DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game sound program development support device and a sound program development method, and more particularly to a sound program for game music and sound effects (simulated sounds) generated in connection with a game screen. The present invention relates to a game sound program development support device and a sound program development method.

[0002]

2. Description of the Related Art Conventionally, game music and sound effects generated in connection with a game screen provide a synergistic auditory effect to the player in addition to the visual effect of the game screen depending on the content. As a result, an important staging effect in the game has been exhibited, such as being immersed in the game content or scenario, and enhancing the sense of reality. When developing such a game music or sound effect sound program, the score composed by the composer of the game music and sound effect is given to the sound programmer, and the sound programmer views the score and relates to the game screen of the game machine. A sound program has been created or developed by operating a computer keyboard and inputting a program (source code) in a predetermined programming language so as to generate game music according to a musical score at a timing. Therefore, when creating and developing sound programs, in addition to music knowledge,
Programming knowledge was also required, and skill development was required for sound program development. Therefore, the person in charge of game music needs to have both music knowledge and composition and programming skills, or a dedicated person who has programming skills separately from a person with music knowledge and composition skills (composer). A programmer was needed and had to be developed manually. Also, conventionally, if a composer wants to modify game music so that it is suitable for a game screen or a game scenario, it is necessary to have a sound programmer modify the program by explaining the modifications and details of the modification. And it was difficult to develop sound programs quickly and efficiently.

[0003]

2. Description of the Related Art To solve the above problems, a sound program development support system as shown in a functional block diagram of FIG. 6 and a sound program development process chart (flow chart showing work procedures) of FIG. 7 is considered. With reference to FIG. 6, an outline of a sound program development support device (a so-called development tool; hereinafter, abbreviated as "sound development support device") as a background of the present invention will be described. The sound development support device 60 includes a waveform editing unit 61, a waveform converter 6
2. MIDI (Musical Instrument)

6 inclusive. These waveform editing unit 61, MIDI sequence processing unit 63, and sound program generation unit 65 are specifically a personal computer (PC or CP).
U) and software (for example, waveform editing software, MIDI sequence processing software, sound program creation software, etc.) programmed to realize the functions of these units. In addition, the waveform editing unit 61
A waveform data (or sound source) generator 1 is connected. MID
An electronic musical instrument (or an electronic keyboard musical instrument) 3 is connected to the I-sequence processing unit 63 via the MIDI interface 2. The electronic musical instrument 3 has a MIDI data input / output function of a keyboard musical instrument or the like, and is connected to the waveform data generator 1 via the MIDI interface 2. The speaker 4 is connected to the waveform data generator 1. A keyboard 5 is connected to the personal computer, and a display 6 such as a CRT or LCD for displaying the processing or operation state is connected to the personal computer.

[0004] A waveform editing unit 61 selects a desired type of waveform data from a plurality of types of waveform data serving as a sound source generated by the waveform data generation unit 1 based on an operation of the keyboard 5, and outputs the selected waveform data. The waveform data of the necessary period is extracted and the waveform data is temporarily stored. The extracted waveform data (Audio Int
update File Format; "AIF
F) is converted into a format by the waveform data converter 62 and is appropriately compressed at the same time, and is written as waveform data (or sound source data) by the sound program generation unit 65 to a readable / writable memory 66 such as a hard disk. . On the other hand, when the composer (game music staff) operates the electronic musical instrument 3 to play game music, the MIDI data based on the operation of the electronic musical instrument 3 becomes M
The data is input to the MIDI sequence processing unit 63 via the IDI interface 2. MIDI sequence processing unit 6
Numeral 3 decomposes the performance music (game music) into pitch, duration and volume corresponding to each note, and the timbre of the musical instrument of the performance part, and divides the pitch, duration, volume and timbre of the game music. The music data (MIDI data) composed of each data is numerically generated and sequentially generated, and the MIDI data is cumulatively stored. M
The IDI data is subjected to format conversion (for example, conversion to a source code) by the MIDI converter 64 after completion of creation of one piece of music, converted to machine code by the sound program generation unit 65, and then written to the memory 66. The sound program to which the waveform data and the MIDI data after the format conversion stored in the memory 66 and the driver basic program necessary for reproducing them in combination are added is taken out as the sound program file data, and Test board (or cartridge) memory (RAM for debugger)
Or flash memory).

Referring to FIGS. 6 and 7, a procedure of a sound program development process using the sound development support device 60 will be described. In step 71, the composer operates the electronic musical instrument and composes game music using commercially available music sequence software. In step 72, MIDI data of the composed game music is created by the MIDI sequence processing unit 63 and written to the memory included in the MIDI sequence processing unit 63. Step 73
In, it is determined whether or not the composition has been completed, and the operations and operations of steps 71 to 73 are repeated until the music of the game music is completed. When the composer completes the composition, it is determined in step 73 and the process proceeds to step 74. In step 74, the MIDI data and the score data (Standard) of the previously composed game music
MIDI File) is created. In step 75, a waveform (A) serving as a sound source used in game music
IFF) data is created by the waveform editing unit 61 and stored in a memory (not shown) included in the waveform editing unit 61. In step 76, the created MIDI data is subjected to format conversion (for example, conversion to source code) by the MIDI converter 64, and
The FF data is subjected to format conversion and data compression by the waveform data converter 62, and is supplied to the sound program generator 65. The AIFF data is also used as a game sound effect (game sound) as needed. In step 77, MIDI data and AI
The FF data and the like are converted into machine codes by the sound program generation unit 65, and a sound program is created. In step 78, after the sound object file of the sound program is created and the sound object file and the object file of the monitor program are linked, a binary file is created and written to the memory 66 and temporarily stored.
In step 79, the binary file stored in the memory 66 is written into the RAM (or flash memory) of the test board or the test cartridge for debugging, mounted on the game machine, and played by the game machine. .

[0006] In step 80, the composer listens to the music or sound effects generated by the actual game machine and determines whether or not the music or sound effects are reproduced as the image or the sound image when the music was composed, that is, game music and game sound. Check the degree of perfection. If the game music according to the image is not completed, the composer returns to the process of step 71 again to perform the correction work, and repeats the processes or the work of steps 71 to 80. Then, when the game music as the image is completed, in step 81, the music (MIDI or musical score) data and the waveform (tone color) data are determined. After that, the composer outputs the sound program stored in the memory 66 as a sound object file, records the sound program on a floppy disk or the like, and passes it to the main programmer who is developing game software. The main programmer completes the game program by combining the sound object file (or the sound program) with the main program, and transfers the game program to a manufacturing process of a copy for sale (for example, a ROM cartridge).

[0007]

The sound development support device 60 or the sound program development method shown in FIGS. 6 and 7 (hereinafter referred to as "background art") is troublesome when modifying a sound program. There is a problem that it takes time, cannot be quickly corrected, and takes a long time to develop a sound program. Here, the cause of the correction is a large quality difference between the waveform data (sound source data) generated by the waveform generation unit and the waveform data that can be generated by the waveform generation circuit built in the tone generator chip in the game machine. Because of the difference, there may be a case where a gap occurs between the music heard in the composition stage and the music generated using the sound source chip of the game machine, and it is conceivable to change the waveform data and / or the music data (MIDI data). . That is, the waveform data generated by the waveform data generating unit 1 is high-quality sound data of a musical instrument or sound source data of the electronic musical instrument 3 recorded from a microphone.
On the other hand, the sound source data of the game machine uses waveform data that has been subjected to data compression in response to a request for a reduction in capacity in the development of game software. Therefore, the CP of the game machine
The music obtained by U processing the sound program sounds lower-quality music than the music heard at the time of composition, and in some cases, may be significantly different from the music assumed by the composer. In order to solve the problem, it is necessary to change the combination of the waveform data and partially correct the music data. However, if you change the type or combination of the waveform data or modify the song data,
Each time the sound program is also modified, the modified sound program is stored in the flash memory of the test board, EP-
After writing to the ROM or the debugging RAM, the game music must be mounted on the game machine and played back on the game machine for confirmation. Therefore, the procedure for correction and confirmation becomes complicated, and time for correction and the like is required. This is not only troublesome, but also causes a longer development period.

Therefore, a main object of the present invention is to enable a person who has composition ability but no programming ability to develop a sound program for a game, and to efficiently develop a sound program. A game sound program development support device and a sound program development method are provided. Another object of the present invention is to provide a sound program development support device for a game, which can reduce the burden on a person engaged in the development of a sound program, and can concentrate on music composition creation activities rather than on program development when developing a sound program. The purpose is to provide a sound program development method.

Next, the operation of the sound development support apparatus 10 shown in FIG. 1 will be briefly described. The composer selects the waveform data generator 1
When the user wants to compose a music using a sound source which is also used for the user, the user operates the keyboard 5 to select the normal mode. Further, the composer operates the keyboard 5 to select one or more desired waveforms from among various types of waveforms built in the waveform data generating unit 1. When the game music is composed of a plurality of parts (for example, a melody, a bass, a piano, a drum, and an organ), waveform data serving as a sound source for each part is selected. In response to this, the waveform editing unit 11 selects a desired waveform among a plurality of types of waveforms generated by the waveform data generation unit 1 based on the operation of the keyboard 5, and selects necessary waveforms from the selected waveform data. Is extracted, and the waveform data is written into the waveform data storage unit 19a. The waveform data (AIFF data) is subjected to format conversion by the waveform data converter 12 and data compression at the same time, and is provided to the sound program generation unit 15. For example, AIFF data is compressed by being converted into differential PCM data, and differential PCM data is converted into source code. The sound program generation unit 15 converts the waveform data into machine code, reads the driver basic program stored in the storage unit 18a, and converts the converted waveform data into driver basic program data (eg, , The start / stop of the music, the change of the pitch, etc.) are added to the data and written in the storage unit 19c, thereby temporarily storing the data. The storage unit 19 at this time
The storage state of c is shown in FIG. When a composer (game music staff) operates the electronic musical instrument 3 to play game music, game music data is input to the MIDI sequence processing unit 13 via the MIDI interface 2. The MIDI sequence processing unit 13 decomposes the performance music (game music) into pitch, pitch, and volume elements corresponding to musical notes, and musical instrument timbre elements, and generates game music pitch, pitch, volume, and so on.
Music data (MIDI data) composed of tone color data (ie, tone value, tone length, volume, etc. and tone color code) is created, and these MIDI data are stored in the storage unit 19b.
Write to. The MIDI data is supplied to the waveform data generation unit 1 via the MIDI interface 2 and is generated from the speaker 4 as a sound of a pitch, a sound length, and a volume input using the waveform data corresponding to the tone color code. The composer composes music while listening to music generated from the speaker 4. At this time, the MIDI data of the game music that is being composed is cumulatively stored in the storage unit 19b.

On the other hand, if the composer wishes to compose while listening to game music in the same environment as the environment in which the game machine 22 is used,
The user operates the keyboard 5 to select the real-time mode. In response, the switching control unit 17 switches the output (MIDI data) of the MIDI sequence processing unit 13 to a connection mode that can be supplied to the monitoring program supply unit 21 in real time. At the same time, the monitor program generation unit 16 reads the driver basic program and the converted waveform data stored in the storage unit 19c, and stores the driver basic program and the converted waveform data in the storage unit 16 in addition to the driver basic program and the waveform data. A playback program (a playback program for monitoring) is added to the monitoring program, and supplied to the monitor program supply unit 21 to write the playback program, the driver basic program, and the waveform data into the built-in RAM and temporarily store them. The stored data in this state is shown in FIG. In this state, when the composer plays the game music composed by operating the electronic musical instrument 3,
The MIDI data of the game music is sequentially accumulated and stored in the storage unit 19b, and at the same time, is input to the monitoring program supply unit 21 via the MIDI sequence processing unit 13 and the switching control unit 17 in real time and is temporarily stored. Various data stored in the monitor program supply unit 21 is read and processed by the CPU 23.
That is, the CPU 23 generates the composed game music and / or sound effects by processing the MIDI data and the waveform data in combination based on the reproduction program and the driver basic program. This game music and / or sound effect is generated from the speaker 25. Thereby, the composer can compose the music while confirming the identity of the music while listening to the game music and the like generated from the speaker 25, and can compare the sound heard from the speaker 4 with the game machine 22.
It is possible to compose the game music while checking in the same environment as the environment used during game play, and there is also an advantage that it can be immediately corrected if it differs from the image.

By performing the above operations and processes, 1
When composition of all game music to be generated in a plurality of scenes of one game software is completed, MIDI data of all game music is cumulatively stored in the storage unit 19b. Thereafter, the composer operates the keyboard 5 to select an output (readout) mode. In response, the switching control unit 17 outputs the output of the MIDI sequence processing unit 13 to the MID
Switching is performed so as to transfer the data to the I converter 14. Then, the MIDI sequence processing unit 13 sequentially reads out the MIDI data of the game music stored in the storage unit 19b, and outputs the MIDI data to the MIDI converter 14 via the switching control unit 17.
Give to. The MIDI converter 14 sequentially converts MIDI data into a format (for example, converts the data into a source code).
Then, it is given to the sound program generation unit 15. The sound program generation unit 15 outputs the format-converted M
The IDI data is converted into machine code and stored in the storage unit 19c.
Is written to the MIDI data storage area. The storage state of the storage unit 19c in this state is shown in FIG. In this way, the storage unit 19c stores one or more types of waveform data used for generating game music in all scenes of one game, and stores game music or sound effects using the waveform data. MIDI data (music data of a plurality of music pieces) to be generated is accumulated and stored. MI
When the editing work of the DI data is completed, the composer operates the keyboard 5 to instruct the output of the machine code of the sound program relating to the game music stored in the sound program storage unit 19c. In response to this, the edited waveform data and MIDI data and the data to which the driver basic program necessary for reproducing them in combination are added are read out as a sound program file, and are read out as appropriate media (floppy disk, MO or CD-R) and passed from the composer to the main programmer. The main programmer combines the sound program with the main program to complete the game program, and then transfers the duplication process.

FIG. 4 shows a sound program development process (procedure) by the sound development support apparatus according to one embodiment of the present invention.
5 is a flowchart for explaining FIG.

FIG. 5 shows the composition state of the game music (MIDI data creation state) in the sound program development process.
2 shows a display example of a display for explaining the following.

Next, the details of the sound program development process (development procedure) will be described with reference to FIGS. 1 to 5 along the flowchart of FIG. In step 1,
The mode is set. This mode setting is performed, for example, when a composer operates the keyboard 5 (or mouse) when a mode selection screen is displayed on the CRT 6. In step 2, it is determined whether the real-time mode has been selected. When the normal mode (the mode other than the real-time mode) is selected, processing similar to steps 71 to 81 described with reference to FIG. 7 is performed. In other words, the document number

The same processing as the operation in the normal mode shown in FIG. 1 described above is performed. Therefore, detailed description of the normal mode is omitted.

On the other hand, when the real-time mode is selected, in step 3, the composer operates the keyboard to select waveform data to be used for game music and to edit the data as appropriate. This edited waveform data (AIFF
Data) is written to the storage unit 19a and is temporarily stored. In step 4, only the waveform data is subjected to format conversion and data compression by the waveform converter 12 and supplied to the sound program generator 15.
In step 5, the sound program generator 15
Converts the waveform data into machine code, writes the waveform data and the driver basic program into the storage unit 19c,
Store it temporarily. In step 6, the monitor program generation unit 16 sets the sound program (waveform data + driver basic program) stored in the storage unit 19c.
And a monitor program linked (or combined) with the playback program stored in the storage unit 18b,
It is written into the monitor program supply unit 21 and is temporarily stored. In step 7, the composer sets the electronic musical instrument 3
Is operated, the electronic musical instrument 3 generates MIDI data corresponding to the score of the music (game music). The MIDI data is provided to the MIDI sequence processing unit 13 via the MIDI interface 2 and is stored in the storage unit 19 by the MIDI sequence processing unit 13.
At the same time, the data is written into the MIDI data storage area of the monitor program supply unit 21 via the switching control unit 17 in a first-in first-out manner. At this time, the storage unit 19b stores all the game music MIDI data (the pitch, length, and the like of each note of the musical score) input by operating the electronic musical instrument 3.
(Volume, timbre code) are cumulatively stored.
In step 8, based on the MIDI data stored in the memory of the monitor program supply unit 21, the CPU 23 uses the waveform data corresponding to the tone color code to execute the pitch, length, and volume of each note of the musical score played. The game music is generated in real time by generating such sounds. The MIDI data creation processing in steps 7 and 8 is performed for each part such as a melody, a bass, a piano, a drum, and an organ. Note that the game music reproduction process in step 8 may be performed for each part, and then all the parts are combined and processed. In this case, the score of each part and / or the scores of all parts are displayed on the display 6, and a cursor (vertical bar) is displayed at a portion corresponding to the bar or note being played, so that the music is generated. By moving the cursor, the composer can check the score while looking at the score. In step 9, it is determined whether the composition has been completed. This determination is made, for example, by determining whether or not the composer has operated the keyboard 5 to input a command or code indicating “composition completion”. If the composition has not been completed, the process returns to step 7, and the processing or steps of steps 7 to 9 are repeated to compose the game music. When a plurality of songs are composed according to a scene in one game, a file number or the like of the song input by operating the keyboard 5 is added each time one song is created.

When the composition of all the game music to be generated in a plurality of scenes of one game software is completed, it is determined that there is an input indicating that the composition has been completed, and the process proceeds to step 10. In step 10,
A format conversion process of MIDI data (or MIDI data and AIFF data) is performed. In particular,
First, the switching control unit 17 is switched to the MIDI converter 14 side. The MIDI sequence processing unit 13 sequentially reads the MIDI data of the game music stored in the storage unit 19b, and supplies the MIDI data to the MIDI converter 14 via the switching control unit 17. The MIDI converter 14 has the MID
The I data is sequentially converted in format (for example, converted into source code) and provided to the sound program generation unit 15. The sound program generator 15 converts the MIDI data into a machine code and writes the machine code into the MIDI data storage area of the storage 19c. Thus, the storage unit 19
c is the format-converted and data-compressed 1
One or more types of waveform data used for generating game music in all scenes in one game, and MIDI data (multiple song data) for generating game music or sound effects using the waveform data ) Is accumulated and stored. When the MIDI data conversion / editing operation is completed, a sound program creation process is performed in step 11. Specifically, the composer operates the keyboard 5 to instruct the output of the machine code of the sound program related to the game music stored in the storage unit 19c. Accordingly, the edited waveform data and M
The IDI data and the data to which the driver basic program necessary for reproducing them in combination are added are read out as a sound program file and written to an appropriate medium (floppy disk, MO, CD-R, or the like). Is passed from the composer to the main programmer.

In this manner, the composer can compose music while listening to game music generated by the same environment as the game machine 22 actually used, and can compose music or game music that matches the image. Yes, you can easily create sound programs in parallel.

In the above-described embodiment of FIG. 1, only the waveform data is converted into a format, compressed and stored in the storage unit 19c, and the MIDI data is monitored in real time in accordance with the performance input. Although the case of supplying the program to the application program supply unit 21 has been described, various modifications may be considered. For example, the format conversion processing of the waveform data may be performed later together with the MIDI data. In that case, a circuit similar to the switching control unit 17 is provided between the waveform editing processing unit 11 and the waveform converter 12, and the waveform data is directly supplied to the monitoring program supply unit 21. Instead, the driver basic program and the monitor program are supplied to the monitor program supply unit 21 in advance.

In the embodiment of FIG. 4 described above, if it is desired to correct the waveform data while MIDI data of game music is being input (before completion of composition), it is determined in step 9 that the composition has not been completed. A step of determining whether or not data correction is necessary may be added, and the process may return to step 3 after determining that the waveform data should be corrected. If it is necessary to correct not only the setting of the waveform data but also the waveform of the envelope signal, step 4
An operation for setting an envelope value may be added between step 5 and step 5. In this case, more preferably, after it is determined that it is not necessary to correct the waveform data, it is determined whether it is necessary to change the setting of the envelope values (each of the attack time, the decay time, the sustain level, and the release time). A step may be added, and when it is determined that the envelope value should be changed, the process may return to the operation step of setting the envelope value. As described above, the sound source portion of the game machine is made to sound as a MIDI receiving sound source, so that the completeness of the waveform data of the game sound to be produced and the completeness of the waveform envelope can be determined by the MIDI data such as when a single sound or plural sounds are produced. Setting has the advantage that it can be confirmed by sound generation simulation in real time.

Further, the technical idea of the present invention can be used not only for a game music developer but also as a tool for a user to create his own game music. In this case, the parts of the waveform editing unit 11 to the switching control unit 17 and the monitoring program supply unit 21 are integrated into a one-chip IC, and the storage units 18a and 18b are ROMs and the storage unit 1
By reducing the capacity of the flash memory 9a to 19c by using a flash memory or a RAM and storing them in a single cartridge, the price is reduced and sold as game music development software. As a result, the user
If you have an electronic musical instrument with an IDI function, you can easily create game music and enjoy playing games while playing your own composed music as BGM.
