In addition, music data may be stored in the ROM 2 in advance. The sound middleware 1b is a function executed by the CPU 1, reads the music data 3b from the RAM 3 under the instruction of the SMAF Script player 1a, and plays / reads the read data on the read data. Playback control such as stop / pause / rewind is performed. The sound source 10 receives an event string having time information supplied from the sound middleware 1b, and when a specified time is reached, the sound source 10 analyzes the event, generates a sound signal, and outputs it to the speaker 11. As the event, a pronunciation event, a tone tone change event, a volume change event, a pitch change event, and the like are used, and the sound source 10 performs an operation according to these events. This operation corresponds to normal MIDI data processing. The time management may be performed by the sound middleware 1b.

FIG. 4 is a flowchart for explaining the operation of the functional block diagram shown in FIG. 3.

When the music data editing and reproduction processing is started, the sound middleware 1b reads the existing music data 3b, prepares a list, and displays it on the display unit 5. FIG. The list shows a list of pieces of music registered in the piece of music data 3b and section information defined for each piece of music (step Sa1). The user creates a SMAF Script so that the desired medley music is realized according to the SMAF Script creation application executed by the CPU 1 with reference to the list (step Sa2). The created SMAF Script is read by the SMAF Script player 1a (step Sa3).

The SMAF Script player 1a registers the music data designated by the SMAF Script to the sound middleware 1b (step Sa4). The SMAF Script player 1a analyzes the SMAF Script, and issues a playback instruction to the sound middleware 1b according to the description sequence of the SMAF Script based on the designated music data (step Sa5). For example, in the case of the SMAF Script shown in FIG. 2, first, reproduction of the climax SB portion of the file 1 is instructed, and next, the portion of the A melody AM and the climax SB portion of the file 2 is indicated. Twice playback is instructed, and then, sequential playback of the climax SB, electric pole IN, climax SB, and ending (EN) portion of file 1 is instructed. The sound middleware 1b transmits an event string having time information to the sound source 10, and when the sound source 10 reaches the designated time, the sound source 10 interprets the event and performs actual pronunciation (step Sa6). Steps Sa5 and Sa6 described above are repeated until the end of the SMAF Script (step Sa7). In addition, the SMAF Script created by the user can be stored in the RAM 3.

Next, a second embodiment of the present invention will be described with reference to FIGS. 5 and 6. The hardware configuration of the second embodiment is the same as that shown in FIG. 1, and the method of describing the SMAF Script is also the same as that shown in FIG.

As an event, a pronunciation event, a timbre change event, a volume change event, a pitch change event, etc. can be used, and the sound source 10 performs an operation according to these events. This operation corresponds to normal MIDI data processing. The time management may be performed by the sound middleware 1d.

FIG. 6 is a flowchart for explaining the operation of the functional block diagram shown in FIG. 5.

When the music data editing and reproducing process is started, the SMAF Script player 1c reads the music data 3b from the RAM 3, creates a list, and displays it on the display unit 5. The list shows music list and section information defined for each piece of music (step Sb1). The user creates a SMAF Script 3a so as to realize the desired medley music in accordance with the SMAF Script creation application executed by the CPU 1 with reference to the list (step Sb2). The created SMAF Script is read by the SMAF Script player 1c (step Sb3). The SMAF Script player 1c analyzes the SMAF Script and generates music data corresponding to the medley music according to the description of the SMAF Script based on the designated music data 3b (step Sb4).

Next, the SMAF Script player 1c stores the generated music data in the sound middleware 1d (step Sb5). Next, the SMAF Script player 1c issues a playback instruction to the sound middleware 1d (step Sb6). The sound middleware 1d receives a playback instruction and transmits an event string having time information to the sound source 10. The sound source 10 analyzes an event when it reaches the predetermined time, and performs actual pronunciation (step Sb7). The generated music data and SMAF Script can be stored in the RAM 3 like the existing music data.

According to the first and second embodiments of the present invention described above, the following effects can be obtained.

(1) The variation of the method of reproducing one piece of music can be easily increased.

(2) By editing the text file, it is possible to easily change the order of the playback sections in the music.

(3) Using a plurality of pieces of music data as the material, the user can organize the music data of the preference accordingly. For example, a new incoming melody can be created based on the incoming melody already stored in the cellular phone.

(4) The function of the present invention can be applied as an application of a mobile phone, whereby desired music data according to various situations can be constructed based on a small number of music data. As a result, the memory usage efficiency can be improved in a small portable information terminal such as a cellular phone.

(5) Based on the existing music data registered and maintained via the network, the user can organize music data of preferences only by describing the text file.

The present invention need not be limited to the above embodiments, and various designs can be changed and applied. For example, the music data editing / reproducing apparatus according to each embodiment can be applied as follows.

(a) Application to incoming melody of mobile phone. In other words, the user can create a piece of music by using the music data for the incoming melody already downloaded by the user and stored in the RAM 3 as a material. In this case, an application such as continuous playback of a climax portion of an incoming melody already registered is possible, and other applications can be provided for various uses.

(b) The user can create a piece of music by using the existing piece of music data registered and maintained via the network as the material. The technique can also be applied not only to mobile phones but also to personal computers connected to a network.

(c) Register the SMAF Script as an incoming melody. Accordingly, a new incoming melody can be defined based on the existing music data downloaded to the mobile phone.

(d) Apply SMAF Script to games written in Java. As a result, the same piece of music data can be used for various game scenes, thereby improving memory usage efficiency.

(e) The SMAF Script is used as a replay trigger and indicates values such as time and battery level. For example, SMAF Script to be played back at a predetermined time is set in advance. It is also possible to set to play a specific SMAF Script when the battery level reaches a predetermined value. Accordingly, by using only one piece of music data, the playback section can be changed in accordance with time, or the playback section can be changed in accordance with the remaining battery capacity, thereby providing a new service for the user.

In the above embodiment, the SMAF Script is used to create a medley piece of music, but the playing part of each musical instrument included in the piece of music may be designated using the SMAF Script. For example, File1.mmf specifies music data according to a first drum part that stores only a drum part consisting of a predetermined drum playing pattern, and File2.mmf includes parts of a musical instrument other than the drum part (melody part). Music data according to the second drum part representing a drum playing pattern different from the first drum part, and File3.mmf specifies music data according to the second drum part. Specifies a playback section such as SB and EN. Here, a technique of simultaneously playing back arbitrary portions of each file is given to the SMAF Script. For example, the following technique may be performed.

<PLAY> 00000 File2.mmf IN & File1.mmf IN00001 File2.mmf AM & File3.mmf AM

According to the above technique, when the IN portion of File2.mmf is played back, the IN portion of File1.mmf is played back simultaneously, and when the IN portion of File2.mmf is finished playing, the AM portion of File2.mmf is continuously played. At the same time, the AM section of File3.mmf is played. That is, the playback can be performed by freely combining the desired playback sections of each performance part of the piece of music. In such a reproduction method, for example, by changing the stored contents of File1.mmf, the variation of the music can also be changed at the same time. In addition, in the above description, the symbol "&" executes the description contents after the symbol during execution of the description contents before the symbol, that is, the reproduction of the next piece of music data during the reproduction of the first piece of music data. I mean.

Furthermore, a unique identifier (ID) for specifying the music data can be included in the music data. That is, the music data file may be designated by SMAF Script using the ID.

Further, the present invention has a remarkable effect in the generation of the incoming melody in the mobile phone, in particular in the operation of generating the desired music by the user.

According to the present invention, it is possible to provide a music data editing and reproducing apparatus capable of designating an arbitrary portion of a piece of music desired by a user and generating a medley piece of music, and to provide a portable information terminal to which the music data editing and reproducing apparatus is applied.
