On the other hand, when the key of the second key range 11b (key number “m”) is pressed in the learning mode, the musical tone having the pitch corresponding to the key number “m-24”, that is, 2 from the key number “m”. A tone with a pitch that is one octave lower is produced.

  In the performance learning apparatus 10 according to the present embodiment, a navigator display area 16 is provided in which LEDs corresponding to at least the keys of the first key area 11a are arranged. In the present embodiment, the navigator display area 16 is provided in the upper part of the first key area 11a. However, the present invention is not limited to this, and an LED is provided at least inside each key of the first key area 11a. May be provided. In the present embodiment, the first key area 11a provided with the navigator display area 16 is a student key area, and the second key area 11b is a teacher key area.

  Although not shown in FIG. 1, the performance learning apparatus 10 includes an input unit 12 including a timbre designation switch for designating a tone color of a musical tone to be generated and a mode switch for designating an operation mode in the performance learning apparatus 10. Although not shown in FIG. 1, the performance learning apparatus 10 is provided with a liquid crystal display device 14 and can display an image including various information such as a timbre. The performance learning apparatus 10 according to the present embodiment operates in one of the normal mode, the first learning mode, and the second learning mode by operating a mode switch.

  In the normal mode, a musical tone having a pitch corresponding to the key number of the depressed key is generated using the keyboard 11 as a single key range. In the first learning mode, a musical tone having a pitch corresponding to the key number of the pressed key is generated for the key in the first key range, while the key pressing is performed for the key in the second key range. A tone corresponding to a key having a certain relationship in the first key range is generated in response to a key depression in the second key range, and a musical tone having a pitch two octaves lower than the key number of the key is generated. Light. In the second learning mode, a musical tone having a pitch corresponding to the key number of the pressed key is generated for the key in the first key range, while the key pressing is performed for the key in the second key range. A musical tone with a pitch that is two octaves lower than the key number of the recorded key is produced.

No) With respect to the performance data, the performance of the instructor is guided by turning on and off the LED in the first key range 11a.

  FIG. 2 is a block diagram showing the configuration of the performance learning apparatus according to the present embodiment. As shown in FIG. 2, the performance learning apparatus 10 according to the present embodiment includes a CPU 21, a ROM 22, a RAM 23, a sound system 24, a keyboard 11, an input unit 12, and a display unit 13.

  The input unit 12 includes a tone color designation switch and a mode switch. The display unit 13 includes a liquid crystal display device 14 and an LED group 15. The LEDs constituting the LED group 15 are arranged in association with the keys of the first key range 11a in the navigator display area 16 located above the first key range 11a of the electronic musical instrument.

  The CPU 21 controls the performance learning apparatus 10 as a whole, detects keys pressed on the keyboard 11 and operations of switches (mode switches) constituting the input unit 12, controls the sound system 24 according to the keys and switch operations, LED Various processes such as lighting are performed.

The ROM 22 has a waveform data area that stores waveform data for generating musical sounds such as piano, guitar, bass drum, snare drum, and cymbal.

  The RAM 23 stores a program read from the ROM 22 and data generated in the course of processing. In the present embodiment, in the second learning mode, an event and time period record based on the key pressed in the second key range 11b is generated, and is configured from the event and time period record. Performance data is stored in the RAM 23.

  The sound system 24 includes a sound source unit 26, an audio circuit 27, and a speaker 28. For example, when the sound source unit 26 receives a note-on event from the CPU 21, it reads predetermined waveform data from the waveform data area of the ROM 22, generates musical tone data of a predetermined pitch, and outputs it. The audio circuit 27 D / A converts and amplifies the musical sound data. Thereby, an acoustic signal is output from the speaker 28.

  FIG. 3 is a flowchart showing an outline of the main flow of the electronic musical instrument according to the present embodiment. When the power is turned on, the main flow starts, and after the initialization process (step 301), the processes after step 302 are repeatedly executed. As shown in FIG. 3, the CPU 21 of the performance learning apparatus 10 includes clearing of data in the RAM 23, clearing of the image on the liquid crystal display device 14, and clearing of the LED group 15 when the performance learning apparatus 10 is turned on. An initialization process is executed (step 301). When the initialization process (step 301) ends, the CPU 21 detects each operation of the switches constituting the input unit 12, and executes a switch process that executes a process according to the detected operation (step 302). FIG. 4 is a flowchart illustrating an example of the switch processing according to the present embodiment.

  As shown in FIG. 4, in the switch process, the CPU 21 determines whether any switch of the input unit 12 has been operated (step 401). If it is determined No in step 401, the switch process is terminated. When it is determined Yes in step 401, the CPU 21 determines whether the operated switch is a mode switch (step 402). When it is determined No in step 402, the CPU 21 executes processing (other switch processing) according to the operated switch (for example, tone color designation switch) (step 408).

  If it is determined Yes in step 402, the CPU 21 determines whether the normal mode is designated by the mode switch (step 403). If it is determined Yes in step 403, the CPU 21 sets “0” to the mode designation flag NF in the RAM 23 (step 404). When it is determined No in step 403, the CPU 21 determines whether the first learning mode is designated by the mode switch (step 405). If it is determined Yes in step 405, “1” is set to the mode designation flag NF in the RAM 23 (step 406). If it is determined No in step 405, “2” is set to the mode designation flag NF in the RAM 23 (step 407).

  When the switch process (step 302) ends, the CPU 21 executes a keyboard process (step 303). 5 to 9 are flowcharts showing an example of keyboard processing according to the present embodiment.

  In the keyboard processing according to the present embodiment, the key state is determined in order from the key with the smallest key number (key number “0”), and necessary processing is executed. As shown in FIG. 5, the CPU 21 initializes a parameter KN for specifying the key number to “0” (step 501). The key state indicated by the parameter KN is determined (step 502). In step 502, any of the cases indicated by the parameter KN is newly “on”, newly “off”, or the key state is “no change”. Is judged.

  If it is determined in step 502 that the key is in the “on” state, the CPU 21 determines whether the mode designation flag NF is “0”, that is, whether the performance learning device 10 is operating under the “normal mode”. Is determined (step 503). If it is determined Yes in step 503, the CPU 21 generates a note-on event for the key corresponding to KN, that is, the key having the key number KN, and sends it to the sound source unit 26 (step 504). The sound source unit 26 reads the waveform data of the specified tone color based on the specified pitch according to the note-on event, and multiplies the read waveform data by the multiplication value based on the envelope. Musical sound data is generated and output to the audio circuit 27.

  Next, the CPU 21 increments the parameter KN (step 507). If the parameter KN is equal to or less than the maximum number (“N−1” in the present embodiment) (No in step 508), the process returns to step 502.

  Even when it is determined in step 502 that the key is in the “off” state, the CPU 21 determines whether the mode designation flag NF is “0”, that is, whether the performance learning device 10 is operating under the “normal mode”. Is determined (step 505). If it is determined Yes in step 505, the CPU 21 generates a note-off event for the key corresponding to KN, that is, the key having the key number KN, and sends it to the sound source unit 26 (step 506). The sound source unit 26 multiplies the read waveform data by the multiplication value based on the release envelope in accordance with the note-off event, generates musical sound data that gradually attenuates, and outputs it to the audio circuit 27.

  If it is determined in step 502 that the key state is “no change”, it will be described later. Next, when it is determined No in step 503, that is, the performance learning device 10 is operating under one of the operation modes of the “first learning mode” or the “second learning mode”. become. When it is determined No in step 503, the CPU 21 determines whether or not the mode designation flag NF is “1” (step 601). If it is determined Yes in step 601, the CPU 21 determines whether the parameter KN is larger than the split point SP (step 604). If it is determined No in step 604, the CPU 21 generates a note-on event for the key corresponding to KN, that is, the key having the key number KN, and sends it to the sound source unit 26 (step 603). The sound source unit 26 reads the waveform data of the specified tone color based on the specified pitch according to the note-on event, and multiplies the read waveform data by the multiplication value based on the envelope. Musical sound data is generated and output to the audio circuit 27.

  Determination of Yes in step 604 means that the key in the second key area 11b has been pressed in the first learning mode. If YES is determined in step 604, the CPU 21 sets the LED lighting flag TF to “1” (step 605), and sets “KN-24” as the key number TKN based on the performance of the lecturer. (Step 606). The LED lighting flag TF and the key number TKN are stored in the RAM 23. In the present embodiment, the key number TKN indicates a pitch that is two octaves lower than the key number KN.

  Next, the CPU 21 generates a note-on event for the key corresponding to TKN, that is, the key having the key number TKN (= KN-12), and sends it to the sound source unit 26 (step 607). The sound source unit 26 reads the waveform data of the specified tone color based on the specified pitch according to the note-on event, and multiplies the read waveform data by the multiplication value based on the envelope. Musical sound data is generated and output to the audio circuit 27.

  On the other hand, if it is determined No in step 601, that is, if the mode designation flag NF is “2”, the CPU 21 determines whether the parameter KN is larger than the split point SP (step 602). If it is determined No in step 602, the CPU 21 generates a note-on event for the key corresponding to KN, that is, the key having the key number KN, and sends it to the sound source unit 26 (step 603). The sound source unit 26 reads the waveform data of the specified tone color based on the specified pitch according to the note-on event, and multiplies the read waveform data by the multiplication value based on the envelope. Musical sound data is generated and output to the audio circuit 27.

  On the other hand, if it is determined Yes in step 602, the CPU 21 refers to the RAM 23 and determines whether the recording stop flag STF stored in the RAM 23 is “1” (step 701). The recording stop flag STF controls the cancellation of the timer interrupt in the navigation process and the stop of the recording / recording operation of the performance data in the second learning mode.

  If YES is determined in step 701, the CPU 21 resets the recording stop flag STF to “0” (step 702) and sets the first timer value T to “0” (step 703). . Thereafter, the CPU 21 releases the first timer interrupt (step 704). In this specification, the cancellation of the interrupt means that the interrupt operation restriction is stopped and the interrupt operation is enabled, that is, the interrupt process can be executed.

  On the other hand, if it is determined No in step 702, that is, if the recording stop flag STF is “0”, the CPU 21 stores the timer value T of the first timer in the RAM 23 as a record of performance data. (Step 705). Thereafter, the CPU 21 resets the first timer to set the timer value T to “0” (step 706).

  After step 704 or step 706 is completed, the CPU 21 sets “KN-24” as the key number TKN based on the performance of the instructor (step 707), and the key corresponding to TKN, that is, the key number TKN (= KN-12) key-on event is generated and stored in the RAM 23 as a record of performance data (step 708). Thereafter, in step 607, the generated note-on event is sent to the sound source unit 26.

  The performance data according to this embodiment will be described below. In step 705, the timer value T is stored in the RAM 23 as a record of performance data, and in step 708, a note-on event is stored as a record of performance data. Further, as described later, in step 809, the timer value T is stored as a record of performance data in the RAM 23, and in step 809, a note-off event is stored as a record of performance data.

  FIG. 10 is a diagram illustrating a data configuration example of the generated performance data. As shown in FIG. 10, in the performance data 1000, for example, records are stored in the order of a note-on event, a time period, a note-off event, and a time period (see, for example, reference numeral 1001). Note-on event # 00 (see reference numeral 1011) includes the key number of the pressed key. The subsequent time period # 00 (see reference numeral 1012) stores a note-on event # 00 and a timer value until the next event (note-off event # 0).

  Next, when it is determined No in step 505, that is, the key of the key number KN is in the “off” state, and the performance learning device 10 is in the “first learning mode” or “second learning mode”. In any case, the CPU 21 determines whether or not the mode designation flag NF is “1” (step 801). If it is determined Yes in step 801, the CPU 21 determines whether the parameter KN is larger than the split point SP (step 802).

  If it is determined Yes in step 802, the CPU 21 determines whether “TKN + 24 = KN” (step 803). In step 803, it is determined whether or not the parameter KN corresponding to the key number of the key that is newly in the “off state” corresponds to the pitch two octaves higher than the key number TKN based on the performance of the instructor. If it is determined Yes in step 803, the LED lighting flag TF is reset to “0” (step 804). Next, the CPU 21 generates a key note-off event corresponding to TKN and sends it to the sound source unit 26 (step 805). The sound source unit 26 multiplies the read waveform data by the multiplication value based on the release envelope in accordance with the note-off event, generates musical sound data that gradually attenuates, and outputs it to the audio circuit 27. Thereafter, the process proceeds to step 507. Also, if it is determined No in step 803, the process proceeds to step 507.

  If it is determined No in step 802, that is, if the parameter KN is equal to or less than the split point SP, the CPU 21 generates a note-off event for the key corresponding to KN and sends it to the sound source unit 26 ( Step 806). The sound source unit 26 multiplies the read waveform data by the multiplication value based on the release envelope in accordance with the note-off event, generates musical sound data that gradually attenuates, and outputs it to the audio circuit 27. Thereafter, the process proceeds to step 507.

  Next, the case where No is determined in step 801 will be described. The determination of No in step 801 means that the mode designation flag NF is “2”, that is, the performance learning device 10 is operating under the second learning mode. In this case, the CPU 21 determines whether the parameter KN is larger than the split point SP (step 807). When it is determined No in step 807, the CPU 21 generates a key note-off event corresponding to KN and sends it to the sound source unit 26 (step 806).

  If it is determined Yes in step 807, the CPU 21 determines whether “TKN + 24 = KN” (step 808). If it is determined No in step 808, the process proceeds to step 507. If YES is determined in step 808, the timer value T of the first timer is stored in the RAM 23 as a record of performance data (step 809). Thereafter, the CPU 21 resets the first timer to set the timer value T to “0” (step 810). Thereafter, the CPU 21 generates a note-off event for the key corresponding to TKN and stores it in the RAM 23 as a record of performance data (step 811). The note-off event generated in step 811 is sent to the sound source unit 26 in step 805.

  Next, a case where it is determined in step 802 that “no change” will be described. In this case, the CPU 21 determines whether the recording stop flag STF is “0” (step 901). If it is determined Yes in step 901, the CPU 21 determines whether the time information (timer value T) stored in the RAM 23 exceeds a predetermined value (step 902). If NO in step 901 or NO in step 902, the process proceeds to step 507.

  If it is determined Yes in step 902, the CPU 21 reads the note-on event of the record at the head of the records that have not been read in the performance data, and corresponds to the pitch indicated by the note-on event. The LED to be turned on is turned on (step 904). Next, the CPU 21 reads the time period in the subsequent record in the performance data (step 905), and sets the time period included in the record as the second timer value t (step 906). Thereafter, the CPU 21 releases the second timer interrupt (step 907). Further, the CPU 21 sets the guide flag GF to “1” (step 908). This guide flag GF is also stored in the RAM 23.

  After the keyboard process (step 303), the CPU 21 executes a navigation process (step 304). 11 and 12 are flowcharts showing an example of the navigation processing according to the present embodiment. As shown in FIG. 11, the CPU 21 determines whether or not the mode designation flag NF is “1” (step 1101).

  When it is determined Yes in step 1101, it is determined whether the LED lighting flag TF is “1”. If it is determined Yes in step 1102, the CPU 21 refers to the TKN stored in the RAM 23 and turns on the LED corresponding to the pitch indicated by the TKN (step 1103). On the other hand, if the LED lighting flag TF is “0”, the LED corresponding to the pitch indicated by TKN is turned off (step 1104).

  If it is determined No in step 1101, it is determined whether the mode designation flag NF is “2” (step 1105). If it is determined Yes in step 1105, the CPU 21 determines whether the guide flag GF is “1” (step 1106). When it is determined Yes in step 1106, the CPU 21 determines whether or not the second timer value t is “0” or less (step 1107). If it is determined No in any of steps 1105 to 1107, the process is terminated.

  If YES is determined in step 1107, the first record among the records that have not been read out from the performance data, that is, the next record after the record read in the previous process is read (step 1202). . If there is a record to be read (No in step 1202), the CPU 21 determines the type of record (step 1203).

  If the record type is a time period, the value included in the read record is set as the second timer value t (step 1204), and the process ends.

  On the other hand, if the record type is an event, the CPU 21 determines the event type (step 1205). If the event is a note-on event, the CPU 21 turns on the LED corresponding to the pitch indicated by the note-on event (step 1206). On the other hand, if the event is a note-off event, the CPU 21 turns off the LED corresponding to the pitch indicated by the note-off event (step 1207). After steps 1206 and 1207, the process returns to step 1201.

  If it is determined No in step 1202, that is, if the performance data record has been read to the end, the CPU 21 stops the first interrupt and the second interrupt (step 1208). Further, the CPU 21 sets the recording stop flag STF to “1” (step 1209) and resets the guide flag GF to “0” (step 1210).

  When the navigation process (step 304) ends, the CPU 21 executes other processes, for example, generation and display of an image on the liquid crystal display device 14 (step 305).

  When the first timer interrupt and the second timer interrupt are released, the first timer interrupt process and the second timer interrupt process are respectively performed as shown in FIGS. 13 (a) and 13 (b). Executed. The first interrupt process and the second interrupt process are executed every predetermined unit time. As shown in FIG. 13A, in the first timer interrupt process, the first timer value T is incremented (step 1301). On the other hand, as shown in FIG. 13B, in the second timer interrupt process, the second timer value is decremented (step 1302).
