Description

  The present invention relates to an electronic music apparatus and program that can be used by extending a timbre by connecting an external electronic music apparatus that newly includes a sound source. In particular, even when an electronic music apparatus having different timbre parameter information attached to the same type of parameters for performing similar sound source control, the user follows all common timbres including extended timbres according to a common operation system. The present invention relates to an electronic music apparatus and a program that can be controlled.

Conventionally, by connecting an external electronic music device or the like including a sound source, the connected external electronic music device is provided in addition to the timbre set in the sound source provided in advance by the device itself. 2. Description of the Related Art There is known an electronic music apparatus that can select and use a timbre set for a sound source (referred to as an extended timbre to be distinguished from a timbre set for a sound source provided in the apparatus itself). As an example of such an electronic music apparatus, there is a musical tone synthesizing apparatus described in Patent Document 1 shown below. In the musical tone synthesizer disclosed in Patent Document 1, the expansion of the timbre is realized by mounting an extended timbre board as an external electronic music device in the main body of the musical synthesizer.
JP 2000-89760

  In general, in order to control the timbre, the timbre parameter generated based on the operation of a predetermined operator must be transmitted to each sound source using program change or control change (for example, MIDI). in the case of). However, if the manufacturer or model of the electronic music device equipped with the sound source is different, the information assigned as the timbre parameters such as the timbre name and its arrangement must be defined differently for each electronic music device. Therefore, in order to perform appropriate timbre control on the sound source of these electronic music apparatuses, it is necessary to transmit corresponding timbre parameters in accordance with each electronic music apparatus. By the way, in the case where the extension of the timbre is realized by newly connecting an extension timbre board (external electronic music apparatus) to the electronic music apparatus main body, the sound source installed in the apparatus main body as much as possible. It is preferable that the timbre (extended timbre) of the additional timbre board (sound source) additionally connected can be controlled in the same way so that the user can use it easily and easily. However, like the musical tone synthesizer described in Patent Document 1 described above, conventionally, only the point of selecting the timbre of the extended timbre board from the apparatus main body is considered, and the timbre and the extended timbre of the apparatus itself are used. In order to enable the same control, no consideration has been given to how to assign the timbre parameter information to a predetermined operator. In particular, when the timbre parameter information for controlling the timbres of the extension sound board connected to the sound source provided in advance in the apparatus main body is different, how to assign the timbre parameter information to a predetermined operator It is a very big problem to assign to a predetermined operation element because it affects the usability of the user. Therefore, it has been desired to provide an electronic music apparatus and program in consideration of these points.

  The present invention has been made in view of the above points, and receives individual timbre parameter information (unique parameter information) from each of external electronic music devices including at least a connected sound source, and uses the timbre parameter information as a common timbre. An electronic music apparatus in which the sound source of a plurality of electronic music apparatuses having different timbre parameter information can be controlled in the same manner according to a common operation system by converting the parameter information into parameter information and assigning it to a predetermined operator. And to provide a program.

  An electronic music apparatus according to claim 1 of the present invention connects an operator, storage means for storing predetermined timbre parameter information including a common control code, and one or more external electronic music apparatuses including at least a sound source. A connection means; an acquisition means for acquiring predetermined unique parameter information including at least a unique control code from each of the connected electronic music devices; and a unique control code of the obtained unique parameter information based on the stored timbre parameter information. Corresponding means for associating a common control code, assigning means for assigning the associated common control code to the operator, and converting the common control code generated in response to the operation of the operator into a unique control code Conversion means for performing similar sound source control Characterized in that even when the connecting electronic musical apparatus unique control code which is different to the species of the parameters are assigned to like can be assigned to parameters of the same type on a common operating element.

  According to the present invention, predetermined unique parameter information including at least a unique control code is obtained from one or more external electronic music devices including at least a sound source, and the unique control of the obtained unique parameter information is performed based on the stored timbre parameter information. Map common control codes to codes. Then, the associated common control code is assigned to the operator. When this operator is operated, the common control code generated in response to the operation is converted into a unique control code. As a result, even when an electronic music device with a different unique control code is attached to the same type of parameter for similar sound source control, the same type of parameter for similar sound source control is used as a common operator. Since the assignment can be easily performed, the user can control all the timbres including the extended timbre according to the common operation system.

  The present invention can be constructed and implemented not only as a device invention but also as a method invention. Further, the present invention can be implemented in the form of a program of a processor such as a computer or a DSP, or can be implemented in the form of a storage medium storing such a program.

  According to the present invention, individual parameter information (unique control code) is individually received from an external electronic music apparatus having at least a sound source, and converted into common timbre parameter information (common control code) to perform a predetermined operation. Since it is assigned to the child, the user can control all the timbres including the extended timbre according to the common operation system.

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

  First, an outline of the operation of the electronic music apparatus according to the present invention will be described with reference to FIG. FIG. 1 is a block diagram showing an example of the entire configuration of a network system including at least one or more external electronic music devices to which an electronic music device according to the present invention can be connected. As shown in FIG. 1, the network system uses a master electronic music apparatus MS according to the present invention as one or more slave electronic music apparatuses TS (at least through a communication network X such as a LAN (local area network)). (Including a sound source). As will be described in detail later, the master electronic music device MS and the slave electronic music device TS are each composed of an electronic music device such as an independent electronic musical instrument or personal computer including a CPU, ROM, RAM, communication interface, sound source, etc. Various kinds of information can be transmitted and received between the master electronic music apparatus MS and the slave electronic music apparatus TS connected to each other via a communication network X such as a radio.

  The master electronic music apparatus MS (hereinafter simply referred to as “master”) is, for example, a master keyboard with a built-in sound source, which has at least an operator and a display for controlling each slave electronic music apparatus TS (hereinafter simply referred to as “slave”). However, a built-in sound source is not essential for the master MS. On the other hand, the slave TS is at least one sound source, for example, a sound source module. Of course, the slave TS may have an operator such as a keyboard. The master MS is connected to each slave TS via the communication network X, and a tone name list corresponding to each tone generator method (for example, tone synthesis method such as FM, PCM, physical model, formant synthesis) from each connected slave TS, and Receives unique timbre parameter information (unique parameter information) including a parameter name list and the like. Here, the unique parameter information of each slave TS (including the master MS if the master MS has a built-in sound source) is the same parameter for performing similar sound source control in each electronic music device. Different information is attached to each of them, and each has its own timbre name list and parameter name list. Therefore, when controlling the sound sources of the slave TSs of different manufacturers and models from the master MS using a common operation mode, it is necessary to absorb such differences in the unique parameter information in each electronic music apparatus.

  Therefore, in the master MS, a plurality of sound sources provided in the electronic music devices of the master MS and the slave TS are displayed in a common display mode by converting a unique parameter name into a common parameter name for each electronic music device. And control according to the operation system. Although details will be described later, specifically, a unique tone name list and a parameter name list (unique parameter information) sent from each slave TS are analyzed in the master MS, and the tone name is one of similar common tone names. Each parameter name is assigned to a common parameter name having a similar parameter name and stored (see “Common Parameter Name List” shown in FIG. 3 described later). In this way, the master MS selects the tone color of one of the slave TSs already connected via the communication network X (see “Tone Color Name List Display Screen” shown in FIG. 6 to be described later). The original parameters of the sound source mounted on the slave TS are displayed in a common display mode on the display 6A of the master MS (see “parameter setting screen” shown in FIG. 7 described later), and the setting operator 5A of the master MS, etc. Can be used to set the tone color parameters of the slave TS. That is, according to the operation of the setting operator 5A of the master MS, all sound sources including the sound sources of the slave TSs can be controlled by the same operation according to the common operation system.

Note that the above-described connection between the master MS and the slave TS may be direct one-to-one connection using various connection cables, or may be one-to-many network connection via the communication network X as described above. Good. Also, any communication protocol may be employed for various connections (for example, MIDI, USB, IEEE1394, Bluetooth (TM), wireless, wired LAN, etc.).
In the network connection as described above, the “master” electronic music device MS and the “slave” electronic music device TS are notionally named for convenience, and their roles are not limited to those determined from the beginning. The role may be arbitrarily changed. For example, the electronic music device that first participates in the network may be the “master” electronic music device MS, and the electronic music device that participates later may be the “slave” electronic music device TS.

  Next, the hardware configuration of the electronic music apparatus (the master electronic music apparatus MS) according to the present invention will be described with reference to FIG. FIG. 2 is a hardware configuration block diagram showing an embodiment of the overall configuration of the electronic music apparatus according to the present invention. Since the slave electronic music apparatus TS that can be connected to the master electronic music apparatus MS via the communication network X can be described as using the same hardware configuration, the master electronic music apparatus MS is representatively shown here. This will be described with reference to the block diagram of FIG.

  The electronic music apparatus (master electronic music apparatus MS) shown in this embodiment is controlled by a microcomputer including a microprocessor unit (CPU) 1, a read only memory (ROM) 2, and a random access memory (RAM) 3. The CPU 1 controls the operation of the entire electronic music apparatus. The CPU 1 is connected to the ROM 1, RAM 3, detection circuits 4 and 5, display circuit 6, tone generator circuit 7, effect circuit 8, external storage device 10, MIDI interface (I / F) 11 and the like via the data and address bus 1D. Communication interfaces (I / F) 12 are connected to each other. Further, the CPU 1 is connected to a timer 1A for measuring the interrupt time and various times in the timer interrupt process (interrupt process). For example, the timer 1A generates a clock pulse, and gives the generated clock pulse to the CPU 1 as a processing timing command or to the CPU 1 as an interrupt command. The CPU 1 executes various processes according to these instructions.

  The ROM 2 stores various programs executed by the CPU 1 and various data. The RAM 3 is used as a working memory that temporarily stores various data generated when the CPU 1 executes a predetermined program, or as a memory that stores a currently executed program and related data. A predetermined address area of the RAM 3 is assigned to each function and used as a register, flag, table, memory, or the like. The performance operator 4A is, for example, a keyboard provided with a plurality of keys for selecting the pitch of a musical tone, and has a key switch corresponding to each key. The keyboard etc. can be used not only for performance but also as input means for inputting various settings. The detection circuit 4 generates a detection output by detecting the pressing and release of each key of the performance operator 4A.

  The setting operators (switches, etc.) 5A are various operators such as parameter control operators (see FIG. 4 described later) for controlling the timbre parameters, or switches. Of course, in addition to these, a numeric data input numeric keypad and a character data input keyboard used for selecting, setting and controlling the pitch, tone, effect, etc., or a predetermined pointer displayed on the display 6A are operated. Various operators such as a mouse used for the purpose may be included. The detection circuit 5 detects the operation state of each switch, and outputs switch information corresponding to the operation state to the CPU 1 via the data and address bus 1D. The display circuit 6 includes, for example, a “sound name list display screen” (see FIG. 6 to be described later), a “parameter setting screen” (see FIG. 7 to be described later), etc. Various screens or the control state of the CPU 1 are displayed. The user can select a timbre category and set parameters of each timbre while referring to these various types of information displayed on the display 6A (see FIG. 5 described later).

  The tone generator circuit 7 can simultaneously generate musical sound signals in a plurality of channels, and is generated in accordance with the operation of the performance operator 4A by the user, which is given via the data and address bus 1D, or based on predetermined performance data. Various kinds of performance information are input, and a musical tone signal is generated based on the performance information. The tone generator circuit 7 controls the tone signal to be generated based on the tone color parameter, and the generated tone signal is generated from the sound system 9 including an amplifier and a speaker via the effect circuit 8. The effect circuit 8 gives an effect to the musical sound signal from the sound source circuit 7. Any conventional configuration may be used for the sound source circuit 7, the effect circuit 8, and the sound system 9. For example, the tone generator circuit 7 may employ any of various tone synthesis methods such as FM, PCM, physical model, formant synthesis, etc., or may be configured with dedicated hardware, or a CPU 1 or DSP (not shown). ) Or the like.

  The external storage device 10 stores various data such as a common parameter list or a unique parameter list (see FIG. 3 described later), various control programs executed by the CPU 1, data related to control, and the like. When no control program is stored in the ROM 2, the control program is stored in the ROM 2 by storing the control program in the external storage device 10 (for example, a hard disk) and reading it into the RAM 3. The CPU 1 can be operated in the same manner as in the case. In this way, control programs can be easily added and upgraded. The external storage device 10 is not limited to a hard disk (HD), but a flexible disk (FD), a compact disk (CD-ROM / CD-RAM), a magneto-optical disk (MO), a DVD (Digital Versatile Disk), etc. Any storage device may be used as long as the storage device uses various external storage media. Alternatively, a semiconductor memory such as a flash memory may be used.

  The MIDI interface (I / F) 11 inputs MIDI performance data (MIDI data) from another externally connected MIDI device 11A or the like to the electronic music device or performs MIDI performance from the electronic music device. This is an interface for outputting data (MIDI data) to another MIDI device 11A or the like. The communication interface (I / F) 12 is connected to a wired or wireless communication network X such as a LAN, for example, and is connected to an external electronic music device 12A having a sound source via the communication network X. Various data such as unique parameter information can be transmitted and received between the electronic music apparatus 12A (corresponding to the slave TS) and the electronic music apparatus (corresponding to the master MS). Further, a server computer (not shown) or the like can be connected via the communication network X. When no control program or various data is stored in the ROM 2 or the external storage device 10 (for example, a hard disk). Control programs and various data can be downloaded from the server computer. Such a communication interface 12 may include both of a wired interface and a wireless interface.

Needless to say, the MIDI device 11A directly connected via the MIDI interface 11 may be the slave TS.
In the electronic music apparatus described above, the performance operator 4A is not limited to the form of a keyboard instrument, but may be any form such as a stringed instrument, a wind instrument, or a percussion instrument. In addition, the electronic music device is not limited to one having the performance operator 4A and the display 6A incorporated in one device body, but each device is configured separately, and each device is connected using communication means such as a MIDI interface or various networks. Needless to say, it may be configured to do so. Furthermore, the electronic music apparatus according to the present invention is not limited to an electronic musical instrument or a personal computer, but can be applied to any type of apparatus / equipment such as a portable communication terminal such as a mobile phone, a karaoke apparatus, or a game apparatus. May be.

  Next, the data structure of the parameter name list stored and managed on the master MS side and the assignment of each parameter to the parameter control operator will be described. FIG. 3 is a conceptual diagram showing an embodiment of the data structure of the parameter name list. FIG. 3 (a) shows a common parameter name list, and FIG. 3 (b) shows a unique parameter name list associated with common parameters. Each is shown. FIG. 4 is a conceptual diagram showing an embodiment of a parameter control operator that assigns each parameter.

  The common parameter list is predetermined timbre parameter information stored in advance on the master MS side, and a common control code and operator assignment information are stored in association with each common parameter name as shown in FIG. Has been. The common parameter name is a parameter name commonly used for the master MS and the slave TS, and is generally given an appropriate name corresponding to the control content such as “Cutoff” or “Resonance”. The common control code is a control code for controlling the parameter of the common parameter name. By assigning this control code to a parameter control operator commonly used for the master MS and the slave TS, the operator The sound source can be controlled based on the operation. The operation element assignment is information indicating an operation element to which the common parameter or the common control code is assigned. On the other hand, the unique parameter name list is parameter information created on the master MS side based on the unique parameter information received from each slave TS, and is roughly divided as shown in FIG. 3 (b). (Unique parameter name, unique control code, current set value) and information (common control code and operator assignment information) associated on the master MS side based on the common parameter name list. The unique parameter name is a parameter name with an appropriate name corresponding to the control content when each slave TS is used alone. The unique control code is a control code for controlling the parameter having the unique parameter name, and is assigned to the operator provided in each slave TS to control the sound source. The current setting value is the current setting value set in accordance with the operation of the operator assigned to the unique control code included in each slave TS at the time when the unique parameter information is transmitted from each slave TS to the master MS. Is information.

  As described above, the master MS assigns a corresponding common control code and operator assignment to the unique parameter information received from the slave TS. In the embodiment shown here, for example, the unique parameter name “LPF Cutoff” is the same type of parameter that controls the frequency cutoff as the common parameter name “Cutoff”. The common control code “74” is assigned to “Cutoff”. Similarly, since the unique parameter name “LPF Reso” is the same parameter as the common parameter name “Resonance”, the common control code “71” is assigned. On the other hand, the unique parameter name “HPF Cutoff” does not have the same type of parameter in the common parameter name, so even if you refer to the common parameter name list, you cannot assign a common control code and use the original control code as it is. Common control code and operator assignment are not assigned.

  The master MS has a plurality of parameter control operators (for example, knobs and sliders). As shown in FIG. 4, for example, knobs 1 and 2 are used as controls for controlling common parameters. Knob 3 and knob 4 can be assigned as operators for controlling the unique parameters. That is, by appropriately assigning common control codes and common parameter names to the knobs 1 and 2 respectively (common to all timbres), operating the knob 1 or knob 2 makes the sound sources of the master MS and slave TS the same. Can be controlled. For example, when a common control code “74” is assigned to the operation element “knob 1” in order to control the frequency cut-off of the sound source, the common parameter name “Cutoff” is assigned to the knob 1. Here, since the common control code “74” is associated with the unique control code “60” in the slave TS, the knob 1 controls the unique parameter name “LPF Cutoff” of the unique control code “60”. Will be able to. That is, according to the operation of the knob 1, it is possible to control the master MS so that both the sound sources of the master MS and the slave TS are simultaneously cut off. On the other hand, unique control codes are assigned to the knobs 3 and 4 other than these. It may be assigned independently for each timbre, or may be assigned independently for each slave TS (but commonly in one electronic music apparatus). Thereby, only the sound source of the slave TS can be controlled from the master MS according to the operation of the knob 3 or the knob 4.

  The electronic music apparatus (master electronic music apparatus MS) according to the present invention individually acquires unique parameter information from each of one or more slave TSs including at least a sound source connected on the communication network X, and acquires the acquired unique parameters. By assigning a common parameter name and a common control code to the parameter information, each slave TS can be controlled from the master MS according to a common display mode and operation system. The “sound source control process” for performing such a process will be described with reference to FIG. FIG. 5 is a flowchart showing an example of the “sound source control process”. This process is a process that starts when the power is turned on and ends when the power is turned off in each of the master MS and the slave TS. Here, for easy understanding of the explanation, the processing executed by each of the master MS and the slave TS is shown on one drawing, and each processing executed by each of the master MS and the slave TS is explained according to the processing order. To do.

  First, the master MS detects a slave TS connected to the communication network X (step S1). When executing the detection of the slave TS, a predetermined detection signal is transmitted in the communication network X to wait for a response from each slave TS connected to the communication network X. Each slave TS connected to the communication network X always operates in a processing standby state so as to receive the detection signal transmitted from the master MS, and each slave TS that has received the detection signal transmitted from the master MS A response signal is returned to the master MS (step 21). The master MS that has received the response signal from the slave TS requests the slave TS to transmit the timbre name list and the unique parameter name list as the unique parameter information (step S2). In response to the request from the master MS, the slave TS transmits unique parameter information (tone color name list and unique parameter name list) corresponding to the sound source to the master MS (step S22). The master MS analyzes the timbre name list received from the slave TS and groups the timbres included in the timbre name list into timbre categories. Then, based on a predetermined instruction from the user, a “tone color list display screen” as shown in FIG. 6 can be displayed on the display 6A.

  Here, the “tone color name list display screen” displayed on the display 6A of the master MS based on the user instruction will be briefly described. FIG. 6 is a conceptual diagram showing an example of a “tone name list display screen”. This “timbre name list display screen” is a screen for facilitating selection of a timbre for parameter assignment. In this embodiment, a screen displayed when “Piano” is selected as the tone color category is shown. As described above, timbre name lists from a plurality of electronic music apparatuses are grouped for each timbre category and managed together. Therefore, for example, when the user designates the timbre category “Piano” with an operator (not shown), the timbre names classified into the timbre category “Piano” are collectively displayed as shown in FIG. When one of the timbre names is selected by the number (No) added to each timbre name on the “timbre name list display screen”, a “parameter setting screen” (described later) displaying the common parameters of the selected timbre. Is displayed).

  Returning to the description of the flowchart of FIG. 5, in step S4, the unique parameter name list received from the slave TS is analyzed, and common parameters are assigned. That is, a common control code and an operator assignment are assigned to each unique parameter name included in the received unique parameter name list based on the common parameter name list (see FIG. 3). As a method for assigning the common parameter, for example, a method of assigning a pre-corresponding for each manufacturer or model, a method of assigning a corresponding parameter by matching a common parameter name with a character string for each unique parameter name, etc. It may be the method of. At the time of this common parameter assignment, a “parameter setting screen” as shown in FIG. 7 is displayed on the display 6A, and the assignment content can be modified as required by the user, and the common parameter is assigned. It is also possible to set to assign a controller assignment for a unique parameter name that did not exist.

  Here, the “parameter setting screen” displayed on the display 6A of the master MS will be briefly described. FIG. 7 is a conceptual diagram showing an example of a “parameter setting screen”. This "parameter setting screen" is a screen that is displayed when a desired tone name is selected in the above-mentioned "tone name list display screen", such as changing or setting the control code assigned to each parameter or operator assignment. It is for making it easier. In this embodiment, a screen displayed when the timbre name “Classic Piano” (device type is slave 1) of the timbre category “Piano” is selected. Of the unique parameter information included in the sound name “Classic Piano” of slave 1, the unique parameter names “LPF Cutoff” and “LPF Reso” are the common parameter names “Cutoff” and “Resonance”, and the common control codes “74” and “74”, respectively. 71 ”is assigned. The unique parameter name “HPF Cutoff” is not assigned because there is no corresponding common parameter name, and the unique parameter name “HPF Cutoff” and the unique control code “62” are assigned as they are. "*" Mark is displayed to show) For the unique parameter name “HPF Cutoff”, an operator assignment cannot be assigned based on the common parameter name list. Therefore, the user needs to appropriately assign an operator to the unique parameter to which the common parameter cannot be assigned, and “knob 3” is assigned here.

  Returning to the description of the flowchart of FIG. 5, in step S5, each control code is assigned to a parameter control operator. In step S6, a timbre to be used in the master MS and each slave TS is selected in accordance with a user operation. In step S7, it is determined whether or not the user has operated the operator. The processing in step S7 is repeated until it is determined that the operation element has been operated (NO in step S7). If it is determined that the operation element has been operated (YES in step S7), it is determined whether or not the operated operation element is a common operation element among the parameter control operation elements (step S8). If it is a common operator (YES in step S8), the common control code assigned to the operated operator is converted into a unique control code, and the converted unique control code and the operation of the operator are used. Both of the manipulated values are transmitted to the slave TS (step S9). On the other hand, when the operated operator is not a common operator among the parameter control operators but a unique operator (NO in step S8), the unique control code assigned to the operated operator and the An operation value corresponding to the operation of the operator is transmitted to the slave TS (step S10). The slave TS controls the sound source according to the unique control code and the operation value transmitted from the master MS (step S23). After the above-described processing ends, “other processing” is executed in each of the master MS and the slave TS (step S11 or step S24). “Other processing” executed on the master MS side includes, for example, processing for transmitting a performance event or the like to the slave TS corresponding to the selected tone color. On the other hand, “other processing” executed on the slave TS side includes, for example, processing for receiving a performance event from the master MS and controlling sound generation.

  As described above, the master electronic music device MS acquires the unique parameter information from each slave electronic music device TS connected via the communication network X at the time of activation, and the common parameter for the obtained unique parameter information. Assign common parameters by referring to the name list. If the operated parameter control operator is assigned as a common operator when the parameter control operator of the master electronic music apparatus MS is operated, the master electronic music apparatus MS is operated according to the operation of the operator. And the sound source of the slave electronic music apparatus TS are controlled simultaneously. When the operated parameter control operator is assigned as a unique operator, only the assigned sound source of the master electronic music apparatus MS or the slave electronic music apparatus TS is controlled. In this way, each of the plurality of slave electronic music apparatuses TS to which different timbre parameter information is attached to the same type of parameters for performing similar sound source control from the master electronic music apparatus MS is displayed according to a common display mode and operation system. Will be able to control. Note that the acquisition of the unique parameter information from each slave TS is not limited to the time of activation but may be at an arbitrary timing.

Note that the above-described timbre names, parameter names, types, and the like are not limited to those illustrated.
Needless to say, the common parameter name list has one list corresponding to each sound source method.
The common parameter name and common control code may be selected from a plurality of types of sets. For example, each electronic music apparatus may have a set, and a common parameter name and a common control code of any selected electronic music apparatus set may be used.
The rules for analyzing the parameter name list are not limited to those provided in the master electronic music apparatus MS from the beginning, but can be supplied from a server computer or an external storage medium connected on the communication network X. This is advantageous because it can easily cope with the case where a new slave electronic music apparatus TS is connected to the communication network X.
