  Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a diagram showing an outline of a performance learning apparatus according to an embodiment of the present invention. As shown in FIG. 1, a performance training apparatus 10 according to the present embodiment takes the form of an electronic keyboard instrument and has a keyboard 11.

Key area 11b. For example, in the present embodiment, the first key range 11a has a 2-octave range. The key number “SP” indicates the split point. As will be described later, in the present embodiment, a musical tone having a pitch corresponding to the key number “n” is generated by pressing a key in the first key range 11a in a learning mode described later. 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 and the 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 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 pressed for the key in the second key range. A musical tone having a pitch two octaves lower than the key number of the first key range is generated, and an LED corresponding to a key having a certain relationship in the first key range is lit in response to a key depression in the second key range.

  In the learning mode, when there is a difference in pitch or time between the key depression in the first key range 11a and the key depression in the second key range 11b, no operation is performed. The recorded performance is counted when the parameter MISS exceeds a predetermined value when a predetermined time elapses after there is no new key press or key release in both key ranges. With respect to the data, the performance of the instructor's key pressing operation 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 performance learning apparatus.

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 performance learning apparatus 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, when the performance learning device 10 is turned on, the CPU 21 executes initialization processing including clearing data in the RAM 23, clearing the image on the liquid crystal display device 14, and clearing the LED group 15. (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 403).

  When it is determined Yes in step 402, the CPU 21 determines whether the learning mode is designated by the mode switch (step 404). If it is determined No in step 404, the CPU 21 sets “0” to the mode designation flag NF in the RAM 23 (step 405). Next, the CPU 21 stops the first timer interrupt (step 406).

  When it is determined Yes in step 402, the CPU 21 sets “1” to the mode designation flag NF in the RAM 23 (step 407). Thereafter, the CPU 21 stores the initial value “0” in the first timer value T (step 408), and initializes various flags and registers in the RAM 23 (step 409). Further, the CPU 21 cancels the first timer interrupt. In this specification, the release of the timer interrupt means that the operation of the timer interrupt is stopped and enabled, that is, the timer interrupt process can be executed.

  When the switch process (step 302) ends, the CPU 21 executes a keyboard process (step 303). 5 to 10 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 first determines whether or not the mode designation flag NF is “0” (step 501). If YES in step 501, that is, if the performance learning device 10 is operating in the normal mode, the CPU 21 initializes a parameter KN for specifying the key number to “0” (step 502), and the parameter KN is The state of the indicated key is determined (step 503). 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 503 that the key is in the “on” state, 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 503). 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 506). If the parameter KN is equal to or less than the maximum number (“N−1” in the present embodiment) (No in step 507), the process returns to step 503.

  If it is determined in step 503 that the key is in the “off” state, 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 503). 505). 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 506. If it is determined in step 503 that the key state is “no change”, the process also proceeds to step 506.

  Next, the case where it is determined No in step 501, that is, the case where the performance learning apparatus 10 is operating under the “learning mode” will be described. Even when it is determined No in step 501, the CPU 21 initializes the parameter KN for specifying the key number to “0” (step 601). The key status indicated by the parameter KN is determined (step 602). If it is determined in step 602 that the key is in the “on” state, the CPU 21 determines whether the parameter KN is greater than the split point SP (step 603).

  If it is determined No in step 603, the CPU 21 sets the key number KN in the parameter DKN indicating the lower key number in the RAM 23 (step 604) and sets the lower key pressing flag DF to “1”. (Step 605). Thereafter, the CPU 21 generates a note-on event of the key corresponding to KN, that is, the key having the key number KN, and sends it to the sound source unit 26 (step 606). 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.

  The determination of Yes in step 603 means that the key in the second key area 11b has been pressed in the learning mode. If YES is determined in step 603, the CPU 21 sets “KN-24” as the key number TKN based on the performance of the lecturer (step 607). In the present embodiment, the key number TKN indicates a pitch that is two octaves lower than the key number KN. Further, the CPU 21 sets the key number TKN based on the performance of the lecturer as the parameter UKN indicating the upper key number (step 608), and sets the LED lighting flag TF to “1” (step 609). Further, the CPU 21 sets the upper key depression flag UF to “1” (step 610). The key number TKN, parameter UKN, flag TF, and flag UF are stored in the RAM 23, respectively.

  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-24), and sends it to the sound source unit 26 (step 611). 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.

  After step 606 or step 611 is completed, the CPU 21 increments the parameter KN (step 612), and if the parameter KN is less than or equal to the maximum number (“N−1” in the present embodiment) (in step 613). No), it returns to step 602.

  If it is determined Yes in step 613, the CPU 21 determines whether the lower key pressing flag DF = 1 and the upper key pressing flag UF = 1 (step 701). If the result of step 701 is Yes, both the keys in the first key range 11a and the keys in the second key range 11b are obtained as a result of checking the state of each key number “0” to “N−1”. It is shown that the key of is turned on. When it is determined No in step 701, the CPU 21 determines whether the lower key pressing flag DF = 0 and the upper key pressing flag UF = 1 (step 702).

  If it is determined Yes in step 701, the CPU 21 determines whether the lower key number DKN and the upper key number UKN match (step 703). If YES is determined in step 703, the CPU 21 clears the performance data in the RAM 23 (step 704) and indicates the number of non-operations, that is, the number of performance errors when there is no key depression by the student. The parameter MISS is cleared to “0” (step 705). Further, the CPU 21 resets both the lower key pressing flag DF and the upper key pressing flag UF to “0” (step 706), and clears the lower key number DKN and the upper key number UKN (step 707). . Further, the CPU 21 resets the first timer value T to “0” (step 708).

  Next, the case where it is determined in step 602 that the key is in the “off” state will be described. In this case, the CPU 21 determines whether the parameter KN is larger than the split point SP (step 801). When it is determined Yes in step 801, the CPU 21 determines whether or not “TKN + 24 = KN” (step 802). In step 802, 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 lecturer. If it is determined Yes in step 802, the LED lighting flag TF is reset to “0” (step 803). Next, the CPU 21 generates a key note-off event corresponding to TKN and sends it to the sound source unit 26 (step 804). 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.

  Next, the CPU 21 determines whether or not the flag HF indicating that the performance is a teacher is “1” (step 805). If it is determined Yes in step 805, if it is determined Yes in step 805, the CPU 21 stores the timer value T of the first timer in the RAM 23 as a record of performance data (step 806). . Further, 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 807). Thereafter, the CPU 21 resets the first timer to set the timer value T to “0” (step 808) and resets the flag HF to “0” (step 809).

  The performance data according to the present invention will be described below. FIG. 11 is a diagram illustrating a data configuration example of the generated performance data. As shown in FIG. 11, in the performance data 1100, for example, records are stored in the order of note-on event, time period, note-off event, and time period (for example, reference numeral 1101). Note-on event # 00 (see reference numeral 1111) includes the key number of the key that has been pressed. The subsequent time period # 00 (refer to reference numeral 1112) stores a note-on event # 00 and a timer value until the next event (note-off event # 0).

  If it is determined No in step 801, the CPU 21 generates a note-off event for the key corresponding to KN and sends it to the sound source unit 26 (step 810). When step 809 or step 810 ends, the process proceeds to step 612.

  Next, the case where No is determined in step 702 will be described. When it is determined No in step 702, the CPU 21 determines whether the lower key pressing flag DF = 0 and the upper key pressing flag UF = 0 (step 901). In step 901, it is determined that a new key has not been pressed in either the first key range 11a or the second key range 11b. If it is determined Yes in step 901, the CPU 21 determines whether the first timer value T is greater than a predetermined time (step 902). When it is determined Yes in step 902, the CPU 21 further determines whether or not the parameter MISS indicating the number of non-operations is larger than a predetermined value (step 903). If it is determined No in any of steps 901 to 903, the keyboard process is terminated.

  When it is determined Yes in step 903, the CPU 21 sets the guide flag GF to “1” (step 904). The guide flag GF is also stored in the RAM 23. Next, the CPU 21 determines whether or not a record of performance data exists in the RAM 23 (step 905). When it is determined No in step 905, the CPU 21 resets the guide flag GF to “0” (step 906) and ends the keyboard process.

  When it is determined Yes in step 905, the CPU 21 reads the record located at the head among the records that have not been read in the performance data (step 907), and determines the type of the record (step 908). . If the record type is a time period, the CPU 21 sets the value included in the read record as the second timer value t (step 909). Next, the CPU 21 releases the second timer interrupt (step 910) and ends the keyboard process.

  If the record type is an event, the CPU 21 determines the event type (step 911). 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 912). 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 913). Thereafter, the CPU 21 reads the next record of the performance data (step 914) and returns to step 908.

  Next, a case where Yes is determined in Step 702 or a case where No is determined in Step 703 will be described. A determination of Yes in step 702 indicates that there is no new key press in the first key range 11a even though there is a new key press in the second key range 11b. Alternatively, the determination of No in step 703 means that there is a new key press in the second key range 11b and there is a new key press in the first key range 11a. Indicates that the key numbers (DKN, UKN) did not match.

  In this case, the CPU 21 increments the parameter MISS indicating the number of non-operations (step 1001), and the CPU 21 stores the timer value T of the first timer in the RAM 23 as a record of performance data (step 1002). ). Further, the CPU 21 generates a note-on event of a key corresponding to TKN and stores it in the RAM 23 as a record of performance data (step 1003). The CPU 21 resets the first timer value T to “0” (step 1004). Further, the CPU 21 resets both the lower key pressing flag DF and the upper key pressing flag UF to “0” (step 1005), and clears the lower key number DKN and the upper key number UKN (step 1006). Thereafter, the CPU 21 sets a flag HF indicating that the performance is performed by the teacher to “1” (step 1007), and ends the keyboard process.

  After the keyboard process (step 303), the CPU 21 executes a navigation process (step 304). 12 and 13 are flowcharts illustrating an example of the navigation process according to the present embodiment. As shown in FIG. 12, the CPU 21 determines whether or not the mode designation flag NF is “1” (step 1201). If it is determined Yes in step 1201, the CPU 21 determines whether the guide flag GF is “0” (step 1202). When it is determined Yes in step 1202, it is determined whether the LED lighting flag TF is “1” (step 1203). If it is determined Yes in step 1203, 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 1204). 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 1205).

  When it is determined No in step 1202, the CPU 21 determines whether the second timer value t is “0” or less (step 1206). When it is determined No in step 1201 or step 1206, or when step 1205 or 1204 is finished, the navigation processing process is finished.

  If it is determined Yes in step 1206, the CPU 21 reads from the performance data the first record out of the records that have not been read, that is, the record next to the record read in the previous process ( Step 1301). If there is a record to be read (No in step 1302), the CPU 21 determines the type of the record (step 1303). If the record type is a time period, the value included in the read record is set as the second timer value t (step 1304), and the navigation process is terminated.

  On the other hand, if the record type is an event, the CPU 21 determines the event type (step 1305). If the event is a note-on event, the CPU 21 lights an LED corresponding to the pitch indicated by the note-on event (step 1306). 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 1307). After steps 1306 and 1307, the process returns to step 1301.

  If it is determined No in step 1302, that is, if the performance data record is read to the end, the CPU 21 resets the guide flag GF to “0” (step 1308) and sets the number of non-operations. The indicated parameter MISS is cleared to “0” (step 1309). Further, the CPU 21 stops the second interrupt (step 1310) and clears the performance data area in the RAM 23 (step 1311).

  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 canceled, the first timer interrupt process and the second timer interrupt process are respectively performed as shown in FIGS. 14 (a) and 14 (b). Executed. The first interrupt process and the second interrupt process are executed every predetermined unit time. As shown in FIG. 14A, in the first timer interrupt process, the first timer value T is incremented (step 1401). On the other hand, as shown in FIG. 14B, in the second timer interrupt process, the second timer value is decremented (step 1402).

  Next, FIGS. 15 (a) to 15 (e) and FIGS. 16 (a) to 16 (g), which more specifically describe the turning on and off of the LEDs in the learning mode, are the key depression and key release in the learning mode. It is a figure explaining lighting and light extinction of LED after that. In FIG. 15A, the student presses the key number KNS1 in the first key range 11a, and the teacher presses the key number KNT1 key in the second key range 11b. Indicates. Here, if DKN ≠ UKN, that is, if the key numbers of the pitches to be pronounced do not match, it is determined No in step 703, and in step 1001, the parameter MISS indicating the number of non-operations is incremented. In 1002 to 1003, performance data records (time period and note-on event: see reference numeral 1502) are generated.

  After that, as shown in FIG. 15B, when the key of the instructor side key number KNT1 is released, performance data records (time period and note-off event: see reference numeral 1502) are recorded in steps 806 to 807. Generated.

  FIG. 15C shows that the instructor has pressed the key number KNT2 in the second key area 11b, but the student has not pressed the key in the first key area 11a. . In this case, it is determined No in step 701, Yes in step 702, the parameter MISS is incremented in step 1001, and performance data records (time period and note-on event: reference numeral 1503) in steps 1002 to 1003. Reference) is generated. Thereafter, as shown in FIG. 15D, when the key of the instructor side key number KNT2 is released, performance data records (time period and note-off event: see reference numeral 1504) are recorded in steps 806 to 807. Generated.

  Regarding the key pressed in the first key range 11a and the key pressed in the second key range 11b, the key number of the pitch to be pronounced does not match, or the key pressed By repeating the different timings, the parameter MISS is incremented and a record of performance data is generated. As a result, reference numeral 1505 in FIG. 15E shows an example of performance data records (note-on event, note-off event, and time period) based on key depression of note numbers KNT1 to KNTn.

  In a state where the performance data record 1600 shown in FIG. 16A is stored in the RAM 23, both the first key range 11a and the second key range 11b are stored. , It is assumed that no key has been pressed or released for a time longer than a predetermined value. As shown in FIG. 16B, when the first timer value T is larger than the predetermined time and the parameter MISS is larger than the predetermined value, “Yes” is determined in steps 902 and 903, and in step 907, The record of the note-on event KOnTKNT1 is read, and in step 912, the LED of the pitch indicated by the key number TKNT1 is turned on. In steps 909 and 910, the time period T2 in the performance record is set as the second timer value t, and the second timer interrupt is canceled.

  As shown in FIG. 16C, when the second timer interrupt t is released and the second timer value t becomes “0” or less, the performance is performed through steps 1206, 1301, 1302, and 1303. The next record of data (note-off event KOffTKNT1) is read, and in step 1307, the LED of the pitch indicated by the key number TKNT1 is turned off. In step 1304, the time period T3 in the performance data is set as the second timer value t.

  As shown in FIG. 16D, when the timer value t becomes “0” or less again, the next record (note-on event KOnTKNT2) of the performance data is read through steps 1206, 1301, 1302, and 1303. In step 1306, the LED of the pitch indicated by the key number TKNT2 is turned on. In step 1304, the time period T4 in the performance data is set as the second timer value t.

  As shown in FIG. 16E, when the second timer value t becomes “0” or less, the next record (note-off event KOffTKNT2) of the performance data is passed through steps 1206, 1301, 1302, and 1303. In step 1307, the LED having the pitch indicated by the key number TKNT2 is turned off. In step 1304, the time period T5 in the performance data is set as the second timer value t.

  The LED is repeatedly turned on and off at the time interval indicated by the timer value t. As shown in FIG. 16F, when the timer value t becomes “0” or less again, steps 1206, 1301, 1302, Through 1303 and the like, the next record of performance data (note-on event KOnTKNTn) is read, and in step 1306, the LED of the pitch indicated by the key number TKNTn is turned on. In step 1304, the time period T2n in the performance data is set as the second timer value t.

  Further, as shown in FIG. 16 (g), when the second timer value t becomes “0” or less, the next record (note-off event KOffTKNTn) of the performance data is passed through steps 1206, 1301, 1302, 1303, and the like. ) Is read, and in step 1307, the LED of the pitch indicated by the key number TKNT2 is turned off. Further, since it is the end of the record, it is determined Yes in step 1302 to be executed thereafter. Accordingly, in steps 1308 to 1311, the flag GF is reset to “0”, the parameter MISS is cleared, the second timer interrupt is stopped, and the performance data in the RAM 23 is cleared.

  In the present embodiment, when any of the keys belonging to the second key range 11b is operated, the CPU 21 has a certain correspondence in pitch with the keys belonging to the second key range 11b. The sound source unit 26 is instructed to generate musical music data having a pitch corresponding to the key belonging to the first key range 11a, and the LED corresponding to the key belonging to the first key range is turned on. In addition, when a key belonging to the second key range 11b is pressed, the CPU 21 determines whether a key belonging to the first key range 11a having a certain correspondence relationship is pressed, and the key is pressed. If not, a record of performance data based on the operation of keys belonging to the second key range is stored in the RAM 23. Further, the number of non-operations indicating the number of times a key belonging to the first key range 11a having a certain correspondence is not depressed is counted. When the counted number of non-operations becomes larger than a predetermined number, the CPU 21 lights up the LED corresponding to the key belonging to the first key range based on the record of the performance data stored in the RAM 23.

  According to the present embodiment, when the number of non-operations indicating a mismatch between the key press of the instructor in the second key range and the key press of the student in the first key range becomes greater than a predetermined number, the instructor According to a series of performances with keys operated in the key range, the LEDs associated with the keys in the first key range are sequentially lit. Therefore, the student can practice the phrase based on the operation of the series of keys by referring to the lighting of the LEDs associated with each of the series of keys in the first key range. In particular, since the LED is lit when the student cannot perform the same performance as the performance of the instructor, the student can confirm the phrase that he / she missed by lighting the LED. In that case, the lecturer can give advice by paying attention to the operation of keys equivalent to the series of keys by the student based on the lighting of the LED.

  In addition, the CPU 21 determines that the key belonging to the first key range that is pressed in response to the key pressing of the key belonging to the second key range does not correspond to the key belonging to the second key range. Alternatively, when the key belonging to the first key range is not pressed in response to the key pressing of the key belonging to the second key range, a record of performance data based on the key pressing operation of the second key range Is stored in the RAM 23. That is, when the key is pressed in the first key range but does not have a certain correspondence with the key pressed in the second key range (when the key numbers do not match), or in the first place When the key belonging to the key is not pressed, it is determined that the student has lost the phrase to be played, and performance data based on the performance of the instructor (key operation in the second key range) is generated.

  In the present embodiment, the CPU 21 determines that the number of non-operations is greater than a predetermined number when a predetermined time has elapsed after the keys in the first key range and the keys in the second key range are not operated. In accordance with the determination, the LED corresponding to the key belonging to the first key range is turned on based on the performance data stored in the RAM 23. Therefore, when the performance of both the instructor and the student is interrupted and a predetermined time elapses, it corresponds to each of the series of keys in the first key range having a certain correspondence with each of the series of keys operated by the instructor. LEDs are lit in sequence. Therefore, when the student's performance is interrupted, the instructor can also start his / her performance by suspending his / her performance, thereby starting the LED lighting guide after a predetermined time.

  Further, in the present embodiment, when the performance data is stored in the RAM 23, the CPU 21 determines that the depressed key belonging to the second key range and the depressed key belonging to the first key range. When the relationship is fixed, the performance data is cleared and the counted number of non-operations is also initialized. This means that the student has found the phrase that the instructor is playing again at that time, so the performance is continued.

  In the present embodiment, the performance data includes a note-on event indicating that the key is turned on, a note-off event indicating that the key is turned off, and a record of a time period indicating the time interval between the events. The CPU 21 reads the first note-on event that has not yet been read from the performance data record, lights up the LED corresponding to the key belonging to the first key range indicated by the note-on event, and also displays the time period. After the elapse of time, the next record is read, and when the note-off event relating to the key corresponding to the LED that is lit is read, the LED that is lit is extinguished. Therefore, the blinking of the LED can be matched with the timing of key pressing and key release by the instructor.

  In the present embodiment, an LED is used as an operator designating means for designating each key that is a performance operator. The LED may be arranged adjacent to each of the keys, or may be arranged inside each of the keys. By turning on the LED, the student can immediately know the key to be pressed.
