Abstract: In a digital mixer, a storage stores operating data including a plurality of parameters for controlling states of audio signals of a plurality of channels. A signal processor performs a mixing process of the audio signals based on the operating data. A plurality of channel strips are mounted on an operating panel in correspondence to the plurality of the channels. Each channel strip includes operators arranged for controlling a corresponding channel. A display controller displays a panel imitation portion imitating an appearance of the operating panel and including a plurality of channel strip imitation images which imitate the plurality of the channel strips and which are arranged in a positional relationship corresponding to a positional relationship of the channel strips arranged on the operating panel. A parameter setter sets a value of a specific parameter of a channel corresponding to a channel strip upon detecting that the channel strip has been manipulated.

Abstract: There are provided k operators to be used for performing parameter setting. A channel strip screen displays a plurality of parameters for each of selected k channels. In response to selection operation to select a desired one of the parameters displayed on the channel strip screen, a parameter window related to the selected parameter is opened on a display. The parameter window displays, for each of selected k channels, a parameter of a same type as the selected parameter. Each of the parameters displayed for the selected k channels is assignable to any one of the k operators.

Abstract: A parameter display portion of an acoustic signal processing apparatus (mixer) according to the present invention displays a setting of a parameter (channel group setting parameter) by use of a plurality of light-emitting display elements (LED) La through Lc. While the acoustic signal processing apparatus is under operating conditions with a setting of the parameter being established through a setting operation of an operator (on-switch) Bt, the display elements La through Lc in the entire parameter-establishable range are kept in display action. The parameter display portion is controlled such that, during the display action, the display element [(2)=La, (3)=Lb, (4)=Lc] corresponding to the established setting is displayed in the first display mode, while the other display elements [(2)=Lb and Lc, (3)=La and Lc, (4)=La and Lb] excluded from the established setting being displayed in the second display mode.

Abstract: Once a user performs touch operation on any one of knob images displayed on a display device, a CPU identifies the touch operation as first-type touch operation and starts a state where selection of a parameter represented by the touched or selected knob image is kept effective. Once termination of the first-type touch operation is detected, the CPU terminates the selection of the parameter. Further, once new touch operation is detected while the parameter is selected via the first-type touch operation, the CPU identifies the new touch operation as second-type touch operation and changes the value of the currently selected parameter on the basis of a distance and direction of movement of the second-type touch operation (rotating operation). At that time, touch operation on any other parameter image than the currently selected parameter image is made invalid.

Abstract: Once an automatic setting instruction, such as a scene recall instruction, is given for instructing that a parameter to be set via an operator member should be automatically set to a given target value, automatic setting processing, such as scene recall processing, is performed to cause the current value of the parameter, to be set via the operator member, to gradually vary toward the given target value. During that time, the given target value and the current value of the parameter to be set via the operator member are displayed on a display device simultaneously or alternately. During the automatic setting processing, the target value can be changed as desired by a user, and, as the target value is changed, the changed or new target value is displayed on the displayed device.

Abstract: On a sub-display 14c, a plurality of first user-defined keys 53, bank switch keys 51 and an edit key 52 which are software keys are displayed. Immediately below the sub-display 14c, second user-defined keys 50a to 50d which are hardware keys arranged as if the arrangement of the first user-defined keys 53 were extended are provided. The sub-display 14c also displays user-definition name areas 54 for displaying respective names of user-definitions assigned to the second user-defined keys 50a to 50d. By a manipulation of one of the user-defined keys, a function assigned to the manipulated user-defined key is executed. By a manipulation of the edit key 52, a setup screen on which the display size and the like of the first user-defined key are specified is displayed on a main display.

Abstract: Once a parameter is focused and defined as a target parameter on a main display, a utility area S-2 provided on a sub-display 14c displays a numeric keypad 56 which is a screen for inputting a value of the target parameter. The numeric keypad 56 varies depending on the type of a target parameter. When a user touches the numeric keypad 56 to input a value, the target parameter is updated with the input value.

Abstract: A digital mixer is provided with a plurality of signal processing channels each processing an audio signal in accordance with various kinds of parameters, and a plurality of channel strips each having a switch operating element and a control operating element to have one of the signal processing channels as a target channel which is to be controlled on the channel strip. The digital mixer is allowed to assign two or more channels to a channel strip at one time. When the switch operating element of the channel strip is manipulated, the channel strip switches the currently targeted channel to another channel different from the currently targeted channel among the channels assigned to the channel strip. When the control operating element of the channel strip is manipulated, a parameter value of the targeted channel of the channel strip is changed in accordance with the manipulation of the control operating element.

Abstract: On a digital mixer, each channel is given a channel definition defining whether the channel is to be used individually or to be used as a group along with a certain channel. When a channel strip to which a user desires to assign and a channel which the user desires to assign are selected, it is determined whether the selected channel is a channel to be used individually or to be used as a group. When it is determined that the selected channel is to be used as a group, channels belonging to the group are assigned to the selected channel strip so that the user can concurrently control respective channels' values of a parameter by use of an operating element provided on the selected channel strip.

Abstract: Each of level meter block images 21 to 2m arranged on a touch panel display 1 displays, as a bar graph, respective signal levels of channels of a corresponding one of m blocks into which a plurality of channels are divided. The level meter block images 21 to 2m also serve as assignment selection buttons of an assignment selection portion 2. For each level meter block image, an image generation portion 8 generates not only an image of a bar graph but also an image which indicates respective color indicators of the respective channels such that, when a signal type of a channel indicates that there is a signal correlation between the channel and its neighboring channel, the channel has a color indicator of a connected shape shared with the neighboring channel, and synthesizes these images to output the synthesized image to an image display control circuit 3.

Abstract: In a mixing system where a console, engine and I/O devices, each possessing a plurality of supply sources and destinations, are connected to a network, a plurality of transmission channels of the network are allocated to the individual devices. In response to human operator's connection instruction given via the console for instructing a connection between a supply source possessed by one of the devices and a supply destination possessed by another of the devices, the device possessing the supply source transmits an audio signal of the supply source to the network using one of the transmission channels allocated to the device. The device possessing the signal supply destination, for which the connection instruction has been given, receives the audio signal transmitted via the transmission channel and supplies the received audio signal to the supply destination.

Abstract: A method is designed for controlling windows of a mixer device including a processing unit, an operating panel, and a touch panel provided on the operating panel, the touch panel functioning as both a display part for displaying windows and an input part for inputting instructions. The method is performed by the processing unit as follows. First, a determining step determines whether or not any window has already been displayed on the touch panel when an instruction to display a new window is made. Then, a first displaying step displays the new window when no window has already been displayed, and otherwise displays, when a window has already been displayed, the new window at foreground while displaying at least a title bar of a window that has already been displayed. Further, a second displaying step displays a close button only on a foreground window among windows displayed on the touch panel and deactivates display of a close button for each window behind the foreground window.

Abstract: A sub-console 1200 has a lower channel strip group 40 on a front panel 1202, and an upper channel strip group 42 on a rear panel 1206. Left and right displays 52 and 54 are provided between the upper and lower channel strip groups 42 and 40. Either one of the parameter of the upper and lower channel strip groups 42 and 40 is displayed on the left and right displays 52 and 54. With this structure, the width of the sub-console 1200 can be reduced, and the positional correspondence relationship between the respective channel strip groups and the left and right displays 52 and 54 can be maintained. Accordingly, a high operability can be realized.

Abstract: Once a mixer is set in a predetermined operation, an input-logical-channel selecting section supplies sound signals, input via a cascade input terminal, to an input signal processing section via an input patch section, so that the sound signals can be mixing-processed as sound signals of normal input channels. At the same time, a portion of sound signals input via an input terminal are supplied to mixing buses, so that these sound signals can be handled as cascade-related signals. In accordance with a model of another, or cascaded-to, mixer, arrangements are made such that normal-input/output-channel input terminals can be assigned to cascade input/output purposes. With a block diagram display section indicating what signals the individual input/output terminals are currently assigned to within the mixer, a user can grasp at a glance the current assignment state.

Abstract: A clip state display method which is capable of quickly identifying a clipping point and changing settings of signal processing. It is detected whether a clip occurs in any of signals of a plurality of input channels on which at least one of signal processing and mixing processing is performed. A block diagram showing functions of at least one of the signal processing and the mixing processing is displayed. Functions of at least one of the signal processing and the mixing processing in which the clip has occurred are displayed on the block diagram.

Abstract: In sequence data composed of a plurality of event sets with their execution sequence predefined, each of the event sets includes event data indicative of an event to be executed and trigger data defining timing for executing the event. Once a user manually instructs progression instructing operation while the individual events are being executed in accordance with the timing defined by the corresponding trigger data, the next event is executed immediately even before arrival of the next event execution timing. According to another aspect, the trigger data include trigger data of a first type that defines the event execution timing the event by use of an absolute time and trigger data of a second type that defines the event execution timing by use of a relative time between the events, and the sequence data may mixedly include the trigger data of the first and second types. Any one of the two time information can be used appropriately in accordance with characteristics of the individual events.

Abstract: Once bookmark registration is instructed by user operation while any detailed setting window is being displayed on a background screen on a display of a digital mixer, only the currently-displayed detailed setting window is bookmark-registered. Thus, once bookmark call operation is performed while a desired background screen is being displayed, the currently-displayed background screen is maintained as-is, and the called detailed setting window is displayed on the background screen. Further, bookmark registration can be made in association with a mixer channel, and, in response to bookmark call operation, parameters of the associated channel can be called and displayed.

Abstract: In a digital audio mixer, a link group assigner assigns one or a plurality of link groups exclusively to channels of the digital audio mixer. An operating data setter sets a value of an operating data element for each of concerned channels to the same value when the operating data element is placed in a link state and when the same link group is assigned to the concerned channels. An operating data changer operates when a value of an operating data element of one channel is changed to a specific value and when the operating data element is placed in the link state, for changing a value of a corresponding operating data element of another channel belonging to the same link group as the one channel to the specific value. An image data output unit displays a screen containing graphic symbols representing the respective channels.
