Abstract: When a PC connected to a mixer engine functions as an editing device to edit a configuration of signal processing in the mixer engine, components and wires included in the edited configuration of signal processing are displayed within a CAD screen on a display of the PC, and a delay amount occurring in processing corresponding to each of the components and wires when the mixer engine executes the signal processing is displayed in correspondence with each of the components and wires on the CAD screen. In this case, the delay amount corresponding to each wire is a value determined according to a result of assignment in which signal processing corresponding to each component is assigned to a plurality of signal processors in the mixer engine.

Abstract: Information entered by a user at the time of logging on is also used in a check to be performed in response to a request for use/edit of a program or data related to an additional function. Authentication information of the user using a program or data related to the additional function is included in advance in the program or data, so that, when the user has made a request for using/edit the program or data, it is checked whether or not the user is a user authorized to use the additional function, using the information entered by the user at the time of logging on and the authentication information. To perform user management for creating an account of a user using an apparatus or software and setting authorization of a user in using the apparatus or software, a plurality of users have parent-child relationships with a highest-position, root user at the top.

Abstract: In a PC that controls a mixer engine having a programmable DSP, any object such as a knob or the like is enabled to be duplicated from a control screen corresponding to various signal processing components and disposed at any position on a user control screen to make it possible to use the user control screen as a control screen editable by a user. When an object such as a knob is designated in the user control screen and a predetermined direction is issued, a menu is displayed on a display. Then, when “Open Original” is selected from the menu, it is understood that display of the control screen including an original of the designated object is directed, and the control screen is displayed on the display.

Abstract: In an apparatus having a display for supplying parameters to a mixing system, a first display control section controls the display to present a scene list containing identifications of each scene and configuration data of the mixing system specified by first specification data contained in each scene. A scene selection acceptance section accepts selection of a scene from the scene list presented on the display. A second display control section controls the display to present operation data of the mixing system specified by second specification data contained in the selected scene, such that the display presents each portion of the operation data. Each portion contains one option of the operation data specified by the second specification data in manner distinguishable from another option not specified by the second specification data.

Abstract: In a mixer system including an editing device that edits a configuration of signal processing by designating a combination of a plurality of components and a DSP that processes audio signals in accordance with the signal processing configuration edited by the editing device, when the mixer engine does not store a predetermined enabling key, audio signal processing including a protected component in the mixer engine is disabled, and when the mixer engine stores the predetermined enabling key, the audio signal processing is enabled. Further, the editing device is permitted to edit a signal processing configuration including the protected component irrespective of storage of the enabling key in the mixer engine.

Abstract: In a mixer system including: a plurality of mixer engines each provided with a programmable DSP; and a PC controlling operations of the respective mixer engines, the PC stores, as zone data, a plurality of configuration data each indicating a configuration of signal processing to be executed by one mixer engine or more out of the mixer engines under the control of the PC, accepts the selection of the zone data, and when the necessary mixer engines are in a controllable state, transfers data on a part of the aforesaid configuration which is to be assigned to each of the mixer engines, to the corresponding mixer engines. Then, when the selection of the configuration is accepted, each of the mixer engines to which the configuration is transferred is caused to execute the audio signal processing according to the selected configuration.

Abstract: A digital mixer has a custom component specified by a configuration ID. Further, the same configuration ID is provided to another custom component for ensuring compatibility of scene data which is used for operating the custom component. When a custom component of the mixer configuration is edited, the edited custom component is provided with the same configuration ID as the initial custom component before the editing. Scene data of the initial custom component can be copied to scene data of the edited custom component or vice versa provided that their configuration IDs match with each other.

Abstract: In a mixer system including a mixer engine wherein contents of signal processing can be programmed and a PC that edits the configuration of signal processing, the PC is provided with a display controller that graphically displays the edited configuration of signal processing using components for the signal processing and wires connecting nodes of the components; an accepting device that accepts designation of a node or wire whose signal is desired to be monitored, in a screen thereof; and a directing device that directs the mixer engine to output the signal from the designated node or wire to a monitoring analog signal output in accordance with the designation, and the mixer engine is provided with an outputting device that outputs a signal to the monitoring analog signal output in accordance with the direction separately from the signal processing relating to the edited signal processing configuration.

Abstract: As preset component data to perform processing on components for signal processing in a mixer engine, data for PC and data for transfer to be transferred to the mixer engine to cause the engine to perform signal processing are stored on the PC side, and data for engine is stored on the mixer engine side. When being directed to upgrade the preset component data on the mixer engine side, the PC compares the ID of each component included in the data for PC stored in the PC with the ID of each component included in the data for engine stored in the mixer engine, and, when detecting an ID existing only in the former, transfers the aforementioned data for transfer on the component corresponding to the ID to the mixer engine and causes the engine to store the data as the data for engine.

Abstract: Timer generates a first time code with a relatively high resolution. Second time code, given from a reproduction device in relation to video or music reproduced by the reproduction device, has a resolution lower than the first time code. By correcting the timer-generated first time code on the basis of the second time code, there can be generated a corrected first time code having a same over-time progression as the second time code but having a higher resolution than the second time code. Once an operator, such as a mixer, is operated at given reproduction timing of the video or music during recording, data indicative of the operation is stored in a memory along with the first time code corrected in accordance with the second time code. In reproduction, the memory is read in accordance with the first time code, corrected on the basis of the second time code.
