[Score data use processing]
In the musical score data utilization system according to one embodiment of the present invention, as described above, a plurality of n environment setting data (registration data) Dr1 to Drn to which the setting accompanying information Dra is assigned are stored in the storage means 3 and 4, respectively. ing. When displaying a score and performing along with a musical piece of the score, the score data Dm representing the score to be displayed is acquired according to the score data use processing program, and the score-accompanying information Dma is extracted from the acquired score data Dm. The extracted score accompanying information Dma is compared with the setting accompanying information Dra of each environment setting data Dr1 to Drn. By this comparison, the environment setting data Dr to which the setting accompanying information Dra having a high degree of coincidence with the score accompanying information Dma is selected, and the performance environment of the tone signal generating unit 9-10 is set based on the selected environment setting data Dr. To do. That is, the musical tone signal generator 9-10 sets a performance environment that matches the musical score displayed based on the musical score data Dm, and based on the performance information that is input in accordance with the musical performance of the musical score, A musical tone signal is generated under. Here, with respect to the environment setting data Dr set in the musical sound signal generation unit 9-10, in the first mode, the data to which the setting accompanying information Dra indicating the highest matching degree with the score accompanying information Dma is automatically added. In the second mode, a plurality of environment setting data candidates to which setting accompanying information Dra indicating a high degree of coincidence is given are presented, and one of the candidates is selected according to a user operation.

  FIG. 3 is a flowchart showing the score data utilization processing according to one embodiment of the present invention. This processing flow starts when the electronic music apparatus is turned on. The CPU 1 performs initial setting in the first step S1, for example, by default, sets the operation mode to the score data use mode, and sets the registration setting mode to the first. In addition to setting the mode, the menu screen of the musical score data use mode is displayed in the menu screen area of the screen display section of the touch panel 17. After the initial setting, it is checked whether or not the performance operator 15, the setting operator 16 or the operation unit of the touch panel 17 has been operated. First, in step S2, an instruction from the user for the score data selection start item in the menu screen It is determined whether or not an operation has been performed.

  If it is determined that an operation for starting musical score data selection has been performed (S2 = YES), the process proceeds to step S3, and the musical score data item information that can be used (acquired) by displaying the musical score data selection screen on the screen display unit. When the user presents an item instruction operation, the musical score data Dm designated corresponding to this operation is acquired from the storage means 3 or 4 or the server device (server computer) 70 and stored in the musical score data storage area of the RAM 2. To do. In the next step S4, a score (music score) is displayed on the screen display unit based on the score information of the score information chunk Dms of the score data Dm acquired in the RAM 2.

  When it is determined that the musical score data selection start operation is not performed (S2 = NO), or after the musical score display process of step S4 is performed, in step S5, the musical score data Dm is acquired and the registration in the menu screen is performed. It is determined whether or not an instruction operation by the user has been performed on the setting start item. When the musical score data Dm is acquired and the registration setting start operation is performed (S5 = YES), the process proceeds to step S6. In step S6, registration setting processing (see FIGS. 4 and 5) is performed in accordance with the currently set registration setting mode, and the plurality of registration data Dr1 to Drn prepared in the electronic music apparatus are acquired in step S3. The optimum registration data Dr suitable for the musical content of the musical score data Dm is selected, and the performance environment of the tone signal generator 9-10 is set according to the selected optimum registration data Dr.

  If the registration setting start operation is not performed or the musical score data Dm is not acquired even though the registration setting start operation is performed (S5 = NO), or after performing the registration setting process in step S6, the process proceeds to step S7. In step S7, if the performance is currently possible and the user performs a performance operation (15), performance information corresponding to the user's performance operation is sent to the musical sound signal generator 9-10, and a musical sound signal is generated based on the performance information. Is instructed to the tone signal generator 9-10. If the performance is not possible or there is no performance operation, the process goes through step S7.

  Next, the process proceeds to step S8. If there is another user operation, the corresponding "other process" is performed according to the user operation. If there is no other valid user operation, step S8 is passed. Then, after step S8, the process returns to step S2, and the above-described processing operations of steps S2 to S8 are repeated until the apparatus is turned off.

  In the other processing in step S8, for example, after the musical score data Dm is acquired (S3) and the registration setting processing (S6) is performed, if there is an instruction operation on the performance start item in the menu screen, the performance is enabled. At the same time, the progress control of the score display based on the score data Dm is started. In this progress control, the musical score display progresses with time, and for example, the current performance position on the musical score is moved, the page is switched, or scrolling is performed. In addition, if there is an instruction operation for a registration setting mode change item on the menu screen in the score data use mode, the registration setting mode setting is changed from the first mode to the second mode or from the second mode to the first mode. . If there is an instruction operation for the operation mode change item, the setting of the operation mode is changed from the score data use mode to the normal mode or from the normal mode to the score data use mode. In the normal mode, music score display, registration setting, performance, etc. can always be performed independently.

<Registration setting process in the first mode>
When the registration setting mode is set to the first mode, the registration setting process executed in step S6 of the score data utilization process (FIG. 3) is referred to as “registration setting process 1”. FIG. 4 is a flowchart showing the registration setting process 1. First, in the first step A1, score accompanying information is acquired from the score accompanying information chunk Dma of the score data Dm being displayed, and in the next step A2, environment setting instruction information and score indicating the data for the optimum resist data Dr. An environment setting instruction register (referred to as an optimal instruction register) provided on the RAM 2 is initialized in order to maintain a degree of coincidence (described later) with the accompanying information Dma.

  Next, in step A3, the registration data Dr1 to Drn stored in the storage means 3 and 4 are sequentially selected one by one, and in step A4, the setting incidental information is acquired from the setting incidental information chunk Dra of the selected registration data. To do. In the next step A5, the score accompanying information Dma obtained in step A1 is compared with the set accompanying information Dra obtained in step A4, and the degree of coincidence (match degree) of the information of each item between the accompanying information Dma and Dra is determined. Ask. The degree of coincidence is represented, for example, by the ratio of items that match the items of the musical score accompanying information Dma among all the items of the setting accompanying information Dra. Of course, it is not limited to this as long as it represents the degree of matching between the accompanying information Dma and Dra.

  Further, in the next step A6, when the degree of coincidence obtained in step A5 is higher than the highest degree of coincidence obtained so far (stored in the optimum instruction register), the optimum instruction register is updated, and this musical score is attached. The environment setting instruction information indicating the registration data to which the information Dma is added and the degree of coincidence (new maximum degree of coincidence) obtained in step A5 are held in the optimum instruction register. If the degree of coincidence obtained in step A5 is lower than the highest degree of coincidence so far, step A6 is passed. When the process proceeds from step A2 to step A3, the first registration data Dr1 [FIG. 2 (2): “registration data 1”] is selected, and the matching degree C1 obtained in step A5 is the highest matching degree. In step A6, the environment setting instruction information indicating the first registration data Dr1 and the matching degree C1 are stored in the optimum instruction register.

  After updating the environment setting instruction information in step A6 or after passing through step A6, it is determined in step A7 whether or not all the resist data Dr1 to Drn in the storage means 3 and 4 have been processed. . If it is determined that all the resist data Dr1 to Drn are not processed (A7 = NO), the process returns to step A3, and the next resist data is selected and the above-described processes of steps A4 to A7 are performed. For example, when returning from step A7 to step A3 for the first time, the second registration data Dr2 [FIG. 2 (2): “registration data 2”] is selected, and the degree of coincidence C2 obtained in step A5 is the previous value. Only when the degree of coincidence is higher than the degree of coincidence C1 of the first resist data Dr1, the optimum instruction register is updated in step A6 with the environment setting instruction information indicating the second resist data Dr2 and the degree of coincidence C2.

  While all the resist data Dr1 to Drn are not processed (A7 = NO), the processing of the above steps A3 to A7 is repeated. When all the resist data Dr1 to Drn are processed (A7 = YES), the process proceeds to step A8. In step A8, the optimum registration data Dr indicated by the environment setting instruction information held in the optimum instruction register is applied to tone generation, and the performance environment of the tone signal generation unit 9-10 is set according to the setting parameter of the setting parameter chunk Drp. Set. Then, the registration setting process 1 is terminated, and the process returns to step S7 of the musical score data utilization process.

<Second mode registration setting process>
When the registration setting mode is set to the second mode, the registration setting process executed in step S6 of the score data utilization process (FIG. 3) is referred to as “registration setting process 2”. FIG. 5 is a flowchart showing the registration setting process 2. In the first step B1, score accompanying information is acquired from the score accompanying information chunk Dma of the score data Dm being displayed, and in the next next step B2, a plurality of m (m values are arbitrarily set to indicate appropriate resist data Dr. Environment setting instruction information provided on the RAM 2 for ranking the environment setting instruction information according to the degree of coincidence with the musical score accompanying information Dma and holding it in a list format is possible. Initialize a register (rank list register or simply rank list).

  In the next steps B3 to B5, as in the resist setting process 1, the resist data Dr1 to Drn stored in the storage means 3 and 4 are sequentially selected one by one (B3), and the setting associated information of the selected resist data is selected. The setting accompanying information is acquired from the chunk Dra (B4), and the acquired score accompanying information Dma <B1> and the setting accompanying information Dra <B4> are compared with each other, and the degree of coincidence of the information of each item between the accompanying information Dma and Dra (Match) is obtained (B5).

  Next, in step B6, when the coincidence obtained in step B5 is higher than any of the high rank coincidences held in the rank list register, the rank list register is updated, and this score accompanying information Dma is added. The environment setting instruction information indicating the registered resist data and the coincidence degree (new high rank coincidence degree) obtained in step B5 are held in the rank list register. If the coincidence obtained in step B5 is lower than the previous high-order coincidence, step B6 is passed. When the process proceeds from step B2 to step B3, the first resist data Dr1 is selected, the coincidence degree C1 obtained in step B5 is set to the high rank coincidence, and the environment indicating the first resist data Dr1 in step B6. The setting instruction information and the degree of coincidence obtained in step B5 are stored in the rank list register.

  After updating the environment setting instruction information in step B6 or after passing through step B6, it is determined in step B7 whether or not all the resist data Dr1 to Drn in the storage means 3 and 4 have been processed. . If it is determined that all the resist data Dr1 to Drn have not been processed (B7 = NO), the process returns to step B3, and the next resist data is selected and the processes of steps B4 to B7 described above are performed. When returning from step B7 to step B3 for the first time and returning from step B7 to step B3 for the second time, the second and third resist data Dr2 and Dr3 are selected, respectively. The environment setting instruction information indicating the data Dr2 and Dr3 and the matching degrees C2 and C3 obtained in step B5 are added to the rank list register as the high ranking matching degrees. Therefore, when returning from step B7 to step B3 after the 3 (m) th time, the degree of coincidence with the score-accompanying information Dma of the newly selected resist data is the high rank coincidence held in the rank list register. When it is higher than any of the above, the information regarding the registration data of the lowest matching degree in the rank list register is deleted from the rank list register.

  While all the resist data Dr1 to Drn are not processed (B7 = NO), the above-described processing of Steps B3 to B7 is repeated. When all the resist data Dr1 to Drn are processed (B7 = YES), the process proceeds to Step B8. In step B8, based on the contents of the rank list register, guide information of the top three (m) resist data suitable for the musical contents of the score data Dm is displayed as a list of selectable resist data candidates. The user waits for a registration data selection operation by the user. The guidance information is preferably displayed in descending order of the degree of coincidence with the musical score accompanying information Dma, and in addition to the name of the registration data (corresponding to “a. Song name”), the main items of the setting accompanying information Dra ( For example, it is preferable to include information such as genre, time signature, organization, melody instrument) and score coincidence information Dma. In the next step B9, the user's registration data selection setting operation on the registration list display screen on the touch panel 17 is detected, and in the subsequent step B10, the registration data Dr corresponding to the user operation is selected as the optimum registration data to be set. Then, the selected optimum registration data Dr is applied to tone generation, and the performance environment of the tone signal generation unit 9-10 is set according to the setting parameter of the setting parameter chunk Drp. Then, the registration setting process 2 is terminated, and the process returns to step S7 of the musical score data utilization process.
