Hereinafter, embodiments of the present invention will be described with reference to the drawings.
A. Constitution
FIG. 1 is a block diagram showing a configuration of a practice device 100 according to an embodiment of the present invention. In this figure, the keyboard 10 generates performance information such as key-on / key-off events, key numbers, and velocities in response to pressing and releasing keys. The switch unit 11 has various operation switches arranged on the apparatus panel, and generates a switch event corresponding to the operated switch type. As a main switch according to the present invention, there is provided a mode switch MODE that functions as a so-called toggle switch that alternately indicates “practice start” and “practice end” each time it is turned on.

  Specifically, based on a switch event that occurs in response to the ON operation of the mode switch MODE, a CPU 12 described later executes a mode switch interrupt process (described later) to invert the mode flag MODEF. If the reversed mode flag MODEF is “1”, it indicates “practice start”, while if the reversed mode flag MODEF is “0”, it indicates “practice end”. “Practice start” refers to the execution of lesson processing described later, and “practice end” refers to the end of the lesson processing.

  The CPU 12 controls each part of the apparatus according to a switch event generated by the switch unit 11, and controls the sound source 18 according to performance information generated by the keyboard 10. The characteristic processing operation of the CPU 12 according to the gist of the present invention will be described later. The ROM 13 stores various program data loaded into the CPU 12. The various programs mentioned here include a main routine, mode switch interrupt processing, random interrupt processing, and lesson processing, which will be described later.

  The RAM 14 includes a work area and a problem sound area. In the work area of the RAM 14, various register / flag data used for the processing of the CPU 12 are temporarily stored. In the problem sound area of the RAM 14, a plurality of types of problem sounds corresponding to the step data STEP are stored. Step data STEP is data representing a stage (step level) that the user can hear as an absolute pitch. Therefore, in other words, various problem sounds having difficulty levels corresponding to the absolute sound capability (step level) of the user are stored in the problem sound area of the RAM 14.

  If the problem sound of the difficulty level corresponding to the user's absolute pitch ability (step level) is a stage at which a single piano sound can be heard as an absolute pitch as in the example shown in FIG. 2, the step data STEP is the step level. “1”. If the chord of the piano sound can be heard as an absolute pitch, the step data STEP has a step level “2”. If a single tone other than the piano sound can be heard as an absolute pitch, the step level is “3”. If a chord of a tone other than the piano sound can be heard as an absolute pitch, the step level is “4”. Further, if the piano melody can be heard as an absolute pitch, the step level is “5”. If the melody of the tone other than the piano sound can be heard as an absolute pitch, the step level is “6”. Sounds other than piano sounds include instrument sounds other than piano, as well as artificial sounds with pitch elements (such as whistles and horn sounds) and natural sounds (such as whispers and thunders). Including.

  The LED unit 15 includes LEDs (light emitting elements) arranged for each key of the keyboard 10 and a driver (not shown) that drives the LEDs to be lit, and is designated according to a control signal supplied from the CPU 12. Turn on the key LED. Under the control of the CPU 12, the LED unit 15 turns on the LED of the key corresponding to the question sound that is given (sounded), thereby notifying the correctness of the user's key pressing operation (answer operation). The external memory 16 stores the user's individual step data STEP at the end of practice.

  The display unit 17 is composed of an LCD panel or the like, and displays the operation mode of the apparatus in accordance with a display control signal supplied from the CPU 12, and displays the correctness / incorrectness of the user's answer (key press operation) corresponding to the question. The sound source 18 is configured by a well-known waveform memory readout method, and reads out waveform data corresponding to a musical tone parameter generated by the CPU 12 based on performance information to generate a musical tone waveform. The sound system 19 converts the musical sound waveform output from the sound source 18 into an analog musical tone signal, and then performs filtering such as removing unnecessary noise from the musical tone signal, and then amplifies the level and causes the speaker to generate sound.

B. Operation Next, the operation of the CPU 12 included in the practice apparatus 100 will be described with reference to FIGS. In the following, the operation of the main routine will be described first, then the mode switch interrupt processing and random interrupt processing that are executed during the execution of this main routine will be described, and lessons will be called from the mode switch interrupt processing. The processing operation will be described.

(1) Operation of Main Routine When power is turned on to the practice device 100 having the above configuration, the CPU 12 executes the main routine shown in FIG. 3 and proceeds to Step SA1, where various registers stored in the work area of the RAM 14 In addition to resetting the flag data to zero or setting an initial value, initialization is performed to instruct the sound source 18 to perform initialization. Subsequently, in step SA2, it is determined whether or not the mode flag MODEF is “0”, that is, whether or not the practice has been completed. If the practice is completed, the determination result is “YES”, and the process returns to step SA2. That is, in step SA2, the operation waits until the mode flag MODEF is set to “1” by the on operation of the mode switch MODE and the practice starts.

  In a mode switch interrupt process (see FIG. 4) to be described later, when the mode flag MODEF is set to “1” by turning on the mode switch MODE, and the state is shifted to the practice start state, the determination result in step SA2 is “NO”. Thus, the process proceeds to step SA3. In step SA3, in accordance with the user's key pressing operation (answer operation) corresponding to the question sound (pronounced), a performance process is executed to instruct the sound source 18 to generate a musical tone having the pitch of the key pressed. To do.

  Subsequently, the process proceeds to step SA4 to generate a random interrupt timing at which the generation interval (cycle) changes randomly based on a known random function. This random interrupt timing is used as an interrupt timing for executing a random interrupt process (see FIG. 5) described later. Then, when the generation of the random interrupt timing is completed, the processing is returned to the above step SA2. Thereafter, steps SA2 to SA4 are repeatedly performed while the practice start state (mode flag MODEF is “1”) is maintained.

(2) Operation of Mode Switch Interrupt Processing Next, the operation of mode switch interrupt processing will be described with reference to FIG. When a switch event corresponding to an ON operation of the mode switch MODE provided in the switch unit 11 is generated, the CPU 12 executes a mode switch interrupt process shown in FIG. 4, proceeds to step SB1, and the mode flag MODEF is “0”. Whether or not the mode switch MODE has been turned on at the end of practice.

  If the mode switch MODE is turned on with the practice finished, the determination result is “YES”, the process proceeds to step SB2, the mode flag MODEF is set to “1”, and the practice transition is started. Then, the process proceeds to step SB3, a lesson process to be described later is executed, and the process ends.

  In the lesson process, as will be described later, a “step question” using a question sound of difficulty corresponding to the current step data STEP is presented (pronounced), and a key having the same pitch as the question sound that was presented is pressed. The answer specified by the operation is advanced, and when the number of correct answers exceeds a predetermined number, the step level of the step data STEP is promoted. In the lesson process, during the course of answering these “step questions”, a “challenge question” or “confirmation question” that tests the ability of the absolute pitch at a time according to a random cycle based on the random interrupt timing described above. ”.

  In the “challenge question”, the question sounds of the difficulty level of the step level (STEP + 1) that is one step higher than the current step data STEP are sequentially given, and the number of consecutive correct answers is incremented each time the answer is correct. However, if the answer is incorrect, the number of consecutive correct answers is reset to zero. When you have answered all the questions and the number of correct answers exceeds the specified number and clear the “challenge question”, 3 points are added as the bonus points for the “step question” and the number of consecutive correct answers exceeds the specified number. Then, the step level of the current step data STEP is further promoted.

  In the “confirmation question”, the question sounds of the difficulty level of the step level (STEP-1) one step lower than the current step data STEP are sequentially given, and the number of consecutive incorrect answers is incremented each time the answer becomes incorrect. However, if even one question is answered correctly, the number of consecutive incorrect answers is reset to zero. If the number of incorrect answers exceeds the predetermined number after answering all questions, the number of correct answers for the “step question” is subtracted by 3 points as a penalty, and if the number of consecutive incorrect answers exceeds the predetermined number, The step level of the step data STEP is demoted.

  On the other hand, when the mode flag MODEF is “1”, that is, when the mode switch MODE is turned on in the practice start state, the determination result of the above step SB1 becomes “NO”, the process proceeds to step SB4, and the mode flag MODEF is entered. Is reset to zero and transition to the end of practice state. Thereafter, the process proceeds to step SB5, step data stored in the register STEP of the RAM 14 is saved and stored in the external memory 16, and the process is finished.

(3) Operation of Random Interrupt Processing Next, the operation of random interrupt processing will be described with reference to FIG. When the random interrupt timing generated in step SA4 of the main routine (see FIG. 3) is reached, the CPU 12 executes the random interrupt process shown in FIG. 5, and proceeds to step SC1. In step SC1, it is determined whether or not the mode flag MODEF is “1”, that is, whether or not the practice has been started. If the practice is stopped (the mode flag MODEF is “0”), the determination result is “NO”, and the process is terminated.

  On the other hand, if the practice has been started, the determination result in step SC1 is “YES”, and the flow proceeds to step SC2. In step SC2, it is determined whether or not the interrupt flag INTF is “0”, that is, whether or not all of the “challenge questions” (or “confirmation questions”) have been answered in the lesson processing described later. . In the lesson process described later, if the “challenge question” is being answered (interrupt flag INTF is “1”) or the “confirmation question” is being answered (interrupt flag INTF is “2”), The determination result is “NO”, and this processing is completed.

  On the other hand, in the lesson processing described later, if all of the “challenge questions” (or “confirmation questions”) have been answered, the interrupt flag INTF is set to “0”. The determination result is “YES”, and the flow proceeds to step SC3. In step SC3, a random number is generated based on a known random function, and in the subsequent step SC4, it is determined whether or not the generated random number is an even number.

  If the generated random number is an even number, the determination result is “YES”, the process proceeds to step SC5, and the interrupt flag INTF is set to “1”. When the interrupt flag INTF is set to “1”, a “challenge problem” is given in a lesson process described later. On the other hand, if the generated random number is an odd number, the determination result in step SC4 is “NO”, the process proceeds to step SC6, and the interrupt flag INTF is set to “2”. When the interrupt flag INTF is set to “2”, a “confirmation question” is given in the lesson process described later.

  As described above, the random interrupt processing is executed at each random interrupt timing at which the generation interval (cycle) changes at random, and at the execution timing, the practice start state (mode flag MODEF is “1”), In addition, in the lesson process described later, if all of the “challenge questions” (or “confirmation questions”) have been answered (the interrupt flag INTF is “0”), a random number is generated, and the generated random number is an even number. Or it is discriminated whether it is an odd number. If the generated random number is even, the interrupt flag INTF is set to “1” to instruct the start of the “challenge problem” question. On the other hand, if the generated random number is odd, the interrupt flag INTF is set to “2”. Instruct the start of the question of “confirmation question”. Therefore, since the occurrence interval (cycle) changes randomly, the “challenge problem” and “confirmation problem” that test the ability of absolute pitch at the time of hitting the user's intentions are presented, and the game is interesting. As a result, it is possible to gain new enjoyment and enhance learning effects through practice.

(4) Lesson Processing Operation Next, the lesson processing operation will be described with reference to FIGS. As described above, in steps SD1 to SD21 of the lesson process, “step questions” using question sounds of difficulty corresponding to the current step data STEP are sequentially given, and the same sounds as the question sounds that are given (pronounced) questions. Advance the answer to which the high sound is applied, and when the number of correct answers incremented every time the answer becomes correct, the step level of the step data STEP is promoted while the answer to these “step questions” is advanced. In the process, a “challenge problem” in steps SD22 to SD42 and a “confirmation problem” in steps SD43 to SD65 are given according to a random cycle. Hereinafter, such an operation will be described in detail.

  When this process is executed through the above-described step SB3 (see FIG. 4) of the mode switch interrupt process, the process proceeds to step SD1 shown in FIG. 6, and the step data STEP saved and stored at the end of the previous practice is stored in the external memory. In step SD2 read from step 16, the read step data STEP is stored in the register STEP. Hereinafter, the contents of the register STEP will be referred to as step data STEP that represents a stage (step level) in which an auditory sense can be heard.

  Next, in step SD3, the register OK for counting the number of correct answers is reset to zero. Hereinafter, the contents of the register OK are referred to as the correct number OK. In step SD4, problem sounds of difficulty corresponding to the step data STEP are created at random. Specifically, the type of problem sound corresponding to the step data STEP is randomly selected from the problem sound area of the RAM 14. For example, if the step level of the step data STEP is “2”, the step data STEP is randomly selected from a plurality of “chords (pianos)”.

  Subsequently, in step SD5, the register MISS for counting the number of incorrect answers is reset to zero. Hereinafter, the contents of the register MISS are referred to as an incorrect answer number MISS. Next, in step SD6, the sound source 18 is instructed to generate the problem sound created (selected) in step SD4. In response to this, when the sound source 18 generates a question sound and the question is given, the process proceeds to step SD7, and a key pressing wait is started. The start of the key press waiting means starting a timer that measures the time from when the question is given (problem sound generation) until the user presses the answer sound.

  In steps SD8 to SD9, it is determined whether or not there is a key press until a predetermined time elapses after the key press wait start. If the user does not press the answer sound from the start of the key press waiting until the predetermined time elapses, the determination result in step SD9 is “YES”, and the process proceeds to step SD22 (described later) shown in FIG. If the user presses the answering sound after a certain time has elapsed from the start of the key press waiting, the determination result in step SD8 becomes “YES”, and the process proceeds to step SD10.

  In step SD10, a correct / incorrect determination is made by comparing the question sound with the pressed answer sound. If the question sound and the answer sound match and are determined to be the correct answer, the process proceeds to step SD11, the correct answer number OK is incremented and stepped, and in the subsequent step SD12, “display is correct!” Is displayed. A message is displayed on the screen, and correct notification is executed to instruct the LED unit 15 to turn on the LED of the key corresponding to the problem sound.

  Thereafter, the process proceeds to step SD17 shown in FIG. 7, and it is determined whether or not the number of correct answers OK has exceeded a predetermined number of times, that is, whether or not the correct number of correct answers has been made consecutively. When the number of correct answers OK does not exceed the predetermined number of times, that is, when the correct number of correct answers has not been repeated continuously, the determination result is “NO”, and the process proceeds to step SD22 (see FIG. 8) described later.

  On the other hand, if the number of correct answers OK exceeds the predetermined number of times by correctly answering the predetermined number of times, the determination result in step SD17 is “YES”, and the process proceeds to step SD18. In step SD18, it is determined whether or not the step data STEP has not reached the highest level. If the step data STEP has already reached the highest level, the determination result is “NO”, the process proceeds to step SD20, and the completion of the lesson is displayed on the display unit 17. Thereafter, the process proceeds to step SD21, where the mode flag MODEF is reset to zero, thereby transitioning to a practice stop state and finishing this process.

  On the other hand, if the step data STEP does not reach the maximum level, the determination result in step SD18 is “YES”, and the process proceeds to step SD19, where the step data STEP is incremented and the step level is further increased. Thereafter, the process is returned to the above-described step SD3 (see FIG. 6), and the practice of answering the “step problem” that has been increased in difficulty with the step level promotion is advanced.

  On the other hand, it is assumed that the question sound does not match the keyed answer sound, and it is determined that the answer is incorrect in step SD10 (see FIG. 6). Then, the process proceeds to step SD13 shown in FIG. 6 and the correct answer number OK is reset to zero. Then, the process proceeds to step SD14, and the incorrect answer number MISS is incremented and advanced. That is, once an incorrect answer is obtained, the correct answer number OK that has been counted is reset to zero and the incorrect answer number MISS is incremented. Then, the process proceeds to step SD15, and it is determined whether or not the number of incorrect answers MISS that has been advanced exceeds a predetermined number of times, that is, whether or not one question has been determined to be an incorrect number of times. If one question has not been mistaken a predetermined number of times and the number of incorrect answers MISS does not exceed the predetermined number, the determination result is “NO”, the process returns to step SD6, and the problem sound is pronounced (re-exposed).

  On the other hand, if one question is answered incorrectly a predetermined number of times, and as a result, if the number of incorrect answers MISS exceeds the predetermined number of times, the determination result in step SD15 is “YES”, and the process proceeds to step SD16. Step 17 shown in FIG. 8 is executed after the message “Illegal answer” is displayed on the screen 17 and the LED unit 15 is informed that the LED of the key corresponding to the problem sound is lit. Proceed to SD22.

  As mentioned above, if there is no answer (key press) between the start of key press waiting and the elapse of a certain period of time, or if a correct answer cannot be made consecutively a predetermined number of times, or if one question is answered incorrectly a predetermined number of times If YES, the process proceeds to step SD22 shown in FIG. In step SD22, it is determined whether or not the interrupt flag INTF is set to “1”, that is, whether or not it is time to ask the “challenge problem”. If the interrupt flag INTF is set to “1” and it is time to give a “challenge problem”, the determination result is “YES”, and steps SD23 and after are executed.

  If it is not time to give the “challenge question”, the determination result in step SD22 is “NO”, the process proceeds to step SD43 shown in FIG. 10, and whether or not the interrupt flag INTF is set to “2”. That is, it is determined whether it is time to ask a “confirmation question”. If the interrupt flag INTF is set to “2” and it is time to give a “confirmation question”, the determination result is “YES”, and steps SD44 and after are executed. If it is not time to ask the “confirmation question”, the determination result in step SD43 is “NO”, and the process is terminated.

  As described above, in step SD22 and subsequent steps shown in FIG. 8, the “challenge problem” or “confirmation problem” is presented at a randomly changing period based on the value of the interrupt flag INTF. In the following, the operation will be described separately when a “challenge question” is given and when a “confirmation question” is given.

<When asking “challenge questions”>
If the interrupt flag INTF is set to “1” and it is time to ask “challenge problem”, the determination result in step SD22 shown in FIG. 8 is “YES”, and the process proceeds to step SD23 to indicate the current step level. It is determined whether or not the data STEP has not reached the highest level. If the step data STEP has already reached the highest level, the determination result is “NO”, the process proceeds to step SD24, the interrupt flag INTF is set to “2”, and then the process proceeds to step SD43 shown in FIG. Execute the action to ask the “confirmation problem”. In other words, if the current step level is the highest level, it is not necessary to perform the “challenge problem” corresponding to the promotion test, so the process proceeds to step SD43 shown in FIG.

  On the other hand, if the step data STEP has not reached the highest level, the determination result in step SD23 is “YES”, and the process proceeds to step SD25. For example, the message “Start challenge problem” is displayed on the display screen of the display unit 17. Is displayed to notify the user of the start of the “challenge problem”. Next, in step SD26, the registers N, YES, and RYES are each reset to zero.

  The register N counts the number of questions of the challenge problem, and the contents of the register N are hereinafter referred to as the number N of questions. The register YES counts the number of correct answers to the challenge problem, and the contents of the register YES are hereinafter referred to as challenge problem correct answer number YES. The register RYES is a register that counts the number of consecutive correct answers of the challenge problem. Hereinafter, the content of the register RYES is referred to as a challenge problem continuous correct number of answers RYES.

  When the number of questions N, challenge question correct answer YES, and challenge question continuous correct answer number RYES are each zero-reset, the CPU 12 proceeds to step SD27 to obtain “challenge problem” from step data STEP (current step level). A question sound having a difficulty level corresponding to the step level (STEP + 1), which is one level higher, is randomly selected from the problem sound area of the RAM 14, and in the subsequent step SD28, the sound source 18 is instructed to pronounce the selected problem sound.

  When the problem sound at the step level (STEP + 1), which is one step higher, is pronounced (challenge) as “challenge problem”, the process proceeds to step SD29 and waits for a key depression. Subsequently, in steps SD30 to SD31, it is determined whether or not there is a key press before a predetermined time elapses after the key press wait start. If the user presses the answer sound from the start of key press waiting until a certain time elapses, the determination result in step SD30 is “YES”, and the process proceeds to step SD32 to compare the question sound with the answer sound pressed. Then correct / incorrect judgment is made.

  If the question sound and the answer sound pressed are determined to be correct, the process proceeds to steps SD33 to SD34, and the challenge question correct answer number YES and the challenge question continuous correct answer number RYES are respectively incremented and stepped. In subsequent step SD35, the number N of questions is incremented and stepped, and then the process proceeds to step SD37 shown in FIG.

  On the other hand, if the question sound does not match the keyed answer sound and it is determined that the answer is incorrect, the process proceeds to step SD36. Even when the user does not press the answering sound after a certain time has elapsed from the start of the key press waiting, the determination result in step SD31 is “YES”, and the process proceeds to step SD36. Then, in step SD36, the challenge question continuous correct answer number RYES is reset to zero.

  After that, the process proceeds to step SD35, the number N of questions is incremented and stepped, and then the process proceeds to step SD37 shown in FIG. In step SD37, it is determined whether or not the number N of questions has exceeded a predetermined number, that is, whether or not all “challenge questions” have been given. If all questions have not been given, the determination result is “NO”, and the process returns to step SD27 (see FIG. 8) to continue the “challenge question” question.

  On the other hand, when all the “challenge questions” are given, the determination result in step SD37 is “YES”, and the process proceeds to step SD38. In step SD38, it is determined whether or not the challenge question correct answer number YES exceeds a predetermined number, that is, whether or not the “challenge problem” has been cleared. If the challenge question correct answer number YES does not exceed the predetermined number and the “challenge question” cannot be cleared, the determination result becomes “NO”, the process proceeds to step SD42, the interrupt flag INTF is reset to zero, Transition to a state in which the “challenge problem” has been completed, and this processing is completed.

  On the other hand, if the challenge question correct answer number exceeds the predetermined number and the “challenge problem” can be cleared, the determination result in the above step SD38 becomes “YES”, and the process proceeds to step SD39, where the correct answer OK is set to “3”. Add and update. That is, the correct number OK is added by 3 points as a bonus point for clearing the “challenge problem”.

  Subsequently, in step SD40, it is determined whether or not the challenge question consecutive correct answer number RYES exceeds a predetermined number, that is, whether the result is equivalent to a step level promotion. If the number of consecutive correct questions RYES does not exceed the predetermined number and the result does not correspond to the step level promotion, the determination result is “NO”, the process proceeds to step SD42, the interrupt flag INTF is reset to zero, and this process is terminated.

  On the other hand, if the challenge question consecutive correct answer number RYES exceeds a predetermined number and the result is equivalent to the step level promotion, the determination result in step SD40 is “YES”, the process proceeds to step SD41, and the step data STEP is incremented. After the step level is promoted by one step, the process proceeds to step SD42, where the interrupt flag INTF is reset to zero and the process is terminated.

  Thus, in the “challenge question” question, each time the correct answer is made, the challenge question continuous correct answer number RYES is incremented by one. However, if even one question is incorrect, the challenge problem continuous correct answer number RYES is reset to zero. . Then, when all of the “challenge questions” have been answered, if the challenge question correct answer YES exceeds the predetermined number and the “challenge questions” can be cleared, the correct answer OK is added by 3 points as a bonus point. If the challenge question consecutive correct answer number RYES exceeds the predetermined number and the result is equivalent to the step level promotion, the step level is further promoted.

<If you want to ask “confirmation questions”>
If the interrupt flag INTF is set to “2” and it is time to ask “confirmation question”, the determination result in step SD43 shown in FIG. 10 becomes “YES”, and the process proceeds to step SD44. In step SD44, it is determined whether or not step data STEP representing the current step level is above the minimum level. If the current step level is the lowest level, the determination result is “NO”, the process proceeds to step SD45, the interrupt flag INTF is set to “1”, and then the process proceeds to step SD22 shown in FIG. Execute the action when the question is asked.

  On the other hand, if the current step level is higher than the lowest level, the determination result in step SD44 is “YES”, and the process proceeds to step SD46. For example, the confirmation screen starts on the display screen of the display unit 17. A message is displayed to notify the user of the start of the “confirmation question”. Next, in step SD47, the number N of questions, the register NO, and the register RNO are each reset to zero. Note that the register NO counts the number of incorrect answers to the confirmation problem, and the contents of the register NO are hereinafter referred to as the confirmation problem incorrect answer number NO. The register RNO is a register that counts the number of consecutive incorrect answers of the confirmation problem. Hereinafter, the contents of the register RNO will be referred to as a confirmation problem continuous incorrect answer number RNO.

  When the number N of questions, the number of incorrect confirmation questions NO, and the number of consecutive incorrect verification questions RNO have been zero-reset, the CPU 12 proceeds to step SD48, where a step level (STEP) that is one step lower than the current step level as a confirmation problem. The problem sound of the difficulty level corresponding to -1) is randomly selected from the problem sound area of the RAM 14, and in step SD49, the sound source 18 is instructed to pronounce the selected problem sound.

  When the problem sound at the lower step level (STEP-1) is pronounced (question) as a “confirmation question”, the process proceeds to step SD50 and waits for a key depression. Subsequently, in steps SD51 to SD52, it is determined whether or not there is a key press until a predetermined time elapses after the key press waiting start. If the user presses the answer sound from the start of key press waiting until a certain time elapses, the determination result in step SD51 is “YES”, and the process proceeds to step SD53, where the question sound and the answer sound pressed are compared. Then correct / incorrect judgment is made. If the question sound and the answer sound match and are determined to be correct, the process proceeds to step SD54, where the number of confirmed question continuous incorrect answers RNO is reset to zero, and then the process proceeds to step SD57 shown in FIG.

  On the other hand, if the question sound and the answer sound do not coincide with each other and it is determined that the answer is incorrect, or if the user does not press the answer sound until a predetermined time has elapsed from the start of the key press waiting, step SD55 is entered. The process proceeds to step SD57 shown in FIG. 11 after the confirmation question incorrect answer number NO is incremented and stepped, and in the subsequent step SD56, the confirmation question consecutive incorrect answer number RNO is incremented and stepped.

  In step SD57, the number N of questions is incremented and stepped, and in step SD58, whether or not the number N of questions stepped over exceeds a predetermined number, that is, whether or not all “confirmation questions” have been set. Judging. If all questions have not been given, the determination result is “NO”, the process returns to step SD48 (see FIG. 10), and the “confirmation question” question is continued. On the other hand, when all the “confirmation questions” are given, the determination result in step SD58 is “YES”, and the process proceeds to step SD59.

  In step SD59, it is determined whether or not the number of confirmation question incorrect answers NO exceeds a predetermined number. If the confirmation question incorrect answer number NO is less than the predetermined number, the determination result is “NO”, and the process proceeds to step SD63 described later. If the confirmation problem incorrect answer number NO exceeds the predetermined number, the determination result is “YES”. The process proceeds to step SD60, and the correct answer OK is subtracted by 3 points as a penalty for the number of incorrect answers.

  Next, at step SD61, it is determined whether or not the value of the number of correct answers OK subtracted by 3 points is smaller than “0”. If the value of the correct answer OK subtracted by 3 points is smaller than “0”, the determination result is “YES”, the process proceeds to step SD62, the correct answer OK is reset to zero, and then the process proceeds to step SD63. On the other hand, if the value of the number of correct answers OK subtracted by 3 points is “0” or more, the determination result in step SD61 is “NO”, and the process proceeds to step SD63.

  In step SD63, it is determined whether or not the confirmation question consecutive incorrect answer number RNO exceeds a predetermined number, that is, whether the result is equivalent to a step level demotion. If the number RNO of the confirmation question consecutive incorrect answers does not exceed the predetermined number and the result does not correspond to the step level demotion, the determination result is “NO”, the process proceeds to step SD65, the interrupt flag INTF is reset to zero, and the process is terminated. .

  On the other hand, if the number RNO of consecutive confirmation question incorrect answers exceeds the predetermined number and the result is equivalent to the step level demotion, the determination result in step SD63 is “YES”, the process proceeds to step SD64, and the step data STEP is decremented. Step down one step level. Thereafter, the process proceeds to step SD65, where the interrupt flag INTF is reset to zero and the present process is terminated.

  In this way, in the “confirmation question” question, the number RNO of the confirmation problem consecutive incorrect answers is incremented by one for each incorrect answer. However, if one answer is correct, the number of confirmation problem consecutive incorrect answers RNO range is reset to zero. Is done. When all of the “confirmation questions” have been answered, if the number of confirmation question incorrect answers NO exceeds a predetermined number, the correct answer OK is subtracted by 3 points as a penalty for the number of incorrect answers. If the problem continuous incorrect answer number RNO exceeds a predetermined number and the result is equivalent to a step level demotion, the step level is demoted by one step.

  As described above, in the present embodiment, a question sound having a difficulty level corresponding to the current step data STEP is presented (pronounced), and the user answers a sound having the same pitch as the question sound that has been presented by a key press operation. When the number of correct answers exceeds a predetermined number, the “step problem” that promotes the step level of the step data STEP is repeatedly performed, and the “challenge problem” or the “confirmation problem” is given every cycle that changes randomly in the process. .

  In the “challenge problem”, the question sound of the difficulty level of the step level (STEP + 1), which is one step higher than the current step data STEP, is given, and the number of consecutive correct answers is incremented each time the answer is correct. If the answer is incorrect, the number of consecutive correct answers is reset to zero. When you have answered all the questions and the number of correct answers exceeds the specified number and clear the “challenge question”, 3 points are added as the bonus points for the “step question” and the number of consecutive correct answers exceeds the specified number. Then, the step level of the current step data STEP is further promoted.

  In the “confirmation question”, the question sounds of the difficulty level of the step level (STEP-1) one step lower than the current step data STEP are sequentially given, and the number of consecutive incorrect answers is incremented each time the answer becomes incorrect. However, if even one question is answered correctly, the number of consecutive incorrect answers is reset to zero. If the number of incorrect answers exceeds the predetermined number after answering all questions, the number of correct answers for the “step question” is subtracted by 3 points as a penalty, and if the number of consecutive incorrect answers exceeds the predetermined number, The step level of the step data STEP is demoted.

  Therefore, while working on the “step problem”, the “challenge problem” or “confirmation problem” that will test the ability of the absolute pitch every time the user's intention is struck, that is, at a randomly changing period, A game-like fun can be created, which can be used to gain new enjoyment through practice and enhance the learning effect.

  In the above-described embodiment, for each period that randomly changes, either a “challenge problem” or a “confirmation problem” is set in accordance with the even / odd number of the generated random number. A mode in which only “challenge problem” is given for each randomly changing period or a mode in which only “confirmation problem” is given for each randomly changing period may be used.
