Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a musical sound generator having a voice guiding function, and is applicable to electronic musical instruments and other musical sound generators.

[0002]

2. Description of the Related Art An electronic musical instrument having a voice guide function has been conventionally known, but the conventional musical instrument has a data structure of a normal musical tone based on a key pressing operation or the like and a data structure of a guide voice. In addition, a special voice generating circuit or processing for generating a guide voice is additionally required. Typically, it has been considered that the guide voice is generated by a phonological synthesis technique. That is, a plurality of phonemes constituting a series of words corresponding to a desired guide description are designated by sequence data, and each phoneme is combined in a time series according to the sequence data, so that an example guide voice is synthesized. I have. In this case, interpolation is used to smooth the connection between the phonemes. On the other hand, the generation of normal musical tones (scale tones) does not use such a phonological synthesis technique. For example, a waveform memory readout and its readout output are performed by a combination of timbre instruction data and control data such as an envelope. By performing the above-described arithmetic processing, a tone signal having a desired tone color, envelope characteristics, and the like is generated.

[0003]

As described above, in the prior art, since the data structure of the normal tone and the data structure of the guide voice are different, a special voice generation module for generating the guide voice is added. And the configuration becomes complicated. In particular, in the case of generating a guide voice by a phoneme sequence reproduction process, the load on the CPU is correspondingly large. In addition, since two tone generation channels need to generate sound signals of successive phonemes in parallel for interpolation calculation during phoneme synthesis, the tone generation channel is occupied extra. There are points. A polite voice guide is preferred for beginners, but may be noisy for those who are already familiar with instrument operation, especially when the generation of normal musical sounds and the generation of guide voices overlap. In such a case, there is a possibility that both will be difficult to hear, so improvement is desired.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has as its object to provide a musical sound generating apparatus having a voice guiding function with a simple configuration. It is another object of the present invention to provide a tone generator capable of taking effective countermeasures when the occurrence of a normal tone and the occurrence of a guide sound overlap.

[0005]

According to the present invention, there is provided a musical tone generating apparatus comprising: data storing means for storing musical tone data corresponding to a tone color and predetermined guide voice data in the same data structure; A control means for generating guide voice instruction information for instructing a guide voice to be generated in accordance with an operation or an operation state of the apparatus; and a tone instruction for instructing a tone to be generated having a plurality of tone generation channels. The tone data is read from the data storage means in accordance with information, a tone is generated based on the tone data in one of the channels, and the guide voice is generated in accordance with the guide voice instruction information generated by the control means. Musical tone generating means for reading data from the data storage means and generating a guide voice based on the guide voice data on any channel. .

According to the present invention, since the tone data corresponding to the timbre and the guide voice data have the same data structure, a special voice generation module for generating the guide voice is not required, and a common tone generation is performed. It is possible to generate a musical tone based on the musical tone data and a guide voice based on the guide voice data by using the means, thereby simplifying the configuration. Accordingly, a sequence reproduction process such as phonemic synthesis is not required, so that the configuration can be simplified. Further, since interpolation processing using two channels as in phonemic synthesis is not required, the configuration can be simplified accordingly, and the musical tone generating channel is not occupied extra. .

Further, according to the present invention, a guide mode selecting means for selecting one of a plurality of guide modes, and at least one of a musical tone and a guide voice generated by the musical tone signal generating means in accordance with the selected guide mode. Is provided. For example, one of a plurality of guide modes is selected according to the user's grade, such as beginner, intermediate, advanced, etc. In the guide mode for beginners, the generation of normal musical sounds and the generation of guide sounds are performed. In the case of overlapping, the volume of the normal musical sound is lowered to make the guide voice easier to hear, while in the guide mode for the intermediate level, the occurrence of the normal musical sound and the generation of the guide sound overlap. In this case, by taking into account the relationship between the musical sound and the guide sound that are simultaneously generated, for example, by giving control such as not generating the guide sound or suppressing the volume of the guide sound, giving priority to the generation of normal musical sounds. Thus, sound control can be performed in various forms. Alternatively, the generation form of the guide voice may be appropriately controlled in accordance with the selected guide mode without considering the existence of musical tones that are generated simultaneously.

Done.

FIG. 3 is a diagram showing an example of a data storage unit for storing musical tone data corresponding to each tone (voice) and guide voice data corresponding to each guide voice. The data storage unit may use any of the RAM 11, the ROM 12, the hard disk 13, and the external storage device 14. In this data storage unit, as shown in the figure, musical sound data corresponding to various timbres (voices) such as piano, brass, strings, etc., and guide voice 1, guide voice 2,
Guide voice data corresponding to various guide voices such as the guide voice 3 and the guide voice 4 are stored in the same data structure. For example, assuming that the musical tone data for the piano tone comprises waveform data of the piano tone and various parameter data for controlling the volume envelope and the like, the guide sound data for the guide sound 1 is It is composed of waveform data indicating a series of sounds and various parameter data for controlling the volume envelope and the like. That is, a data structure in which each guide voice is treated as a kind of tone (voice) (an individual tone color number is assigned to each guide voice) means "the same data structure". is there. Here, it has been described that the waveform data and the parameter data are stored together for each tone color and each guide voice in one data storage unit. However, the present invention is not limited to this. Parameter data for each tone and for each guide voice,
Specific waveform data (PCM waveform data or ADP
Waveform data in an appropriate data format such as CM waveform data) may be stored in a separate waveform data storage unit and read out in accordance with the waveform instruction data (tone color number instruction data). In this case, it is also possible to use common waveform data between different timbres and make the timbre characteristics different according to the parameter data. Note that the coding format of the waveform data itself may be the same for the normal tone and the guide voice, or may be different as appropriate. For example, the waveform data of the normal tone may be stored as PCM waveform data, and the waveform data of the guide voice may be stored in an appropriately compressed form such as ADPCM or the like. Also, the tone synthesis method can be appropriately changed between the normal tone and the guide voice. For example, a normal musical tone can be filtered or F
While appropriate processing such as M musical sound synthesis processing is performed, the guide voice may have a difference such that the audio signal is simply reproduced according to the read waveform data.

Here, an example of the contents of the guide voice will be described. The guide voice includes various types of guide voices, such as a guide voice explaining a function of a certain control element when the input device 16 is operated by the input device 16 and a guide voice explaining a current operation state according to progress of subsequent processing. There may be things. For example, when the voice switch 161 is operated once, the guide voice 1 emits a message “switch to voice mode”. The guide voice 2 is for issuing a message “switched to voice mode” when the voice switch 161 is operated again. In addition, the guide voice 3 is thereafter displayed, "The numeric keypad is currently used for tone selection."
Is issued. The guide voice 4 is a message that, when the REC switch 164 is operated in the voice mode, a message "The REC switch does not work in the voice mode. Please switch to the song mode." As described above, various guide sounds are selectively generated in accordance with the functions of the controls on the input device 16 and the current operation state.

Further, the timbre characteristics of the voice sounds used for each guide voice may be common, or may be appropriately varied such as male voice, female voice, soprano, alto, tenor, baritone, etc. You may do so. For example, all guide voices related to the voice mode may be set as male voices, and all guide voices related to the song mode may be set as female voices. This is convenient because the current mode can be immediately determined according to whether the guide voice is a male voice or a female voice.

Further, since the guide voice data has the same data structure as the tone data of a normal tone color, it can be assigned to an arbitrary tone generating channel and sounded.
In addition, since parameter data is included, when sound generation processing is performed by allocating to a tone generation channel, the volume envelope and the like of the parameter data are arbitrarily controlled by setting or changing the parameter data, thereby changing the generation form of the guide voice. Variable control over time is possible. For example, if the beginner's guide mode is selected as the guide mode of the system, control is performed so that all guide voices are pronounced to the end, while if the intermediate guide mode is selected, the guide voice pronunciation is performed. It is possible to perform control such as omitting the remaining sound generation by appropriately lowering the sound volume level during the operation, and canceling all guide sounds when the advanced guide mode is selected. Also,
As will be described later, this control may be performed in consideration of a relationship with a normal musical tone that is generated simultaneously. The processing load of the CPU 10 can be appropriately reduced by such different control modes according to the plurality of guide modes.

FIG. 4 is a flowchart showing the case of the "normal guide process" as an example of the guide voice generation process.
This “normal guide processing” indicates a basic guide processing example. First, when the input device 16 detects that a predetermined operator is operated (step S1), a guide voice explaining a function corresponding to the operated operator is selected (step S2). That is, guide voice instruction information for instructing a guide voice to be generated is generated according to an operation of a predetermined operation element. For example, when the voice switch 161 is operated, guide voice instruction information for instructing the guide voice 1 is generated.

Next, predetermined guide voice data is read out from the data storage unit (FIG. 3) in accordance with the guide voice instruction information generated in the previous step S2, and the guide voice data is subjected to a process of generating the guide voice. It is given to the sound source device 18 together with the channel instruction information indicating the channel to be performed (step S3). Accordingly, in the sound source device 18,
A guide voice based on the guide voice data is generated on the designated channel. Note that the guide voice data provided to the sound source device 18 may be timbre waveform instruction data and parameter data instead of the entire timbre waveform data and parameter data. The sound source device 18 sequentially reads out the timbre waveform data designated by the timbre waveform instruction data, that is, the guide voice waveform data from the data storage unit with the progress of the sound generation process, and thereby generates a predetermined guide voice. . Here, when controlling the volume or the like of the guide voice according to the selected guide mode,
The parameter data included in the guide voice data is set so that such control can be performed. For example, when the elementary guide mode is selected, the setting parameter data of the volume envelope included in the guide audio data is set so as to generate all necessary envelopes. Alternatively, when the volume of the guide voice is suppressed from the middle, the setting parameter data of the volume envelope included in the guide voice data is set to such content. The setting of such parameter data may be automatically performed in conjunction with the selection of the guide mode.
It should be noted that it is convenient to allocate the channel for generating the guide voice from the available channels as appropriate, since the channel can be used efficiently. However, the present invention is not limited thereto, and a predetermined dedicated channel may be used as a channel for generating a guide sound. When the sound source device 18 is a software sound source, the process in step S3 includes a process of passing guide voice data and channel instruction information to the software sound source program. In response to this, the software sound source program
The timbre waveform data designated by the timbre waveform instruction data, that is, the guide voice waveform data, is sequentially read from the data storage unit with the progress of the tone generation process, whereby a predetermined guide voice is generated.

Next, in step S4, the process waits for a predetermined time (for example, about 5 to 10 seconds), and it is checked whether or not the same operator has been operated again during this wait time. YE
If it is S, a predetermined process reflecting the operation on the operated operator is performed (step S5). That is, in accordance with the first operation of the operator, a guide voice generation process for explaining the function of the operator is performed (steps S2 and S3).
If the same operator is operated once more within the predetermined time,
An original process reflecting the operation of the operator is performed (step S5). For example, if the operator is a voice switch 1
If it is 61, the voice mode is set here. next,
A guide voice that describes an operation state changed or set in accordance with the operation of the operator is selected (step S
6). That is, guide voice instruction information for instructing a guide voice to be generated is generated according to the operation of the operation element. For example, when the voice switch 161 is operated for the second time, guide voice instruction information for instructing the guide voice 2 to explain switching to the voice mode is generated.

Next, in step S7, the step S
As in the case of No. 3, predetermined guide voice data is read from the data storage unit (FIG. 3) in accordance with the guide voice instruction information generated in the previous step S6, and the guide voice data is subjected to a process of generating the guide voice. It is given to the sound source device 18 together with the channel instruction information for instructing the power channel (step S7). In response to this, the sound source device 18 generates a guide voice based on the guide voice data in the specified channel. On the other hand, if the same operator is not operated again within the predetermined time, step S4 branches to NO, returns to the process, and ends this processing. In this case, only the guide voice explaining the function of the operator is produced. By the way, during the waiting time in step S4, it may be displayed on the display 17 that the operator is waiting for input of an operator, or may be notified by a predetermined guide sound. Further, the length of the waiting time in step S4 may be appropriately changed according to the guide mode.

The processing executed by the CPU 10 is not limited to the processing shown in FIG. 4, but may be any other known processing. For example, when a key is pressed on the keyboard 15, musical tone instruction information corresponding to the pressed key is generated, and based on this, the generation of the musical tone corresponding to the pressed key is assigned to an appropriate musical tone generating channel. The tone data of the tone corresponding to the pressed key is read from the data storage unit (FIG. 3).
Based on the musical tone data, a musical tone corresponding to the pressed key is generated on the channel of the sound source device 18. When a desired song is selected and the automatic performance of the song is performed, performance data corresponding to the song (namely, musical tone instruction information for instructing a musical tone to be generated) is read out from an appropriate memory, and read out from the appropriate memory. Similarly, an appropriate tone generation channel is assigned, and based on this, a tone corresponding to the performance data (tone instruction information) is assigned to an appropriate tone generation channel, and the performance data (tone instruction information) is also assigned. The tone data of the tone is read from the data storage unit (FIG. 3),
A tone corresponding to the performance data is generated on the channel of the tone generator 18 based on the tone data.

Next, an embodiment in which one of a plurality of guide modes can be selected according to the grade of the user will be described. For example, selectable guide modes include advanced guide mode, intermediate guide mode, beginner guide mode,
It is assumed that there are three. For example, the advanced guide mode is a mode for canceling all voice guides. When the advanced guide mode is selected, the operation immediately reflects the operation of the operator when the operator is operated by the input device 16 without performing the normal guide process of FIG.
5).

For example, the intermediate guide mode is a mode in which a voice guide is provided, and the voice guide is appropriately suppressed so that the musical performance has priority over the voice guide. For example, if an instruction to generate a normal musical tone is issued during the generation of a guide voice, the guide voice is cut or suppressed in volume from the middle so as not to disturb the generation of the normal musical tone. Alternatively, when a certain operation element is operated during the generation of the normal musical sound to give an instruction to generate a guide sound, the generation of the guide sound explaining the function of the operation element is canceled, and the operation of the operation element is immediately performed. Perform the process to reflect. Alternatively, irrespective of whether or not normal musical tones are simultaneously generated, in this intermediate guide mode, only a guide voice for explaining the function of the operated operator is generated, and no guide voice for explaining the operation state is generated. For example, only some of the guide sounds may be generated.

For example, the elementary guide mode is a mode in which a necessary voice guide is always provided so that the voice guide is prioritized to a normal musical performance, and the volume of the normal musical sound is appropriately suppressed while the voice guide is sounding. For example, if an instruction to generate a normal tone is issued during the generation of the guide sound, the volume of the normal tone is suppressed so that the guide sound can be easily heard. Alternatively, when a certain operation element is operated during the generation of a normal musical tone and an instruction to generate a guide voice is issued, a guide voice that describes the function of the control element is generated, so that the guide voice can be easily heard. , Usually suppresses the volume of musical sounds.

FIG. 5 is a flowchart showing an example of how the control is performed in association with a normal musical tone performance when the intermediate guide mode is selected. First, when it is detected that an operation element is operated on the input device 16 (step S10), it is checked whether or not a musical tone is being generated (step S11). Execute voice guidance processing. The contents of the voice guide processing in step S12 are the same as those in steps S2 to S2 of the "normal guide processing" shown in FIG.
The processing may be substantially the same as S7. If a musical tone is being generated, the process proceeds to step S13, and processing for immediately reflecting the operation of the operation element is performed. In this case, the generation of the guide voice is canceled, and the tone of the musical tone being generated in the normal form is maintained.

On the other hand, when an operation for instructing the generation of a normal tone, such as the detection of a key depression on the keyboard 15 or the detection of a song start operation, is performed (step S14), it is determined whether any guide voice is being generated. Is checked (step S15). If YES, the sounding guide voice is dumped midway (to zero volume) and the sounding of the guide voice is canceled (step S16). After that, a normal tone generation process is performed based on the key press detection or the song start operation detection (step S1).
7). Of course, if the guide voice is not being generated, step S
From NO of 15 immediately goes to step S17. As described above, the known musical tone generation processing may appropriately adopt a known configuration, and thus the details of step S17 are not particularly described.
As described above, in the intermediate guide mode, the tone generation processing of the normal musical tone has priority over the pronunciation of the guide voice.

FIG. 6 is a flow chart showing an example of how the control is performed in association with a normal tone performance when the elementary guide mode is selected. 6, steps S20, S21, and S22 are the same processes as steps S10, S11, and S12 in FIG. In this case, when a musical tone is not being generated when the operation element is operated on the input device 16, the process goes to step S22 to execute a voice guide process. On the other hand, if a musical tone is being generated when the operator is operated on the input device 16, the process goes to step S23, and the volume of the musical tone being generated is set to, for example, 6 to 12d.
After lowering by about B, a predetermined voice guide process is started. The contents of the voice guide processing in step S23 are also the same as those in FIG.
May be substantially the same as steps S2 to S7 of the “normal guide processing” shown in FIG. However, in step S23, the volume of the musical tone being generated is immediately raised by, for example, about 6 to 12 dB to return to the original volume when the sound of the guide voice ends.

In FIG. 6, steps S24, S25,
S27 is a process similar to steps S14, S15, and S17 in FIG. In this case, when an operation for instructing the generation of a normal musical tone is performed (step S24), unless any guide voice is being generated (step S25).
NO), the normal tone generation start process is immediately performed (step S27). On the other hand, if any guide voice is being generated (YES in step S25), the flow proceeds to step S26, and the volume of the musical tone to be generated is set to, for example, 6-1.
The tone generation process of the musical tone is performed by lowering the tone by about 2 dB. When the sounding of the sounding guide sound is completed, the sound volume of the tone being generated is immediately raised by, for example, about 6 to 12 dB and returned to the original sound volume. When the tone generation start process is performed in step S26, the channel in which the guide sound is being generated may not be included in the target of the truncation process in the process of assigning the channel in which the tone is to be generated. Thus, when all the channels are busy (assigned), when the assigned channel corresponding to the oldest operated key is truncated and a new musical tone is assigned to the truncated channel, the channel that is generating the guide sound is By not being included in the target of the truncation processing, the guide voice can be reliably emitted to the end. Thus, in the elementary guide mode, the pronunciation of the guide voice has priority over the pronunciation of the normal musical tone. Therefore, the guide voice is easy to hear.

The guide mode may not be selected and set in common for the entire system, but may be selected for each operation element. Also, an arbitrary guide mode may be selected and set for each operation mode such as a voice mode, a song mode, an edit mode, and a rec mode. For example, in the voice mode related to the voice switch 161, the intermediate guide mode may be selected and set, and in the edit mode related to the edit switch 165, the beginner guide mode may be selected and set. In addition, the number of times each operation element is operated in the input device 16 is stored in a non-volatile memory, and a guide mode for each operation element or each operation mode is automatically selected according to the number of times. It may be. Furthermore, the present invention can be constructed and implemented not only as an apparatus invention, but also as a method invention, and further includes a software program for executing such a method on a computer or a processor. The invention may be configured and implemented as an invention of a stored storage medium.

[0028]

As described above, according to the present invention, since the tone data corresponding to the timbre and the guide voice data have the same data structure, a special voice generation module for generating the guide voice is required. In addition, it is possible to generate a musical tone based on the musical tone data and a guide voice based on the guide voice data using a common musical tone generating means, thereby simplifying the configuration. Accordingly, a sequence reproduction process such as phonemic synthesis is not required, so that the configuration can be simplified. Further, since interpolation processing using two channels as in phonemic synthesis is not required, the configuration can be simplified accordingly, and the musical tone generating channel is not occupied extra. .

Further, according to the present invention, a guide mode selecting means for selecting one of a plurality of guide modes, and at least one of a tone generated by the tone signal generating means and a guide voice in accordance with the selected guide mode. For example, in the guide mode for beginners, if the generation of a normal musical tone and the generation of a guide voice overlap each other, the volume of the normal musical sound is reduced, and While making the voice easier to hear, in the guide mode for intermediate users, if the generation of normal musical sounds and the generation of the guide voice overlap, the generation of the guide voice is not performed or the volume of the guide voice is suppressed. By taking into account the relationship between the musical sound and the guide sound that are simultaneously generated, for example, by giving priority to the generation of normal musical sound, It is possible to perform the sound control. Alternatively, it is also possible to appropriately control the generation form of the guide voice according to the selected guide mode without considering the presence of musical tones that are simultaneously generated.
