Abstract: A sound generating system in the embodiment of the invention includes an information processing terminal displaying a screen relating to a setting for controlling an electronic musical instrument determined based on a positional relation with the electronic musical instrument on a display screen and transmitting control information based on an operation performed on a touch sensor, and the electronic musical instrument performing the setting relating to sound generation according to the received control information to generate an audio signal based on the performed setting.

Abstract: A server apparatus includes a processor, configured to acquire object specifying information for specifying an object in a reality space captured by a first portable terminal, to acquire condition information including an external condition of the first portable terminal, and to acquire content information associated with the object specifying information and the condition information by referring to a database. The database stores, in association with one another, content information representing a content displayed by being superimposed on an object in a reality space captured by a second portable terminal, object information for identifying the object captured by the second portable terminal, and condition information representing a condition for displaying, in the first portable terminal, the content represented by the content information. The processor of the server apparatus is also configured to transmit the content information to the first portable terminal.
