Description

  The present invention relates to a musical sound generating apparatus and program having a sound source having a plurality of parts and capable of functioning as either a single sound source or multiple sound sources. In particular, the present invention relates to a musical sound generation apparatus and program that can easily adjust musical sound generation parameters specific to each part when the sound source is functioning as a multi sound source having a plurality of parts.

Some conventionally known musical sound generation apparatuses can generate musical sounds by greatly changing the structure of a sound source such as a part configuration and a memory configuration in accordance with user selection. As an example of such a musical sound generating device, for example, one described in Non-Patent Document 1 shown below can be cited. In the device described in Non-Patent Document 1, the sound source is composed of only one part, and one voice (tone) is received in response to receiving only one channel of MIDI data having a single channel number from an external keyboard or the like. "Voice mode" (sound source functions as a so-called single sound source) for generating musical sounds in the sound source, the sound source is composed of multiple parts (for example, up to 16 parts), and MIDI data with different channel numbers (for example, 1 to 16) from the sequencer etc. The “Song / Pattern mode” (sound source functions as a so-called multi-sound source) can be selected in which a plurality of parts generate musical sounds with different voices. Furthermore, while the sound source is made to function as a single sound source in the same way as in the “voice mode”, the sound source is configured not only by one part but also by a predetermined number of specific parts (for example, a maximum of 4 parts). In response to receiving MIDI data of one channel with a single channel number, the specific part generates music with different voices at the same time, so that multiple different voices can be layered (ie, layered). The "performance mode" to be generated can also be selected.

  In addition, in the conventional musical sound generation device, in order to realize the above-described musical sound generation on a sound source that can function with either a single sound source or multiple sound sources, not only a part configuration but also a memory configuration for generating musical sounds, a musical sound generation parameter, etc. Is stored in advance for each mode. For example, as the sound source setting data for “Song / Pattern Mode”, a parameter set unique to each part and a parameter set common to all the parts are stored. The sound source setting data is automatically switched according to the mode switching.

  By the way, regarding the tone generation parameters specific to each part included in the sound source setting data used in the “song / pattern mode”, the user can operate the control elements such as knobs and faders while listening to the tone (performance) actually played. The settings can be arbitrarily adjusted (setting change) by appropriately operating the class. By adjusting parameters while listening to the performance, the user can easily finish the musical tone according to the image. However, in the “Song / Pattern mode”, the user must set parameters for each part in a state where multiple parts are operating according to data input from the sequencer, that is, in a situation where multiple voices are mixedly sounded. Adjustments must be made. For this reason, it is difficult for the user to grasp the change of the musical tone due to the parameter adjustment operation, and in order to finish the musical tone according to the image, only the parameter adjustment can be performed by trial and error. It was very difficult to make adjustments.

  Therefore, it is conceivable to perform parameter adjustment for each part using the “voice mode” described above. In other words, the data input from the sequencer is temporarily switched to the data input from the external keyboard, etc., and the musical sound is generated only in one part among a plurality of parts based on the single one-channel MIDI data received from the external keyboard. It is possible to adjust the tone generation parameters only for the part. However, in order to generate a musical tone at the same time only for any specific part of multiple parts based on a single channel of MIDI data received from an external keyboard, all the received channel numbers of the specific parts are all It is necessary to change to match a single channel received from the external keyboard. In addition, after adjusting the parameters, it is necessary to return the received channel numbers to the original received channel numbers for all the parts where the received channel numbers have been changed in order to individually generate musical sounds according to the MIDI data received from the sequencer again. For this reason, it is very troublesome to perform such an operation every time the parameter is adjusted.

Furthermore, it is also possible to adjust the tone generation parameters specific to each part using the “performance mode” described above. However, when switching to “Performance Mode”, the musical sound generation currently being executed is interrupted, and in “Performance Mode”, a dedicated data set called “Performance” is used. It is not practical to prepare a large number of “performances” according to the combination of types, etc. Furthermore, when returning to “Song / Pattern mode”, the memory configuration is changed and the above “performance” is not used ( In other words, the tone generation parameters set in the performance mode are not carried over), so that the same parameter adjustment must be performed again when returning to the “Song / Pattern mode”.
From the above, in the conventional apparatus, when the “performance mode” is selected and the sound source functions as a multi sound source having a multi-part configuration, it is very possible to appropriately adjust the tone generation parameters specific to each part. It was difficult.

  The present invention has been made in view of the above points, and in the case where a sound source is functioning as a multi-sound source composed of a plurality of parts, a musical sound that can easily adjust various parameters relating to the generation of musical sounds specific to each part. An object is to provide a generation device and a program.

  The musical sound generating apparatus according to the present invention is a sound source having a plurality of parts, each of the plurality of parts associated in advance with different reception channel numbers, and each of the performance data of the channel number corresponding to the reception channel number and each of the performance data Musical sound generation individually based on musical sound generation parameters specific to the part, storage means for storing a common reception channel number associated with a part of the plurality of parts, and setting means for setting the parameter adjustment mode Data acquisition means for acquiring performance data to which channel numbers are assigned, and control means for instructing generation of musical sounds for each of the plurality of parts, and according to the setting of the parameter adjustment mode, Whether the reception channel number to be associated with some parts is the reception channel number associated in advance Change to the common reception channel number, and when the channel number of the acquired performance data matches the common reception channel number, instruct the musical sound generation based on the performance data to all the parts at the same time And a changing means for changing a tone generation parameter specific to a part for which the tone generation is instructed.

  According to the present invention, a common reception channel in which reception channel numbers associated with some parts among a plurality of parts previously associated with different reception channel numbers are stored in the storage unit according to the setting of the parameter adjustment mode. Change to a number. Therefore, in the parameter adjustment mode, when performance data having a channel number that matches the common reception channel number is acquired, all of the part parts simultaneously start generating musical sounds based on the performance data. That is, when the parameter adjustment mode is set, a multi-sound source in which a corresponding part of a plurality of parts previously associated with different reception channel numbers in response to receiving performance data with different channel numbers generates musical sounds, In response to receiving performance data of a single channel corresponding to a common reception channel number, the sound source function is temporarily transferred to a single sound source in which all of the partial parts simultaneously generate musical sounds based on the same performance data. Change. In this way, by temporarily causing only a part to function as a single sound source from a state where a plurality of parts are functioning as a multi-sound source, and adjusting the tone generation parameters specific to each part with respect to the part part The user can easily adjust the parameters as compared with the situation where a plurality of voices in the multi-sound source are simultaneously generated, and the adjusted parameters can be immediately reflected in the generation of musical sounds in the multi-sound source and confirmed. That is, the user can easily adjust various parameters related to the generation of musical sounds specific to each part.

  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, since the sound source function can be temporarily switched from a multi-sound source having a multi-part configuration to a single sound source having a specific part-part configuration, the user can adjust the parameters. Even in the case of functioning as a multi-sound source, it is possible to easily adjust the tone generation parameters specific to each part.

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

The detection circuit 5 detects the operation state of the setting operator 5A, and outputs switch information or the like corresponding to the operation state to the CPU 1 via the data and address bus 1D.

  The display circuit 6 displays various screens according to the operation of the setting operator 5A on the display 6A constituted by, for example, a liquid crystal display panel (LCD), a CRT, etc. Various data stored in the memory 4 and the external storage device 9 and the control state of the CPU 1 are displayed. The user can easily switch between modes and set various parameters by referring to these various types of information displayed on the display 6A.

  The tone generator circuit 7 has a plurality of parts (in this embodiment, a maximum of 16 parts as shown in FIG. 2 to be described later), and an external keyboard KB (FIG. 2) given by the user via the data and address bus 1D. MIDI format performance data (referred to as MIDI data) generated in response to the performance operation in step 2) or the MIDI format sequentially generated based on the playback of song data or pattern data in the sequencer SQ (see FIG. 2). Performance data is acquired (input), and each part can individually generate a musical tone signal based on these MIDI data. Although details will be described later (see FIG. 2 described later), the same or different MIDI reception channel numbers can be appropriately associated with each part of the tone generator circuit 7, and each part can be associated with each part. The sound source setting data prepared in advance according to the selected mode is read from the nonvolatile memory 4 and set. As a result, in the tone generator circuit 7, each part performs a musical tone generation process based on the performance data with the channel number corresponding to the MIDI reception channel number and the tone generator setting data specific to the part associated with each part. Depending on the execution, it is possible to generate musical sounds with a maximum of 16 kinds of timbres at the same time.

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 configured with software processing by the CPU 1. May be.

  The external storage device 9 stores various data and various control programs executed by the CPU 1. 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 9 (for example, a hard disk) and reading it into the RAM 3. It is possible to make the CPU 1 have the same function as the case. In this way, control programs can be easily added and upgraded. The external storage device 9 is not limited to a hard disk (HD), but may be a flexible disk (FD), a compact disk (CD-ROM / CD-RAM), a magneto-optical disk (MO), or a DVD (Digital Versatile Disk). Any storage device that uses a storage medium of any form may be used. Alternatively, a semiconductor memory such as a flash memory may be used.

  The MIDI interface (I / F) 10 inputs MIDI data from another externally connected MIDI device 10A (for example, a sequencer or an external keyboard) to the device, or receives MIDI data from the device as another MIDI device 10A. This is an interface to output to. The other MIDI device 10A may be any device that generates MIDI data.

  The communication interface (I / F) 11 is connected to a wired or wireless communication network X such as a LAN, the Internet, or a telephone line, and is connected to the server computer 11A via the communication network X, and the server computer 11A. This is an interface for taking control programs or various data from the electronic musical instrument side. Further, when the control program and various data are not stored in the ROM 2 or the external storage device 9 (for example, hard disk), it is used for downloading the control program and various data from the server computer 11A. Such a communication interface 11 may be both wired and wireless and may include both.

Note that the musical sound generating apparatus according to the present embodiment can be used to select the pitch of a musical sound or to set a timbre, an effect, etc., for example, a performance operation such as a keyboard composed of a plurality of keys. A child (not shown) may be provided. Of course, such a performance operator is not limited to a keyboard instrument, and may be any type of operator such as a guitar type, a wind instrument type, a percussion instrument type, or a gesture type.
The musical tone generating apparatus according to the present embodiment is not limited to one in which the performance operator, the display 6A, the tone generator circuit 7 and the like are built in one apparatus body, but each is configured separately, such as a communication interface and various networks. Needless to say, the present invention can be similarly applied to a device configured to connect each device using a communication unit.

  The musical tone generator shown in FIG. 1 has a sound source having a plurality of parts capable of generating musical sounds, and the sound source can be changed by greatly changing the part configuration and the memory configuration in accordance with the selection of each mode described above by the user. The functioning as a single sound source or a multi sound source is the same as in the prior art. On the other hand, in the musical sound generating apparatus according to the present invention, when the “song / pattern mode” is selected, the parameter adjustment on / off switch is set in the normal performance state, that is, when the sound source functions as a multi sound source having a plurality of parts. The performance state for parameter adjustment, that is, the sound source can be temporarily switched so as to function as a single sound source in response to the “on” operation (however, in this case, the part configuration and memory configuration are changed) Switch between multi and single sources without changing).

  In this specification, the normal performance state when “Song / Pattern mode” is selected is based on the playback of song data and pattern data by the sequencer SQ (see FIG. 2), where the sound source functions as a multi-sound source having a plurality of parts. Indicates the state in which the corresponding part generates a musical sound in accordance with the generated multi-channel MIDI data input. On the other hand, the performance state for parameter adjustment (“parameter adjustment mode”) means that the sound source functions as a single sound source, and MIDI data input of a plurality of channels generated based on the playback of song data and pattern data by the sequencer SQ is temporarily performed. It is switched to MIDI data input generated according to the operation of the external keyboard KB, and a plurality of specific parts designated in advance according to the single one-channel MIDI data generated according to the operation of the external keyboard KB. All indicate a state in which musical sounds are generated simultaneously.

  Next, when the “Song / Pattern Mode” is selected, the musical tone is generated by appropriately switching between the normal performance state and the performance state for parameter adjustment according to the operation of the parameter adjustment on / off switch. A sound source having a plurality of parts that can be performed will be described with reference to FIG. FIG. 2 is a block diagram schematically showing an embodiment of a sound source having a plurality of parts. The arrows in the figure indicate the flow of data and signals. The sound source 7 has components other than those shown in FIG. 2, but only the minimum necessary components are shown here.

  The sound source 7 includes a MIDI message control unit CT, a sound source unit TC, and a parameter storage unit K. The tone generator unit TC has a plurality of parts P1 to P16, and tone generator setting data read from the nonvolatile memory 4 in accordance with the selection of the “song / pattern mode” is stored in the parameter storage unit K (for example, the RAM 3). Therefore, according to the stored sound source setting data, the sound source unit CT can function as a multi sound source having a plurality of parts. Further, each of the plurality of parts P1 to P16 executes a tone generation process with reference to the tone generation parameters D1 to D16 specific to each part included in the sound source setting data. That is, it can be said that each of the plurality of parts P1 to P16 is a tone generation unit that generates a tone.

  The musical tone generation processing executed by the plurality of parts P1 to P16 is various types of conventionally known processing, for example, note limit processing in which different voices are played depending on a predetermined range to which the pitch of performance data belongs as shown in the figure. , Velocity limit processing that allows different voices to be played depending on the velocity of the performance data, arpeggio processing that automatically generates various rhythm phrases and chord backing tones, and musical tones generated as a result of each processing Any process may be used as long as a process for generating a musical sound by executing a series of processes such as a voice sound generation process for generating a sound by applying an effect to a signal.

  Regarding the tone generation parameters D1 to D16 unique to each part included in the sound source setting data stored in the parameter storage unit K, the setting values can be arbitrarily changed according to the operation of the parameter setting switch or the like by the user. It is. When the “Song / Pattern mode” is finished (that is, when another mode is selected), the tone generator setting including the specific tone generation data D1 to D16 for each part stored in the parameter storage unit K While the data is written and stored in the nonvolatile memory 4, the sound source setting data corresponding to the other selected mode is read from the nonvolatile memory 4 and stored in the parameter storage unit K. Thereby, the sound source unit CT functions as a single sound source without functioning as a multi sound source.

  The MIDI message control unit CT instructs a plurality of parts P1 to P16 to execute a musical tone generation process based on the MIDI data transmitted from the sequencer SQ. The MIDI message control unit CT receives the basic receive channel setting register BR and the reception. Channel setting registers R1 to R16. The reception channel setting registers R1 to R16 are associated with any one of a plurality of parts P1 to P16, and the MIDI message control unit CT receives reception channel numbers (1 to 16) stored in the registers R1 to R16. In response to the input of MIDI data (one by one), the MIDI data is sent only to one of the parts P1 to P16, and any one of the parts P1 to P16 is operated separately to produce a musical sound. (Ie, the sound source unit TC functions as a multi sound source).

  On the other hand, the basic receive channel setting register BR is associated with a plurality of specific parts (here, four parts P1 to P4 as an example), and the reception channel number (sent from the sequencer SQ) stored in this register BR. In response to the input of MIDI data of a single channel number (for example, 15) assigned to the MIDI data generated based on the performance operation on the external keyboard KB, all corresponding parts P1 to P4 The MIDI data is sent and the parts P1 to P4 are simultaneously operated to generate a musical sound (that is, the sound source unit TC functions as a single sound source). The reception channel number stored in the reception channel setting registers R1 to R16 and the basic receive channel setting register BR and the parts P1 to P16 associated with the registers R1 to R1 and BR can be arbitrarily set by the user. Good.

  The MIDI message control unit CT uses either one of the basic receive channel setting register BR and the reception channel setting registers R1 to R16 when controlling the plurality of parts P1 to P16. In this embodiment, when the parameter adjustment on / off switch is turned on, the basic receive channel setting register BR is used, and the parameter adjustment on / off switch is turned off. Accordingly, the reception channel setting registers R1 to R16 are used.

  Further, the MIDI message control unit CT switches MIDI data transmitted from the sequencer SQ externally connected to the musical tone generating apparatus in accordance with switching of registers to be used. Song data and pattern data are stored in the sequencer SQ. When the reception channel setting registers R1 to R16 are used (in the case of multiple sound sources), the song data or pattern data to be played is reproduced. MIDI data generated in response to each is sent sequentially. On the other hand, when the register BR for basic receive channel setting is used in response to the on / off operation of the parameter adjustment on / off switch (single sound source), the song data to be played to the sequencer SQ Or, pause playback of pattern data (and accompanying MIDI data transmission), and instruct to switch to MIDI data generated when the external keyboard KB connected to the sequencer SQ is operated. To do. In this way, the data input is also switched according to the operation of the parameter adjustment on / off switch. Of course, such switching of data input may be performed by the user manually operating the sequencer SQ in accordance with the operation of the parameter adjustment on / off switch.

  Alternatively, the MIDI message control unit CT may appropriately switch the MIDI data transmitted from the externally connected sequencer SQ according to the channel number of each MIDI data. That is, the MIDI data generated in response to the playback of the song data or pattern data to be played and the external keyboard KB are operated without pausing the playback of the song data or pattern data to be played by the sequencer SQ. Both of the MIDI data generated in response to this are transmitted to the sequencer SQ, and the MIDI message control unit CT sends each MIDI data to the basic receive channel setting register BR or the like according to the channel number assigned to the MIDI data. You may make it distribute to the register | resistor R1-R16 for receiving channel setting. However, in that case, a channel number that does not overlap with the channel number assigned to the MIDI data generated in response to the operation of the external keyboard KB (the same number as the reception channel number set in the register BR) Needless to say, it is added to the MIDI data generated in response to the reproduction of the data or pattern data.

  When the data input is switched to MIDI data generated from the external keyboard KB, the MIDI data of the channel number set in the basic receive channel setting register BR is input (in other words, such MIDI data is input). The external keyboard KB is set to generate data), and all the parts P1 to P4 associated with the basic receive channel setting register BR operate simultaneously. When each of the plurality of parts P1 to P4 executes the tone generation process as described above, the sound source setting data stored in the parameter storage unit K (for example, the RAM 3) is referred to and each part included in the sound source setting data is referred to. Each of the above processes is executed in accordance with the tone generation parameters specific to each.

  It is possible to change the setting values of the tone generation parameters specific to the plurality of parts P1 to P4 that are operated in accordance with the ON operation of the parameter setting switch by the user, and the ON / OFF switch for parameter adjustment is OFF operation Even if it is done, the change is maintained. That is, the sound source setting data stored in the parameter storage unit K is not a kind of data that can be switched to another data in accordance with the operation of the parameter adjustment on / off switch, and is non-volatile when “song / pattern mode” is selected. The data read from the memory 4 is maintained, or the data is changed (edited). Therefore, even if the performance state for parameter adjustment (single sound source) returns to the normal performance state (multi sound source) again, unlike the conventional mode change, the setting value of the musical sound generation parameter changed for the single sound source is maintained as it is. Based on this, a musical tone is generated even in the case of multiple sound sources.

  Next, when the musical sound generating apparatus shown in the present embodiment functions as a multi-sound source, the normal performance state (multi-sound source) and parameter adjustment are performed in response to the operation of the parameter adjustment on / off switch. A process for generating a musical sound while appropriately switching to the performance state (single sound source) will be described with reference to FIG. FIG. 3 is a flowchart showing an example of “multiple sound source processing”. This process is executed by the CPU 1, and starts when “Song / Pattern Mode” is selected, and ends when a mode other than “Song / Pattern Mode” is selected. Is done. In other words, a plurality of parts (for example, 16 channels) of MIDI data is received from a sequencer or the like and a sound source functions as a so-called multi-sound source, so that a plurality of parts perform with different voices as a normal performance state. .

  Step S1 executes initial setting. Initial settings include reading sound source setting data corresponding to “Song / Pattern Mode” from the nonvolatile memory 4 and storing it in the RAM 3, setting the receiving channel numbers in the registers BR and R1 to R16, and a plurality of data corresponding to the registers BR. There are specific part designations. In step S2, the reception channel number of the basic receive channel setting register BR and the associated part are changed according to the operation of the designated switch by the user. Thereby, the operation mode of the sound source in the performance state for parameter adjustment is determined. In step S3, the reception channel number of the reception channel setting registers R1 to R16 is changed according to the operation of the designated switch by the user. Thereby, the operation mode of the sound source in a normal performance state is determined. In step S4, the parameter adjustment mode is set according to the operation of the parameter adjustment on / off switch by the user.

  In step S5, it is determined whether or not the parameter adjustment on / off switch is set to on. If it is determined that the parameter adjustment on / off switch is set to ON (step S5: yes), the reception channel numbers of the plurality of specific parts P1 to P4 are associated with each other based on the basic receive channel setting register BR. At the same time, the data input is switched to MIDI data generated based on an external keyboard (external keyboard KB) operation (step S6). Then, it is determined whether or not the MIDI data generated by the external keyboard operation (specifically, a MIDI message) has been received (step S7). If it is determined that the MIDI data generated by the external keyboard operation has not been received (step S7: no), the process jumps to step S10. In this case, no musical tone is generated because the musical tone generation process is not executed. On the other hand, if it is determined that the MIDI data generated by the external keyboard operation has been received (yes in step S7), the channel designation (channel number) of the channel message included in the received MIDI data is also basic. It is determined whether or not it matches the reception channel number set in the receive channel setting register BR (step S8).

  If it is determined that the channel designation of the channel message does not match the reception channel number set in the register BR (No in step S8), it is not necessary to execute the tone generation process for the MIDI data designated by the channel. Therefore, this is ignored and the process jumps to step S10. If it is determined that the channel designation of the channel message matches the reception channel number set in the register BR (Yes in step S8), the plurality of specific parts P1 to P4 associated with the register BR are based on the MIDI data. Channel message processing (ie, musical tone generation processing) is executed (step S9). By a series of processing from step S6 to step S9, musical tone generation in a performance state for parameter adjustment (single sound source) is realized. In step S10, in accordance with the operation of the parameter setting switch by the user, the tone generation parameters specific to each part are changed with respect to parts P1 to P4 that operate as a single sound source and are generating tone. As a result, the tone generation parameters stored in the parameter storage unit K are rewritten.

  If it is determined in step S5 that the parameter adjustment on / off switch is set to off (no in step S5), the reception channel numbers of the parts P1 to P16 are determined based on the reception channel setting registers R1 to R16. And the data input is switched to the MIDI data generated when the sequencer SQ reproduces the song data and pattern data (step S11). Then, it is determined whether or not the MIDI data generated along with the data reproduction by the sequencer SQ is received from the sequencer SQ (step S12). If it is determined that the MIDI data generated during data reproduction has not been received (step S12: no), the process jumps to step S14. If it is determined that the MIDI data generated along with the data reproduction has been received (yes in step S12), the channel designation (channel number) of the channel message included in the received MIDI data among the parts P1 to P16 For the part (any one of P1 to P16) associated with the received channel number that coincides with the channel data, the channel message processing based on the MIDI data (that is, musical tone generation processing) is executed (step S13). By a series of processing from step S11 to step S13, musical tone generation in a normal performance state (multi sound source) is realized. In step S14, in accordance with the operation of the parameter setting switch by the user, the tone generation parameters specific to each part are changed with respect to the parts P1 to P16 that operate as a multi-sound source and are generating tone. As a result, the tone generation parameters stored in the parameter storage unit K are rewritten. In particular, the musical tone generation parameters specific to the parts P1 to P4 can be arbitrarily changed regardless of whether they are operating as a single sound source or as a multi sound source. The same setting value is maintained for the sound source.

  As described above, according to the present embodiment, according to the setting of the parameter adjustment mode, reception channel numbers associated with some specific parts among a plurality of parts previously associated with different reception channel numbers are stored. The common reception channel number stored in the means is changed. As a result, in the parameter adjustment mode, when performance data having a channel number that matches the common reception channel number is acquired, all of the part parts simultaneously start generating musical sounds based on the performance data. That is, in the present invention, even if the parameter adjustment mode is set, the sound source from the multi-sound source to the single sound source is not changed without changing the sound source setting data including not only the part configuration but also the memory configuration for generating the tone and the tone generation parameters. The function of can be changed temporarily. In this way, from the state where a plurality of parts are functioning as a multi-sound source, only a part is temporarily functioned as a single sound source, and during that time, the user can select a musical tone specific to each part with respect to the part part. Since the generation parameters can be adjusted, the user can easily adjust the parameters compared to the situation where multiple voices in a multi-sound source are played simultaneously. It can be easily reflected in the generation of musical sounds immediately and confirmed. In addition, the musical sound generated when using a single sound source is a thick musical sound in which different voices are stacked (that is, layered). This is a musical sound obtained by extracting several voices from the musical sound generated by a multi-sound source. Therefore, it becomes easy for the user to adjust the musical tone generation parameters for finishing the musical tone according to the image.

  Note that when performance data of other channel numbers is acquired in the parameter adjustment mode, a part having a corresponding reception channel number other than a part part may generate a musical tone. Specifically, in the flowchart shown in FIG. 3, when it is determined in step S8 that the channel designation of the channel message does not match the basic receive channel (no in step S8), the basic one of the sound source parts 1 to 16 is selected. For parts other than the part associated with the receive channel, the channel message is processed for the corresponding part according to the channel designation of the channel message that matches the reception channel number associated with each other part. (Musical tone generation processing) may be executed.

In the above-described embodiment, the musical sound is generated based on the MIDI data generated in response to the operation of the external keyboard KB in the parameter adjustment mode. However, the present invention is not limited to this. For example, a musical sound may be generated based on MIDI data generated by operating a performance operator provided in the musical sound generating device or based on a single single channel of MIDI data stored in advance. Good.
In the above-described embodiment, the normal performance state and the performance state for parameter adjustment are switched according to the on / off operation of the parameter adjustment on / off switch. Switching from the performance state to the normal performance state may be automatically performed after a predetermined time has elapsed since the on / off switch for parameter adjustment. Of course, it goes without saying that the user may arbitrarily set the elapsed time in such a case.

  Note that the musical sound generating device according to the present invention can be applied to an electronic musical instrument, as well as a sound source having a plurality of parts such as a karaoke device, a game device, a portable communication terminal such as a mobile phone, and an automatic performance piano. Needless to say, the present invention can be applied to any device or apparatus. Moreover, the structure of a personal computer and application software may be sufficient.

1 is a block diagram of a hardware configuration showing an embodiment of the overall configuration of a musical sound generating apparatus according to the present invention. It is a block diagram which shows typically one Example of the sound source which has several parts. It is a flowchart which shows one Example of a multi sound source process.
