Description

  The present invention relates to a recording / reproducing apparatus, and more particularly to a recording / reproducing apparatus having a count-in function.

  A digital recorder may have a function called a count-in function. This count-in function counts a designated number of metronome sounds before starting recording or reproduction, and performs recording or reproduction at a timing when the count becomes zero. In the case of a recording / reproducing apparatus that can reproduce a rhythm pattern at the same time as recording, the rhythm pattern is generally reproduced at the same time as recording after the count-in.

  FIG. 6 shows a timing chart of the conventional apparatus. This is a case where the time signature is 4/4, and “−4” is set as the count value. Here, a minus sign means that counting is performed prior to the start of rhythm playback and recording. Counts only 4 beats, starts recording at the timing when the count is completed, and starts rhythm playback. When the performance is started after a pause of 4 beats, the performance sound is recorded together with the rhythm playback sound.

  The following Patent Document 1 discloses a count-in function for starting a record after counting a predetermined number of beats.

  Patent Document 2 prohibits starting count-in after pressing the record button, and sending sound generation instruction information generated by the performance operator to the MIDIout terminal of the electronic musical instrument during count-in. Is disclosed.

  However, when the start timing of a song to be played is weak, there is a problem that cannot be handled by a conventional recording / playback apparatus. Here, weakness means that a melody or song starts with a weak beat. On the other hand, violence means starting with a strong beat, that is, the first beat.

  FIG. 7 shows an example in which the start timing of a song to be played is weak. In the figure, the timing indicated by reference numeral 100 is a weak start timing, and the performance is started from here. However, since the conventional apparatus starts recording and rhythm playback at the timing after the count-in as shown in FIG. 6, even if the performance is started with weakness, the performance sound cannot be recorded.

  On the other hand, as shown in FIG. 8, it is conceivable that the count-in start timing is shifted so that the count-in is completed and the recording is started before the performance is started with a weak start. Since the rhythm playback starts at the same time as the start, there is a disadvantage that an unnecessary rhythm playback sound is recorded between the start of recording and the start of performance.

  It is an object of the present invention to provide a recording / reproducing apparatus with a count-in function that can cope with a melody or a song that starts with weakness.

The present invention is a recording / reproducing apparatus having a count-in function for outputting a count sound corresponding to a set count value, wherein a setting means capable of setting a positive value as the count value, and a positive value as the count value Is set to start recording at a predetermined timing and start playback of the rhythm sound after the recording start timing and when the counts set by the count value are completed. and means, and switching means for switching whether to record a count sound and / or the rhythm sound possess, the control unit, when said switching means is set to record, the at the predetermined timing The count sound is mixed with the input sound to start recording, and the rhythm sound is mixed with the input sound and the mixing sound when the count value is counted. Characterized in that it start recording.

Further, the present invention is a recording / reproducing apparatus having a count-in function for outputting a count sound corresponding to a set count value, and setting means capable of setting a positive value as a count value in addition to a negative value; When a negative value is set as the count value, recording is started at the timing when counting for the amount set by the count value is completed and rhythm sound reproduction is started, and a positive value is set as the count value. Is set to start recording at a predetermined timing and start playback of the rhythm sound after the recording start timing and when the counts set by the count value are completed. means and, have a switching means for switching whether to record a count sound and / or the rhythm sound, the control means, said switching means When the recording is set, the count sound is mixed with the input sound at the predetermined timing to start recording, and the rhythm sound is mixed with the input sound at the timing when the count value is completed. It is characterized by starting .

  According to the present invention, it is possible to record in the case of a melody or a song that starts with weakness.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows an external view of a recording / reproducing apparatus (or digital recorder) 10 in the present embodiment. The recording / reproducing apparatus 10 has a count-in function and a rhythm reproduction function. The recording / playback apparatus 10 includes a liquid crystal display (LCD) 12, a recording key 14 that is operated during recording, a playback key 16 that is operated when playing a recorded file, a stop key 18 that is operated when recording or playback is stopped, and a setting. For example, a key 20 that is operated when displaying a screen for performing the above and the like on the LCD 12, and a dial 22 that is operated when changing the setting. The LCD 12 displays various setting screens and recording / playback status.

  FIG. 2 shows a screen example of the LCD 12 at the time of setting. Rhythm tempo (TEMPO), pattern (PATTERN), count-in (COUNT IN), and count recording (COUNT REC) are set. Count recording is an item for setting whether or not to record a count sound. If ON, the count sound is recorded. If OFF, the count sound is not recorded. The count-in can be set to a negative value and a positive value. For example, any of -4, -3, -2, -1, 0, +1, +2, +3, and +4 can be selected and set as the count-in. When the count-in value is negative, when the recording key 14 is operated, a count sound is generated for the count-in number, and when the count reaches zero, recording is started and rhythm reproduction is started. For example, when “−4” is set as the count-in value, recording is started after four beats are counted, and rhythm reproduction is started as in the conventional case. On the other hand, when the count-in value is positive, the count is started after the recording is started, and the rhythm reproduction is started when the count becomes zero. In other words, when the count-in value is negative, the count zero means the recording start timing and the rhythm playback start timing, whereas when the count-in value is positive, the count zero means only the rhythm playback start timing. The recording start timing is irrelevant.

  FIG. 3 shows a configuration block diagram of the recording / reproducing apparatus 10. Operation signals from various switches 32 including the recording key 14 and the like and the wheel 30 including the key 22 and the like are supplied to the CPU 34. The CPU 34 displays various setting screens and recording / playback information on the LCD 12.

  During recording, an external audio signal (performance sound) is input from an input terminal (AUDIO IN), encoded by a codec (CODEC), and supplied to the CPU 34. The CPU 34 writes the input audio data to the memory card 38 inserted in the card socket 36. The CPU 34 may store audio data in a flash memory built in the apparatus. The CPU 34 operates with the clock supplied from the system clock 42, and uses the RAM 46 as a working memory to record or reproduce audio data according to a program stored in the ROM 44.

  During reproduction, audio data is read from the memory card 38 or the built-in flash memory, demodulated by a codec (CODEC), and output from an output terminal (AUDIO OUT). At the time of counting sound reproduction and rhythm sound reproduction, the sound source of the count sound and the sound source of the rhythm sound stored in advance in the flash memory are read and reproduced. The count sound is, for example, “click”, “click”, and the rhythm sound is, for example, a drum sound. Predetermined power is supplied from the power supply circuit 48 to the CPU 34, the codec 40, and the like.

  FIG. 4 shows a functional block diagram of the CPU 34. The CPU 34 includes a UI (user interface) control unit 34a, an audio recording processing unit 34b, a rhythm sequence processing unit 34c, a rhythm sound source processing unit 34d, and a mixing processing unit 34e.

  The UI control unit 34a supplies a tempo, a pattern, and a count-in value to the rhythm sequence processing unit 34c in response to an operation signal from the wheel 30 or the switch 32. Further, a playback start and stop signal is supplied to the rhythm sequence processing unit 34c. Further, a recording start / stop signal is supplied to the audio recording processing unit 34b.

  The rhythm sequence processing unit 34c instructs the rhythm sound source processing unit 34d to generate rhythm based on the set tempo, pattern, start signal, and stop signal. Further, the rhythm sound source processing 34d is instructed to generate a count sound based on the set count number. The rhythm sequence processing unit 34c supplies a recording switching signal to the mixing processing unit 34e. The recording switching signal is used to switch whether to record a rhythm sound or a count sound, that is, whether to record a rhythm sound or a count sound mixed with an input sound, or to perform only a reproduction. When the count recording (COUNT REC) in FIG. 2 is turned ON, the count sound is mixed and recorded. When the count recording is turned OFF, only the count sound is reproduced. Further, the rhythm sequence processing unit 34c supplies a recording start signal to the audio recording processing unit 34b.

  The rhythm sound source processing unit 34d reproduces the rhythm sound and supplies it to the mixing processing unit 34e. Further, a count sound is generated and supplied to the mixing processing unit 34e. The count sound is, for example, “click” or “click” of a metronome.

  The mixing processing unit 34e switches between mixing recording and reproduction in accordance with a recording switching signal from the rhythm sequence processing unit 34c. In the case of mixing recording, the audio data from the codec 40 and the rhythm audio data from the rhythm sound source processing unit 34d are mixed and supplied to the audio recording processing unit 34b. In the case of reproduction, the rhythm sound data or the count sound data from the rhythm sound source processing unit 34d is supplied to the codec 40 without being mixed and demodulated to output the sound. The mixing processing unit 34e can reproduce the count audio data and mix the rhythm audio data with the input audio data and supply the audio data to the audio recording processing unit 34b in response to the recording switching signal. Both the count sound data and the rhythm sound can be mixed into the input sound data.

  In such a configuration, when the user sets the count-in value to -4, for example, the UI control unit 34a supplies tempo and count value data to the rhythm sequence processing unit 34c prior to recording. When the user operates the recording key 14, the UI control unit 34a supplies a rhythm start signal to the rhythm sequence processing unit 34c. The rhythm sequence processing unit 34c supplies a count sound generation instruction to the rhythm sound source processing unit 34d in response to the rhythm start signal. The rhythm sound source processing unit 34d generates count sound data and supplies it to the mixing processing unit 34e. The mixing processing unit 34e supplies the count sound data to the codec 40 and outputs the count sound. When the count becomes zero (when four beats have been counted), the rhythm sequence processing unit 34c instructs the rhythm sound source processing unit 34d to generate a rhythm sound and starts recording to the audio recording processing unit 34b. (Recording start) is instructed. In addition, the mixing processing unit 34e is instructed to switch to mixing. The rhythm sound source processing unit 34d reads out the rhythm sound data stored in advance in the built-in flash memory or stored in the memory card 38, and supplies it to the mixing processing unit 34e. The mixing processing unit 34e mixes the input sound data and the rhythm sound data and supplies them to the sound recording processing unit 34b. The voice recording processing unit 34b records the mixed input voice data and rhythm voice data in accordance with the recording start signal.

  On the other hand, when the user sets the count-in value to +4, for example, the UI control unit 34a supplies tempo and count value data to the rhythm sequence processing unit 34c prior to recording. When the user operates the recording key 14, the UI control unit 34a supplies a rhythm start signal to the rhythm sequence processing unit 34c and supplies a recording start instruction to the audio recording processing unit 34b. The voice recording processing unit 34b starts recording in response to the recording start instruction. On the other hand, the rhythm sequence processing unit 34c supplies a count sound generation instruction to the rhythm sound source processing unit 34d. The rhythm sound source processing unit 34d generates count sound data and supplies it to the mixing processing unit 34e. The mixing processing unit 34e supplies the count sound data to the codec 40 and outputs the count sound. When the count becomes zero (when four beats are counted), the rhythm sequence processing unit 34c instructs the rhythm sound source processing unit 34d to generate a rhythm sound.

  When COUNT REC is OFF, the mixing processing unit 34e only supplies the count sound data to the codec 40 in response to the control signal from the rhythm sequence processing unit 34c. At the timing when the count becomes zero, the rhythm sound data is supplied to the codec 40, mixed with the input sound, and supplied to the sound recording processing unit 34b.

  When COUNT REC is ON, the mixing processing unit 34e supplies the count sound data to the codec 40 and also to the audio recording processing unit 34b according to the control signal from the rhythm sequence processing unit 34c.

  FIG. 5 shows a timing chart of the present embodiment. This is a case where the count-in value is set to +4. Recording starts when the recording key 14 is operated. Then, a count sound is output, and after counting 4 beats, the count becomes zero and rhythm reproduction is started. On the other hand, in the case of weak occurrence, the performance is started at a count value of, for example, the third beat. At this time, since the recording has already been started, the performance sound is surely recorded. Since the rhythm playback starts when the count reaches zero, the rhythm sound and the performance sound are mixed and recorded at this timing.

  Compared with FIG. 5 showing the timing chart of this embodiment and FIG. 6 or FIG. 8 showing the timing chart of the conventional apparatus, the effect of this embodiment will be apparent. That is, in FIG. 6, even if the performance is started with a weak start, the recording is not started, so the beginning portion of the performance is not recorded. In FIG. 8, although the recording is started, the rhythm sound is started at the same time, so the rhythm sound is recorded before the performance start timing. On the other hand, in FIG. 5, since the recording is started before the performance is started, the beginning portion of the performance is surely recorded. Moreover, since the rhythm sound is reproduced when the count reaches zero, an unnecessary rhythm sound is not recorded before the performance starts. Therefore, as shown in FIG. 7, desired recording can be reliably performed even with a weakly tuned song.

  As described above, in this embodiment, the count-in value, that is, the count-in count value in the recording / playback apparatus having the count-in function can be set not only minus but also plus, and when minus is set, As with the conventional device, recording starts at the timing when the count is zero and the count is completed, and the rhythm sound starts to be played, but if positive is set, recording starts first, and the count is zero. The rhythm playback starts at the timing when the counting is completed. When the count value is negative, the recording start timing and the rhythm sound playback start timing are synchronized. However, when the count value is positive, the recording start timing and the rhythm sound playback start timing are not synchronized. In other words, it can be said that rhythm sound reproduction is started after recording is started. By shifting the recording start timing and the rhythm sound start timing, it is possible to perform only the recording without reproducing the rhythm sound at the weak start timing. In general, the count-in function can be said to be a function that regulates the recording start timing and the rhythm sound reproduction start timing. In this embodiment, when the count value is negative, this normal function is used. When the count value is positive, the recording start timing and the rhythm sound playback start timing are separated, and the rhythm sound is used as the count-in function. It can be said that the function is changed to a function that regulates only the timing of starting sound reproduction. By separating the recording start timing and the rhythm sound playback start timing in this way, in this embodiment, it is possible to record the performance sound even during the count-in operation, and regardless of the recording start timing. It is possible to freely set the timing for starting the rhythm sound reproduction.

  In this embodiment, the recording start timing when the count value is positive is the timing at which the user operates the recording key 14, but this recording start timing is also the timing at which counting starts. Recording may be started after a predetermined time has elapsed by operating the recording key 14, and counting may be started simultaneously.

  In the present embodiment, both the minus and the plus can be set as the count-in value, but only the plus can be set.

  In this embodiment, minus and plus can be set as the count-in value. However, substantially the same content can be set to different names. For example, the minus of the count-in value in this embodiment is simply used as the count-in count value, and the plus of the count-in value in this embodiment is used as the count-out count value. If the count-out is defined as the time interval from the start of recording to the start of rhythm sound reproduction, this is equivalent to the count-in plus value in this embodiment, and it goes without saying that such a technique is also included in the present invention. The minus of the count-in value in the present embodiment may be the first count or the pre-count, and the plus of the count-in value in the present embodiment may be the second count or the post-count. In the present embodiment, “minus” of the count value means before recording starts, and “plus” means after recording starts.
