Description

  The present invention relates to a parameter setting device for setting a parameter value of a musical tone control device, and more particularly to a parameter setting device suitable for setting a velocity curve value.

For example, in an electronic musical instrument such as a synthesizer, a parameter called “velocity curve” has been conventionally known as one of parameters for controlling the characteristics of a musical sound that is generated according to a performance operation. The velocity curve is a parameter for determining a velocity value output with respect to the strength of the performance operation of the electronic musical instrument. In a synthesizer known in the past, as a value to be set in the velocity curve, a plurality of types of options (curves) that define the correspondence between the strength of the key press and the velocity value are prepared. There is one that allows the user to select one (see, for example, Non-Patent Document 1 below).
http://www2.yamaha.co.jp/manual/pdf/emi/japan/synth/MOTIFESJ1.pdf (Electronic musical instruments released by the applicant: page 260 of the “MOTIF ES” instruction manual)

  In the synthesizer described in Non-Patent Document 1, there is an option “fix” as one of a plurality of options prepared as values to be set in the velocity curve. When an option other than “Fix” is selected, the velocity value corresponding to the key press strength is output, whereas when “Fix” is selected, the velocity value is related to the key press strength. A constant velocity value is output. The fixed value output as the velocity value when “Fix” is selected can be arbitrarily set by the user.

  In the electronic musical instrument shown in Non-Patent Document 1, the value (option) set in the velocity curve is changed on the utility screen for setting parameters common to the entire system. The user calls the utility screen on the display of the electronic musical instrument, selects a velocity curve setting item from a plurality of setting items prepared in the called utility screen, and changes the velocity curve value. . In the electronic keyboard instrument shown in Non-Patent Document 1, once the user sets a desired velocity curve value, there is little opportunity to change the velocity curve value, and the velocity curve value is changed from the utility screen as described above. Even if the configuration to be changed, that is, the configuration in which the physical switch for setting the value of the velocity curve is not provided, no particular inconvenience occurred.

  Incidentally, in an electronic musical instrument system that controls performance (musical sound generation) using an external sound source using an electronic musical instrument, a plurality of external sound sources may be controlled by a single electronic musical instrument. The plurality of external sound sources have different volume feelings, that is, even if they have the same velocity value, the sound volume produced corresponding to the velocity value differs for each sound source used. For this reason, in order to realize the music performance desired by the user in this type of system configuration, it is desirable to change the value of the velocity curve to the optimum value for the sound source in use every time the sound source to be used is switched. Therefore, in such an electronic musical instrument system configuration, the velocity curve value is changed more frequently, and not only the frequency is increased, but also the velocity curve value such as a situation where the velocity curve value is desired to be changed during performance, for example. There are many situations where you want to make changes quickly.

  Therefore, in the electronic musical instrument system that controls a plurality of external sound sources with one electronic musical instrument, if the conventional velocity curve value setting method as described in Non-Patent Document 1 is adopted, the velocity curve value is frequently set. There was an inconvenience that it took too much time and labor to change. That is, in a system configuration in which a plurality of external sound sources are controlled by one electronic musical instrument, it is desirable that the velocity curve value can be changed as easily and quickly as possible. Further, the setting items of the velocity curve include not only the setting of the velocity curve value (option) but also the setting of the velocity value (fixed value) when “fix” is selected. Therefore, it is desired that the setting of two setting items, that is, a velocity curve value and a velocity value when “fix” is selected, can be set easily and quickly.

  The present invention has been made in view of the above points. For example, a special option (fix) having an additional parameter, such as a velocity curve, and a general option (other than the fix) having no additional parameter, are available. It is an object of the present invention to provide a parameter setting device that can easily and quickly set parameter values having a plurality of options.

The parameter setting device according to the present invention is a parameter setting device that sets a value of a parameter of a musical tone control device, wherein the parameter sets any one of a plurality of options as the value of the parameter, In addition, one of the plurality of options is a special option having an additional parameter, and the rest are parameters that are general options having no additional parameter, the first operation mode or the second option. The setting operator operated in any one of the operation modes, the operation of the setting operator being operated, and the operation is either the first operation mode or the second operation mode An operation detecting means for detecting whether or not an operation of the first operation mode is detected by the operation detecting means; a current operation mode is a first operation mode and a second operation mode; When it is determined and the mode is determined to be the first operation mode, the option corresponding to the detected operation is set as the value of the parameter, and when the mode is determined to be the second operation mode. A first parameter setting means for setting a value corresponding to the detected operation as the value of the additional parameter, and when the operation of the second operation mode is detected by the operation detection means, It is determined whether the operation mode is the first operation mode or the second operation mode. When the operation mode is determined to be the first operation mode, the operation mode is switched to the second mode and the special mode is selected. When the option is set as the value of the parameter and is determined to be the second operation mode, the operation mode is switched to the first operation mode, and a specific one of the general options is set to the parameter. And a second parameter setting means for setting a value.

  According to this, by providing the first parameter setting means, the user only operates the setting operator in the first operation mode, and the detected operation is performed when the current operation mode is the first operation mode. An option corresponding to the operation can be set as the value of the parameter, and a value according to the detected operation can be set as the value of the additional parameter in the second operation mode. Further, by providing the second parameter setting means, the user only operates the setting operator in the second operation mode, and when the current operation mode is the first operation mode, the operation mode is set to the second operation mode. In addition to switching to the mode, a special option can be set as a parameter value. In the second operation mode, the operation mode is switched to the first operation mode and a specific one of the general options is selected. Can be set as the value of the parameter.

  As a preferred embodiment of the present invention, the parameter setting device includes a performance operator for performing a performance operation by a user, and a sound for detecting a pitch corresponding to the operation when the performance operation member is operated. The strength of the operation is detected when the high detection means and the performance operator are operated, and the detected operation strength is supported according to the parameter value set at the time of the operation. A velocity determining means for determining a velocity value to be performed; and a sound generation instruction output means for outputting the pitch detected by the pitch detecting means and the velocity value determined by the velocity determining means as a sound generation instruction. The parameter is a velocity curve parameter that defines the correspondence between the strength of the operation of the performance operator and the velocity value, and the value of the parameter is A plurality of types of curves are prepared as the plurality of options to be set, and the general options of the plurality of options are curves having different velocity values depending on the strength of operation, Of the plurality of options, the special option is a curve having a constant velocity value regardless of the strength of the operation, and the additional parameter is the constant value.

  Moreover, as one preferable embodiment of the present invention, the setting operation element is composed of two sets of push button switches, and the first operation mode is a set of two operation buttons. One of the push button switches is an operation mode in which the switch is operated alone, and the second operation mode is an operation mode in which both of the two push button switches are pressed simultaneously.

  According to the parameter setting device of the present invention, for a parameter having a plurality of options including a special option having an additional parameter and a general option not having the additional parameter, the setting operator can select an option. The selection can be performed easily and quickly, and an additional effect of changing the additional parameter of the special option can be easily and quickly performed using the same setting operator. For example, if the parameter setting device according to the present invention is applied to the setting of the value of the velocity curve, a setting for selecting a desired option from a plurality of options (curves) and a fixed value when a fix is selected as the option are selected. Setting of two setting items, that is, value setting, can be performed easily and quickly, and there is a remarkable effect that operability related to setting of the value of the velocity curve is improved. In addition, by using a setting operator common to the selection operation of choices and the setting operation of a fixed value at the time of selecting a fix, even if it is configured to add a new setting operator to the parameter setting device, The increase in the number of parts and cost can be minimized.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram showing an outline of the configuration of an electronic musical instrument system to which parameter values according to one embodiment of the present invention are applied. The electronic musical instrument system shown in FIG. 1 is composed of two devices: a musical tone control device 1 and a musical tone sounding device 2 externally connected to the musical tone control device 1. The musical tone control device 1 is a controller for performing musical performance operation by a user and controlling musical tone generation by the sound source 3 provided in the musical tone generating device 2 based on the musical performance operation. The musical tone control device 1 includes a keyboard unit composed of a plurality of keys, for example. Consists of a keyboard-type controller.

  The musical tone generating device 2 is a device that performs a performance (musical tone generation) with the sound source 3 based on an instruction from the musical tone control device 1, and can be configured by, for example, a general-purpose personal computer (hereinafter abbreviated as PC). The PC 2 includes a plurality of sound sources 3 (four sound sources 3 in FIG. 1), and the plurality of sound sources 3 are configured by software programs that provide a sound source function. In FIG. 1, alphabetic characters “A”, “B”, “C”, and “D” are assigned to each sound source 3 to indicate that these four sound sources are different from each other. As an implementation example of the software tone generator 3, the plurality of software tone generators 3 can be configured by plug-in software that provides a tone generator function in an application program that causes the PC 2 to realize a music sequencer function.

The musical sound control device 1 is connected to the PC 2 so as to be able to perform data communication. The musical sound control device 1 transmits sound generation instruction data corresponding to the performance operation input by the user to the PC 2, and the software sound source 3 of the PC 2 is based on the sound generation instruction data. Let the sound be pronounced. The musical sound control device 1 can control each of the four software sound sources 3 provided in the PC 2. Since the musical sound control device 1 can control only one sound source at a time, the software sound source 3 is individually controlled while switching the software sound source 3 to be controlled. The user selects one of the four software sound sources 3 provided in the PC 2 as the output destination of the sound generation instruction data, so that the sound generation instruction data output from the musical sound control device 1 to the PC 2 is sent to any sound source 3. You can set whether to enter. The output destination of the sound generation instruction data may be set using a panel operator provided in the musical tone control apparatus 1 or an operator provided in the PC 2. That is, the setting of the output destination of the sound generation instruction data may be performed from either the musical tone control device 1 or the PC 2. Since the plurality of software sound sources 3 have different volume feelings, that is, the sound volume at the time of sound generation with respect to the velocity value, each time the sound source 3 to be used is switched, the velocity curve value setting described later is also used. As described above, it is preferable to change according to the sound source 3.
According to this embodiment, as will be described in detail later, the value of the velocity curve can be changed easily and quickly. Therefore, the electronic musical instrument system having the configuration shown in FIG. In this case, the effect of the parameter setting device of the present invention is great.

  FIG. 2 is a block diagram showing an example of the electrical hardware configuration of the musical tone control apparatus 1. In FIG. 2, the musical tone control apparatus 1 includes a microcomputer including a CPU 10, a ROM 11, a RAM 12, and a timer 10 a, and includes a performance operation detection circuit 17 that detects a performance operation of the performance operator group 13 and a panel operation group 14. The setting operation detection circuit 18 for detecting an operation, an external communication interface (external communication I / F) 16 for communicating with the musical tone generating device 2, and a display circuit 19 for controlling the display of the display 15 are provided via the bus 10b. Connected to a microcomputer. That is, in this embodiment, the musical tone control apparatus 1 does not have a mechanism (sound source circuit or the like) for generating a musical tone. The CPU 10 executes a control program stored in the ROM 11 or the RAM 12, and controls the operation of each unit connected to the bus 10b. Further, the RAM 12 is provided with a buffer area used for setting a velocity curve value to be described later.

  The performance operator group 13 is a plurality of performance operators that specify the pitch of a musical tone. In the musical tone control apparatus 1 of this embodiment, the musical performance control group 13 is constituted by a keyboard having a plurality of keys. The performance operation detection circuit 17 detects the presence / absence of each operation of the performance operator group (keyboard) 13 and the pitch corresponding to the operation, and also detects the strength of the performance operation (key press strength). can do. The key depression data detected by the performance operation detection circuit 17 is used to determine the velocity value when an option other than “fix” is selected as the velocity curve value, as will be described later. .

  The panel operator group 14 is an operator group provided on the upper surface of the casing panel of the musical tone control apparatus 1 for setting various parameters, and includes a switch for setting a velocity curve according to the present invention (described later). FIG. 4). The operation state of the panel operator group 14 is detected by the setting operation detection circuit 18, and the CPU 10 performs various controls related to parameter setting based on the detection result. The display 15 is a small and simple display composed of, for example, an LCD display, and is installed on the upper surface of the casing panel of the musical tone control device 1 (see FIG. 4 described later). Based on the control of the display circuit 19, various information such as a character string explaining the setting state of various parameters is displayed on the display 15.

  The musical tone control device 1 is connected to a musical tone generating device (PC) 2 through an external communication I / F 16, and through the external communication I / F 16, sound generation instruction data (key-on data, sound High (note number data, velocity value, etc.) is transmitted to the tone generator 2. That is, as described above, one of the four software sound sources 3 provided in the PC 2 is set as the output destination of the sound generation instruction data, and the sound generation instruction data generated in response to the performance operation includes the sound generation instruction data. At the time of occurrence, it is transmitted to one sound source 3 set as the output destination. The external communication I / F 16 is conventionally known as long as it is an interface using a communication technique that can cause the musical tone sounding apparatus 2 to generate a musical sound according to an instruction from the musical sound control apparatus 1 in substantially real time. Any standard communication interface may be applied, for example, a communication I / F using a dedicated line with a high communication speed, such as a MIDI cable connection, a USB cable connection, or an IEEE 1394 cable connection. In addition to the sound generation instruction data, parameter value data of the tone control device 1 may be transmitted from the tone control device 1 to the PC 2 via the external communication I / F 16.

  FIG. 3 is a block diagram showing an example of the electrical hardware configuration of the tone generator (PC) 2. In FIG. 3, the PC 2 includes a microcomputer including a CPU 20, a ROM 21, a RAM 22 and a timer 20a, an operation detection circuit 26 for detecting the operation of the operator 23, a display circuit 27 for controlling the display of the display 24, and a musical tone control. An external communication I / F 25 for communicating with the apparatus 1 is connected to the microcomputer via the bus 20b. As described above, the PC 2 has a software sound source (see FIG. 1) configured by a software program executed by the CPU 20 as a plurality of sound sources 3 for generating a musical sound based on the sound generation instruction transmitted from the musical sound control device 1. It is equipped.

  The operation element 23 is a mouse or a keyboard that is externally connected to the main body of the PC 2. The display 24 is a display externally connected to the main body of the PC 2, and is configured by, for example, an LCD display or a CRT display. For example, even if the screen for setting the parameter value of the musical tone control device 1 is displayed on the display unit 24 of the PC 2 and the parameter value in the musical tone control device 1 can be set from the screen of the display unit 24 using the operator 23. Good.

  The PC 2 is connected to the musical tone control apparatus 1 via the external communication I / F 25 and can receive a sound generation instruction from the musical tone control apparatus 1. The external communication I / F 25 is the same as the external communication I / F 16 provided in the musical sound control device 1, and the tone generation of the musical sound according to the instruction from the musical sound control device 1 is performed in the PC 2 in substantially real time. As long as it can be performed, any conventionally known communication I / F such as a MIDI cable connection, a USB cable connection, or an IEEE 1394 cable connection may be applied. In addition to receiving the sound generation instruction, other data such as parameter value data may be communicated between the PC 2 and the musical tone control apparatus 1 via the external communication I / F 25.

  FIG. 4 is a plan view of the housing 30 of the musical sound control device 1 as viewed from the upper surface (panel surface) side. The casing 30 is provided with a keyboard (performance operator group) 13 composed of a plurality of keys, a display 15 and a panel operator group 14 for parameter setting. An external sound source controller such as the musical sound control apparatus 1 is required to reduce the number of panel operation elements 14 to be arranged as much as possible for reasons such as cost reduction.

  In the musical tone control apparatus 1 according to this embodiment, the panel operator group 14 includes dedicated push button switches 31 and 32 for setting a velocity curve value. The switches 31 and 32 for setting the value of the velocity curve are a set of two switches including an increment switch (INC) 31 and a decrement switch (DEC) 32. On the panel surface of the housing 30, in addition to the switches 31 and 32, switches dedicated to specific functions, a cursor switch for setting a parameter value displayed on the display 15, and a rotation operation are performed. Necessary minimum switches such as knob type controls and wheel type controllers are provided.

  Here, the parameters of the “velocity curve” that is the control target of the switches 31 and 32 will be described. The velocity curve is a parameter that defines the correspondence between the strength of the performance operation on the keyboard 13 (the strength of the key press detected by the performance operation detection circuit 17 (see FIG. 2)) and the velocity value. A parameter for setting one of the options as the value of the velocity curve, and at least one of the plurality of options is a “special option” having an additional parameter, and the rest are the additional parameters. It is a "general option" that does not have

  In this embodiment, the general options among the options set as the value of the velocity curve are four types of curves having different velocity values depending on the strength of the key depression. This curve has a constant velocity value regardless of the strength of key depression. In this embodiment, each of the four types of curves prepared as the general options is referred to as “curve A”, “curve B”, “curve C”, and “curve D”. The curve prepared as the special option is called “fix”.

  The four types of curve A, curve B, curve C, and curve D prepared as the general options are information defining rules for converting key-pressing strength into velocity values, respectively. The velocity value corresponding to the key-pressing strength can be configured by a data table that defines in advance. That is, the ROM 11 or RAM 12 of the musical tone control device 1 stores four types of data tables corresponding to the curves A to D, and any one of the curves A to D is set as the velocity curve value. In some cases, a velocity value corresponding to the key-pressing intensity detected by the performance operation detection circuit 17 is output based on a table corresponding to one of the selected curves A to D. The curves A to D may be configured and implemented in any form as long as the information defines a rule for converting the key depression strength into the velocity value, and is different from the data table. As a configuration example, it can be configured by a function having a key depression strength as a variable. In this case, the key depression intensity detected by the performance operation detection circuit 17 is input to a function corresponding to one of the currently selected curves A to D, and the result of calculation is the detected depression. It is output as a velocity value corresponding to the strength of the key.

  Further, when “fix” is selected as the velocity curve value, a constant velocity value arbitrarily set by the user is output regardless of the strength of the key depression. A constant value when “fix” is selected as the value of the velocity curve is the “additional parameter”. Hereinafter, the fixed value when “fix” is selected is referred to as “fix value”. The fix value can be arbitrarily set by the user. The fix value set by the user is stored in a buffer area (see FIG. 5 described later) secured in the RAM 12 of the musical tone control apparatus 1.

  As is apparent from the above, the setting items for the velocity curve include two setting items: [1] curve (option) selection and [2] fix value setting. For this reason, in this embodiment, as the operation modes of the switches 31 and 32, two operation modes of “first operation mode” and “second operation mode” described below are prepared.

  The “first operation mode” is a state in which the general option (any one of the curves A to D) is selected as the value of the velocity curve, and the switch 31 or the switch 32 is set to the velocity curve. This mode is used for setting values (options). In the first operation mode, when either the switch 31 or the switch 32 is operated, new options (curves A to D) are selected as the velocity curve value. That is, every time the user operates the increment switch 31, the selection state of the options is sequentially changed in the order of curve A, curve B, curve C, curve D, curve A,. Each time the user operates the decrement switch 32, the selection state of the options is sequentially changed in the order of curve D, curve C, curve B, curve A, curve D,. The operation of the increment switch 31 in the state where the curve D is selected and the curve A are selected, not limited to the parameter changing method in which the selection state of the options is circulated according to the operation of the switch 31 or the switch 32. A parameter changing method that disables the operation of the decrement switch 32 in the state (no change in the selected state) may be employed.

  The “second operation mode” is a state in which the special option (“fix”) is selected as the value of the velocity curve, and the switch 31 or the switch 32 is changed in the value of the fix value (additional parameter). This mode is used for In the second operation mode, when either the switch 31 or the switch 32 is operated, the fix value is changed. That is, each time the user operates the increment switch 31, the value of the fix value increases by one step, and every time the user operates the decrement switch 32, the value of the fix value decreases by one step. To do.

  Further, the operation for switching the operation mode between the “first operation mode” and the “second operation mode” can be performed by operating (simultaneously pressing) both the increment switch 31 and the decrement switch 32. . As shown in FIG. 4, the increment switch 31 and the decrement switch 32 are arranged side by side on the panel surface of the casing 30 of the musical tone control device 1 so that the user can easily perform the simultaneous pressing operation. The setting operation detection circuit 18 determines the simultaneous pressing operation of the increment switch 31 and the decrement switch 32 by, for example, holding a switch-on detection signal of one of the switches for a predetermined short time. If a switch-on detection signal is output from the other switch within the specified time (that is, after pressing one of the switches to release the switch operation, the other switch is pressed within a predetermined short time). When the switch-on detection output is output from both of the two switches 31 and 32 (that is, one of the switches is kept pressed while the other is being pressed). An appropriate method such as a method of determining that the switch is pressed at the same time) as a simultaneous pressing operation can be employed.

  If the switch 31 and the switch 32 are simultaneously pressed in the “first operation mode” state, the operation mode setting is switched to the “second operation mode” and the velocity curve value is currently selected. From any one of the curves A to D, it is switched to the fix.

  In addition, when the switch 31 and the switch 32 are simultaneously pressed in the “second operation mode” state, the operation mode is switched to the “first operation mode” and the velocity curve value is changed from 4 to 4. It switches to any one of the two curves A to D. Here, when the operation mode setting is switched from the “second operation mode” to the “first operation mode”, that is, when the value of the velocity curve is switched from the fix to any one of the curves A to D, The curves A to D set to the value of the velocity curve are any of the curves A to D set immediately before the fix is set, that is, the general option (curves A to D selected last from the current point of view). Either).

  As is apparent from the above, the switches 31 and 32 for setting the value of the velocity curve include [1] “first operation mode” in which either the switch 31 or the switch 32 is operated alone, and [2]. The switch 31 and the switch 32 are operated in two operation modes, ie, a “second operation mode” in which both the switches 31 and 32 are pressed simultaneously. That is, the switches 31 and 32 constitute a “setting operation element” described in the claims.

  FIG. 5 is a configuration example of a buffer area used for setting a velocity curve value. This buffer is secured in the RAM 12 of the musical tone control device 1 as described above. As shown in FIG. 5, the buffer area used for setting the velocity curve value includes a buffer (currently used option) 33 for storing the value of the currently used velocity curve, and general options (curve A, A buffer (selection value) 34 for storing a general option selected last among the curve B, curve C and curve D), a buffer (fix value) 35 for storing a fix value, and an operation mode setting state. Four buffers (operation mode) 36 for storing the data to be shown are provided.

  The values stored in the in-use option buffer 33 are, for example, numerical numbers 1 to 4 assigned to general options (curve A, curve B, curve C, and curve D) and special options (fixes). It is assumed to be a value composed of a continuous value of five stages with the numerical value number 5 represented. When either one of the switch 31 or the switch 32 is operated in the first operation mode, the value in the in-use option buffer 33 is the value of the general option newly selected according to the operation (any of the curves A to D). Is updated. Further, the value of the in-use option buffer 33 is changed from a general option (any one of the curves A to D) to a fix, or from a fix to a general option (curves A to A) in accordance with the simultaneous pressing operation of the switches 31 and 32. D). Further, when a fix is selected for the value in the in-use option buffer 33, the current fix value (the value stored in the fix value buffer 35) is also set in the in-use option buffer 33. In the following, the value of the currently selected option among general options (curves A to D) is referred to as “selected value”.

  The value stored in the selection value buffer 34 is the current selection value, that is, the value of the last selected general option (any one of the curves A to D). In the first operation mode, when either the switch 31 or the switch 32 is operated, the value of the selection value buffer 34 is updated according to the operation. While the second operation mode is set, that is, while the fix is set in the in-use option buffer 33, the general selected last is regardless of the operation of either the switch 31 or the switch 32. Are stored in the selection value buffer 34 as selection values. As a result, when the operation mode is switched from the second operation mode to the first operation mode, that is, when the value of the velocity curve is changed from the fix to the general option, the selection is made immediately before the previous fix is set. The general option (any one of the curves A to D) that has been set can be restored as a value newly set in the in-use option buffer 33. This selection value buffer 34 constitutes “storage means” described in the claims.

  The fix value stored in the fix value buffer 35 is a parameter that takes continuous values in 128 steps from 0 to 127, for example. In the second operation mode, when either the switch 31 or the switch 32 is operated, the value of the fix value buffer 35 is updated according to the operation. Therefore, while the first operation mode is set, the last set fix value is held in the fix value buffer 35 regardless of the operation of the switch 31 or the switch 32. As a result, when a fix is set to the value of the velocity curve, that is, when the operation mode is switched from the first operation mode to the second operation mode, the currently used fix value set by the user is selected. It can be set in the buffer 33.

  The operation mode buffer 36 stores a value representing one of the currently set operation modes, that is, the “first operation mode” or the “second operation mode”. The value of the operation mode buffer 36 is sequentially switched between the “first operation mode” and the “second operation mode” every time the switch 31 and the switch 32 are simultaneously pressed.

  Hereinafter, with reference to the flowcharts shown in FIGS. 6 to 9, an example of a procedure of operations executed by the CPU 10 of the musical tone control device 1 according to the operation of the increment switch 31 and the decrement switch 32 will be described.

  FIG. 6 is a flowchart showing an example of a processing procedure for detecting the operation state of the increment switch (INC switch) 31 and the decrement switch (DEC switch) 32. This process is a process that is activated when at least one of the increment switch 31 and the decrement switch 32 is operated. The main process (not shown) that is activated when the musical sound control device 1 is turned on is a process including a step of detecting operations of various switches on the panel surface, and is repeatedly activated at a predetermined cycle. Therefore, when the user newly operates at least one of the switch 31 and the switch 32, the new operation is detected in the main process, and the process illustrated in FIG. 6 is activated accordingly.

  In step S1 of FIG. 6, the detected switch operation includes the following three operations, that is, [1] operation of both the increment switch 31 and the decrement switch 32 (simultaneous pressing operation), or [2] increment. By determining whether the switch 31 is operated or [3] the decrement switch 32 is operated, at least one of the switch 31 and the switch 32 is either the first operation mode or the second operation mode. It is determined whether it was operated in the operation mode. This processing corresponds to the operation of the “operation detection means” described in the claims.

  When the operation mode of the switch operation determined in step S1 is [1] simultaneous pressing operation of the increment switch 31 and the decrement switch 32, an operation mode switching process shown in FIG. 7 is performed (step S2). When the switch operation is a single operation of [2] increment switch 31, the increment control process shown in FIG. 8 is performed (step S3). When the switch operation is a single operation of [3] decrement switch 32, the decrement control process shown in FIG. 9 is performed (step S4).

  FIG. 7 is a flowchart showing an example of the procedure of the mode switching process in step S2 of FIG. In step S5 of FIG. 7, the current setting state of the operation mode is checked based on the value stored in the operation mode buffer 36 (see FIG. 5). If the second operation mode is set (YES in step S6), the operation mode is switched from the second operation mode to the first operation mode by the simultaneous pressing operation of the switch 31 and the switch 32 this time. Accordingly, the value of the operation mode buffer 36 is rewritten to the first operation mode (step S7), and the selection value stored in the selection value buffer 34 is written to the new value of the in-use option buffer 33 (step S8). ), The value of the velocity curve is changed from a fix to a general option (any one of curves A to D) set immediately before the fix is set. As a result, the first operation mode is set as the operation mode, and one of the four types of curves A to D is selected as the value of the velocity curve.

  On the other hand, when the first operation mode is set as the operation mode (NO in step S6), the operation mode is changed from the first operation mode to the second operation mode by the simultaneous pressing operation of the switch 31 and the switch 32 this time. Switch to operation mode. Accordingly, the value in the operation mode buffer 36 is rewritten to the second operation mode (step S9), a fix is set to a new value in the in-use option buffer 33 (step S10), and the value in the fix value buffer 35 is set. Is set to the current fix value in the in-use option buffer 33. As a result, the second operation mode is set as the operation mode, and a fix is selected as the value of the velocity curve. The processing shown in FIG. 7 corresponds to the operation of “second parameter setting means” described in the claims.

  Even in the configuration in which the operation mode buffer 36 is not provided, the current operation mode state can be checked depending on whether or not the current value of the in-use option buffer 33 is “fix”. Specifically, in step S5 of FIG. 7, the current value is checked with reference to the in-use option buffer 33. If [1] is a fix, it is determined that the second operation mode is currently set. (YES in step S6), the value in the in-use option buffer 33 is rewritten with the selected value stored in the selection value buffer 34, and [2] the option other than the fix is stored in the in-use option buffer 33 For example, it is determined that the first operation mode is currently set (NO in step S6), and the value in the in-use option buffer 33 may be rewritten to a fix.

  FIG. 8 is a flowchart showing an example of the procedure of the increment control process in step S3 of FIG. When the operation of the increment switch 31 is detected, in step S12, the current setting state of the operation mode is checked with reference to the operation mode buffer 36 (see FIG. 5). If the operation mode is the second operation mode (YES in step S13), the value in the fix value buffer 35 is increased by one level (step S14), and the fix value newly set in step S14 is changed to the current fix. A value is set in the in-use option buffer 33 (step S15). If the operation mode is set to the first operation mode (NO in step S13), the selection value in the selection value buffer 34 includes the next option (for example, the curve B for the curve A) that is currently set. The “next option” is selected (step S16), and the selection value newly selected in step S16 is set in the in-use option buffer 33 as the current velocity curve value (step S17). Here, the options that can be selected by operating the increment switch 31 in the first operation mode are only one of the curves A to D (that is, general options).

FIG. 9 is a flowchart showing an example of the procedure of the decrement control process in step S4 of FIG. The decrement control operation is the same as the increment control process shown in FIG. 8 except that the value is “decreased” in accordance with the operation of the decrement switch 32. That is, when the operation of the decrement switch 32 is detected, if the operation mode is set to the second mode of operation, step S18, S19, by the processing of S 20 and S 21, the value of the fixed value buffer 35 And the changed fix value is set as the current fix value in the in-use option buffer 33. If the operation mode is set to the first operation mode, the selection value in the selection value buffer 34 is displayed in the selection value in the selection value buffer 34 by the process of steps S18, S19, S22, and S23. An option (for example, the curve C with respect to the curve D is “the previous option”) is selected, and the newly selected value is set in the in-use option buffer 33 as the value of the current velocity curve. Here again, the option that can be selected by operating the decrement switch 32 in the first operation mode is only one of the curves A to D (that is, a general option).

  When the first operation mode is set by the increment control process shown in FIG. 8 and the decrement control process shown in FIG. 9, the selection value is set, and when the second operation mode is set. The fix value can be changed by operating either the switch 31 or the switch 32. The processing shown in FIGS. 8 and 9 corresponds to the operation of “first parameter setting means” described in the claims.

  Finally, an example of the procedure of the performance operation detection process of the keyboard 13 will be described with reference to the flowchart of FIG. The above-described main processing includes a step of detecting a key depression on the keyboard 13, thereby periodically scanning a key depression operation on the keyboard 13. When the generation of a new key press is detected in the main process, the process of FIG. 10 is activated. When a new key depression is detected, the performance operator detection circuit 17 detects the key depression operation (key-on), the pitch data (note number) of the key that has been depressed, and the strength of the key depression. Are detected.

  When the key pressing operation is detected, the value of the velocity curve set in the currently used option buffer 33 at the time when the key pressing operation is performed is checked in step S24, and the currently set velocity curve value is checked. Read the curve information corresponding to. If the currently set velocity curve value is one of the curves A to D (when the operation mode is the first operation mode), the information on any of the currently set curves A to D (for example, data) Table) from the ROM 11 or RAM 12, and if the currently set velocity curve value is a fix (when the operation mode is the second operation mode), the fix currently set in the in-use option buffer 33 Read the value. In step S25, a velocity value corresponding to the detected key depression strength is determined based on the read curve information. When any one of the curves A to D is set, the output characteristics of the velocity value corresponding to the key pressing strength are different for each of the curves A to D. Therefore, the currently set curves A to D are different. According to the characteristic of D, a velocity value corresponding to the key pressing strength is output. When a fix is selected, the read fix value is output as a velocity value regardless of the key depression strength. Then, sound generation instruction data including the key-on data, the note number data corresponding to the pitch of the pressed key and the velocity value output in step S25 is generated (step S26). The generated sound generation instruction data is transmitted to the PC 2 via the external communication I / F 16 (step S27). Thus, the musical tone control device 1 can give the PC 2 a sound generation instruction corresponding to the detected key press. The sound generation instruction data may be data in an appropriate data format conventionally known, such as MIDI data.

  The PC 2 receives the sound generation instruction data transmitted in step S27 of FIG. 10 from the musical sound control device 1, and uses the received sound generation instruction data as a corresponding sound source (in-use sound source) 3 among the plurality of software sound sources 3. To generate a musical sound corresponding to the received sound generation instruction data using the sound source 3 in use. The “corresponding sound source (sound source in use)” 3 is one sound source 3 that is set as the output destination of the sound generation instruction data when the sound generation instruction data is generated, as described above. The user can set any one of the plurality of sound sources 3 provided in the PC 2 as the output destination of the sound generation instruction data from either the musical tone control apparatus 1 or the PC 2.

  As described above, according to this embodiment, the value (option) of the velocity curve can be set only by operating one of the increment switch 31 and the decrement switch 32 alone in the first operation mode. Further, the fix value can be changed only by operating either the increment switch 31 or the decrement switch 32 independently in the second operation mode. Moreover, the setting state of the operation mode can be switched between the first operation mode and the second operation mode only by simultaneously pressing the increment switch 31 and the decrement switch 32. Therefore, the velocity curve value (option) setting and the constant value setting when the fix is selected can be easily and quickly performed using only two pairs of switches 31 and 32. Has an effect. As described above, in the electronic musical instrument system configuration in which a plurality of external sound sources 3 are controlled by one musical sound control device 1, there are situations in which the value of the velocity curve is frequently changed and situations in which the velocity curve value is desired to be changed quickly. Often occurs. In this regard, according to the present invention, the value of the velocity curve can be changed easily and quickly. Therefore, the parameter setting device of the present invention is used as a musical sound control device for controlling a plurality of externally connected sound sources 3. By applying to 1, a remarkable effect can be obtained. Further, even if the operation means for setting parameters is newly provided, the increase in the number of parts and the cost can be suppressed to the necessary minimum. This is advantageous in terms of simplification and miniaturization of the musical sound control apparatus.

  In the above-described embodiment, the first operation mode is a state in which a general option (any one of the curves A to D) is set to the value of the velocity curve and the switch 31 or 32 is selected. The second operation mode is a mode in which the switch 31 or 32 is used for changing the fix value in a state where a special option (fix) is set to the value of the velocity curve. An example is shown. However, the present invention is not limited to this, and the first operation mode may be a mode in which the switch 31 or 32 is used to select all options of the velocity curve including the fix. That is, in the first operation mode, the value of the velocity curve is sequentially changed in the order of curve A, curve B, curve C, curve D, fix, curve A... According to the operation of the increment switch 31. Depending on the operation of the decrement switch 32, the curve D, curve C, curve B, curve A, fix, curve D,... In this case, the second operation mode may be a mode in which the fix value is simply changed by the operation of either the switch 31 or the switch 32. That is, when the operation mode is switched to the second operation mode, the value of the velocity curve is not changed to the fix, and the current state may be maintained.

  Moreover, in the said Example, simultaneous press operation of the increment switch 31 and the decrement switch 32 was mentioned as an example of the 2nd operation mode. The simultaneous pressing operation of the switch 31 and the switch 32 described in the above embodiment can clearly distinguish the difference from the first operation mode in which only one of the switch 31 or the switch 32 is operated. However, the second operation mode is not limited to this, and it is only necessary to press the switch that can distinguish the difference from the first operation mode. For example, other appropriate operation modes such as a long press operation of one or both of the increment switch 31 and the decrement switch 32 or a double click (an operation of pressing the switch twice within a predetermined short time) are used as the second operation. It can be adopted as an embodiment.

However, the musical tone control device 1 is shown in the embodiment. As long as it can function as a controller for controlling the tone generation of the tone generator 2 of the electronic musical instrument system, it may be constituted by an electronic instrument having a mechanism for generating a tone. Further, the performance operator 13 of the musical tone control device 1 is not limited to the keyboard, and may take any form as long as it can input a musical tone generation instruction including the strength of the performance operation.

In addition, the musical tone generating device 2 is not limited to a PC and may be a plurality of devices as long as it has a mechanism for generating a musical tone corresponding to the pronunciation instruction upon receiving a sound generation instruction from the externally connected musical tone control device 1.
