  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 an electronic music apparatus according to an embodiment of the present invention.

  As shown in the figure, the electronic music apparatus of the present embodiment includes a performance operator 1 including a keyboard for inputting performance data including pitch information, and a plurality of switches and knobs for inputting various types of information. , A setting operator 2 including a slider and a dial, a detection circuit 3 that detects an operation state of the performance operator 1, a detection circuit 4 that detects an operation state of the setting operator 2, and a CPU 5 that controls the entire apparatus. A ROM 6 for storing a control program executed by the CPU 5, various table data, various waveform data, various musical tone parameters, a RAM 7 for temporarily storing performance data, various input information, calculation results, and the like; For example, a display 8 having a small liquid crystal display (LCD) and a light emitting diode (LED) and the like, and various applications including the control program. A storage device 9 for storing a communication program, various music data, various data, etc., an external device (not shown), a communication interface (I / F) 10 for transmitting / receiving data to / from the external device, and a performance operator 1 A tone generator for converting input performance data, performance data obtained by reproducing any of the music data stored in the storage device 9 into a musical sound signal, and imparting various effects to the musical sound signal An effect circuit 11 and a sound system 12 such as a DAC (digital-to-analog converter), an amplifier, and a speaker that convert a musical sound signal from the sound source / effect circuit 11 into sound.

  The components 3 to 11 are connected to each other via a bus 13, and a sound system 12 is connected to the sound source / effect circuit 11.

  The storage device 9 is, for example, a storage medium such as a flexible disk (FD), a hard disk (HD), a CD-ROM, a DVD (digital versatile disc), a magneto-optical disk (MO), and a semiconductor memory, and a driving device thereof. The storage medium may be detachable from the drive device, or the storage device 9 itself may be detachable from the electronic music device of the present embodiment. Alternatively, neither the storage medium nor the storage device 9 may be detachable. The storage device 9 (the storage medium) can also store the control program executed by the CPU 5 as described above. If the control program is not stored in the ROM 6, the control program is stored in the storage device 9. By reading it into the RAM 7, the CPU 5 can be operated in the same manner as when the control program is stored in the ROM 6. In this way, control programs can be easily added and upgraded.

  As the communication I / F 10, for example, a dedicated music I / F for transmitting and receiving music signals such as MIDI (musical instrument digital interface) signals, and a general-purpose short-distance wired I / F such as USB (universal serial bus) and IEEE1394. And general-purpose network I / F such as Ethernet (registered trademark), and general-purpose short-range wireless I / F such as wireless local area network (LAN) and Bluetooth (registered trademark). In this embodiment, the USB is adopted as the communication I / F 10, but other types of I / Fs may be used instead, and other types of I / Fs may be added thereto. It may be.

  FIG. 2 is a diagram showing an example of the configuration of one of the setting operators 2 related to the present invention. 4A to 4D illustrate four operating elements 21 to 24, but only one operating element related to the present invention (referred to as slider 21 in FIG. 1A). There are three other operators 22 to 24 that can be used in place of the operator 21.

  As shown in FIG. 2A, the slider 21 is configured to be able to select any one of “CLEAR”, “REC”, “PLAY”, “PAUSE”, and “STOP”. The slider 21 is not switchable as a property of the switch unless it passes through an adjacent item. For example, it is impossible to select “CLEAR” because “REC” is skipped from the state where “PLAY” is selected, so “REC” must be selected before “CLEAR” can be selected. Don't be. In addition, it is better to provide a feel imparting structure that can receive a moderate feeling every time the item is switched so that selection of each item can be understood by touch. Specifically, it is switched with a ticking sound. This situation is the same for the other operating elements 22-24. The meaning of each selectable item such as “CLEAR” will be described later.

  FIG. 2B shows an example in which a dial type SW22 is adopted instead of the slider type SW (switch). The dial type SW 22 is configured such that an item can be selected by rotating a donut-shaped rotary operation element 22a and aligning any item with an arrow display 22b on the panel surface. The rotary operator 22a is configured to rotate only to a certain position. Specifically, it rotates only to the “CLEAR” position in the clockwise direction and rotates only to the “STOP” position in the counterclockwise direction. Thereby, the transition of the selection item becomes the same as the transition by the slider 21. Of course, it is not limited to this, and it may be turned endlessly. In this case, it is possible to change the item from “CLEAR” to “STOP” and vice versa.

  FIG. 2C shows an example in which the dial type SW 23 is adopted as in FIG. However, in the dial type SW 23, there is an arrow display on the disk-shaped rotary operation element 23a. By rotating the rotary operation element 23a and matching the arrow display to the selection item displayed on the panel surface, the item is displayed. The point to select is different. Note that the rotary operation element 23a also rotates only to the “STOP” position in the clockwise direction and only to the “CLEAR” position in the counterclockwise direction. Of course, it is not limited to this, and it may be turned endlessly.

  FIG. 2D shows an example in which the up (up) / down (down) SW 24 and the display screen 8 a of the display 8 are employed. The up / down SW 24 includes an up SW 24a and a down SW 24b. Selection items are displayed on the display screen 8a, and the user operates the up SW 24a or the down SW 24b to select the item by moving the cursor C up / down. The cursor C does not move above “CLEAR” and does not move below “STOP”. Of course, the present invention is not limited to this, and if the up SW 24a is operated while the cursor C is in the “CLEAR” position, the cursor C moves to the “STOP” position, and conversely, the cursor C moves to the “STOP” position. When the down switch 24b is operated in a certain state, the cursor C may be moved to the “CLEAR” position.

  A control process executed by the electronic music apparatus configured as described above will be described in detail with reference to FIGS.

  FIG. 3 is a flowchart showing the procedure of the main routine executed by the electronic music apparatus, particularly the CPU 5.

  This main routine mainly includes an initialization process (step S1), an operator input acceptance process (step S2), and a sound generation / recording process (step S3). This main routine is started when the electronic music apparatus is turned on. After the initialization process is executed once, the operator input acceptance process and the sound production / recording process are repeated until the power is turned off. Executed.

  In the initialization process, the CPU 5 clears the RAM 7, sets the values of various parameters to default values, starts a timer (for example, those built in the CPU 5), or starts timer interrupt processing. In order to make this happen, the timer is allowed to generate an interrupt signal.

  4A and 4B are flowcharts showing the detailed procedure of the operator input acceptance process. This manipulator input acceptance process includes a setting manipulator related process (steps S12 to S22 in FIG. 4B) executed when the setting manipulator 2 (any one of the manipulators) is operated, and a performance manipulator. 1 (one of the operators that constitutes) is performed by a performance operator-related process (steps S24 to S26 in FIG. 4A) that is executed.

  The setting operator-related processing is executed when looper-related processing (steps S13 to S21 in FIG. 4B) executed when the repeated recording function (looper function) is set, and when other settings are made. Other setting processing (step S22 in FIG. 4B). The setting of the looper function specifically means that any item is selected by the slider 21. In addition, specific examples of other setting processes include volume adjustment, tone color setting, automatic performance setting, and effect setting. The other setting process is not a feature of the present invention and will not be described further.

  When the user sets the slider 21 (knob 21a) to “CLEAR”, the CPU 5 clears (erases) a temporary recording area (not shown) secured on the RAM 7 for recording and recording performance data. Further, both the recording flag and the reproduction flag are reset (“0”) (step S14). Thereafter, the CPU 5 ends the processing related to the setting operator (return). Thus, the setting item “CLEAR” instructs to erase the temporary recording area.

  When the user sets the slider 21 to “REC”, the CPU 5 sets a recording flag (“1”) (step S16). Thereafter, the CPU 5 ends the processing related to the setting operator (return). The recording flag is set when the start of recording is instructed, and is reset when the end of recording is instructed. The actual recording process is performed in steps S38 and S39 in FIG. 5, which will be described later. The setting item “REC” instructs execution of the recording process.

  When the user sets the slider 21 to “PLAY”, the CPU 5 sets the reproduction flag and resets the recording flag (step S18). Thereafter, the CPU 5 ends the processing related to the setting operator (return). The reproduction flag is set when an instruction to start reproduction is given, and is reset when a pause ("PAUSE") is designated. The actual reproduction process is performed in steps S32 to S34 in FIG. 5 to be described later, but the setting item “PLAY” instructs execution of the reproduction process.

  When the user sets the slider 21 to “PAUSE”, the CPU 5 resets the reproduction flag (step S20). Thereafter, the CPU 5 ends the processing related to the setting operator (return). As described above, the setting item “PAUSE” instructs to pause the reproduction process.

  When the user sets the slider 21 to “STOP”, the CPU 5 returns the pointer indicating the performance data reading position in the temporary recording area to the start position (the beginning of the temporary recording area) (step S21). Thereafter, the CPU 5 ends the processing related to the setting operator (return). As described above, the setting item “STOP” instructs to continue the pause of the reproduction process and initialize the performance data reading position. The position where the pointer is returned is not limited to the start position, but may be the end position (the end of the temporary recording area).

  The performance operator-related processing includes key-on input processing (step S25 in FIG. 4A) and other input processing (step S26).

  In the key-on (key pressing) input process, the CPU 5 outputs performance data corresponding to the key and the operation state. This performance data output is used in the sound generation / recording process of FIG.

  Other input processing “others” is mainly key-off (key release), but if the performance operator 1 includes, for example, a pedal or a wheel in addition to the keyboard, the event output by the operation Are also included in “Others”.

  FIG. 5 is a flowchart showing a detailed procedure of the sound generation / recording process in step S3. The main sound generation / recording process includes a sound generation process (step S41) that is always executed when the main sound generation / recording process is activated, a reproduction process (steps S32 to S34) that is executed when the reproduction flag is set, and performance data. The performance data is output to the sound generation process (step S40) that is always executed when there is an output, and the recording process that is executed when the performance data is output and the recording flag is set (steps S37 to S37). S39).

  In the reproduction process, first, the CPU 5 sequentially reads the performance data at the position indicated by the pointer from the temporary recording area, and passes the read performance data to the sound generation process (step S32). Next, the CPU 5 determines whether reading has been completed from the position indicated by the pointer to the last data in the temporary recording area. As a result of this determination, when the reading of the last data has not been completed, the CPU 5 ends the reproduction process. On the other hand, when the reading of the last data is completed, the CPU 5 returns the pointer reading position to the beginning, that is, the beginning of the temporary recording area (step S34), and then ends the reproduction process. As a result, as long as the reproduction flag is set, the performance data in the temporary recording area is reproduced in a loop.

  In the recording process, first, the CPU 5 determines the state of the reproduction flag, and if it is in the reset state, records the output performance data in the temporary recording area according to the elapsed time from the start of recording (step S39). When the recording flag is in the set state and the reproduction flag is in the reset state, the item selection state transitions from “CLEAR” to “REC” (see steps S14 and S16 in FIG. 4B). Therefore, in this case, performance data is recorded from the beginning in the temporary recording area in the clear state.

  On the other hand, if the reproduction flag is set, performance data is recorded in the temporary recording area in association with the reproduction position (step S38). When the recording flag is in the set state and the playback flag is in the set state, the item selection state is changed from “PLAY” to “REC” (see steps S18 and S16 in FIG. 4B). In this case, since the performance data has already been recorded in the temporary recording area (otherwise it cannot be reproduced), the output performance data is newly recorded from the reproduction position at the time of switching to “REC”. go.

  FIG. 6 shows a specific example in this case. In the figure, it is assumed that the point A is the head of the temporary recording area, and the performance data is recorded in the range from the point A to the point C by this recording process. Currently, playback processing is in progress, and when playback progresses and reaches point B, the user switches the selection state of the item from “PLAY” to “REC”. Then, new performance data is recorded from the point B in the temporary recording area. At this time, since the performance data is already recorded in the range from the point B to the point C, the new performance data is overwritten (overdubbed) on the old performance data. When this state continues and recording proceeds and reaches point C, it returns to point A and overwriting continues.

  When the selection item transitions from “CLEAR” to “REC”, the performance data is recorded in order from the beginning of the temporary recording area as described above. Then, once the transition is made from “REC” to another selection item, for example, “PLAY”, the area in which the performance data is recorded in the temporary recording area is fixed. Of course, when the transition is made from “REC” to “PAUSE” and then transits to “REC” again, the temporary recording area is cleared, so that performance data is recorded from the beginning. That is, the transition to the “other selection item” means a transition other than “PAUSE”. Therefore, the transition from “REC” to “PLAY”, “PAUSE”, “PLAY”, and “REC”, as described above with reference to FIG. New performance data is overdubbed while looping.

  In the sound generation process, the CPU 5 supplies the performance data passed in steps S32 and S40 to the sound source / effect circuit 11 as it is. This is because the sound source / effect circuit 11 converts performance data into a musical tone signal as described above with reference to FIG. As a result, the sound sound from the sound system 12 is generated by the reproduction process and / or the performance sound using the performance operator 1.

  As described above, in this embodiment, the selection items are arranged in the order of “CLEAR”, “REC”, “PLAY”, “PAUSE”, and “STOP” so that only adjacent items can be selected. Since this sequence and the transition of the selection items are an ideal procedure for effectively using the repeated recording function, even a user unfamiliar with the repeated recording function can sufficiently perform the function according to the ideal procedure. Now you can use it.

  The performance data obviously includes MIDI data, but also includes audio data, that is, a sampled analog musical sound waveform. Also, any format of performance data may be adopted.

  When the transition is made from “PLAY” to “PAUSE”, both the recording flag and the reproduction flag are in a reset state (see steps S18 and S20 in FIG. 4B), so that both the reproduction process and the recording process are stopped. Therefore, the pointer maintains the value at the time of transition from “PLAY” to “PAUSE”. For this reason, when the transition is made from “PAUSE” to “PLAY”, “PAUSE” is selected, and reading starts again from the position (next performance data) in the temporary recording area where reading is stopped.

  In the present embodiment, the present invention has been described on the assumption that “PAUSE” is included in the selection items. However, the object of the present invention can be achieved even if “PAUSE” is excluded. In this case, the selection items in the slider 21 are arranged in the order of “CLEAR”, “REC”, “PLAY”, and “STOP”. In this case, the determination in step S19 in FIG. 4B is not necessary and is deleted, and the “regeneration flag reset process” in step S20 is moved before the process in step S21. Thus, when “STOP” is selected, playback is stopped and the performance data read position is initialized.

  Further, between “CLEAR” and “REC”, “RETRY” indicating “undo” at the time of overdubbing may be inserted as a selection item. In this case, the selection items in the slider 21 are arranged in the order of “CLEAR”, “RETRY”, “REC”, “PLAY”, and “STOP”.

  Further, “REVERSE” instructing reverse playback may be inserted as a selection item after “STOP”. In this case, the selection items in the slider 21 are arranged in the order of “CLEAR”, “REC”, “PLAY”, “STOP”, and “REVERSE”.

  When switching from “CLEAR” to “REC”, a click sound (metronome sound) may be generated at a speed arbitrarily set by the user in advance. Thereby, the user can perform a performance for recording while listening to the click sound. When switching from “REC” to “PLAY”, it is assumed that no click sound is produced when the recorded one is played back. Further, when “PLAY” is switched to “REC”, the sound of “PLAY” is pronounced, so that it is not necessary to make a click sound this time.

  In “REC”, if the user has already pronounced a past performance, etc., the user can add a new performance while listening to the pronunciation, so the need for a click sound is low. In order to make it easy to understand how to take, it may be possible to set a click sound to always sound.

  A program in which a storage medium storing software program codes for realizing the functions of the above-described embodiments is supplied to a system or apparatus, and a computer (or CPU or MPU) of the system or apparatus is stored in the storage medium. 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.
