  The present invention relates to a performance recording apparatus and a program for recording a user performance. In particular, the present invention relates to a performance recording apparatus and program capable of appropriately setting an arbitrary position of the recorded performance as a playback position while recording the performance based on a user operation in real time.

Conventionally, musical performance data such as audio data generated by the operation of the performance operator and automatic performance data generated by the operation of the performance operator are recorded according to the operation of the performance operator by the user. In addition, an apparatus is known in which the recorded musical sound data is reproduced from a desired position after the performance is completed, so that the performance performed by the user himself / herself can be heard again from the middle. For example, there is an automatic performance device described in Patent Document 1 shown below. In the conventional apparatus described in Patent Document 1, an arbitrary position of automatic performance data stored in advance can be assigned to a predetermined switch as a reading start position, and the user can set the switch. By operating, the stored automatic performance data can be reproduced from the middle. Further, it is disclosed that a user can select and assign a reading start position to be assigned to the switch as appropriate.
JP 09-114456 A

  By the way, in the conventional apparatus as described above, after the automatic performance data related to the entire performance is recorded in advance, the automatic performance data related to the entire recorded performance is appropriately reproduced, and the performance portion that the user wants to listen to again is appropriately determined. The position of the corresponding automatic performance data is searched and registered as a read start position (that is, a reproduction start position). However, this operation is a post-operation after the end of the performance, which is troublesome and cumbersome, especially for performance lessons where users often want to listen to the performance themselves immediately after the performance. There was a problem that it was not suitable at all and was difficult to use.

  The present invention has been made in view of the above points, and provides a performance recording apparatus and program capable of allocating a portion that a user wants to listen to again after the performance is completed while recording the performance operation by the user in real time. The purpose is to provide.

  The performance recording apparatus according to the present invention acquires a musical sound data generated in response to a predetermined performance operation, a storage means for storing music data, a playback means for reading out the music data from the storage means and reproducing the music data, Recording means for recording the acquired musical sound data in real time in a predetermined performance storage means in the order of generation, and an arbitrary read-out of the recorded musical sound data in response to operation when real time recording of musical sound data is performed by the recording means One or more operators that individually give instructions for assigning playback positions, and a time point before the time point when the operator is operated in association with the operated operator in accordance with the instruction. The recording position of the musical sound data recorded in the performance storage means and the front of the music data read out and reproduced at a time point before the time point when the operation element is operated. And a storage position in the storage means comprises a position memory means for storing at least.

  According to the present invention, the musical sound data generated in response to a predetermined performance operation is recorded in real time in a predetermined performance storage means in the order of generation, and instructions for assigning arbitrary reproduction positions for reading the recorded musical sound data are individually given. Do. As a result, it is possible to easily set the location where the performance is desired to be re-listened after the performance is finished, in accordance with the real-time performance. In this case, the recording position in the performance storage means of the musical sound data recorded at a time point before the time when the operation element is operated and the time point when the operation element is operated. At least the storage position in the storage means of the music data read and reproduced at the previous time point is stored. According to this, since the point where you want to re-listen to the performance after the performance ends is automatically set and stored at the performance recording position at a time point that is later in time than the setting instruction, The user can easily and efficiently designate a part that he / she wants to hear again immediately after the performance is finished, without omitting the protruding part.

  The present invention may be constructed and implemented not only as an apparatus invention but also as a method invention. Further, the present invention can be implemented in the form of a program of a processor such as a computer or a DSP, or can be implemented in the form of a storage medium storing such a program.

  According to the present invention, since a performance according to a user operation is being recorded in real time, it is possible to store an arbitrary position of the recorded performance as a playback position with a simple operation. There is an effect that it is possible to easily and efficiently designate a part to be re-listened immediately after the performance is finished.

  Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

  FIG. 1 is a hardware configuration block diagram showing the overall configuration of an electronic musical instrument to which a performance recording apparatus according to the present invention is applied. The electronic musical instrument shown in this embodiment is controlled by a microcomputer including a microprocessor unit (CPU) 1, a read only memory (ROM) 2, and a random access memory (RAM) 3. The CPU 1 controls the operation of the entire electronic musical instrument. To this CPU 1, the ROM 2, RAM 3, detection circuits 4 and 5, display circuit 6, tone generator circuit 7, effect circuit 8, external storage device 10, MIDI interface (I / F) 11 and the like are connected to the CPU 1 via the data and address bus 1D. Communication interfaces (I / F) 12 are connected to each other. Further, the CPU 1 is connected to a timer 1A for measuring the interrupt time and various times in the timer interrupt process (interrupt process). For example, the timer 1A generates a clock pulse, and gives the generated clock pulse to the CPU 1 as a processing timing command or to the CPU 1 as an interrupt command. The CPU 1 executes various processes according to these instructions.

  The ROM 2 stores various programs executed by the CPU 1 and various data. The RAM 3 is used as a working memory that temporarily stores various data generated when the CPU 1 executes a predetermined program, or as a memory that stores a currently executed program and related data. A predetermined address area of the RAM 3 is assigned to each function. For example, a musical tone data (audio data) generated from the tone generator circuit 7 in response to a real-time performance by a user is recorded from the external storage device 10 in a ring buffer for recording data in the order of data generation It is used as a memory for temporarily storing a marker table (see FIG. 8 described later), a register, a flag, or the like.

  The performance operator 4A is, for example, a keyboard provided with a plurality of keys for selecting the pitch of a musical tone, and has a key switch corresponding to each key. The keyboard etc. can be used not only for manual playing by the user's own playing but also as input means for selecting a song for which the performance is to be recorded. The detection circuit 4 generates a detection output by detecting the pressing and release of each key of the performance operator 4A. In this embodiment, musical tone signals (audio data) generated from the tone generator circuit 7 in response to the user's operation of the performance operator 4A are recorded in the ring buffer of the RAM 3 in real time in the order of generation (time order). To go.

  As shown in FIG. 2, which will be described later, a panel operator (switch or the like) 5A is a “lesson start / end switch” B1 for instructing start and end of recording in a ring buffer for real-time performance, for example, recording real-time performance “Record switch” B2, which instructs to record a check point (this is called a marker position) as an indication of an arbitrary playback position (playback range) to be played after completion, in response to being operated during real-time performance. “Recording switch” B3 for instructing the recorded performance to be reproduced within a predetermined range based on the marker position recorded in accordance with the operation of the “recording switch” B2, after recording the performance. When operated, an instruction to assign an arbitrary playback position to the performance being recorded is given, while If it is operated after the completion of recording-time playback, and the like "marker setting button" M1~M4 specifying the tone reproduction at the assigned playback position (see FIG. 2). Of course, in addition to these, a numeric keypad for inputting numeric data, a keyboard for inputting character data, and a predetermined pointing device displayed on the display 6A, which are used for selecting, setting and controlling the pitch, tone color, effect, etc. Various operators such as a mouse used for operation may be included. The detection circuit 5 detects the operation state of each switch and outputs switch information corresponding to the operation state to the CPU 1 via the data and address bus 1D.

  The display circuit 6 is a “playback position display screen” (see FIG. 2 to be described later) that displays various types of information relating to marker positions that are set as appropriate by the user during performance recording on a display 6A composed of, for example, a liquid crystal display panel (LCD) or CRT. See below), a list of song data that can be played as a model performance sample that is prepared in advance or an accompaniment that assists the performance when the user performs, a score of the performance target song that the user refers to during performance, The score of the reproduction range to be referred to during performance reproduction or the control state of the CPU 1 is displayed. By referring to these various types of information displayed on the display 6A, the user can easily perform operations such as selecting a tune to be recorded as a performance recording target and specifying a playback position in the recorded performance.

  Here, the “playback position display screen” displayed on the display 6A will be described with reference to FIG. FIG. 2 is a conceptual diagram showing an example of a “playback position display screen”. However, FIG. 2 illustrates a screen when marker positions are already assigned to the three buttons M1 to M3.

  The “playback position display screen” shown in FIG. 2 is assigned to each of the buttons M1 to M4 to predetermined display areas H1 to H4 arranged so as to correspond to the “marker setting buttons” M1 to M4, respectively. Information on the “marker position” is displayed. The information related to the “marker position” displayed on this screen includes an elapsed time, a title, the number of times, and a position as shown in the figure. The “elapsed time” represents the elapsed time from the start time of performance recording started in response to the operation of the “lesson start / end switch” B1 to the operation of the button (M1 to M4). The “title” is a title given to the song according to the song name information included in the song data being played back during performance recording. “Number of times” indicates how many times the music piece has been repeatedly played, and the marker position is assigned at the time of repeated performance. “Position” represents a musical musical position (for example, the number of bars or the number of beats) in the audio data recorded during performance of the marker position assignment operation and the music data being reproduced. In this embodiment, only the “marker setting button” M4 is a button to which the marker position is not assigned, and such a marker position is not assigned to the display area H4 corresponding to the unassigned button M4. “The marker position is not assigned” is displayed. The marker position assignment state to each of the “marker setting buttons” M1 to M4 displayed on the “playback position display screen” is displayed according to the stored contents stored in a marker table (see FIG. 8) described later. The Displaying various information related to the performance recorded at the time when such a marker position is assigned allows the user to easily search for the performance he / she wants to listen to after the performance is completed.

  Although not shown in this embodiment, the “playback position display screen” is a musical score related to the performance target music at the time of performance recording according to the user's keyboard operation or audio recorded according to the user's keyboard operation. It goes without saying that it can be displayed on the display 6A at the same time together with the score of the corresponding range at the time of data reproduction. In such a case, the user may be allowed to select a screen to be displayed at the same time.

  Returning to the description of FIG. 1, the tone generator circuit 7 can simultaneously generate musical tone signals (for example, audio data) on a plurality of channels, and the performance operator 4A provided by the user via the data and address bus 1D. Various performance information generated in response to the above operation or generated based on music data is input, and a musical sound signal is generated based on the performance information. The musical sound signal generated from the sound source circuit 7 is given an effect via the effect circuit 8 and is generated from the sound system 9 including an amplifier and a speaker. Any conventional configuration may be used for the sound source circuit 7, the effect circuit 8, and the sound system 9. For example, the tone generator circuit 7 may employ any of various tone synthesis methods such as FM, PCM, physical model, formant synthesis, etc., or may be configured with dedicated hardware, or configured with software processing by the CPU 1. May be.

  The external storage device 10 includes various data such as a marker table (see FIG. 8), song data for automatically performing a model performance or accompaniment (for example, MIDI format automatic performance data), various control programs executed by the CPU 1, and the like. Data related to control is stored. When no control program is stored in the ROM 2, the control program is stored in the ROM 2 by storing the control program in the external storage device 10 (for example, a hard disk) and reading it into the RAM 3. The CPU 1 can be operated in the same manner as in the case. In this way, control programs can be easily added and upgraded. The external storage device 10 is not limited to a hard disk (HD), but a flexible disk (FD), a compact disk (CD-ROM / CD-RAM), a magneto-optical disk (MO), a DVD (Digital Versatile Disk), etc. Any storage device may be used as long as the storage device uses various external storage media. Alternatively, a semiconductor memory such as a flash memory may be used.

  The MIDI interface (I / F) 11 inputs the automatic performance data in the MIDI format to the electronic musical instrument from another externally connected MIDI device 11A or the like, or sends the automatic performance data in the MIDI format from the electronic musical instrument to the other This is an interface for outputting to the MIDI device 11A or the like. The communication interface (I / F) 12 is connected to a wired or wireless communication network X such as a LAN, the Internet, or a telephone line, and is connected to the server computer 12A via the communication network X, and the server computer 12A. This is an interface for taking control programs or various data from the electronic musical instrument side. That is, when the control program and various data are not stored in the ROM 2 or the external storage device 10 (for example, hard disk), it is used to download the control program and various data from the server computer 12A. Such a communication interface 12 may include both of a wired interface and a wireless interface.

  The performance operator 4A is not limited to a keyboard instrument, but may be any type of instrument such as a stringed instrument, a wind instrument, or a percussion instrument. Not only the form of a musical instrument but also a simple button or switch shape may be used. Further, the electronic musical instrument is not limited to one in which the performance operator 4A, the display 6A, the sound source circuit 7 and the like are built in one apparatus body, but each is configured separately, and each of the electronic musical instruments is configured using communication means such as a MIDI interface or various networks. Needless to say, the apparatus may be configured to be connected. Furthermore, the performance recording apparatus according to the present invention is not limited to the form of the electronic musical instrument as described above, and may be applied to any form of apparatus / equipment such as a sequencer, a personal computer, a karaoke apparatus, or a game apparatus.

  The electronic musical instrument to which the performance recording apparatus according to the present invention shown in FIG. 1 is applied records audio data generated in response to a keyboard operation (performance operation) by the user, and records the audio data while recording the audio data. An arbitrary check point (information indicating an arbitrary reproduction position for reading performance-recorded audio data, which is called a marker position) can be assigned to the marker setting buttons M1 to M4 at any time according to an instruction. I have to. Therefore, processing relating to recording of audio data generated in accordance with the performance operation (ie, performance recording) and marker position assignment will be described below in accordance with the operation order of the switches B1 to B3 and the marker setting buttons M1 to M4 shown in FIG. Explained.

  First, processing that is started in response to pressing of the “lesson start / end button” B1 will be described with reference to FIGS. FIG. 3 is a flowchart showing an example of the “recording start process”. As shown in FIG. 3, step S1 secures a predetermined area of free space in the RAM 3 as a data storage area for temporarily recording audio data generated from the tone generator circuit 7 in response to a performance operation by the user. In step S2, a recording segment of a predetermined size from the beginning of the reserved empty area is recorded as a recording segment capable of recording audio data for a predetermined time interval as a “performance recording process (recording driver)”. Notify In step S3, the "performance recording process (recording driver)" is activated. After this process, the “performance recording process (recording driver)” starts executing the process and records the audio data generated from the tone generator circuit 7 according to the performance operation by the user for each recording segment in the order of generation. . The detailed description of the “performance recording process (recording driver)” will be described later (see FIG. 5 described later). Step S4 resets the lesson elapsed time, that is, the elapsed time from the start time of performance recording until the marker setting buttons M1 to M4 are operated, and then starts measuring the lesson elapsed time. Here, the recording is started by pressing the “lesson start / end button” B1, but the recording may be started immediately after the electronic musical instrument main body is turned on.

  FIG. 4 is a flowchart showing an example of “music data reproduction processing”. This “song data playback process” is repeatedly executed many times between the start of performance recording and the end of performance recording. For example, in order to assist the performance operation by the user, Musical sounds such as performances and accompaniments are generated, and musical scores such as songs and accompaniments targeted for performance recording are displayed. This processing is started by a general operation for starting reproduction of music data performed by an electronic musical instrument or the like. That is, one of music data stored in the external storage device is selected with a setting operator (not shown), and the operation is started by operating the operator (not shown). Also, this process ends when the music data is played back and the music data reaches the end, or when the music data playback is interrupted by an operator (not shown).

  As shown in FIG. 4, in step S11, it is determined whether or not the music data is being reproduced for the first time from the start of performance recording (that is, the first time after the start of the lesson). If it is determined that the music data has not been reproduced for the first time from the start of the lesson (yes in step S11), the “number of times the music is repeated” is reset (step S12). In step S13, "the number of times the music is repeated" is increased by one. In step S14, music data reproduction processing is performed. In step S15, the musical score relating to the model and the accompaniment corresponding to the performance target music displayed on the display 6A according to the selection of the performance target music is updated as the performance progresses. Note that the electronic musical instrument has a function of changing the playback location to a predetermined position of the song data going back in time from the playback location of the currently playing song data (that is, a rewind function) as a playback function of the song data. In such a case, 1 is added to the “number of times the music is repeated” each time the rewinding operation is performed. When the user has a rewind function, the user can record the performance from the same music position many times each time the rewind operation is repeated. Further, after the lesson starts, the music data to be reproduced can be changed, and the number of repetitions is counted for each music data.

  FIG. 5 is a flowchart showing an example of the “performance recording process”. The process is started in response to a start instruction (step S3 in FIG. 3) from the “recording start process” and processed in response to a stop instruction (step S41 in FIG. 9) from a “recording end process” to be described later. Until it is stopped, it is repeatedly executed at predetermined time intervals by a timer interrupt. This process is a process for preparing a storage area for recording a performance by the user, and updating the storage area used for each recording segment that can record audio data for a predetermined time interval. Is what you do.

  As shown in FIG. 5, step S21 determines whether or not the recording segment has reached the end of the data storage area on the RAM 3 secured in advance. If it is determined that the recording segment has reached the end of the data storage area on the RAM 3 secured in advance (yes in step S21), an area of a predetermined size from the top of the data storage area is set as the next recording segment. A recording segment is designated (step S22). On the other hand, if it is determined that the recording segment has not reached the end of the data storage area on the RAM 3 secured in advance (no in step S21), the next recording segment is made the current recording segment in the data storage area. A subsequent area of a predetermined size is designated (step S23). In step S24, referring to the marker table (see FIG. 8 described later), the designated next recording segment is the reproduction position designated by the marker position (the “recording start address stored in the marker table described later). ”To“ recording end address ”(data storage area range). When it is determined that the designated next recording segment is at the reproduction position designated by the marker position (yes in step S24), the reproduction position designated by the marker position is excluded as the next recording segment. A recording segment having a predetermined size is designated again from the beginning of the subsequent data storage area (step S25). In step S26, audio data generated in response to a performance operation by the user is recorded in the designated recording segment. By doing so, the audio data is recorded in the data storage area in the order of transmission.

  Next, after the performance recording is started in response to pressing of the “lesson start / end switch” B1, one of the “record switch” B2 and “marker setting buttons” M1 to M4 is simultaneously pressed. The process started in response to this will be described with reference to FIG. FIG. 6 is a flowchart showing an example of the “marker recording / deleting process”. This process is a process of assigning an arbitrary reproduction position (reproduction range) to be reproduced after the performance recording is finished to the “marker setting buttons” M1 to M4.

  In step S31, it is determined with reference to the marker table (see FIG. 8) whether the pressed “marker setting buttons” M1 to M4 are already assigned playback positions. If it is determined that the pressed button has already been assigned a playback position (yes in step S31), the data corresponding to the marker button is deleted from the marker table (step S32). Corresponding to the marker button in the marker table after deleting the corresponding data from the marker table or when it is determined that the pressed button has not yet been assigned the playback position (no in step S31). As the data to be recorded, the marker position address (that is, the recording segment position of the audio data written when the marker button is operated), the number of repetitions of the song, the lesson elapsed time, and reference data to the song data are stored, and the marker position The musical song position corresponding to the audio data recorded at the address is specified based on the song data being reproduced, and the specified musical song position is stored in the song position at the marker position (step S33). Also, in the data storage area, the addresses before / after a predetermined range from the address of the marker position are stored as the start address / end address, respectively, and the musical music corresponding to the audio data recorded at the start address / end address is stored. The position is specified based on the song data being played back, and the specified musical song position is stored in the first song position and the last song position in the marker table (step S34). A step S35 updates the display of the “reproduction position display screen” (see FIG. 2) based on the updated marker table.

  Next, the above-described “performance recording process” and “reproduction position recording process” will be described using specific examples. FIG. 7 is a schematic diagram for explaining operations relating to performance recording and reproduction position recording. Here, in order to make the explanation easy to understand, an empty area from the address “0x0000” to the address “0XFFFF” is reserved in advance as a data storage area (which is a ring buffer), and the reserved data storage area An example of repeated recording will be described.

  At the start of performance recording, lesson elapsed time starts to be measured (00:00:00), and audio data generated in response to the performance operation is recorded from the start address “0x0000” of the data storage area. It is memorized sequentially. When the marker setting button M1 is operated together with the recording switch B2 at the lesson elapsed time “00:03:00”, the recording segment position (marker position address) of the audio data recorded when the marker setting button M1 is operated “0x3000” ”The number of times the song is repeated when the marker setting button M1 is operated“ first time ”, the song position“ 4th measure 1st beat ”of the song data reproduced when the marker setting button M1 is operated, and when the marker setting button M1 is operated Each lesson elapsed time “00:03:00” and pointers indicating the music data being played back when the marker setting button M1 is operated (reference data to the music data: not shown here) are indicated in the marker table. To record. Then, from the address “0x3000” at the marker position, the head address “0x1000” before the predetermined range and the end address “0x4FFFF” after the predetermined range are obtained and recorded in the marker table. In this manner, the marker setting button M1 is assigned a reproduction position for reproducing the audio data stored in the range from the address “0x1000” to the address “0x4FFFF”.

  Here, the data structure of the marker table will be described with reference to FIG. FIG. 8 is a schematic diagram showing an embodiment of the data structure of the marker table. As shown in FIG. 8, the marker table relates to a data storage area for storing audio data for each unique number (marker number) assigned to “marker setting buttons” M1 to M4 prepared in advance on the panel. Information, information on song position, and other information can be broadly divided. Information relating to the data storage area includes a recording start address, a marker position address, and a recording end address. The address of the marker position is data indicating the address of the data storage area where the performance (audio data) is recorded when the “marker setting button” corresponding to the performance recording is operated. The recording start address is data indicating an address preceding the marker position by a predetermined range. In other words, in the storage area indicated by the address at the beginning of the recording, a performance at a point in time that is earlier than the point in time when the “marker setting button” is operated is recorded. The recording end address is data indicating an address after a predetermined range from the address of the marker position. That is, a performance at a time later than the time when the “marker setting button” is operated is recorded in the data storage area indicated by the recording end address.

  Information on the music position includes the music position at the beginning of recording, the music position at the marker, and the music position at the end of recording. The music position of the marker is data indicating the musical music position (for example, the number of bars, the number of beats, etc.) of the corresponding music based on the music data being played back when the “marker setting button” is operated at the time of performance recording. is there. According to the information, a “position” display on the screen is performed. These song positions are obtained based on song data. For example, there are methods such as counting the timing data in the song data up to the corresponding location in the song data, or counting the number of bar data if the song data includes the bar data. Since the method is publicly known, the description is omitted. The recording start address is data indicating an address preceding the marker position by a predetermined range. The recording end address is data indicating an address after a predetermined range from the address of the marker position. The music position at each time point corresponds to the address at each time point. That is, the recording head address and the recording head music position, the marker position address and the marker music position, and the recording end address and the recording end music position are associated with each other.

  Other information includes the number of repetitions of the song, the lesson elapsed time, and reference data to the song data. The number of repetitions of the tune is the number of performance repetitions at the time of recording the marker position, which indicates how many times the repeated performance is recorded. According to the information, the “number of times” display on the playback position display screen is performed. The lesson elapsed time represents the elapsed time from the start of performance recording (or the start of music data playback) in which the marker position is recorded. According to the information, the “elapsed time” display on the reproduction position display screen is performed. The reference data to the song data represents a pointer indicating the storage position (or storage range) on the external storage device for the song data reproduced at the time of performance recording. According to the information and the information on the music position of the marker, the music data is also reproduced from the corresponding position in accordance with the reproduction of the performance record when the performance record is reproduced from the marker position. In other words, storing the reference data to the music data and the music position of the marker in the marker table is a marker setting button among the storage positions on the external storage device of the music data that was being reproduced according to the performance during performance recording. This corresponds to storing the storage position of the location corresponding to the range corresponding to the operation. Of course, as reference data for the music data, with respect to the music data reproduced at the time of performance recording, the storage position of the external storage device corresponding to the music position at the beginning of recording and the external storage device corresponding to the music position at the end of recording are recorded. A pointer indicating each storage position may be used. Further, not only the reproduction of the music data, but also the “title” display on the reproduction position display screen is performed according to the music name information recorded in the music data referred to by the information.

  Returning to the description of FIG. 7, when the marker setting button M2 is operated together with the recording switch B2 at the lesson elapsed time “00:06:00”, the marker position is changed in the same manner as when the marker setting button M1 is operated. Address “0x6000”, song repeat count “first”, song data song position “7 bars 1st beat”, lesson elapsed time “00:06:00”, reference data to song data (not shown), The start address “0x4000” and the end address “0x7FFFF” are stored in the marker table. That is, a playback position for playing back audio data recorded in the range from the address “0x4000” to the address “0x7FFFF” is assigned to the marker setting button M2.

  When the first write to the data storage area that is the ring buffer is completed and the second write is performed, when the end of the range secured in the data storage area reaches “0xFFFF”, the data storage area The recording segment is designated so as to return to the top “0x0000” of the range secured in the above. In the example shown in FIG. 7, in the range from “0x0000” to “0x0FFF”, the second-round recording (audio data) is overwritten and stored on the audio data recorded in the first round (two rounds in the figure). Eye records shown in black). When recording further proceeds, the performance of the second lap is recorded so that the range of “0x1000” to “0x7FFF” is skipped and the recording of the first lap is overwritten from “0x8000”. This is because the range from “0x1000” to “0x7FFF” corresponds to the playback position that has already been assigned to the marker setting buttons M1 and M2, so that the second round of recording is not overwritten and recorded in the first round for that range. The recorded performance is kept. When the marker setting button M3 is operated together with the recording switch B2 at the lesson elapsed time “00:21:00”, the marker position address “0xB000”, the number of times of song repetition “1”, the song data song position “5th measure 1st beat”, lesson elapsed time “00:21:00”, reference data to music data (not shown), start address “0x9000”, end address “0xCFFFF” are stored in the marker table. That is, the marker setting button M3 is assigned a playback position for playing back audio data recorded in the range from the address “0x9000” to the address “0xCFFF” as the playback position.

  Next, a process that is started in response to the “lesson start / end button” B1 being pressed again after the performance recording is started (that is, after the “recording start process” shown in FIG. 3 is started). This will be described with reference to FIG. FIG. 9 is a flowchart showing an example of the “recording end process”. In step S41, the “performance recording process (recording driver)” (see FIG. 5) and the “music data reproduction process” (see FIG. 4) are stopped. As a result, the recording of the performance and the reproduction of the music data or the update of the score display are stopped. In step S42, only the audio data recorded in the area specified by the marker table in the data storage area secured on the RAM 3 is left, and the audio data recorded in other areas is discarded. .

  Next, after the end of the performance recording associated with each of the above processes, the process started in response to pressing one of the “marker setting buttons” M1 to M4 together with the “playback switch” B3 shown in FIG. This will be described with reference to FIG. FIG. 10 is a flowchart illustrating an example of “reproduction processing”. The step S51 refers to the marker table, reads out the audio data in the corresponding range based on the recording start address and the recording end address corresponding to the operated marker setting button and repeatedly reproduces it, Based on the reference data, the music data in the corresponding range is read and reproduced repeatedly. In step S52, the musical score displayed on the display is updated based on the song data in accordance with the reproduction.

In the above-described embodiments, the performance recording is performed by audio data. However, the present invention is not limited to this. For example, any performance recording such as MIDI automatic performance data can be performed as time passes. It may be.
In the above-described embodiment, music data for reproducing a model performance or accompaniment (automatic performance data) is shown as an example of data for specifying a musical song position. However, the present invention is not limited to this. For example, it may be data prepared separately from song data, such as musical score display data whose display is updated at a predetermined tempo, or lyric data that displays karaoke lyrics managed by tempo, measure and beat. However, it is necessary that the musical song position displayed on the “playback position display screen” can be specified as time elapses. In the above example, the data must have tempo, measure and beat.
The marker position instruction may be remotely set via a network from an external device such as a personal computer terminal or a portable communication terminal such as a mobile phone or PDA.
It should be noted that a “delete button” for deleting the assigned marker position may be provided, and by operating the delete button and any one of the marker setting buttons M1 to M4 at the same time, the operated marker setting buttons M1 to M4. It is also possible to delete the playback position assigned to the.

Note that the addresses at the beginning and end of recording are automatically set based on the address of the marker position, but the user can arbitrarily set a predetermined range before and after the marker position referred to at this time. May be within a predetermined range. In addition, the range designation mode may be a data size (for example, 1 kbyte before and after), a time (for example, 1 second before and after), or a song position (for example, 3 bars before and after). There may be. Furthermore, the width of the predetermined range may be different before and after (for example, 1 second before and 2 seconds after).
Note that only the audio data recorded in the area corresponding to the playback position assigned to each marker setting button M1 to M4 is stored in the external storage device 10 or an external device, and other areas are stored. You may try not to memorize it. In this case, however, it goes without saying that each address in the marker table needs to be rewritten to the address of the external storage device 10 or external device on the storage side.
Note that audio data and a marker table may be combined to be stored for each song.
