Description

The present invention relates to an electronic music apparatus, and more particularly to an electronic music apparatus having a touch panel.

Conventionally, in an electronic musical instrument, various functions are set by operating a hardware switch installed on a panel. Since the switch to be operated protruded on the panel or formed a recess, even a visually impaired user could find the position by hand. For this reason, it was possible to manage the setting of the electronic musical instrument somehow when the operation procedure was known.

  In recent electronic musical instruments, in order to make the setting function between devices flexible while sharing parts between models (a new function can be added via a communication network such as the Internet) Or, in order to make the design clear, the number of displays and switches that are made into a touch panel and arranged in software is increasing for the purpose of effectively utilizing the space on the panel.

  In the electronic musical instrument employing the touch panel as described above, it is difficult for a visually impaired person to recognize the correspondence of the position, and it is very difficult to set the electronic musical instrument.

  In order to enable a visually impaired person to use a touch panel, it has been proposed to wear a film having irregularities on the surface of the touch panel so as to be peeled freely (see, for example, Patent Documents 1 and 2). In addition, it has been proposed to provide a member for recognizing the boundary of each switch on the touch panel or to provide different uneven patterns on the surface at a plurality of locations (for example, see Patent Documents 3 and 4). Furthermore, what formed the braille information in the peripheral part of the display surface of a touch panel is proposed (for example, refer patent document 5). Moreover, what outputs the information of each switch arrange | positioned on a touch panel as an audio | voice is proposed (refer patent documents 6-9).

The display 14 can display selection information for setting the electronic music apparatus 1 and music information such as a score and lyrics. The touch operator image displayed on the display 14 corresponds to a touch operator 23 described later.

  The touch operator 23 is an operator that detects a user's pressing operation on a touch panel operation surface provided on the surface of the display 14 and outputs position information (for example, xy coordinates) of an operated position. In this embodiment, the position information output from the touch operator 23 is associated with the command executed by the electronic music apparatus 1. The association between the position information and the command changes each time according to the information displayed on the display 14. In this embodiment, the display on the touch operator 23 and the display 14 is collectively referred to as a touch panel.

New installation and version upgrade of control programs and the like can be easily performed.

  In the present embodiment, the external storage device 15 or the ROM 8 stores various display data of the electronic music device 1 for storing display data of the touch operator image for the touch panel and commands associated with the display coordinates of the display data. Multiple pages are stored according to the function. Furthermore, the external storage device 15 or the ROM 8 can store a plurality of automatic performance data and related data (data related to music data such as musical score data and fingering information). The command in the screen data may be associated with the display data itself, not the display coordinates of the display data. In this case, even if the display coordinates of the display data are changed, the correspondence between the display data and the command is maintained.

  The MIDI interface (MIDI I / F) 16 can be connected to a MIDI device 17, other musical instruments, audio devices, computers, and the like, and can transmit and receive at least MIDI signals. The MIDI interface 16 is not limited to a dedicated MIDI interface, and may be configured using a general-purpose interface such as RS-232C, USB (Universal Serial Bus), IEEE 1394 (Eye Triple E 1394). In this case, data other than MIDI messages may be transmitted and received simultaneously.

  The MIDI device 17 is an acoustic device, a musical instrument or the like connected to the MIDI interface 16. The form of the MIDI device 17 is not limited to a keyboard instrument, and may be a string instrument type, a wind instrument type, a percussion instrument type, or the like. In addition, the sound source device, the automatic performance device, and the like are not limited to those built in one electronic musical instrument body, but each is a separate device, and each device is connected using a communication method such as MIDI or various networks. May be.

  The tone generator circuit 18 responds to music content recorded in the external storage device 15, ROM 8, RAM 7, or the like or performance signals supplied from the performance device 22 or MIDI device 17 connected to the MIDI interface 16, MIDI signals, and the like. A musical sound signal is generated and supplied to the sound system 20 via the effect circuit 19.

  The effect circuit 19 gives various musical effects to the musical sound signal supplied from the sound source circuit 18. The sound system 20 includes a D / A converter and a speaker 20 s (FIG. 2), converts a digital musical tone signal supplied to an analog format, and generates a sound.

  The communication interface 21 can be connected to a LAN (local area network), and can be connected to a communication network 3 such as the Internet via a provider 51, and the service providing server 55 and the like can be connected via the communication network 3. It can be connected to various servers.

  The communication interface 21 and the communication network 3 are not limited to wired ones and may be wireless. Moreover, you may provide both. The communication interface 21 may be a built-in one or a detachable one such as a PC card.

  The service providing server 56 is a server provided on the communication network 3 and is, for example, a web server such as an HTTP server. The service providing server 56 stores a large number of automatic performance data and related data, screen data, device setting data, and the like, and distributes them in response to a request from the electronic music apparatus 1 connected to the service providing server 56 via the communication network 3.

  FIG. 3 is a conceptual diagram showing the configuration of the automatic performance data PD of this embodiment. The automatic performance data PD is data stored in the external storage device 15 or the ROM 8 of FIG. Further, it can be downloaded from the service providing server 56 of FIG.

  The automatic performance data PD includes initial setting information ISD including information on data contents, reproduction restrictions, coordinate information CID including coordinates for touch operation, and performance information PID including pronunciation instruction information.

  The performance information PID is, for example, data for automatic performance conforming to the MIDI standard, and at least a key-on event, a key-off event, and time information (timing data) thereof are recorded. For example, event data such as pitch bend data and expression data can also be recorded.

  FIG. 4 is a diagram for explaining the coordinate information CID in FIG. 4A shows a format of the coordinate information CID, and FIG. 4B is a plan view showing coordinates on the touch panel (the display 14 and the touch operator 23).

  The coordinate information CID is data compliant with the MIDI standard for operating the touch panel. The coordinate information CID has a format of “F0, 43, 70, 78, 45, x coordinate, y coordinate, on / off, F7”, for example, as shown in FIG.

  The x coordinate and the y coordinate do not necessarily match the number of dots of the display 14 in FIG. 1. For example, when the resolution of the display 14 is 800 × 480 dots, the x coordinate is 0 to 99, and the y coordinate is 0 to 0. 79, or the x coordinate can be set to 0 to 15 and the y coordinate can be set to 0 to 11 as shown in FIG. By doing so, it is possible to cope with a case where the resolution changes in the future.

  On / off is a parameter for designating on / off of the touch operator 23 corresponding to the position designated by the x coordinate and the y coordinate. For example, 0 = on, 1 = off, 2 = on / off Switch.

  As shown in FIG. 4B, when the switch SW2 is turned on, the coordinate information CID is “F0, 43, 70, 78, 45, 05, 01, 0, F7”. When the switch SW2 is turned off, the coordinate information CID is “F0, 43, 70, 78, 45, 05, 01, 1, F7”. When the switch SW2 is turned on / off, the coordinate information CID is The information CID is “F0, 43, 70, 78, 45, 05, 01, 2, F7”. Note that the x coordinate and the y coordinate may be coordinates of an arbitrary point included in the operated switches (SW1 to SW16).

  In this embodiment, as will be described later, when the automatic performance data PD including the coordinate information CID is received or read out, the coordinate information CID is acquired from the automatic performance data PD, and the coordinates indicated by the coordinate information CID are obtained. The same processing as when the switches (SW1 to SW16) corresponding to is turned on / off is performed.

  Note that the coordinate information CID may be configured as MIDI data alone, for example, in addition to the coordinate information CID included in the automatic performance data PD. Further, it may be recorded as event data in the performance information PID.

  Further, in this embodiment, when the touch operator 23 is operated, the coordinates of the operated position (operation coordinates) are specified, and the coordinates indicating the specified operation coordinates and function on / off by the operation are specified. The information CID can be output as MIDI data in the format shown in FIG. 4A, for example, via the MIDI interface 16 in FIG. Note that it is not always necessary to output the coordinate information CID. For example, the presence or absence of output may be switched according to a user instruction.

  For example, when the switch SW2 is turned on, “F0, 43, 70, 78, 45, 05, 01, 0, F7” is output as the coordinate information CID, and when the switch SW2 is turned off, “F0, 43, 70, 78, 45, 05, 01, 1, F7 ", and when switching on / off," F0, 43, 70, 78, 45, 05, 01, 2, F7 "is output.

  In the conventional method of specifying the type and value of a parameter to be changed by MIDI data, it has not been possible to view a web page using a web browser or an undecided screen at the time of product shipment. By transmitting / receiving the coordinates of the position desired to be operated and on / off at the coordinates as coordinate information CID, it is possible to view a web page using a web browser or to an undecided screen at the time of product shipment.

  Further, for example, by describing coordinate information for items (switches) displayed on the display 14 in a text manual for visually impaired persons, the coordinate information CID is transmitted to the electronic music apparatus 1 even for visually impaired persons. By doing so, the touch panel function of the electronic music apparatus 1 can be used.

  As described above, the coordinate information CID enables, for example, remote operation of the touch panel and operation with sequence data using MIDI data.

  FIG. 5 is a plan view for explaining a marker 24 for a visually impaired person according to an embodiment of the present invention.

  The visually impaired person marker 24 is a plurality of convex portions provided at equal intervals on at least two sides (four sides in the present embodiment) in the vertical and horizontal directions of the peripheral portion of the display 14. The marker 24 only needs to be recognizable by touch or the like without relying on vision, and is not limited to a protrusion but may be a groove or the like. In the present embodiment, the position of the marker 24 is easily grasped by changing the shape of the marker 24 every other horizontal direction and vertical direction.

  On the upper part of the marker 24, a display indicating what number the marker 24 is is provided. This display is preferably in a form that can be recognized by a visually impaired person, for example, displayed in braille.

  FIG. 6 is a conceptual diagram for explaining the rearrangement of the switches SW displayed on the display 14 according to the embodiment of the present invention.

  FIG. 6A is an example of a normal arrangement of the switches SW1 to SW12. The switches SW1 to SW8 and the switches SW9 to SW12 have different sizes and do not correspond to the marker 24 installed at the peripheral edge. In such a switch arrangement, it is difficult for a visually handicapped person to find a switch that the user wants to operate. In addition to the example shown in the figure, it is often difficult for visually impaired persons to find a switch by hand, such as a switch being small or a sense of the switch being narrow, in a display that does not consider visually impaired persons.

  Therefore, in the present embodiment, first, as shown in FIG. 6B, the display area of the touch panel (the display 14 and the touch operator 23) is equally divided so as to correspond to the marker 24 installed in the peripheral portion (this embodiment). In the example, it is divided into 16 equal parts), and each area is defined as A1 to D4. Thereafter, as shown in FIG. 6C, the switches SW1 to SW12 are assigned to the divided areas. The assignment of the switch SW is performed by displaying an image for the switch in each area and associating the coordinate range of the area to be assigned with a command corresponding to each switch. This switch rearrangement is a process performed in steps SA15 to SA18 in FIG.

  Thus, by rearranging the switches, the shapes and sizes of the switches SW are made uniform, and the switches SW are arranged at equal intervals. Moreover, since each switch SW comes to correspond to the marker 24, it becomes easy for a visually handicapped person to grasp the position of the switch SW.

  By performing this rearrangement process, even when a web page is browsed using a web browser or an undecided screen is newly added at the time of product shipment, a screen that can be easily operated by a visually impaired person can be obtained. Further, even if the screen is not dedicated to the electronic music apparatus 1, it can be converted into a screen corresponding to the marker 24 installed in the electronic music apparatus 1.

  FIG. 7 is a plan view showing the auxiliary sheet 25 according to the embodiment of the present invention. The auxiliary sheet 25 is used when each of the switches SW is rearranged so as to correspond to the marker 24 as shown in FIG. The auxiliary sheet 25 is, for example, a transparent sheet with protrusions 26, and the protrusions 26 are provided in regions A1 to D4 shown in FIG. 6B. A visually handicapped user can easily operate the touch panel by tracing on the sheet and pressing the projection 26.

  The auxiliary sheet 25 is not limited to the rearranged switch SW, but can be prepared for various arrangements, but by combining with the rearrangement process, one corresponding to the marker 24 is prepared. Just to do so, you will be able to handle any screen.

  FIG. 8 is a flowchart showing the main processing according to this embodiment. This main process is started when the electronic music apparatus 1 is turned on.

  In step SA1, the main process is started, and initialization is performed in step SA2. Here, for example, various flags, buffers, registers, etc. are initialized.

  In step SA3, it is determined whether coordinate data (for example, coordinate information CID in FIG. 4) has been received. If coordinate data has been received, the process proceeds to step SA4 indicated by an arrow of YES, and if not received, the process proceeds to step SA5 indicated by an arrow of NO.

  In step SA4, an operation of the touch panel (touch operator 23 in FIG. 1) is detected. If an operation on the touch panel is detected, the process proceeds to step SA5 indicated by an arrow of YES, and if an operation is not detected, the process proceeds to step SA7 indicated by an arrow of NO.

  In step SA5, the operation coordinates of the touch panel operation detected in step SA4 (the x coordinate and the y coordinate of the position where the touch operator 23 is pressed) are specified. In step SA6, a command associated with the operation coordinate specified in step SA5 is specified. Information regarding the association between the coordinates in the touch panel and the command is recorded in the screen data of the currently displayed screen, or is recorded in the external storage device 15 or the like as a table in step SA12 or step SA16 described later. Thereafter, the process proceeds to step SA9.

  In step SA7, the operation of the panel operator (panel operator 12 in FIG. 1) is detected. If an operation of the panel operator is detected, the process proceeds to step SA8 indicated by an arrow “YES”, and if an operation is not detected, the process proceeds to step SA25 indicated by an arrow “NO”.

  In step SA8, the command assigned to the panel operator whose operation is detected in step SA7 is specified. Thereafter, the process proceeds to step SA9.

  In step SA9, it is determined whether or not the command specified in step SA6 or step SA8 is a command accompanied by a screen change. If the command is accompanied by a screen change, the process proceeds to Step SA10 indicated by a YES arrow. If the command is not accompanied by a screen change, the process proceeds to Step SA19 indicated by a NO arrow.

  Here, the command accompanied by the screen change is not only a command for instructing a direct screen change such as a page change of the display screen, for example, but it is necessary to update to a new screen to display the detailed parameters of the command Contains commands that have For example, when a timbre group is designated on the first screen on the timbre selection screen and a specific timbre within the group is selected on the second screen, the timbre group is selected on the first screen. It is a command with a change.

  In step SA10, screen data of a new display screen is acquired (for example, downloaded from the service providing server 56 via the communication network 3 in FIG. 1) or read from the external storage device 15 in FIG. Here, the screen data is data including image data of the touch operator image to be displayed on the display 14 and a command associated with the display coordinates of the touch operator image.

  In step SA11, it is determined whether or not the command specified in step SA6 or step SA8 is a command for shifting to the rearrangement mode (or the current display mode is the rearrangement mode). In the case of the rearrangement mode, the process proceeds to step SA14 indicated by an arrow of YES, and in the case of not the rearrangement mode, the process proceeds to step SA12 indicated by an arrow of NO.

  In step SA12, the touch operator image is displayed at a predetermined position (a position specified by the screen data) on the display 14 based on the screen data acquired or read in step SA10. In step SA13, a command is assigned to the display coordinates of the touch operator image displayed in step SA12 based on the screen data acquired or read in step SA10. Thereafter, the process proceeds to Step SA18.

  The processing in steps SA14 to SA17 is the touch switch rearrangement processing described with reference to FIG.

  In step SA14, the command assigned to the touch operator (the command included in the screen data acquired or read in step SA10) is extracted. In step SA15, the number of touch display surfaces (the display surface of the display 14 and the touch operator 23) is a predetermined number (for example, the number corresponding to the marker 24 shown in FIG. 3, and four markers in the horizontal direction and four markers in the vertical direction). If 24 is installed, it is equally divided into 16). In step SA16, the commands extracted in step SA14 are assigned to the areas divided in step SA15 one by one. If the command extracted in step SA14 is larger than the number of areas divided in step SA15, the command is displayed over a plurality of pages. In step SA17, the touch operator image is displayed in the area to which the command is assigned in step SA16. Thereafter, the process proceeds to Step SA18.

  In step SA18, the item name, area (or coordinate) value, and page name (for example, “tone selection screen”) of each command assigned to the touch operator are output as sound. This sound output is produced using, for example, the speaker 20s shown in FIG. 2 via the sound source circuit 18 and the sound system 20 shown in FIG. In this way, by outputting the command item name and area (or coordinate) value as a voice, even a visually handicapped person can recognize the position of the touch operator and the command item name. Further, by combining with the marker 24 shown in FIG. 3 and the auxiliary sheet 25 shown in FIG. 7, even a visually handicapped person can easily operate the touch panel.

  Note that the sound generation processing by sound output here may be such that sound data is output to the outside via, for example, the communication interface 21 of FIG. 1 and sounded by an external device.

  The voice output here is, for example, text data of the command item name recorded in the screen data (text data corresponding to the command item name to be displayed on the display 14) by a known technique. It is a thing.

  In step SA19, it is determined whether or not the command specified in step SA6 or step SA8 is a performance data selection command. If it is a performance data selection command, the process proceeds to step SA20 indicated by a YES arrow, and the selected performance data is read from the external storage device 15 or downloaded from the service providing server 56 via the communication network 3. If it is not a performance data selection command, the process proceeds to step SA25 indicated by a NO arrow.

  In step SA21, it is determined whether or not the command specified in step SA6 or step SA8 is a command related to a performance data reproduction instruction. If it is a reproduction instruction, the process proceeds to step SA22 indicated by an arrow of YES. If it is an instruction to reproduce the performance data, the reproduction flag is set to “1”, and if it is an instruction to stop reproduction, the reproduction flag is set to “0”. Then, the process proceeds to step SA25. If it is not a reproduction instruction, the process proceeds to step SA23 indicated by a NO arrow.

  In step SA21, it is determined whether or not the command specified in step SA6 or step SA8 is an instruction to end the electronic music apparatus 1 (main process). If it is an end instruction, the process proceeds to step SA30 indicated by a YES arrow, and this main process is ended. If it is not an end instruction, the process proceeds to step SA24, and other processing of the electronic music apparatus 1 is executed. Other processing includes, for example, various file operations other than the reproduction instruction, tone color setting, device setting, and the like. After executing the other processes, the process proceeds to step SA25.

  In step SA25, it is determined whether or not the reproduction flag is “1”. When the reproduction flag is “1”, the process proceeds to step SA26 indicated by a YES arrow. When the reproduction flag is “0”, the process proceeds to step SA28 indicated by a NO arrow.

  In step SA26, it is determined whether the automatic performance data to be reproduced includes coordinate data (coordinate information CID in FIG. 4) or whether the event at the current timing is coordinate data (coordinate information CID in FIG. 4). If the coordinate data is included or if the current event is coordinate data, the process returns to step SA5 indicated by the YES arrow, and the subsequent processing is repeated. If the coordinate data is not included or the current event is not coordinate data, the process proceeds to step SA27 indicated by a NO arrow. As shown in FIG. 3, when the coordinate information CID is recorded separately from the performance information PID, the determination at this step SA26 is only whether or not the current event is coordinate data. Just judge.

  In step SA27, processing corresponding to other events is performed. For example, if the event at the current timing is a note-on event, a tone generation process for a musical sound instructed by the note event is performed. Thereafter, the process proceeds to Step SA28.

  In step SA28, the operation of the performance operator 22 shown in FIG. 1 is detected. If the operation of the performance operator is detected, the process proceeds to step SA29 indicated by a YES arrow, and processing corresponding to the detected operation is performed. Thereafter, the process returns to step SA3. If the performance operation is not detected, the process returns to step SA3 indicated by the NO arrow and the subsequent processing is repeated.

  As described above, according to the embodiment of the present invention, a marker is installed on the peripheral part of the touch panel, and a switch on the touch panel is rearranged so as to correspond to the marker, so that even a visually handicapped person can communicate via a communication network or the like. It is possible to prepare and operate a touch-panel-operated electronic music apparatus that can acquire and display a new screen. Furthermore, if the auxiliary sheet 25 is used, the touch panel operation by the visually impaired person becomes easier.

  In addition, according to the embodiment of the present invention, by outputting the item name and area (or coordinate) value of each command by voice, the position of the touch operator and the item name of each command can be obtained even for a visually impaired person. Can be recognized.

  Further, according to the embodiment of the present invention, touch panel control information (coordinate information CID) can be transmitted and received using a commonly used data format such as MIDI data. Control by is possible.

  In the embodiment, when the coordinate information CID is acquired, the command is always executed according to the coordinate information CID. However, this function may be arbitrarily turned on / off by the user.

  In the embodiment, the coordinate information CID is described as turning on / off the function assigned to the designated coordinate. However, numerical value input may be performed instead of turning on / off.

  Although the present invention has been described with reference to the embodiments, the present invention is not limited thereto. It will be apparent to those skilled in the art that various modifications, improvements, combinations, and the like can be made.
