It may be. Further, as shown in FIG. 2, the recording / reproducing function 1a of the recording apparatus 1 described with reference to FIG. The performance recording system according to the present invention is realized by software (program) that executes the recording / reproducing function of the recording apparatus 1 described with reference to FIG. Therefore, a desired type of performance recording system can be configured by installing the necessary equipment on the personal computer.

[Operation during recording]
In the performance recording system according to one embodiment of the present invention, a monitoring task is started by interruption at predetermined time intervals by a timer 11 called “timer 1 interrupt” in accordance with a performance recording program. It is monitored whether or not the performance information Di is input. Thus, when the performance information Di is input, the performance information (performance operation information) Di input based on the performance operation and its management data are recorded in the external storage device 14 in accordance with a predetermined condition. FIG. 3 shows a configuration example of the recording information.

  The performance information Di input to the performance input function section A based on the performance operation is composed of performance event information D1, D2,..., Dn as shown in FIG. Time information Tm: T1, T2,..., Tn representing the input times of performance event information (hereinafter simply referred to as “performance events”) D1, D2,. The recording control function unit C combines the time information Tm: T1, T2,..., Tn detected by the time detection function unit B and the input performance information Di: D1, D2,. Temporarily store in a temporary storage area (buffer area). Here, when there is no input of performance information Di for a predetermined period (for example, 10 seconds), a plurality of performance information (performance events) temporarily stored in the buffer area are collected together as a performance recording file (“performance data”). It is stored in the performance data storage area (also simply referred to as “storage”) of the external storage device (recording medium) 14 as Df, and file information Fd corresponding to the performance recording file Df is constructed in the external storage device 14. Register in the performance recording database.

  In this case, for example, as shown in FIG. 3 (2), the performance recording file Df includes time information T1, T2,..., Tn between adjacent performance events D1, D2,. T2 to T3,..., Tn-1 to Tn are collected in the SMF format converted into the relative time Δt. The file information Fd registered in the database is information in which one record is composed of “performance start time T1, performance end time Tn, file name” as shown in FIG. 3 (3).

The file name of the performance recording file Df may be in any form as long as it is a unique name (which can be distinguished from other files). Since the file name is only necessary for the system, it may be a name that does not make sense to the user. For example, the following values can be given.
(1) Character string indicating the storage time:
For example, “20061211121442.mid” (saved at 12:14:42 on December 11, 2006).
(2) Character string representing recording time interval:
For example, “20061211121021-20061211121441.mid” (Recording started at 12:10:21 on December 11, 2006 and ended at 12:14:41).
(3) Unique random value that does not overlap with other files:
For example, “23923234.mid”.

  As described above, in the performance recording system according to the embodiment of the present invention, the performance information Di based on the operation of the performance operator 2a is input during recording (A). Times Tm = T1 to Tn at which Di is input are detected (B), and a series of input performance information Di = D1 to Dn is automatically set as a performance recording file Df, and time information Tm = indicating the detection time. T1 and Tn are both recorded in the storage means 14 as file information Fd (C). At the time of reproduction, when the time is designated (D), the performance recording file Df corresponding to the designated time is retrieved from the storage means 14 (E), read / reproduced, and output as output performance information Do (F). Also, for the input time Tm = T1 to Tn, the time when the performance information Di = D1 is input after no performance information is input for a predetermined period is set as the performance operation start time Tm = T1, and the performance information Di is input. Thereafter, the input time of the last performance information Di = Dn when no performance input continues for a predetermined period is recorded as the end time Tm = Tn. Then, at the time of reproduction, the performance information Df; Do = D1 to Dn included in the section Tm = T1 to Tn whose designated time is the start to end time is searched.

[1 day view screen and monthly view screen]
In the performance recording system according to one embodiment of the present invention, various screens for displaying and retrieving recorded data can be displayed on a display (display) having a touch panel by a performance recording program. 4 to 6 are diagrams for explaining various screens used in the performance recording system according to one embodiment of the present invention. In this performance recording system, two types of screens called “daily view screen” and “monthly view screen” as illustrated in FIG. 4 are used to display recorded data (file) on the display 19a. be able to. In the “daily view screen”, the display target can be switched to “today” / “designated date” / “filter” according to the user operation on the screen, and the “today view screen” / “designated” respectively. Called “day view screen” / “filter view screen”.

  The “daily view screen” is a screen used for performing a recording state of the performance recording file Df for each day and a reproduction instruction for the recorded performance recording file Df. As illustrated in FIG. 4A, the “daily view screen” includes a main display area (track view display area) Ar positioned in the middle in the vertical direction of the screen, and attention (center) time notation Tc (upper left of the screen). And operation buttons B1 to B4 (lower and upper right of the screen). The track view display area Ar is divided into a plurality of areas (for example, three areas) in the vertical direction, and a recording state (for example, the previous day, today, and the next day) of a specific date is displayed for each of the divided areas (tracks). The

  The time notation Tc displays the time position (current) of the currently focused track in the track view display area Ar, and is appropriately updated according to scrolling of the track view display area Ar. That is, the time notation Tc represents the current (= the date and time corresponding to the center of the screen), and in the example of FIG. 4A, assuming that the current time is “2006/12/11 13:23”, one hour before that "2006/12/11 12:23" is shown as a central time (attention time) Tc. In addition, operation buttons B1 to B4 in which “calendar”, “setting”, “search”, and “today” are written are “monthly view screen”, “setting screen”, “search screen”, and “to be described later”, respectively. This is a button for switching the screen display to “today's view screen”.

  The “daily view screen” displays a view corresponding to a part of a large view in which one or more tracks that can be displayed on the screen are arranged, with the track view display area Ar as a “window”. The content displayed in the track view display area Ar of the “daily view screen” is also referred to as “current view”.

  The “today view screen” (not shown) is a screen that is switched when the “today” button B4 displayed on the upper right of the “daily view screen” or the “monthly view screen” is operated. It can be displayed as a default screen at the start of the performance recording process, and is also called a “basic view screen” or a “basic track view screen”. In the “Today's view screen”, the current time is set at the center of the time axis of the track view display area Ar, and the current view is set to the previous (previous) day, the present (present) day, and the next day (next day). ) The recording state of the performance recording file Df corresponding to each day is displayed, and is updated and automatically scrolled in real time so that the entire view automatically moves to the left as the time measured by the timer 11 elapses.

  On the other hand, on the “designated date view screen”, the day (or time) designated by the scroll operation of the “daily view screen” or the date designation operation on the “monthly view screen” as will be described later as the current view. ), The recording state of the performance recording green file Df corresponding to each of the previous day, today, and the next day is displayed. The “1-day view screen” illustrated in FIG. 4A is the “designated date view screen”. Further, on the “filter view screen”, as a current view, a part of the recording state (filter result) of the performance recording file Df that matches a search condition specified by a user operation in a search process described later is in a predetermined order. Arranged and displayed.

  As described above, the “today view screen” and the “designated date view screen” display a part of a large view in which tracks corresponding to all the dates and times that can be displayed are arranged in chronological order. The time of interest (current) is different depending on whether it is “current time” that changes from moment to moment or a specific date Tc. In other words, the “Today's View Screen” updates the track status centered on the current time in real time and displays it in the current view, whereas the “Specified Date View Screen” tracks the track centered on a certain date and time. The difference is that the state of is statically displayed in the current view. On the other hand, the “filter view screen” is different from these two modes (today's view screen and specified date view screen) in that the current view displays a track display in which the display target is limited to only tracks that match the search conditions. Different.

  In the “1 day view screen”, the plurality of tracks displayed in the track view display area Ar substantially correspond to a specific date. In the “designated date view screen” illustrated in FIG. December 10, 2006, December 11, 2006, and December 12, 2006. Each track is composed of time lines L1 to L3 and file display blocks Br and Bra with the horizontal direction of the screen as the time axis, and the file display blocks Br and Bra indicating the performance recording file Df are displayed along the time line. .

  At the top of the track view display area Ar, a plurality of time display tags Tg and time display lines (dotted lines) representing the time position (time position) of the track view are displayed in the left-right direction, and the example of FIG. Then, time positions of 11:30, 12:00,..., 13:30 are shown at intervals of 30 minutes. The display position and display contents of the time display tag Tg are updated according to the scrolling of the current view. A date corresponding to the central position of the time axis of each track is displayed at the left end of each track. The file display blocks Br and Bra displayed along the time lines L1 to L3 of each track have their head display positions coincided with the performance start time T1 of the corresponding performance recording file Df, and the horizontal direction of the block The length is displayed so as to correspond to the recording time zone (recording time zone) of the corresponding performance recording file Df, that is, the performance start time T1 to the performance end time Tn. The symbol “Br” of the file display block indicates that the performance recording file Df corresponding to this block Bra is being reproduced, distinguishing it from the symbol “Br” of other blocks.

  In this system, as described above, the input operation unit 15 includes a touch panel on the entire display screen of the display 19a, and is configured to detect a touch operation or a drag operation on the screen. Therefore, when a touch operation is performed by the user, for example, when the user's finger or stylus pen is brought into contact with the touch panel and then released at that position, the touch operation is detected and touched on the screen. Perform processing corresponding to the selected screen position. For example, when a file display block Br, Bra in the track view display area Ar is touched on an arbitrary “daily view screen”, a playback target is designated by this operation and the performance recording file Df corresponding to the block is displayed. When the reproduction is started or stopped and various buttons B1 to B4 are touched, a function corresponding to each button is executed.

  Here, when an arbitrary file display block Br (Br) is touched by the user, the entire track view is automatically set so that the touched file display block Br (Br) becomes the center position of the track view display area Ar. In addition, the display of each part such as the time notation Tc and the time display tag Tg is also updated. For example, in the “today's view screen” as of December 11, 2006 at 13:23, when a touch operation is performed on the file display block Bra on the current time line L2 in the center track, FIG. As shown in the “designated date view screen” illustrated in FIG. 5, the current time = 13: 23, which has been at the center position of the time axis, moves to the right, and the center of the block Bra, that is, the center time (attention time) Tc. The track view is shifted so that = 12: 23 is at the center of the time axis.

  In this case, the block Bra designated for reproduction is not only displayed at the center of the track view display area Ar, but the block Bra and the time line L2 are highlighted, and the block Bra is painted as the reproduction progresses. The crushing progresses, and a playing icon Ic indicating that it is being played is dynamically displayed near the block Bra by, for example, rotation, blinking, color / lightness, and the like. The screen being played is called a “playback screen”. In the “playback screen”, other display contents of the track view display area Ar are not updated with the passage of time, and the file display block Bra being played back is not updated. Still as background.

  In addition, when the user performs a drag operation such as, for example, touching the touch panel with a user's finger or stylus pen and then rubbing (scratching) the screen from the position, the drag operation is performed on the screen. If the position where the drag operation is detected and the track view display area Ar is detected, the current view is scrolled according to the drag operation. For example, when a drag operation is performed in the lower left direction on the “daily view screen”, each track display (track view) is shifted to the left as a whole, and the dates corresponding to the track positions are sequentially traced back in the upper direction. In addition, the display of each part such as the time notation Tc and the time display tag Tg is also updated. That is, on the designated date view screen illustrated in FIG. 4A, the time display at the center of the view display area Ar is sequentially changed to 13:00, 13:30, 14:00, in response to a drag operation in the lower left direction. .., And the middle track is sequentially shifted to 2006/12/10, 2006/12/9, 2006/12/8,.

  If the current view crosses dates as a result of a drag operation on the "Today's view screen" and "Specified date view screen" or automatic scrolling on the "Today's view screen", the status of multiple dates in one track Is displayed continuously. For example, when the view center position of the middle track is about 0:30 by dragging in the left direction with respect to the “designated date view screen” in FIG. 4A, the upper track is about 12:30 on December 9th. 12/10 1:30, the middle track is 12/10 23:30 to 12/11 1:30, and the lower track is 12/11 23:30 to 12/12 The state of the corresponding performance recording file Df is displayed around 1:30. However, when the “daily view screen” at the time of the drag operation is the “filter view screen”, each track displays information from 0:00 to 24:00 on a specific date, and a plurality of tracks are displayed on one track. The date status is not displayed continuously.

  Note that the amount of movement of the screen according to the drag operation may be set separately. When setting the drag control in this way, the screen movement amount per unit operation is increased when the speed of the drag operation is fast, and conversely when the speed of the drag operation is slow, the screen movement per unit operation is increased. The amount may be set to be small.

  When the calendar button B1 is touched on the “daily view screen”, the screen shifts to the “monthly view screen”. In the “monthly view screen”, the calendar of the month including the date corresponding to the date and time set at the center of the track view display area Ar in the “daily view screen” is displayed as shown in FIG. It is displayed in the display area (view display area) Ar. Each date display area of the calendar is changed in display mode such as gradation, hue, and pattern according to the presence / absence of the performance recording file Df and the total recording time of the day. For example, when the file is not recorded, the background display color of the date is white, and for the day when the performance recording file Df is recorded, the display color is grayscale, which increases the recording time of the performance recording file Df. Accordingly, the gradation of the display color is controlled stepwise or continuously so that black becomes darker. If the performance recording file Df is being played when the “monthly view screen” is displayed, a playing icon Ic is displayed on the date including the playing record file Df being played.

  In the upper part of the “monthly view screen”, switching buttons Ba to Bd are juxtaposed to the left and right of the calendar year (“December 2006”), and the calendar is displayed with these buttons Ba to Bd. Can be switched. For example, the previous month or next year (next year) switch button ("<<", ">>") Ba, Bd switches to the "monthly view screen" of the same month of the previous year or next year (next year), and the previous month or next month (next month) ) Switching buttons (“<”, “>”) Bb, Bc are used to switch to the “monthly view screen” of the previous month or the next month (next month).

  The main display area Ar of the “monthly view screen” is called a calendar view display area, and a touch operation on date display in the calendar view display area can be detected by the touch panel. In other words, the date display area functions as a date designation button that, when touched, switches to the “designated date view screen” on the date designated by the date display in the year and month represented by the year and month notation. The functions of the operation buttons B2 to B4 are the same as those of the “daily view screen”, and can be switched to the “today's view screen” by touching the today button B4, for example.

[Search processing]
In the performance recording system according to the embodiment of the present invention, the performance recording file recorded on the recording medium can be retrieved by performing a retrieval process using the “daily view screen” or the “search screen” according to the performance recording program. . The “daily view screen” initially appears on the “today's view screen”, and displays the recording state most recently at the current time in the current view. That is, when no search process is executed, the current time measured by the timer 11 becomes current. When the file display block Br indicating the performance data (performance recording file) Df to be reproduced is on the current view, the desired performance data Df can be specified by touching the block Br. If there is no file display block Br, (1) search for a performance data file Df of a desired date or time by dragging on the “daily view screen” as described above, or (2) a search button After switching to the “search screen” by the operation of B3, the search condition is specified, and the desired performance data file Df is searched by the “filter view screen”.

For the method (2), the time corresponding to the performance information to be reproduced is designated using the “search screen”. As shown in FIG. 5 (1), the “search screen” has a notation of this screen: “search” displayed at the top, and a “return” button B5 and a “execute search” button B6 at the bottom. Is displayed. In the main display area located in the middle of these, a mark designation area (mark selection area) Ra and a search condition input area (search condition designation area) Rb are provided on the left side, and an answer column Rc is provided on the right side. The user inputs a value in the search condition input area Rb or selectively selects mark information in the mark designation area Ra by a method such as designating a place or input character by a touch operation or key operation of the input operation unit 15. The search condition can be specified by instructing to.

  That is, the year, month, day, day of the week, and time can be entered by inputting the time condition in any input field of the year, month, day, day of the week, and time zone (start time and / or end time) in the search condition input area Rb. Time designation information that designates at least one of a band, a start time, and an end time can be generated, stored in a search condition designation field on the RAM 12, and designated as a search condition. For example, a search condition is specified by a date value such as December 11, 2006, 2006, or December, or a search condition is specified by a time value such as 12:12. Alternatively, desired mark information [for example, mark name (for example, mark name ( Nm) = “Christmas”] is selectively designated, the time designation value (Tr) based on the designated mark information is stored in the search condition designation field (further expanded in the search condition input area Rb), and this value is used as the search condition. specify.

  When the search execution button B6 is operated after specifying the search conditions, the search function unit E executes a search process, and the performance data (performance recording file) Df including the specified time specified by the search conditions in the time information T1 to Tn. Is searched, and the search result is displayed in the answer column Rc. Here, when there is performance data Df corresponding to the search condition, the performance data Df is presented to the user as a search result. In this case, the search result display button B7 is displayed in the answer column Rc, and by operating the search result display button B7, the “filter view screen” of FIG. 5 (2) showing the performance data Df as a file display block Br. Is displayed. Then, by performing a touch operation on a desired file display block Br, it is possible to specify performance data Df to be reproduced.

  As a result of the search process, if performance data corresponding to the specified time specified by the search condition is not recorded, a predetermined time range (for example, 1 to several years before or after the specified year unit, monthly unit) 1 to several months before and after the specified date, 1 to several days before and after the specified date, and 1 to several hours before and after the specified time unit) The performance data having the time information T1 to Tn nearest to is additionally searched, and the searched performance data Df is adopted as performance data to be reproduced and presented to the user as a search result. If performance data corresponding to the specified time cannot be obtained even in the additional search, a message that there is no corresponding performance data is displayed in the answer column Rc, and then the screen automatically returns to the “today's view screen”.

  When the performance data Df corresponding to the search condition is obtained by the search processing, the “filter view screen” displays a file display block indicating the performance data Df that matches the specified search condition, as shown in FIG. The filter is applied so that only the Br track is displayed. For example, when a search is performed by specifying “December”, only tracks recorded in December of each year are displayed, and other tracks are not displayed. Note that, for the “filter view screen” displayed according to the search result, the search process can be performed by moving the current view in the same manner as the method (1). It should be noted that after the search process is completed or after a predetermined time (for example, 10 seconds) has elapsed since the reproduction process is completed, the screen may automatically return to the “today's view screen”.

[Setting process]
In the performance recording system according to one embodiment of the present invention, setting processing is performed at an arbitrary time according to a performance recording program, and the user uses a “setting screen” (also referred to as “mark setting screen”) with a name called “mark”. Search conditions can be set. The “setting screen” is displayed by operating the setting button B2 on the “daily view screen” or the “monthly view screen”. In this “setting screen”, as illustrated in FIG. 6, current time notation, screen name notation: “mark setting” and “return” button B 5 are displayed at the top, and a mark list is displayed in the main part at the bottom. A display area Rd is provided on the left side, and a mark name input area (mark setting area) Re and a date / time input area (search condition setting area) Rf are provided on the left side. In addition, “add”, “modify”, and “delete” buttons B8 to B10 are provided side by side below the date / time input area Rf.

  In order to newly set a mark, a desired mark name (for example, “Christmas”) is displayed in the mark name input area (mark name setting field) Re as shown in the figure by touch operation or key operation of the input operation unit 15. In the date / time input area (search condition setting field) Rf in any input column of year, month, day, day of the week, and time zone (start time and / or end time) [for example, “every year” (It may or may not be input), “12” month, “25” day] is input, and then the add button B8 is operated. The user can set a “mark” at any time (period). Thereby, the mark information Mr including the mark name information Nm representing the input mark name and the time specifying information Tr specifying the input time condition is set on the RAM 12, and the set mark information Mr is stored in the external storage device 14. Can be registered in the mark storage area.

  FIG. 7 shows a setting example of the mark information Mr. In this example, the mark information Mr of mark name Nm = “lunch break” in (1) is the performance data Df recorded from 12:00 to 13:00 regardless of the year, month and day according to the time designation information Tr. Instructs what to search for. The mark information Mr of mark name Nm = “birthday” in (2) indicates that the performance data Df recorded on July 7 every year should be searched by the time designation information Tr, (3) The mark information Mr of the mark name Nm = “Lesson” indicates that the performance data Df recorded from 16:00 to 17:00 every Friday (FRI) time should be searched by the time designation information Tr. . Then, the mark information Mr of mark name Nm = “Christmas” in (4) indicates that the performance data Df recorded on December 25 every year should be searched by the time designation information Tr.

  When correcting an already set mark, the mark name of the set mark information displayed in the mark list display area Rd (for example, “marriage anniversary”, “lunch break”, “birthday”) by the user's mark selection operation "," Lesson "," Christmas "), the mark name to be reset is selectively instructed, and the setting contents are expanded in both input areas Re and Rf. By the value input operation, the mark name Nm or time designation Tr to be corrected Is changed, and the mark name Nm or the time designation Tr of the mark information is corrected by operating the correction button B9. Further, when deleting the set mark, the name of the mark to be deleted is selected from the set mark names in the mark list display area Rd by the user operation, and after confirming the setting contents in the display of both fields Re and Rf When the delete button B10 is operated, the mark information is deleted from the registered mark information group.

[Reproduction processing]
In the performance recording system according to the embodiment of the present invention, when there is a touch operation on the file display block Br displayed on the “daily view screen”, a predetermined operation by the timer 11 called “timer 2 interrupt” is performed according to the performance recording program. Reproduction processing is executed by interruption every time. That is, when a desired file display block Br in the “today's view screen”, “designated date view screen” or “filter view screen” is touch-operated, a display is made such that the top position of the block Br is positioned at the center of the screen. The content is updated (scrolled), and playback is started. In this case, as shown in FIG. 4 (1), a playing icon Ic is displayed in the playing file display block Bra representing the playing performance data (playing record file) Df being played, and according to the playing status (progress). The display mode is updated in a progress bar by processing such as painting (color painting) the block Bra. At this time, when switching to the “monthly view screen” by operating the calendar button B1, as shown in FIG. 4 (2), it corresponds to the date (“11”) when the performance data Df being reproduced is recorded. A playing icon Ic is displayed in the date display area.

  When the file display block Bra being reproduced is touched, the reproduction of the performance data Df indicated by the block Bra is stopped, and the display content in the track view display area Ar holds the current state. When the block Bra is touched again, the reproduction of the performance data Df is resumed from the position where it was stopped. Note that the reproduction may be completely stopped when the file display block Bra being reproduced is touched. In this case, the display of the track view display area Ar is returned to the state immediately before the reproduction, and the display mode of the block Bra is also returned to the state before the reproduction (the same as the block Br in FIG. 4A).

[Example of processing flow]
In the performance recording system according to the embodiment of the present invention, the performance recording process is executed according to the performance recording program. 8 to 11 are flowcharts showing examples of performance recording processing according to one embodiment of the present invention. FIGS. 8 and 9 show main processing, FIG. 10 shows monitoring task processing, and FIG. 11 shows reproduction processing. Indicates. When the power switch of the input operation unit 15 is turned on (ON) by a user operation, the main processing of FIGS. 8 and 9 is started, and the CPU 10 first activates the monitoring task in step P1, and thereafter the timer 1 interrupt. The monitoring task process shown in FIG. 10 is executed at predetermined time intervals.

  In the next step P2, the file information Fd registered in the performance recording database of the external storage device 14 is read, and data necessary for displaying the file display block Br in the track view display area Ar is acquired. Next, in step P3, the real time RealTime is set to True, and the current view can be updated (scrolled) according to the passage of time. At the next step P4, “today's view screen” is displayed on the display 19a. Then, the panel operation is awaited in the next step P5. The “today's view screen” displayed in step P4 is scrolled sequentially to the left in the screen according to the time of the timer 11 by monitoring task processing described later.

  In Step P5, it is detected whether or not the panel operation, that is, the operation of the panel operator of the input operation unit 15 has been performed. When there is a panel operation other than the power off (OFF) instruction, the process proceeds to Step P6. Sometimes, it is determined whether the screen displayed on the display 19a is a “daily view screen”, a “monthly view screen”, a “setting screen”, or a “search screen”.

  Here, when it is determined that the “daily view screen” is displayed (P6 = 1 day view), the process proceeds to step P7 to determine whether or not the operation detected in step P5 is a drag. When it is a drag (P7 = YES), in step P8, the current view of the “daily view screen” is scrolled according to the drag operation, and in the next step P9, the real-time RealTime flag is set to True (true). If so, set this to False. In other words, if it is “today's view screen”, the screen shifts to “designated date view screen”. Then, the process returns to step P5 and waits for the next panel operation. The real time flag is used to determine whether or not the current is the current time. When the current is the current time (RealTime = True), the “today's view screen” is displayed. If not (RealTime = False), a “designated date view screen” is displayed.

  On the other hand, when it is determined in step P7 that it is not a drag on the “daily view screen” (P7 = NO) or when it is determined in step P6 that it is a “monthly view screen” (P6 = 1 day view), Proceeding to step P10, it is determined whether or not the detected operation is a touch on the calendar, setting, search, or the today buttons B1 to B4 or the date designation button. Here, when the button B1 to B4 or the date designation button is touched (P10 = YES), in step P11, “monthly view screen”, “setting screen”, “search” corresponding to the touch-operated button. The screen is switched to “screen”, “today's view screen”, or “designated date view screen” with the date specified, and the process returns to step P5 to wait for the next panel operation.

  If it is determined in step P10 that the detected operation is not a button touch (P10 = NO), it is determined in step P12 whether the operation is a touch on the file display block Br. Here, when the operation is a touch operation on the block Br (P12 = YES), the reproduction of the performance recording file DF corresponding to the touched block Br is started or stopped in Step P13, and the next operation is performed accordingly. The screen is updated in step S14. Then, after the process of step S14 or after determining that the operation is not a block touch but another operation in step P12 (P12 = NO) and performing another process corresponding to the other operation, the process returns to step P5 and continues. Wait for the panel operation. Other processing includes setting processing other than “mark setting” (for example, setting of the current time, setting of drag control, setting of display scale in the one-day view, etc.) and export of the recorded file Df ( For example, the file name is changed, the file is saved on a different medium, and the like. These processes are executed according to an operation of a predetermined operator (not shown) of the input operation unit 15, and are described later in steps P21 and P29. Even when it is determined that it is another operation (P21, P29 = NO), it can be executed.

  In steps P13 and S14, for example, if it is the first block touch operation, the playback process by the timer 2 interrupt shown in FIG. 11 is started, and the performance recording file DF corresponding to the touched file display block Br is activated. The reproduction of the block Br is started by switching to the reproduction screen, and thereafter, the reproduction process is executed at predetermined time intervals until the next touch on the block Br. In this case, if the real time RealTime = True (true) at the time of switching to the playback screen, the real time RealTime is set to False (false), and the time scroll of the current view is stopped. When the same block Br is continuously touched (no touches on other blocks are present), the performance recording file DF corresponding to the block Br in response to the even (2, 4,...) Touch. The playback process of the file DF is restarted in response to the odd (3, 5,...) Touch. If another block is touched during playback of a performance recording file corresponding to a certain block, this playback is terminated and playback of the performance recording file corresponding to the other block is started.

  When it is determined in step P6 that it is a “setting screen” (P6 = setting), the process proceeds to step P15 in FIG. 9 (1) showing setting processing using the setting screen, and the detected operation is set on the setting screen [FIG. It is detected whether or not the value is input to the mark name and date / time input areas Re and Rf. Here, when the value is input to the input areas Re and Rf, in step P16, the input value is stored in the corresponding mark name and search condition setting fields in the RAM 12, and set (set) as mark information Mr. At the same time, the display of the input areas Re and Rf is updated with the input value. And it returns to step P5 (FIG. 8) and waits for the next panel operation.

  On the other hand, when it is determined in step P15 that the value is not input to the input areas Re and Rf (P15 = NO), it is determined in step P17 whether or not the detected operation is a mark selection for the mark list display area Rd. judge. Here, when the mark selection operation is for the list display area Rd (P17 = YES), first, in step P18, mark information Mr corresponding to the mark selection operation, that is, a predetermined condition is set in the mark storage area of the external storage device 14. Then, the process proceeds to step P16, where the mark name information Nm and the time designation information Tr of the mark information Mr are stored in the corresponding setting fields and displayed in the input areas Re and Rf.

  If it is determined in step P17 that the operation is not a mark selection operation (P17 = NO), it is determined in step P19 whether or not the detected operation is a touch on any of the add, modify, and delete buttons B8 to B10. To do. Here, when the touch is on the buttons B8 to B10 (P19 = YES), the process proceeds to Step P20 and the definition of the mark information Mr (in the input areas Re and Rf) according to the type of the operated buttons B8 to B10. (Input or display) is updated, and the updated contents are stored in the mark storage area (14). For example, in the case of an operation for adding or correcting the mark information Mr, the mark information Mr is added or corrected with the value set (set) in step P16, and in the case of a deleting operation, the mark information from the mark storage area (14). Delete Mr. When mark information is added or deleted or the mark name is changed, the mark name display in the mark list display area Rd is updated. Then, the process returns to step P5 and waits for the next panel operation.

  If it is determined in step P19 that the detected operation is not a touch on the buttons B8 to B10 (P19 = NO), it is determined in step P21 whether or not the operation is a touch on the “return” button B5. When the touch operation is performed on the “return” button B5 (P21 = YES), the process proceeds to step P22, and the display circuit 16 is restored so that the screen display on the display 19a returns to the screen immediately before the transition to the setting screen. Instruct. After the process of step S22 or after determining that the operation is not a touch to the “return” button B5 in step P21 (P21 = NO) and performing other processes corresponding to the other operations. Returning to Step P5, the next panel operation is awaited.

  When it is determined in step P6 that it is the “search screen” (P6 = search), the process proceeds to step P23 in FIG. 9 (2) showing the setting process using the setting screen [see FIG. 5 (1)] and detected. It is detected whether the selected operation is an instruction of mark information in the mark designation area Ra of the setting screen or a value input to the search condition designation area Rb. If it is a mark instruction or value input operation, the value indicated by the time designation information Tr of the designated mark information Mr or the inputted value is stored in the corresponding search condition designation field in the RAM 12 in step P24. The search condition is set (designated) and the display of the search condition input area Rb is updated with the input value. And it returns to step P5 (FIG. 8) and waits for the next panel operation.

  On the other hand, when it is determined in step P23 that it is not a mark instruction or value input operation (P23 = NO), it is determined in step P25 whether or not the detected operation is a touch on the search execution button B6. If the search execution button B6 is a touch operation (P25 = YES), the process proceeds to step P26, the database (14) is searched according to the search conditions set (designated) in step P24, and in the next step P27. Determine the search results. If there is a performance recording file Df corresponding to the search condition as a result of the determination of the search result (P27 = relevant), the number of performance recording files Df corresponding to the search condition is displayed in the answer column Rc in step P28. The search result display button B7 is displayed, and then the process returns to step P5 to wait for the next panel operation. On the other hand, when there is no performance recording file that satisfies the search condition (P27 = not applicable), a message to that effect is displayed in the answer column Rc, and the process returns to step P5.

  If it is determined in step P25 that the detected operation is not a touch on the search execution button B6 (P25 = NO), it is determined in step P29 whether the touch is a touch on the “return” button B5. When the touch operation is performed on the “return” button B5 (P29 = YES), the process proceeds to step P30, and the display circuit 16 is set so that the screen display on the display 19a is restored to the screen immediately before the transition to the setting screen. Instruct. Then, after the processing in step S30, or in step P29, it is determined that the operation is not a touch on the “return” button B5 (P29 = NO), and other processing corresponding to the other operation (search result) (Including the process of shifting to the “filter view screen” according to the operation of the display button B7), the process returns to step P5 (FIG. 8) and waits for the next panel operation.

  If there is a panel operation instructed to turn off the power in step P5, the process proceeds to step P31. In step P31, when the result file information Fd of the monitoring task process (FIG. 10) described later is created, the file information Fd held in the file information storage area on the RAM 12 is saved in the database (14), and the database information is stored. After updating and performing necessary end processing, the power is automatically turned off to end the main processing. If the file information is not created in the monitoring task process, the main process is immediately terminated after performing the necessary termination process in step P31.

  FIG. 10 shows a processing flow by the monitoring task. When the monitoring task process starts from the timer 1 interrupt, the CPU 10 first determines in step Q1 whether or not a performance event Di has been input based on the operation of the performance operator (2a), and the performance event Di has been input. If the sound source unit 2a is provided in the apparatus as in the system configuration example of FIG. 2 (Q1 = YES), a performance event is sent to the sound source (2b) in step Q2. In the case where the sound source unit 2a is provided in another device on the performance operator side as in the system configuration example of FIG. 1, the performance event Di is input to the sound source (2b) in the other device simultaneously with the input of the performance event Di. Is sent out. In the next step Q3, the time at which the performance event Di is input is detected, the time information Tm representing the detected time and the performance event Di are paired, and the buffer area of the RAM 12 in the format of “time Tm + performance event Di”. [See FIG. 3 (1)].

  Next, in step Q4, it is checked whether the setting state of the real time RealTime is True (false) or False (false). If true (Q4 = True), the timer is set in step Q5. The current view of “Today's view screen” is scrolled by time according to the time of 11, and the display is updated. After the current view display update in step Q5, or when it is determined in step Q4 that the real time RealTime is False (false) (Q4 = False), the process proceeds to step Q6, and a predetermined time (for example, 10 seconds), It is determined whether or not the panel operator of the input operation unit 15 is not operated and a screen other than the “today's view screen” is being displayed. Here, if the panel operator is operated within a predetermined time or the “today's view screen” is displayed (Q6 = NO), the current timer 1 interrupt is terminated as it is.

  On the other hand, when it is determined in step Q6 that a screen other than the “today's view screen” is displayed without any panel operation for a predetermined time (Q6 = YES), the screen display is changed to “today's view”. After switching to “screen” and setting the real time RealTime to True in step Q8, the current timer 1 interrupt is terminated.

  When the monitoring task process is started by the current timer 1 interrupt, if it is determined in step Q1 that there is no performance event input (Q1 = NO), the process proceeds to step Q9, and the time area is set in the buffer area of the RAM 12. It is determined whether or not performance information in the format of “Tm + performance event Di” is held. If not held (Q9 = NO), the process proceeds to step Q4, and the processes of steps Q4 to Q8 described above are performed.

  On the other hand, when it is determined in step Q9 that performance information in the format of “time + performance event” is held (Q9 = YES), the time when the performance event was last input in step Q10, That is, it is determined whether or not a predetermined time (for example, 10 seconds) has elapsed since the latest (last) time of the performance information in the format of “time Tm + performance event Di” held in the buffer area. If not (Q10 = NO), the process proceeds to step Q4, and the processes of steps Q4 to Q8 described above are performed.

  On the other hand, when it is determined in step Q10 that a predetermined time has elapsed since the last performance event input time (Q10 = YES), the process proceeds to step Q11, and a series of “time Tm + performance event Di” format held in the buffer area. Is reconstructed into a file format to create a performance recording file Df (see FIG. 3B). In step Q11, the first time Tm = start time information T1 of the performance information in the format of “time Tm + performance event Di” = start time information T1, latest time Tm = end time information Tn, and file designation information (file name information). File information Fd is created [see FIG. 3 (3)] and stored in the file information storage area on the RAM 12. In the next step Q12, the created performance recording file Df is stored in the storage (14). At this stage, as indicated by a broken line, in step Q13, the file information Fd created in step Q11 may be saved in the database (14) and the database may be updated. The database update process in step P31 (FIG. 8) of the process is omitted. After step Q12 or step Q12, the process proceeds to step Q4, and the above-described steps Q4 to Q8 are performed.

  FIG. 11 shows a reproduction processing flow. When the reproduction process by the timer 2 interrupt is started in response to the file reproduction start instruction in step P13 (FIG. 8) of the main process, the CPU 10 performs the performance recording file Df corresponding to the touch-operated file display block Bra [FIG. 3 (2)]. The performance events D1, D2,..., Dn of the performance recording file DF are sequentially read from the top in accordance with the current time measured by the timer 11 with reference to the timing information Δt. That is, in step R1, it is determined whether or not there is a next performance event (a performance event corresponding to the timing after the current time). If there is a next performance event (R1 = YES), then in step R2, it is further performed. Then, it is determined whether or not the current time is the reproduction timing of the next performance event. If it is not the playback timing of the next performance event (R2 = NO), the current timer 2 interrupt is immediately terminated.

  On the other hand, when the current time is the playback timing of the next performance event (R2 = YES), the next performance event is read at step R3, and the read event is read at step R4 as a sound source (2b: 3b in FIG. 2). : In the case of FIG. 1, and further, in step R4, the display mode of the file display block Bra corresponding to the performance recording file DF is updated (for example, painting progresses). Then, the current timer 2 interrupt is terminated.

  Further, when the performance event is played back and it is determined in step R1 that there is no next performance event (R1 = NO), a process for stopping the timer 2 interrupt is performed in step R6, and then the response is performed in step R4. The display of the block Bra is updated and the timer 2 interrupt is terminated.

[Various Embodiments]
Although a preferred embodiment of the present invention has been described above, this is merely an example, and the present invention can be variously modified and implemented in various modes without departing from the spirit of the invention. Can do. For example, when a “play / stop” button is displayed and this button is touched, the performance information temporarily stored (unsaved as a file) may be played back.

In the embodiment, when the “monthly view screen” is displayed, the display color is controlled to be dark according to the file recording time for each date, but the present invention is not limited to this. For example,
(1) The color may be changed. For example, the hue of the display color may be controlled from a cold color to a warm color (eg, blue → yellow → red) according to the file recording time.
(2) An icon corresponding to the file recording time may be displayed. For example, an icon such as a flower circle is displayed on a long recording day.
(3) A recording time graph may be displayed corresponding to each date.
(4) Any mode may be used as long as the recording time in the file can be determined for each date displayed on the calendar.

With regard to the current view of the “daily view screen”, several hours of the previous and subsequent days (upper and lower tracks) are displayed on one screen based on the date and time (center), but this is not restrictive. For example,
(1) The horizontal scale may be arbitrarily set within a range of several minutes to 24 hours by a user operation.
(2) The number of tracks may be increased, and information about 1 day to several days (7 days) may be displayed at a time.

  Even when the performance recording file (Df) is being reproduced (during execution of the reproduction process), the performance information (Di) input to the performance input unit (A) by the monitoring task process is sequentially recorded. The performance information is also input to the performance input unit (A) as performance information (Di '), and when the performance information (Di) is input from the performance operation unit (2a), the performance information (Di) You may comprise so that what mixed the performance information (Di ') during reproduction | regeneration may be recorded. In this case, the performance information (Di ′) being reproduced and the input performance information (Di) are made to be different MIDI channels, or recorded in two different files corresponding to the same time, and either one is reproduced. It may be configured to be reproducible only by itself.

  On the contrary, when the performance recording file Df is being reproduced (during execution of the reproduction process), the monitoring task process may be temporarily stopped to reduce the processing load.

  In the embodiment, the input and recording of performance information (performance operation information) has been described. However, in addition to performance information, one or more types of information may be recorded simultaneously as input and recording target information. . For example, in addition to the performance operating device (2) and the sound source device (3), a microphone and a camera are connected to the communication I / F (17) and input from the performance input means (A), voice input means or image input means. Performance information, microphone sound, or camera-captured images may be recorded simultaneously. In this case, it is preferable to reproduce each information in synchronism during reproduction.

  For example, audio information is input at the same time as performance information is input, the input audio level is monitored in the same way as performance information, and input start / end is detected depending on whether the input level is a predetermined value or more. The voice information input from the start to the end of input is temporarily held in the buffer. When both the performance information and the sound information are kept in the non-input state for a predetermined time (about 10 seconds), the performance information and the sound information stored in the buffer are reconstructed and stored in continuous data files. . Note that image information is processed in the same manner by monitoring the presence or absence of “movement” in the shooting frame using an infrared sensor or image processing, and detecting the start / end of input according to the presence or absence of “movement”. Can do.
