Abstract: 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.

Abstract: A control device in one embodiment includes a first transmission unit, a first receiving unit, and a first generation unit. The first transmission unit is configured to transmit first performance data including contents of playing a keyboard instrument at a first communication base to a second communication base. The first receiving unit is configured to receive second performance data from the second communication base. The first generation unit is configured to generate a drive signal to produce a sound in accordance with the second performance data and output the drive signal to a sound generation device at the first communication base. At least one of the first performance data and the second performance data includes a key position signal indicating a key press amount on the keyboard instrument.

Abstract: A method of processing sound includes arranging objects of a plurality of performers in a virtual space. The method also includes receiving a plurality of sound signals respectively corresponding to the plurality of performers. The method also includes obtaining, using a trained model, sound volume adjustment parameters respectively for the plurality of performers. The trained model is trained to learn a relationship between each sound signal, among the plurality of sound signals, that corresponds to each performer of the plurality of performers and each sound volume adjustment parameter, among the sound volume adjustment parameters, that corresponds to the each sound signal. The method also includes adjusting and mixing sound volumes respectively of the plurality of sound signals based on the sound volume adjustment parameters obtained using the trained model.
