(3) post-effect signal SE from the effect circuit 25
There are three types.

  Here, the input signals SM and ST are selectively output from the MIX 27 to the effect circuit 25 to give an effect, and the signals SM and ST output for giving an effect in this way are the terminal system TS main body. Is selectively set by operating a predetermined switch in the operation element 12 of FIG. The MIX 27 can output all the synthesized signals to a digital-to-analog converter (DAC) 28 and also output digital signals via the digital output terminal 18.

  The DAC 28, the amplitude control circuit (VOL) 29, and the amplifier circuit (AMP) 30 constitute an analog output device. The analog musical tone signal output from the DAC 28 has its volume adjusted by the VOL 29 and is output to the audio control circuit 7 of the terminal system TS via a headphone terminal, or transmitted to the sounding speaker 17 via the AMP 30 to generate a musical tone. It is emitted as That is, all of the synthesized signals are output from the VOL 29 to the audio control circuit 7 as analog signals, and are also supplied from the AMP 30 to the speakers 17 as analog signals and emitted as musical sounds.

[Sound control circuit (2)]
FIG. 3 is a block diagram showing a detailed configuration of a tone control circuit according to another embodiment of the present invention. In this example, the tone control circuit 8 includes a tone control CPU 31 in the circuit, and can control the operation of the tone control circuit 8 independently of the main CPU 1. A sound control CPU 31, a communication circuit 32, a timer 33, a sound control ROM 34, a sound control RAM 35, a sound source circuit 36, an effect circuit 37, a mixer circuit (MIX) 38, an amplitude control circuit (VOL) 39, and the like. Reference numerals 39 are connected to each other via a sound control circuit bus (sound control BUS) 40.

The communication circuit 32 has the following two communication functions:
(1) “Perform bidirectional information communication with the main unit BUS11” = Music information, performance information, setting information, and the like received from outside the terminal system TS via the main unit BUS11 and the communication circuit 32; (Note that the sound control ROM 34 stores various tables and the like for sound control.) Further, it receives various information (operation information of the main body operation elements) relating to selection of tone color and effect, parameter change, selection of music information to be reproduced, and the like. The received information is interpreted by the operation of the tone generation control CPU 31, and processing corresponding to each information, for example, setting relating to the selected timbre is performed for the tone generator circuit 36 (corresponding to the timbre selected from the ROM 34 or the RAM 35). The setting information is read out and output to the tone generator circuit 36).

  When an operation of the main body operator is instructed to edit music information or setting information recorded in the sound control ROM 34 or the sound control RAM 35 in the sound control circuit, the operation is controlled from the ROM 34 or the RAM 35. The information to be performed (selected) is read out and transmitted to the main body RAM 3 (the editing processing is performed using the main body RAM 3, and when the editing processing is completed, the information is again overwritten in the RAM 35 in the tone generation control circuit). .

(2) "Perform bidirectional communication of information with the audio control circuit 7" = a tone signal or the like synthesized inside the tone generation control circuit 8 is transmitted to the audio control circuit 7 or a call sound signal received from the audio control circuit 7 Processing such as processing the signals in the sound control circuit 8 and transmitting the processed signals to the audio control circuit 7 again is performed. The processing described above includes, for example, an effect imparting process to the call sound and a pitch / tone conversion process of the call voice.

  The tone control CPU 31 controls the operation of the tone control circuit 8 independently of the terminal system TS main body, and performs the performance stored in the tone control ROM 34 and the tone control RAM 35 based on the signal generated from the timer 33. By sequentially reading the information, a tone such as an incoming melody or BGM is reproduced. The sound control CPU 31 transmits the setting information in the sound control ROM 34 and the sound control RAM 35 to the tone generator circuit 36 and the effect circuit 37 via the sound control BUS 40 for reproduction, and further sets the tone color of the musical sound and the effect to be applied. Can also be controlled. The process of starting and ending the performance of a musical tone is started based on an instruction operation using the operation unit 12 of the main body.

  The timer 33 generates a signal every predetermined time. Based on the signal generated here, the tone generation timing of a tone such as a ringtone melody tone or a BGM tone is controlled, and the performance tempo of the tone generated is determined. This tempo can be controlled by the user.

  The way of controlling the tempo may be any. For example, a method of changing the cycle of the signal generated from the timer 33 in accordance with the set tempo (that is, changing the processing cycle of the music information), and setting the processing cycle (the cycle of the signal from the timer 33) to be constant The method of changing the value of the timing data in the information according to the set tempo, the method of counting the timing data in the music information in one process by keeping the processing cycle (the cycle of the signal from the timer 33) constant. For example, there is a method of changing according to. The user can specify the tempo by specifying the absolute value of the tempo (eg, “120” or “150”), by specifying the tempo slogan (“allegro”, “moderate”, etc.), or by changing from the reference tempo (percent ( %), An increase / decrease value (±)], and an intuitive term (“fast”, “slow”, “medium”, etc.). These are designated using the operation unit 12 of the main body.

  The sound control ROM 34 stores a plurality of predetermined pieces of music information, performance information, setting information, a conversion table for information format conversion, and a plurality of compression tables for information compression for incoming melody, BGM, and the like. In addition, a plurality of pieces of music information, performance information, and setting information that have been added or newly created can be stored.

  The sound source circuit 36 is an FM sound source in this example, and is capable of simultaneously generating a plurality of sounds. A tone tone is set based on tone-related setting information transmitted from the tone control ROM 34 and the tone control RAM 35 via the tone control BUS 40. Under the control of the tone generation control CPU 31 and the timer 33, the tone generator circuit 36 sequentially synthesizes tone signals corresponding to the set timbres based on performance information transmitted from the tone generation control ROM 34 and the tone generation control RAM 35, and MIX 38 Output to

  The effect circuit 37 sets the effect to be applied to the musical tone based on the setting information on the effect transmitted from the sound control ROM 34 and the sound control RAM 35 via the sound control BUS 40. The effect circuit 37 also applies an effect to the signal input from the MIX 38 and the speech sound signal ST input from the communication circuit 32, and outputs the signal SE after the addition to the MIX 38 again.

The MIX 38 sums the input signals and outputs the sum to a digital-to-analog conversion circuit (DAC) 41 and the digital output terminal 18. The signals input to the MIX 38 include:
(1) Synthesized tone signal SM from tone generator circuit 36,
(2) a call sound signal ST from the audio control circuit 7;
(3) The post-effect signal SE from the effect circuit 37
and so on. The MIX 38 selectively outputs the input signals SM and ST to the effect circuit 37 in order to give an effect, and the output signal is set by operating a predetermined switch of the operation unit 12 on the terminal system TS main body side.

  The amplitude control circuit (VOL) 39 and the amplifier circuit (AMP) 42 constitute an analog output device. The volume of the analog tone signal output from the DAC 41 is adjusted by the VOL 39, and the adjusted analog tone signal is output from the headphone terminal. The signal is output to the audio control circuit 7 and further transmitted to the sounding speaker 17 via the AMP 42.

[Terminal system usage environment]
FIG. 4 is a conceptual diagram showing an example of a usage environment of the portable telephone terminal according to one embodiment of the present invention. In the first environment, a call is made from a portable telephone terminal (terminal system) TS used by a user to a base station (server station) BS via a transmission / reception circuit 6 to select desired music information and request transmission thereof. The corresponding music information or the like is transmitted from the base station BS, downloaded into the terminal system TS, and using this information, a melody sound at the time of an incoming call or a BGM sound during a call can be generated.

  In the second environment, the terminal system TS receives music information or the like created by the personal computer terminal PC via the communication cable 20 connected to the communication I / F 10 and uses the information as a melody or BGM. Can be.

  Further, in the third environment, the terminal system TS introduces music information and the like recorded on the small external recording medium 19 attached to the connection circuit 9 from the recording medium 19, and in the fourth environment, other music information is introduced. Music information of another telephone terminal OS is received from the telephone terminal OS via the telephone line and the transmission / reception circuit 6 via the base station BS, or via the communication cable 20 and the communication I / F 10. Information can be used for musical sound pronunciation.

  The music information introduced into the terminal system TS from music information sources such as the base station BS, the personal computer terminal PC, the external storage medium 19, or another telephone terminal OS can be edited in the information sources BS, PC and the system TS. Downsized to a usable form by compression, format conversion, etc.

  For example, the music information (including performance information and setting information) introduced into the terminal system TS from these music information sources may be in a format suitable for the own model or in another format. When a format suitable for the own model is introduced, it is created in advance in this format or converted from another format (format conversion). This format conversion is performed by the base station BS or personal computer. This is performed in the computer terminal PC. When another format is introduced to the terminal system TS, the other format is converted into the format of the terminal system TS in the terminal system TS.

[Information format]
FIG. 5 shows an example of the information format of its own model in the portable telephone terminal according to one embodiment of the present invention. As shown in FIG. 5, the “music information IA corresponding to the own model” that can be handled by the portable telephone terminal system TS and another telephone terminal of the same model that performs information processing in the same format as the terminal system TS, as shown in FIG. It is composed of setting information SA for setting timbre / effect and performance information MA for musical performance. Each of the information SA and MA records only the minimum necessary information so that the storage capacity of the memory (RAM3) in the terminal system is not squeezed and a better tone can be produced. In the terminal system TS, sound generation control is performed according to the information. Hereinafter, this type of information format is referred to as “own model format A”.

The setting information SA relates to a tone color.
(1) Tone number NA for identifying a tone type,
(2) Detailed information (tone color parameter) DA for setting the tone in the tone generator circuit
Includes The timbre parameter DA of (2) includes algorithm data AA, frequency parameter (F parameter) FA, envelope parameter (EG parameter) EA, and the like.

  The algorithm data AA is a parameter for determining a combination, that is, an algorithm, of a plurality of operators (sine wave memory + output level calculator + envelope (EG) waveform synthesizer set) in the FM sound source. The EG parameter EA is a parameter for determining the frequency of the read sine wave for each operator, and the EG parameter EA is a parameter for setting a plurality of level values and rate values for synthesizing an envelope waveform (EG waveform). .

  The setting information SA includes information for setting effect parameters, an effect program (DSP program) for determining the contents of the effect circuit 25, voice information, image information, and the like, in addition to the tone color setting information NA and DA. There is.

  The performance information MA is information for performing the performance including the timing data TM, the key number KN, the gate time GT, and the like, and is recorded in the performance order.

  FIG. 6 shows an example of a conventional information format in a portable telephone terminal of another model. The conventional type of music information IB used as ringing melody information in the portable telephone terminal is, as shown in FIG. 6, only performance information represented by a symbol string composed of symbols a, b, c,. No configuration information exists. Hereinafter, this type of information format is referred to as “conventional format B”.

  More specifically, the performance information IB of the other models includes symbols (#, 1, 2, 3,...) That can be input using numeric keys provided on the portable telephone terminal in the order of playing the music in accordance with a predetermined rule. They are arranged. For example, the numeral “1” corresponds to the pitch of “do”, the numeral “2” corresponds to the pitch of “re”,... Stipulate. Therefore, when “1-1-2-1-1-1...” Is represented by the symbol strings “a”, “b”, “c”,... Represents a musical tone in which "" is pronounced in eighth note length and then "do" is again pronounced in quarter note length.

  FIG. 7 shows an example of a general-purpose tone information format conventionally used in electronic musical instruments and the like. In a conventional electronic musical instrument or the like, as shown in FIG. 7, setting information SC for setting timbres / effects and performance for musical tone performance are used in accordance with a general tone information format (“SMF” (Standard MIDI File) format). A tone information IC composed of information MC is used. Hereinafter, this type of information format is referred to as “SMF format C”.

The information for setting the tone in the setting information SC is:
(1) Tone number NC as timbre identification information;
(2) Detailed information for tone setting (tone parameter) DC
It is composed of

  As shown in FIG. 7, the timbre setting detailed information DC of (2) has a large amount of information unlike the timbre parameter DA for the terminal system TS. For example, in addition to the algorithm data AC and the F parameter FC, rate scale data RS for controlling the level of the EG according to the pitch at which the sound is generated is stored. The content of the EG parameter EC also includes more detailed information. Thus, the number of level values and rate values is larger than the number of EG parameters EA in the setting information SA in the format A of the own model of FIG. In the system including the terminal system TS, such excess information in the detailed information DC is compressed as information that is not indispensable in the terminal system TS when the format is converted from the SMF format C to the own model format A. (Deleted).

  The performance information MC is information of the “duration DR + event IV” format, and the key-on and key-off events are stored together with the duration data DR, so the amount of information is slightly larger. Also, velocity data is recorded for each key-on, and this velocity data is also compressed (deleted) at the time of format conversion to the format A of the own device.

  Note that the music information IC of FIG. 7 and the music information IA of FIG. 5 are described as a one-part configuration, but this is for convenience of explanation, and the music information IC and IA have a multi-part configuration. Is normal. In that case, only one setting information may be recorded for all parts.

[Information exchange with base station]
FIGS. 8 and 9 are functional block diagrams showing the information transfer relationship in the first system including the terminal system and the base station according to one embodiment of the present invention. According to the present invention, the own terminal, that is, the portable telephone terminal system TS receives music information and setting information from the base station BS. When the information is requested, the base station BS converts the format as necessary and receives the information. Sometimes, the information is used in the terminal system TS.

  First, the terminal system TS calls the base station (server station) BS via the transmission / reception circuit 6 by the request information transmitting module (S1), and responds to information in the database DB of the server station BS according to a predetermined instruction. Request download. Specifically, for example, during a call with the server station BS, music information, performance information, setting information, and the like stored in the database DB are sequentially displayed on the display unit 13 of the own terminal system TS. By inputting a number corresponding to any of these pieces of information using a key, and performing a request determination operation, selection information indicating the download target information to be requested, and the model / device number of the own terminal system TS and the terminal The identification information indicating the type of the sound source provided in the sound source circuit 24 of the system TS is transmitted to the server station BS.

  In the server station BS, in response to the transmission of the request information from the terminal system TS, music information corresponding to the request information is selectively read from the database DB by the selective reading module (B1). The format type of the output performance information and the like is determined by a determination module (not shown). Specifically, this determination is to check the contents of the format type information (not shown, but information indicating the format type of the information) attached to the read information. Then, the format type is determined, or when the format type information is not attached, the format type is determined from the content of the read information. As a result of this determination, if the format type of the read information is the format A of the own model, the format conversion (format conversion) is unnecessary, so that the information is immediately passed to the charging module (B2). On the other hand, if the read performance information or the like is in a format different from that of its own model, such as the conventional format B, it is sent to the charging module (B2) via the setting information attachment module (B3) and the format conversion module (B4). Handed over.

In the setting information attachment module (B3), if the read performance information in a format different from the own model does not have the setting information, for example, information of the conventional format B, the setting information is Attach. By attaching the setting information, even in the case of performance information of another model having no setting information, the terminal system TS can reproduce a musical tone with an effective tone / effect by utilizing the sound source function. Become. For setting information attachment method,
(1) Attach predetermined setting information,
(2) Attach setting information of user selection,
(3) There is a method of automatically detecting and attaching setting information adapted to the performance information.

  The performance information to which the setting information is attached is passed to the format conversion module (B4), and the format conversion to the format A of the own model is automatically performed by using a conversion table TB prepared in advance. This conversion table TB is prepared for each format combination before and after format conversion. For example, the conversion table TB is a table in which conversion rules from the conventional format B to the format A of the own model are described. The format conversion is performed from the format (B) to the format A of the own device.

  Although not shown in FIG. 9 as the format of another model, there is a case where the SMF format C is used in addition to the conventional format B. For example, when information of the SMF format C is read, The format conversion is performed using the conversion rule from the SMF format C in the conversion table TB to the format A of the own device. Therefore, even if the requested information is of another model (B, C, etc.), the format conversion function converts the requested information into music information IA that can be reproduced by the own terminal system TS, and uses the information in the terminal system TS. Enable.

  In the case of conversion from the SMF format C to the format A of the own model, the information compression module (P4) shown in FIG. 10 described later performs information compression before the format conversion described here. It is also possible to do.

  Thereafter, the charging module (B2) performs a charging operation for the download. In this work, by referring to the identification information (terminal model / device number, sound source type) transmitted from the terminal system TS, a specific contract is made with a specific model or a specific sound source device (a server station or the like). (E.g., a model or a sound source device), the charge amount is discounted when the terminal is recognized.

  After the charging operation, the server station BS transmits music information and setting information of its own model format A corresponding to the selection information from the terminal system TS to the system TS by the information transmission module (B5).

  On the other hand, in the terminal system TS, the information receiving module (S2) receives and downloads music information and setting information from the server station BS via the transmission / reception circuit 6, and the downloaded information is stored in the main body RAM3. Here, the terminal system TS may be in a call state from when the request is transmitted by the request information transmission module (S1) to when the information corresponding to the request is completely transmitted from the base station BS. Alternatively, the call may be temporarily released after the request information is transmitted, and the requested information may be received by a subsequent call process (e-mail or return call from the base station BS).

  Then, in the setting module (S3), a setting is made by the user's setting operation so that the incoming melody can be pronounced based on the received music information. Further, the received information can be set to be reproduced as BGM at the time of a call, music at any time, or the like.

  Note that the received music information and setting information may be automatically set as a ringtone melody sound or BGM sound immediately after reception, or at the time of reception (including the meaning of confirming reception information), Is preferably reproduced.

  In the system described so far, the base station BS side is configured to attach setting information and format conversion (and information compression) to music information, performance information, and setting information. Like the processing in the TS, the terminal system TS may perform setting information attachment, format conversion, and information compression.

[Information exchange with personal computer]
FIG. 10 is a functional block diagram showing an information transfer relationship in a second system including a terminal system and a personal computer according to one embodiment of the present invention. According to the present invention, the terminal itself, that is, the portable telephone terminal system TS can receive the music information and the setting information created on the personal computer terminal PC, and can use such information. Music information and setting information can be created in any format. For example, for the reason that the operability is good, it can be created according to the conventional SMF format C. When the music information and the setting information are created in a format different from the format A of the own device, the personal computer can be created at the time of transmission. The format conversion (format conversion) to the own model format A is performed on the terminal PC.

  In the personal computer terminal PC, by using the installed predetermined software, the selective reading module (P1) converts the data from the database DP in the computer terminal PC in which the information is recorded in the SMF format C or the own format A. When music information or setting information desired to be used as a ringtone melody or BGM is selected, the selected music information or setting information can be edited by the information editing module (P2). This editing work includes, for example, changing or adding a tone color parameter and an effect parameter in the setting information, selecting and cutting out a part to be used as a ringtone melody, BGM, or the like from the performance information in the music information, or selecting the selected music. There is "test sounding" in the same setting as when the information is sounded on the terminal system TS side, that is, in the setting state of the timbre and the effect based on the compressed setting information.

  The database DP of the personal computer terminal PC may record information such as the conventional format B of FIG. 6 in addition to the information of the SMF format C and the format A of the own model. It is preferable that similar information editing, setting information attachment in FIG. 9, information compression, and format conversion can be performed.

  On the other hand, when music information is newly created on the personal computer terminal PC, the music information is newly created using, for example, conventional SMF type sequencer software (music information creation software) installed on the computer terminal PC. The module (P3) creates new music information manually input by the user. The new music information created here is, for example, music information according to the SMF format C.

  The new creation module (P3) can also automatically create new music information using automatic music software (apparatus). In this case, the conventional automatic music software or the automatic music device is applied, and for example, only the music (rust part, etc.) of a desired section is obtained from the music information of one music created by the conventional automatic music software. Cut out only information of a minimum necessary track (melody track, chord track, etc.) from the music information composed of a plurality of tracks, so that the music information of the cut out section is connected well when repeatedly played back. It is possible to execute operations such as correcting the connection portion (section start and section end positions). The new creation module (P3) can further directly create music information corresponding to a ringtone melody, BGM, or the like in the format A of the own device.

  Among the information read or edited from the information editing module (P2) and the information newly created by the new creation module (P3), the information whose information format is not the own device format A such as the SMF format C: Information compression and format conversion are performed by the information compression module (P4) and the format conversion module (P5). On the other hand, the information of the format A of the own model is immediately handed to the information transmitting module (P6).

  First, the information compression module (P4) uses the compression table TE prepared in advance to compress the contents of the information other than the format A of the own device so that the information can be stored in the terminal system TS. This compression table TE is prepared for each format combination before and after compression, and describes a predetermined information compression rule. As a specific example of the processing based on this information compression rule, unnecessary information such as the rate scale RS of the SMF format C (see FIG. 7) and excess information in the EG parameter EC described above is converted into the format A of the own device. In addition to the process of reducing the number of times, performance information of necessary tracks (only melody tracks and chord tracks, etc.) is extracted from the performance information of a plurality of tracks (parts), a decorative tone in the performance information is deleted, and performance information is deleted. There is a process of changing the middle pitch bend data to pitch data.

  The compressed information is further converted by the following format conversion module (P5) using the conversion table TC in the same manner as the format conversion module (B4) in the embodiment (first system) of FIGS. Format conversion from SMF format C to own model format A is performed.

  The music information or setting information from the module (P2, P3) which is originally the own model format A and the music information or setting information from the module (P5) compressed and converted into the own model format A are transmitted to the information transmitting module ( By P6), it is transmitted to the terminal system TS side and sent into the terminal system TS via the communication cable 20 and the communication I / F 10.

  On the other hand, in the terminal system TS, music information and setting information from the personal computer terminal PC S are received by the information receiving module (T1) and stored in the main body RAM3. Further, in the setting module (T2), a setting is made by a user's setting operation so that a ringtone melody or BGM sound can be generated based on the received music information.

  The processing of the information receiving module (T1) and the setting module (T2) is the same as the processing of the information receiving module (S2) and the setting module (S3) of FIG.

  In the configuration described above, music information, performance information, and setting information are edited on the personal computer terminal PC. However, the present invention is not limited to this, and an information recording / editing module (U5) shown in FIG. By the same processing as described above, the information received from the personal computer terminal PC (information without editing) can be edited on the terminal system TS side.

  Further, the information recorded in the terminal system TS may be transmitted to the personal computer terminal via the communication cable 20, and the transmitted information may be edited on the personal computer side based on the contents described above. .

[Transfer of information with recording media and other terminals]
FIG. 11 is a functional block diagram showing the information transfer relationship in the terminal system according to one embodiment of the present invention and a third system including a recording medium and other terminals. According to the present invention, the own terminal, that is, the portable telephone terminal system TS can use information received from the external storage medium 19 or other telephone terminals OSa, OSb of the same model or different models for a ring tone, a BGM, and the like. In this case, information compression, format conversion (format conversion), information editing, and the like can be performed in the own terminal system TS.

  In addition, processing of information compression, format conversion (format conversion), information editing, and the like in the terminal system TS, which will be described in detail below, is performed in another telephone terminal (OSa, OSb) to create information of the format A of the own model. After that, the created information can be received by the terminal system TS.

  Music information, performance information, setting information, and the like are recorded in the detachable small external storage medium 19 in the format A of the own model or another format (for example, formats B and C), and the information in which these information are recorded is stored. The medium 19 is mounted on the own terminal system TS, and desired information [information (format type information) indicating which format the information is created in is attached to each information. ] Is read out into the own terminal system TS via the connection circuit 9. In this reading, only desired information can be read by operating a predetermined switch on the operating element 12 of the own terminal system TS.

  Information transmitted from another telephone terminal OSa is taken into the own terminal system TS from the transmission / reception circuit 6 via the telephone line via the base station BS. Information transmitted from another telephone terminal OSb is taken into the own terminal system TS from the communication I / F 10 via the communication cable 20. These telephone terminals OSa and OSb include the same type of telephone terminal using the same format information as the own format A, and the same type A as in the conventional format B or SMF format C, for example. May be a heterogeneous telephone terminal that uses different format information.

  Here, regarding the transmission from the other telephone terminals (OSa, OSb), it is requested to transmit (desired information) to the other telephone terminals (OSa, OSb) by the instruction operation in the own terminal system TS. There is a configuration for notifying, and a configuration for notifying the terminal system TS that it wants to receive (desired information) by an instruction operation on another telephone terminal (OSa, OSb). May be.

  When information is transmitted from other telephone terminals OSa and OSb, information (format type information) indicating in which format the information is created is attached to each information to be transmitted. The setting and use of the received information in real time in the own terminal system TS that is the receiving terminal (that is, the setting and use immediately after reception in the own terminal system TS) is performed by another telephone that is the information transmitting terminal. The terminal OSa and OSb may be configured to be able to make a request. When transmitting information through the base station BS, the base station BS performs information compression, format conversion, and the like (similar to the processes in FIGS. 9 and 10), and then transmits the information to the receiving terminal (own terminal). It can also be configured to do so.

  As described above, the information receiving / reading module (U1) reads out music information, performance information, setting information, and the like from the external storage medium 19, and fetches similar information transmitted from other telephone terminals OSa, OSb. In addition, similarly to the processing described in the operation description of the selective reading module (B1) in FIG. 9, the format type of the read or captured information is determined by the determining module (not shown). As a result of the determination, the information such as the conventional format B or the SMF format C among the read information or the received information includes the setting information attachment module (U2), the information compression module (U3), and the format conversion module. After compression and conversion through the sequence of (U4), the information is handed over to the information recording / editing module (U5), and the information of the own device format A is handed over to the information recording / editing module (U5) as it is.

  The setting information attachment module (U2), the information compression module (U3) and the format conversion module (U4) are basically composed of the embodiment shown in FIGS. 8 and 9 (first system) and the embodiment shown in FIG. 10 (second system). ) Performs the same processing as the setting information attachment, information compression, and format conversion processes by the setting information attachment module (B3), the information compression module (P4), and the format conversion module (B4, P5). This is executed only for information to which no setting information is attached, such as the setting information attached by the setting information attachment module (U2) and the information of the conventional format B. Such information compression and format conversion processing is performed by temporarily receiving all information and writing the information to a memory (main body RAM 3) in the own terminal system TS. There is a method of storing only necessary information in a memory (main body RAM 3). The latter method is effective for a portable telephone terminal having a small memory capacity.

  The information handed over to the information recording / editing module (U5) is recorded in the main body RAM 3 of the own terminal system in the information recording module (U5), and thereafter can be edited using various switches of the operation unit 12. Become like This editing includes adding, deleting, and changing values of various parameters (DA) in the setting information SA.

  Further, in the other processing routine of the sixth step PR6, other information is added to the setting information SA. Specific examples of the other information attached here include an effect program (DSP program) for determining the contents of the effect circuit, audio information, image information, and the like.

  The processing routine of the second to sixth steps PR2 to PR6 is repeatedly executed while the power of the personal computer terminal PC is not detected to be turned off in the next seventh step PR7. This PC terminal process ends.

[Usage examples of audio information and image information]
In the present invention, as described above, audio information and image information are used as setting information other than the tone-related information. For example, audio information includes formats such as WAVE, AIFF, SOUND VQ, and MP3, depending on the difference in compression format, but a common format is applied so that audio information in these formats can be captured, and A voice signal for guidance can be generated concurrently with the generation of the tone signal.

  Further, as an example of using image information, an icon corresponding to an incoming call or a call partner is displayed on the display unit 13 of the terminal system TS, and the movement of the icon is controlled so as to be synchronized with the reproduction of a musical sound. Corresponding musical scores can be displayed sequentially.

[Karaoke function]
In the portable terminal device according to one embodiment of the present invention, when the system is set to the karaoke mode, the so-called "karaoke" in which the music performance and the lyrics display are synchronously processed and the display state of the lyrics is sequentially changed as the music performance progresses. Function can be realized. In order to cause the portable telephone terminal (terminal system) TS to execute the process of the “karaoke” function, the switches included in the operator 12 (FIG. 1) of the terminal system TS are changed to a karaoke mode selection switch, a karaoke song selection switch, and the like. use. In this case, these switches can be provided with switches dedicated to karaoke, or can use switches used for other functions. For example, each time a karaoke mode selection switch is operated, the mode can be switched between a karaoke mode and a non-karaoke mode. When the karaoke mode is set, a karaoke song can be selected by a numeric keypad for inputting a telephone number.

  In the karaoke mode, it is preferable to use music information for karaoke. The music information for karaoke includes performance data and lyrics data in the performance information, and is recorded in advance in a main body ROM (internal memory) together with other music information, or a detachable small recording medium 19, a personal computer It can be received from another external device such as a terminal PC, another telephone terminal, or a base song BS, and can be recorded in the main body RAM (internal memory). In the karaoke mode, based on the karaoke processing function of the main body CPU 1, the music information recorded in this manner is processed, and the setting information and the performance data in the music information are sent to the tone generation control circuit 8 to perform the music performance from the speaker 17 or headphones. While outputting the sound, the display control of the karaoke lyrics is performed on the display unit 13 of the terminal system TS based on the lyrics information in the music information.

[Example of music information format]
FIG. 15 shows a format example of music information usable in the karaoke mode in the portable terminal device. The music information IK applicable to the karaoke mode for one music according to the format A of the own model is composed of setting information SK and performance information MK, and the performance information MK is composed of performance data PK and lyrics data WK. The setting information SK includes timbre information CK including a timbre number and a timbre parameter, and effect information EK including an effect parameter and an effect program, similarly to the setting information SA described above. The setting information SK includes a text flag TF as other information. The text flag TF is information indicating that the lyrics data WK is recorded in the performance information MK. Note that the information recorded as the performance data PK and the lyrics data WK is preferably information in one section (for example, a “rust” portion) of one music piece.

  The performance data PK representing the progress of the music corresponds to the performance information MA described above, and is information in which the timing data PT and the performance events PE are recorded in the performance order, and ends with the end data EP. The performance event PE is information in which a key number and a gate time are grouped. The lyrics data WK is information for displaying lyrics corresponding to performance data (songs) in the performance information IK, and includes timing data WT indicating display timing and text event data indicating lyrics text as display contents. WE are recorded in the order of music progression, and end with end data EW. The timing data WT in the lyrics data WK is synchronized with and corresponds to the timing data PT in the performance data PK so that each text event WE is displayed in synchronization with the performance of the music.

  As described above, the music information accompanied by the lyrics data may be received from the outside similarly to the music information IA, IB, and IC described above. When this music information is received from the outside, not only the performance data (song progress data) but also the lyrics data is processed by the information compression and format conversion processing in the same manner as in each of the embodiments described above. It is converted into the lyrics data WK format. Therefore, the received music information is stored in the form of the music information IK according to the format A of the own model as described above.

  FIG. 16 is a functional block diagram showing a synchronizing process between music performance and lyrics display in the terminal system according to one embodiment of the present invention. Various pieces of music information are recorded in an internal memory (main body ROM2) in advance as shown in an internal memory block KB1, or are stored in a base station BS, another terminal OS, and a personal computer terminal as shown in an external device block KB0. It can be received from an external device such as a PC or a storage medium 19 and recorded in an internal memory (main body RAM 3). In the internal memory, music information is recorded in an information recording format according to the format A of the own model. When music information is received from an external device, when the received music information does not conform to the format A of the own model, as described above, The information is converted into the information recording format of the format A of the own device, and is recorded in the internal memory.

  Desired music information is selected from various music information recorded in the internal memory (KB1). If the selected music information is accompanied by lyrics data WK, the performance data PK and the lyrics data are stored in the information separation block KB2. WK and is handed to the data control circuit block KB3 together with the control command. At this time, the performance event PE is transmitted to the tone generator circuit [24, 36 (FIGS. 2, 3)] of the tone generation control circuit 8 based on the timing data PT of the performance data PK, and is transmitted to the timing data WT of the lyrics data WK. Then, the text event WE is transmitted to the route to the display circuit [5 (FIG. 1)] based on the text event WE.

  The control circuit block KB3 controls transmission of information passed from the information separation block KB2 according to a control command. That is, when the control command instructs the reproduction of the incoming melody song, only the performance event PE is transmitted to the tone generator circuit block KB4, and when the lyrics display (karaoke function) is instructed, the performance event PE and the text are displayed. The event WE (or only the text event WE) is transmitted to the tone generator circuit block KB4 and the display circuit block KB5, respectively. Then, the tone generator circuit block KB4 and the display circuit block KB5 are driven based on the received performance event PE and text event WE, respectively, and perform music performance and lyrics display.

[Reception processing 1]
FIG. 17 is a flowchart of "reception process 1" which is a specific example of the reception process (step TR3 in FIG. 12) in the terminal system according to one embodiment of the present invention. Even if the terminal system TS is operating, it is possible to instruct the start of reproduction of the incoming melody tune in response to a call request from another device.

  The first step KR11 corresponds to a call request confirmation process in a normal mobile phone. In this step, it is determined whether or not there is a call request from another terminal device. Here, if there is a call request, the fact that there is a call request is displayed in step KR12, and then the process proceeds to step KR13. If there is no call request, this reception processing 1 is ended. As a method of displaying the call request in step KR12, specifically, a method of displaying a call request icon on the display unit 13 or a method of blinking a call request icon that is displayed in advance is used when reading lyrics. , So that the ring tone does not suddenly start to sound.

  At step KR13, "1" is set to the RUN flag indicating the reproduction state of the incoming melody tune, and at the next step KR14, the reading of the data currently used is reset to force the current mode to be set before the call starts. And temporarily set the reading of the incoming melody tune. For example, if the current mode is the karaoke mode, the reading of the performance data PK and the lyrics data WK is reset so that the lyrics currently being displayed are erased and the tone being played back is muted before the call starts, and the current tone is reproduced. Stop the mode forcibly. The current mode may be forcibly terminated before the start of a call. On the other hand, for the incoming melody tune, each section is set based on the setting information in the music information selected as the incoming melody sound, and the data readout position is set to the performance data head position.

[Other processing 1]
FIG. 18 is a flowchart of "other processing 1" which is a specific example of other processing (step TR6 in FIG. 12) in the terminal system according to an embodiment of the present invention. To instruct the end of the reproduction of the incoming melody tune. The first step KR21 corresponds to a call start process in a normal mobile phone. In this step, it is determined whether or not a call is to be started. If the call is in the call start state, the process proceeds to step KR22, where the RUN flag indicating the reproduction state of the incoming melody tune is set to "0" to reset it. If the call is not in the call start state, the other processing 1 is terminated.

[Selection / setting process 1]
FIG. 19 is a flowchart of "selection / setting processing 1" which is a specific example of the selection / setting processing (step TR4 in FIG. 12) in the terminal system according to one embodiment of the present invention. The karaoke mode can be activated by operating the karaoke mode selection switch in the operator 12 of the telephone terminal (terminal system) TS. When an instruction to start the karaoke mode is issued by this process, music reproduction and lyrics (text) display are started.

  In the first step KR31, it is determined whether or not the setting of the karaoke mode is performed by operating the karaoke mode selection switch. If the setting operation of the karaoke mode selection switch is performed, the process proceeds to step KR32; / Setting processing 1 ends. In step KR32, the music to be reproduced is selected from the internal ROM. In this case, if there is no lyrics data in the music information of the selected music, that fact is displayed. If no music is selected, the music information currently set as the ring tone is set as the selected music.

  Then, in step KR33, the reading of the currently used data is reset to stop the current mode. In step KR34, the KARAOKE flag indicating that the mode is shifted to the karaoke mode is inverted, and the selection / setting is performed. Processing 1 ends. "1" of the karaoke flag indicates "karaoke mode is being set", and "0" indicates "karaoke mode is being canceled".

  In step KR32, if the KARAOKE flag is "0" and the karaoke mode can be set, there is no lyrics data in the music information of the music selected for karaoke playback (detected by checking the text flag TF). At this time, in step KR34, KARAOKE may be changed from "0" to "1" so that only the music performance is performed in the karaoke mode, or the KARAOKE flag is not inverted so that the mode does not shift to the karaoke mode.

[Interrupt processing]
FIG. 20 is a flowchart of "interrupt processing 2" which is an example of interrupt processing in the terminal system according to one embodiment of the present invention. This process is an interrupt process for the main process in the portable telephone terminal (terminal system) TS of the own model, and is started at each clock timing of the timer. In the first step KR41, it is determined whether or not the RUN flag is "1". If RUN = "1", the process proceeds to step KR42.

  In step KR42, the performance events are sequentially transmitted to the tone generator circuits [24, 36 (FIGS. 2, 3): KB4 (FIG. 16)] based on the performance data, and the corresponding musical tones are generated. That is, RUN = “1” indicates that the incoming melody sound is being reproduced, and the music is reproduced in accordance with the performance data of the music information selected as the incoming melody sound at the time of the call request or the sound of the call request sound. Do. In this case, the progress timing of the music is counted by another interrupt process. Note that while the ring tone is being sounded, the setting of the karaoke mode (KARAOKE = “1”) is ignored, and automatic control is performed so that the display circuit [5 (FIG. 1): KB5 (FIG. 16)] does not progress the lyrics display. Is done.

  On the other hand, if it is determined in step KR41 that RUN = “0”, the process proceeds to step KR43, in which it is determined whether or not the KARAOKE flag is “1”. If KARAOKE = “1”, the process proceeds to step KR44. If not, the interruption process 2 is terminated.

  In step KR44, text events are sequentially transmitted to the display circuit (5: KB5) based on the lyrics data, and the corresponding musical tones are emitted, and the flow advances to step KR42. That is, RUN = "0" (non-playing of ringtone melody sound) and KARAOKE = "1" indicate that the karaoke mode is in effect. In step KR45, the music is reproduced according to the performance data PK of the selected karaoke music. Therefore, when RUN = “0” and KARAOKE = “1”, the process of both steps KR44 and KR42 synchronizes the song reproduction and the lyrics display according to the performance data PK and the lyrics data WK of the selected karaoke song. It can be carried out.

  That is, for the performance data PK, the timing data PT and the performance events PE recorded in the performance order are sequentially read out to reproduce the music, and for the lyrics data WK, the timing data WT and the text event data WE recorded in the display order are obtained. The lyrics are sequentially read and displayed. At this time, since the timing data WT indicating the display timing is synchronized with and corresponds to the timing data PT, the lyrics display can be changed in synchronization with the performance of the music. In the lyrics display, the characters to be uttered or the characters to be uttered in response to the performance of the music among the displayed lyrics are modified such as increasing the brightness, underlining, hatching, and inverting black and white. It is preferable to use such an emphasis display method to simplify the color display of characters in a normal karaoke apparatus.

[Various karaoke modes]
In the karaoke mode, only the lyrics may be displayed without reproducing the music. In that case, it is preferable that the user can arbitrarily operate the progress of the lyrics display.

  Also, lyrics data and performance data corresponding to not only one part of the music but also the whole music may be recorded as performance information. In this case, it is preferable to reproduce only a predetermined portion (for example, a "sabi" portion) of the music at the time of reproducing the ringtone melody, and to reproduce the whole at the time of karaoke reproduction.

  Alternatively, only the lyrics data may be recorded for the entire music. In this case, in the karaoke playback mode ("played" mode), only the lyrics corresponding to the performance data are sequentially displayed, and in the lyrics only mode, the lyrics of the entire music are sequentially displayed according to the user's operation. Should be displayed on the screen.

[Edit function]
In the terminal system according to one embodiment of the present invention, as described in the information recording / editing module (U5) in FIG. 11 and the edit processing (TR5) in FIG. Can edit. Here, a specific example of this edit processing will be introduced.

  An edit mode selection switch and various switches for editing used at the time of the edit processing are included in the operator 12 (FIG. 1) of the terminal system TS. In this case, these switches can be separately provided as dedicated switches, or switches used for other functions can be used. For example, each time the edit mode selection switch is operated, the edit mode and the non-edit mode can be switched. When the edit mode is set, the information to be edited is selected or the parameter value at the time of editing is set by the telephone number input numeric keypad ( The keypad input mode can be switched to "information selection" / "parameter setting" by another key.

[Selection / setting process 2]
FIG. 21 is a flowchart of "selection / setting processing 2" which is another specific example of the selection / setting processing (step TR4 in FIG. 12) in the terminal system according to one embodiment of the present invention. In the first step ER11, it is determined whether or not the setting operation of the edit mode selection switch of the operator 12 of the portable telephone terminal (terminal system) TS is performed. When the operation is performed, the process proceeds to step ER12. When there is no operation, the selection / setting processing 2 is immediately terminated.

  The edit mode selection switch is an operation switch for instructing start and end of the edit mode, and inverts the contents of the EDIT flag each time the switch is operated. Here, when the content of the EDIT flag is "1", it indicates that the camera is in the edit mode, and when it is "0", it indicates that the camera is not in the edit mode (non-edit mode state). Only one mode can be set at a time. For example, if a karaoke mode is set (KARAOKE = "1") when an edit mode setting operation is performed, the karaoke mode is forcibly terminated.

  In step ER12, the EDIT flag is inverted, and the process proceeds to step ER13. In step ER13, it is determined whether or not the EDIT flag is "0". If EDIT = "0" (non-edit mode state), the flow advances to step ER14 to overwrite and save the edited information on the selected information. This selection / setting process 2 ends, and if EDIT = "1" (during the edit mode), the process proceeds to step ER15. By the processing in step ER14, when the edit mode ends, the edited contents stored in the temporary storage area of the main body RAM 3 can be overwritten and saved.

  In step ER15, the input mode of the numeric keypad in the operating element 12 of the terminal system TS is switched to the "information selection" side, and information to be edited is selected from the timbre information, the effect information, the performance data, the lyrics data, and the like using the numeric keypad. By instructing, the instructed information is selected. If no information is selected, the timbre information or the performance data of the music set as the incoming melody is set as the edit information. Then, in the next step ER16, after a part (for example, the head) of the selected (or set) information is displayed on the display unit 13, the selection / setting processing 2 ends.

[Edit processing 1]
FIG. 22 is a flowchart of "edit processing 1" which is a specific example of the edit processing (step TR5 in FIG. 12) in the terminal system according to one embodiment of the present invention. In the first step ER21 of this processing flow, it is determined whether or not the EDIT flag is "1". If EDIT = "1" (during the edit mode), the process proceeds to step KR22 to select data to be edited. On the other hand, if EDIT = "0", the editing process is immediately terminated.

  In step ER22, the display on the display unit 13 is sequentially switched by operating a data selection switch or the like of the operation unit 12, and the values of data to be edited, such as parameters, notes, timings, etc., are displayed. In the next step ER23, an actual editing operation is started, the input mode of the telephone number input numeric keypad of the operation unit 12 is switched from "information selection" to "parameter setting", and a new numeric keypad is operated by operating the numeric keypad. Enter parameter values or add or delete new data.

  Next, in step ER24, the edited contents are temporarily stored in a temporary recording area of the main body RAM3, and the process proceeds to step ER25. Note that the temporarily stored editing contents are overwritten on the actual data at the end of the edit mode. However, overwriting may be performed during the editing mode.

  At step ER25, it is determined whether or not the RUN flag indicating the reproduction state of the incoming melody tune is "1". If RUN = "1" (while the incoming melody tune is being reproduced), at step ER26, the EDIT flag is set to "1". After setting "0", the process proceeds to step ER26, otherwise (RUN = "0": ringing melody tune non-playback state), the edit processing 1 ends. In step ER27, it is determined whether or not the edited content is to be overwritten. If overwritten, the process proceeds to step ER28, where the overwriting is executed, and then the editing process 1 ends. If the overwriting is not performed, the editing process 1 is immediately terminated.

  If there is a call request during the edit mode, the edit mode is forcibly terminated. However, whether or not to keep the edit contents up to the present time can be selected by the user in step ER28. The display of whether or not saving is possible is performed using the display unit 13. In this case, it is only necessary to enable the user to select whether or not to save using the YES / NO operation switch of the operation unit 13. Further, it is preferable that the process is not shifted to the sounding processing of the incoming melody tune while the display of whether or not storage is possible is performed.

  As described in the reception process 1 (FIG. 17: step KR12), when there is a call request in the edit mode (similarly in other modes), an icon indicating that there is a call request is displayed on the screen of the display unit 13. Displayed above. In such a case, the ringtone melody may start to sound, but if the ringtone melody starts suddenly, the user may be surprised. Therefore, it is preferable to display the icon.

  In the edit mode, information such as tone color information, effect information, and lyrics data can be newly created and recorded / registered by using the same procedure as described above, in addition to editing the already recorded information. it can.

[Sound composition function]
In the terminal system according to one embodiment of the present invention, as described as the first example of the automatic music function in the other processing (FIG. 12: TR6), the music information can be created from the voice input to the terminal system. . Here, such a voice composition function will be described. FIG. 23 is a functional block diagram for explaining the voice composition function of the terminal system according to one embodiment of the present invention. The processing for realizing the voice composition function shown by this functional block diagram is basically executed according to an instruction from the main body CPU 1, but the sound control circuit 8 is equipped with a CPU like the sound control CPU 31 in FIG. If so, the processing may be executed in accordance with an instruction from the CPU of the tone generation control circuit.

  The input module CA1 includes a microphone input block CA11 that captures a sound (singing voice) [microphone input sound] input from the microphone 14 (FIG. 1) of the portable telephone terminal (terminal system) TS (FIG. 1), and the transmission / reception circuit 6 A call sound input block CA12 for taking in the call sound (singing voice of the other party) [speech input sound] received via the telephone. The microphone input sound or the call input sound is taken in as a data source.

  The input switching module CA2 for selecting an input sound to be used as a data source operates the telephone number input numeric keypad of the operation unit 12 to determine which of the microphone input sound and the call input sound is to be used as the data source. Set. The A / D conversion module CA3 uses the audio control circuit 7 (FIG. 1) to convert the data source input sound input from the input module CA1 from an analog format to a digital format.

First, the noise amount setting module CA4 sets the volume level of the noise included in the data source input sound from the input module CA1 by the following processing:
(1) For example, a message prompting the user to wait for input is displayed on the display unit 13, and the user is made to wait for a predetermined time to start inputting a microphone sound or a call sound. Detects input sound as noise (detection function).
(2) The maximum volume in the detected noise is set as a noise amount (noise maximum level) (setting function).

  After such processing is completed, the noise amount setting module CA4 displays, for example, a message prompting the start of input on the display unit 13 to urge the user to start inputting a microphone sound or a call sound. The noise elimination module CA5 deletes, from the data source input sound converted into a digital form by the A / D conversion module CA3, sound information having a noise level equal to or less than the maximum noise level set by the noise amount setting module CA5.

  The pitch detection module CA6 extracts a pitch sequence from the data source input sound from which noise has been removed. For extracting the pitch sequence, for example, a detection method based on frequency analysis is used. In addition, in order to reduce the amount of information to be recorded, when it is recognized that a plurality of sounds are generated within a predetermined time, the sound other than the first sound among the plurality of sounds is deleted. Specifically, the minimum length of the note length is set to a predetermined time (for example, eighth note), and sounds generated in a shorter time are deleted. When it is determined that the pitch group does not reach the predetermined range, it is preferable to provide a transpose function for transposing the detected pitch sequence entirely to the predetermined range. With such a transpose function, even if the range of the input sound is a low range, it can be automatically converted to a range usable as a ringtone melody.

  The data creation module CA7 converts the pitch sequence detected by the pitch detection module CA6 into information corresponding to the format A of its own model, and records the information in the main body RAM 3 or the control RAM 35.

[Automatic music function 1]
In the system according to the embodiment of the present invention, as described for the newly created module (FIG. 10: P3) on the personal computer terminal PC side, the automatic music function can be realized. FIG. 24 is a functional block diagram showing the voice composition function according to an embodiment of the present invention in a block form. The processing for realizing the automatic music function shown by this functional block diagram is basically described as being executed by the personal computer terminal PC (FIG. 10: P3). It may be mounted on a computer.

In the manual input module CB1, a user manually inputs (creates) music information by using a conventional sequencer device (a personal computer with a sequencer function) in the following manner:
(1) a method of inputting music information by playing an electronic musical instrument connected to the device,
(2) a method of creating music information by numerical input or the like using a keyboard or mouse connected to the terminal PC, using an input screen displayed on a display device connected to the personal computer terminal PC;
(3) a method of creating music information for one music piece by joining partial music piece data (pattern data) prepared in advance;
And so on.

  On the other hand, in the automatic music module CB2, first, the user inputs partial data of the music to be created. For this input, for example, there are methods of actually playing an electronic musical instrument and using a display screen of a personal computer terminal PC. Note that a plurality of partial music data (pattern data) may be prepared in the personal computer terminal PC in advance, and partial data of the music may be selected from the partial music data. After the partial data of the music is input in this way, the music information for one music is automatically generated from the partial data of the input music by using a known automatic music generation method.

  The music information created by either the manual input module CB1 or the automatic music module CB2 or the music information recorded in the personal computer terminal PC in advance is input to the music analysis module CB3. The music analysis module CB3 analyzes the contents of the music information in order to divide the input (created) music information of one music into musical sections such as an intro, fill-in, main, and ending sections.

  The section division module CB4 divides the music information into a plurality of section information based on the analysis result of the music analysis module CB3, and the section selection module CB5 selects any of the plurality of divided section information as a ringtone melody or BGM. Automatically select whether to use. Regarding the selection of the section information, a plurality of section information may be displayed on the screen, for example, a trial listening may be performed for each section information, and the user may be allowed to select desired section information.

  In the case where the selected section information has a plurality of tracks (parts), the track selection module CB6 narrows down the number of tracks to a necessary minimum. For this narrowing down, for example, if there are a plurality of parts to be played with similar tone colors, there is a method of deleting information on other parts while leaving only one of them.

  In the repetition unit correction module CB7, when the section information for which the processing up to the track selection processing (CB6) has been completed is repeatedly reproduced, the sound at the head position and the sound at the end position in the section are smoothly connected. In this manner, the sound at the section head position or the sound at the section end position (or a sound in the vicinity thereof) is corrected and corrected. Finally, the created section information is recorded in the recording area (RAM) of the personal computer terminal PC by the information recording module CB8, and is output to the information compression module P4 in FIG.

[Automatic generation of music data (automatic music processing)]
In the system according to an embodiment of the present invention, the “other processing” (FIG. 12: step TR6) at the TS terminal and the new creation (FIG. 10: new creation module P3, FIG. 14: step PR3) at the PC terminal. In order to realize the described automatic music function, the music data can be automatically generated on the terminal system TS or the personal computer terminal PC side. FIG. 25 is a processing flowchart schematically showing a method of automatically generating music data in the portable terminal device according to one embodiment of the present invention. In this method, the portable terminal system TS automatically generates music data according to the user's preference such as atmosphere. The music piece data automatic generation processing (automatic music piece processing) shown by this processing flow diagram will be described as being executed by the terminal system TS, but may of course be executed by the personal computer terminal PC. Can be applied to the automatic music module CB2.

  In the method shown in FIG. 25, a plurality of types of melody generation data and chord progression data are provided for each feeling of music in order to automatically generate music data according to the user's preference in the portable terminal system TS. Is stored in the main body ROM 2 or the main body RAM 3 in advance. The melody generation data and the chord progression data may be received from the server station BS via the transmission / reception circuit 6. Alternatively, it may be received from an external device via the communication interface 10 or loaded from the removable small-sized recording medium 19 via the connection circuit 9.

  According to the music data automatic generation processing, a set of melody generation data and chord progression data are selected (for example, randomly) from a plurality of types according to the feeling selected by the user, and based on these data, In addition, the melody is automatically generated while correcting the data according to the user's preference. The automatic generation of such a tune such as a melody is described in detail in a patent application (Japanese Patent Application No. 11-019625) filed by the present applicant, and will be briefly described here.

  The feeling of the music includes, for example, "refreshing", "gently", "sorry", "SEXY". A plurality of types of melody generation data and chord progression data correspond to each feeling, and one of the plurality of types of melody generation data and a plurality of types of chord progression data corresponding to the selected feeling is displayed. , Each is randomly selected. Note that one melody generation data and chord progression data may correspond to each feeling. The melody generation data includes rhythm generation data composed of data such as the number of notes (many, medium, and small), time signature type, presence / absence of syncopated pasage, the number of measures in the music, the composition of the verses, etc. And pitch generation data including data such as a change width of the throat pitch (pitch). Each chord progression data stores data representing chord progression for one song (for example, 32 measures).

  When music is automatically generated, melody generation data and chord progression data are read in the first step CC1 of the processing flow of FIG. For this purpose, for example, in response to a user operation, a plurality of types of feelings of music are displayed on the display unit 13 using words and / or icons (see the column in FIG. 26. An example of a display screen for parameter setting related to composition is shown.) When the user selects a desired feeling using the operating element 12, the selected set of melody generation data and chord progression data are read.

  In the next step CC2, rhythm data is generated based on the melody generation data read in step CC1. That is, based on the rhythm generating data included in the read melody generating data, first, the rhythm data of the motif composed of several measures (for example, the beginning of a song or a chorus portion) (the position of a note is defined). Rhythm data for one piece of music is generated from the generated motif, the above-described phrase configuration data, and the like. For example, as a rhythm generation method for one song, in order to reflect a phrase symbol, a phrase having the same symbol is made to have the same rhythm as the corresponding phrase, and a phrase having a similar symbol is partially (eg, The first half is made the same rhythm.

  The generation of the motif rhythm data is started in response to the operation of a predetermined switch (a dedicated switch or a switch commonly used for other functions) in the operation element 12. The motif is typically generated by storing a large number of rhythm patterns (dot patterns) in advance and selecting a rhythm pattern that matches the rhythm generation data.

  When there are a plurality of candidates for a rhythm pattern suitable for the rhythm generation data, any one of them may be selected at random. Alternatively, the rhythm pattern may be selected in consideration of the above-described feeling or a separately specified music genre. The rhythm data of the motif is not limited to automatically generated rhythm data. The user may directly input the rhythm data manually using the operator 12, or the user may edit the automatically generated rhythm data. Alternatively, as described above, a note sequence may be extracted from a voice input through a microphone or a voice input through a call, and may be employed as rhythm data.

  Next, in step CC3, important hit points are detected from each hit point of the generated rhythm data. Here, the important hit point is a musically important hit point among all the hit points constituting the melody, and as an example, a strong beat for each measure, that is, a hit point on the first and third beats or a hit point on the first and third beats. A hit point near the beat is detected as an important hit point, and other hit points are detected as non-important hit points. The important hitting point may be detected according to other conditions, not limited to the hitting point at or near the strong point.

  On the other hand, in step CC4, based on the melody generation data and the chord progression data, first, a skeleton sound of a motif composed of several measures is generated. A skeleton sound for the music is formed. Here, as the skeleton sound of the motif, a chord component sound having a pitch that falls within the above-described range of pitch and change width is randomly selected. The selection is not limited to the selection at random, but may be selected according to a predetermined rule.

  Next, in step CC5, the skeleton sound generated in step CC4 is assigned to the important hit point detected in step CC3. Subsequently, in step CC6, the pitch is set for the non-important hit point between the important hit points. Assigned. The insignificant hit point is randomly assigned a pitch on the scale of available notes of the corresponding chord sound. The assignment is not limited to random assignment, and assignment may be performed according to a predetermined rule. When forming the pitch of a skeletal sound and an insignificant hit point for one song, the same symbol phrase should have the same pitch as the corresponding phrase, and the similar symbol should be used in order to reflect the phrase symbol as in the case of the rhythm described above. A passage is obtained by making a part (for example, the first half) the same pitch as the corresponding passage.

  The music data generated in this manner is automatically corrected in step CC7 according to a separately stored music rule so as not to cause unnatural sound, and then stored in the main body RAM 3 in step CC8. The music composition process ends.

  Note that the pitch of the automatically generated important sound and / or non-important sound may be modified by the user using the operating element 12. Further, the portion where the pitch can be corrected may be only the motif portion or the entire music. Further, in the above description, after generating the rhythm data of the entire music, the pitch of the entire music is given. However, first, the rhythm data of the motif is generated, and then the pitch of the motif is given. Alternatively, the rhythm data of the subsequent portion of the music may be generated, and the pitch of the subsequent portion may be assigned.

  In the above-described method of automatically generating music data, only a melody is generated. In addition, an accompaniment part may be automatically generated. For example, a plurality of accompaniment generation data (also referred to as “style data”) for each music style (style) is composed of performance data for one to a plurality of bars created according to a predetermined chord type for one or a plurality of parts. Is stored in the main body ROM 2 or the main body RAM 3 in advance, the accompaniment generation data corresponding to the music style selected by the user or the music style selected at random is read out using the operating element 12, and based on the chord progression data. Then, the pitch data included in the accompaniment generation data is corrected so as to match the chord progression data, and this is repeated for one music (for example, 32 measures) to generate an accompaniment part. Note that the style of the music includes "urban", "earthy", "tropical", "danceable", and the like (see the right column in FIG. 26).

[Chord detection processing and accompaniment part assignment processing]
In one embodiment of the present invention, as described as one of the automatic music composition functions (FIG. 12: step TR6 "Other processing"), the terminal system TS plays the performance information that is compatible with the performance information already created or stored. Can be automatically generated. FIG. 26 is a flowchart schematically illustrating a "method of automatically determining a chord (chord progression) adapted to music data" (chord detection processing) in the portable terminal device according to an embodiment of the present invention. FIG. 27 is a flowchart schematically illustrating a “method of assigning an accompaniment part familiar with melody data to melody data” (accompaniment part assignment processing) in the portable terminal device according to an embodiment of the present invention. The chord (chord progression) determined by the chord detection processing of FIG. 26 can be used for automatic accompaniment in the accompaniment part assignment processing of FIG.

  In the chord detection processing of FIG. 26, first, in step CD1, the melody data is divided into sections according to a predetermined rule. Here, one section to be divided is a section that can be regarded as continuing one chord. Examples of the predetermined rule include a rule that divides the data into fixed intervals such as one beat, two beats, and one bar, an analysis of the arrangement of melody data, and detection of a range that can be regarded as one chord interval. There are rules for dividing by position. In this case, a plurality of rules may be applied simultaneously.

  Subsequently, in step CD2, a harmony is detected for each section of the divided melody. The detection of the harmony is performed by analyzing the arrangement of the melody data and detecting a sound that can be regarded as a harmony in each section. Further, the process proceeds to step CD3, where the melody is analyzed to detect a key. For example, the degree of appearance of each note name forming the melody (the number of simple note names or a value obtained by adding the pitch for each note name) may be matched with the scale note of each key. Then, the key with the highest matching degree is detected as the melody key.

  Next, in step CD4, a chord or a chord progression is matched for each of a plurality of continuous sections of the melody or for each single section based on the detected chord and the detected key. Specifically, typical chord progressions for a plurality of continuous sections (for example, four sections, three sections, two sections, etc.) are stored in a database for each key, and a plurality of continuous sections are detected. The chords are compared with the constituent tones of each chord progression in the detected key. First, the chord progression in the four sections is compared with the chord progression in the four sections, and if there is a match, the decision is made. If there is no match, the number of sections is reduced and the chord progression in the three sections and the sum of the three sections are determined. Compare it with the voice to determine what matches. If there is no match in three sections, matching is performed in two sections. If there is still no match, a single chord component sound is compared with a single section chord sound to determine the best matching chord. .

  In step CD5, the chord progression or chord having the highest matching degree is determined as the chord of the section by such matching processing, and the chord detection processing ends. It should be noted that the chord progression is not limited to the one having a chord progression for each key, but the chord progression is performed only for a specific key. May have a chord progression.

  In the accompaniment part assigning process of FIG. 27, the accompaniment part includes a chord progression that is adapted to the melody data and style data stored in advance. , C major), a large number of performance data for one or more measures are stored in the database. ]. As described above, the chord progression adapted to the melody data can be obtained by a method of detecting from the melody, a method of storing it in the melody data in advance, a method of designating the melody by a user, and the like. The melody data including the chord progression may be downloaded from a base station (server station) BS.

  In this accompaniment part assigning process, first, in step CE1, the user selects any one of a large number of stored accompaniment style data. Each accompaniment style data is provided with a term representing the content of the accompaniment style data (for example, a music genre such as pop or classical music, or a term indicating an atmosphere such as "bright" or "dark"). The term list is displayed on the display unit 13 of the portable terminal device TS, and any one of the accompaniment style data is selected by using the operation unit 12 to select one. Alternatively, a number assigned to each accompaniment style data may be selected using a numeric switch included in the operation element 12.

  Next, in step CE2, the selected accompaniment style data is read from the database, and in step CE3, the chord progression is obtained. Further, in step CE4, the pitch of the performance data included in the read accompaniment style data is determined. The music data is modified according to the acquired chord progression, and performance data of the accompaniment part is generated. The correction of the performance data pitch is performed by a pitch conversion table prepared for each chord type (a table that defines how much the pitch of the performance data is corrected according to the chord type. When the pitch of the performance data is shifted by the correction amount, a pitch matched to the designated chord type is obtained.

  Then, in step CE5, the performance data of the accompaniment part generated in step CE4 is added to the melody data to create a melody composed of a plurality of parts, and the accompaniment part assigning process ends.

  The accompaniment style data may be composed of a plurality of sections, and the progress of the sections may be specified. For example, sections of accompaniment style data include an intro section, a main section, a fill-in section, an ending section, and the like. The user can specify the arrangement of each section and the number of repetitive playbacks of the main section according to the progress of the melody data. The section progress data in which the sequence and the number of times of repetitive reproduction of the main section are programmed may be stored and read out in accordance with the progress of the melody data to designate the section progress. In this way, it is possible to obtain a variety of accompaniment part performances.

(Various embodiments)

For example, a tone control circuit as shown in FIG. 3 is mounted, and by operating an automatic performance function (sequencer) used in a conventional electronic musical instrument in this circuit, music information in SMF format C is reproduced as it is. It is also possible to do it. In this case, it is not necessary to perform format conversion when information is taken into the portable telephone terminal from another tone information source device (such as a PC). However, it is preferable to perform compression processing.

  In the embodiment, the FM system is adopted as the tone synthesis system in the tone generator circuit, but the tone synthesis system is not limited to this. For example, various systems such as a waveform memory system, a physical model system, a harmonic synthesis system, a formant synthesis system, and an analog synthesizer system of “VCO + VCF + VGA” can be applied, and any of these systems may be used. In other words, various types of information relating to the timbre recorded as setting information differ depending on the tone synthesis method of the tone generator circuit. However, basically, various parameters corresponding to each tone synthesis method conventionally used in electronic musical instruments have been used. Information can be adopted.

  Further, the tone generator circuit itself is not limited to a tone generator circuit configured using dedicated hardware, but may be configured using a “DSP + microprogram” or a “CPU + software”. The sound source circuit may be configured by a program.

  Further, a plurality of tone generation channels may be formed by using one circuit in a time-division manner, or a type in which one tone generation channel is constituted by one circuit may be used.
