  FIG. 2 is a diagram illustrating an example of a data format of the playlist data. The playlist data is data describing the reproduction order of each MIDI song data in order to continuously reproduce a plurality of MIDI song data, and is created or edited by a user or the like.

  As shown in the figure, the playlist data 21 includes a plurality of item n data (n = 1, 2,...) 21a.

  Each item n data 21a is composed of the same data format, and is composed of number data 21a1, check mark data 21a2, title data 21a3, and MIDI song data storage path data 21a4. Here, the number data 21a1 is data indicating the number of the MIDI song data to be reproduced among a plurality of MIDI song data to be reproduced by the playlist data 21. The check mark data 21a2 is data indicating whether or not the MIDI song data is to be subjected to MIDI to Audio processing. Specifically, when a check mark is added to the MIDI song data, the MIDI song data is subjected to MIDI to AUDIO processing. When a check mark is not added thereto, the MIDI song data is subjected to MIDI to AUDIO processing. Don't make it. The title data 21a3 is data indicating the name of the MIDI song data. The MIDI song data storage path data 21a4 is data indicating a storage position of the MIDI song data in the external storage device 10 by a path.

  In the present embodiment, the playlist data is stored in the RAM 7. In this case, the playlist data is erased when the power supply to the RAM 7 is stopped, so that the playlist data is always retained. If desired, the playlist data may be stored in the external storage device 10 or a newly provided RAM with a backup power source.

  Since the number of MIDI song data stored in advance in the apparatus is generally large, in the present embodiment, the MIDI song data is stored in the external storage device 10 because of the data capacity. . Therefore, the MIDI song data storage path data 21a4 is data indicating the storage position in the external storage device 10 as described above. However, once the MIDI song data is reproduced according to the playlist data 21, all the reproduced MIDI song data is read from the external storage device 10 into the RAM 7 and held as it is. The MIDI song data storage path data 21a4 may indicate the storage position in the RAM 7. However, in the automatic performance data processing apparatus of this embodiment, when the MIDI song data is reproduced according to the playlist data 21, the MIDI song data for one song to be reproduced or being reproduced is stored in the RAM 7. The data is read into the playback area (not shown) and held as it is. However, when the playback of the MIDI song data is finished and the playback shifts to the next MIDI song data, the MIDI song data is read into the playback area. As a result, since only one piece of MIDI song data is held in the reproduction area, the MIDI song data storage path data 21a4 always indicates the storage position in the external storage device 10.

  Furthermore, the data format of the MIDI song data is an “event + relative time” sequence indicating the time of occurrence of a performance event as the time from the previous performance event, and the time of occurrence of a performance event as an absolute time within a song or measure. The sequence of “event + absolute time”, the pitch of the note and the length of the note or the sequence of “pitch (rest) + note length” indicating each performance event by the rest and rest length, the minimum performance in the RAM 7 Any format may be used such as a “solid method” in which an area for each resolution is secured and the performance event is stored in an area corresponding to the time at which the performance event occurs.

  Note that the data format of the playlist data described above is merely an example, and other formats may be adopted.

  An overview of the MIDI to AUDIO processing executed by the automatic performance data processing apparatus configured as described above will be described first with reference to FIGS. 3 and 4 and then in detail with reference to FIGS. .

  FIG. 3 is a block diagram showing the concept of MIDI to AUDIO processing.

  As shown in the figure, when the user prepares playlist data 21 and instructs the start of digital recording (batch MIDI to AUDIO), the automatic performance data processing apparatus according to the present embodiment first plays back the playlist data 21. Of the plurality of instructed MIDI song data, the MIDI song data described first in the playlist data 21 is read from the external storage device 10 and stored in the reproduction area of the RAM 7.

  Next, the automatic performance data processing apparatus of the present embodiment sequentially reproduces MIDI song data stored in the reproduction area from the top. Specifically, each performance event included in the MIDI song data is read at the timing of generation thereof, and a parameter corresponding to the read performance event is written to a predetermined register of the tone generator circuit 13, and then the audio signal is sent to the tone generator circuit 13. Instruct the generation of. In response to this, a corresponding audio signal is generated from the tone generator circuit 13, and this audio signal is digitally recorded by the digital audio recorder 23. Here, the digital audio data generated by digital recording may be any data such as uncompressed WAV data, compressed audio data such as MP3 (MPEG audio layer 3), and a general-purpose format. However, it may be in a format unique to each manufacturer.

  Then, MIDI song data to be reproduced next is read out from the external storage device 10 to the reproduction area, and similarly reproduced and digitally recorded. In the automatic performance data processing apparatus of the present embodiment, As modes for digital recording (MIDI to AUDIO mode), two types of modes 1 and 2 are provided, and different digital recording (MIDI to AUDIO processing) is performed according to the mode selected by the user. FIG. 4 is a diagram for explaining two types of MIDI to Audio processing corresponding to these two types of modes. As shown in the figure, mode 1 is a mode in which each of a plurality of MIDI song data is digitally recorded as a corresponding individual digital audio song data. Digital audio song data files have the same number as the number of MIDI song data. Generated. Mode 2 is a mode in which a plurality of MIDI song data are grouped in the order of playback and digitally recorded as one digital audio song data. One digital audio song data file is generated regardless of the number of MIDI song data. The

  The features of the present invention are not in the configuration of the digital audio recorder 23 or the digital recording method thereof, so that a known digital audio recorder 23 is used. Therefore, further description of the digital audio recorder 23 is omitted.

  As described above, in the MIDI to AUDIO processing, digital audio song data corresponding to a plurality of automatic performance data is easily generated in a batch based on playlist data already prepared for reproducing a plurality of automatic performance data. be able to. In mode 1, individual digital audio song data files corresponding to each of a plurality of automatic performance data can be easily generated, while in mode 2, a file including a plurality of automatic performance data is supported. One digital audio song data file can be easily generated. Since the user can select either mode 1 or mode 2, the user's favorite digital audio data can be easily generated.

  Next, this MIDI to Audio process will be described in detail.

  FIG. 5 is a flowchart showing the procedure of the MIDI to Audio process executed by the automatic performance data processing apparatus of this embodiment, particularly the CPU 5.

  As shown in the figure, first, when the user prepares playlist data (step S1) and presses a reproduction switch (not shown) provided in the setting operator 2, for example, the playlist data is described in the playlist data. In this order, the MIDI song data is continuously reproduced (step S2).

  Next, the user designates the MIDI to AUDIO mode by pressing one of two mode switches (not shown) provided in the setting operation element 2 corresponding to, for example, the two kinds of MIDI to AUDIO modes (step). After S3), when a collective MIDI to AUDIO switch (not shown) provided in the setting operation element 2 is pressed (step S4), a MIDI to AUDIO process corresponding to the designated MIDI to AUDIO mode is executed (step S5).

  FIG. 6 is a flowchart showing the procedure of the MIDI to Audio mode 1 process executed when mode 1 is designated as the MIDI to Audio mode.

  As shown in the figure, in the MIDI to Audio mode 1 process, among the plurality of item n data 21a included in the prepared playlist data, the first item n data 21a to which the check mark data 21a2 is given a check mark is stored. The MIDI song data at the position indicated by the MIDI song data storage path data 21a4 is read from the external storage device 10 to the reproduction area of the RAM 7, and the reproduction is started. The first performance event included in the MIDI song data is generated at the time of occurrence. Then, the parameter corresponding to the read performance event is supplied to the tone generator circuit 13, and in response to this, digital recording of the audio signal output from the tone generator circuit 13 is started by the digital audio recorder 23 (step S11).

  Then, the performance event is supplied to the tone generator circuit 13 and the digital recording of the audio signal output from the tone generator circuit 13 is repeated until the last performance event included in the MIDI song data (step S12). When the digital recording of the performance event is completed, the digital recording is temporarily ended, and the digitally recorded digital audio data is stored in the file format in the external storage device 10 corresponding to the first MIDI song data (step S13). Here, saving in file format means, for example, adding header data that describes bibliographic items such as recording date and time and file name, and end data that indicates the end of the file, in addition to digitally recorded digital audio data. It means to do. The recording date and time is usually automatically described by the clock function built in the automatic performance data processing apparatus of this embodiment, but the file name is automatically generated and described. Or what is designated by the user may be described. Examples of automatically generated file names include, for example, a file name of the basic MIDI song data (indicated by the title data 21a3), a predetermined character string + sequential number (AUDIO_001, AUDIO_002) , AUDIO_003, ...).

  The above-mentioned digital recording and saving in the file format are MIDI songs corresponding to all the item n data 21a in which the check mark data 21a2 is checked among the plurality of item n data 21a included in the playlist data. This is performed for data (steps S14 → S11 → S12 → S13 → S14 → return).

  As described above, in the present MIDI to AUDIO mode 1 process, among the plurality of item n data 21a included in the playlist data, the MIDI corresponding to each of all the item n data 21a to which the check mark data 21a2 is given a check mark is provided. For each song data, one digital audio song data file is generated and stored.

  FIG. 7 is a flowchart showing the procedure of the MIDI to Audio mode 2 process executed when the mode 2 is designated as the MIDI to Audio mode.

  This MIDI to Audio mode 2 process is performed on all item n data 21a in which a check mark is given to the check mark data 21a2 among the plurality of item n data 21a included in the playlist data, compared to the MIDI to Audio mode 1 process. The difference is that the corresponding MIDI song data is reproduced in order from the youngest number data 21a1, recorded digitally, and one digital audio song data file is generated.

  For this reason, in this MIDI to AUDIO mode 2 process, among the plurality of item n data 21a included in the prepared playlist data, the MIDI song data of the first item n data 21a in which a check mark is given to the check mark data 21a2. The MIDI song data at the position indicated by the storage path data 21a4 is read from the external storage device 10 to the reproduction area of the RAM 7 to start reproduction, and the first performance event included in the MIDI song data is read at the time of occurrence, When parameters corresponding to the read performance event are supplied to the tone generator circuit 13, digital recording is started (step S23), and MIDI song data corresponding to the last item n data 21a to which a check mark is given is digitally recorded. But When the recording is finished, the digital recording is terminated, and the digitally recorded digital audio data corresponding to the first MIDI song data to the digitally recorded digital audio data corresponding to the last MIDI song data are recorded. The file is collectively saved in the external storage device 10 in one file format (step S26).

  As described above, in this MIDI to Audio mode 2 process, among the plurality of item n data 21a included in the playlist data, the MIDI song data corresponding to all the item n data 21a to which the check mark data 21a2 is given a check mark is provided. A single digital audio file is generated and stored.

  Next, MIDI to Audio mode 2 process-2, which is a modification of the MIDI to Audio mode 2 process, will be described.

  The MIDI to Audio mode 2 process-2 is different from the MIDI to Audio mode 2 process in that adjacent audio song data is cross-fade and connected.

  FIG. 8 is a diagram showing an example of the processing result by the MIDI to Audio mode 2 processing-2. As shown in FIG. 8, a plurality of MIDI song data are reproduced one by one and digitally recorded, and the corresponding audio is recorded. When song data is generated, adjacent audio song data are connected by crossfading.

  Hereinafter, the MIDI to Audio mode 2 process-2 executed by the automatic performance data processing apparatus of the present embodiment will be described in detail with reference to FIGS.

  FIG. 9 is a diagram visually showing the MIDI to Audio mode 2 process-2, and FIG. 10 is a flowchart showing the procedure of the MIDI to Audio mode 2 process-2.

  In FIG. 9 and FIG. 10, first, as in the MIDI to Audio mode 2 process, the first item in which the check mark data 21a2 is given the check mark among the plurality of item n data 21a included in the prepared playlist data. The MIDI song data at the position indicated by the MIDI song data storage path data 21a4 of the item n data 21a is read from the external storage device 10 to the playback area of the RAM 7, playback is started, and the first performance included in the MIDI song data is started. When an event is read at the time of occurrence and parameters corresponding to the read performance event are supplied to the tone generator circuit 13, digital recording is started (steps S31 → S32 → S33).

  Next, when playback proceeds to the fade-out timing (step S34 → S35), the fade-out point t1 is stored in the digital audio recorder 23 ′ (step S36), and fade-out playback of MIDI song data is started (step S37). In response to this, the audio signal generated by the tone generator circuit 13 is digitally recorded by the digital audio recorder 23 '. Here, the fade-out timing is typically set before a predetermined fixed time (expressed in seconds or measures) from the end of each MIDI song data, but is based on the MIDI song data being played back. Then, an appropriate time for starting the fade-out may be automatically determined, and the determined time may be automatically set. Moreover, you may comprise so that a user can select and set favorite time.

  When the digital recording of the audio signal generated in accordance with the fade-out reproduction is finished (reproduction of the performance event at the end of the MIDI song data is finished), the digital recording by the digital audio recorder 23 'is stopped and the digital recording is performed. The next digital recording start position by the audio recorder 23 'is set to the stored fade-out point t1 from the current recording position t2, and the digital audio data from the position t1 to the position t2 and the audio signal output from the sound source circuit 13 are set. Is started (step S38 → S39).

  Next, among the plurality of item n data 21a included in the playlist data, the MIDI at the position indicated by the MIDI song data storage path data 21a4 of the next item n data 21a to which the check mark data 21a2 is given a check mark is provided. The song data is read from the external storage device 10 to the reproduction area of the RAM 7, fade-in reproduction is started, and the corresponding parameters are supplied to the tone generator circuit 13 (step S40).

  In response to this, the tone generator circuit 13 generates an audio signal whose volume gradually increases from silence and supplies it to the digital audio recorder 23 '. At the same time, in the digital audio recorder 23', it generates the first MIDI song data. Correspondingly, digital audio data (data being faded out) from position t1 to position t2 is reproduced from the digital audio song data generated by digital recording and supplied from the sound source circuit 13 with this digital audio data. The audio signal (the signal being faded in) is merge-recorded. Note that when the playback proceeds past the position t2, the playback of the digital audio data by the digital audio recorder 23 'stops, so that the normal digital recording is resumed.

  Even without such a merge recording, the tone generator circuit has a number of sound generation circuits that can sufficiently sound the two MIDI song data reproduced simultaneously in the crossfade portion, and two MIDI Digital audio with the same cross-fade process if it is an automatic performance device that has a number of tracks that can play song data at the same time and that can play two MIDI song data at different tempos Song data can be obtained. However, such a tone generator circuit and automatic performance device are expensive. In order to prevent such a problem from occurring, cross-fade of adjacent digital audio song data is realized using merge recording.

  The above processing is performed up to the MIDI song data corresponding to the last item n data 21a to which a check mark is given, and when the digital recording for the last MIDI song data is completed, the digital recording by the digital audio recorder 23 'is stopped. From the digital audio data digitally recorded corresponding to the first MIDI song data to the digital audio data digitally recorded corresponding to the last MIDI song data, the file is stored in the external storage device 10 in one file format. Save (step S42).

  As described above, in the MIDI to AUDIO mode 2 process-2, a joint between two audio data corresponding to two adjacent automatic performance data can be smoothed. Also, a part of two audio data corresponding to two adjacent automatic performance data can be overlapped without increasing the sound generation channel of the sound source or the number of tracks of the automatic performance data.

  Next, a MIDI to Audio mode 2 process-3, which is still another modification of the MIDI to Audio mode 2 process, will be described.

  When the MIDI to Audio mode 2 process-2 connects adjacent digital audio song data by crossfading, the digital audio data of one digital audio song data is generated by the output from the tone generator circuit 13, and the other digital audio song data is generated. Digital audio data is generated by reproduction by the digital audio recorder 23 ', and both the digital audio data are merge-recorded. On the other hand, as shown in FIGS. All the MIDI song data to be recorded are reproduced one by one and digitally recorded to create individual temporary files for each digital audio song data (step S51), and the adjacent digital audio is recorded. A temporary file of song data is reproduced using two playback tracks of the digital audio recorder, and the result of merge processing (not merge recording) at the fade-out point is written to the recording track (step S53). Yes.

  As can be seen by comparing the flowchart of FIG. 12 with the flowchart of FIG. 10, the MIDI to Audio mode 2 process-3 is configured by changing a part of the MIDI to Audio mode 2 process-2. Since the contents of the change can be understood by looking at the flowchart of FIG. 12, the description thereof is omitted.

  As described above, in the MIDI to AUDIO mode 2 process-3, a joint between two audio data corresponding to two adjacent automatic performance data can be smoothed. Also, a part of two audio data corresponding to two adjacent automatic performance data can be overlapped without increasing the sound generation channel of the sound source or the number of tracks of the automatic performance data.

  In the above MIDI to AUDIO mode 2 processing-2 and 3, the MIDI song data to be processed is (partial) MIDI song data described in the playlist data 21. However, the MIDI to AUDIO mode 2 processing-2 and 3 are mainly characterized in that two digital audio song data generated corresponding to two adjacent MIDI song data are crossfade and connected. There is no necessity to determine the MIDI song data on which the audio song data is based on the playlist data 21. Therefore, in MIDI to AUDIO mode 2 processing-2 and 3, for example, MIDI song data selected by the user may be the target of processing regardless of the playlist data 21.

  In the present embodiment, the MIDI song data to be subjected to the MIDI to AUDIO processing is not all the MIDI song data instructed to be reproduced by the playlist data 21, but a check mark is given to the check mark data 21a2. However, the present invention is not limited to this, and all MIDI song data for which playback is instructed by the playlist data 21 may be the target of MIDI to AUDIO processing.

  Furthermore, in this embodiment, MIDI song data (typically composed of standard MIDI files) is adopted as automatic performance data, but this is not restrictive, and each manufacturer's unique sequence data, automatic accompaniment data, and incoming calls are received. Any data string may be adopted as long as it is a data string that drives a sound source, such as melody data and karaoke data.

It goes without saying that the object of the present invention can also be achieved by reading and executing the code.

  In this case, the program code itself read from the storage medium realizes the novel function of the present invention, and the program code and the storage medium storing the program code constitute the present invention.
