Description

  The present invention relates to a mixer configuration editing apparatus that creates and edits a mixer configuration of a digital mixer that processes an acoustic signal, and more particularly to a mixer configuration editing apparatus that can easily set whether or not a component is to be compiled.

  Conventionally, a digital mixer capable of custom-made mixer configuration is known. This is a mixer configuration (signal processing) in which an acoustic signal processing unit is configured using a processor (for example, a digital signal processing device (DSP)) operable according to a program, and is created and edited using an external PC (personal computer). The acoustic signal can be processed based on the configuration. Creation and editing of the mixer configuration on the PC is performed by a dedicated mixer control program (for example, see Non-Patent Document 1 below). In other words, the mixer control program is executed on the PC to display the mixer configuration screen, components that are signal processing components are arranged on the screen, and the terminals of the arranged components are connected to each other by connecting the terminals. Specify and create and edit mixer configurations. The created mixer configuration is compiled (converted into information that can be interpreted by the digital mixer), then transferred from the PC to the digital mixer (mixing engine) and executed, so that the digital mixer realizes the operation of the mixer configuration. .

FIG. 7 shows an example of a conventional mixer configuration screen. By executing the mixer control program on the PC, the mixer configuration screen 700 is displayed on the PC display. Reference numeral 702 denotes a configuration window, in which components are arranged and connected to create a mixer configuration. Reference numeral 701 denotes a toolkit window, and a list of components as parts to be arranged by drag and drop is displayed in the configuration window 702. For example, components include a matrix mixer with various numbers of inputs and outputs, an EQ (equalizer), a delay (delay circuit), and the like. When the mixer configuration is created on the configuration window 702, it is stored in a file, and compiled and transferred to the digital mixer by a predetermined operation. In the digital mixer, the operation of the mixer configuration is realized by executing the transferred mixer configuration.
"DME Designer Version 1.1 Instruction Manual", Yamaha Corporation, 2004, Chapter 4 etc.

  As described above, when creating and editing a mixer configuration on the mixer configuration screen, the target component is placed on the screen and connected accurately to other components, so that it is assumed that the component will be used, and the target of compilation It is said. In order to remove it from the compilation target, it must be deleted from the screen or reconnected to a connection that does not involve the relevant component.

  However, it is very troublesome to release / reset the connection connected to the component in order to simply remove / return it from the compilation target. Also, if you delete a component for which some parameter values have already been customized, it is necessary to reproduce the previous settings when rearranged, which is also very troublesome. In particular, the digital mixer (mixer engine) resources (usable memory capacity, etc.) that can be operated with the created mixer configuration are limited, and designers can replace components, change connections, Since a desired mixer configuration is often designed by changing component parameters, it has been extremely complicated to reset parameters by rearranging components as described above.

  It is an object of the present invention to enable a mixer configuration editing apparatus for creating and editing a mixer configuration to switch between valid / invalid of a component on a mixer configuration screen and easily set whether to compile. And

  In order to achieve the above object, according to the present invention, a component that performs signal processing is arranged on a mixer configuration screen, and the input / output relationship is defined by connecting the terminals of the arranged components with a wire, and the mixer configuration is defined. In the mixer configuration editing device to be created and edited, for each component placed on the mixer configuration screen, accepts a specification as to whether or not to compile with the component remaining on the mixer configuration screen, and based on the specification Information about whether or not to compile is stored as property information of the component. When compiling is instructed, the property information of each component is referred to in the pre-processing, and the component data corresponding to that component is deleted for the component designated not to be compiled, and the compiling processing is performed. hand over.

  For a component designated not to be compiled, (1) delete the connection connected to the input terminal of the component and the connection connected to the output terminal and pass it to the compilation process, Or (2) further comprising means for accepting a designation as to whether the connection connected to the input terminal of the component and the connection connected to the output terminal are connected to the compiling process; Based on this designation, it is preferable to compile after correcting the connection data as shown in (1) or (2) for each component. In this case, if the number of input terminals and the number of output terminals of the component match, the specification of (1) or (2) is accepted. It is good. Furthermore, components designated not to be compiled may be displayed on the mixer configuration screen in a display mode different from the components to be compiled.

  According to the present invention, in a mixer configuration editing apparatus for creating and editing a mixer configuration, it is possible to easily set whether to compile or not by switching the validity / invalidity of a component on the mixer configuration screen. In addition, since it is not necessary to redo the connection and parameter value setting, the labor for design change and resource check is greatly reduced.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 shows the configuration of an engine of a digital mixer according to an embodiment of the present invention. The engine 100 includes a central processing unit (CPU) 101, a flash memory 102, a RAM (random access memory) 103, a PC input / output interface (I / O) 104, a MIDI I / O 105, other I / Os 106, and a display. 107, an operator 108, a waveform I / O 109, a signal processing unit (DSP group) 110, and a system bus 120.

  A central processing unit (CPU) 101 is a processing device that controls the operation of the entire mixer. The flash memory 102 is a nonvolatile memory that stores various programs and data used by the CPU 101 and the DSP of the signal processing unit 110. The RAM 103 is a volatile memory used for a load area and a work area for programs executed by the CPU 101. The PC I / O 104 is an interface (for example, LAN, USB, serial I / O, etc.) for connecting an external personal computer (PC) 130. The PC 130 is a general-purpose PC including a keyboard, a display, a mouse, and the like. The MIDI I / O 105 is an interface for connecting various MIDI devices. The other I / O 106 is an interface for connecting other devices. The display 107 is a display for displaying various information provided on the external panel of the mixer. The operator 108 is various operators that are provided on the external panel and are operated by the user. The waveform I / O 109 is an interface for exchanging acoustic signals with an external device. For example, an analog acoustic signal is input, converted into a digital signal, and passed to the signal processing unit 110 (A / D (analog). -Digital) conversion function, a digital signal input function for inputting a digital acoustic signal and passing it to the signal processing unit 110, and a digital acoustic signal output from the signal processing unit 110 for converting to an analog acoustic signal for a sound system Realizes output D / A (digital / analog) conversion function. The signal processing unit 110 includes several DSPs (digital signal processors). These DSPs execute various microprograms based on instructions from the CPU 101 to perform mixing processing, effect applying processing, volume level control processing, and the like of the waveform signal input via the waveform I / O 109. Are output via the waveform I / O 109.

  In the engine 100 of this digital mixer, the mixer configuration realized by the signal processing unit 110 can be custom-made. The mixer configuration can be created and edited on the screen of the PC 130 by a predetermined mixer control program 131 operating on the PC 130. A collection of multiple created mixer configurations is called a configuration. The mixer control program 131 generates a configuration as configuration data 132 on the memory in response to an operation instruction on the user's screen. The configuration data 132 can be saved as a file in any storage device writable from the PC 130. Each mixer configuration (CF data described later) of configuration data on a storage device such as a memory or a hard disk on the PC 130 side can be transferred to the engine 100 after being compiled. The engine 100 can store and save the configuration data transferred from the PC 130 in the flash memory 102. By designating one mixer configuration in the configuration data stored in the flash memory 102 as a current by a predetermined operation, the engine 100 operates on the basis of the mixer configuration. Realize.

  FIG. 2A shows the configuration of P (preset) component data (PC data) used by the mixer control program 131 of the PC 130. A P component (hereinafter simply referred to as a component) is a block (signal processing module) that is a basic unit part when customizing a mixer configuration. For example, a matrix mixer (without delay), a matrix mixer with delay, and a compressor Audio components such as effects, crossovers, and individual part components such as faders, switches, pans, and meters are available. As described above, the creation / editing of the mixer configuration by the mixer control program 131 is performed by arranging and connecting these components on the mixer configuration screen of the PC 130. This is equivalent to defining the input / output relationship of the signal. The PC data shown in FIG. 2 (a) is definition data that defines a component, and is stored in advance in any storage means that can be accessed by the mixer control program 131 (in RAM when called for use on the mixer configuration screen). Has been. PC data is prepared for each type of component.

  One piece of PC data includes a PC header, PC configuration information, a PC processing routine, and a display editing processing routine. The PC header includes a component ID (PC_ID) and a component version (PC_Ver). PC data can be specified by PC_ID and PC_Ver. The PC configuration information is data indicating the detailed configuration of the component. The PC processing routine is a program for performing various processes related to PC configuration information. When the mixer control program 131 processes the mixer configuration, a PC processing routine for each component is used. The display editing process routine is a program group used when creating and editing CF data.

  FIG. 2B shows the structure of the configuration data 132 on the RAM processed by the mixer control program 131 in the PC 130. The configuration data 132 includes a plurality of CF data 1 to Ncf and a scene memory. The entire configuration data can be stored as one file in an arbitrary storage device (for example, a hard disk in a PC). Conversely, the configuration data read from an arbitrary storage device is developed and used in the format of FIG. In the CF data 1 to Ncf, the numbers 1 to Ncf are called configuration numbers (CF numbers). CF data (or an area in which the CF data is stored) can be specified by the config number. The current pointer is a pointer that points to the CF data to be processed. The CF data pointed to by the current pointer is displayed on the mixer configuration screen described later with reference to FIG. The CF data pointed to by the current pointer is called “current configuration”.

  One CF data is data defining one mixer configuration, and includes a CF header, PC CAD data, and Nps parameter sets. The CF header includes a configuration ID (CF_ID), a configuration version (CF_Ver), a system version (SYS_Ver), and the like. CF data can be specified by CF_ID and CF_Ver. The CAD data for PC is data that defines what component is connected and how the mixer configuration of the CF data is configured, and is data that specifies a component to be used as a component of the mixer configuration. It consists of some C data and connection data connecting those components. The CAD data for PC also includes display data such as a mixer configuration screen shown in FIG. The C data in the CAD data for PC includes a component ID (C_ID), a component version (C_Ver), a unique ID (U_ID), and other data (for example, a property) that specify a component. As C_ID and C_Ver of the C data, the PC_ID and PC_Ver of the PC data in FIG. Parameter sets 1 to Nps are specific parameter value set data used in each component of the mixer configuration of the CF data.

  FIG. 3 shows an example of a mixer configuration screen (CAD screen) for creating and editing a mixer configuration on the PC 130. The user can create a desired mixer configuration by arranging various components on the screen 300 and connecting the components with wires. A toolkit window 303 displays a list of components. These components correspond to the respective PC data described with reference to FIG. Reference numeral 301 denotes a configuration window in which components are arranged by drag and drop from the toolkit window 303 and connected to create a mixer configuration. The mixer configuration of the configuration window created in this way corresponds to one CF data (current configuration) pointed to by the current pointer in FIG. Specifically, one component arranged on the screen corresponds to one C data of CF data. The connection drawn on the screen is stored as connection data in the CF data. The parameter value set for each component is stored as a parameter set. Reference numerals 311 and 312 are examples of arranged components. Connections have already been made to the input / output terminals of these components.

  After creating and editing a mixer configuration on such a mixer configuration screen, when compiling and transferring are instructed by a predetermined operation, the mixer configuration (CF data of the current configuration) is compiled and converted into data that can be interpreted by the mixer engine 100. To the mixer engine 100. In the engine 100, the CPU 101 generates a microprogram that realizes the mixer configuration based on the transferred compiled CF data, and transfers the microprogram to the signal processing unit 110. The DSP group of the signal processing unit 110 executes the transferred microprogram, whereby the signal processing unit 110 realizes the operation in the mixer configuration of the current configuration.

  As described in the section of the problem to be solved by the invention, the mixer configuration designer deletes and rearranges various components (for example, 311 and 312) on the mixer configuration screen as shown in FIG. Thus, a desired mixer configuration is created. In the present embodiment, even a component that has already been connected on the mixer configuration screen and has been set with parameters can be removed from the compilation target or returned to the original state with a simple operation. 3 indicates a property setting window displayed when an arbitrary component on the screen is right-clicked. With this property setting window, it is possible to specify whether or not the component is to be compiled. In this property setting window 302, only a part of the property setting items (portion related to the present invention) is shown, but actually another property setting item is displayed.

  FIG. 4A shows a property setting screen 401 for components having the same number of inputs and outputs. For example, since the component 311 in FIG. 3 has two input terminals and two output terminals, the property setting screen 401 is displayed when the component 311 is right-clicked. Compile Mode 411 is an item that alternatively designates whether or not the component is to be compiled. When Checking Enable, it means “target”, and when Checking Disable, it means “not target”. In the initial state immediately after the component is placed on the screen, the Enable is checked. Signal Mode 412 is an effective selection item only when Disable is checked. When Enable is checked, Signal Mode 412 is grayed out and cannot be set. When Disable is checked, either Cut or Through of Signal Mode 412 can be alternatively specified. When Cut is checked, at the time of compiling, the input terminal connection and the output terminal connection of the component are compiled in a state in which both are deleted (the connection is considered to have been disconnected). If you check Through, the component itself is deleted when compiling, but the connection connected to the input terminal of the component and the connection connected to the output terminal are connected as they are (the component Is compiled in a bypassed state). Since the number of inputs and outputs is the same, the connection connected to the input terminal and the connection connected to the output terminal can be connected on a one-to-one basis. As the connection method, it is only necessary to connect the same input terminal number and output terminal number. As an attribute of a component, it may be possible to set which input is connected to which output in the case of Through. The setting on the property setting screen 401 is valid when the OK button is pressed, and is canceled when the cancel button is pressed.

  FIG. 4B shows a property setting screen 402 for components having different numbers of inputs and outputs. For example, since the component 312 in FIG. 3 has four input terminals and eight output terminals, the property setting screen 402 is displayed when the component 312 is right-clicked. On the property setting screen 402, Compile Mode 421 is the same setting item as Compile Mode 411 in FIG. When Enable is checked, Signal Mode 422 is grayed out and cannot be set. When Disable is checked, the Signal Mode 422 is forcibly set to Cut and grayed out and cannot be changed. This is because the number of input terminals and the number of output terminals are different, and it is difficult to determine which input is connected to which output when an attempt is made to connect an input and an output through.

  The setting state such as Enable set in FIGS. 4A and 4B is stored as property data in the C data corresponding to each component in FIG. In addition, a component for which Disable is specified is displayed in a display form that can be distinguished from an enabled component on the mixer configuration screen of FIG. For example, display in gray or change color. Here, the ones with different numbers of inputs and outputs are forcibly cut, but it is also possible to select Through / Cut according to the type of component.

  FIG. 4C shows a display example 403 of the resource meter. The resource meter is always displayed when the mixer configuration is created and edited on the mixer configuration screen of FIG. The maximum value of the meter indicates the amount of resources that can be used by the connected mixer engine 100, and the amount of resources used in the mixer configuration on the current mixer configuration screen is displayed in meter display and% display. Of course, the resource of the component for which Disable is set is not counted.

  FIG. 5 shows a processing procedure for analyzing the mixer configuration (CF data of the current configuration) created by the user. This process is executed as a pre-process when compilation is instructed. In step 501, the first component of the CF data is set as a check target, and its Enable check (FIG. 6) is performed.

  FIG. 6 shows the processing procedure of Enable check. In step 601, the Enable state (Compile Mode setting state described in FIG. 4) of the component to be checked is acquired, and in step 602, it is determined whether it is Enable or Disable. When it is Enable, it returns as it is. When it is Disable, in Step 603, the setting of Signal Mode is determined. In the case of Through, in step 604, the C data corresponding to the target component set to Disable is deleted, and the connection data in the CF data is the connection data in which the input terminal and the output terminal of the target component are directly connected. Overwrite and return. When Signal Mode is Cut, in step 605, the C data corresponding to the target component set to Disable is deleted, and the connection data is overwritten with the data from which the connection connected to the target component is deleted. To do. In steps 604 and 605, “deletion of C data” and “overwriting of connection data” have been described. This is because CF data obtained by copying the CF data onto the work memory is deleted as a processing target as pre-processing of compilation. Or overwriting. Since the CF data itself in the original configuration data in FIG. 2 is not rewritten, the CF data can be reused.

  Returning to FIG. 5, after step 501, it is determined in step 502 whether all the input terminals of the component to be checked have been checked. If there is an unchecked input terminal, in step 503, the input terminal is selected. Determine if it is connected to the component output terminal. If not connected, the check target is moved to the next terminal in step 506 and the process returns to step 502. If it is connected, it is checked in steps 504 and 505 that the connected output terminal is one and another component. If so, the process proceeds to step 506. The process proceeds from step 504 to step 507. The processing in steps 502 to 506 is to check whether the output terminal is connected to the input terminal of the component to be checked in a normal state. Note that the check in steps 502 to 506 is an example, and for example, input from a plurality of output terminals to one input terminal may be permitted.

  After checking all input terminals of the components to be checked in step 502, it is determined in step 508 whether all components have been checked. If all the components have been checked, the pre-compilation process is analyzed in step 510 and processed. Finish (after this, proceed to compilation). If there is an unchecked component, the check target is moved to the next component in step 509, the Enable check in FIG. 6 is performed, and the process returns to step 502.

  With the above processing, the Enable component is compiled using the connection of the CF data as it is, and the Disable component is rewritten in steps 604 and 605, and is compiled with the setting not to compile the component in the mixer configuration. The At this time, the method of rewriting the connection can also be set in Signal Mode. These settings can be performed by a simple operation while viewing the resource meter as described with reference to FIG. Further, since the parameter values set for each component remain as parameter set data, the set parameter values can be used regardless of the Enable / Disable setting of the component.
