Therefore, one music can be created by a simple operation. In addition, since a switch such as a numeric keypad provided in the mobile terminal is used for selecting the playing pattern, the conventional operability is followed and the editing operation can be easily adapted.

In the pattern sequence (FIG. 7) created by the music editing apparatus in the portable terminal of the present invention, when the performance pattern assigned to the operator (6s) is a synchronous pattern, musical timing (ts1 , Ts2

Therefore, a variety of musical pieces can be easily created by changing the arrangement order of the performance patterns or the type of the performance patterns.

According to the present invention, the storage means (3, 5) includes
A plurality of performance patterns are contained in a pack, which is the minimum storage unit that can be individually recognized by the mobile terminal OS (Operating System) (“pattern pack”), and the performance pattern assigned to the switch is determined by selecting the pack. At the same time, a pack changing means (E4) is provided. By selecting a desired performance pattern from the selected desired pack, a pattern sequence (FIG. 7) in which pattern designating data (pattern numbers) designating the performance pattern is arranged is created. Also, pack changing means (E4)
Thus, when the pack (number) of the already created pattern sequence (FIG. 7) is changed, the content of the pattern sequence can be changed to another music without changing the pattern instruction data (pattern number). In other words, by changing the type of the pack, the existing performance pattern array can be diverted to edit a new music piece, which contributes to the creation of various music pieces and further promotes the motivation of music piece creation.

According to the second aspect of the present invention, the pattern instruction data (pattern number) for instructing the performance pattern selected by operating the switch (6s, 6a) has a predetermined timing (ts1, ts2, ... Ta1, pattern sequence arranged in reproduction order corresponding to ta2, ...) (FIG. 7)
When the pattern sequence is created, this pattern sequence is converted into music data (FIG. 8) in which the performance patterns recorded in the storage means (3, 5) of the portable terminal are sequentially expanded in accordance with the instruction of the pattern instruction data (pattern number).

Since this music data is event format data that can be played back in common by multiple types of information devices including mobile terminals such as mobile phones, it can be used as is in other devices that do not store various performance patterns. can do.

In the obtained music data, transfer availability information (transfer flag or transfer bit) is set to transfer enabled,
It can be transferred to other information devices such as mobile phones. In other words, the original data before editing, such as performance patterns, is usually set to be not transferable, but the music data obtained by editing is changed to transferable so that it can be used effectively in other information devices. Can be used.

Further, in the obtained music data, editability information (edit flag or transfer bit) is set to uneditable, and the music data is set to be uneditable. In other words, original data such as performance patterns before editing is usually set to be editable, but by changing the song data obtained by editing to not editable,
The individual achievement data of the user can be effectively protected.

Random access memory (RAM) 4 for temporarily holding control and processing data, storage device such as an external storage device 5 including a recording medium such as a semiconductor memory and functioning as a memory for storing various data are provided.

Various data and application programs relating to the music reproducing and creating application according to the present invention can be recorded in a memory such as the ROM 3 to the external storage device 5. For example, performance pattern data (also simply referred to as “pattern”), pattern sequence data, music data, etc. used in a music reproduction and creation application are recorded, and the performance pattern and pattern sequence data are stored in storage units called “pattern packs”. Will be recorded.

As the input means, an operator circuit (operation unit) 6 for inputting required information to the terminal system based on various input operations by operators such as pattern assignment / instruction switches (6s, 6a), user's voice, etc. And a microphone circuit 7 for inputting. The radio wave transmitter / receiver 8 controlled by the CPU 1 transmits / receives a call sound signal and a data signal to / from another communication terminal, a server or the like via the antenna 9. Voice signals such as incoming call sound signals are sent to the CPU
Under the control of 1, the user listens to the voice through the voice speaker circuit (receiver) 10.

A 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 / processes of the mobile terminal including transmission and reception. The portable terminal is further provided with a tone signal generation circuit 12 including a tone generation sound source and a sound system 13 including a tone speaker (sounder) in order to emit a 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 equipment such as a personal computer (PC).

This mobile terminal is equipped with a radio wave transmitter / receiver 8 and a communication I
/ F14 can be used to connect to external devices such as servers on the Internet and other information processing devices.
It is possible to acquire a pattern pack from an external device and distribute the music data created by this mobile terminal to the external device.

[Basic Operation of System and Pattern Pack] In a mobile terminal such as a mobile phone to which the present invention is applied, the relationship between an OS (system program) and an application program installed in the mobile terminal is a terminal power supply. The OS is always running while is turned on.
A plurality of application programs are executed on this OS. Therefore, the music reproducing process and the music creating (editing) process according to the present invention correspond to one of such application programs.

Regarding the handling of data in such a portable terminal, the memory is divided into a plurality of areas, and one area has one area.
Only data can be recorded. Also, the number of data that can be managed by the OS is fixed, and the number of memory areas is
This is the maximum number of data that can be managed by.

In one embodiment according to the present invention, the playing pattern used in the music reproducing and creating application is devised to handle such basic operating conditions in the portable terminal, and a plurality of pattern data is used. (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 each "pattern pack" is included. O for all pattern data
In addition to making S recognize as one data, application program [music reproduction processing and music creation (editing)
By processing], pattern data management such as taking out a plurality of pattern data from one "pattern pack" is performed, thereby enabling efficient use of the memory.

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. , 12 patterns are recorded in one memory area as one pack (one data), the remaining capacity of the memory area is 1 in one memory area.
Compared with the case where only the pattern is recorded as one data, the number is obviously reduced, and the memory usage efficiency can be greatly improved.

FIG. 2 shows an example of the structure of a pattern pack used in a music reproducing and creating application according to an embodiment of the present invention. A plurality of pattern packs are used in the music reproducing and creating application, 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 has a pack number and performance pattern data (performance pattern, pattern), respectively.
And pack end data, the OS recognizes the information from the pack number to the pack end as one data.

Further, as shown on the right side of FIG. 2, one pack contains a plurality of performance pattern data. The performance pattern data is data for reproducing a music piece of about one measure, and is used as segment data for assembling a music piece. Each performance pattern data is composed of a pattern number, an edit flag, a transfer flag, event sequence data and pattern end data. On the other hand, the musical sound reproduction and creation (editing) application recognizes each pattern information from the pattern number to the pattern end data as one pattern. For example, 12 pattern data "Pattern 1" to "Pattern 12" are contained in one pattern pack,
In the following, description will be given according to an example of these 12 patterns.

Here, the plurality of patterns contained in one pattern pack are created with musical relevance. For example, a plurality of patterns included in one pattern pack are created in accordance with the same musical genre (rock, jazz, pops, etc.), the same singer, the same composer, and the like. In addition, a plurality of patterns contained 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 6" is the synchronization pattern, and "Pattern 7"
~ "Pattern 12" is an asynchronous pattern.

The sync pattern is pattern data whose reproduction is started in synchronization with a musical break position such as a beat or bar line. Similarly to the so-called MIDI format, the event sequence data of the synchronization pattern is data in which the events representing the sounding instruction commands for the tone generation sources of the tone signal generation circuit 12 are recorded in the order of performance progress.
It is called "MIDI-like" format data.

The asynchronous pattern is pattern data in which the reproduction is immediately started at the timing of the reproduction instruction. For the event sequence of the asynchronous pattern, not only the data of the same "MIDI-like" format as the synchronous pattern but also the data of the "WAVE" format can be used. The “WAVE” format data is data in which events representing discrete values at each sampling timing of a musical tone waveform are recorded in the order of performance progress, and is not limited to pure musical tone information of musical instruments and the like, but also voice and natural sounds (effects). Sound) such as musically available sound information.

[Configuration of allocation buffer and operation / display unit]
FIG. 3 shows a configuration example of an allocation state buffer used in a music reproduction and creation application according to an embodiment of the present invention. In the music reproduction and creation application, the allocation status buffer provided in the RAM 4
As shown in FIG. 3, the pack number of the currently selected pattern pack and the pattern number assigned to each of the pattern assignment / instruction switches SW1 to SW12 of the operation unit 6 are stored. In the illustrated example, the pack number (PAC
K) The pattern pack of "3" is currently selected and the pattern numbers "1", "2", "3", ..., "12" are assigned to the switches SW1, SW2, SW3, ..., SW12, respectively. The pattern data corresponding to the pattern number of the switch can be selected by operating the switches SW1 to SW12.

FIG. 4 shows a switch configuration example of the portable terminal according to the embodiment of the present invention. On the operation surface of a mobile terminal such as a mobile phone, as shown in FIG.
And various switches / keys 6m, 6c, 6e, 6s, 6a
Is provided, and an antenna pole 9p is provided at the upper end of the case. The mode switch 6m has a function of sequentially switching the operation mode of the mobile terminal each time it is operated. For example, when the music reproduction mode is entered by operating the mode switch 6m, the display 11d records this mobile terminal. All pattern packs are displayed by pack name or pack number.

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 keys 6c such as "▲" and "▼". ENT
The pattern pack to be used can be selected and determined by operating the ER "key 6e. In the music playback mode or the music creation (editing) mode, the numeric keypad, the" * "key and the"#"key , Which functions as the above-described pattern assignment / instruction switches SW1 to SW12. Of course, this numeric keypad functions as a switch for inputting a numerical value such as a telephone number in a normal mode for making a call.

The "1" to "6" keys in the numeric keypad are the above-mentioned switches SW1 to SW6, and the synchronization patterns corresponding to the pattern numbers "1" to "6" in the pattern pack are assigned one by one, It belongs to the synchronization pattern assignment / instruction key 6s for instructing each synchronization pattern.

The "7" to "0" keys on the numeric keypad,
The "*" key and the "#" key are used for the above-mentioned switches SW7-
SW12 (“*” → SW10, “0” → SW11,
“#” → SW12) and pattern numbers “7” to “1”
Asynchronous patterns corresponding to 2 "are assigned one by one and belong to the asynchronous pattern assignment / instruction key 6a for instructing each asynchronous pattern.

[Outline of Musical Sound Reproduction] FIG. 5 is a diagram showing an operation example of pattern reproduction in a music reproduction application according to an embodiment of the present invention. In this figure, the time axis is taken as the horizontal axis, and long vertical lines represent bar line timings ta, tb, tc, td, ... Corresponding to bar lines. The short vertical line represents the beat timing, and, for example, the beat timing tb3 is the third beat timing in the measure section between the measure timings tb and tc.

An outline of this music reproduction will be described with reference to FIG. 5. A performance pattern is assigned to each of switch operators 6s and 6a such as a numeric keypad provided in a mobile terminal such as a mobile phone, and the switches SW1 and SW1 are sequentially arranged. SW7, S
When W2, ... Is operated (t1, t2, t3, ...), the performance pattern “1”, which is assigned to each switch,
“7”, “2”, ... Are reproduced in real time. There are a plurality of playing patterns to be played in each pack, which is the minimum information unit that can be handled individually by the OS installed in the mobile terminal. The performance pattern to be assigned is determined. Performance patterns stored in each pack include a synchronous pattern and an asynchronous pattern, and the synchronous patterns “1”, “2”, ...
1, t3, ... Musical timing after ta, tb3
The reproduction is started at ..., and the asynchronous pattern "7", ... is immediately started at the switch operation timing t2 ,.

In the following, referring to FIG. 5, the pattern reproduction is performed when the mode switch 6m is operated to enter the music reproduction mode and the cursor key 6c is operated to select a certain pack, and then the pattern allocation / instruction switches SW1 to SW12 are operated. An operation example will be described step by step for each of the following events (1) to (7). In this operation example, for convenience, all patterns used in the music reproducing process are described as one bar length, the synchronization pattern is data in MIDI-like format, and the asynchronous pattern is data in WAVE format. 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, and "pattern 1" and "Pattern 2" is a synchronous pattern and "Pattern 7" is an asynchronous pattern.

(1) First, at a certain timing t1, the first switch SW1 of the synchronization pattern allocation / instruction key 6s
When the ("1" key) is pressed, "pattern 1" of the pattern pack starts to be read from the first event, and reproduction of this pattern data is started. 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) to measure the reproduction time. Start. That is, the timer 2 is reset at this timing t1.

(2) When the first switch SW7 ("7" key) of the asynchronous pattern assignment / instruction key 6a is pressed at timing t2, the timing t2 at which this switch SW7 is pressed is either beat timing or bar line timing. However, since the “pattern 7” instructed by the switch SW7 is an asynchronous pattern, the “pattern 7” of the pattern pack is immediately operated at the operation timing t of the switch SW7.
At 2, the reading is started from the first event.

(3) At timing t3, the second switch SW2 ("2" key) of the synchronization pattern assignment / instruction key 6s.
When the switch SW2 is pressed, the timing at which the switch SW2 is pressed is neither the beat timing nor the bar line timing, and "Pattern 2" is a synchronization pattern. Therefore, the first beat timing tb after the timing t3 when the switch SW2 is operated.
Until "3", the reproduction start of "Pattern 2" is awaited. Then, when the beat timing tb3 immediately after the operation arrives, the "pattern 2" is started to be read from an event (third beat event) corresponding to the beat timing tb3. Therefore, after this reading is started, a plurality of synchronization patterns "pattern 1" and "pattern 2" are reproduced in parallel.

(4) At the reproduction end timing t4 of the asynchronous pattern for one time, the reproduced asynchronous pattern is automatically stopped. In other words, the "pattern 7" that is an asynchronous pattern starts to be reproduced at the timing t2 and ends the reproduction for one time at the timing t4, so that the reproduction is stopped at the timing t4.

(5) When the synchronization pattern allocation / instruction switch SW1 is pressed at the timing t5, the switch SW1
Since the "pattern 1" corresponding to is being reproduced, and the operation for the synchronizing pattern being reproduced is interpreted as the stop of the reproduction of the pattern, it is determined that the stop of the reproduction of the "pattern 1" is instructed. However, since the timing t5 at which the switch SW1 is pressed is neither the beat timing nor the bar line timing, the reproduction of "Pattern 1" is stopped when the next beat or bar line timing tc arrives.

(6) When the asynchronous pattern allocation / instruction switch SW7 is pressed again at the timing t6, the "pattern 7" instructed by the switch SW7 is an asynchronous pattern, so at the timing t6 when the switch SW7 is operated. Immediately, reading is started from the first event of "pattern 7".

(7) When the asynchronous pattern allocation / instruction switch SW7 is pressed at the timing t7, the timing t
7 is a period during which the asynchronous pattern "Pattern 7" is being reproduced, so the operation of the switch SW7 at this timing is ignored.

[Outline of Music Creation (Edit)] FIG. 6 shows a display example of a pattern sequence creation (edit) screen in a music creation application according to an embodiment of the present invention. Music creation (editing) by operating the mode switch 6m
When the mode is entered, all pattern packs that can be used to create a pattern sequence are displayed on the display 11d by pack name, pack number, etc., as in the music reproduction mode. Therefore, the user operates the cursor key 6c to select the pack number to be used for creating the pattern sequence, and operates the "ENTER" key 6e to determine the pattern pack to be used for creating the pattern. As a result, a pattern sequence creation (editing) screen as shown in FIG. 6 appears on the display 11d.

The outline of the music creation (editing) will be described with reference to FIG. 6. A performance pattern is assigned to each of the switches 6s and 6a such as a ten-key pad provided in a mobile terminal such as a mobile phone. In the synchronous pattern display columns TS1 and TS2 or the asynchronous pattern display column TA of the pattern sequence creation (editing) screen, timings ts1 and t
When the pattern writing section WA is designated according to the scale indicating s2, ... Or the timings ta1, ta2, ... And a desired switch is selectively operated, the performance pattern assigned to the switch is associated with the section WA and selected. A pattern sequence is created that gives an instruction to reproduce the played performance pattern at the timing of the section WA. If the performance pattern is a sync pattern,
It is instructed to start the reproduction from the event corresponding to the designated timings ts1, ts2, ..., And in the case of the pattern asynchronous pattern, it is instructed to start the reading from the beginning at the designated timings ta1, ta2 ,.

More specifically, in the pattern sequence creation (editing) screen, the passage of time is taken along the horizontal axis,
A plurality of pattern display columns TS1, TS2, TA are arranged in the vertical direction, and these pattern display columns TS1, TS2,
A pattern sequence of a synchronous pattern and an asynchronous pattern can be expanded and displayed on the TA. In the screen example of FIG. 6, two sync pattern display columns TS1 are provided in the upper two rows.
TS2 is arranged, and the asynchronous pattern display field TA is arranged in the lower one row. First and second synchronization pattern display column T
The pattern sequences recorded on the first track and the second track of the synchronous pattern can be displayed in S1 and TS2, respectively, and the asynchronous pattern display field TA can
It is possible to display the pattern sequence recorded in the asynchronous pattern track. Note that the number of tracks (= the number of pattern display columns) can be appropriately increased or decreased according to the processing capacity of the mobile terminal.

In this screen example, each column TS1, TS2, TA is set so that the temporal position can be easily grasped.
A bar line LB is displayed across. Between the upper and lower stages, beat timings ts1, ts2, ...
A time scale indicating musical timing such as is displayed in correspondence with the synchronization pattern display columns TS1 and TS2, and a time scale indicating beat timing ts1, ts2, ... Finer musical timing ta1, ta2 ,. Is displayed corresponding to the asynchronous pattern display field TA.

In creating the pattern sequence, first, the cursor key 6c is operated to move each pattern display field T
After instructing S1, TS2, and TA, designating the starting point of the pattern in each column, the starting point of the pattern is determined by operating the "ENTER" key 6e. For the asynchronous pattern, only the starting point needs to be set by this method, but for the synchronous pattern, the ending point of the pattern is further specified by the cursor key 6c and the "ENTER" key 6e is used.

In this way, when the start point and the end point are determined and the pattern arrangement range is set, the set range is shaded, and this shaded portion WA is the writing portion of the new pattern set by the user. Represents Furthermore, the pattern assignment / instruction switches 6s, 6a (SW1 to SW1
When a switch corresponding to a pattern to be attached to this portion is selectively operated from 2), a desired pattern is expanded and displayed in the shaded portion WA. Then, the decision ("E
By operating the NTER ") key 6e, this pattern is recorded at the corresponding position of the corresponding track.

In FIG. 6, with respect to the illustrated time range, the first of the synchronization patterns in the pattern display columns TS1 and TA is displayed.
The pattern sequence of the track and the track of the asynchronous pattern has already been created, and in the second track of the synchronous pattern, “pattern 2” is written in a predetermined section of the second synchronous pattern display field TS2, and thereafter, for one beat. A shaded area indicates that a pattern writing section WA for writing a new pattern is set.

With respect to the synchronization pattern, the start and end points of the pattern writing section WA can be designated by the beat or bar line timings ts1, ts2, ... And are shown in "Pattern 2" of the synchronization pattern display column TS2. As described above, the bar is attached so as to match the bar line LB and the beat position of the set section. Regarding the asynchronous pattern, for example, as shown by the scale on the upper part of the asynchronous pattern display field TA, the start time of the pattern writing section WA is designated at the timing ta1, ta2, ..., which is finer than the beat timing ts1, ts2 ,. be able to.

FIG. 7 shows an example of the structure of pattern sequence data created by the music composition application according to an embodiment of the present invention. Create (edit) as shown in Figure 6

[Operation Example of OS Process] FIG. 9 is a flowchart showing an operation example of the OS process in the portable terminal according to the embodiment of the present invention. The OS process repeatedly operates from the time when the power of a mobile terminal such as a mobile phone is turned on to the time when the power is turned off. In addition to the illustrated process, the OS process may process the basic operation of the mobile phone. it can. This OS
When the process starts, in step S1, if a pattern pack is received from the outside, each of the pattern packs is recorded in each of the memory areas available in the external storage device 5.

In the next step S2, the music reproducing process is activated in response to the instruction to start the music reproducing application. In this music reproducing process, music is assembled and reproduced in real time by sequentially selecting the performance patterns of the pack.

Further, in the following step S3, the music (edit) creation process is activated in response to the 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 pattern sequence) is displayed on the display. In the music (editing) creation process, the screen is used to arrange the performance patterns selected from the pack in the order of reproduction, whereby the music is assembled and the pattern sequence or music data is created.

[Processing Procedure of Music Reproduction Application]
10 and 11 are flowcharts showing operation examples of the music reproduction processing and the music reproduction interruption processing according to the embodiment of the present invention. The music reproduction process of FIG. 10 and the music reproduction interrupt process of FIG. 11 operate according to the music reproduction application program. The music reproduction process of FIG. 10 is executed after an instruction to start the music reproduction application program is given. Even if the music playback process is activated until the instruction to stop, even if the music playback process is activated, when there is a command to execute the original operation of the mobile terminal such as a call process, this tone playback process is temporarily performed. Stopped,
The operation based on this instruction is executed.

In FIG. 10, when the music reproduction mode is entered by operating the mode switch 6m, the music reproduction process starts and the display 11d displays a pattern pack that can be used for reproduction. First, in the first step R1, it is determined whether or not a pattern pack used for pattern reproduction is newly selected. If there is a pattern pack selection operation (a 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 to the reproduction pattern.

The above-mentioned steps R2 and R3 are performed by the pattern assignment / instruction switch SW1 according to the selection of the pattern pack.
Is a step of setting or changing the pattern assigned to SW12. That is, in step R2, the pattern pack (1 data) newly selected for reproduction
Is read from the memory area (ROM 3 or external storage device 5) and written in a predetermined buffer in the RAM 4. Then, in the next step R3, the plurality of patterns contained in the selected reproduction pattern pack are separated for each pattern end data and separated, and each pattern is used as a reproduction pattern for the switch used in the reproduction operation. S
The selected pattern pack number and each switch SW1 to SW are assigned to the corresponding one of W1 to SW12.
The pattern number assigned to 12 and the assigned pattern number are written in the assignment state buffer. (See Figure 3)

When it is determined in step R1 that a new pack has not been selected (R1 → NO) and after the process of step R3, the process proceeds to step R4, in which the pattern allocation / instruction switches SW1 to SW12 are operated. If a pattern selection operation is performed (R4 → YES), the process proceeds to step R5, and it is further determined whether the selected pattern is already being reproduced. To be done.

If the selected pattern is not being reproduced (R5 →
NO), and in step R6, an instruction to newly start the reproduction of the selected pattern is set. In this setting, the pattern number of the pattern for which reproduction is newly instructed is stored in the RAM.
This is done by registering in the start buffer in. For example, as shown in (1) to (3) and (6) of FIG. 5, when "pattern 1", "pattern 7", or "pattern 2" which is not being reproduced is selected, reproduction of the pattern is newly started. It is determined that it should be performed, and the pattern numbers “1”, “7”, and “2” are registered in the start buffer. Further, if the instruction to start the pattern reproduction this time is given in the state where no pattern is reproduced as shown in FIG. 5A, the timer 2 for measuring the reproduction time is reset.

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. In this setting, the pattern number of the pattern instructed to stop is stored in the RAM.
This is done by registering in the stop buffer in. For example, as shown in FIG. 5 (5), when the "pattern 1" is already being reproduced and the "pattern 1" is selected again, it is determined that the reproduction of the "pattern 1" should be stopped, and the stop buffer is determined. The pattern number "1" is registered in. Note that FIG.
When the re-selected pattern being reproduced is an asynchronous pattern like the “pattern 7” of (7), the selection operation for the pattern is invalid.

The control of the start and stop of the pattern reproduction set in steps R6 and R7, and the control of the event processing based on the start of the pattern reproduction are executed in the music reproduction interrupt processing (FIG. 11) described later.

When there is no pattern selection operation (R4 →
NO) and after the processing of steps R6 and R7, step R
8. If there is an instruction to stop the music reproduction application, the reproduction processing is stopped and the music reproduction processing is terminated. If there is no such stop instruction, the process returns to step R1 and the above steps are performed until there is a stop instruction. The operations of R1 to R7 are repeated.

The music reproduction interrupt process of FIG. 11 operates by interrupting the reproduction process while the music reproduction application is activated, and the interrupt cycle is the event reading of the asynchronous pattern and the synchronous pattern. The interval is shorter than the resolution of. In this music reproduction interrupt process, whether or not there is a pattern to start or stop the reproduction is determined by referring 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 by the pattern number of the pattern.

In FIG. 11, when the music reproduction interrupt process starts, in the first step R51, the event at the current timing is read and reproduced for the synchronous pattern and the asynchronous pattern being reproduced. For example, in FIG. 5, in the sections ta to tb and tb to tc, the event at each interrupt timing is read for "pattern 1", and the section t
In b3 to tc, tc to td, td ..., the event of each interrupt timing is read for "Pattern 2",
In the sections t2 to t4, t6 and so on, the event at each interrupt timing is read for "pattern 7".

Then, in steps R52 and R53, processing for starting and stopping the reproduction of the asynchronous pattern is performed. First, in step R52, if there is an asynchronous pattern instructed to start reproduction, the asynchronous pattern is read from the first event. For example, in FIG.
As in (6), "pattern 7" is an asynchronous pattern
When the reproduction start of is specified, the reading of these patterns is started from the head event.

Then, in step R53, the reading (reproduction) is stopped for the asynchronous pattern being reproduced in which the event is read to the end of the pattern. That is, the reproduction of the asynchronous pattern is automatically stopped when the reproduction of one time is completed. For example, in FIG. 5, the reading of the "pattern 7" is stopped at the 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 is invalid, and the asynchronous pattern is automatically generated regardless of the selection operation. Stop control is performed (see FIG. 5 (7)).

Next, at step R54, it is judged whether or not the current timing is the timing of the beat or bar line, and if it is this timing, steps R55 and R56 are successively performed.
Then, the process for starting and stopping the reproduction of the sync pattern is performed. That is, the reproduction start and the reproduction stop of the synchronization pattern are performed at the beat timing (tb3 or the like) or the bar line timing (ta,
tb, ... Etc.). When the reproduction of the synchronization pattern is completed, the read position is returned to the beginning and the reproduction is continued, and the synchronization pattern allocation / instruction switches (SW1 to SW6) to which the pattern being reproduced is allocated are pressed again. Playback is repeated until a playback stop instruction is given.

First, in step R55, if there is a synchronization pattern instructed to start reproduction, reading (reproduction) is started from the event corresponding to the current timing of the pattern. For example, in the case of FIG. 5A, the synchronization pattern “Pattern 1” is the bar line timing ta.
At (= t1) and tb, an instruction to start or continue reproduction is given, and reading from the head position is started. Also, FIG.
In the case of (3), since the reproduction start instruction is issued at the timing t3 for the "pattern 2" which is the synchronization pattern, the event reading after the third beat of the "pattern 2" is performed at the next beat timing tb3. At the bar line timings tc and td, the reading from the head position is started by an instruction to automatically continue the reproduction.

Then, in step R56, if there is a synchronization pattern for which reproduction stop is instructed, the reading (reproduction) of the event of that pattern is stopped. That is, when the reproduction stop instruction is issued, 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.
When the instruction to stop the reproduction of "Pattern 1" is issued (t
5) Since it is the first beat or bar line timing after that,
At this timing tc, the reproduction of "Pattern 1" is stopped.

Then, when it is determined that the current timing is not the beat or bar line timing (R54 → NO) and after the processing of step R56, the current music reproduction interrupt processing is ended and waits until the next interrupt timing. .

[Processing Procedure of Music Composition Application]
12 and 13 are flowcharts showing an operation example of the music composition (editing) processing according to the embodiment of the present invention, and FIG. 14 is a flowchart showing an operation example of the performance pattern expansion processing according to the embodiment of the present invention. Is. These processes related to music creation operate according to the music creation application program.

The music composition (editing) processing of FIGS. 12 and 13 is repeatedly operated from the time the instruction for starting the music composition application program is given until the time it is instructed to stop the same, like the music reproduction processing. Even if music creation (editing) processing is activated, if there is an instruction to execute the original operation of the mobile terminal such as call processing, this musical sound reproduction processing is temporarily stopped and the operation based on this instruction is performed. Run.

In FIG. 12, when the music composition mode is entered by operating the mode switch 6m, the music composition (editing) process starts, and the display 11d displays a pattern pack that can be used for music composition (editing). The pattern packs displayed here include only patterns that are supposed to be editable (patterns whose edit flag is set to "editable"). First, in step E1, it is determined whether or not a pattern pack used to create a music piece is newly selected.

When the selection operation of the pattern pack is detected (E1.fwdarw.YES), the process sequentially proceeds to steps E2 and E3,
Similar to steps R2 and R3 of the reproduction process, the pattern assignment / instruction switches SW1 to SW12 are set or changed. That is, in step E2,
The selected pattern pack is set as a creation pattern pack, the pattern of the set creation pattern pack is set as a creation pattern in step E3, and the set pack and pattern are stored in the allocation state buffer. .
The pattern assigned to the switch is only the pattern in which the edit flag in the selected pack is set to "editable".

At the next step E4, the pattern pack number of the pattern sequence being created is changed. That is,
Leave the pattern numbers recorded in the created pattern sequence unchanged, and change only the settings of the pattern pack to be used. In this way, the content of the pattern sequence can be changed to another piece of music by simply changing the number of the pattern pack. It should be noted that all the 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 contains 12 patterns, patterns 1 to 6 are synchronous patterns, and patterns 7 to 12 are asynchronous patterns.

When the selection operation of the pattern pack is not detected (E1 → NO) and after the processing of step E3 or step E4 (the pattern pack number change of step E4 is applied if necessary), step E5 At
Using the pattern sequence creation (editing) screen (FIG. 6), a track to write a predetermined pattern, a start timing and a reproduction length (end timing) are set. That is,
A desired pattern display field (TS1,
A pattern writing section WA (shaded portion) having a desired length is set at a desired position of (TS2, TA).

In the following step E6 (FIG. 13), it is determined whether or not the pattern to be written in the set pattern writing section WA has been selected. When it is detected that the 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 the synchronization pattern. To do.

Here, if the pattern is a synchronization pattern (E7 → Y
ES), in step E8, the instruction data for starting to read the selected synchronization pattern from the event corresponding to the beat timing at the beginning of the section and repeatedly reproducing it in the set section WA is written in the corresponding track, and the set section WA is set.
, The selected pattern is displayed in place of shading. On the other hand, if it is the asynchronous pattern (E7 → NO), in step E9, the instruction data for reproducing the set asynchronous pattern only once from the start timing (the start time of the section WA) is written in the corresponding track, and the set section WA is set. , The selected pattern is displayed in place of shading.

When the operation of selecting the pattern 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, and it is determined whether or not the music data is instructed. To determine. The music data is data in a format that can be commonly played back by a plurality of mobile terminals. Here, when there is an instruction to create music data, the performance pattern development processing (FIG. 14) is performed in step E11, and then step E12.
Otherwise go to step E12 immediately.

In step E12, processing such as reproduction of music data and transmission to the outside is performed according to the instruction, and thereafter, if there is an instruction to stop the music creation application, this music creation (editing) processing is terminated. However, if there is no such stop instruction, the process returns to step E1 and the operations of steps E1 to E12 described above are repeated until there is a stop instruction. The only music data that can be transmitted to the outside is the one whose transfer flag is set to "transfer possible".

FIG. 14 shows a specific example of the flow of the performance pattern development processing executed in step E11 (FIG. 13) of the music creation (editing) processing. By this expansion processing, event-type music data that can be commonly played back by a plurality of types of information devices including mobile terminals such as mobile phones is obtained, and the obtained music data does not store various performance patterns. It can be used as it is in other information devices.

When this processing flow starts, first,
In the first step E31, all sync pattern tracks are converted into event sequence format data, and event sequence format track data corresponding to the sync pattern tracks are created. That is, the event data is read from the pattern in accordance with the instruction data of the sync pattern track, new timing data is created, and the timing data and the event data are recorded as an event sequence as shown in the upper right part of FIG.

In the next step E32, track data corresponding to the asynchronous pattern track is created. There are WAVE format data and MIDI similar format data in the asynchronous pattern. For MIDI similar format data, as in the processing of the synchronous pattern track in step E31,
Expand to an event sequence (similar to the upper right part of FIG. 8). For WAVE format data, WAVE format
The instruction data for instructing the reading of the format data is recorded at the corresponding position along the performance progress in the format shown in the lower right part of FIG.

Then, in step E33, an edit flag of "uneditable" and a transmission flag of "transmittable" are added to all the created track data. By writing the "uneditable" flag, the created music data is controlled so as not to be edited, and the result data obtained by the individual creation (editing) by the user can be effectively protected. Moreover, since the created music data is controlled so as to be transmitted to the external device by writing the “transmission possible” flag, it can be effectively used in other information devices such as mobile phones.

At the following step E34, the WAVE pattern used for the asynchronous pattern track is read to create a structured WAVE pack composed of a plurality of WAVE data (see the lower center of FIG. 8). Then, in step E35, the plurality of track data created and W
The AVE packs are put together to create one piece of music data (see the left side of FIG. 8), and this performance pattern development processing ends.

[Various Embodiments] Although one embodiment has been described above, various embodiments can be applied. For example, performance pattern switches (SW1 to SW1
Although the assignment to 2) is predetermined in the embodiment, a means for setting the assignment of the performance pattern to the switch may be provided so that the user can set it.

A plurality of performance patterns may be assigned to one switch. In that case, a plurality of assigned patterns may be sequentially selected each time the switch is operated.

The method of discriminating the type (synchronous pattern / asynchronous pattern) of each performance pattern does not have to depend on the pattern number, and any method can be used as long as the type can be discriminated. For example, a method of recording type data representing the type for each pattern, a method of referring to the pattern recording format by an application, and determining the type of the pattern can be considered.

The playing pattern is shown as one bar long, but it may be shorter or longer than this. Further, although the patterns have the same length, they may have different pattern lengths.

In the music creation, the switches (SW7 to S7) to which the asynchronous pattern is assigned although the tracks (display fields TS1 and TS2) of the synchronous pattern are selected.
When a switch whose pattern cannot be written to the specified track is operated, such as when W12) is pressed, the operation is ignored or a writable track different from the specified track is written. It can be automatically written in.

The track created by using the asynchronous pattern display field (TA) may be divided into two tracks, one of which is the event sequence and the other of which is the command data, by providing two of the display fields.

[0102]

As described above, according to the present invention, a performance pattern is assigned to each switch such as a ten-key pad provided in a mobile terminal such as a mobile phone to function as a "pattern assignment / instruction switch". By instructing the timing and operating the switch to select the performance pattern, a pattern sequence in which data instructing the selected performance pattern are arranged in the reproduction order is created. Therefore, one music can be created by a simple operation. In addition, since a switch such as a numeric keypad provided in the mobile terminal is used for selecting the playing pattern, the conventional operability is followed and the editing operation can be easily adapted.

In the created pattern sequence, when the performance pattern assigned to the operator (6s) is a synchronous pattern, musical timing (ts1, ts2,
...), the instruction data for starting the reproduction from the event corresponding to the timing is recorded, and the reproduction of the synchronous pattern is made to start only at the musical timing. In the case of the asynchronous pattern, the musical timing is started. At (ta1, ta2, ...), the instruction data for starting the reading from the beginning is recorded, and the asynchronous pattern is reproduced.
It can be started at any timing. Therefore, a variety of musical pieces can be easily created by changing the arrangement order of the performance patterns or the type of the performance patterns.

Further, in the storage means, a plurality of performance patterns are contained in a pack which is a minimum storage unit that can be individually recognized by the portable terminal OS, and the performance pattern assigned to the switch is determined by selecting the pack. Since the pack changing means is provided, a desired performance pattern is selected from the selected pack and pattern instruction data for instructing the performance pattern is arranged to create a pattern sequence. In this case, the contents of the pattern sequence can be changed to another music by changing the pack by the pack changing means without changing the pattern instruction data. Therefore, by simply changing the type of the pack, the existing performance pattern arrangement can be diverted to edit a new music piece, which contributes to the creation of a variety of music pieces and further promotes the motivation of music piece creation.

According to the present invention, when the pattern sequence in which the pattern instruction data for instructing the performance pattern selected by the switch operation is arranged in the reproduction order corresponding to the predetermined timing is created, the pattern sequence is
In accordance with the instruction of the pattern instruction data, the performance patterns recorded in the storage means of the mobile terminal are sequentially developed and converted into music data. Since this music data is event format data that can be played back in common in a plurality of types of information devices including mobile terminals such as mobile phones, it can be used as it is in other information devices that do not store various performance patterns.
Can be used.

Since transfer permission information is added to the music data so that the music data can be transferred to another information device, the music data can be effectively used in another information device. Further, the music data is set such that the non-editable information is added so that the music data cannot be edited, so that the result data obtained by the individual (creating) work by the user can be effectively protected.
