Description

  The present invention relates to a technique for generating performance control data, and more specifically to a technique for generating other performance control data from one performance control data.

  In recent years, mobile terminal devices such as mobile phones having a function of performing automatic performance based on performance control data have appeared. Furthermore, performance control data stored in a content server or the like is widely downloaded to a mobile terminal device or the like via a wireless communication network or the like.

  By the way, as a format of performance control data, SMF (Standard MIDI File) has been widely used. However, particularly when performance control data is downloaded to the mobile terminal device via the wireless communication network, the data storage capacity of the mobile terminal device and the data communication capacity of the wireless communication network are limited. Is desired to be reduced. Therefore, performance control data in a format different from SMF, such as SMAF (Synthetic Music Mobile Application Format), has appeared as performance control data capable of expressing similar performance contents with a data size smaller than SMF. .

As described above, since a plurality of formats can be used as the format of performance control data, it is convenient to have a converter that automatically converts between different formats. For example, an application for causing a general-purpose computer to perform conversion processing from performance control data in SMF format (hereinafter referred to as “SMF data”) to performance control data in SMAF format (hereinafter referred to as “SMAF data”). SSC MA3 (SMF to SMAF Converter for MA3) and the like are disclosed (for example, see Non-Patent Document 1).

[2. Operation]
Hereinafter, an operation and operation of the performance control data generation device 11 when the creator uses the performance control data generation device 11 to convert SMF data and generate SMAF data will be described. The creator creates SMF data in advance and stores the created performance control data in the storage unit 104 of the performance control data generation device 11 as an SMF file. The SMF data includes at least sound generation data for instructing sound generation and tone color designation data for designating the tone color of the sound. Here, the timbre designation data can include any data related to the timbre such as timbre number, volume, tone strength, sound effect, etc., but in the following, as an example, the timbre designation data includes the timbre number and the depth of modulation. Data. Note that the timbre number is a number from 1 to 128, and according to GM, for example, 1 indicates a grand piano.

  First, the creator activates a converter application in the performance control data generation device 11. When the converter application is activated, the configuration of the performance control data generation device 11 illustrated in FIG. 2 realizes the functional configuration illustrated in FIG. FIG. 5 is a diagram illustrating a screen displayed on the display unit 106 when the converter application is executed. The converter application screen includes an SMF file designation section 301 for the creator to select an SMF file to be converted, and a pre-conversion tone display section 302 for displaying the contents of the tone selection data included in the SMF data before conversion. The converted tone display section 303 displays the contents of the tone specification data included in the converted SMAF data, the tone change instruction section 304 for the creator to change the tone specification data included in the SMAF data, and the creator sets the SMAF. Audition button 305 for instructing automatic performance by data, SMAF file storage section 306 for the creator to instruct to save SMAF data, and SMAF file for instructing the creator to transmit the SMAF file stored It includes a transmit section 307.

  FIG. 6 is a flowchart of processing executed by the performance control data generation device 11 in response to an operation performed by the creator on the screen shown in FIG. First, the creator selects the file name of the SMF file stored in the SMF file storage unit 201 in the SMF file specification section 301 and clicks the “Open” button. In response to the click operation, the SMF file specification data acquisition unit 202 acquires the file name of the SMF file selected by the creator as SMF file specification data, and sends the acquired SMF file specification data to the tone color specification data extraction unit 203. .

  The timbre designation data extraction unit 203 reads the SMF file having the file name included in the received SMF file designation data from the SMF file storage unit 201 (step S401), extracts the timbre designation data contained in the read SMF file, The result is displayed on the pre-conversion tone display section 302 (step S402). At that time, the timbre name corresponding to the timbre number included in the extracted timbre designation data is also displayed.

  Subsequently, the creator selects a suitable one from the options displayed in “sound source LSI” of the timbre change instruction section 304, and then clicks a “reflect” button shown on the right side. In response to the click operation, the condition data supply unit 204 acquires data indicating the option selected by the creator as the condition data, and supplies the acquired condition data to the alternative timbre designation data generation unit 205 (step S403). In the following description, the condition data supply unit 204 always acquires the condition data from the operation unit 105 according to the operation of the creator. However, the condition data supply unit 204 is not operated by the creator, for example. In some cases, the condition data stored in the storage unit 104 as an initial value may be acquired.

  In the “sound source LSI” of the timbre change instruction section 304, the name of the sound source LSI provided in the mobile terminal 13 where SMAF data is finally used, for example, “sound source LSI-1”, “sound source LSI-2”, etc. Is displayed. The conversion rule data storage unit 206 stores conversion rule data indicating rules for converting SMF data into SMAF data in accordance with each of the sound source LSIs as a type of corresponding data indicating the correspondence between timbres. . FIG. 7 is a diagram illustrating the contents of the conversion rule data. As shown in FIG. 7, the conversion rule data designates according to which rule the data of the item indicated by the conversion item is converted according to each of the sound source LSIs.

  For example, when the creator selects “sound source LSI-1” in “sound source LSI”, the alternative tone color designation data generation unit 205 receives condition data indicating “sound source LSI-1”. In that case, the alternative tone color designation data generation unit 205 reads the conversion rule data corresponding to “sound source LSI-1” from the conversion rule data storage unit 206, and displays the pre-conversion tone color according to the conversion rule indicated by the read conversion rule data. The timbre set name and the timbre name corresponding to the timbre number included in the timbre designation data displayed in the section 302 are displayed in the converted timbre display section 303. Similarly, the alternative timbre designation data generation unit 205 follows a conversion rule indicated in the read conversion rule data, and a value corresponding to the modulation value included in the timbre designation data displayed in the pre-conversion timbre display section 302, In this case, “On” or “Off” is displayed in the converted tone display section 303 (step S404). It is assumed that the creator selects “sound source LSI-1” in “sound source LSI” prior to the operation described below.

  The tone color change instruction section 304 includes “tone color set”, “template”, and “random” in addition to “sound source LSI”. In the “tone set”, names of a plurality of tone sets included in the tone generator LSI selected by the creator in “sound source LSI”, for example, “standard set”, “cyber system set”, and the like are displayed as options. Note that the names of these timbre sets are acquired from the conversion rule data (see FIG. 7).

  For example, when the creator selects “Cyber system set” in “Tone color set”, the alternative sound color designation data generation unit 205 receives condition data indicating “Cyber system set”. In that case, the alternative tone color designation data generation unit 205 changes all the tone color set names of the alternative tone color designation data displayed in the converted tone color display section 303 to “cyber system set”, and uses the alternative tone color designation data after the change. The display of the converted timbre display section 303 is updated (step S404). In this case, the list of emulation timbre groups shown in FIG. 3 serves as correspondence data indicating the correspondence between the timbre before conversion and the timbre after conversion.

  In the “template” of the timbre change instruction section 304, the name of a template of alternative timbre designation data prepared in advance according to the sound source LSI selected by the creator in “sound source LSI”, for example, “quiet classic”, “ “Light Eurobeat” is displayed as an option. The template data storage unit 207 stores a template of standard alternative tone color designation data corresponding to each music genre as template data in accordance with each tone generator LSI. Similar to the conversion rule data, this template data is a type of correspondence data indicating the correspondence between the timbre before conversion and the timbre after conversion. FIG. 8 is a diagram illustrating the contents of the template data. As shown in FIG. 8, the template data corresponds to each tone generator LSI, and any tone color when the tone number included in the SMF data is given for the music genre specified by the template number and the template name. It specifies whether to use the timbre indicated by the combination of the set name and the timbre name in the converted SMAF data. Some sound source LSIs can add changes to the timbre in accordance with data relating to acoustic effects such as “modulation”. In that case, the template data specifies what value data should be added to the converted SMAF data in accordance with the tone color number included in the SMF data.

  For example, when the creator selects “light euro beat” in “template”, the alternative tone color designation data generation unit 205 receives condition data indicating “light euro beat”. In this case, the alternative tone color designation data generation unit 205 reads the template data corresponding to “sound source LSI-1” from the template data storage unit 207, and the template name is “light euro beat” from the read template data. Select some data. Subsequently, the alternative timbre designation data generation unit 205 generates alternative timbre designation data according to the timbre number displayed in the pre-conversion timbre display section 302 according to the selected data, and then displays the converted timbre with the generated alternative timbre designation data. The display of section 303 is updated (step S404).

  In “random” in the timbre change instruction section 304, “high similarity”, “medium similarity”, and “low similarity” are displayed as options. The creator causes the performance control data generation device 11 to generate a combination of timbres that are arbitrarily selected within a similar range between timbres indicated by the selected option by selecting one of the options in “random”. Can do. The timbre similarity data storage unit 208 stores timbre similarity data that is data obtained by classifying other timbres according to the degree of similarity with respect to each timbre specified by the timbre number. FIG. 9 is a diagram illustrating the contents of the timbre similarity data. As shown in FIG. 9, in the timbre similarity data, for each timbre number, a timbre name indicating a timbre with a high similarity is “high similarity” and a timbre name indicating a timbre with a medium similarity Are classified as “low similarity”, and timbre names indicating timbres with low similarity are classified as “low similarity”.

  For example, when the creator selects “medium degree of similarity” in “random”, the alternative tone color designation data generation unit 205 receives condition data indicating “medium degree of similarity”. In that case, the alternative timbre designation data generation unit 205 first reads timbre similarity data from the timbre similarity data storage unit 208. Subsequently, for each of the timbre numbers shown in the pre-conversion timbre display section 302, the alternative timbre designation data generation unit 205 selects data having the same timbre number from the read timbre similarity data, and further selects Any one of the timbre names included in the “medium degree of similarity” of the data is selected. The alternative timbre designation data generation unit 205 changes the timbre name of the alternative timbre designation data displayed in the post-conversion timbre display section 303 with the timbre name thus selected. The alternative timbre designation data generation unit 205 updates the display of the post-conversion timbre display section 303 with the alternative timbre designation data with such changes (step S404).

  As described above, the creator can easily select alternative tone color designation data displayed in the converted tone color display section 303 by selecting a suitable one from the options shown in each item included in the tone color change instruction section 304. Can be changed. At that time, the creator checks a “fixed” check box included in the post-conversion timbre display section 303 with respect to an arbitrary timbre, thereby changing a part of the alternative timbre designation data shown in the post-conversion timbre display section 303. You can also specify that there is no. That is, the substitute tone color designation data generation unit 205 does not update the substitute tone color designation data for the tone color for which the “fixed” check box is checked when performing the process of step S404 described above.

  Further, the creator displays alternatives for each of the timbre set name, timbre name, modulation, etc. displayed in the converted timbre display section 303, and selects a suitable one from the displayed options. The contents of the alternative timbre designation data automatically generated by the timbre designation data generation unit 205 can be individually corrected. In that case, the condition data supply unit 204 supplies condition data corresponding to the input operation of the creator to the alternative tone color designation data generation unit 205, and the alternative tone color designation data generation unit 205 responds to the condition data with the alternative tone color designation data. Update.

  When the creator determines the alternative tone color designation data by the operation as described above, the creator clicks the audition button 305. In response to the click operation, the performance instruction data acquisition unit 209 acquires performance instruction data indicating an instruction for automatic performance, and sends the acquired performance instruction data to the SMAF data generation unit 210.

  When the SMAF data generation unit 210 receives the performance instruction data, the SMAF data generation unit 210 converts the SMF data included in the SMF file previously selected by the creator into the SMAF according to the alternative tone specification data displayed in the converted tone display section 303 at that time. The data is converted into data, and the SMAF data generated by the conversion is temporarily stored in the SMAF data temporary storage unit 211 (step S405). Specifically, when the alternative timbre designation data shown in the converted timbre display section 303 of FIG. 5 is followed, for example, the portion of the SMF data for which the timbre is designated by the timbre number “74” is used as the tone generator LSI. Using the timbre specified by the timbre set name “Cyber system set” and the timbre name “flute” included in -1, timbre designation data for instructing to perform with modulation added is generated, and is stored in the SMF data. After being combined with the included pronunciation data, new performance control data is generated according to the SMAF data format.

  When the SMAF data is stored in the SMAF data temporary storage unit 211, the automatic performance unit 212 performs an automatic performance according to the SMAF data (step S406). At that time, the automatic performance unit 212 performs automatic performance using the timbre included in the emulation timbre group corresponding to the sound source LSI previously selected in the “sound source LSI” of the timbre change instruction section 304 by the creator, and at the same time, The performance sound is subjected to filter processing or the like for reproducing the acoustic characteristics of general mobile terminal amplifiers and speakers. As a result, the creator can audition almost the same performance as when an automatic performance is performed on a mobile phone or the like equipped with the selected tone generator LSI.

  When the creator likes the performance he / she auditioned, after inputting an appropriate file name in the “SMAF file name” of the SMAF file storage section 306, the creator clicks the “save” button (step S407: Yes). In response to the click operation, the save instruction data acquisition unit 213 acquires the file name input by the creator as save instruction data, and sends the acquired save instruction data to the SMAF file generation unit 214. When receiving the save instruction data, the SMAF file generation unit 214 receives the corresponding timbre data, that is, parameter data or waveform for each of the timbre set name and timbre name included in the SMAF data stored in the SMAF data temporary storage unit 211. Data is acquired from the sound source system 108, and the acquired timbre data is added to the SMAF data as part of the alternative timbre designation data. Then, the SMAF file generation unit 214 generates a SMAF file by associating the file name indicated by the save instruction data with the SMAF data to which the timbre data is added, and stores the generated SMAF file in the SMAF file storage unit 215. (Step S408). Note that the type of timbre data such as parameter data and waveform data becomes the type of timbre data corresponding to the selected sound source LSI by selecting “sound source LSI” in the timbre change instruction section 304. For example, if the selected sound source LSI is an FM sound source, FM calculation parameters are added to the SMAF data as timbre data.

  Incidentally, the creator can also click the “additional save” button when the file name of the SMAF file already stored in the SMAF file storage unit 215 is input to “SMAF file name” of the SMAF file storage section 306. . In that case, the SMAF file generation unit 214 generates the SMAF file including the SMAF data included in the already stored SMAF file as the data of Part 1 and the SMAF data to be newly saved as the data of Part 2.
