Hereinafter, embodiments of the present invention will be described with reference to the drawings.
A. Constitution
FIG. 1 is a block diagram showing the overall configuration of an electronic musical instrument 100 which is an embodiment provided with a parameter editing apparatus according to the present invention. In FIG. 1, the CPU 10 sets the operation state of each part of the musical instrument based on the operation event generated in response to the switch operation of the operation unit 14 or generates a note event corresponding to the performance information supplied from the keyboard 13. Is sent to the sound source 17 to form a musical tone. The processing operation of the CPU 10 according to the gist of the present invention will be described in detail later.

  The ROM 11 stores various control programs loaded on the CPU 10. The various control programs include a main routine to be described later, switch processing called from the main routine, and keyboard processing. The switch process includes a mode switch process, an edit start switch process, and an edit end switch.

  The RAM 12 includes a data area DE and a work area WE as illustrated in FIG. In the data area DE of the RAM 12, for example, parameter types (1) to (M) respectively assigned to a plurality of keys in a predetermined key range (accompaniment key range, etc.) of the keyboard 13 are stored. The parameter types (1) to (M) indicate types of musical sound parameters to be referred to when the sound source 16 forms musical sounds. Specific parameter types include, for example, a volume envelope related to volume control, a cut-off frequency related to tone color control, a pitch bend related to pitch control, and a reverb related to an effect (effect addition).

  A plurality of parameter values (1) to (N) are stored in one parameter type. As will be described later, the parameter types (1) to (M) assigned to each of the plurality of keys of the keyboard 13 are selected by pressing one of the keys, and constitute the selected parameter type. The parameter values (1) to (N) to be read are read and stored in the parameter value area PE in the work area WE. That is, in the parameter value area PE in the work area WE, a plurality of parameter values (1) constituting a parameter type selected from a plurality of parameter types (1) to (M) stored in the data area DE. ) To (N) are copied.

  In the work area WE, a mode flag MF, an edit flag EF, and a key number KN are temporarily stored. The mode flag MF is set to “0” or “1” in accordance with an ON operation of a mode switch described later. When the mode flag MF is “0”, the normal mode is indicated, and when the mode flag MF is “1”, the parameter edit mode is indicated.

  The normal mode is a normal operation mode in which a musical tone is generated in response to a performance operation (press / release key operation). The parameter editing mode is an operation mode in which the key of the keyboard 13 functions as an operation switch, the parameters used for generating a musical tone by key operation are edited, and the musical tone generated using the edited parameter is checked for pronunciation. Details will be described later. The parameter editing here refers to selecting one of the parameter types (1) to (M) and designating one of a plurality of parameter values (1) to (N) constituting the selected parameter type. The processing operation for updating the parameter value.

  The edit flag EF indicates that the parameter type has been selected when the parameter edit mode (when the mode flag MF is “1”) is “1” and no parameter type is selected when the parameter is “0”. Represents. As will be described later, the edit flag EF is in a state in which the parameter type has been selected (flag value “1”) by the key pressing operation after the edit start switch is turned on, and the parameter type is not selected by the on operation of the edit end switch. Return to the state (flag value “0”). The key number KN temporarily stores the key number of the key pressed when selecting the parameter type or the key number of the key pressed when selecting the parameter value from the selected parameter type. .

  The configuration of the embodiment will be described with reference to FIG. 1 again. In FIG. 1, a keyboard 13 generates performance information including a key-on / key-off signal, a key number, velocity, and the like corresponding to a press / release key operation (performance operation) and supplies the performance information to the CPU 10. The operation unit 14 includes various switches provided on a console panel (not shown), generates a switch event corresponding to the operated switch, and supplies the switch event to the CPU 10. The main switches according to the gist of the present invention include the mode switch, the edit start switch, and the edit end switch described above. Note that the mode switch functions as a so-called toggle button switch, and is alternately set to ON and OFF every time it is pressed (ON).

  The display unit 15 includes an LCD panel and a driver, and displays various screens according to display control signals supplied from the CPU 10. Specifically, if the electronic musical instrument 100 is in a normal operation mode in which a musical tone is generated in response to a performance operation (press / release key operation), various setting states and musical instrument operation states are displayed on a normal screen. On the other hand, in the parameter editing mode in which the keys of the keyboard 13 function as operation switches to edit the parameters used for generating musical sounds by key operation and to generate the musical sounds generated using the edited parameters, the parameter area PE of the RAM 12 is used. A parameter selection screen for displaying a list of parameter types (1) to (M) stored in the parameter list and a parameter editing screen for displaying a list of a plurality of parameter values (1) to (N) constituting the selected parameter type are displayed. .

  The sound source 16 is configured by a well-known waveform memory reading method and includes a plurality of sound generation channels that perform time-division operation. The sound source 16 generates and outputs musical tone data corresponding to musical tone parameters supplied from the CPU 10. The sound system 17 D / A converts the musical tone data output from the sound source 16 into an analog musical tone signal, and then amplifies the signal and emits the sound from the speaker.

B. Operation Next, the operation of the electronic musical instrument 100 configured as described above will be described with reference to FIGS. In the following, the main routine executed by the CPU 10 of the electronic musical instrument 100, the switch process called from the main routine, and the keyboard process will be described.

(1) Operation of Main Routine When the electronic musical instrument 100 is powered on by operating the power switch, the CPU 10 executes the main routine shown in FIG. 3 and proceeds to Step SA1 to execute initialization for initializing each part of the musical instrument. When the initialization is completed, the process proceeds to the next step SA2, where a parameter type to be edited is selected under the parameter editing mode, or a switch process for returning from the parameter editing mode to the normal mode is executed.

  Next, in step SA3, parameter editing is performed to change the parameter type selected from the plurality of parameter values (1) to (N) constituting the parameter type selected according to the key depression in the parameter editing mode to a desired parameter value, A keyboard process for generating a musical tone generated using the parameter values updated by the parameter editing is executed.

  Then, when the process proceeds to step SA4, for example, in the normal mode, after performing other processes such as applying an effect to the generated musical sound, the process returns to step SA2. Thereafter, the processes in steps SA2 to SA4 are repeatedly executed until the electronic musical instrument 100 is powered off.

(2) Operation of Switch Processing Next, the operation of switch processing will be described with reference to FIG. When this process is executed via step SA2 (see FIG. 3) of the main routine described above, the CPU 10 proceeds to step SB1 and executes a mode switch process. In the mode switch process, as described later, every time the mode switch is pressed (ON operation), either the normal mode (mode flag MF is “0”) or the parameter edit mode (mode flag MF is “1”). When the mode is changed to the parameter editing mode, the parameter types (1) to (M) stored in the data area DE of the RAM 12 are listed to which keys of the keyboard 13 are assigned. A selection screen is displayed on the display unit 15.

  Subsequently, in step SB2, an edit start switch process is executed. In the edit start switch process, in the parameter edit mode, after the user turns on the edit start switch, when the key of the key number KN to which the parameter type desired to be edited is further assigned with reference to the parameter selection screen is pressed, the parameter type (KN) is selected, and a plurality of parameter values (1) to (N) constituting the selected parameter type (KN) are stored in the parameter value area PE in the work area WE of the RAM 12, while the key is pressed. A list of the keys on the keyboard 13 to which the plurality of parameter values (1) to (N) constituting the parameter type (KN) selected according to is assigned is displayed on the parameter editing screen.

  Next, in step SB3, an edit end switch process is executed. In the edit end switch process, as described later, when the user turns on the edit end switch in the parameter edit mode, the edit flag EF is reset to zero and the parameter type is not selected and stored in the data area DE of the RAM 12. A parameter selection screen that lists which keys of the keyboard 13 are assigned the parameter types (1) to (M) to be displayed is displayed on the display unit 15. Thereafter, the process proceeds to step SB4, and other switch processes such as selecting the effect type to which the effect is selected by selecting the tone color of the generated musical sound are executed, and this process is completed.

(3) Mode Switch Processing Operation Next, the mode switch processing operation will be described with reference to FIG. When this processing is executed through the above-described switch processing step SB1 (see FIG. 4), the CPU 10 proceeds to step SC1 shown in FIG. 5 to determine whether or not a mode switch is pressed (ON operation). To do. If the pressing operation (ON operation) is not performed, the determination result is “NO”, and the present process ends. However, if the pressing operation (ON operation) is performed and the determination result is “YES”, the process proceeds to step SC2, and the mode flag MF Invert.

  Subsequently, in step SC3, it is determined whether or not the inverted mode flag MF is “0”, that is, the normal mode. If the reversed mode flag MF is the normal mode of “0”, the determination result is “YES”, the process proceeds to step SC4, a normal screen (not shown) is displayed on the display unit 15, and the present process ends. Note that the normal screen displays various setting states and operation states of the musical instrument 100.

  On the other hand, if the inverted mode flag MF is “1”, that is, the parameter editing mode, the determination result in step SC3 is “NO”, and the process proceeds to step SC5. In step SC5, the parameter types (1) to (M) stored in the data area DE (see FIG. 2) of the RAM 12 are set to, for example, each key from the lowest to the highest note of the accompaniment key range on the keyboard 13, etc. A parameter selection screen (not shown) for displaying a list of keys to be assigned is displayed on the display unit 15 and the present process is terminated.

  Thus, in the mode switch process, every time the mode switch is pressed (ON operation), either the normal mode (mode flag MF is “0”) or the parameter editing mode (mode flag MF is “1”). When the parameter editing mode is changed to the parameter editing mode, parameter selection (1) to (M) stored in the data area DE of the RAM 12 is listed to which key of the keyboard 13 is assigned. The screen is displayed on the display unit 15.

(4) Operation of Edit Start Switch Process Next, the operation of the edit start switch process will be described with reference to FIG. When this processing is executed via the above-described switch processing step SB2 (see FIG. 4), the CPU 10 proceeds to step SD1 shown in FIG. 6, and the mode flag MF is “1”, that is, in the parameter editing mode. It is determined whether or not.

  If not in the parameter edit mode, the determination result in step SD1 is “NO”, and the present process ends. If in the parameter edit mode, the determination result in step SD1 is “YES”, and the process proceeds to step SD2. . In step SD2, it is determined whether or not the edit flag EF is “0”, that is, the parameter type is not selected. If the parameter type is not selected, the determination result is “YES”, the process proceeds to step SD3, and it is determined whether or not the editing start switch is turned on. On the other hand, if the edit flag EF is “1”, that is, if the parameter type has been selected, the determination result in step SD2 is “NO”, and the process proceeds to step SD4 to determine whether the edit start switch has been turned on. To do.

  Next, the determination in step SD3 and step SD4 is as follows: “when the edit start switch is not turned on”, “when the edit start switch is turned on to select a parameter type”, and “another parameter type is selected. The explanation of the operation will be divided into “when the edit start switch is turned on”.

a. When the edit start switch is not turned on When the edit start switch is not turned on regardless of whether editing is in progress (edit flag EF is “1”) or editing is not being performed (edit flag EF is “0”) The determination results of step SD3 or step SD4 described above are all “NO”, and the present process ends.

b. When the edit start switch is turned on to select the parameter type In this case, the determination result in step SD3 described above is “YES”, the process proceeds to step SD5, and the key number is initialized. Subsequently, in step SD6, it is determined whether or not the key having the key number has been pressed. If the key is not depressed, the determination result is “NO”, the process proceeds to step SD8, and the key number is incremented to be incremented.

  In step SD9, it is determined whether or not the incremented key number has exceeded the final value, that is, whether or not the key depression has been determined for all the keys to which the parameter types (1) to (M) are assigned. to decide. If it has not been determined for all keys to which parameter types (1) to (M) are assigned, the determination result is “NO”, and the process returns to step SD6 described above. Thereafter, in steps SD6 to SD9, the presence or absence of key depression is determined every time the key number is incremented until the key number exceeds the final value.

  For example, it is assumed that the key number KN of the key to which the parameter type (KN) is assigned is pressed. Then, the determination result in step SD6 is “YES”, and the process proceeds to step SD7, where a plurality of parameter values (1) to (N) constituting the parameter type (KN) corresponding to the key number KN of the key that has been pressed. Are read from the data area DE of the RAM 12 and stored in the parameter value area PE in the work area WE of the RAM 12.

  Thus, the parameter type (KN) is selected according to the key depression of the key number KN, and a plurality of parameter values (1) to (N) constituting the selected parameter type (KN) are stored in the parameter value area PE. After the storage, when it is determined that all keys to which the parameter types (1) to (M) are assigned have been pressed, the determination result in step SD9 is “YES”, and the process proceeds to step SD10. The edit flag EF is set to “1” to indicate a state in which the parameter type has been selected.

  Next, in step SD11, a parameter editing screen (not shown) is displayed on the display unit 15. In the parameter editing screen, the type name of the selected parameter type (KN) is displayed, and the parameter values (1) to (N) of the parameter type (KN) selected according to the key press are displayed on the keyboard 13 respectively. Lists whether a key has been assigned.

  Subsequently, in step SD12, one of the parameter values (1) to (N) displayed as a list on the parameter editing screen is highlighted, for example, the default parameter value or the parameter value used last time (for example, This display is finished with a reverse display or blink display.

c. When the editing start switch is turned on to select another parameter type When the editing start switch is turned on again in a state where some parameter type has already been selected, the determination result in step SD4 described above is “YES”. Then, the process proceeds to step SD13, and the parameter values (1) to (N) of different parameter types are highlighted on the parameter editing screen, and the process is finished.

  As described above, in the edit start switch process, in the parameter edit mode, after the user turns on the edit start switch, the key of the key number KN to which the parameter type to be edited is assigned with reference to the parameter selection screen is pressed. Then, the parameter type (KN) is selected, and a plurality of parameter values (1) to (N) constituting the selected parameter type (KN) are stored in the parameter value area PE in the work area WE of the RAM 12. On the other hand, a list of the keys on the keyboard 13 to which the plurality of parameter values (1) to (N) constituting the parameter type (KN) selected according to the key depression is assigned is displayed on the parameter editing screen.

(5) Operation of Edit End Switch Process Next, the operation of the edit end switch process will be described with reference to FIG. When this process is executed via the above-described switch process step SB3 (see FIG. 4), the CPU 10 advances the process to step SE1 shown in FIG. 7, and the mode flag MF is “1”, that is, in the parameter edit mode. It is determined whether or not. If it is not the parameter edit mode, the determination result is “NO”, and this process is completed. If it is in the parameter edit mode, the determination result is “YES”, and the process proceeds to step SE2.

  In step SE2, it is determined whether or not the editing end switch has been turned on. If the edit end switch is not turned on, the determination result is “NO”, and this processing is completed. If the edit end switch is turned on, the determination result is “YES”, and the process proceeds to step SE3, where the edit flag EF is reset to zero. The parameter type is not selected. Thereafter, the process proceeds to step SF4, and a parameter selection screen is displayed on the display unit 15 for displaying a list of keys assigned to the parameter types (1) to (M) stored in the data area DE of the RAM 12. This process is finished.

  Thus, in the edit end switch process, when the user turns on the edit end switch in the parameter edit mode, the edit flag EF is reset to zero and the parameter type is not selected, and is stored in the data area DE of the RAM 12. A parameter selection screen is displayed on the display unit 15 to display a list of which keys on the keyboard 13 are assigned to each of the parameter types (1) to (M).

(6) Operation of Keyboard Processing Next, the operation of keyboard processing will be described with reference to FIGS. When this process is executed via step SA3 (see FIG. 3) of the main routine described above, the CPU 10 advances the process to step SF1 shown in FIG. 8, and the mode flag MF is “0”, that is, in the normal mode. It is determined whether or not. If it is under the normal mode, the determination result is “YES”, and steps SF2 to SF8 are executed.

  On the other hand, if the mode flag MF is “1”, that is, in the parameter editing mode, the determination result in step SF1 is “NO”, the process proceeds to step SF9 shown in FIG. 9, and the editing flag EF is “0”. That is, it is determined whether or not the parameter type is not selected. If the parameter type is not selected, the determination result is “YES”, and Steps SF10 to SF18 are executed. On the other hand, if the edit flag EF is “1”, that is, if the parameter type has been selected, the determination result in step SF9 is “NO”, and steps SF19 to SF28 shown in FIG. 10 are executed.

  Therefore, in the following, the keyboard processing operations are divided into "when in normal mode", "when parameter type is not selected under parameter edit mode" and "when parameter type is already selected under parameter edit mode". Proceed with the explanation.

a. Under normal mode If the normal mode (mode flag MF is "0"), the determination result in step SF1 shown in FIG. 8 is "YES", the process proceeds to step SF2, and the key number is initialized. Subsequently, in step SF3, a key change is determined for the key having the key number. If there is no key change, the process proceeds to step SF7, where the key number is incremented and incremented, and in the subsequent step SF8, it is determined whether the incremented key number exceeds the final value. If the stepped key number does not exceed the final value, the determination result in step SF8 is “NO”, and the process returns to step SF3.

  Then, for example, it is assumed that the key with the stepped key number is pressed, and this causes a key-on key change. Then, based on the determination result of step SF3, the process proceeds to step SF4, where a note-on event is created based on performance information (key-on signal, key number, velocity, etc.) generated by the keyboard 13 when the key is pressed. The note-on event is sent to the sound source 16. As a result, the sound source 16 generates a musical sound according to the note-on event. Thereafter, the process proceeds to steps SF7 to SF8. When the incremented key number exceeds the final value, the determination result in step SF8 becomes “YES”, and the present process is temporarily ended.

  Thereafter, this processing is executed again through step SA3 (see FIG. 3) of the main routine, and it is assumed that the key that has been pressed is released and a key-off key change occurs. Then, based on the determination result of step SF3, the process proceeds to step SF5 to create a note-off event based on performance information (key-off signal and key number) generated by the keyboard 13 by releasing the key, and in the subsequent step SF6, the generated note-off is generated. The event is sent to the sound source 16. As a result, the tone generator 16 mutes the tone being generated.

  As described above, in the normal mode, the tone generator 16 is instructed to generate a tone according to the note-on event created based on the performance information (key-on signal, key number, velocity, etc.) generated by the keyboard 13 when the key is pressed. Normal keyboard processing for instructing the sound source 16 to mute the musical tone is performed in accordance with a note-off event generated based on performance information (key-off signal and key number) generated by the keyboard 13 by the key.

b. When the parameter type is not selected under the parameter edit mode When the parameter type is not selected under the parameter edit mode, the determination result in step SF1 shown in FIG. 8 is “NO”, and the process proceeds to step SF9 shown in FIG. The determination result here is “YES”, and the process proceeds to step SF10 to initialize the key number.

  Next, in step SF11, a key change is determined for the key with the key number. If there is no key change, the process proceeds to step SF17, where the key number is incremented and incremented, and in the subsequent step SF18, it is determined whether the incremented key number exceeds the final value. If the stepped key number does not exceed the final value, the determination result in step SF18 is “NO”, and the process returns to step SF11.

  Then, for example, it is assumed that the key with the stepped key number is pressed, and this causes a key-on key change. Then, the process proceeds to step SF12 based on the determination result in step SF11, and the parameter type corresponding to the key number KN of the key pressed from the parameter types (1) to (M) stored in the data area DE of the RAM 12 (KN) is selected, and the type name of the selected parameter type (KN) is displayed on the display unit 15.

  Subsequently, in step SF13, a note-on event is generated in which a musical tone having a pitch (key number) of a specific key designated in advance is generated with the parameter type having the type name displayed in step SF12. For example, if the pitch (key number) of a specific key specified in advance is “A4 tone” and the parameter type of the type name displayed in step SF12 is a cutoff frequency related to tone control, the predetermined cutoff frequency A note-on event for instructing the pronunciation of “A4 sound” controlled by DCF is created.

  In step SF16, the created note-on event is sent to the sound source 16. Then, the sound source 16 generates a musical tone having a specific pitch modified with the parameter type having the type name displayed in step SF12. Thereby, the user can grasp the contents of the parameter type by listening to the musical sound of the specific pitch. Next, in step SF17, the key number is incremented and incremented, and in the subsequent step SF18, it is determined whether or not the incremented key number exceeds the final value. When the stepped key number exceeds the final value, the determination result is “YES”, and the process is temporarily finished.

  Thereafter, this processing is executed again through step SA3 (see FIG. 3) of the main routine, and it is assumed that the key that has been pressed is released and a key-off key change occurs. Then, based on the determination result in step SF11, the process proceeds to step SF14 and instructs the display unit 15 to delete the type name of the parameter type (KN) displayed in step SF12. Thereafter, the process proceeds to step SF15 to create a note-off event for muting the musical tone of the specific key pitch (key number). In the subsequent step SF16, the created note-off event is sent to the sound source 16.

  As described above, when the parameter type is not selected in the parameter edit mode, the key number KN of the key pressed from the parameter types (1) to (M) stored in the data area DE of the RAM 12 is set. After selecting the corresponding parameter type (KN) and displaying the type name of the selected parameter type (KN) on the display unit 15, the musical tone of the pitch (key number) of the specific key modified with the selected parameter type is displayed. When the sound source is instructed to the sound source 16 and the key that has been pressed is released, the sound source 16 is instructed to mute the musical sound.

c. When the parameter type has been selected in the parameter edit mode When the parameter type has been selected in the parameter edit mode, the determination result in step SF1 shown in FIG. 8 is “NO”, and the determination result in step SF9 shown in FIG. Becomes “NO”, and the process proceeds to Step SF 19 shown in FIG. 10 to initialize the key number.

  Next, in step SF20, a key change is determined for the key with the key number. If there is no key change, the process proceeds to step SF27 where the key number is incremented and incremented, and in the subsequent step SF28, it is determined whether or not the incremented key number exceeds the final value. If the stepped key number does not exceed the final value, the determination result in step SF28 is “NO”, and the process returns to step SF20.

  Then, for example, it is assumed that the key with the stepped key number is pressed, and this causes a key-on key change. Then, based on the determination result of step SF20, the process proceeds to step SF21, and is designated by the key number KN of the key that has been pressed out of the plurality of parameter values (1) to (N) constituting the selected parameter type. Change to parameter value (KN).

  The parameter values (1) to (N) of the parameter type being selected are the parameter types (1) to (M) stored in the data area DE of the RAM 12 in the edit start switch process (see FIG. 6). ) Are the parameter values (1) to (N) of the parameter type selected by the key number of the key that has been pressed, and the data stored (copied) from the data area DE of the RAM 12 to the parameter value area PE. is there.

  Subsequently, in step SF22, an event (meta event) instructing to change the parameter type and parameter value selected by the key depression is created, and in the subsequent step SF23, the created event (meta event) is sent to the sound source 16. To do. As a result, the sound source 16 interprets and executes the received event (meta event) and changes the parameter value of the instructed parameter type.

  Next, in step SF24, a note-on event for generating a tone having a pitch (key number) of a specific key specified in advance is created. Next, in step SF26, the created note-on event is sent to the sound source 16. Then, the tone generator 16 generates a musical tone having the pitch of the specific key modified with the parameter value of the parameter type changed in accordance with the event (meta event) sent in step SF23. As a result, the user can immediately confirm what musical sound is produced according to parameter editing (change of parameter type and parameter value) by key operation.

  In step SF27, the key number is incremented and incremented. In the subsequent step SF28, it is determined whether or not the incremented key number exceeds the final value. When the stepped key number exceeds the final value, the determination result is “YES”, and the process is temporarily finished.

  Thereafter, this processing is executed again through step SA3 (see FIG. 3) of the main routine, and it is assumed that the key that has been pressed is released and a key-off key change occurs. Then, based on the determination result of step SF20, the process proceeds to step SF25 to create a note-off event for muting the tone of the specific key (key number). In the subsequent step SF26, the generated note-off event is used as the sound source 16. Send to.

  As described above, if the parameter type has been selected in the parameter editing mode, the key number KN of the key pressed from among the plurality of parameter values (1) to (N) constituting the parameter type selected by pressing the key. After instructing the sound source 16 to change to the parameter value (KN) specified in step 1, the tone of the pitch (key number) of the specific key is generated, so that the user can edit the parameter by key operation (parameter type and parameter value). It becomes possible to immediately confirm what kind of musical sound is pronounced according to (change). When the key that has been pressed is released, the sound source 16 is instructed to mute the musical sound.

  As described above, in the present embodiment, a plurality of parameter types (1) to (M) each having a plurality of parameter values (1) to (N) are stored in the RAM 12, and each key of the keyboard 13 is stored. When a plurality of parameter types (1) to (M) are assigned and the parameter type assigned to the key that has been pressed is selected in accordance with the key pressing operation of the keyboard 13, a plurality of parameter types constituting the selected parameter type are selected. When parameter values (1) to (N) are read from the RAM 12 and assigned to each key of the keyboard 13 and the parameter value assigned to the pressed key is designated according to the key pressing operation of the keyboard 13, the parameter value is selected. The generated musical tone is generated by changing to the parameter value specified for the selected parameter type, so you can immediately check what musical tone is produced according to the parameter editing by key operation Can, an effect that.

  In addition, when a parameter value assigned to the depressed key is designated in response to a key depression operation on the keyboard 13, a musical tone formed by changing to the parameter value designated for the selected parameter type is played. By generating a sound by a key operation, it is possible to immediately confirm what kind of musical sound is generated at the same time as the parameter value is changed by the key pressing operation.

  Furthermore, when a plurality of parameter types (1) to (M) are assigned to each key of the keyboard 13 and the parameter type assigned to the key pressed is selected in accordance with the key pressing operation of the keyboard 13, the selection is made. By generating the sound of the selected parameter type by the key pressing operation, it is possible to immediately confirm the type of musical sound to be generated simultaneously with the selection of the parameter type by the key pressing operation.

  As mentioned above, although one Embodiment of this invention was described, this invention is not limited to it, It is included in the invention described in the claim of this-application, and its equivalent range. Hereinafter, each invention described in the scope of claims at the beginning of the present application will be additionally described.
