  The present invention relates to an application program for realizing acoustic processing functions such as recording and reproduction of an acoustic signal, effect application, and mixing.

  2. Description of the Related Art Conventionally, in an acoustic signal processing apparatus using a computer, it is known to perform acoustic processing operations such as recording, editing, and mixing of performance data by digital signal processing. The computer used in the acoustic signal processing device is a general-purpose computer such as a PC (personal computer), and includes various hardware devices such as an audio interface and a MIDI (Musical Instrument Digital Interface) interface necessary for the acoustic signal processing device. Yes. In addition, an application program for executing an acoustic signal processing function is mounted on the computer. As a result, in the computer, acoustic signal processing functions such as recording and reproduction of acoustic signals, effect application, and mixing are realized. Such an acoustic signal processing apparatus is called a digital audio workstation (DAW). An application program that causes a computer to execute the DAW function is referred to as “DAW software” in the following description.

  DAW software that runs on a PC is enriched, and by installing DAW software on a PC, individuals can easily produce music. In addition, the functions of DAW software have increased and the parameters have increased, and it has become difficult to operate all parameters only by operating the mouse. For this reason, a dedicated controller for operating the DAW software is connected to a PC on which the DAW software is installed, and the DAW software is remotely controlled from an external controller. When a controller is connected to a PC on which DAW software is installed, the designated parameters of the channel set on the DAW software (or on the controller) can be remotely controlled.

MC Control User Guide, P.29-49, [online], [Search February 10, 2011], Internet <http://connect.euphonix.com/documents/MC_Control_User_Guide_rC_Jap.pdf> Steinberg Media Technologies GmbH CC121 Operation Manual, [online], [Search February 10, 2011], Internet <ftp://ftp.steinberg.net/Download/Hardware/CC121/CC121_OperationManual_en.pdf>

The dedicated controller for operating the DAW software has many commercial devices and is expensive. There are inexpensive controllers for personal use, but the number of physical controls is small, and it is difficult to operate multiple parameters and multiple tracks simultaneously. Also, since many PCs with DAW software installed are for personal use and other external devices are connected to the PC, the physical connection state of the controller is not always the same. For this reason, there is a problem that the connection state between the DAW software and the controller has to be reset depending on the situation. In addition, many types of controllers are designed on the assumption that one model is used alone, and in the first place, there is a problem that a plurality of controllers cannot be used simultaneously and linked.
Accordingly, an object of the present invention is to provide an application program that does not require resetting the connection state with the application program, and that allows a plurality of external controllers to be connected and used in conjunction with each other.

  In order to achieve the above object, an application program of the present invention is an application program for realizing a mixer function in a computer, and includes a plurality of faders connected to the computer and capable of remotely controlling channel parameters. For the controller device provided, assign the channels mixed by the mixer function to the plurality of faders in ascending order from the first channel, and when the plurality of controller devices are connected to the computer, the plurality of faders The assigning procedure for assigning the channels in ascending order from the first channel to the faders of the number of faders that the entire controller device has, and the controller connected to the computer Each identification information of Ra device, are the most important feature that to execute a storage procedure for storing the controller information including the leading channel number of the total channels assigned in said assignment step.

  According to the present invention, when a plurality of controller devices are connected to a computer, channels are assigned in ascending order from the first channel to the faders corresponding to the number of faders of the plurality of controller devices as a whole. Since controller information including the identification information of each connected controller device and the first channel number of all channels assigned in the assigning procedure is stored, a plurality of controller devices can be connected to When the program is started, the saved controller information can be read to reproduce the previous settings. Further, since the controller information includes identification information of each controller device connected to the computer, it is possible to eliminate the need to reset the connection state with the application program.

FIG. 1 is a diagram showing a configuration in which a controller device is connected to a PC (personal computer) in which an application program according to an embodiment of the present invention is installed.
In FIG. 1, the PC 1 has DAW software which is an application program of an embodiment of the present invention called DAW (Digital Audio Workstation) for realizing sound processing functions such as recording and reproduction of sound signals, effect application and mixing. Installed. Two external remote controllers 2 and an external remote controller 3 which are dedicated controller devices for operating the DAW software are connected to the PC 1. The PC 1 is equipped with a plurality of USB terminals of a USB (Universal Serial Bus) interface, which is one of the serial interface standards for connecting peripheral devices to the PC 1, and the external remote controllers 2 and 3 are also equipped with USB terminals. . The PC 1 and the external remote controllers 2 and 3 are connected so that they can communicate with each other by connecting the respective USB terminals with a USB cable. The external remote controllers 2 and 3 can remotely control the parameters of each channel in the DAW software.

In the example shown in FIG. 1, two external remote controllers 2 and 3 are connected to the PC 1, but up to n external remote controllers (n is, for example, 4) can be connected. . The external remote controllers 2 and 3 have the same configuration, and the configuration will be described below by taking the external remote controller 2 as an example.
As shown in FIG. 1, the external remote controller 2 includes four faders Fd2a, Fd2b, Fd2c, and Fd2d. The four faders Fd2a to Fd2d are vertically long touch panels, and the fader levels of the channels assigned to the faders Fd2a to Fd2d can be adjusted by sliding a finger or the like on the touch panel. Inside the touch panels of the faders Fd2a to Fd2d, display portions Lv2a, Lv2b, Lv2c, and Lv2d each including a plurality of LEDs arranged at substantially equal intervals along the long axis of the touch panel are provided. In the display portions Lv2a to Lv2d, LEDs corresponding to fader picking positions (fader levels) of the assigned channels are turned on. Then, when a finger or the like is slid on the faders Fd2a to Fd2d, the fader picking position is moved, so that the LEDs lit on the display portions Lv2a to Lv2d move in conjunction with the moved fader picking position. Become. In this case, since the position of the fader picking corresponds to the fader level, the fader level can be adjusted by sliding a finger or the like on the faders Fd2a to Fd2d.

Next, FIG. 2 shows an example of a DAW GUI (Graphical User Interface) screen on the PC 1 to which the external remote controllers 2 and 3 are connected and the DAW software is activated as shown in FIG. In the illustrated example, a sequencer window a and a mixer window b are displayed on the GUI screen of the DAW. The window a is a GUI that can produce music, and information on a plurality of tracks of performance data and performance data for each track are displayed in an elongated rectangular shape in time series. When the play button is pressed, the cursor c moves to the right at a speed corresponding to the tempo, and the performance data on each track at the cursor position is played. Also, the DAW software realizes a mixer function, and when reproduced, the acoustic signals of the tracks are mixed and output by the mixer. Window b is the GUI of the mixer that mixes the audio signals of each track. At least faders for multiple channels for adjusting the mixing level of each track are displayed. Drag the fader knob on the screen. By moving the fader, the fader level of the channel (track) assigned to the fader can be adjusted, and the mixed level can be adjusted.
For example, faders for 12 channels are displayed in the window b, and a channel composed of each track displayed in the window a can be assigned to each fader.

  The external remote controller 2 can remotely control the position of the fader pick instead of the fader displayed in the window b. In this case, the positions of the fader knobs of the channels assigned to the four faders Fd2a to Fd2d of the external remote controller 2 are remotely controlled. The faders Fd2a to Fd2d can be assigned any continuous 4 channels in ascending order, and cannot be assigned non-continuous random channels. The assigned four channels can be changed by pressing a channel movement button provided in “Channel” or a bank movement button provided in “Bank”. Here, when the “Channel” button Cd2 (“<”) is pressed, the channels assigned to the faders Fd2a to Fd2d are moved in the direction of decreasing the channel number one by one. For example, when ch3 to ch6 are assigned to faders Fd2a to Fd2d, pressing a button Cd2 ("<") assigns ch2 to ch5 to faders Fd2a to Fd2d. Further, when the “Channel” button Cu2 (“>”) is pressed, the channels assigned to the faders Fd2a to Fd2d are moved in the direction in which the channel number is increased one by one. For example, when ch3 to ch6 are assigned to faders Fd2a to Fd2d, pressing button Cu2 assigns ch4 to ch7 to faders Fd2a to Fd2d. Since the channel numbers displayed in the window b are sequentially increased from the left side to the right side, the button Cd2 (“<”) is a channel left button, and the button Cu2 (“>”) is a channel right button. Become.

Further, when the “Bank” button Bd2 (“<”) is pressed, the channel number assigned to the faders Fd2a to Fd2d moves in the direction of decreasing the channel number for every four channels. For example, when ch6 to ch9 are assigned to faders Fd2a to Fd2d, when button Bd2 is pressed, ch2 to ch5 are assigned to faders Fd2a to Fd2d. Further, when the “Bank” button Bu2 (“>”) is pressed, the channel number is increased in increments of four channels for which one channel is assigned to the faders Fd2a to Fd2d. For example, when ch6 to ch9 are assigned to faders Fd2a to Fd2d, when the button Bu2 is pressed, ch10 to ch13 are assigned to faders Fd2a to Fd2d. That is, the button Bd2 (“<”) is a bank left button, and the button Bu2 (“>”) is a bank right button.
As described above, any continuous four channels can be assigned to the faders Fd2a to Fd2d by pressing the channel moving buttons Cd2 and Cu2 or the bank moving buttons Bd2 and Bu2.

As described above, the faders Fd2a to Fd2d can be assigned four consecutive channels in ascending order independently of the channel selected in the window b of the PC1, but the button Cd2 (“<”) and the button When Sh2 (“Shift”) is pressed, the function of the button Cd2 is changed to “Select”, and four consecutive channels in ascending order starting with the channel currently selected in the window b of the PC 1 are assigned to the faders Fd2a to Fd2d. Each is assigned. For example, when ch3 is selected in window b, ch3 to ch6 are assigned to faders Fd2a to Fd2d. When the button Cu2 (“<”) and the button Sh2 (“Shift”) are pressed, the function of the button Cu2 is changed to “Meter”, and the input level of the channel assigned to the faders Fd2a to Fd2d is changed. It is displayed on each display part Lv2a-Lv2d. When a finger is slid on any of the faders Fd2a to Fd2d while the level meter is displayed by pressing the button Cu2 (“<”) and the button Sh2 (“Shift”), the display portion of the operated fader is displayed for a certain period of time. After displaying the position of the fader knob, the level meter is displayed again. When the external remote controller 2 is activated, the level meter display function is turned off.
The external remote controller 3 also has the same function as the external remote controller 2 described above, and the external remote controllers 2 and 3 perform the same operation.

FIG. 3 is a block diagram showing a hardware configuration of the PC 1 in which DAW software is installed.
As shown in FIG. 3, a CPU (Central Processing Unit) 10 in the PC 1 executes a management program (OS: Operating System), and controls the entire operation of the PC 1 on the OS. The PC 1 includes a nonvolatile ROM (Read Only Member) 11 that stores various programs and various data, and a RAM (Random Access Memory) 12 that stores a work area of the CPU 10 and various data. Further, the PC 1 includes a storage device 21 that is a drive device including various recording media such as a hard disk HD, a compact disk CD, and a flexible disk FD. Various application software such as DAW software executed by the CPU 10 is stored in the hard disk HD. Stored. By executing the DAW software, the CPU 10 realizes an acoustic signal processing function such as recording and reproduction of an acoustic signal, application of an effect, and mixing in the PC 1, and music production can be easily performed using the PC 1. .

  The display IF 13 is a display interface that displays various GUI screens of the active application on the display unit 14 such as a liquid crystal display. The detection IF 15 is an interface that scans the operation element 16 such as a key or a switch provided in the PC 1 and detects an operation on the operation element 16, and outputs an operation instruction signal corresponding to the detected operation element. . The communication IF 17 is a communication interface for communicating with an external device such as a controller device via the communication I / O 18, and is an interface such as USB or Ethernet (registered trademark). The effector (EFX) 19 adds effects such as reverberation, echo, and chorus to the sound signal mixed in the DAW software under the control of the CPU 10. The DSP 20 adjusts and mixes the volume level and frequency characteristics of the input acoustic signal based on the set parameters under the control of the CPU 10, and controls the acoustic characteristics such as volume, pan, and effect based on the parameters. Sound signal processing is performed. The CPU 10, ROM 11, RAM 12, display IF 13, detection IF 15, communication IF 17, EFX 19, DSP 20, and storage device 21 exchange data and the like via the communication bus 22.

The AD 23 is a plurality of analog input ports for inputting analog signals to the PC 1, and the analog input signals input at the AD 23 are converted into digital signals and sent to the audio bus 26. The DA 24 is a plurality of analog output ports for outputting the mixed signal mixed from the PC 1 to the outside. The digital output signal received via the audio bus 26 in the DA 24 is converted into an analog signal and output. The DD 25 is a plurality of digital input / output ports for inputting a digital signal to the PC 1 and outputting a digital signal mixed to the outside. The digital input signal input in the DD 25 is sent to the audio bus 26, and the audio bus The digital output signal received via the H.26 is output to a digital recorder or the like. The EFX 19 and the DSP 20 exchange data with the AD 23, DA 24, and DD 25 via the audio bus 26. The digital signal sent from the AD 23 and DD 25 to the audio bus 26 is received by the DSP 20 and subjected to the digital signal processing described above.
The above-described AD23, DA24, and DD25 may be provided in the PC 1 with hardware, but may be installed in the PC 1 with software. Further, if the CPU 10 executes the acoustic signal processing instead of the DSP 20, the DSP 20 can be omitted.

Next, FIG. 4 shows a hierarchical structure of the PC when the external remote controller is connected to the PC in which the DAW software according to the embodiment of the present invention is installed.
In the case shown in FIG. 4, three external remote controllers 2, 3, 4 are connected to the PC 1. The PC 1 and the external remote controllers 2, 3 and 4 are connected by USB cables attached to the respective USB terminals. The external remote controllers 2, 3, and 4 are connected to ports 1a having different port numbers of the PC 1 under the management of the OS 1c. The port number depends on the driver 1b, and the correspondence relationship between each port number and the external remote controllers 2, 3, and 4 is stored by the OS 1c. Also, the external remote controllers 2, 3, and 4 are logically connected to different port names of the DAW software MIDI ports under the management of the OS 1c. The correspondence between the port name and the external remote controllers 2, 3, and 4 is determined by the DAW software and stored. This enables communication between the DAW software 1d and the external remote controllers 2, 3 and 4 under the management of the OS 1c.
When the external remote controllers 2, 3, and 4 are connected and the DAW software 1d is started for the first time, the external remote controllers 2, 3, and 4 are newly registered in the order of the port names assigned to the MIDI ports. The port name index depends on the driver 1b, but is a serial number such as a MAC (Media Access Control address) address or a serial number of an external remote controller connected to the port. Further, when the DAW software 1d is started for the first time, a controller ID that can uniquely identify each of the external remote controllers 2, 3, and 4 is assigned to each using the port name index. The DAW software manages and stores the properties of the external remote controllers 2, 3, and 4 registered in the DAW software. This property includes the name of the connected port and the assigned controller ID.

Next, FIG. 5 shows a memory image of the controller information of the external remote controller. The controller information is held in the work area of the RAM 12 used by the DAW software.
The controller information includes information on the first channel (ch number) of all channels previously assigned to the external remote controller, and controller A, which is the external remote controller registered in the DAW software in the order of the port name index. The properties of controller B,... Are stored. The properties of controller A, controller B,... Include the port name of the connected MIDI port, the assigned controller ID, the channel number of the first channel among the channels assigned to the external remote controller, The number of faders of the fader provided in the external remote controller is saved. Even if the registered external remote controller is removed, its properties are retained. Further, when the DAW software is stopped, the controller information shown in FIG. 5 is stored in the non-volatile storage device 21. When the DAW software is started, the controller information is read from the storage device 21 and stored in the RAM 12. Will be set.
By using this controller information when the DAW software is started next time, even if the external remote controller is connected to a port name of a MIDI port different from the previous one, as explained below, Channels assigned to can be restored.

A mode of basic channel assignment to the external remote controller 2 is shown in FIG.
When the DAW software according to the present invention is activated, at least the mixer function is realized, and the “Mixer” screen is displayed in the window b as shown in FIG. On this “Mixer” screen, 12 channel faders 30 of 1ch to 12ch, in which the channel numbers are sequentially increased by 1 from the left to the right, are displayed. On the other hand, the external remote controller 2 includes four faders Fd2a to Fd2d, and a channel can be assigned to each of the four faders Fd2a to Fd2d. Here, it is assumed that four channels 3ch to 6ch surrounded by broken lines in the window b are assigned to the faders Fd2a to Fd2d, respectively. In this case, the position of the 3ch fader picking can be remotely controlled by sliding a finger or the like on the fader Fd2a, and the LED lit on the display unit Lv2a moves in conjunction with the moved fader picking position. To come. The same applies to the faders Fd2b, Fd2c, and Fd2d. By sliding a finger or the like on any one of the faders Fd2b, Fd2c, and Fd2d, the position of the 4ch to 6ch fader knobs assigned to the fader can be remotely controlled. Thus, the LEDs lit in the corresponding display portions Lv2b, Lv2c, and Lv2d are moved in conjunction with the moved fader knob position.
When the remote control is performed by sliding a finger or the like on the faders Fd2a to Fd2d of the external remote controller 2, the displayed fader knob 31 of the corresponding channel fader 30 moves in conjunction with the fader.

Next, a detailed mode of assigning a channel to the external remote controller 2 when one external remote controller 2 is connected to the PC 1 will be described with reference to FIG.
In FIG. 7, the DAW software according to the present invention is activated on the PC 1, and 12 channel faders 30 of 1ch to 12ch are displayed on the “mixer” screen of the window b. One external remote controller 2 is connected to the PC 1. Each channel fader 30 has a fader knob 31, a level meter 33, a mute button “m”, and a solo button “s”. Accordingly, the fader level of the assigned channel can be adjusted by dragging and moving the fader knob 31 of the channel fader 30 with the pointing device. Also, the input level of the assigned channel is displayed on the level meter, the mute on / off of that channel is switched by the mute button “m”, and the solo on / off is switched by the solo button “s”. Become. Further, the channel number 32 of the channel fader 30 is shown at the bottom of the channel fader 30. In the “mixer” screen of the window b shown in the figure, the ch3 ch fader 30 whose background is displayed in gray is selected.

  It is assumed that ch3 to ch6 indicated as the current assignment range 40 are assigned to the faders Fd2a to Fd2d in the external remote controller 2. If the channel light button Cu2 (">") of the external remote controller 2 is pressed in the current assignment range 40, the channel moves to the right by one channel, and ch4 to ch7 indicated by the assignment range 41 are faders Fd2a to Assigned to Fd2d. If the bank write button Bu2 (">") is pressed in the state of the assignment range 41, the bank moves to the right by one bank size, and ch8 to ch11 indicated by the assignment range 42 are assigned to the faders Fd2a to Fd2d. It becomes like this. One bank size in this case is set to four channels, which are the number of faders that the external remote controller 2 has, since there is one external remote controller connected to the PC 1.

  If the channel left button Cd2 (“<”) of the external remote controller 2 is pressed in the state of the assignment range 40, it moves to the left by one channel so that ch2 to ch5 are assigned to the faders Fd2a to Fd2d. Become. In addition, if the bank left button Bd2 ("<") is pressed in the state of the assignment range 41, it moves to the left by one bank size, but in this case, only three channels that are less than one bank size are on the left side. Since there is no channel, the channel moves to the left by 3 channels, and the minimum channel 1ch is assigned to the leftmost fader Fd2a, and the subsequent ascending channels 2 to 4 are assigned to the faders Fd2b to Fd2d. Thus, ch1 to ch4 are assigned to faders Fd2a to Fd2d.

Next, referring to FIG. 8, a detailed mode of assigning channels to the external remote controller 2 and the external remote controller 3 when the two external remote controllers 2 and the external remote controller 3 are connected to the PC 1 will be described. explain.
In FIG. 8, the DAW software according to the present invention is activated on the PC 1, and 12 channel faders 30 of 1ch to 12ch are displayed on the “mixer” screen of the window b. Two external remote controllers, an external remote controller 2 and an external remote controller 3, are connected to the PC 1. In this case, one bank size is composed of two external remote controllers connected to the PC 1, so that the total number of faders of the external remote controller 2 and the external remote controller 3 is 8 channels. Is done. In the “mixer” screen of the window b shown in the figure, the ch3 ch fader 30 displayed in gray is selected.

  It is assumed that the range of ch3 to ch10 shown as the current assignment range 45 is assigned to the faders Fd2a to Fd2d and the faders Fd3a to Fd3d in the external remote controller 2 and the external remote controller 3. If the channel light button Cu2 (">") of the external remote controller 2 or the channel light button Cu3 (">") of the external remote controller 3 is pressed in the current assignment range 45 state, the channel moves to the right by one channel. Thus, ch4 to ch11 indicated by the assignment range 46 are assigned to faders Fd2a to Fd2d and faders Fd3a to Fd3d. If the bank write button Bu2 (“>”) or the bank write button Bu3 (“>”) is pressed in the state of the assign range 46, the movement is made to the right by 8 channels which are one bank size. However, since 12ch is the maximum channel and there is only one channel on the right side that is less than one bank size, the channel moves to the right by one channel and the maximum channel 12ch is assigned to the rightmost fader Fd3d. Faders Fd3c to Fd3a and faders Fd2d to Fd2a from the right end in which consecutive descending ch11 to ch5 remain are respectively assigned.

  If the channel left button Cd2 ("<") of the external remote controller 2 or the channel left button Cd3 ("<") of the external remote controller 3 is pressed in the state of the assignment 46, the channel moves to the left by one channel. The range of ch2 to ch9 is assigned to faders Fd2a to Fd2d and faders Fd3a to Fd3d. If the bank left button Bd2 ("<") or the bank left button Bd3 ("<") is pressed in the state of the assignment range 47, the movement moves to the left by 8 channels which are one bank size. However, since 1ch is the minimum channel and there are only 3 channels on the left side that are less than the size of one bank, the channel moves to the left side by 3 channels and 1ch, which is the minimum channel, is assigned to the leftmost fader Fd2a. Faders Fd2b to Fd2d and faders Fd3a to Fd3d from the left end in which successive ascending ch2 to ch8 remain are assigned to the faders.

As mentioned above, when n external remote controllers are connected to PC1, all external remote controllers assigned to all external remote controllers can be operated regardless of the channel move button and bank move button of any external remote controller. The channel moves according to the operated button. However, in the case of an operation instruction to move beyond the minimum channel or the maximum channel, the movement is finished by moving to the minimum channel or the maximum channel, and further movement is prohibited. As described above, when the assignment range cannot be moved by the channel for which the operation is instructed, exception assignment processing is performed in which the movement is finished by moving to the minimum channel or the maximum channel.
Also, when n external remote controllers are connected to PC1 and the external remote controller has m faders, the DAW software regards (n * m) as the number of channels of one bank size. Make assignments. That is, even if n external remote controllers are connected, DAW software assumes that one external remote controller having (n * m) faders is logically connected.

Next, a connection state in which three external remote controllers are connected to the PC 1 is shown in FIG. 9A, and a channel assignment state when the DAW software according to the present invention is started for the first time in the connection state is shown in FIG. Shown in b).
In the connection state shown in FIG. 9A, three external remote controllers are connected to the PC1. In this connection state, when the DAW software is started for the first time (at the first startup), the DAW software determines which external remote controller is connected to which port name of the MIDI port, and the index order of the connected port names A new external remote controller is registered. The port name index is a serial number such as the MAC address or serial number of the external remote controller connected to the port, and the port name index order is (A) (B) (C). When the DAW software is activated for the first time, three external remote controllers are registered in the DAW software in the order of the port names in the order of controller A, controller B, and controller C as shown in FIG. 9B. The index of the port name depends on the driver 1b.

  In addition, a unique controller ID is assigned to each of the three external remote controllers Controller A, Controller B, and Controller C newly registered when the DAW software is started for the first time under the management of the DAW software. As shown in (), the channels are assigned from the first channel in the order of Controller A, Controller B, and Controller C in the order of the port name index. At the first activation, channels in ascending order starting from ch1, which is the first channel among channels handled by the DAW software, are assigned in the order of Controller A, Controller B, and Controller C. In this case, as described above, when three external remote controllers Controller A, Controller B, and Controller C are connected, the DAW software regards (n * m) as the number of channels of one bank size and Make assignments. Here, since each external remote controller has four faders, 12 channels (3 * 4 = 12) of ch1 to ch12 are logically connected to one external remote controller having 12 faders. Assign to Controller A, Controller B, and Controller C.

As a result, ch1 to ch4 are assigned to Controller A, ch5 to ch8 are assigned to Controller B, and ch9 to ch12 are assigned to Controller C. When a fourth external remote controller is connected, it is assumed that a logical external remote controller having 16 faders is connected, and the size of one bank is set to 16 channels. 16 channels of ch16 are assigned. In this case, ch13 to ch16 are assigned to the fourth external remote controller.
The controller information saved when the DAW software is started for the first time is the channel number of the first ch1 among all the channels assigned as the first channel, and the profiles of Controller A, Controller B, and Controller C. The profiles of Controller A, Controller B, and Controller C are the port name, controller ID, ch number of the first channel among the assigned channels, and the number of faders.

Next, FIG. 10 (a) shows the channel assignment state to the external remote controller at the previous end, and FIG. 10 (b) shows the channel assignment state to the external remote controller at the next activation of the DAW software according to the present invention. ).
At the end of the previous time shown in FIG. 10A, three external remote controllers Controller A, Controller B, and Controller C are registered in the DAW software, ch1 to ch4 are assigned to Controller A, and ch5 is assigned to Controller B. The DAW software is terminated in the assigned state in which -ch8 is assigned and ch9-ch12 are assigned to Controller C. When finished, the DAW software saves the controller information described above. When the terminated DAW software is activated again (at the next activation), the DAW software recognizes the controller ID from the serial number such as the MAC address or manufacturing number of the external remote controller that is determined to be connected. In the case illustrated in FIG. 10B, controller IDs of Controller A, Controller B, and Controller C are recognized. Then, the stored controller information is read out, and based on the controller ID recognized at the next start-up, it is determined whether the connected external remote controller is registered and whether the configuration is the same as at the previous end. In the case shown in Fig. 10 (b), since Controller A, Controller B, and Controller C are connected to the DAW software, the connected external remote controller is registered, and the configuration is the same as at the end of the previous time. To be judged. As described above, the DAW software assigns channels by regarding 12 channels as the number of channels of one bank size. Here, since the first channel in the controller information is the channel number of ch1, Controller A, Controller is considered that 12 channels of ch1 to ch12 are logically one external remote controller having 12 faders. Assign to B, Controller C. As a result, as shown in FIG. 10B, ch1 to ch4 are assigned to Controller A, ch5 to ch8 are assigned to Controller B, and ch9 to ch12 are assigned to Controller C. Will be restored.

  The DAW software determines whether or not the external remote controller was connected at the previous end based on the controller ID of the external remote controller connected instead of the port name at the next startup. Therefore, it is possible to correctly determine whether the connected external remote controller is registered even if the port name to which the external remote controller is connected is different at the next startup. Also, if the fourth external remote controller is connected at the end of the previous session and ch13 to ch16 are assigned, and it is determined that the same fourth external remote controller is connected at the next startup, The channels 13 to 16 are assigned to the fourth external remote controller, and the assigned state at the end of the previous operation is restored.

Next, FIG. 11A shows the channel assignment state to the external remote controller at the end of the previous time, and the external remote controller when the number of external remote controllers connected at the next activation of the DAW software according to the present invention decreases. FIG. 11B shows the assignment state of the channels to the.
At the end of the previous time shown in FIG. 11A, three external remote controllers Controller A, Controller B, and Controller C are registered in the DAW software, ch1 to ch4 are assigned to Controller A, and ch5 is assigned to Controller B. The DAW software is terminated in the assigned state in which -ch8 is assigned and ch9-ch12 are assigned to Controller C. When finished, the DAW software saves the controller information described above. When the terminated DAW software is activated again (at the next activation), the DAW software recognizes the controller ID from the serial number such as the MAC address or manufacturing number of the external remote controller that is determined to be connected. In the case shown in FIG. 11B, two controller IDs, Controller A and Controller C, are recognized. Then, the stored controller information is read out, and based on the controller ID recognized at the next start-up, it is determined whether the connected external remote controller is registered and whether the configuration is the same as at the previous end.

In the case shown in Fig. 11 (b), Controller A and Controller C are connected to DAW software, but Controller B is not connected, so the connected external remote controller is registered, but in its configuration It is determined that it is different from the previous time when Controller B is not connected. In this case, as described above, since only two external remote controllers are connected to the DAW software, channel assignment is performed considering 8 channels as the number of channels of one bank size. Here, since the first channel in the controller information is the channel number of ch1, Controller A and Controller are regarded as one external remote controller having eight faders logically. Assign to C. As a result, as shown in FIG. 11B, ch1 to ch4 are assigned to Controller A, and ch5 to ch8 are assigned to Controller C and assigned. The DAW software stores controller information reflecting the changed assignment state.
The DAW software determines whether or not the external remote controller was connected at the previous end based on the controller ID of the external remote controller connected instead of the port name at the next startup. Therefore, it is possible to correctly determine whether the connected external remote controller is registered even if the port name to which the external remote controller is connected is different at the next startup. If the fourth external remote controller is connected at the end of the previous session and ch13 to ch16 are assigned, and the same third and fourth external remote controllers are connected at the next startup Ch9 to ch12 are assigned to the third external remote controller, and ch13 to ch16 are assigned to the fourth external remote controller.

Next, FIG. 12A shows the channel assignment state to the external remote controller at the end of the previous time, and the external remote controller when the number of external remote controllers connected at the next activation of the DAW software according to the present invention increases. FIG. 12B shows the assignment state of the channels to the.
At the end of the previous time shown in FIG. 12A, three external remote controllers Controller A, Controller B, and Controller C are registered in the DAW software, ch1 to ch4 are assigned to Controller A, and ch5 is assigned to Controller B. The DAW software is terminated in the assigned state in which -ch8 is assigned and ch9-ch12 are assigned to Controller C. When finished, the DAW software saves the controller information described above. When the terminated DAW software is activated again (at the next activation), the DAW software recognizes the controller ID from the serial number such as the MAC address or manufacturing number of the external remote controller that is determined to be connected. In the case shown in FIG. 12B, the controller IDs of the three Controller A, Controller B, and Controller C are recognized, but the fourth new external remote controller (Controller D) is not registered. The controller ID is not recognized. Then, the stored controller information is read out, and based on the controller ID recognized at the next start-up, it is determined whether the connected external remote controller is registered and whether the configuration is the same as at the previous end.

In the case shown in Fig. 12 (b), it is judged that Controller A, Controller B, and Controller C connected to DAW software are registered, but the fourth new external remote controller (Controller D) is registered. In the configuration, the fourth new external remote controller (Controller D) is connected, and the configuration in which the external remote controller is connected is determined to be different from the previous end. In this case, the DAW software creates controller information including the controller ID of the fourth newly connected external remote controller (Controller D), and newly registers Controller D in the order following Controller C. Next, as described above, since four external remote controllers are connected to the DAW software, channel assignment is performed by regarding 16 channels as the number of channels of one bank size. Here, since the first channel in the controller information is the channel number of ch1, the 16 channels of ch1 to ch16 are logically regarded as one external remote controller having 16 faders. Controller A, Controller Assign to B, Controller C, Controller D. Channel assignments are preferentially assigned to existing registered external remote controllers. As a result, as shown in FIG. 12B, ch1 to ch4 are assigned to Controller A, ch5 to ch8 are assigned to Controller B, ch9 to ch12 are assigned to Controller C, and newly registered Controller D Ch13 to ch16 are assigned to. The DAW software stores controller information reflecting the changed assignment state.
The DAW software determines whether or not the external remote controller was connected at the previous end based on the controller ID of the external remote controller connected instead of the port name at the next startup. Therefore, it is possible to correctly determine whether the connected external remote controller is registered even if the port name to which the external remote controller is connected is different at the next startup. Also, if the fourth external remote controller is connected at the end of the previous session and ch13 to ch16 are assigned, and the same fourth external remote controller is connected at the next startup, the fourth The channels 13 to 16 are assigned to the external remote controller, and the assigned state at the previous end is restored.

Next, FIG. 13A shows the channel assignment state to the external remote controller at the time of the previous end, and when the DAW software according to the present invention is next started up when an external remote controller different from the previous end is connected. FIG. 13B shows the channel assignment state to the external remote controller.
At the end of the previous time shown in FIG. 13A, three external remote controllers Controller A, Controller B, and Controller C are registered in the DAW software, ch1 to ch4 are assigned to Controller A, and ch5 is assigned to Controller B. The DAW software is terminated in the assigned state in which -ch8 is assigned and ch9-ch12 are assigned to Controller C. When finished, the DAW software saves the controller information described above. When the terminated DAW software is activated again (at the next activation), the DAW software recognizes the controller ID from the serial number such as the MAC address or manufacturing number of the external remote controller that is determined to be connected. In the case shown in FIG. 13B, the controller ID of one Controller C is recognized, but the second and third new external remote controllers (Controller D, Controller F) are not registered. The controller ID is not recognized. Then, the stored controller information is read out, and based on the controller ID recognized at the next start-up, it is determined whether the connected external remote controller is registered and whether the configuration is the same as at the previous end.

In the case shown in FIG. 13B, it is determined that Controller C connected to the DAW software is registered, but the second and third new external remote controllers (Controller D, Controller F) are registered. It is determined that the external remote controller (Controller D, Controller F) is connected in the configuration, and the configuration in which the external remote controller is connected is determined to be different from the previous end. In this case, the DAW software creates controller information including the controller ID of the second and third external remote controllers (Controller D, Controller F) that are newly connected, and newly registers them in the order of Controller D, Controller F. To do. Next, since the DAW software has three external remote controllers connected as described above, channel assignment is performed by regarding 12 channels as the number of channels of one bank size. Here, since the first channel in the controller information is the channel number of ch1, Controller C and Controller are regarded as one external remote controller having twelve faders logically. Assign to D, Controller F. Channel assignments are preferentially assigned to existing registered external remote controllers. As a result, as shown in FIG. 13B, ch1 to ch4 are assigned to Controller C, ch5 to ch8 are assigned to newly registered Controller D, and ch9 to ch12 are assigned to Controller F. The DAW software stores controller information reflecting the changed assignment state. Further, when the fourth new external remote controller is connected at the next startup, ch13 to ch16 are assigned to the fourth external remote controller.
The DAW software determines whether or not the external remote controller was connected at the previous end based on the controller ID of the external remote controller connected instead of the port name at the next startup. Therefore, it is possible to correctly determine whether the connected external remote controller is registered even if the port name to which the external remote controller is connected is different at the next startup.

In the application program of the present invention described above, the controller information indicating the channel assignment state to the controller device at the end of the previous time is automatically saved, and the channel to the controller device is based on the controller information saved at the next startup. Therefore, seamless connection with the application program can be made possible without requiring the user to save and restore the connection state and setting state of the controller device. For this reason, if the controller device is physically connected, the controller device can be used in the state when the DAW software according to the present invention was previously terminated. In this case, even when the number of connected controller devices is different from the previous end of the DAW software according to the present invention, the assigned first channel is the same, and when the number of connected devices decreases, the assigned channel is packed, When the number of connected devices increases, the assigned channel is expanded. Further, it is possible to eliminate the need to reset the logical connection state according to the physical connection state.
In the above description, the controller device is limited to the fader unit. However, the controller device is not limited to this, and the controller device remotely controls the parameters of the acoustic signal processing function such as recording and playback of the acoustic signal, effect addition, and mixing. It is good. In addition, although the controller device is connected to the computer via USB, the physical connection method is not limited to USB, and connection may be made using another communication interface.
