摘要： An image control system includes an estimation circuit, an obtaining circuit, and an image control circuit, which circuits can be at least one processor. The estimation circuit receives an output from a trained model in response to an input of an acoustic signal indicating a performance of a musical piece. The estimation circuit estimates musical performance information based on the output. The musical performance information is associated with the performance indicated by the acoustic signal relative to the musical piece. The obtaining circuit obtains manipulation information that is associated with a playback of an image. The image control circuit controls the playback of the image based on the musical performance information. The image control circuit controls the playback of the image based on the manipulation information upon obtaining the manipulation information.

摘要： A controller of a score displaying apparatus operates in a view mode displaying a score on a screen of a user I/F 12, and a writing mode obtaining information indicating writing on the score via the user I/F 12. In response to one operation specifying one grand staff by a user in the view mode, the controller performs a process of enlarging an image of an image area to which the specified grand staff belongs and displaying the enlarged image on a foreground of a center of the screen, and performs a process of switching a control mode from the view mode to the writing mode.

摘要： When a music audio to be analyzed is to be divided into a plurality of possible pattern segments based on estimated beat positions, it is divided in a plurality of different ways according to individual division models obtained by sequentially shifting the leading or first beat position of the possible pattern segments. Such division can provide plural sets of possible pattern segments with each of the sets corresponding to one of the division models. For each of the sets, comparison is made between individual possible pattern segments and individual reference performance patterns. For each of the possible pattern segments of the set, at least one reference performance pattern that matches the possible pattern segment is determined. Then, at least one combination of reference performance patterns is identified for each of the sets of possible pattern segments. One optimal combination is selected from among the identified combinations.

摘要： A musical score processing method that is realized by a computer includes receiving a control data related to displaying of a musical piece from a music processor that executes a process related to the musical piece and that is realized by a music processing program, using inter-application communication, based on a musical score processing program, and executing a display control process by displaying a musical score of the musical piece on a display device and controlling the displaying in accordance with the control data that has been received, based on the musical score processing program. The music processing program is separate from the musical score processing program.
