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

  FIG. 1 is a block diagram showing a schematic configuration of a music apparatus 100 according to an embodiment of the present invention.

  As shown in the figure, the music apparatus 100 collects surrounding sounds, converts an analog sound signal obtained by collecting the sound into a digital sound signal (hereinafter referred to as “acoustic data”), and inputs the sound. An input unit 101, a display / operation interface (I / F) 102 for displaying and inputting various information, a CPU 103 that controls the entire apparatus, a control program executed by the CPU 103, various table data, and the like are stored.

Communication interface (I / F) 106 for transmitting / receiving data to / from a computer 500, etc., and audio data It converted to log the acoustic signal, and a the sound output section 107 for outputting to the outside further converted into sound.

  The components 101 to 107 are connected to each other via a bus 108, and a communication network 200 is connected to the communication I / F 106.

  The acoustic input unit 101 includes a sound collection microphone, an amplifier, an ADC (analog-to-digital converter), and the like. The acoustic data input from the acoustic input unit 101 is supplied to the RAM 105 through the bus 108 and temporarily stored in a buffer memory (see FIG. 3) provided in the RAM 105. Here, the sound input from the sound input unit 101 may be any kind of sound as long as it is a sound. For example, when a musical instrument performance sound or something nearby is hit or rubbed. Examples include sounds that are generated, singing voices, and animal calls.

  The display / operation I / F 102 includes a liquid crystal display (LCD) and a light emitting diode (LED) as a display, and a plurality of switches (SW) as input operators. FIG. 2 is a diagram illustrating a specific configuration example of the display / operation I / F 102. As shown in the figure, the display / operation I / F 102 displays a small LCD 102a that displays a tempo value defined in beats per minute (BPM), and the currently set tempo by the length of the blinking interval. LED 102b to be turned on and whether or not each store clip stored (stored) in each of the four areas (areas 1 to 4) provided in the store memory (see FIG. 3) is being lit (playing back) / LEDs 102c1 to 102c4 to be displayed in the off state (stopped), tempo up / down (BPM) SWs 102d1 and 102d2 for instructing “fast / slow tempo”, and clips stored in the clip memory (see FIG. 3) The store (STORE) SW 102e can be instructed to toggle playback / stop of each store clip. And a such clip (CLIP) 1~4SW102f1~102f4.

  Returning to FIG. 1, the CPU 103 includes a built-in timer. In the present embodiment, the built-in timer is used to measure the interrupt interval, which is the activation interval of the interrupt processing (see FIG. 6), but of course, it is also used to measure other times such as the blinking interval of the LED 102b.

  The RAM 105 is provided with at least a buffer memory 105a, a clip memory 105b, and a store memory 105c. The buffer memory 105a has a capacity capable of storing, for example, four beats of the sound data output from the sound input unit 101. However, since the time length of one beat varies depending on the tempo, the buffer memory 105a has a sufficient capacity to store acoustic data for the four beats even when the time length is designated as the longest. . The clip memory 105b includes a memory area (hereinafter referred to as “clip memories A to E”) that can store five pieces of acoustic data (hereinafter referred to as “clips”) for four beats stored in the buffer memory 105a. . The store memory 105c has four areas (areas 1 to 4) as described above, and stores four of the five clips stored in the clip memory 105b. In this embodiment, for convenience of explanation, it is assumed that four beats correspond to one measure, but this number of beats can be arbitrarily selected. The clip is sound data for one bar.

  The RAM 105 may be a volatile memory as usual, but is not limited thereto, and may be a nonvolatile memory such as a flash memory. When the flash memory is adopted, the contents and contents may be rewritten by storing the program and data stored in the ROM 104 in the flash memory.

  The sound output unit 107 includes a DAC (digital-to-analog converter), an amplifier, a speaker, and the like. In this embodiment, the sound output unit 107 converts the sound data generated by overlapping (looping) and reproducing the clip stored in the clip memory 105b (the store memory 105c may be added) into an analog sound signal. Convert, and further convert to sound and output to the outside.

  Since the present invention can be realized only by the music apparatus 100, the one used in cooperation with the music apparatus 100, that is, in the configuration example of FIG. 1, the communication I / F 106, the communication network 200, the server 300, and other music apparatuses 400 are used. And PC 500 can be omitted. For this reason, each block 106, 200, 300, 400 and 500 is represented by a broken line. I will not explain any more that can be omitted.

  The music apparatus 100 is configured as a single apparatus in the present embodiment, but is not limited thereto, and may be configured by combining a plurality of apparatuses. For example, an input / output device including the sound input unit 101 and the sound output unit 107 and a cradle including the CPU 103, the ROM 104, the RAM 105, and the communication I / F 106 are connected to each other by an arbitrary connection method such as wireless or wired. An embodiment is conceivable.

  The control process executed by the music apparatus 100 configured as described above will be described first with reference to FIG. 3, and then described in detail with reference to FIGS.

FIG. 3 is a block diagram showing a functional configuration of the music apparatus 100. In FIG. 3, the control unit 100a is constituted by a CPU 103, a ROM 104, and a RAM 105. The control unit 100a is mainly composed of
Clip memory writing process: a process of reading the stored clip and writing it sequentially to any one of the clip memories A to E each time the clip is stored in the buffer memory 105a;
First loop reproduction start processing: processing for starting loop reproduction of clips written to the clip memories A to E by the clip memory writing processing;
Store memory write processing: Four of the five clips stored in the clip memories A to E in response to the press of the store SW 102e (in the case of less than four as will be described later in detail of control processing) Read out and write to the store memory 105c;
Second loop reproduction start process: Among the four store clips stored in the store memory 105c by the store memory write process, the loop reproduction of the store clip designated in response to the pressing of the clips 1 to 4SWs 102f1 to 102f4 is started. processing;
Second loop playback stop process: A process of stopping loop playback of a store clip whose loop playback has been started by the second loop playback start process in response to re-pressing of the corresponding SW among the clips 1 to 4SWs 102f1 to 102f4;
Execute.

  Each clip that is being played back, including the clip for which loop playback has been started by the first loop playback start process, is added (mixed) by the adder 100b and supplied to the sound output unit 107 through the adder 100c. Note that a total of five clips are stored in the clip memories A to E, so that the five clips are simultaneously played and mixed. Of the five clips, one is faded in and one is faded out. Since it is played back, the number of clips played back simultaneously is substantially four.

  As a result of the store memory writing process, four of the five clips are stored as store clips in the store memory 105c. When any one of the clips 1 to 4SWs 102f1 to 102f4 is pressed in this state, the first loop playback is performed. Both processes are executed by adding the second loop reproduction start process to the start process. The store clip whose loop playback has been started by the second loop playback start process is added to the output from the adder 100 b by the adder 100 c and supplied to the sound output unit 107. At this time, the adder 100b is controlled so as to be supplied from the clip memory 105b with a clip reduced by the number of store clips whose loop playback has been started by the second loop playback start process. The five clips (substantially four as described above) are output.

  As described above, in this embodiment, the user simply generates sound around the sound input unit 101, and the sound data corresponding to the sound is automatically input, and is clipped for each preset time length. Since a plurality of clips are held and each clip is overlapped for loop reproduction, the input acoustic signal can be easily overlapped for each preset time length and easily loop reproduced.

  Next, this control process will be described in detail.

  FIG. 5 is a flowchart showing a procedure of a main routine executed by the music apparatus 100, particularly the CPU 103. This main routine is activated when the power to the music apparatus 100 is turned on.

  When this main routine is started, the startup process (steps S1 and S2) is executed once, and then a standby state is entered until any SW is pressed by the SW event detection process (steps S3 and S4). . When a SW event is detected, the process corresponding to the pressed SW that is the cause of the SW event (steps S5 to S11) is executed, and then the process returns to the SW event detection process again to create a new SW event. It will be in the standby state. Thereafter, these processes are repeatedly executed as appropriate until the power is turned off.

  In the startup process, first, the CPU 103 executes an initialization process (step S1). In this initialization process, after clearing the RAM 105, the CPU 103 stores an initial value (eg, “120”) of the BPM in a BPM storage area (not shown) secured at a predetermined position in the RAM 105, and stores the BPM. Based on the BPM value stored in the area, an interrupt interval for interrupt processing (described later) is calculated, and the calculated interrupt interval is stored in an interrupt interval storage area (not shown) secured at a predetermined position in the RAM 105.

  Since “120” is stored in the BPM storage area now, interrupt interval = time of one measure = 4 beats × time per beat (seconds) = 4 × (60 ÷ 120) = 2 (seconds) And “2” is stored in the interrupt interval storage area. An interrupt interval is not calculated, and a table in which an interrupt interval is associated with each BPM value is provided. An interrupt interval corresponding to the BPM value stored in the BPM storage area is read from the table, and an interrupt interval storage area is read out. You may make it memorize.

  Next, the CPU 103 starts clip and output processing (step S2). In this clip-and-output process, the CPU 103 permits timer interruption and starts measuring the interruption interval by the built-in timer. The built-in timer compares its own clock time with the interrupt interval stored in the interrupt interval storage area, and if they match, outputs an interrupt signal and resets the clock time. The CPU 103 starts an interrupt process every time an interrupt signal is output.

  FIG. 6 is a flowchart showing the procedure of this interrupt process. This interrupt process is started and executed every time corresponding to one bar based on the time measurement time and the interrupt interval as described above. In this interrupt process, the CPU 103 executes the clip memory write process (steps S21 and S22) and the first loop reproduction start process (steps S22 and S23).

  When this interrupt process ends, the CPU 103 returns to the process of the main routine executed immediately before the interrupt process is activated.

Returning to FIG. 5, when the SW event is detected by the SW event detection process, the CPU 103 branches to the process according to the detected SW event as follows. That is,
Press event of the store SW 102e: the store memory write process (step S5)
Press event of clips 1 to 4 SW102f1 to 102f4: one of the second loop reproduction start process (steps S7 and S8) and the second loop reproduction stop process (steps S9 and S10) Tempo up / down (BPM) SW102d1, 102d2 pressing event: BPM value update processing (step S11)
Branch like this.

  In the BPM value update process, the CPU 103 updates the stored value in the BPM storage area with the BPM value instructed to change by the tempo up / down (BPM) SWs 102d1 and 102d2, and changes the BPM value to the BPM value as described above. Based on the calculated interrupt interval, the interrupt value is updated based on the calculated interrupt interval. When the BMP value update process is executed and the BPM value is changed, the CPU 103 temporarily stops the process performed by the interrupt process, that is, the clip memory write process and the first loop reproduction start process, and the buffer memory 105a and After clearing the clip memory 105b, the interrupt processing is restarted according to the interrupt interval after the change. Note that the reason for adopting such processing is solely for the simplification of the control processing. Even if the BPM value is changed without using such processing, the processing performed in the interrupt processing is continued as it is. It can also be done. However, in this case, in addition to the flowcharts of FIG. 5 and FIG. 6, processing such as time stretching and resampling is performed on the playback target clip (or store clip) so that the pitch does not fluctuate. In the above, it is desirable to perform control so that playback is performed at the playback time corresponding to the changed BPM value (time for one bar after the BPM value change).

  Hereinafter, the clip memory write process, the first loop reproduction start process, the store memory write process, the second loop reproduction start process, and the second loop reproduction stop process will be described based on the specific example of FIG.

  FIG. 4 is a diagram for explaining a control process executed by the music apparatus 100. FIG. 4A is a diagram for explaining a control process when the second loop reproduction start process is not executed. FIG. 5B is a diagram for explaining the control process when the second loop reproduction start process is executed.

  In FIG. 4A, the input audio block sequence of CL1 to CL10 indicates acoustic data for one bar (= 4 beats) stored in the buffer memory 105a, that is, a clip. In the illustrated example, the clip CL1 is drawn so as to be older than the clip CL1, but here, the clip CL1 is assumed to be a clip acquired first (after the main routine is started).

  When a time length of 4 beats (= 2 seconds) has elapsed since the timer interrupt was first permitted, the interrupt process is started. In the interrupt process, first, the CPU 103 advances the process to a clip memory writing process, and acquires a clip for the immediately preceding one bar from the buffer memory 105a (step S21). Thereby, the clip CL1 is acquired. Then, the CPU 103 overwrites the contents of the oldest clip memory 105b with the acquired clip CL1 (front stage of step S22). At this time, since the clip memory 105b is in a clear state, the acquired clip CL1 is written to the clip memory A having the first writing order. When the acquired clip is written to the clip memory 105b, the current BPM value is also written along with the clip.

  Next, the CPU 103 advances the process to a first loop reproduction start process, and starts loop reproduction (after stage S22). As a result, the loop reproduction of the clip CL1 is started in parallel with the writing of the clip CL1 to the clip memory A. At this time, the clip CL1 is faded in. In the illustrated example, “fade-in playback” is represented by “★”. Then, the CPU 103 fades out the reproduction of the second oldest clip (the clip held in the clip memory whose contents are overwritten by the acquired clip in the interrupt processing at the next timing) (step S23), and then interrupts. The process ends. Now, since only one clip CL1 is stored in the clip memory 105b, the process of step S23 is not substantially performed.

  When the interrupt process is completed, the process returns to the main routine, but since no SW is pressed, a standby state for the SW event is entered (step S3). In this standby state, since the built-in timer measures the next interrupt interval, the interrupt process is started again, and the clip memory write process and the first loop reproduction start process are executed. As a result, the clip CL2 is written into the clip memory B and the clip CL2 is faded-in reproduced, while the clip CL1 is normally reproduced from the beginning. That is, the clip CL1 is the first loop reproduction. Note that the fade-in reproduction process (including the normal reproduction and the fade-out reproduction) after the start of the loop reproduction is instructed is performed in an interrupt process different from the interrupt process of FIG. Shall.

  When such a process is repeatedly executed and the fifth interrupt process is started, the clip CL5 is written into the clip memory E, the clip CL5 is faded-in and the clips CL2 to CL4 are normally reproduced. The clip CL1 is faded out by the process of step S23. In the illustrated example, “fade-out playback” is represented by “☆”.

  When the store SW 102e is pressed at time t1 during the period until the next interrupt process is activated, the CPU 103 advances the process to the store memory write process (step S4). In this store memory write process, the CPU 103 writes the contents of the clip memory 105b in the non-reproducing area among the four areas in the store memory 105c. At time t1 (immediately before), the store memory 105c is in a clear state, and no store clip is stored in any region, so all the regions 1 to 4 are non-reproducing regions. For this reason, the contents of the clip memory 105b are written in all the areas 1 to 4 of the store memory 105c. However, as described above, the clip memory 105b includes five areas of the clip memories A to E, and one clip is stored in each of the five areas, so four of these are selected, In other words, any one clip is excluded and written to the store memory 105c. In the present embodiment, the fade-in playback, that is, the clip CL5 is excluded. This is because it is presumed that the user wants to store in the store memory 105c what has been loop-played once or more. As a result, the clips CL1 to CL4 are stored in the areas 1 to 4 of the store memory 105c, respectively. Of course, the present invention is not limited to this.

  Thereafter, when the seventh interrupt process is started, the area of the clip memory 105b that holds the oldest clip is the clip memory B, so the acquired clip CL7 is written (overwritten) in the clip memory B, Fade-in playback starts. Since the second oldest clip is the clip CL3 of the clip memory C, fade-out reproduction of the clip CL3 is started. When the store SW 102e is pressed at time t2, fade-in playback is being performed among the clips CL3 to CL7 stored in the clip memory 105b in the same manner as the processing corresponding to the press of the store SW 102e at time t1. Four clips excluding the current clip CL7 are written to the store memory 105c.

  In this way, the clipped sound data is loop-reproduced four times and mixed with other clips and output.

  Next, in FIG. 4B, an example in which the store SW 102e, the clip 1SW 102f1, and the clip 3SW 102f3 are pressed at time t1, the store SW 102e is pressed at time t2, and the clip 1SW 102f1 is pressed at time t3. Show.

  The process when the store SW 102e is pressed at time t1 in FIG. 4B is the same as the process when the store SW 102e is pressed at time t1 in FIG. Omitted.

  When the clip 1SW 102f1 is pressed subsequent to the store SW 102e, the CPU 103 advances the process to a second loop reproduction start process. In this second loop playback start process, first, the CPU 103 starts fade-in playback of the store clip in the area corresponding to the SW number instructed to start playback among the areas 1 to 4 in the store memory 105c ( Step S7). As a result, fade-in playback of the store clip (clip CL1) stored in area 1 of the store memory 105c is started. Next, the CPU 103 stops writing to the area holding the oldest clip in the clip memory 105b (in this case, the clip memory A), and fades out the reproduction of the clip (in this case, the clip CL1). (Step S8). When writing to the clip memory A is stopped, when the next interrupt processing is started, the acquired clip CL6 is an area (clip memory B) that holds the oldest clip in the writable clip memory 105b. ) Will be written. Since the clip memory B is an area where the clip is overwritten next, fade-out reproduction of the clip CL2 of the clip memory B is started. As a result, the number of clip loops decreases from “4” to “3”.

  When the clip 3SW 102f3 is pressed after the clip 1SW 102f1, the same processing as that when the clip 1SW 102f1 is pressed is executed. As a result, fade-in reproduction of the clip CL3 stored in the area 3 of the store memory 105c is started. Further, the writing to the clip memory B is stopped, and the clip memory C of the writable clip memory 105b becomes the area where the clip is overwritten next, the fade-out playback of the clip CL3 of the clip memory C is started, and the clip loop The number of times decreases from “3” to “2”. Therefore, when the next interrupt process is started, fade-in playback starts after the clip CL3 of the clip memory C holding the oldest clip in the writable clip memory 105b is overwritten with the acquired clip CL6. Then, fade-out reproduction of the clip CL4 of the oldest clip memory D is started.

 When playback of a store clip in the store memory 105c is started, the BPM value stored accompanying the store clip may be different from the current BPM value. At this time, the process described above for the case where the BPM value is changed while the clip in the clip memory 105b is being played, that is, the pitch of the store clip is not changed by performing processes such as time stretching and resampling. Then, control is performed so that playback is performed in the playback time corresponding to the current BPM value (time for one bar after the BPM value is changed).

  Next, when the store SW 102e is pressed at time t2 as in the case of time t2 in FIG. 4A, the CPU 103 advances the process to the store memory write process (step S5). At this time, since the clips CL1 and CL3 respectively stored in the areas 1 and 3 of the store memory 105c are being reproduced, the two areas excluding the clip CL7 being fade-in reproduced in the non-reproducing areas 2 and 4 Clips CL5 and CL6 are written.

  Next, at time t3, when the clip 1SW 102f1 is pressed, the store clip (clip CL1) in the area 1 of the store memory 105c is currently being loop-reproduced, so the CPU 103 performs the second loop reproduction stop process. Proceed to In the second loop playback stop process, first, the CPU 103 starts fade-out playback of the store clip in the area corresponding to the SW number instructed to stop playback among the areas 1 to 4 in the store memory 105c (step S1). S9). Thereby, fade-out reproduction of the store clip (clip CL1) stored in the area 1 of the store memory 105c is started.

  Next, the CPU 103 switches the clip held in the clip memory 105b in the interrupt processing to the fade-in playback, and further switches to one of the areas of the clip memory 105b in which the writing has been stopped. Is resumed (step S10). As a result, the number of clip loops increases from “2” to “3”.

  At time t3, the clip that is faded out is the clip CL6 of the clip memory C, and therefore the clip CL6 is switched to fade-in reproduction. In the illustrated example, “switching from fade-out playback to fade-in playback” is represented by “♦”.

  Note that, as exemplified at time t1 in FIG. 4B, among the clips held in each area of the clip memory 105b, when there are a plurality of fade-out playback clips, the youngest clip (in the case of time t1). If so, the clip CL3) of the clip memory C is switched to fade-in playback.

  At time t2, the areas where writing was stopped are the clip memories A and B. Thus, when there are a plurality of areas where writing can be resumed, writing to any one is resumed. The selection of the area where writing is to be resumed may be performed using any method, for example, the oldest area where writing has been stopped, or selection based on a preset priority order.

  In the state where all the store clips in the areas 1 to 4 in the store memory 105c are being reproduced, only one of the areas A to E in the clip memory 105b can be written, but the contents of the buffer memory 105a Are sequentially overwritten in this one area. For this reason, there is no clip to be played back in the clip memory 105b, and the number of loops is “0”. In this case, the CPU 103 executes only the clip memory writing process (the previous stage of steps S21 and S22) in the interrupt process of FIG.

  As is apparent from the above description, in the present embodiment, the number of clip loops is defined based on the number of writable clip memory 105b areas (number of loops = number of writable areas-1). Instead, a parameter that defines the number of loops may be provided, and the number of loops of each clip may be controlled by appropriately setting and updating the value of the parameter.

  In this embodiment, the fade time in the fade-in reproduction process and the fade-out reproduction process is not particularly mentioned, but may be appropriately selected between 1 to 4 beats. The selected value may be fixed or may be changeable by the user.

  Furthermore, in the present embodiment, the present invention is realized only by the music apparatus 100, but the present invention is not limited to this, and other music apparatuses (the server 300 or the other music apparatus 400 are connected via the communication I / F 106). Alternatively, the stored data may be transmitted to the PC 500), or the data may be received from another music device to perform a music session. In this case, the store memory 105c is expanded and a memory for holding the received clip is added. Of course, the stored data may be written to any storage medium.

  Further, various effectors such as echo, reverb, chorus, distortion may be provided. A plurality of effectors may be provided, and different effectors may be applied to each of the clip memories A to E and the areas 1 to 4 of the store memory 105c.
