[Effects of the Invention]
According to the present invention (all claims), in music creation (editing) on a portable terminal, a plurality of performance patterns are prepared in order to edit music, and a switch operator such as a numeric keypad (6s: SW1-SW6). 6a: A performance pattern is assigned to each of SW7 to SW12) to function as a “pattern assignment / instruction switch” (4, E2, E3). Then, the timing at which the performance pattern should be reproduced is specified by a musical delimiter position (ts1, ts2,...; Beat or bar line) on the time axis or a temporal position (ta1, ta2,...) Finer than the delimiter position. Then, by operating the operation elements (6s, 6a) to select a performance pattern, the data (pattern number) indicating the selected performance pattern is changed to the designated musical delimiter position and detailed time A pattern sequence (FIG. 7) arranged in the reproduction order according to the position is created (E8, E9). Therefore, a variety of music can be created by a simple operation on the mobile terminal. In addition, the selection of a performance pattern uses a switch operator such as a numeric keypad provided in a portable terminal and follows the conventional operability, so that the user can easily become familiar with the editing operation.
In particular, in the music editing according to the first feature of the present invention (claims 1 and 9), a performance pattern composed of "MIDI-like" data representing a pronunciation instruction is prepared, and musical break positions (ts1, ts1, 9) are prepared. When the operator (6s, 6a) is operated by designating ts2,..., or a fine temporal position (ta1, ta2,...), the performance pattern assigned to the operator is designated as the specified musical break position. A pattern sequence (FIG. 7) for instructing playback at a timing corresponding to a fine temporal position is created. Therefore, a variety of musical pieces in which a performance pattern in the “MIDI-like” format is sequentially played back at a musical delimiter position or a fine temporal position timing can be created by a simple operation on the portable terminal.
In the music editing according to the second feature of the present invention (claims 2 and 10), the performance pattern of the first format composed of "MIDI-like" data representing the pronunciation instruction and "WAVE" representing the sound waveform. A plurality of performance patterns of the second format composed of format data are prepared, and the performance patterns of the first format (“MIDI-like” format) are musically separated (ts1, ts2,...) The temporal position (ta1, ta2,...) Is designated and the corresponding operation element (6s, 6a) is operated, and the performance pattern in the second format (“WAVE” format) has a fine temporal position (ta1, ta2,. ...) and operating the corresponding operator (6a), if the performance pattern assigned to the operator is in the first format ("MIDI-like" format), the specified musical break position or In the case of the second format (“WAVE” format), each is instructed to be played back at a timing corresponding to a specified fine temporal position so that the playback is performed at a timing corresponding to a long temporal position. A pattern sequence (FIG. 7) is created. Therefore, with a simple operation, a portable MIDI terminal has a musical interval position and a fine temporal position timing for a “MIDI-like” performance pattern, and a fine temporal position timing for a “WAVE” performance pattern. With this, you can create a variety of music that will be played sequentially.
[0011]
Furthermore, in the music editing according to the third feature of the present invention (claims 3 and 11), a first type performance pattern called a “synchronization pattern” that is reproduced in synchronization with a musical break position and an arbitrary timing. A plurality of second-type performance patterns called “asynchronous patterns” to be reproduced are prepared, and musical delimiter positions (ts1, ts2,...) Are designated for the first-type performance patterns (synchronous patterns). If the corresponding operator (6s) is operated, and the second type performance pattern (asynchronous pattern) is operated by operating the corresponding operator (6a) by designating a fine temporal position (ta1, ta2,...) If the performance pattern assigned to the child is the first type (synchronous pattern), the performance pattern is played back in synchronization with the timing corresponding to the specified musical break position. As shown, in the case of the second type (asynchronous pattern), an instructing pattern sequence (FIG. 7) is created so as to be reproduced at a timing corresponding to a specified fine temporal position. . Therefore, in the portable terminal, the first type performance pattern (synchronous pattern) is synchronized with the timing of the musical break position by a simple operation, and the second type performance pattern (asynchronous pattern) is finely positioned in time. It is possible to create a variety of music that is played back sequentially at the timing of
That is, when creating a pattern sequence (FIG. 7), if the performance pattern assigned to the operated operator (6s) is of the first type (synchronous pattern), it is designated among the events that constitute the performance pattern. The instruction data for starting playback from an event corresponding to the timing of the musical break position (ts1, ts2,...) Is recorded, and the operator (6a) to which the second type performance pattern (asynchronous pattern) is assigned. For the performance pattern selected by the operation, if the performance pattern assigned to the operated operation element (6a) is of the second type (asynchronous pattern), an arbitrary timing (ta1) corresponding to a fine temporal position. , Ta2,...), Instruction data for starting reading from the head of the performance pattern is recorded. , For the first type (synchronization pattern) reproduced from the timing of the musical delimiter position is started, the reproduction is started from any timing for the second type of performance patterns (asynchronous pattern). Therefore, various musical pieces can be easily created by changing the arrangement order of performance patterns or changing the types of performance patterns.
[0012]
In the present invention, the storage means (3, 5) of the portable terminal further stores a plurality of performance patterns in a pack which is a minimum storage unit that can be individually recognized by the OS (Operating System) of the portable terminal ( The performance pattern assigned to each operator can be determined by selecting a pack by the “pattern pack” and pack selecting means (6c, 6e, E1). Therefore, by selecting a desired performance pattern from the selected desired pack by operating the operator, a desired pattern sequence (FIG. 7) in which pattern designation data (pattern number) for designating the performance pattern is arranged is created. be able to. If a pack changing means (E4) is further provided to change the pack (number) of the already created pattern sequence (FIG. 7), the contents of the pattern sequence can be changed without changing the pattern instruction data (pattern number). It can be configured to change to another song, and this configuration allows you to edit an existing performance pattern array to a new song just by changing the type of pack, creating a variety of songs It is possible to contribute and further promote the desire to create music.
[0013]
In the present invention, on the screen called “pattern sequence creation (edit) screen” of the display (11) of the portable terminal, the musical delimiter positions (ts1, ts2,...) On the time axis and the delimiter positions are finer. The time position (ta1, ta2,...) Is displayed (11, E5), and the musical break position and the fine time position are indicated, thereby easily specifying the timing at which the performance pattern should be reproduced. be able to. (Claim 5)
[0014]
In the present invention, the pattern instruction data (pattern number) for instructing the performance pattern selected by the operation of the switch operator (6s, 6a) corresponds to the predetermined timing (ts1, ts2,..., Ta1, ta2,...). When the pattern sequence arranged in the reproduction order (FIG. 7) is created (E8, E9), the pattern sequence is stored in the storage means (3, 5) of the portable terminal according to the instruction of the pattern instruction data (pattern number). The data format is changed to music data (FIG. 8) in which the recorded performance patterns are sequentially developed (E11). This music data is event format data that can be reproduced in common by a plurality of types of information devices including mobile terminals such as mobile phones, and is used as it is in other devices that do not store various performance patterns. be able to. (Claim 6)
[0015]
In addition, the obtained music data can be transferred to other information devices such as mobile phones by setting the transfer permission / inhibition information (transfer flag or transfer bit) to be transferable. In other words, the original data before editing, such as performance patterns, is usually set so that it cannot be transferred, but the music data obtained by editing can be effectively used in other information devices by changing it to transferable. Can be used. (Claim 8)
Further, the obtained music data is set such that the editability information (edit flag or transfer bit) is set to be uneditable and the music data cannot be edited. In other words, the original data before editing such as the performance pattern is usually set to editable, but the music data obtained by editing is changed to non-editable so that the user's individual result data becomes effective. Can be protected. (Claim 9)

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. The following embodiments are merely examples, and various modifications can be made without departing from the spirit of the present invention.
[0018]
[System Overview]
FIG. 1 is a block diagram showing a schematic hardware configuration of a portable terminal according to an embodiment of the present invention. In this example, the mobile terminal is a mobile communication terminal such as a mobile phone, a central processing unit (CPU) 1 that controls each part of the terminal and performs various data processing, and a timer that generates a clock for these control and processing 2, a read-only memory (ROM) 3 in which programs such as OS and applications and various control data are recorded, a random access memory (RAM) 4 in which control and processing data are temporarily stored, a recording medium such as a semiconductor memory And storage means such as an external storage device 5 that functions as a memory for storing various data.
[0019]
Various data and application programs related to the music reproduction and creation application according to the present invention can be recorded in a memory such as the ROM 3 or the external storage device 5. For example, performance pattern data (also simply referred to as “pattern”), pattern sequence data, music data, and the like used in a music reproduction and creation application are recorded, and the performance pattern and pattern sequence data are stored in a storage unit called “pattern pack”. To be recorded.
[0020]
As an input means, an operator circuit (operation unit) 6 for inputting necessary information to the terminal system based on various input operations by an operator such as a pattern assignment / instruction switch (6s, 6a), a user's voice, and the like are input. A microphone circuit 7 and the like. The radio wave transmitter / receiver 8 controlled by the CPU 1 transmits / receives a call sound signal and a data signal to / from other communication terminals and servers via the antenna 9. A sound signal such as a received call sound signal is heard by the user through the sound speaker circuit (receiver) 10 under the control of the CPU 1.
[0021]
The display circuit (display unit) 11 controlled by the CPU 1 includes a display (11d) such as an LCD, and displays visual information necessary for various operations / controls / processing of the portable terminal including transmission and reception. The portable terminal is further provided with a sound signal generation circuit 12 including a tone generation sound source and a sound system 13 including a tone speaker (sounder) in order to emit music such as an incoming melody. Further, a communication interface (I / F) 14 is provided, and various data and programs can be transmitted and received between the CPU 1 and other information devices such as a personal computer (PC).
[0022]
This portable terminal can be connected to an external device such as a server on the Internet or another information processing apparatus using the radio wave transmitter / receiver 8 or the communication I / F 14, and can acquire a pattern pack from the external device, Music data created by this portable terminal can be distributed to an external device.
[0023]
[Basic operation of system and pattern pack]
In a portable terminal such as a cellular phone to which the present invention is applied, the relationship between the OS (system program) installed in the portable terminal and the application program is that the OS is always activated while the terminal power is on. A plurality of application programs are executed on the OS. Therefore, the music reproduction process and the music creation (editing) process according to the present invention correspond to one of such application programs.
[0024]
Regarding the handling of data in such a portable terminal, the memory is divided into a plurality of areas, and only one data can be recorded in one area. Further, the number of data that can be managed by the OS is determined, and the number of memory areas is the maximum number of data that can be managed by the OS.
[0025]
In one embodiment according to the present invention, in response to such basic operating conditions in a portable terminal, the device is designed to handle performance patterns used in music playback and creation applications, and a plurality of pattern data (for example, 12 patterns) are put in one “pattern pack” (also simply called “pack”), and each “pattern pack” is recorded in each memory area, so that a plurality of patterns contained in each “pattern pack” are recorded. The OS recognizes the entire data as one data, and performs pattern data management such as extracting a plurality of pattern data from one “pattern pack” by an application program [music reproduction processing and music creation (editing) processing]. Thus, the memory can be used efficiently.
[0026]
That is, since only one data that can be recognized by the OS can be recorded in one memory area, when only one data is recorded, the remaining unused area becomes an unusable area. When one pattern is recorded in one memory area as one pack (one data), the remaining capacity of the memory area is clearly less than when only one pattern is recorded as one data in one memory area. Memory usage efficiency can be greatly improved.
[0027]
FIG. 2 shows an example of the structure of a pattern pack used in a music reproduction and creation application according to an embodiment of the present invention. In the music reproduction and creation application, a plurality of pattern packs are used, and one pattern pack is recorded in one memory area in the ROM 3 or the external storage device 5. As shown on the left side of FIG. 2, each pattern pack is composed of a pack number, performance pattern data (performance pattern, pattern) and pack end data, and the OS uses information from the pack number to the pack end as one data. recognize.
[0028]
In addition, as shown on the right side of FIG. 2, a single pack contains a plurality of performance pattern data. The performance pattern data is data for reproducing a musical piece of about one measure, and is used as segment data for assembling the musical piece. Each performance pattern data includes a pattern number, an edit flag, a transfer flag, event sequence data, and pattern end data. On the other hand, the tone reproduction and creation (editing) processing application recognizes each pattern information from the pattern number to the pattern end data as one pattern. One pattern pack contains, for example, twelve pattern data of “pattern 1” to “pattern 12”. In the following, description will be made according to examples of these twelve patterns.
[0029]
Here, a plurality of patterns included in one pattern pack are created with musical relevance. For example, a plurality of patterns included in one pattern pack are created along the same musical genre (rock, jazz, pops, etc.), the same singer, the same composer, and the like. In addition, a plurality of patterns included in one pack are divided into a synchronous pattern group and an asynchronous pattern group. In the following example, among 12 “pattern 1” to “pattern 12”, “pattern 1” to “pattern 1” “Pattern 6” is a synchronous pattern, and “Pattern 7” to “Pattern 12” are asynchronous patterns.
[0030]
The synchronization pattern is pattern data whose reproduction is started in synchronization with musical break positions such as beats or bar lines. Similar to the so-called MIDI format, the event sequence data of the synchronization pattern is data in which events representing the sound generation instruction command for the tone generation sound source of the tone signal generation circuit 12 are recorded in the order of performance progress, and is in the “MIDI-like” format. Called.
[0031]
In addition, the asynchronous pattern is pattern data whose reproduction is started immediately at the timing when the reproduction instruction is given. As the event sequence of the asynchronous pattern, not only data in the “MIDI similar” format as in the synchronous pattern but also data in the “WAVE” format can be used. “WAVE” format data refers to data in which events representing discrete values at each sampling timing of musical sound waveforms are recorded in the order of performance, and are not limited to pure musical musical tone information such as musical instruments, but also voice and natural sounds (effects) Sound) that can be used musically.
[0032]
[Configuration of allocation buffer and operation / display section]
FIG. 3 shows a configuration example of an allocation state buffer used in the music reproduction and creation application according to one embodiment of the present invention. In the music reproduction and creation application, as shown in FIG. 3, the pack number of the currently selected pattern pack and the pattern assignment / instruction switches SW1 to SW12 of the operation unit 6 are stored in the assignment state buffer provided in the RAM 4. The pattern number assigned for each is stored. In the example shown in the figure, the pattern pack having the pack number (PACK) “3” is currently selected, and pattern numbers “1”, “2”, “3”, SW12 are assigned to the switches SW1, SW2, SW3,. .., "12" is assigned, and pattern data corresponding to the pattern number of the switch can be selected by operating the switches SW1 to SW12.
[0033]
FIG. 4 shows a switch configuration example of a portable terminal according to an embodiment of the present invention. As shown in FIG. 4, a display 11d and various switches / keys 6m, 6c, 6e, 6s, 6a are provided on the operation surface of a portable terminal such as a cellular phone, and an antenna pole is provided at the upper end of the case. 9p is provided. The mode switch 6m has a function of sequentially switching the operation mode of the mobile terminal every time it is operated. For example, when the music playback mode is entered by operating the mode switch 6m, the display 11d is recorded on the mobile terminal. All pattern packs are displayed with the pack name and pack number.
[0034]
In this case, the “ENTER” key 6e functions as a pack determination switch, and the cursor is moved to a desired pattern pack display on the display 11d by operating the cursor key 6c such as “▲”, “▼”, and the “ENTER” key. By operating 6e, a pattern pack to be used can be selected and determined. In the music playback mode or music creation (editing) mode, the numeric keypad, the “*” key, and the “#” key function as the above-described pattern assignment / instruction switches SW1 to SW12. Of course, the numeric keypad functions as a switch for inputting a numerical value such as a telephone number in a normal mode for making a call.
[0035]
“1” to “6” keys in the numeric keypad are the above-described switches SW1 to SW6, and one synchronization pattern corresponding to the pattern numbers “1” to “6” in the pattern pack is assigned one by one. Belongs to the synchronization pattern assignment / instruction key 6s.
[0036]
The “7” to “0” key, “*” key, and “#” key in the numeric keypad are the above-described switches SW7 to SW12 (“*” → SW10, “0” → SW11, “#” → SW12). Asynchronous patterns corresponding to the pattern numbers “7” to “12” are assigned one by one and belong to the asynchronous pattern assignment / instruction key 6a for instructing each asynchronous pattern.

[Outline of music playback]
FIG. 5 is a diagram showing an example of pattern playback operation in a music playback application according to an embodiment of the present invention. In this figure, the time axis is taken on the horizontal axis, and the long vertical lines represent bar line timings ta, tb, tc, td,... Corresponding to bar lines. The short vertical line represents the beat timing. For example, the beat timing tb3 is the third beat timing of the measure section between the measure timings tb to tc.
[0038]
The outline of the music reproduction will be described with reference to FIG. 5. A performance pattern is assigned to each of the switch operators 6s, 6a such as a numeric keypad provided in a portable terminal such as a cellular phone, and the switches SW1, SW7, SW2 are sequentially arranged. ,... Are operated (t1, t2, t3,...), The performance patterns “1”, “7”, “2”,. A plurality of performance patterns to be played are included for each pack, which is the minimum unit of information that can be individually handled by the OS installed in the mobile terminal, and can be used as a switch according to the selection of the pack by the music playback or creation application. A performance pattern to be assigned is determined. The performance patterns stored in each pack include a synchronous pattern and an asynchronous pattern. The synchronous patterns “1”, “2”,... Are musical timings ta, tb3,. The reproduction is started immediately, and the asynchronous pattern “7”,... Is immediately started at the switch operation timing t2,.
[0039]
Hereinafter, according to FIG. 5, an operation example of pattern reproduction when the music switch mode is entered by operating the mode switch 6m and the cursor key 6c is operated to select a certain pack and then the pattern assignment / instruction switches SW1 to SW12 are operated. Each of the following events (1) to (7) will be described in order. In this operation example, for convenience, all patterns used in the music reproduction process are described as one bar length, the synchronization pattern is MIDI-like data, and the asynchronous pattern is WAVE data. Further, “pattern 1”, “pattern 2”, and “pattern 7” of the selected pattern pack (for example, the third pack) are assigned to the switches SW1, SW2, and SW7, respectively. “Pattern 2” is a synchronous pattern, and “Pattern 7” is an asynchronous pattern.
[0040]
(1) First, when the first switch SW1 ("1" key) of the synchronization pattern assignment / instruction key 6s is pressed at a certain timing t1, "pattern 1" of the pattern pack starts to be read from the head event. Start playing pattern data. In this case, since the operation of the switch SW1 is the first switch operation of the pattern instruction, the timer 2 which measures the reproduction time uses the timing t1 as the first bar line timing ta (= 0) and measures the reproduction time. Start. That is, the timer 2 is reset at this timing t1.
[0041]
(2) When the first switch SW7 ("7" key) of the asynchronous pattern assignment / instruction key 6a is pressed at the timing t2, the timing t2 when the switch SW7 is pressed is neither a beat timing nor a bar line timing. Since “pattern 7” instructed by the switch SW7 is an asynchronous pattern, reading of the “pattern 7” of the pattern pack is immediately started from the head event at the operation timing t2 of the switch SW7.
[0042]
(3) When the second switch SW2 ("2" key) of the synchronization pattern assignment / instruction key 6s is pressed at timing t3, the timing at which the switch SW2 is pressed is neither beat timing nor bar line timing, but "pattern 2 Since “” is a synchronous pattern, the reproduction start of “pattern 2” is waited until the first beat timing tb3 after the timing t3 when the switch SW2 is operated. When the beat timing tb3 immediately after the operation arrives, the reading of “pattern 2” is started from the event corresponding to the beat timing tb3 (the third beat event). Therefore, after the start of reading, a plurality of synchronization patterns “pattern 1” and “pattern 2” are reproduced in parallel.
[0043]
(4) At the playback end timing t4 for one asynchronous pattern, the playback of the asynchronous pattern being played back is automatically stopped. That is, “pattern 7”, which is an asynchronous pattern, starts playing at timing t2 and ends playing once at timing t4, so that playback stops at timing t4.
[0044]
(5) When the synchronization pattern assignment / instruction switch SW1 is pressed at timing t5, “Pattern 1” corresponding to the switch SW1 is being reproduced, and an operation on the synchronization pattern being reproduced is interpreted as reproduction stop of the pattern. Therefore, it is determined that the reproduction stop of “Pattern 1” has been instructed. However, since the timing t5 at which the switch SW1 is pressed is neither a beat timing nor a bar line timing, the reproduction of “pattern 1” is stopped when the next beat or bar line timing tc arrives.
[0045]
(6) When the asynchronous pattern assignment / instruction switch SW7 is pressed again at the timing t6, since the “pattern 7” instructed by the switch SW7 is an asynchronous pattern, immediately at the timing t6 when the switch SW7 is operated, Reading starts from the first event of “pattern 7”.
[0046]
(7) When the asynchronous pattern assignment / instruction switch SW7 is pressed at the timing t7, the operation of the switch SW7 at this timing is ignored because the timing “t7” is a period during which the “pattern 7” of the asynchronous pattern is being reproduced. .
[0047]
[Outline of song creation (editing)]
FIG. 6 shows a display example of a pattern sequence creation (editing) screen in the music creation application according to one embodiment of the present invention. When the music creation (editing) mode is entered by operating the mode switch 6m, all the pattern packs that can be used for creating the pattern sequence are displayed on the display 11d by the pack name, the pack number, etc., as in the music playback mode. . Therefore, the user operates the cursor key 6c to select a pack number to be used for creating a pattern sequence, and operates the “ENTER” key 6e to determine a pattern pack to be used for creating a pattern. As a result, a pattern sequence creation (edit) screen as shown in FIG. 6 appears on the display 11d.
[0048]
The outline of music creation (editing) will be described with reference to FIG. 6. A performance pattern is assigned to each of switches 6s and 6a such as a numeric keypad provided in a portable terminal such as a cellular phone. In the synchronous pattern display field TS1, TS2 or the asynchronous pattern display field TA on the pattern sequence creation (edit) screen, the pattern writing section WA is designated according to the scale representing the timings ts1, ts2,... Or the timings ta1, ta2,. When the switch is selectively operated, the performance pattern assigned to the switch is associated with the section WA, and a pattern sequence is generated that gives an instruction to reproduce the selected performance pattern at the timing of the section WA. When the performance pattern is a synchronous pattern, the pattern sequence instructs to start reproduction from an event corresponding to the designated timing ts1, ts2,..., And when the performance pattern is an asynchronous pattern, the designated timing ta1, ta2,. Instructs to start reading from the top.
[0049]
More specifically, in the pattern sequence creation (edit) screen, the passage of time is taken in the horizontal axis direction, a plurality of pattern display fields TS1, TS2, TA are arranged in the vertical axis direction, and these pattern display fields TS1, In TS2 and TA, a pattern sequence of a synchronous pattern and an asynchronous pattern can be expanded and displayed. In the screen example of FIG. 6, two synchronous pattern display columns TS1 and TS2 are arranged in the upper two rows, and an asynchronous pattern display column TA is arranged in the lower one row. The first and second synchronization pattern display fields TS1 and TS2 can respectively display the pattern sequences recorded on the first track and the second track of the synchronization pattern, and the asynchronous pattern display field TA displays the asynchronous pattern. The pattern sequence recorded on the track can be displayed. The number of tracks (= number of pattern display fields) can be increased or decreased as appropriate according to the processing capability of the mobile terminal.
[0050]
In this screen example, a bar line LB is displayed across each column TS1, TS2, TA so that the temporal position can be easily grasped. Between the upper and lower stages, temporal scales representing musical timings such as beat timings ts1, ts2,... Are displayed along the time axis corresponding to the synchronization pattern display fields TS1, TS2, and beat timings. are displayed in correspondence with the asynchronous pattern display column TA. ts1, ts2,..., more detailed musical timings ta1, ta2,.
[0051]
In creating the pattern sequence, first, the cursor key 6c is operated to instruct each pattern display field TS1, TS2, TA, the start point of the pattern is designated in each field, and the “ENTER” key 6e is pressed. The starting point of the pattern is determined by the operation. For the asynchronous pattern, it is only necessary to set the start point by this method, but for the synchronous pattern, the end point of the pattern is further designated by the cursor key 6c and determined by the “ENTER” key 6e.
[0052]
Thus, when the pattern arrangement range is set by determining the start point and the end point, the set range is shaded, and this shaded portion WA represents a new pattern writing portion set by the user. Further, when a switch corresponding to a pattern to be attached to this portion is selectively operated from among the pattern assignment / instruction switches 6s and 6a (SW1 to SW12), a desired pattern is developed and displayed on the shaded portion WA. . Then, by operating the enter (“ENTER”) key 6e, this pattern is recorded at the corresponding position of the corresponding track.
[0053]
In FIG. 6, in the illustrated time range, the pattern sequence of the first track of the synchronization pattern and the track of the asynchronous pattern in the pattern display fields TS1 and TA has already been created, and the second track of the synchronization pattern is the second synchronization. “Pattern 2” is written in a predetermined section of the pattern display field TS2, and after that, a pattern writing section WA for writing a new pattern is set by shading after one beat. Has been.
[0054]
For the synchronization pattern, the start and end points of the pattern writing section WA can be specified by beats or bar line timings ts1, ts2,..., As shown in “Pattern 2” in the synchronization pattern display field TS2. It is pasted so as to coincide with the bar line LB and beat position of the set section. As for the asynchronous pattern, for example, as shown by the scale at the top of the asynchronous pattern display field TA, the start time of the pattern writing section WA is specified at timings ta1, ta2,... Finer than the beat timings ts1, ts2,. be able to.
[0055]
FIG. 7 shows an example of the configuration of pattern sequence data created by a music creation application according to an embodiment of the present invention. The pattern sequence data (also simply referred to as “pattern sequence”) using the creation (edit) screen as shown in FIG. 6 is the pack number of the pack being used, the first track of the synchronization pattern, as shown on the left side of FIG. Data, synchronous pattern second track data, asynchronous pattern track data, and pattern sequence end data.
[0056]
The synchronous pattern first track data, the synchronous pattern second track data, and the asynchronous pattern track data correspond to the display data in the pattern display fields TS1, TS2, TA on the creation (edit) screen of FIG. These track data include a track identifier, instruction sequence data (also simply referred to as “instruction sequence”), and track end data, as shown in the upper center of FIG.
[0057]
As shown in the lower part of FIG. 7, in the case of the sync pattern track, the instruction sequence data includes the beat timing data indicating the start time and start beat of the reproduced sync pattern, and the start time to the end time of the played sync pattern. A set of reproduction length data representing time and reproduction pattern instruction data (pattern number) for instructing a synchronization pattern reproduced from the pack being used is recorded in the pattern reproduction order. In the case of an asynchronous pattern track, a combination of start timing data indicating the start time of the asynchronous pattern to be reproduced and reproduction pattern instruction data (pattern number) indicating the asynchronous pattern to be reproduced from the pack being used. Are recorded in the pattern playback order.
[0058]
FIG. 8 is a diagram showing a configuration example of music data created by performance pattern development in a music creation application according to an embodiment of the present invention. In the music creation application, music data having a data format that can be reproduced by a plurality of mobile phone types can be created based on the pattern sequence data as shown in FIG. As shown on the left side of FIG. 8, the music data includes a music data identifier, first track data, second track data, third track data, WAVE pack data, and music end data.
[0059]
The first to third track data includes a track identifier, an edit flag, a transfer flag, event sequence data, and track end data, as shown in the upper center of FIG. Typically, the first and second track data correspond to the first and second track data of the synchronous pattern, and the asynchronous pattern track data corresponds to the third track data. The event sequence data in the first to third track data is slightly different when it is created from a synchronous pattern track and when it is created from an asynchronous pattern track.
[0060]
In the case of being created from the synchronization pattern track, as shown in the upper right part of FIG. 8, event data composed of processing timings and processing events are arranged in chronological order (data similar to MIDI). When created from an asynchronous pattern track, it is the same as the synchronous pattern when the asynchronous pattern is expressed in the MIDI-like format (upper right side of FIG. 8), but when the asynchronous pattern is expressed in the WAVE format, the lower right side of FIG. As shown in FIG. 5, event data including processing timing indicating a reproduction start time point and “event indicating WAVE to be reproduced” (WAVE instruction data) is arranged in time series.
[0061]
The WAVE pack in the music data is obtained by recording a plurality of WAVE data, and each WAVE data is composed of a WAVE number and a WAVE (waveform) as shown in the lower center of FIG. During reproduction, the WAVE data is read according to the instruction of the WAVE instruction data of the asynchronous pattern track (typically the third track) among the first to third tracks.
[0062]
[Operation example of OS processing]
FIG. 9 is a flowchart showing an operation example of OS processing in the portable terminal according to the embodiment of the present invention. The OS processing is repeated until the mobile terminal such as a mobile phone is turned on until it is turned off. In addition to the illustrated processing, the OS processing can process the basic operation of the mobile phone. it can. When the OS process starts, in step S1, if a pattern pack is received from the outside, each of the pattern packs is recorded in one of the memory areas that can be used in the external storage device 5.
[0063]
In the next step S2, upon receiving an instruction to start the music playback application, the music playback processing is activated. In this music reproduction process, music is assembled and reproduced in real time by sequentially selecting the performance patterns of the pack.
[0064]
In the subsequent step S3, a music (editing) creation process is activated in response to an instruction to start the music creation application. When the music creation application is executed, a screen (FIG. 6) for creating and editing music (creating and editing a pattern sequence) is displayed on the display. In the music (editing) creation process, using this screen, the performance patterns selected from the pack are arranged in the order of reproduction, whereby the music is assembled and a pattern sequence or music data is created.
[0065]
[Music playback application processing procedure]
FIG. 10 and FIG. 11 are flowcharts showing operation examples of music reproduction processing and music reproduction interruption processing according to one embodiment of the present invention. The music playback process in FIG. 10 and the music playback interrupt process in FIG. 11 operate according to the music playback application program. The music playback process in FIG. 10 is performed after an instruction to start the music playback application program is issued. Even if the music playback process is activated until it is instructed to stop, the music playback process is temporarily performed when there is a command to execute the original operation of the mobile terminal such as a call process. It is stopped and the operation based on this command is executed.
[0066]
In FIG. 10, when the music playback mode is entered by operating the mode switch 6m, the music playback processing starts, and a pattern pack that can be used for playback is displayed on the display 11d. First, in the first step R1, it is determined whether or not a pattern pack used for pattern reproduction is newly selected. When there is a pattern pack selection operation (new pack selection operation using the keys 6c and 6e) (R1 → YES), the process proceeds to Step R2, and the selected pattern pack is set as a reproduction pattern pack. Next, in step R3, the pattern of the reproduction pattern pack is set as a reproduction pattern.
[0067]
Steps R2 and R3 described above are steps for setting or changing the pattern to be assigned to the pattern assignment / instruction switches SW1 to SW12 in accordance with the selection of the pattern pack. That is, in step R2, the pattern pack (one data) newly selected for reproduction is read from the memory area (ROM 3 or external storage device 5) and written to a predetermined buffer in the RAM 4. In the next step R3, a plurality of patterns contained in the selected pattern pack for reproduction are separated for each pattern end data, and each pattern is used as a reproduction pattern to be used in a reproduction operation. Assigned to the corresponding one of SW1 to SW12, the selected pattern pack number and the pattern number assigned to each switch SW1 to SW12 are written into the assignment state buffer. (See Figure 3)
[0068]
When it is determined in step R1 that a new pack selection operation has not been performed (R1 → NO) and after the processing in step R3, the process proceeds to step R4, and any pattern is selected by operating the pattern assignment / instruction switches SW1 to SW12. Is selected, and if there is a pattern selection operation (R4 → YES), the routine proceeds to step R5, where it is further determined whether the selected pattern is already being reproduced.
[0069]
If the selected pattern is not being reproduced (R5 → NO), an instruction to newly start reproduction of the selected pattern is set in step R6. This setting is made by registering the pattern number of the pattern instructed to start reproduction anew in the start buffer in the RAM. For example, as shown in FIGS. 5 (1) to (3) and (6), when “Pattern 1”, “Pattern 7”, or “Pattern 2” that is not being reproduced is selected, the reproduction of the pattern is newly started. The pattern numbers “1”, “7”, and “2” are registered in the start buffer. If the current pattern reproduction start instruction is made in a state where no pattern is reproduced as shown in FIG. 5A, the timer 2 for measuring the reproduction time is reset.
[0070]
On the other hand, if the selected pattern is already being reproduced (R5 → YES), an instruction to stop the reproduction of the selected pattern is set in step R7. This setting is made by registering the pattern number of the pattern instructed to stop in the stop buffer in the RAM. For example, as shown in FIG. 5 (5), when “Pattern 1” is selected again during playback of “Pattern 1”, it is determined that playback of “Pattern 1” should be stopped, and the stop buffer Is registered with the pattern number “1”. Note that when the replaying pattern selected again is an asynchronous pattern as shown in “Pattern 7” in FIG. 5 (7), the selection operation for the pattern becomes invalid.
[0071]
Control of the start and stop of pattern reproduction set in steps R6 and R7 and control of event processing based on the start of pattern reproduction are executed in a music reproduction interruption process (FIG. 11) described later.
[0072]
When there is no pattern selection operation (R4 → NO) and after the processing of Steps R6 and R7, the process proceeds to Step R8, and if there is an instruction to stop the music playback application, the playback processing is stopped and the music playback processing is ended. If there is no such stop instruction, the process returns to step R1, and the above-described operations of steps R1 to R7 are repeated until a stop instruction is issued.
[0073]
The music playback interrupt process of FIG. 11 operates by interrupting the playback process while the music playback application is activated, and the interrupt cycle is determined by the resolution of event reading of the asynchronous pattern and the synchronous pattern. It is a short interval. In this music reproduction interruption process, whether there is a pattern to start or stop the reproduction is determined with reference to the start buffer and the stop buffer in the RAM 4. That is, the pattern registered in the start buffer is a pattern for newly starting reproduction, and the pattern registered in the stop buffer is a pattern for newly stopping reproduction. Whether the pattern type is a synchronous pattern or an asynchronous pattern can be determined from the pattern number of the pattern.
[0074]
In FIG. 11, when the music reproduction interruption process starts, in the first step R51, the event at the current timing is read and reproduced for the synchronous pattern and asynchronous pattern being reproduced. For example, in FIG. 5, an event of each interrupt timing is read for “pattern 1” in the sections ta to tb and tb to tc, and each interrupt timing is set for “pattern 2” in the sections tb3 to tc, tc to td, td to. In the interval t2 to t4, t6 to..., The event at each interrupt timing is read for “pattern 7”.
[0075]
Subsequently, at steps R52 and R53, asynchronous pattern reproduction start and reproduction stop processing are performed. First, in step R52, if there is an asynchronous pattern instructed to start reproduction, the asynchronous pattern starts to be read from the first event. For example, as shown in FIGS. 5 (2) and (6), when the reproduction start of “pattern 7” which is an asynchronous pattern is instructed, reading of these patterns is started from the top event.
[0076]
Subsequently, in step R53, reading (reproduction) is stopped for the asynchronous pattern being reproduced from which the event has been read to the end of the pattern. That is, the reproduction of the asynchronous pattern is automatically stopped when one reproduction is completed. For example, in FIG. 5, the reading of “pattern 7” is stopped at timing t4 when the event is read to the end of the asynchronous pattern “pattern 7”. If the asynchronous pattern assigned to the selected asynchronous pattern assignment / instruction switch (SW7 to SW12) is being reproduced, this selection operation becomes invalid, and the asynchronous pattern is automatically set regardless of the selection operation. (See FIG. 5 (7)).
[0077]
Next, in step R54, it is determined whether or not the current timing is the timing of a beat or a bar line. If it is this timing, the process proceeds to steps R55 and R56 sequentially to start and stop playback of the synchronization pattern. I do. That is, the reproduction start and reproduction stop of the synchronization pattern are performed in synchronization with the beat timing (tb3, etc.) or the bar line timing (ta, tb,...). In addition, the synchronization pattern is returned to the beginning when the reproduction for one time is finished, and the reproduction is continued. The synchronization pattern assignment / instruction switches (SW1 to SW6) to which the pattern being reproduced is assigned are pressed again. Playback is repeated until a playback stop instruction is given.
[0078]
First, in step R55, if there is a synchronization pattern instructed to start reproduction, reading (reproduction) is started from an event corresponding to the current timing of the pattern. For example, in the case of FIG. 5 (1), “Pattern 1”, which is a synchronization pattern, is instructed to start or continue playback at the bar line timing ta (= t1) and tb, and starts reading from the head position. Is done. In the case of FIG. 5 (3), since the reproduction start of the “pattern 2” which is the synchronization pattern is instructed at the timing t3, the third and subsequent beats of the “pattern 2” at the next beat timing tb3. Event reading is started, and reading from the head position by an instruction to automatically continue playback is started at the bar line timings tc and td.
[0079]
Subsequently, in step R56, if there is a synchronization pattern instructed to stop reproduction, reading (reproduction) of the event of that pattern is stopped. In other words, when an instruction to stop playback is given, the synchronization pattern is stopped in synchronization with the timing of the first beat or bar line after the instruction is given. For example, the bar line timing tc in FIG. 5 is the first beat or bar line timing after the time point (t5) when the instruction to stop playback of “Pattern 1” is given. Therefore, playback of “Pattern 1” is performed at this timing tc. Is stopped.
[0080]
Then, when it is determined that the current timing is not the beat or bar line timing (R54 → NO) and after the process of step R56, the current music reproduction interruption process is terminated and the next interrupt timing is awaited.
[0081]
[Music creation application processing procedure]
12 and 13 are flowcharts showing an operation example of the music composition (editing) process according to one embodiment of the present invention, and FIG. 14 is a flowchart showing an operation example of the performance pattern developing process according to one embodiment of the present invention. It is. These processes related to music creation operate according to the music creation application program.
[0082]
The music creation (editing) process of FIGS. 12 and 13 is repeated until there is an instruction to start the music creation application program and an instruction to stop the music creation application program. Even if the (editing) process is activated, when there is a command to execute the original operation of the portable terminal such as a call process, the musical tone reproduction process is temporarily stopped, and an operation based on this command is executed.
[0083]
In FIG. 12, when the music creation mode is entered by operating the mode switch 6m, the music creation (editing) process starts, and a pattern pack that can be used for music creation (editing) is displayed on the display 11d. The pattern packs displayed here only include patterns that can be edited (patterns whose edit flag is set to “editable”). First, in step E1, it is determined whether or not a pattern pack to be used for music creation has been newly selected.
[0084]
When a pattern pack selection operation is detected (E1 → YES), the process proceeds to steps E2 and E3 in sequence, and similarly to steps R2 and R3 of the reproduction process, setting of a pattern to be assigned to the pattern assignment / instruction switches SW1 to SW12 or Change the settings. That is, in step E2, the selected pattern pack is set as a pattern pack for creation. In step E3, the pattern of the set pattern pack for creation is set as a pattern for creation. Store in the allocation status buffer. The pattern assigned to the switch is only the pattern in which the edit flag in the selected pack is set to “editable”.
[0085]
In the next step E4, the pattern pack number of the pattern sequence being created is changed. That is, the pattern number recorded in the pattern sequence being created is left as it is, and only the setting of the pattern pack to be used is changed. As described above, the contents of the pattern sequence can be changed to another piece of music just by changing the pattern pack number. Note that all pattern packs have the same configuration and contain the same number of synchronous patterns and asynchronous patterns, and the pattern numbers of the synchronous patterns and asynchronous patterns are the same. For example, the pattern pack includes 12 patterns, patterns 1 to 6 are synchronous patterns, and patterns 7 to 12 are asynchronous patterns.
[0086]
When the pattern pack selection operation is not detected (E1 → NO) and after the processing in step E3 or step E4 (the pattern pack number change in step E4 is applied as necessary), in step E5, Using the pattern sequence creation (edit) screen (FIG. 6), a track for writing a predetermined pattern, a start timing, and a playback length (end timing) are set. That is, a pattern writing section WA (shaded portion) having a desired length is set at a desired location in a desired pattern display field (TS1, TS2, TA) on the creation (edit) screen.
[0087]
In a subsequent step E6 (FIG. 13), it is determined whether or not a pattern to be written in the set pattern writing section WA has been selected. When it is detected that a pattern to be written in the pattern writing section WA is selected (operation of the switches SW1 to SW12), it is further determined in step E7 whether or not the selected pattern is a synchronous pattern. To do.
[0088]
Here, if it is a synchronization pattern (E7 → YES), in step E8, the selected synchronization pattern starts to be read from the event corresponding to the first beat timing of the section, and is repeatedly reproduced within the set section WA. Is written in the corresponding track, and the selected pattern is displayed in the setting section WA instead of the shaded area. On the other hand, if it is an asynchronous pattern (E7 → NO), in step E9, the instruction data for reproducing the set asynchronous pattern only once from the start timing (start time of the section WA) is written to the corresponding track, and the set section WA The selected pattern is displayed instead of the shaded area.
[0089]
When a pattern selection operation for the pattern writing section WA is not detected (E6 → NO) and after the processing of Steps E8 and E9, the process proceeds to Step E10 to determine whether or not it is instructed to create music data To do. The music data is data in a format that can be reproduced in common by a plurality of portable terminals. Here, when there is an instruction to create music data, the performance pattern development process (FIG. 14) is performed in step E11, and then the process proceeds to step E12. Otherwise, the process immediately proceeds to step E12.
[0090]
In step E12, processing such as reproduction of music data or transmission to the outside is performed in accordance with the instruction. Thereafter, if there is an instruction to stop the music creation application, the music creation (editing) process is terminated. If there is no such stop instruction, the process returns to step E1, and the above-described operations of steps E1 to E12 are repeated until a stop instruction is issued. The music data that can be transmitted to the outside is only those for which the transfer flag is set to “transferable”.
[0091]
FIG. 14 shows a specific flow example of the performance pattern development process executed in step E11 (FIG. 13) of the music creation (editing) process. By this development processing, event format music data that can be reproduced in common by a plurality of types of information devices including mobile terminals such as mobile phones is obtained, and the obtained music data does not accumulate various performance patterns. It can be used as it is in other information devices.
[0092]
When this processing flow starts, first, in a first step E31, all synchronization pattern tracks are converted into event sequence format data, and event sequence format track data corresponding to the synchronization pattern track is created. In other words, event data is read from the pattern along the instruction data of the synchronization pattern track, new timing data is created, and the timing data and event data are recorded as an event sequence as shown in the upper right part of FIG.
[0093]
In the next step E32, track data corresponding to the asynchronous pattern track is created. Asynchronous patterns include data in WAVE format and MIDI-like format, and data in MIDI-like format is expanded into an event sequence (similar to the upper right side in FIG. 8) as in the case of the synchronous pattern track processing in step E31. ). For WAVE format data, in the event sequence developed in a MIDI-like format, instruction data for instructing reading of WAVE format data is shown in the format shown in the lower right part of FIG. Record in position.
[0094]
Next, in step E33, an edit flag “not editable” and a transmission flag “transmittable” are added to all the created track data. The entry of the “non-editable” flag controls the created music data so that it cannot be edited, and the result data obtained by the individual user creation (editing) can be effectively protected. Further, since the created music data can be transmitted to an external device by filling in the “transmission enabled” flag, it can be used effectively in other information devices such as other mobile phones.
[0095]
In subsequent step E34, the WAVE pattern used for the asynchronous pattern track is read out, and a configuration WAVE pack composed of a plurality of WAVE data (see the lower center portion in FIG. 8) is created.

[Various Embodiments]
Although one embodiment has been described above, various embodiments can be applied. For example, the assignment of performance patterns to the switches (SW1 to SW12) has been determined in advance in the embodiment, but a means for setting how to assign the performance patterns to the switches may be provided to allow the user to set it. Good.
[0097]
A plurality of performance patterns may be assigned to one switch. In that case, a plurality of assigned patterns may be selected in order each time the switch is operated.
[0098]
The method for determining the type of each performance pattern (synchronous pattern / asynchronous pattern) does not have to rely on the pattern number, and any method can be used as long as the type can be determined. For example, a method of recording type data representing a type for each pattern, a method of determining a pattern type by referring to a pattern recording format, and the like are conceivable.
[0099]
Although the performance pattern is one measure long, it may be shorter or longer. Moreover, although each pattern was made into the same length, it is good also as a different pattern length.
[0100]
When creating a song, you can write to the specified track as if the switch (SW7 to SW12) to which the asynchronous pattern was assigned was pressed while the track (display field TS1, TS2) of the synchronous pattern was selected When a switch having a non-pattern is operated, the operation can be ignored or can be automatically written to a writable track different from the designated track.
[0101]
Tracks created using the asynchronous pattern display field (TA) may be divided into two tracks, that is, a track composed of an event sequence and a track composed of instruction data by providing two display columns.

【The invention's effect】
As described above, according to the present invention, a plurality of performance patterns are prepared in order to edit music in music creation (editing) on a portable terminal, and performance patterns are assigned to switch operators such as a numeric keypad. And assign it to function as a “pattern assignment / instruction switch”, and specify the timing at which the performance pattern should be reproduced at a musical break position (beat or bar line, etc.) on the time axis or a time position finer than the break position, By selecting a performance pattern by operating the controls, a pattern sequence is created in which the data for specifying the selected performance pattern is arranged in the playback order according to the specified musical break position and fine time position. This allows you to create a variety of music with a simple operation on your mobile device. Since the choice has followed the conventional operability use the switch operator, such as a numeric keypad that is provided to the portable terminal, it is possible to easily adapt to the editing operation.
In particular, according to the music editing according to the first feature of the present invention, a performance pattern composed of "MIDI-like" data representing a pronunciation instruction is prepared, and musical delimiter positions and fine time positions are set. When a specified operator is operated, a pattern sequence is generated that instructs the performance pattern assigned to the operator to be played back at a timing corresponding to the specified musical break position or fine time position. As a result, a variety of music can be created in which a performance pattern in the “MIDI-like” format is sequentially played back at a musical delimiter position or a detailed timing position with a simple operation on a portable terminal. .
According to the music editing according to the second feature of the present invention, the performance pattern in the first format composed of “MIDI-like” data representing the pronunciation instruction and the data in “WAVE” format representing the sound waveform are constructed. A plurality of performance patterns of the second format are prepared in advance, and for the performance pattern of the first format (“MIDI-like” format), a musical delimiter position and a fine temporal position are designated and the corresponding operation element is designated. When the operation pattern is designated for the performance pattern in the second format and the corresponding operation element is operated, the performance pattern assigned to the operation pattern is in the first format (“MIDI similar” format). In the case of the second format ("WAVE" format), the specified fine temporal position is used so that the playback is performed at a timing corresponding to the specified musical break position and fine temporal position. Since a pattern sequence to be instructed is created so as to be played back at a timing corresponding to the above, a musical operation delimitation position can be obtained for a performance pattern of “MIDI similar” format by a simple operation on a portable terminal. With regard to the performance pattern of the “WAVE” format, various musical pieces that are sequentially played back can be created at a fine time position timing.
Furthermore, according to the music editing according to the third feature of the present invention, the first type performance pattern called “synchronization pattern” that is reproduced in synchronization with the musical break position and “asynchronous” that is reproduced at an arbitrary timing. A plurality of second type performance patterns called “patterns” are prepared, and the first type performance pattern (synchronization pattern) is designated by specifying a musical delimiter position and operating the corresponding operator. For a type of performance pattern (asynchronous pattern), if a specific time position is specified and the corresponding control is operated, the specified music is played if the performance pattern assigned to the control is the first type (synchronous pattern). In the case of the second type (asynchronous pattern), the specified fine time so that the performance pattern is reproduced in synchronization with the timing corresponding to a specific break position. Each instruction sequence is created so that it can be played back at the timing corresponding to the position. By changing the timing, the first type performance pattern (synchronized pattern) is synchronized with the timing of the musical delimiter position, and the second type performance pattern (asynchronous pattern) is sequentially played back at the timing of the fine temporal position. A variety of music can be created.
[0103]
According to the present invention, a plurality of performance patterns are placed in a pack, which is a minimum storage unit that can be individually recognized by the mobile terminal OS, in the storage means of the mobile terminal, and the performance patterns assigned to the operators by selecting the pack. Thus, a desired performance pattern is selected from the selected desired pack by operating the operator, and a desired pattern sequence in which pattern designating data indicating the performance pattern is arranged is created. Can do.
[0104]
According to this invention, a musical sequence break position (beat or bar line etc.) on the time axis and a time position finer than the break position are displayed and displayed on the pattern sequence creation (edit) screen of the display of the portable terminal. By specifying the musical break position and the fine time position, the timing at which the performance pattern should be reproduced can be easily specified.
[0105]
According to the present invention, when the pattern sequence in which the pattern instruction data indicating the performance pattern selected by the operation of the switch is arranged in the reproduction order corresponding to the predetermined timing is created, this pattern sequence is stored in the pattern instruction data. In accordance with the instructions, the performance patterns recorded in the storage means of the portable terminal are sequentially developed and changed to music data. This music data is event-format data that can be reproduced in common by a plurality of types of information devices including mobile terminals such as mobile phones. Therefore, in other information devices that do not store various performance patterns, Can be used.
[0106]
Since this music data can be transferred to other information devices with transfer permission information added, it can be used effectively in other information devices. In addition, since the music data is set so that the editable information is added and the music data cannot be edited, the result data obtained by the user's creation (editing) work can be effectively protected.
