Abstract: A signal switching apparatus is provided which is capable of performing checking in a manner that a plurality of output channels can be discriminated in checking the assignment of the plurality of output channels to buses to which signals are input. A plurality of signals input to a mix bus comprised of six buses are selectively output to two analog outputs in accordance with assignment performed by an output assigning device. First checking signals for three channels among six channels from a first oscillator are directly input to an adjuster, and first checking signals for the rest of the six channels from the first oscillator are input to a signal switching device. Second checking signals for all of three channels from a second oscillator are input to the checking signal switching device. The checking signal switching device selectively outputs the input first or second checking signals to the adjuster.

Abstract: In a digital mixer, one of channels assigned to channel strips is selected, via a select switch, from among a plurality of channels allocated to a layer selected via a layer selection switch. The selected channel is retained in a history table. Each time a history readout switch is depressed, a channel history is read out from the history table. The thus read-out channel is set as an editing channel. In a layer-linking mode, the layer to which the read-out channel is allocated is selected, and the channels contained in the layer are assigned to the channel strips.

Abstract: In a digital mixer, a standard mode or a switched mode of an input patch is selectable. When shifting from the standard mode to the switched mode is selected, input port information in input patch data stored in a current memory is converted according to a port correspondence relation indicated by conversion data. When shifting from the switched mode to the standard mode is selected, the input port information in the input patch data stored in the current memory is reversely converted to original information according to the port correspondence relation indicated by the conversion data.

Abstract: Mixer and one or more external devices, related to audio signal processing, are interconnected via a communication network, such as a LAN. For a particular one of the external devices for which communication with the mixer via the communication network is to be established, a network address unique to the particular external device and a communication protocol to be used for data communication with the particular external device are designated by entry operation by a user. Logical connection is established such that data communication is performed, in accordance with the designated communication protocol, between the mixer and the particular external device corresponding to the designated network address. Thus, data communication is performed, via the communication network, between the mixer and the particular external device for which the logical connection has been established.

In the detailed edit mode, a screen for accepting an edit operation of the parameter selected in the normal mode is displayed on a touch screen and a value of the parameter stored in a current memory is changed according to the operation sensed by the touch panel.

Abstract: When a jump instruction to display contents regarding a control out of contents in a help screen is given, if the jump instruction is given for a control with the same identification data as that of a control for which a preceding instruction is given, an explanation at a position next to a position of contents displayed in response to the preceding jump instruction is displayed on the help screen, out of the contents of a help data corresponding to the identification data of the control. If the jump instruction is given for a control with different identification from that of the control corresponding to the preceding jump instruction, an explanation at a head position, out of explanations in the help data corresponding to the identification data of the control for which the current jump instruction is given is displayed on the help screen.

Abstract: An electronic apparatus which is capable of preventing loss of edited operation data even if a user fails to perform a saving operation on the edited operation data. A set of operation data is recalled from either the original storage or the shadow storage to the current storage. Changing of the contents of the operation data stored in the current storage is reflected in the contents of a corresponding set of operation data of the n sets of operation data stored in the shadow storage. When a set of the operation data stored in the current storage is saved, the saved set of operation data is written into a storage area of the original storage and a corresponding storage area of the shadow storage.
