Description

  The present invention relates to a setting technique related to input / output of a mixer, and in particular, a venue having a special property that the number and arrangement of input devices are changed depending on event contents, but the number and arrangement of output devices are hardly changed. The present invention relates to a suitable mixer technology.

  Conventionally, acoustic signals from various acoustic signal sources such as a microphone are input, mixing processing, effect imparting processing, volume level control processing, etc. are performed, and the processed acoustic signals are output to various output devices such as amplifiers and speakers. There is known a mixer device that outputs to the output. The mixer device includes an analog mixer that performs internal signal processing by analog processing and a digital mixer that performs digital processing. Both analog mixers and digital mixers are input ports for inputting acoustic signals, input controllers with controls for adjusting input signal levels, output ports for outputting output signals after processing such as mixing, and output A large number of output controllers each including an operator for performing signal level adjustment and the like are provided.

  Non-Patent Document 1 is an instruction manual for an analog mixer. Normally, in an analog mixer, a port and a controller are fixed in a one-to-one correspondence. For example, if it is desired to adjust the level of a signal input from a certain input port, a controller for level adjustment corresponding to the input port is provided on the panel. In this way, the port and the controller correspond one-on-one, which is easy for the user to understand. However, as the number of ports increases, the number of controllers on the panel increases, so that the panel surface increases and the size of one controller decreases, making it difficult for the user to use.

  Non-Patent Document 2 is an instruction manual for a digital mixer. Since the digital mixer processes input / output of a large number of ports, the assignment of ports and controllers can be changed. That is, a certain number of controllers are provided on the panel, and operations can be performed while switching assignment of ports and controllers with a changeover switch or the like. Thereby, even if the number of ports increases, there is no inconvenience such as an increase in the panel surface. By assigning a port group to be operated frequently to a controller group at a place where it is easy to operate, an arrangement that allows easy operation by the user can be created.

  Specifically, the above-described assignment change between the port and the controller is realized by a patch function. A patch is an assignment (correspondence relationship) between a port and an internal channel (ch) of the mixer. In the digital mixer, an input patch that assigns an input port and an input channel is provided on the input side, and an output patch that assigns an output port and an output channel is provided on the output side. Since an input channel and an output channel are provided with a controller corresponding to each channel (for example, when the number of channels is large, for example, when the first layer is selected, the first to eighth channels are changed to the first to eighth channels. It is possible to operate by assigning to the eighth controller, and when the second layer is selected, the ninth to sixteenth channels are assigned to the first to eighth controllers for operation, and so on. In some cases, the operation is performed while switching a part), and if a port and ch are assigned by a patch, a signal of a certain port can be adjusted by a controller corresponding to the ch assigned to that port.

  Furthermore, some digital mixers have insert-out and insert-in functions. This is a function of taking out a signal from the middle of the signal path through the output port (insert out) or inputting a signal through the input port in the middle of the signal path (insert in). There are cases where insert-out and insert-in are performed on the signal path of the input channel and insert-out and insert-in are performed on the signal path of the output channel. The former is called an input part insert, and the latter is called an output part insert. The function of such an insert is such that, for example, a signal is extracted from the middle of a signal path of a certain channel, an effect is applied using an external effect device, and the signal is returned to the middle of the signal path of an arbitrary channel again. It is what is used in.

  In the insert function described above, an output port and an input port are used for signal output and input in the middle of the signal path. Therefore, in the input unit, it is necessary to assign which input port is used to extract a signal from which input port and which output port is used to input a signal from which input port to which input channel. This assignment is called an input section insert patch. Similarly, in the output unit, it is necessary to assign which output port is used to take out a signal from which output channel is inserted, and which input port is used to input a signal from which output channel is inserted into which output channel. . This assignment is called an output part insert patch.

  In summary, there are four types of patches: an input patch, an input section insert patch, an output patch, and an output section insert patch. Some analog mixers have an insert function.

  Next, scene data recording (store) and recall (recall), which are functions of the digital mixer, will be described. Digital mixers are used, for example, in concert halls and theaters. During the performance of concerts and plays, you may want to change several parameters at the same time to switch the acoustic environment according to the scene. In particular, quick changes are required during the performance of concerts and plays. Therefore, in the digital mixer, one setting state composed of a plurality of parameters is recorded as one scene data, and the setting state can be changed (a plurality of parameters can be collectively changed) by calling the scene data. With the scene data, it is possible to quickly change the setting state of the mixer.

The number and arrangement of input devices and output devices differ depending on the concert or theatrical work (that is, the number and arrangement of input devices and output devices connected to the input and output ports of the mixer differ), and each piece in the work The usage mode of the input device and the output device is different for each scene. Therefore, it is necessary to record all the patches described above (all assignments of the input unit and the output unit) in the scene data.

  By the way, in recent years, mixer apparatuses are used not only in venues for concerts and plays but also in various places. Some venues, such as churches, have special characteristics that the number and arrangement of input devices are changed depending on the event content, but the number and arrangement of output devices are hardly changed. Even in a mixer apparatus used in such a venue, there is a case where the number and arrangement of input devices may be switched in accordance with scene switching, so that allocation of input ports and input controllers (input patches) can be changed by scene data. Good. However, since the environment on the output side hardly changes, it is hardly desired to change the allocation of the output unit with the scene data. However, if the output patch cannot be changed at all, it will not be possible to deal with cases such as when speakers are rearranged or replaced, or when an additional speaker is temporarily connected. The functionality to change should remain.

  The scene data described above includes all patches in the input and output sections. However, if the environment on the output side is almost unchanged, the patches in the output section are rarely changed by switching the scene. There is almost no need to include a patch. That is, only the input patch and the input part insert patch may be recorded in the scene data, and the output patch and the output part insert patch may not be recorded. However, the input section insert patch is recorded in the scene data, and the assignment of the output port may be changed by this input section insert patch. In this case, the assignment of the output unit that is desired to be fixed is changed. For example, even if a certain output port is fixed and connected to one speaker, if an insert-out from a certain input channel is assigned to the output port by the input section insert patch of the called scene data The allocation of the output port is changed by calling the scene data. This may be an unintended operation for the user.

  The present invention operates the patch function and the scene data recording / calling function unintended by the user even when installed in a venue with special characteristics such that the number and arrangement of output devices are hardly changed. An object of the present invention is to provide a mixer device that can be realized without any problem.

  In order to achieve this object, the present invention includes an input patch for assigning a plurality of input ports and a plurality of input channels, and an output patch for assigning a plurality of output ports and a plurality of output channels. In a mixer having an insert function for inputting / outputting signals to / from an insert point in a signal path and a scene function for storing and recalling mixer settings as scene data, the scene data includes an input patch or an input section insert patch. Is included, but output patch allocation instruction information is not included. Also, when reading of scene data is instructed, it is determined whether or not the scene data includes information defining the assignment of the input part insert patch. If included, the assignment instruction is given by the input part insert patch. An output port is detected, and if the output port is not currently in use, the assigned allocation is executed for the output port.

  In this case, if the scene data contains information that defines the assignment of the input section insert patch, and it is detected that the output port designated by the input section insert patch is already in use, that fact is indicated. A message should be output. Also, if the scene data contains information that defines the assignment of the input section insert patch, and if it is detected that the output port assigned by the input section insert patch is already in use, an empty output port If there is an empty output port, the instructed assignment is executed, and if there is no empty output port, the instructed assignment is not executed.

  According to the present invention, even when installed in a venue with the speciality that the number and arrangement of the output devices are hardly changed, the scene data includes the input patch assignment instruction information, but the output side patch Since the allocation instruction information is not included, the environment on the output side is rarely forcibly changed by calling the scene, and the fixed allocation on the output side can be maintained. If the scene data includes information specifying the assignment of the input part insert patch, the assignment of the output port may be changed accordingly, so that the output port is not currently in use. The assigned assignment is executed so that the fixed assignment on the output side can be maintained. In this case, if the output port is already in use, output a message or search for an empty output port, and if there is an empty output port, execute the indicated assignment for the output port, If there is no free output port, the instructed assignment is not executed, so that the assignment on the output side is not changed without the user's knowledge. As described above, the patch function and scene data recording / calling function can be operated unintentionally by the user even when it is installed in a venue with special characteristics such that the number and arrangement of output devices are hardly changed. It can be realized without doing.

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

  FIG. 1 shows a hardware configuration diagram of a digital mixer according to an embodiment of the present invention. This digital mixer includes a CPU (central processing unit) 101, a random access memory (RAM) 102, a read only memory (ROM) 103, a detection circuit 104, an operator 105, a display circuit 106, a display unit 107, a signal processing circuit 108, A music signal input / output device 109, a communication interface (I / F) 110, and a communication bus 112 are provided.

  The CPU 101 is a processing device that controls the operation of the entire digital mixer. The RAM 102 is a volatile memory that loads a program executed by the CPU 101 and secures various buffer areas. The ROM 103 is a non-volatile memory that stores programs executed by the CPU 101 and various data. The operation element 105 is various switches and faders provided on the external panel of the digital mixer. The operation of the operator 105 is detected by the detection circuit 104, and the operation information is sent to the CPU 101. The display 107 is a display provided on the external panel of this digital mixer. The display circuit 106 displays various types of information on the display unit 107 in accordance with instructions from the CPU 101. The signal processing circuit 108 is a DSP that executes various micro programs based on instructions from the CPU 101, and performs a mixing process, an effect applying process, a volume level control process, and the like of a signal input from the musical tone signal input / output device 109. The processed signal is externally output via the musical tone signal input / output device 109. The communication I / F 110 is an interface for connecting various external devices 111.

  FIG. 2 is a block diagram showing a functional configuration of the digital mixer of FIG. 201 indicates a plurality of input ports. An acoustic signal source such as a microphone is connected to these input ports 201. The input port 201 may input the digital audio signal as it is, or may allow the input port 201 to have an analog / digital conversion function and input the converted digital signal as necessary. . The number of input ports 201 is arbitrary, but it is assumed that there is an upper limit according to the device configuration. The input patch 203 performs assignment (connection) to the input channel 204 and the stereo input channel 205 from the input port described above. The input patch can be arbitrarily set while the user looks at a predetermined screen. The input channel 204 is a single 48 channel. The stereo input channel 205 is provided with 4 groups (2 × 4 channels), and the left signal (L) and the right signal (R) of each group are controlled in pairs. The number of channels is an example and may be arbitrarily changed.

  The signals of each input channel 204 and stereo input channel 205 can be selectively output to any of 16 MIX buses 206 or stereo buses (Stereo_L / R, C) 207. In addition, the parameters for each of these input channels 204 and 205 can be independently set and changed by a controller group (operator 105 in FIG. 1) corresponding to the input channel.

  Each of the 16 buses of the MIX bus 206 mixes signals input from the input channel 204 and the stereo input channel 205. The mixed signal is output to the MIX output channels 210 (1 to 16 channels) corresponding to the MIX bus. Each channel is associated with the MIX bus 206 and the MIX output channel 210 in a one-to-one correspondence. The output of the MIX output channel 210 is input to the output patch 213. The stereo bus 207 mixes signals input from the input channel 204 and the stereo input channel 205. The mixed stereo signal is output to the stereo output channel 209. The output of the stereo output channel 209 is input to the output patch 213. The parameters for each of the output channels 209 and 210 can be independently set and changed by the controller group (operator 105 in FIG. 1) corresponding to the output channel.

  Output signals of the stereo output channel 209 and the MIX output channel 210 are output to the output patch 213. The output patch 213 assigns (connects) the output channels 209 and 210 to the output ports. The assignment can be arbitrarily set while the user looks at a predetermined screen.

  The input section insert patch 221 performs allocation from the signal extraction port of each input channel 204 to the output port and allocation from the input port to the signal input port of each input channel 204. The input section insert patch can be arbitrarily set while the user views a predetermined screen. Each input channel includes a portion for performing various signal processing such as a high-pass filter, an equalizer, and dynamics, but the user determines where the signal extraction port and the signal intake port of the insert are set in the channel signal path. Can be set on the insert point setting screen. The input patch 203 and the input part insert patch 221 are collectively referred to as an input part patch.

  The output part insert patch 222 assigns the signal of each channel of the stereo output channel 209 or the MIX output channel 210 to the output port and assigns the signal of each output channel from the input port to the input port. The setting of the output part insert patch can be arbitrarily performed while the user looks at a predetermined screen. The setting of the insert point is the same as that of the input section insert patch. The output patch 213 and the output part insert patch 222 are collectively referred to as an output part patch.

  The input port and the output port in FIG. 2 correspond to a connection portion between the tone signal input / output device 109 and the signal processing circuit 108 in FIG. The portions other than the input port and the output port in FIG. 2 mainly correspond to the signal processing circuit 108 in FIG. The signal processing circuit 108 operates according to the microprogram and parameters sent from the CPU 101, thereby realizing the mixer having the functional configuration shown in FIG.

  FIG. 3A shows the configuration of the current patch buffer in the digital mixer of this embodiment. The current patch buffer stores input patch data 301, input part insert patch data 302, output patch data 303, and output part insert patch data 304 indicating the setting states of the respective patches 203, 221, 213, and 222 at the present time. To do. When the settings of these patch data 301 to 304 are changed, the CPU 101 immediately sends the patch data (or a parameter for setting the allocation corresponding to the patch data) to the signal processing circuit 108, thereby causing the processing shown in FIG. Control is performed so that the assignment states of the patches 203, 221, 213, and 222 always match the patch data 301 to 304 on the current patch buffer of FIG.

  FIG. 3B shows the configuration of the current parameter buffer. The current parameter buffer stores values of a plurality of parameters other than the patch data shown in FIG. Specifically, a parameter value 311 for each input channel, a parameter value 312 for each stereo input channel, a parameter value 313 for each MIX output channel, a parameter value 314 for each stereo output channel, and other parameter values (patch settings are changed). Excluding) 315. Similar to the above-described patch data, the parameter values in the current parameter buffer define the setting states (excluding the patch settings) of each part in FIG. When these parameter values 311 to 315 are changed in setting, the CPU 101 immediately sends the parameter values (or parameter values generated from the parameter values) to the signal processing circuit 108, whereby the input channel 204 and the stereo input in FIG. Control is performed so that the parameter setting states of the channel 205, the stereo output channel 209, the MIX output channel 210, and other units always match the parameter values 311 to 315 on the current parameter buffer in FIG.

  FIG. 3C shows the configuration of the input unit patch library. In this mixer, the state of the input section patch, that is, the setting state of the input patch 203 and the input section insert patch 221 in FIG. 2 (in terms of data, the input patch data 301 and the input section insert patch data 302 in FIG. 3A) are set. , And can be recorded as an input unit patch library. The input unit patch library includes a plurality of library numbers as shown in FIG. With areas. If the user has a library number Is specified to record the current input section patch in the library, the input patch data 301 and the input section insert patch data 302 of the current patch buffer in FIG. Are recorded as input patch data 321 and input section insert patch data 322. If the user has a library number Is specified and the input section patch is instructed, the designated library No. The input patch data 321 and the input part insert patch data 322 are called to the input patch data 301 and the input part insert patch data 302 of the current patch buffer, and the assignment state of the input part patch is thereby set.

  FIG. 3D shows the structure of the scene data. In this mixer, the setting state of the mixer can be recorded as scene data. The scene data includes a plurality of scene numbers. With areas. When the user selects a scene no. Is designated to record the current setting state, the parameter values 311 to 315 of the current parameter buffer in FIG. Parameter values 331 to 334 and 336. Also, the user can determine whether or not to record the patch setting state in the scene. However, only input unit patches can be recorded in a scene, and output unit patches cannot be recorded. When there is an instruction to record the setting state of the patch in the scene, which library No. of the input unit patch library described in FIG. The user specifies whether to record the input part patch as a scene. For the designated scene number. Library No. Record as 335. If the patch settings are not recorded in the scene, the library No. NULL is recorded in 335. When the user selects a scene no. Is specified, and the mixer setting state is called, the specified scene No. Parameter values 331 to 334 and 336 are read out and set to the parameter values 311 to 315 of the current parameter buffer in FIG. If 335 is not NULL, the library No. The input patch data 321 and the input part insert patch data 322 of the library are read out and set in the input patch data 301 and the input part insert patch data 302 of the current patch buffer in FIG. 303 and the output part insert patch data 304 remain the same). Thereby, the setting state of the called scene is reproduced.

  The mixer according to the present embodiment is assumed to be used in such a manner that the number and arrangement of output devices are hardly changed. Therefore, the mixer includes an input unit patch library. Not prepared. This is because the function of changing the setting of the output section patch is provided, but it is not necessary to record the output section patch as a library. In addition, the library No. Only information that specifies the output side patch is not included. When a scene is recalled, its library No. In some cases, the input part patch library is read, and the input part insert patch data of the current patch buffer is changed. At this time, if the input section insert patch includes an output port assignment change, the output port assignment is changed. As described above, the mixer of the present embodiment assumes that the environment on the output side is used in a substantially fixed manner, and it is considered that there are many cases where the change of output port assignment is not intended by the user. Therefore, in this embodiment, when the assignment of an output port is likely to be changed by calling a scene, it is checked whether or not the output port is in use, and if it is in use, an empty output port is searched for. It is recommended to be assigned to. This specific processing procedure will be described later with reference to FIG.

  FIG. 4 is a flowchart of output patch setting processing executed by the CPU 101. This process is started when the user displays the output patch setting screen by a predetermined operation. On the output patch setting screen, the currently set output channel and output port allocation status (setting status of the output patch 213 in FIG. 2) is displayed. First, in step 401, an instruction to change the assignment of output ports and output channels by the user is received on the displayed output patch setting screen. When an allocation change instruction is received in step 402, it is detected in step 403 whether the corresponding output port is already allocated to any output channel. If the allocation is in progress in step 404, the fact that the allocation is in progress is presented in step 405, and the user is inquired whether the new allocation is valid. When an instruction to validate the new assignment is detected in step 406, the instructed change is overwritten in the current patch buffer (output patch data 303 in FIG. 3A) in step 407, and step 403 is performed. The corresponding portion of the current patch buffer is changed so as to cancel the assignment of the output port in the output channel that was being assigned detected in step (1). With the change of the current patch buffer, the setting state of the output patch (213 in FIG. 2) in the signal processing circuit 108 is also changed. After step 407, the process returns to step 401 to accept the next instruction.

  If it is not an instruction to validate the new assignment in step 406, the process returns to step 401. If it is determined in step 404 that the corresponding output port is not being allocated, the process proceeds to step 407 to execute the instructed allocation change. If it is not an instruction to change the assignment in step 402, it is determined in step 408 whether an instruction to end the setting of the output patch has been received. If so, the process ends. If it is not an end instruction, the process returns from step 408 to step 401.

  Although FIG. 4 has been described by taking the setting of the output patch 213 as an example, the setting of the input patch 203 is the same. The “output” in FIG. 4 may be read as “input”. What is changed is the input patch data 301 in FIG. The setting of the input part insert patch 221 and the output part insert patch 222 is also the same. However, in the setting process of the input section insert patch 221, both the assignment of the input port and the input channel insert point (signal intake port) and the assignment of the output port and the input channel insert point (signal extraction port) are performed. Do. As a result, the input section insert patch data 302 shown in FIG. In the setting process of the output section insert patch 222, the assignment of the input port and the stereo output channel or MIX output channel insert point (signal intake port), and the output port and the stereo output channel or MIX output channel insert point ( Both allocation with the signal extraction port) is performed. As a result, the output part insert patch data 304 shown in FIG.

  FIG. 5 is a flowchart of input part patch library creation processing executed by the CPU 101. This process is executed when the user displays a library setting screen by a predetermined operation and gives an instruction to write the current state of the input unit patch into the library. In this writing instruction, which library No. Whether to write to is specified. In step 501, the input section patches (input patch data 301 and input section insert patch data 302) of the current patch buffer of FIG. 3A are stored in the library No. specified in the input section patch library of FIG. To record. As described above, there is no output unit patch library.

  FIG. 6 is a flowchart of the scene data writing process executed by the CPU 101. This process is executed when the user instructs writing (store) of scene data by a predetermined operation. In this writing instruction, which scene No. Whether to write to is specified. In step 601, the designated scene No. Library No. of the input patch library you want to write to Accept the settings. If there is an instruction not to write the input section patch to the scene, step 601 is skipped. If execution of scene data writing is instructed in step 602, the library number of the input patch library is entered in step 603. Is set, and if it is set, in step 604, the scene number designated by the parameter value 311 to 315 of the current parameter buffer of FIG. Are recorded in parameter values 331 to 334 and 336, and in step 605, the library number of the set input patch library is set. Is the library number of the scene. Add as 335 and end the process. In step 603, the library number of the input patch library. Is not set, in step 606, the parameter values 311 to 315 of the current parameter buffer in FIG. 3B are recorded in the parameter values 331 to 334 and 336 of the designated scene, and the library No. 335 is set to NULL, and the process ends.

  FIG. 7 is a flowchart of the scene data reading process executed by the CPU 101. This process is executed when the user instructs to read (recall) scene data by a predetermined operation. In this readout instruction, which scene No. Whether to read is specified. In step 701, it is detected whether an input section insert patch is recorded in the designated scene. Specifically, the library No. 335 is not NULL, and its library No. It is determined whether or not the input part insert patch is recorded in the library specified by 335. Library No. Is not recorded or is recorded, but its library No. If the input part insert patch is not recorded in the library, the setting state is changed based on the remaining parameters in step 703, and the process is terminated. In this process, the parameter values 331 to 334 and 336 of the scene are read and set as the parameter values 311 to 315 of the current parameter buffer in FIG.

  If an input section insert patch is recorded in the scene in step 702, one allocation instruction from the input section insert patch to the output port is taken out in step 711. Next, in step 712, the allocation status (current status) in the current current patch buffer of the output port for which allocation is instructed (the extracted output port) is detected. If the output port is already allocated in step 713, an output port (empty output port) that is not allocated is detected in step 714. If there is a vacant output port in step 715, in step 716, the allocation instructed is executed with the detected vacant output port as the allocation destination instead of the extracted output port. Thereafter, the process proceeds to step 718.

  If it is determined in step 713 that the output port is not being allocated, in step 717, output port allocation is executed based on the extracted allocation instruction, and the flow advances to step 718. If no empty output port is detected in step 715, the process proceeds to step 718. In step 718, it is determined whether there is an assignment instruction to the output port that has not been taken out from the read input section insert patch. If not, return to Step 703. If the read input section insert patch does not include an output port assignment instruction, the output port assignment instruction cannot be taken out in step 711, and therefore the process proceeds directly from step 711 to step 703 (not shown in the flowchart). .

  In the above embodiment, the program for performing the processing described with reference to FIGS. 4 to 7 is stored in the ROM 103, but instead of the ROM 103, the control program and data are stored in the HD or CD-ROM. The program may be read into the RAM 102 and executed, or a control program and data may be downloaded and executed from a server computer via a communication network.

  If YES is determined in step 713, steps 714 to 716 may not be executed, the user may be informed that assignment is in progress, and the process may proceed to step 718 without executing any assignment. If the determination in step 713 is YES, the user is informed that the assignment is in progress, the user is inquired about whether or not to execute the automatic assignment, and if there is a response, the process goes through steps 714 to 716. The process proceeds to step 718. If there is a reply if not, the process may proceed to step 718 without executing steps 714 to 716.
