Abstract: A performance analysis method is implemented by a computer system and includes obtaining image data generated by imaging a percussion instrument. The performance analysis method also includes analyzing the image data to detect a change in the percussion instrument caused by striking of the percussion instrument. The performance analysis method also includes, based on the detected change, generating performance data indicating the striking of the percussion instrument. The performance analysis method also includes, based on the performance data, generating pulse data indicating a pulse structure.

Abstract: An input device includes: a first region including one or more operators to which a bass drum tone is assigned; a second region including one or more operators to which a snare drum tone is assigned; and a third region including one or more operators to which a cymbal tone is assigned. The second region and the third region are arranged in order in a direction away from the first region, and a shape of the first region, a shape of the second region, and a shape of the third region are different from one another.

Abstract: A signal processor includes an image obtainer, an estimator, and an outputter. The image obtainer obtains a performance image including playing of a drum. The estimator estimates a degree of attention attracted by the playing of the drum included in the performance image by inputting the performance image into a learning model. The learning model has been subjected to machine learning to estimate the degree of attention based on a feature quantity related to the playing of the drum. The outputter outputs the degree of attention estimated by the estimator.

Abstract: An input device includes: a detection unit configured to detect, based on a detection value obtained by detecting an operation on a pressable portion, a note-on operation and a note-off operation; and a control unit configured to set, based on at least the detection value, a control state to a valid state in which an application of an aftertouch effect is valid or an invalid state in which the application of the aftertouch effect is invalid. The control unit is configured to generate a note-on event or a note-off event based on the detected note-on operation or the note-off operation, and generate an aftertouch-on event based on a detection value output during the valid state. The control unit is configured to generate the note-on event even in a case in which the note-on operation is detected based on the detection value output during the valid state.

Abstract: An input device includes: an operation reception portion including a first group of operators and a second group of operators. In response to reception of a setting instruction, a setting process is executed to set a sound parameter for a setting target pair of operators among pairs of operators in the operation reception portion. Each of the pairs of operators includes a first operator in the first group and a second operator in the second group which are in a mutually symmetrical position relationship. The setting process includes: a first process of reflecting, for the setting target pair, the setting of the sound parameter for the first operator on the second operator; or a second process of replacing, for the setting target pair, the sound parameter that is set for the first operator and the sound parameter that is set for the second operator.

Abstract: An information processing apparatus includes a first obtainer and a recommended information outputter. The first obtainer obtains configuration information and body information. The configuration information is regarding a configuration of a drumming instrument. The body information is regarding a body of a performer playing the drumming instrument. The recommended information outputter outputs recommended information based on the configuration information and the body information obtained by the first obtainer. The recommended information is regarding a setting for playing the drumming instrument and corresponds to the performer.
