editing parameters is changed collectively by a different change width set for each parameter. Is done. Therefore, the performer can easily specify a plurality of parameters to be changed collectively,
Since the plurality of parameters specified in the same manner can be changed collectively by different change widths set for each of the parameters, it becomes easy to set parameters for controlling the tone signal. Another structural feature of the present invention is that different change widths set for each of the above parameters are determined according to a settable range of each of the parameters. According to this, each parameter is changed by an appropriate amount for each parameter. Another feature of the configuration of the present invention is that the parameter changing unit includes a limiting unit that limits each value of the plurality of changed parameters to a predetermined range. According to this, even if a plurality of parameters are changed at the same time, each parameter does not deviate from a predetermined range. Note that a large number of musical tone generation sequences have been prepared in recent electronic musical instruments, and it is possible to play many musical instruments with one electronic musical instrument. In such an electronic musical instrument, it is convenient to group several musical tone generation sequences into one group and make various settings in accordance with the musical composition of the actual orchestra. According to the present invention, in such a case, an arbitrary parameter can be edited and set as one group, so that the effect is large even in such a use.

【Example】

Hereinafter, embodiments of the present invention will be described with reference to the drawings. First
FIG. 1 shows the overall schematic configuration of an electronic musical instrument provided with a parameter setting device according to the present invention, and FIG. 2 schematically shows the external appearance of the electronic musical instrument. In this electronic musical instrument, generation of musical tones is controlled under the control of a control unit 20 connected to the bus 10. The control unit 20 is a CPU 21
The CPU 21 executes a program stored in the ROM 22, and uses the RAM 23 for storing and reading various state variables and each variable required at that time. A keyboard 30, an operation panel 40, and a mouse 50 are connected to the bus 10, and the control unit 20 detects operation states of the keyboard 30, the operation panel 40, and the mouse 50 via the bus 10. In response to operations on the keyboard 30 and the operation panel 40, the CPU 21 transmits a key code signal KC indicating a key pressed on the keyboard 30 or a key-on signal KON indicating a key pressed state, or the operation panel 4
The tone generator circuit 60 is controlled by outputting a tone color signal representing the tone color selection at 0 to the tone generator circuit 60, thereby generating a tone signal according to the operating condition. This makes the sound source circuit 60
A tone corresponding to the tone signal is generated from a speaker 80 through a sound system 70 including an amplifier and the like. Further, the operation of the mode change switch 41 and the edit end switch 42 on the operation panel 40 and the operation of the mouse 50 correspond to the parameter edit setting, and the CPU 21 detects the operation and controls the display on the display 90, and performs the same operation. Various parameters stored in the RAM 23 are set correspondingly. The mode changeover switch 41 selects an editing mode provided in the electronic musical instrument. Each time the mode is operated, the mode changes from “0” → “1” → “2” → “3” → “0”. In the mode "0", the non-editing state of the parameter is displayed.
Modes “1” to “3” indicate the parameter editing state. The modes indicating the editing state are classified into a plurality of "1" to "3" because all parameters cannot be displayed at once on the display on the display 90. Note that the number of parameters displayed on the display 90 is up to 64 (= 8 × 8) per screen.
A maximum of 192 (= 3 × 64) parameters can be set corresponding to “3”. A group flag (GF) area (64.times.3 = 192 bits) corresponding to the display on the display 90 and indicating presence or absence of grouping designation for each parameter shown in FIG. (REG) area (64 × 3 = 192) for storing the value of each parameter shown in FIG.
Byte) are prepared. The edit end switch 42 is used to end editing after performing editing in modes "1" to "3".
In any of the modes “1” to “3”, the editing is terminated and the mode returns to the mode “0”. The mouse 50 is an operator for indicating a position on the screen of the display 90 and for giving a designated instruction to the designated object. The mouse 50 has three buttons 51, 52 and 53 for giving the instruction. ing. The middle button 51 is provided at the center of the upper surface of the mouse 50, and indicates whether or not to designate the parameters specified on the screen to a group of groups. Invert. The right button 52 is provided on the right side of the mouse, and the left button 53 is provided on the left side of the mouse.When the right button 52 is clicked, a plurality of parameters specified in a group are simultaneously specified. The value is increased by a value, and when the left button 53 is clicked, the parameter is simultaneously decreased by a predetermined value. An arrow pointing diagonally upward to the left is displayed on the screen of the display 90, and the arrow moves within the screen as the mouse 50 moves. FIG. 3 shows the display 90 in the mode "1".
This screen shows a screen for setting envelope parameters for each sounding channel.
The screen display of the display 90 is thus divided into nine columns vertically and horizontally, and a number indicating the mode is displayed in the upper left column,
Eight item names (AR, D1R, D
2R, RR, AL, D1L, D2L, DL) are displayed, the number indicating the sounding channel is displayed in the top row, and the parameters for the eight channels are displayed in the remaining 8 × 8 squares. Next, the operation of the present embodiment configured as described above will be described. When the player turns on a power switch (not shown), the CP
U21 detects the performance operation status on the keyboard 30 based on the program stored in the ROM 22, and starts control of musical tone generation according to the set parameters and the performance operation. The performer first edits and sets parameters for performance,
The performance will then begin. For editing performance parameters, an envelope of eight channels is set. The attack rate of channel 8 is the first decay rate of channels 1, 3, 4, and 6, and the attack rate of channels 2, 4, and 7. It is assumed that the second decay rate is edited and set integrally as a group of parameters. When the power switch is turned on, the CPU 21 starts execution of the main routine shown in FIG. 7, and performs initial settings such as clearing each state variable and each variable in step 102. This initial setting only needs to be performed once at first, and then the CPU 21 detects the operation status of the operation panel 40 in step 104 (hereinafter referred to as panel scan), and step 106.
The presence or absence of an operation is determined by the presence or absence of an operation event. To set the parameters, operate the mode changeover switch 41 on the operation panel 40 to set the mode “1” to “3”.
To be one of A variable MODE representing the current mode is prepared corresponding to the modes "0" to "3", and when the power is turned on, the MODE is set to "0" by the above initial setting. When the player operates the mode changeover switch 41 to display the envelope editing screen, the CPU 21 proceeds to step 104.
The same operation is detected by the panel scan in, and it is determined in step 106 that there is an event. If it is determined that there is an event, it is first determined in step 108 whether or not the mode switch 41 has been operated. Since the player has operated the mode changeover switch 41, "YES" is determined in the step 108, and in a step 110, it is determined whether or not the variable MODE representing the current mode is "0". Since the mode “0” is not the edit mode, the mouse interrupt is prohibited. However, when the mode switch 41 is operated from the mode “0”, the mode should be “1”. In step 112, mouse interruption is permitted in order to permit editing by 50. Further, in step 114, a variable M representing the mode is set.
ODE is increased by “1”, and the same variable MO
Judge whether DE exceeds the upper limit “3”. Immediately after the power supply is started, the mode is changed from “0” to “1” and the determination is “NO”. However, when the mode change switch 41 is further operated and the switch 41 is operated when the mode is changed to “3” MODE exceeds “3” and the judgment in step 116 is “Y”
ES ", and the variable MODE is set to" 0 "at step 118. Thereafter, in step 120, the display on the display 90 is rewritten according to the value of the variable MODE. In the mode "1", a screen for setting envelope parameters is displayed as shown in FIG. After the screen for editing the envelope of mode "1" is displayed,
When the mouse 50 is operated to indicate a predetermined parameter to be treated as a group, the mouse 50 generates an interrupt signal to the CPU 21. All operations of the mouse 50 are processed in the interrupt processing shown in FIG. 8, and the CPU 21 receives the same interrupt signal and proceeds to step 202.
The mouse interruption is prohibited to prevent nesting of the interruption processing, and it is determined in step 204 whether the interruption is caused by the movement of the mouse 50. If the mouse 50 has been moved, the determination is “YES”.
In step 206, the CPU 21 moves the position of the arrow on the screen, and calculates the coordinates (X, Y) indicated by the position of the arrow in step 208. This completes the mouse moving process, so that the mouse interrupt is permitted again in step 210, the interrupt process ends, and the process returns to the main routine. The player operates the mouse 50 to move the arrow on the display 90 to the square of the parameter to be edited and set,
Click the middle button 51. When the middle button 51 is clicked, an interrupt signal is transmitted from the mouse 50 to the CPU 21, and the CPU 21 executes a mouse interrupt process of step 200 and subsequent steps. Even in the interrupt processing by the middle button 51, the mouse interrupt is firstly inhibited in step 202 to prevent the nesting of the interrupt, and in steps 204 and 21
At 2,220,238, the type of operation is determined. When the middle button 51 is clicked, the determination in step 212 becomes “YES”, and in step 214 the operation is performed by operating the middle button 51 based on the coordinates (X, Y) of the arrow position on the display 90 and the variable MODE representing the mode. Identified parameters and step
At 216, the grouping designation flag GF of the same parameter is inverted. Each parameter corresponds to a state variable flag GF in an array corresponding to the order displayed on the display 90, and each flag GF can be referred to using the same order (0 to 191) as an argument. Accordingly, the same order is in the range of “0 to 63” from the upper left cell to the lower right cell on the display 90 in mode “1”, in the range of “64 to 127” in mode “2”, and in the mode “3”. In the range "128 to 191". Therefore, in step 216, the range is specified based on the mode, and the argument NUM of the flag is specified from the order of the parameters in the range by the coordinates of the arrow corresponding to the movement of the mouse 50. Inverts the value of the flag GF (NUM) corresponding to the argument. In the flag GF, “0” indicates a non-grouping designation state, and “1” indicates a grouping designation state.
By inverting the value of, the grouping designation state of each parameter is "non-designated" in response to clicking the middle button 51
The state and the "designated" state are alternately inverted. After inverting the value of the flag, the display of the display 90 is rewritten in step 218. In the present embodiment, reverse display is performed for parameters designated to be grouped, and whether the display is reverse display or normal display is determined based on the state of the flag GF. When some parameters are grouped in this way, a plurality of grouped parameters are highlighted on the display 90 as shown in FIG. In this state, the player can increase or decrease the highlighted parameters integrally, and the player can
Clicking the right button 52 of 50 increases the parameter value, and clicking the left button 53 decreases the parameter value. When the right button 52 is clicked, an interrupt signal is sent from the mouse 50 to the CPU 21, the mouse interrupt is prohibited in step 202, the operation of the mouse 50 is determined in steps 204, 212, 220, and 238, and the right It is determined that the button 52 is clicked, and the processing of steps 222 to 236 is executed. In the same processing, in order to increase the value of the parameter designated to be grouped among the parameters currently displayed on the display 90 by “1”, a variable REG (i) that stores the parameter value using the loop variable i Is appropriately increased. That is, in step 222, an initial value is substituted for a loop variable i for sequentially referring to parameters displayed on the display 90 according to the current mode, and in step 224, a parameter corresponding to the loop variable i is set. It is determined whether the value of the flag GF (i) is “0” or “1”. If the flag GF (i) is "1", the grouping is designated, and the value of the register REG (i) corresponding to the flag is increased by "1" in step 226. When the value is increased by "1", it is determined in step 228 that the maximum value corresponding to each parameter is not exceeded. If the maximum value is exceeded, the register REG is determined in step 230.
Set the same maximum value in (i). When the check of the maximum value is completed, the display of the display 90 is rewritten in step 232, and the increased parameter value is highlighted on the display. If the value of the flag is “0” in step 224, or if the display is rewritten in step 232, step 2
In step 34, the loop variable i is increased by "1", and step 236 is executed.
It is determined whether the parameter specified by the loop variable i does not exceed the end of the parameter to be edited in the mode. If it is not the last time, the process from step 224 is repeated based on the increased loop variable i. If the last time is exceeded, the mouse interrupt process is permitted in step 210 and this interrupt process ends. Since the editing of the performance parameters has been completed as described above, the player presses the edit end switch 42. Then, the CPU 21 detects an operation event on the operation panel 40 by the panel scan in step 104, and
At 106, it is determined that there is an operation event. If it is determined in step 106 that there is an operation event, it is determined in step 108 whether the operation event is caused by the operation of the mode switch 41. Since the operation event corresponds to the operation of the edit end switch 42, the determination is "NO" in this determination. In step 128, it is determined whether the operation is the operation of the edit end switch, and the determination is "YES". If the edit end switch 42 is pressed, it is not necessary to operate the mouse 50 thereafter, so step 13
Disable mouse interrupt at 0 and set variable MO at step 132
DE is set to “0” indicating the non-editing mode. Since the mode has changed, in step 120, the display on the display 90 is rewritten, and the processing corresponding to the operation event ends. Thereafter, when the performer operates the keyboard 30 to perform,
The CPU 21 scans a switch group corresponding to each key on the keyboard 30 in step 122 to detect a performance operation on the keyboard 30, and if it is determined in step 124 that there is a key event, the CPU 21 determines that there is a key event in step 126. Performs sound processing according to the sound. That is, the CPU 21 outputs a key code signal KC representing a key depressed on the keyboard 30 and a key-on signal KON representing a depressed state to the tone generator 60, and the tone generator 60 generates a tone signal in accordance with the signal. Then, a tone corresponding to the tone signal is generated from the speaker 80 via the sound system 70. At this time, the tone generator 60 generates a register (REG (0 to 0) in the RAM 23 when forming a musical tone waveform or the like.
Since each parameter stored in (191)) is referred to, each envelope is realized as set in correspondence with the above-described editing setting operation. If the parameter needs to be edited again, the desired parameter may be edited again and again as described above. At this time, if the user wants to decrease the setting information in the specified group of parameters, the user clicks the left button 53 of the mouse 50. Then, an interrupt signal is sent from the mouse 50 to the CPU 21, and after disabling the mouse interrupt in step 202, the operation of the mouse 50 is determined in steps 204, 212, 220, and 238, and the click of the left button 53 is determined in step 238. Then, the processing of steps 240 to 254 is executed. In the same process, a variable REG (i) that stores a parameter value using a loop variable i in order to reduce the value of a parameter designated to be grouped among parameters currently displayed on the display 90 by “1”. Is appropriately reduced. That is, in step 240, an initial value is substituted for a loop variable i for sequentially referring to parameters displayed on the display 90 according to the current mode, and in step 242, a parameter corresponding to the loop variable i is set. Flag GF (i)
Is determined to be “0” or “1”. If the flag GF (i) is "1", the grouping is designated, and the value of the register REG (i) corresponding to the flag is reduced by "1" in step 244. When the value is decreased by “1”, it is determined in step 246 that the minimum value corresponding to each parameter is not exceeded. If the minimum value is exceeded, the register REG is determined in step 248.
The same minimum value is set in (i). When the check of the minimum value is completed, the display of the display 90 is rewritten in step 250, and the reduced parameter value is highlighted on the display 90. If the value of the flag is “0” in step 242, or if the display is rewritten in step 250,
In step 52, the loop variable i is increased by “1”, and step 254 is executed.
It is determined whether the parameter specified by the loop variable i does not exceed the end of the parameter to be edited in the mode. If it is not the last time, the process from step 242 is repeated based on the increased loop variable i. If the last time is exceeded, the mouse interrupt process is permitted in step 210 and this interrupt process ends. If any other switch on the operation panel 40 is operated, “NO” is determined in both steps 108 and 128, and processing corresponding to each switch is performed in step 134. In the above embodiment, a mouse is used to indicate a parameter on the display. However, a configuration in which the same instruction is performed using a cursor and a switch may be used. Further, another operation button may be provided on the mouse to simplify the grouping instruction. For example, when one of the buttons is pressed, all the parameters displayed on the display can be set to the designated state, or vice versa. Further, the value to be increased / decreased as a unit is not limited to “1” as in the above-described embodiment, and may be increased / decreased by a value of a fixed ratio according to a change range for each parameter.
For example, if the change range of the parameter A is "0" to "99",
If the change range of the parameter B is "0" to "9", the parameter A is changed by "10" with one click of the buttons 52 and 53, and the parameter B is changed by "1". Just do it. More specifically, what is added or decreased by “1” to the update of the register REG (i) in steps 236 and 218 may be set as REG (i) = REG (i) + (change range) / 10. Of course, in this case, REG (i) should be able to store a real value. Furthermore, in the above embodiment, the present invention is implemented as software. However, the present invention may be implemented as a microprogram or hardware. Any parameters that are normally present are possible. In addition, mouse processing can be realized other than interrupt processing,
It is also possible to configure the display with an external CRT.
