  According to the present invention, it is possible to perform various repeated reproductions of automatic performance data.

  FIG. 1 is a block diagram showing a hardware configuration of an automatic performance apparatus 1 as an electronic information processing apparatus according to an embodiment of the present invention.

  The automatic performance device 1 is a device capable of performing reproduction processing of automatic performance data such as an electronic musical instrument having a performance operator such as a keyboard, a sound source device, and a reproduction device.

  A RAM 7, ROM 8, CPU 9, timer 10, detection circuit 11, display circuit 13, storage device 15, sound source / effect circuit 18, and communication interface (I / F) 21 are connected to the bus 6 of the automatic performance device 1.

  The RAM 7 has a buffer area such as a reproduction buffer, a working area of the CPU 9 that stores flags, registers, various parameters, and the like.

  The ROM 8 can store various data files, various parameters and a control program, or a program for realizing the present embodiment. In this case, it is not necessary to store programs or the like in the storage device 15 in an overlapping manner.

  The CPU 9 controls the arithmetic or automatic performance device 1 according to a control program stored in the ROM 8 or the storage device 15 or a program for realizing the present embodiment. The timer 10 is connected to the CPU 9 and supplies a basic clock signal, interrupt processing timing, and the like to the CPU 9.

  The user can perform various inputs, settings, and selections using the setting operator 12 connected to the detection circuit 11. For example, the setting operator 12 may be any switch, pad, fader, slider, rotary encoder, joystick, jog shuttle, character input keyboard, mouse, or the like that can output a signal in accordance with the user input. . The setting operator 12 may be a soft switch or the like displayed on the display device 14 that is operated using another operator such as a cursor switch. In the present embodiment, a phrase repeat switch and an AB repeat switch (A point designation switch, B point designation switch) to be described later are prepared as the setting operator 12.

  The display circuit 13 is connected to the display device 14 and can display various information on the display device 14. The user refers to the information displayed on the display device 14 and performs various inputs and settings.

  The storage device 15 is a combination of a storage medium such as a hard disk, an FD (flexible disk or floppy disk (registered trademark)), a CD (compact disk), a DVD (digital multipurpose disk), or a semiconductor memory such as a flash memory, and a driving device thereof. It is composed of at least one. The storage medium may be detachable or may be built in the automatic performance device 1. The storage device 15 and / or the ROM 8 may store automatic performance data (FIG. 2), a program for realizing each embodiment of the present invention, and other programs for controlling the automatic performance device 1. it can. In the case where a program for realizing each embodiment of the present invention and other programs for controlling the automatic performance device 1 are stored in the storage device 15, it is not necessary to store them together with the ROM 8. Alternatively, only some programs may be stored in the storage device 15 and other programs may be stored in the ROM 8.

  The sound source / effect circuit 18 includes automatic performance data PD (FIG. 2) recorded in the storage device 15, ROM 8, RAM 7, or the like, performance signals supplied from the performance operator 22 or an external device connected to the communication interface 21, A musical tone signal is generated in accordance with a MIDI signal or the like, and various musical effects are given to the sound system 19. The sound system 19 includes a D / A converter and a speaker, converts a digital musical tone signal supplied to an analog format and generates a sound.

  A performance operator (keyboard, pad, etc.) 22 is an operator for inputting a user's performance, and has a pitch corresponding to the operator operated by the user, and an operation start timing and an end timing for the user's operator. Are input as key-on and key-off signals, respectively.

  The communication interface 21 is a music-only wired I / F such as MIDI, a general-purpose short-distance wired I / F such as USB or IEEE1394, a general-purpose network I / F such as Ethernet (registered trademark), a wireless LAN, Bluetooth (registered trademark), or the like. And at least one communication interface such as a general-purpose short-range wireless I / F.

  FIG. 2 is a conceptual diagram showing the configuration of the automatic performance data PD according to the embodiment of the present invention.

  The automatic performance data PD is data for automatic performance such as MIDI data, and includes a header HD, timing data TD, and various events EV reproduced at the timing indicated by the timing data.

  The automatic performance data PD is stored in, for example, the external storage device 15 or the ROM 8 in FIG. Further, the automatic performance data PD is not limited to the data stored in the automatic performance device 1 but may be acquired via the communication network 3. For example, the data may be downloaded from a performance data distribution service on a network such as the Internet by pseudo streaming (downloading method in which MIDI data or the like is downloaded at once and automatically deleted after the reproduction is finished). The automatic performance data PD is stored in the external storage device 15 of FIG. 1 and is stored in a reproduction buffer such as the RAM 7 during reproduction. The automatic performance data PD temporarily downloaded by pseudo streaming or the like is stored in a reproduction buffer such as the RAM 7 and is erased after the reproduction is completed.

  The header HD is a part for describing the automatic performance data PD. For example, when the automatic performance data PD is a standard MIDI file (SMF), the format (0/1/2) and the division (note resolution) are used. Etc. are described. The performance data PD may be other than the standard MIDI file, and in this case, other information is stored. The header HD is normally arranged at the head portion of the automatic performance data PD, and the actual data is described thereafter. The entity data is, for example, a combination of timing data TD and event EV arranged in time series.

  The timing data TD is data represented by Tick (also referred to as Clock) obtained by dividing a predetermined note length by a predetermined number (resolution). As an example, it is assumed that a quarter note is divided by 1920. In this case, “resolution = 1920” is used, and 1920 Tick corresponds to the length of one quarter note. Since Tick is a quarter note divided by resolution, the time length of Tick varies depending on the tempo. The timing data TD may be expressed by an absolute timing (number of ticks) from a predetermined position such as the head of the music (performance data PD), or a relative timing (number of ticks) from the previous event (timing data TD). It may be expressed as In this embodiment, the timing data TD is expressed by absolute timing from the beginning of the performance data PD.

  The event EV is data to be reproduced (output to the tone generator circuit 18 or the effect circuit 19 in FIG. 1) or read out at the timing indicated by the timing data TD. For example, the event EV is a note event, a program change that changes a tone, a volume, Control changes (all notes off, all sounds off, etc.) that change effects, system exclusives, bar lines (events corresponding to bar lines ML in FIGS. 3 to 5), phrase marks (phrase marks in FIGS. 3 to 5) Event corresponding to the PHM). Note that the note event may be different from note-on and note-off, or may be a combination of note-on and gate time. In this embodiment, it is assumed that note events are recorded by a combination of note-on and gate time. An end event is recorded at the end of the automatic performance data PD.

  The bar line ML is an event inserted at a break position of each bar, and is described by, for example, a text meta event. Note that the event representing the bar line ML is not essential. For example, the position of the bar line ML may be identified by integrating the timing data TD.

  The phrase mark PHM is an event inserted at a musical phrase delimiter position, and can be inserted independently of the bar line position. It is also possible to match the position of the bar line. The phrase mark PHM may represent only the phrase separation position or may be described together with the phrase number. The phrase mark PHM is described by a text meta event, for example.

  Next, the repeat function according to the embodiment of the present invention will be described. In the embodiment of the present invention, a repeat function is realized by combining AB repeat and phrase repeat.

  In this embodiment, as the repeat mode, “phrase repeat mode (including standby)”, “AB repeat mode (including standby)”, “AB phrase repeat mode (including standby)”, “repeat” "Off" is prepared.

  3 to 7 are conceptual diagrams for explaining a repeat function in each repeat mode according to the embodiment of the present invention. In each figure, bar line ML (ML1-16) represents the break position of each bar from 1 to 16 bars, and phrase marks PHM1 to PHM3 represent the break positions between phrases 1 to 4. In addition, a solid line arrow in the horizontal direction represents a playback section of the automatic performance data PD, and a vertical arrow represents an operation timing position of each operation by the user.

  FIG. 3 is a conceptual diagram for explaining an example of a repeat function in the phrase repeat mode according to the embodiment of the present invention.

  The “phrase repeat mode” is a mode in which a specified phrase (a phrase that is played when the phrase repeat switch is operated) is repeatedly played from the beginning to the end.

  In the example shown in FIG. 3, when the user operates the phrase repeat switch (setting operator 12) during normal playback of automatic performance data PD (when repeat playback is not being performed), the repeat mode is set to the phrase repeat mode, The reproduction of the automatic performance data PD immediately returns to the beginning position of the phrase being reproduced when the operation is performed, and repeatedly reproduces the phrase from the beginning to the end. In this example, after passing the phrase mark PHM1, the user operates the phrase repeat switch (setting operation element 12) at the point of time when the vertical arrow in the figure is ON. After that, the phrase 2 is repeatedly reproduced from the beginning to the end.

  In the “phrase repeat mode”, when the phrase repeat switch (setting operation element 12) is operated again without operating the AB repeat switch (point A and point B designation switch), the repeat mode is set to repeat off, Return to normal playback (playback without repeat playback). When the first phrase repeat switch is operated, instead of immediately returning to the beginning of the phrase, the end of the measure being played (4th measure in this example) or the phrase (phrase 2 in this example) After the playback to the end of, it may be possible to return to the head position of the phrase being played back (phrase 2 in this example) at the time when the operation is performed and resume playback from the head position.

  FIG. 4 is a conceptual diagram for explaining an example of a repeat function in the AB repeat mode according to the embodiment of the present invention.

  The “AB repeat mode” is a mode in which playback is repeatedly performed from the start position of a bar including a point A designated by a user operation to the end position of a bar including a B point designated by a user operation.

  During normal playback of automatic performance data PD (when repeat playback is not being performed), when the user operates the A point setting switch (setting operation element 12), the repeat mode is AB repeat mode (B point specification waiting, hereinafter AB repeat). When the user operates the B point setting switch (setting operation element 12), the repeat mode is set to AB repeat mode (AB repeat on) and immediately ( Or after playback to the end position of the bar including the designated B point), the head returns to the start position of the bar including the A point, and thereafter, the bar including the B point is changed from the start position of the bar including the A point. Repeat playback to the end position.

  In the example shown in FIG. 4, the A point is designated after passage of the bar line ML7, that is, during reproduction of the seventh bar, and then the B point is designated after passage of the bar line ML11, ie, during reproduction of the eleventh bar. Therefore, as shown in the figure, immediately after the B point is designated, the head immediately returns to the start position of the seventh measure, and thereafter, the seventh measure to the eleventh measure are repeatedly reproduced. Thereafter, when the AB repeat-off switch is operated, the repeat mode is set to repeat-off, and normal playback (playback without repeat playback) is resumed.

  In the AB repeat switch, the A point designation switch, the B point designation switch, and the AB repeat off switch may be assigned to three independent setting operators 12, respectively, and one setting operator 12 as an AB repeat switch. The first operation may designate an A point, the second operation may designate a B point, and the third operation may be AB repeat off.

  “AB Phrase Repeat Mode” includes “Phrase Repeat Mode” and “Phrase Repeat Mode” when the user designates A point or when the phrase repeat switch is operated in “AB Repeat Mode”. This is a repeat mode in combination with “AB repeat mode”. The “AB phrase repeat mode” will be described in detail below with reference to FIGS.

  In the present embodiment, the AB repeat switch is used to specify the start point and end point of repeat playback in units of bars, and the start and end positions of the bars included in the point are specified as the repeat playback start point and end point. However, when the phrase repeat function is on (phrase repeat mode), the AB repeat function instruction (A point designation and B point designation) is performed on a phrase-by-phrase basis, and the start and end positions of the phrase included in the point are specified. Specify the repeat playback start point and end point.

  FIG. 5 is a conceptual diagram for explaining an example of a repeat function in the AB phrase repeat mode according to the embodiment of the present invention.

  During normal playback of the automatic performance data PD (when repeat playback is not being performed), when the user operates the phrase repeat switch (setting operation element 12), the repeat mode is set to the phrase repeat mode, and the automatic performance data PD is played back. Immediately when the operation is performed, the beginning of the phrase being played back is restored. Thereafter, when the user operates the A point setting switch (setting operation element 12) during the reproduction of the automatic performance data PD in the “phrase repeat mode”, the repeat mode is changed to the AB phrase repeat mode (while waiting for the B point designation, hereinafter the AB phrase). (Referred to as repeat standby mode) and playback is continued. In this case, since the “phrase repeat mode” is once canceled, phrases after the phrase that is played back repeatedly in the “phrase repeat mode” are also played back. When the user operates the B point setting switch (setting operation element 12) during the AB phrase repeat standby mode, the repeat mode is set to the AB phrase repeat mode (AB phrase repeat on) and immediately (or the designated B point) After playback is performed up to the end position of the phrase or measure including), the head returns to the beginning position of the phrase including point A. Thereafter, playback is repeated from the beginning position of the phrase including the point A to the end position of the phrase including the point B. When either the phrase repeat switch or the AB repeat switch is operated again, the repeat mode is set to repeat off, and normal playback (playback without repeat playback) is resumed.

  In the example shown in FIG. 5, during normal playback of automatic performance data PD (when repeat playback is not being performed), after passing through the phrase mark PHM1, the user repeats the phrase repeat switch (setting) when the vertical arrow in the figure is ON. When the operator 12) is operated, the repeat mode is once set to the phrase repeat mode, and the reproduction of the automatic performance data PD immediately returns to the beginning position of the phrase being reproduced at the time when the operation is performed. Playback resumes. The repeat mode is set to the phrase repeat mode, and the subsequent point designation by the A point setting switch designates the phrase unit, that is, designates the head of the phrase including the A point as the A point. After that, after passing bar line ML7, that is, during playback of the seventh bar, the A point is designated, the repeat mode is set to the AB repeat standby mode, and the start position of phrase 2 including the A point is repeated playback. Designated as the starting point (point A). Further, after the passage of the bar line ML11, that is, during the reproduction of the eleventh bar, the AB phrase repeat mode is set by designating the B point, and the phrase 3 including the B point is set to the repeat reproduction end point ( B point) and immediately return to the beginning position of phrase 2, and thereafter, phrase 2 to phrase 3 are repeatedly reproduced.

  FIG. 6 is a conceptual diagram for explaining another example of the repeat function in the AB phrase repeat mode according to the embodiment of the present invention.

  During normal playback of automatic performance data PD (when repeat playback is not being performed), when the user operates the A point setting switch (setting operation element 12), the repeat mode is once set to AB repeat mode (waiting for B point designation). At the same time, the point is designated as point A (repeat reproduction start point), and reproduction is continued. Thereafter, when the user operates the phrase repeat switch (setting operation element 12), the repeat mode is set to the AB phrase repeat standby mode, and further reproduction is continued. After that, when the user operates the B point setting switch (setting operation element 12) during the AB phrase repeat standby mode, the repeat mode is set to the AB phrase repeat mode (AB phrase repeat on) and is immediately (or specified) After playback to the end position of the phrase or measure including point B), it returns to the beginning position of the measure including point A). Thereafter, the playback is repeatedly performed from the beginning position of the bar including point A to the end position of the phrase including point B. When either the phrase repeat switch or the AB repeat switch is operated again, the repeat mode is set to repeat off, and normal playback (playback without repeat playback) is resumed.

  In the example shown in FIG. 6, during normal playback of automatic performance data PD (when repeat playback is not being performed), after the passage of the bar line ML6, that is, during playback of the sixth bar, the user switches the A point setting switch (setting operation). By operating the child 12), the head position of the sixth measure including the A point is designated as the A point. After that, since the user operates the phrase repeat switch (setting operation element 12) at the time of the vertical arrow ON in the figure, the repeat mode is set to the AB phrase repeat standby mode, and the subsequent B point setting switch In the point designation, designation in phrase units, that is, the end of the phrase including the B point is designated as the B point. Therefore, the repeat mode is set to the AB phrase repeat mode after the passage of the bar line ML11 included in the phrase 3, that is, during the reproduction of the phrase 3, and the repeat mode is set to the AB phrase repeat mode. Is designated as point B (repeat playback end point), and immediately returns to the beginning of the sixth measure as shown in the figure, and thereafter, from the sixth measure to the end of phrase 3 is repeatedly reproduced. Thereafter, when the phrase repeat switch or AB repeat off switch is operated, the repeat mode is set to repeat off, and normal playback (playback without repeat playback) is resumed.

  FIG. 7 is a conceptual diagram for explaining still another example of the repeat function in the AB phrase repeat mode according to the embodiment of the present invention.

  During normal playback of the automatic performance data PD (when repeat playback is not being performed), when the user operates the phrase repeat switch (setting operation element 12), the repeat mode is set to the phrase repeat mode, and the automatic performance data PD is played back. Immediately when the operation is performed, the beginning of the phrase being played back is restored. Thereafter, when the user operates the A point setting switch (setting operation element 12) during the reproduction of the automatic performance data PD in the “phrase repeat mode”, the repeat mode is changed to the AB phrase repeat mode (while waiting for the B point designation, hereinafter the AB phrase). (Referred to as repeat standby mode) and playback is continued. In this case, since the “phrase repeat mode” is once canceled, phrases after the phrase that is played back repeatedly in the “phrase repeat mode” are also played back. When the user operates the phrase repeat switch again during the AB phrase repeat standby mode, the repeat mode becomes the AB repeat mode, and the subsequent point designation is in bar units. Therefore, when the user operates the B point setting switch (setting operation element 12), the end position of the bar including the designated B point is set as the repeat playback end point (B point), and immediately thereafter (or the designated point). Playback to the end position of the phrase or measure including the B point), and then returns to the beginning position of the phrase including the A point. Thereafter, the playback is repeated from the beginning position of the phrase including the A point to the end position of the measure including the B point. When any of the AB repeat switches is operated again, the repeat mode is set to repeat off, and normal playback (playback without repeat playback) is resumed. In this case, since the setting of the A point is performed in the “phrase repeat mode”, the setting is performed in units of phrases, and the head position of the phrase including the A point is designated as the repeat playback start point (A point). The

  In the example shown in FIG. 7, during normal playback of automatic performance data PD (when repeat playback is not being performed), after passing the phrase mark PHM1, the user repeats the phrase repeat switch (setting) when the vertical arrow in the figure is ON. When the operator 12) is operated, the repeat mode is once set to the phrase repeat mode, and the reproduction of the automatic performance data PD immediately returns to the beginning position of the phrase being reproduced at the time when the operation is performed. Playback resumes. The repeat mode is set to the phrase repeat mode, and the subsequent point designation by the A point setting switch designates the phrase unit, that is, designates the head of the phrase including the A point as the A point. After that, after passing bar line ML7, that is, during playback of the seventh bar, the A point is designated, the repeat mode is set to the AB repeat standby mode, and the start position of phrase 2 including the A point is repeated playback. Designated as the starting point (point A). Then, after passing the phrase mark PHM2, when the user operates the phrase repeat switch again at the time of the vertical arrow OFF in the figure, the phrase repeat function is turned off, and the repeat mode is set to the AB phrase repeat standby mode. In the subsequent point designation by the B point setting switch, designation in bar units, that is, the end of the bar including the B point is designated as the B point. Therefore, the repeat mode is set to the AB phrase repeat mode after passing through the bar line ML11, that is, during the reproduction of the eleventh bar, and the end of the eleventh bar including the B point is set to the B point. Designated as (repeat playback end point), as shown in the figure, it immediately returns to the start position of phrase 2, and thereafter, the playback from the start position of phrase 2 to the end position of the eleventh measure is repeated. Thereafter, when the AB repeat-off switch is operated, the repeat mode is set to repeat-off, and normal playback (playback without repeat playback) is resumed.

  FIG. 8 is a flowchart showing the repeat reproduction process according to the embodiment of the present invention. This process is a process for realizing the repeat function according to the embodiment of the present invention described with reference to FIGS. 3 to 7, and is started every predetermined period (for example, 30 ms) by a timer interrupt.

  In step SA1, repeat playback processing is started. In step SA2, the presence / absence of a phrase repeat switch operation by the user is detected. If an operation is detected, the process proceeds to step SA3 indicated by a YES arrow, and if not detected, the process proceeds to step SA11 indicated by a NO arrow.

  In step SA3, the current repeat mode setting is determined. When the repeat mode is “AB repeat ON” (RM = AB_ON), the process proceeds to step SA4. When “OFF” (RM = OFF), the process proceeds to step SA5, and when “AB repeat standby” is set (RM = AB_S). The process proceeds to step SA7, and in the case of “AB phrase repeat standby” (RM = ABP_S), the process proceeds to step SA8, and in the case of “phrase repeat on” (RM = PR_ON) or “AB phrase repeat on” (RM = ABP_ON). Proceeds to step SA9. The initial setting of the repeat mode is “OFF” (RM = OFF). Therefore, after the automatic performance apparatus 1 is turned on, when the repeat playback process is activated for the first time, the repeat mode is set to “OFF”, which is the initial setting. Therefore, the process proceeds to step SA5 after step SA3. At the second and subsequent startups, it changes according to the repeat mode set in the following steps.

  In step SA4, AB repeat playback (see FIG. 4) currently being performed is canceled.

  In step SA5, the repeat mode is set to “phrase repeat on” (RM ← PR_ON), and in step SA6, the head is returned to the head position of the currently reproduced phrase, and playback is continued from the head position. Thereafter, the process proceeds to step SA11.

  In step SA7, the repeat mode is set to “AB phrase repeat standby” (RM ← ABP_S), and then the process proceeds to step SA11.

  In step SA8, the repeat mode is set to “AB repeat standby” (RM ← AB_S), and then the process proceeds to step SA11.

  In step SA9, the repeat mode is set to “off” (RM ← OFF), repeat reproduction is canceled in step SA10, and normal reproduction is continued. That is, if playback is being performed with phrase repeat (see FIG. 3), playback to the following phrase is continued without returning from the end of the phrase being repeated to the beginning of the phrase. If other repeats (see FIGS. 4 to 7) are being played back, the subsequent automatic performance data does not return from the designated point B (repeat playback end point) to point A (repeat playback start point). Continue playing. Thereafter, the process proceeds to step SA11.

  In step SA11, it is detected whether or not the user has operated the AB repeat switch. If an operation is detected, the process proceeds to step SA12 indicated by an arrow “YES”. If not detected, the process proceeds to step SA23 indicated by an arrow “NO”, and the current repeat reproduction process is terminated.

  In step SA12, the current repeat mode setting is determined. When the repeat mode is “off” (RM = OFF), the process proceeds to step SA13, when “phrase repeat on” (RM = PR_ON), the process proceeds to step SA15, and when “AB repeat standby” is set (RM = AB_S). The process proceeds to step SA17, and in the case of “AB phrase repeat standby” (RM = ABP_S), the process proceeds to step SA19, and in the case of “AB repeat on” (RM = AB_ON) or “AB phrase repeat on” (RM = ABP_ON). ) Proceeds to step SA21.

  In step SA13, the head position of the currently playing bar is designated as point A (repeat playback start point), and in step SA14, the repeat mode is set to “AB repeat standby” (RM ← AB_S). Thereafter, the process proceeds to step SA23, and the current repeat reproduction process is terminated.

  In step SA15, the head position of the currently reproduced phrase is designated as point A (repeat reproduction start point), and in step SA16, the repeat mode is set to “AB phrase repeat standby” (RM ← ABP_S). Thereafter, the process proceeds to step SA23, and the current repeat reproduction process is terminated.

  In step SA17, the end position of the currently playing bar is designated as point B (repeat playback end point), and in step SA18, the repeat mode is set to “AB repeat on” (RM ← AB_ON). Thereafter, the process proceeds to step SA23, and the current repeat reproduction process is terminated.

  In step SA19, the end position of the currently reproduced phrase is designated as point B (repeat reproduction end point), and in step SA20, the repeat mode is set to “AB phrase repeat on” (RM ← ABP_ON). Thereafter, the process proceeds to step SA23, and the current repeat reproduction process is terminated.

  In step SA21, the repeat mode is set to “OFF” (RM ← OFF), repeat reproduction is canceled in step SA22, and normal reproduction is continued. That is, if playback is being performed with phrase repeat (see FIG. 3), playback to the following phrase is continued without returning from the end of the phrase being repeated to the beginning of the phrase. If other repeats (see FIGS. 4 to 7) are being played back, the subsequent automatic performance data does not return from the designated point B (repeat playback end point) to point A (repeat playback start point). Continue playing. Thereafter, the process proceeds to step SA23, and the current repeat reproduction process is terminated.

  As described above, according to the embodiment of the present invention, the designation of the point A in the phrase repeat mode designates the head of the phrase including the point A as the repeat playback start point, and designates the point A when the repeat mode is repeat off. Specifies the beginning of a measure including the point A as a repeat playback start point. In the phrase repeat mode, the B point is designated by specifying the end of the phrase including the B point as the repeat playback end point. When the repeat mode is repeat off, the B point is designated by the measure including the B point. Specifies the end of the repeat playback end point.

  When the phrase repeat function is turned on (phrase repeat mode) and the AB repeat function is specified (point A and point B), the phrase position including the point A and the phrase end position including the point B Repeat playback is performed. Therefore, it is possible to repeat a plurality of phrases with a very simple operation.

  When the phrase repeat function is off (repeat off mode), the AB repeat function is instructed (point A designation), then the phrase repeat function is turned on (AB phrase repeat mode), and the AB repeat function is designated (point B designation) ), Repeat playback can be performed between the beginning position of the bar including the point A and the end position of the phrase including the point B.

  When the phrase repeat function is on (phrase repeat mode), the AB repeat function is instructed (point A is specified). After that, the phrase repeat function is off (AB phrase repeat mode) and the AB repeat function is instructed (point B is specified). ), It is possible to perform repeat playback between the phrase head position including the A point and the bar end position including the B point.

  According to the embodiment of the present invention, using the various repeat functions described above, the start point of repeat playback can be specified as the start position of a phrase or measure, and the end point can be specified as the end position of a phrase or measure. Therefore, it is possible to repeat playback of an arbitrary section of automatic performance data from a more musical viewpoint. In addition, you can learn a musical phrase. Furthermore, since the reproduction range (repeat section) can be set in detail, more efficient learning can be performed.

  In the above-described embodiment, the “AB repeat switch” designates the start point and the end point of repeat playback in units of measures, and the start and end positions of the bars included in the point are the repeat playback start point and Although designated as the end point, the positions of the points A and B may be designated as the repeat reproduction start point and the end point as they are.

  In the above-described embodiment, an example in which phrase repeat, AB repeat, repeat of multiple phrases, repeat from the bar start position to the phrase end position, and repeat from the phrase head position to the bar end position have been described. However, only some of these repeats may be possible. For example, only phrase repeats, AB repeats, and multiple phrase repeats may be possible. In this case, by operating the phrase repeat switch in the AB repeat standby mode, the AB repeat standby can be canceled and the normal phrase repeat mode can be set, or the repeat off mode can be set. In addition, the user may be allowed to set in advance whether or not to use the above-described various repeats.

  Moreover, it is preferable to display the currently set repeat mode and the positions of the points A and B (the number of measures, the phrase number, etc.) on the screen of the display device 14 of FIG.

  The phrase repeat switch and AB repeat switch are not limited to the dedicated hardware switch (setting operation element 12), and the display element of the operation element displayed on the display device 14 is pointed by the pointing device (setting operation element 12). Such a soft switch may be used. The phrase repeat switch is set to “Phrase Repeat On” for the first operation and “Phrase Repeat Off” for the second operation, but “Phrase Repeat On” is maintained while the switch operation continues. May be. In this case, in order to set the “AB phrase repeat mode”, for example, the AB repeat switch may be operated while the phrase repeat switch is operated.

  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.
