[0001]
BACKGROUND OF THE INVENTION
The present invention relates to, for example, a sound source control device, an electronic musical instrument, a MIDI system, a sound source control method, and a processing step for carrying out the same, which are used for a device (MIDI device) compliant with the MIDI (Musical Instrument Digital Interface) standard. Is stored in a computer-readable manner.
[0002]
[Prior art]
Conventionally, for example, an electronic musical instrument compliant with the MIDI standard, which is a performance information data transfer standard, is not limited to its own, and various types of musical instruments can be used based on externally generated MIDI standard performance information (16-channel MIDI data). Musical sound can be generated.
[0003]
By the way, in MIDI data, note on / off (key press / key release), velocity (strength at the time of key press), gate time (key press time), and timing (key press) are determined by message data called a voice message. Timing) and the like are defined.
[0004]
Specifically, voice messages define note on / off, control changes that define various effects such as modulation wheels and pedals, program changes that are defined for tone switching, and bend information. Includes pitch wheel change and aftertouch.
[0005]
In particular, the control change is used to control the tone of the sound source (sound source possessed by the electronic musical instrument) to which MIDI data is transmitted, and various effects such as volume, cutoff, and sustain, as will be described later. Defined.
[0006]
The control change is formed by a total of 3 byte data of “Bn”, “CC”, and “vv”, each of which is 1 byte data.
In “Bn”, “B” indicates a control change command, and “n” indicates MIDI channel designation (1 channel to 16 channels).
“CC” indicates a control number having a value of “0” to “127”, and “vv” indicates a value (set value).
[0007]
Examples of effects defined by control changes include the following.
-Effects used in real time during performance (effects related to modulation, breath control, channel volume, expression, pedals, etc.).
・ Effects that change timbre changes and how sounds are played (bank select, portamento, panpot, effects, harmonic intensity, release time, attack time, brightness, etc.).
-Effects that change sound source settings (effects related to data entry, pitch bend sensitivity, fine tune, coarse tune, RPN null, NRPN MSB, NRPN LSB, etc.)
-Effects that change the tone (effects related to cutoff frequency, resonance, etc.)
-Effects that change drum part parameters (effects related to drum installations, etc.).

The system is configured to automatically perform the necessary settings based on the contents of.
Hereinafter, the configuration and operation of the sound source control device 100 will be specifically described.
[0026]
<Configuration of Sound Source Control Device 100>
As shown in FIG. 1, the sound source control device 100 is configured such that the operation panel 110, the MIDI interface 120, the CPU 130, the ROM 140, and the RAM 150 are communicably connected to each other via a bus 160.
[0027]
As the sound source control device 100, for example, as shown by the dotted line in FIG. 1, an electronic musical instrument provided with a keyboard 170, a sound source module 180, an amplifier 181, and a speaker 182 can also be applied.
[0028]
The MIDI interface 120 transmits / receives MIDI data to / from the external sound source 200 (x).
[0029]
In FIG. 1, for the sake of simplicity, only one sound source 200 (x) is connected to the sound source control device 100. However, the number of connections is not limited, and various sound sources are used. May be configured to be connected.
[0030]
The operation panel 110 includes an assignable fader unit 111 including a plurality of faders, as shown in FIG. 2, together with an operator for specifying a setup desired by the user and other various operators.
Here, for simplicity of explanation, the assignable fader unit 111 has eight faders 111 (1) to 111 (8), and various effects are assigned to these faders during setup.
[0031]
The ROM 140 includes a ROM 141 for various programs and a ROM 142 for various parameters.
[0032]
The RAM 150 is used as a working memory or the like. In particular, control change correspondence template data 200 as shown in FIG. 3 and setup correspondence data 300 as shown in FIG. 4 are stored.
[0033]
The control change corresponding template data 200 is data in which an appropriate value immediately after the setup change or any desired value is set according to the characteristics of the various effects defined by the control change, as shown in FIG. In addition, for each control change indicated by the control number CC, an item relating to the state before the setup change (hereinafter referred to as “END item”), an item relating to the state after the setup change (hereinafter referred to as “NEW item”). And “type” items are provided.
[0034]
In the END item, assignment information when leaving the current setup state is set.
For example, the END item includes an end item and a value item. In the end item, “default value output (Df)” or “do nothing (Non)” is set. In the value item, when “default value output (Df)” is set in the end item, the default value is set.
[0035]
In the NEW item, assignment information in a new setup state (at the time of assignment) after leaving the current setup state is set.
For example, the NEW item includes an end item and a value item in the same manner as the item before the setup change (for END). In the end item, “default value output (Df)”, “do nothing (Non)”, or “set value output (Set)” is set. In the value item, when “default value output (Df)” or “output setting value (Set)” is set in the end item, the value is set.
[0036]
The type item is a volume type (0 to 127 (Vol) or the like), a relative value (−50 to 0 to +50 (Rel) or the like), or a switch (0, 127 (SW)). Is set.
[0037]
The setting of various information in the control change correspondence template data 200 in FIG. 3 is configured such that the user can arbitrarily set the information by operating various controls on the operation panel 110, for example. May be. Alternatively, it may be set in advance.
[0038]
The setup-corresponding data 300 includes data (hereinafter referred to as “panel editing data 300”) for each setup pattern that can be designated by the user through the operation panel 110, such as contents (control change) assigned to various operators of the operation panel 110. (#X) ").
Here, since the patterns # 1 to #n can be set up, the panel editing data 300 (# 1) to panel editing data 300 (#n) corresponding to the patterns are configured as the setup corresponding data 300. Is done.
[0039]
Therefore, for example, on the basis of a setup change instruction from the operation panel 110 from the user, the corresponding panel edit data 300 (#x) of the setup correspondence data 300 is read, and MIDI data using this as a control change is generated. And output to the sound source 200 (x). In the sound source 200 (x), after the setup based on the panel edit data 300 (#x) of the MIDI data is performed, the performance is started.
[0040]
The CPU 130 controls the overall operation of the sound source control device 100. For example, a processing program according to a predetermined processing sequence stored in advance in the ROM 141 for the program of the ROM 140 is loaded onto the RAM 150 and executed. Thus, an operation (function) that is a feature of the present embodiment as described later is performed.
[0041]
<Operation of Sound Source Control Device 100>
5 to 10 are flowcharts showing the operation of the sound source control device 100. FIG.
For example, the processing ROM 141 according to the flowcharts of FIGS. 5 to 10 is stored in advance in the program ROM 141. The CPU 130 reads the processing program from the program ROM 141 and executes it. Thereby, the sound source control device 100 operates as follows.
[0042]
[Main processing]: See Fig. 5
First, the CPU 130 detects an operation state from the user on the operation panel 110, and executes processing based on the result (step S401).
[0043]
Next, the CPU 130 executes processing (A / D processing) based on the processing result of step S401 (step S402).
[0044]
Then, after executing the corresponding process as necessary (step S403), the CPU 130 returns to step S401 again, and repeatedly executes the subsequent processing steps.
[0045]
[Panel Processing (Step S401)]: See FIG.
First, after executing a corresponding process (other process) as necessary (step S411), the CPU 130 determines whether or not a setup change has been made according to an operation instruction from the user (step S412).
If the result of this determination is that there is no change in the setup, this processing is terminated as it is, and the processing from the next step S413 is executed only when there is a change in the setup.
[0046]
If the result of determination in step S412 is that there is a setup change, the CPU 130 uses the panel editing data 300 (#x) before the setup change and the setup change in the setup correspondence data 300 (see FIG. 4 above) stored in the RAM 150. With reference to the subsequent panel editing data 300 (#y), the processing of the next steps S413 to S415 is repeatedly executed for each of the eight faders 111 (1) to 111 (8) of the operation panel 110.
[0047]
That is, the CPU 130 first assigns the assignment information (CC_new) to the target fader 111 (n) set in the panel edit data 300 (#y) after the setup change (a new setup state designated by the user this time). It is determined whether or not the assignment information (CC_old) to the target fader 111 (n) set in the panel edit data 300 (#x) before the setup change (previous setup state) is the same (step) S413).
The assignment information here indicates a control number (CC #) defined (assigned) by panel editing data (control change) for the target fader 111 (n).
[0048]
Specifically, for example, when the target fader 111 (n) is the fader 111 (1) and the panel edit data 300 (#x) before the setup change is the panel edit data 300 (# 1), As shown in FIG. 4, the assignment information (CC_old) of fader 111 (1) (Fader1) is “cc64”. Therefore, in step S413, this “cc64” and the assignment information (CC_new) to the fader 111 (1) set in the panel edit data 300 (#y) after the setup change obtained in the same manner as this. Are compared.
[0049]
As a result of the determination in step S413, if the assignment information (CC_new) after the change of the target fader 111 (n) and the assignment information (CC_old) before the change of the target fader 111 (n) are the same information, the CPU 130 Without executing the processing of step S414 and step S415, it is determined whether or not the processing of step S413 to step S415 has been completed for each of all the faders 111 (1) to 111 (8) of the operation panel 110. (Step S416) As a result of this determination, the present process ends only when the process ends. Otherwise, the process returns to step S413 again to execute the process of the next fader 111 (n + 1). Repeat the processing steps.
[0050]
On the other hand, as a result of the determination in step S413, if the assignment information (CC_new) after the change of the target fader 111 (n) and the assignment information (CC_old) before the change of the target fader 111 (n) are not the same information, the CPU 130 After executing the process (CC_old) for the assignment information (CC_old) before the change of the target fader 111 (n) (step S414), the process for the assignment information (CC_new) after the change of the target fader 111 (n) (New processing of CC_new) is executed (step S415).
[0051]
Then, CPU 130 determines whether or not the processing of steps S413 to S415 has been completed for each of all faders 111 (1) to 111 (8) of operation panel 110 (step S416). As a result, the present process is terminated only when the process is terminated. Otherwise, the process returns to step S413 to execute the process of the next fader 111 (n + 1), and the subsequent process steps are repeatedly performed.
[0052]
[END process of CC_old (step S414)]: See FIG.
First, in the control change correspondence template data 200 stored in the RAM 150 (see FIG. 3 above), the CPU 130 is the end item of the END item corresponding to the assignment information (CC_old) before the setup change of the target fader 111 (n). Is acquired (step S421).
[0053]
Specifically, for example, when the target fader 111 (n) is the fader 111 (1), the assignment information (CC_old) of the fader 111 (1) is ““ In the case of cc64 ", since the content of the END item of the END item corresponding to this is" Df "in FIG. 3," Df "is acquired in step S421.
[0054]
Then, the CPU 130 determines whether or not the item content acquired in step S421 is a default value output (Df) (step S422).
[0055]
If the default value output (Df) is set as a result of the determination in step S422, the CPU 130 acquires the default value set in the value item corresponding to the setting item in the control change correspondence template data 200, and assigns it. MIDI data including a control change for setting the effect indicated by the information (CC_old) to the default value is generated (step S423).
[0056]
Specifically, for example, when the target fader 111 (n) is the fader 111 (1), the assignment information (CC_old) of the fader 111 (1) is ““ In the case of cc64 ", the content of the END item of the END item corresponding to this is" Df "in FIG. Also, “0” is set in the value item for this. In such a case, in step S423, MIDI data including a control change in which the effect (“hold”) indicated by “cc64” is set to “0” is generated.
[0057]
The MIDI data generated as described above is supplied to the external sound source 200 (x) (or the sound source module 180 in the sound source control device 100) via the MIDI interface 120.
Thereafter, this process ends.
[0058]
Therefore, for example, in the current setup by control change, the volume control effect is assigned to the fader 111 (1), and in this setup state, the volume is set to zero by the user operating the fader 111 (1). After that, a setup change is made by a new control change, and the setup change is made even if a panpot effect is assigned to fader 111 (1) in the new control change. After that, it is possible to output at a desired volume set in the control change corresponding template data 200, instead of the previous volume zero state.
[0059]
On the other hand, as a result of the determination in step S422, if the default value output (Df) is not set, the CPU 130 ends the process as it is.
[0060]
[New processing of CC_old (step S415)]: See FIG.
First, in the control change correspondence template data 200 stored in the RAM 150 (see FIG. 3 above), the CPU 130 sets the new item of the NEW item corresponding to the assignment information (CC_new) after the change of the target fader 111 (n). The content is acquired (step S431), and it is determined whether or not the item content is a default value output (Df) (step S432).
[0061]
If the default value output (Df) is set as a result of the determination in step S432, the CPU 130 acquires the default value set in the value item corresponding to the setting item in the control change correspondence template data 200, MIDI data including a control change for setting the effect indicated by the assignment information (CC_new) to the default value is generated (step S433).
The generated MIDI data is supplied to the external sound source 200 (x) (or the sound source module 180 in the sound source control device 100) via the MIDI interface 120.
Thereafter, this process ends.
[0062]
If the default value output (Df) is not set as a result of the determination in step S432, the CPU 130 determines whether or not the content of the new item is a set value output (Set) (step S434).
[0063]
If the setting value output (Set) is set as a result of the determination in step S434, the CPU 130 acquires the setting value set in the value item corresponding to the setting item in the control change correspondence template data 200, MIDI data including a control change for setting the effect indicated by the assignment information (CC_new) to the set value is generated (step S435).
The generated MIDI data is supplied to the external sound source 200 (x) (or the sound source module 180 in the sound source control device 100) via the MIDI interface 120.
Thereafter, this process ends.
[0064]
On the other hand, if the setting value output (Set) is not set as a result of the determination in step S434, the CPU 130 ends the process as it is.
[0065]
[A / D processing (step S402)]: See FIG.
First, the CPU 130 executes a corresponding process (other processes) as necessary (step S441), and processes from the next step S442 for each of the faders 111 (1) to 111 (8) of the operation panel 110. Repeatedly.
[0066]
That is, CPU 130 determines whether target fader 111 (n) has been operated (whether there has been a change) (step S442).
[0067]
As a result of the determination in step S442, if the target fader 111 (n) has not changed, the CPU 130 does not execute the processes in steps S443 and S444, and performs the steps for all faders 111 (1) to 111 (8). It is determined whether or not the processing of S442 to Step S444 has been completed (Step S445). As a result of this determination, the processing is terminated only when the processing is terminated. Otherwise, the next fader 111 (n + 1) is determined. In order to execute the process, the process returns to step S442 again, and the subsequent process steps are repeatedly executed.
[0068]
As a result of the determination in step S442, if the target fader 111 (n) has changed, the CPU 130 executes a process (MIDI process) for the target fader 111 (n) (step S443), and the corresponding process (step S443). The other process is executed (step S444).
[0069]
Thereafter, the CPU 130 determines whether or not the processing of steps S442 to S444 has been completed for all faders 111 (1) to 111 (8) (step S445). However, in order to execute the process of the next fader 111 (n + 1), the process returns to step S442 again, and the subsequent process steps are repeatedly executed.
[0070]
[MIDI processing for target fader 111 (n) (step S443)]: See FIG.
First, the CPU 130 digitizes the operation amount of the target fader 111 (n), and temporarily stores the digital value in the work area of the RAM 150 (here, “A”) (step S451).
[0071]
Next, the CPU 130 determines whether or not the target fader 111 (n) is of a type (volume type) that takes a volume value such as “0” to “127” (step S452).
As a result of this determination, if the target fader 111 (n) is a volume type, the CPU 130 executes the processing from step S458 described later as it is.
[0072]
If it is determined in step S452 that the target fader 111 (n) is not a volume type, the CPU 130 is of a type that takes a relative value such as “−50” to “0” to “+50” (relative value type). Whether or not (step S453).
[0073]
If it is determined in step S452 that the target fader 111 (n) is a relative value type, the CPU 130 subtracts “64” from the value in the area A temporarily held in step S451, and as a result, the value in the area A is obtained. Is updated (step S457). This is because when the target fader 111 (n) is of the relative value type, the sixth bit of the value (the value in the area A) for the manipulated variable indicates “+” or “−”.
Thereafter, the CPU 130 executes processing from step S458 described later.
[0074]
If it is determined in step S452 that the target fader 111 (n) is not a relative value type, the CPU 130 recognizes that the target fader 111 (n) is of a type that takes an ON / OFF value (switch type), and the target The ON / OFF change of fader 111 (n) is determined (step S454, step S455).
[0075]
Specifically, when the target fader 111 (n) is a switch type, the sixth bit of the value for the operation (the value in the area A) indicates ON / OFF. For this reason, the sixth bit (A_old.6) of the value in the work area A_old of the RAM 150 in which the state of the previous target fader 111 (n) is stored, and the current state of the target fader 111 (n) are stored. The exclusive OR (exclusive) with the 6th bit (A.6) of the value in the area A is taken (step S454), and the ON / OFF change of the target fader 111 (n) is discriminated based on the result. (Step S454, Step S455).
[0076]
As a result of the determination in step S455, when the target fader 111 (n) is ON / OFF changed, the CPU 130 stores the value in the area A for the area A_old (step S456), and processing from S458 described later. Execute.
[0077]
On the other hand, if the result of the determination in step S455 is that there is no ON / OFF change of the target fader 111 (n), the CPU 130 ends this processing as it is.
[0078]
As processing from step S458, the CPU 130 outputs a predetermined command to the tone generator 200 (x) to which the MIDI interface 120 is connected (or the tone generator module 180 of the tone generator control device 100) (step 458). Information (CC #) indicating the effect assigned to the target fader 111 (n) is output (step S459), and a value in area A (a value corresponding to the operation amount) is output (step S460).
Thereafter, the CPU 130 ends the process.
