  In the performance guide processing system according to the first aspect of the present invention, the electronic music apparatus (EM) performs a performance for guiding a keyboard (15K) composed of a plurality of keys and what to perform for each key of the keyboard. Guide means (16L, 16E, 16D,...), And the keyboard (15K) is effectively divided into two key ranges (Rt, Rs) on the teacher side and the student side in response to a key range division instruction (M4 to M6). ). When the teacher performs an exemplary performance in the teacher's side key range (Rt) of the keyboard (15K), pitch information generated in accordance with the exemplary performance operation is sequentially input (C, D; F1 to F4). Based on each pitch information of the performance, the performance guide means (16L,...) Is controlled to start the performance guide. That is, guidance of each key is started by the performance guide means (16L,...), And a key corresponding to each pitch information (referred to as “corresponding key”) is designated in the student-side key range (Rs) to operate the student. The power is notified (E, G, H; F5 → F9). On the other hand, when the student operates the corresponding key in the student side key range (Rs) of the keyboard (15K), the pitch information generated in response to the key operation corresponds to the pitch information of the model performance. Then, the performance guide means (16L,...) Is controlled to end the guide for the corresponding key (C, D, F, G, H; F6 to F9).

  For example, when an LED guide lamp (16L) is provided for each key near the keyboard (15K) as a guide means, the student side key range ( The guide lamp (16L) indicating the corresponding key is turned on at Rs) and continues to turn on until the student plays this key. Therefore, when the student plays the corresponding key indicated by the lit guide lamp (16L), this guide lamp (16L) is turned off by using this as a trigger. If the key operation is mistaken, even if the teacher releases the key, the guide lamp (16K) remains on without being turned off, so that the student can visually recognize the wrong place. In addition, once the teacher has played, the teacher can concentrate on the lesson of the student, eliminating the conventional inconvenience. That is, according to the present invention, in an electronic music apparatus such as a keyboard instrument with a performance guide function, the keyboard performance lesson efficiency is maintained by maintaining the guide of each key to be operated based on the model performance until the corresponding key is operated. Can be raised.

  In the performance guide processing system according to the second aspect of the present invention, the electronic music apparatus (EM) performs a performance for guiding a keyboard (15K) composed of a plurality of keys and what to perform for each key of the keyboard. Guide means (16L, 16E, 16D,...) Are provided, and when the teacher performs an exemplary performance on the external electronic music device [MT (MD)], the pitch information is sequentially input (E; L1 → L2). The performance guide means (16L,...) Is controlled based on each pitch information, and starts a guide for instructing a key corresponding to the pitch information as a corresponding key to be operated (E, G, H; L2 → L6). On the other hand, when the student operates the key of the keyboard (15K) and the pitch information generated in response to the key operation corresponds to the pitch information of the model performance, the performance guide means (16L,... ) Is controlled to end the guide for the corresponding key (C, D, F, G, H; F6 to F9).

  For example, if an LED guide lamp (16K) is provided for each key in the vicinity of the keyboard (15K) as a guide means, the student side can know which key the teacher played with the teacher's electronic music device (MT). In the electronic music device (MS), a guide lamp (16K) for instructing a corresponding key is lit and continues to be lit until the student plays this key. Therefore, as described above, when the student plays the corresponding key indicated by the lighting of the guide lamp (16L), the guide lamp (16L) is turned off, but if the key operation is mistaken, the teacher releases the key. The guide lamp (16L) keeps the lighting state and informs the student of the wrong place. In addition, the teacher performs the model performance on the teacher's electronic music device (MS), which is different from the student's electronic music device (MS), so the lesson environment is difficult to grasp the student's movements. For example, you can concentrate on the lessons of the students later, eliminating the traditional disadvantages. In other words, according to the present invention, when performing a performance lesson by connecting an external electronic music device with a signal line to an electronic music device such as a keyboard instrument with a performance guide function, each key based on an exemplary performance in the external electronic music device By keeping this guide until the corresponding key is operated, the lesson efficiency of keyboard performance can be improved.

[Appearance of performance operation and guide section]
In the performance guide processing system according to one embodiment of the present invention, as described above, an electronic musical instrument EM with a performance guide function in which a performance guide section (also referred to as a performance instruction section) 6-16 is added to a normal electronic musical instrument is an electronic music. Used as a device. As will be described later, in the continuous mode (four-hand performance), the keyboard 15K is divided into the teacher side key range (Rt) and the student side key range (Rs), and in the connected mode, the teacher side electronic music device ( MT = MD) is connected to the student-side electronic music device (MS = EM), and the performance guide unit performs performance guidance for the student-side key range (Rs) or the student-side electronic music device (MS). Various types of guide mechanisms can be adopted for the section. FIG. 2 shows an example of the performance of the electronic music apparatus according to one embodiment of the present invention and the appearance of the guide portion. The appearance 1 of FIG. 2 (1) is a push using a light emitting element such as an LED as a performance guide means. An example of appearance when a key to be locked is indicated is shown.

  In FIG. 2 (1 a), an LED guide lamp 16 L is arranged for each key in the vicinity of the keyboard 15 K of the performance operator 15. The keyboard 15K is divided into a low pitch range Rt and a high pitch range Rs with the split point as a boundary when the performance guide is performed in the continuous mode. The low pitch range Rt is called a teacher side key range, It is called student side key range. When the teacher performs an exemplary performance in the teacher-side key range Rt, in the student-side key range Rs, the pitch position corresponding to the key in the teacher-side key range Rt operated in the exemplary performance of the LED guide lamp 16L ( For example, an LED lamp provided corresponding to a key (referred to as a corresponding key) at the position of 3 octaves up lights up, and a performance instruction (also referred to as a performance guide) is given to the student to press the corresponding key. I do.

  Regarding the display of the split point, in the electronic music apparatus dedicated to the continuous mode, as shown in the figure, the characters “SPLIT POINT” and / or the split mark (baseball home) The base-shaped arrow) may be described in a fixed manner. However, in an electronic music apparatus having a continuous mode and a connected mode, a method of variably displaying characters and marks so that they appear only when the key range is divided is used. It is preferable to take.

  In FIG. 2 (1b), a key to be depressed is illuminated using built-in LED lamps 16E (not shown) incorporated in each key of the keyboard 15K to notify the student of the corresponding key. For example, each key of the keyboard 15K is formed of a material such as a translucent synthetic resin, and the LED light emitter 16E is stored in the lower part of the key or incorporated in the key. Is milky white and the black key is dark black. However, when the performance guide is given in the continuous mode, the corresponding key in the student key range Rs corresponds to the model performance in the teacher key range Rt. By turning on the built-in LED lamp 16E, the corresponding key itself is lit brightly to instruct the user to press the key.

  Appearance 2 in FIG. 2 (2) shows an example of appearance when a key to be pressed is instructed using the LCD display 16D as performance guide means. In this case, on the performance guide screen displayed on the display 16D, a keyboard image simulating the keyboard 15K to be guided is displayed, and the operation keys corresponding to the model performance in the teacher side key range Rt are highlighted with a circle or the like. Thus, a performance instruction is performed. The target to be guided may not be a full key, but a limited range such as the middle hit of the keyboard 15K or only the range of the student side area Rs may be simulated. Also, when the performance guide is performed in the continuous mode, as shown in the drawing, the bass range corresponding to the teacher side key range Rt is set as a gray fixed image, and the key is pressed only by half the high range corresponding to the student side key range Rs. You may be able to give instructions. However, in the electronic music apparatus dedicated to the connection mode or the electronic music apparatus having the continuous mode and the connection mode, when the performance guide screen is used in the connection mode, it is possible to make a key press instruction for the entire range of the performance guide screen. preferable.

  When the LCD display 16D is used as the performance guide means, the image displayed on the performance guide screen may be a musical score instead of the keyboard as shown in the upper left of FIG. In this case, on the staff, each note by the teacher's model performance is displayed in the order of performance as the corresponding note at the corresponding pitch position on the staff, and when the user presses the key corresponding to the corresponding note, the corresponding note is displayed. Is deleted from the staff, but the note remains displayed on the staff unless the user presses the key corresponding to the note. Regarding the position of the corresponding note in the performance progression direction, it is preferable that the corresponding note after that is moved forward (moved leftward) so that the corresponding note at the beginning is displayed at a certain position.

  Further, in the following example, the explanation of the performance guide will be made with respect to the case where a light emitting element such as an LED is used for the performance guide means to instruct the key to be pressed, but the same applies to other types of performance guide means. The performance guide can be realized.

[Performance guide in the continuous mode]
In the performance guide processing system according to one embodiment of the present invention, when the teacher plays a key in the teacher side key range Rt of the electronic music apparatus EM in the continuous mode, the predetermined guide lamp 16L in the student side key range Rs lights up. The performance guide is performed in such a manner that the corresponding key corresponding to the key played by the player is instructed and this lighting state is maintained until the student plays the corresponding key.

  FIG. 3 is a conceptual diagram of the performance guide in the continuous mode of the performance guide processing system according to one embodiment of the present invention. As shown in FIG. 3, the performance guide processing system includes a keyboard 15K that is divided into a teacher-side key range Rt and a student-side key range Rs, and a guide lamp 16L for each key of the keyboard 15K. Comparing the pitch value of the key pressing information based on the performance operation composed of the performance indicator 16 and the key pressing operation of the guide section A and the keyboard 15K with the pitch value of the predetermined split point, the key pressing information is A key range determination unit C for determining (determining) whether a key is pressed in the key range Rt or a key press in the student side key range Rs, and a key Kt at a certain pitch position in the teacher side key range Rt The teacher-side pitch information based on the operation of the key coincides with the student-side pitch information based on the operation of the key Ks at the same pitch position as the key Kt in the student-side key range Rt. Teacher-side pitch information and / or A musical tone that generates a musical tone signal based on a transpose section (also referred to as a pitch converting section) D that converts the pitch information of the student side, and key pressing information that includes the pitch information converted by the transpose section D. The teacher side pitch information from the signal generator B and the transpose unit D is accumulated in the buffer memory G (also referred to as “stacking”) E (also referred to as an accumulation processing unit) E, and the student side from the transpose unit D When the pitch information coincides with the first teacher side pitch information stored in the buffer memory G, the teacher side supplied from the deletion processing unit F and the stack processing unit E that deletes the teacher side pitch information from the buffer memory G A buffer that sequentially accumulates pitch information from the top address in the order of supply timing and shifts the information below the first address to the head address or less when the first teacher side pitch information is deleted by a deletion instruction from the deletion processing unit F Mori G, and the like performance guide control unit H controls the performance guide by lighting of guide lamps 16L in the performance indicator 16 in accordance with the stored contents with reference to the buffer memory G.

  The operation of the continuous mode will be described with a specific example. First, a teacher (instructor) and a student sit in front of an electronic keyboard instrument with a performance guide function, that is, an electronic music device EM. When the continuous mode function switch is turned on and the continuous function is turned on, the keyboard 15K is divided into two key ranges with a predetermined split point as a boundary, and one key range (for example, low pitch key range) is a teacher (instructor) Is set to the teacher-side key range Rt, and the other key range (in this example, the high pitch range) is set to the student-side key range Rs.

  In this setting process, the key range determination unit C sets a split point, which is a key range determination reference, for example, between the E3 key and the F3 key, and when the pitch information from the keyboard 15K is equal to or lower than E3, the teacher side It is determined that it is based on the key operation of the key range Rt, and when it is F3 or more, it is determined that it is based on the key operation of the student side key range Rt. Further, the transpose unit C converts the pitch information generated based on the key operation of the teacher-side key range Rt, and for example, increases the pitch by 3 octaves. In this example, the pitch information generated based on the key operation of the student-side key range Rt is not converted and is used as the pitch value as it is. That is, the F0 to E3 keys in the teacher side key range Rt correspond to the F3 to E6 keys in the student side key range Rt, respectively, and the pitch information based on the operations of the F0 to E3 keys and the F3 to E6 keys is The pitch is converted to represent the high F3 to E6, and the pitch values are aligned. In other words, the key Kt at a certain pitch position in the teacher side key range Rt = F0 to E3 and the key Ks at the same pitch position as the key Kt in the student side key range Rt = F3 to E6. The pitch information based on the operation of the keys Kt and Ks is converted to the same pitch value by the transpose unit C, and both pitch information after the pitch conversion is converted to the same tone value by the musical tone signal generation unit B. Generate a high tone signal. Of course, the pitch information based on the key operation in the teacher-side key range Rt may be used as it is, and the pitch information based on the key operation in the student-side key range Rs may be reduced by three octaves to align both pitch information. The pitch information based on the key operation in the teacher-side key range Rt may be increased by two octaves, and the pitch information based on the key operation in the student-side key range Rs may be shifted one octave to align both pitch information.

  Next, when the teacher plays a certain key Kt in the teacher side key range Rt, the pitch information based on the operation of the key Kt is converted into a value three octaves higher through the key range determination unit C and the transpose unit C. The pitch information that has been converted into pitches is supplied to the musical tone signal generation unit B, and a musical tone signal corresponding to the pitch information is generated and stored in the buffer memory G via the stacking processing unit E. . In accordance with the pitch information stored in the buffer memory G, the performance guide control unit H identifies a key played by the teacher in a predetermined guide lamp 16L in the performance indicator 16, that is, in the student side key range Rt. Then, the lamp 16L of the key (corresponding key) Ks corresponding to the key Kt (FIG. 2 (1a) black circle) is turned on.

  This lamp continues to be lit until the student plays the key Ks. That is, when the student plays the corresponding key Ks in the student side key range Rt, pitch information based on the operation of the key Kt is supplied to the musical tone signal generation unit B through the key range determination unit C and the transpose unit C. A tone signal corresponding to the pitch information is generated and supplied to the deletion processing unit F. When the pitch information that matches the head pitch information stored in the buffer memory G (that is, the same pitch) is supplied, the deletion processing unit F deletes the head pitch information from the buffer memory G. Therefore, the pitch information based on the fact that the teacher has played the key Kt coincides with the pitch information based on the fact that the student has played the key Ks, and is deleted from the buffer memory G. In response to this, the performance guide control unit H turns off the lamp 16L that has instructed the key depression of the corresponding key Ks.

  As described above, the lit guide lamp 16L is turned off when the student correctly plays the key Ks having the same positional relationship as the key Kt played by the teacher, but the teacher only releases the key Kt. Does not turn off. Further, the light is not turned off even when a student mistakenly plays a key whose positional relationship is different from the key Kt played by the teacher.

  The characteristics of the performance guide in this performance guide processing system can be summarized as follows: In this system, performance guide means comprising a guide lamp 16L such as an LED for each key of a keyboard 15K comprising a plurality of keys. In the continuous mode, the keyboard 15K is divided into teacher-side and student-side key ranges Rt and Rs. When the teacher performs a model performance in the teacher side key range Rt, pitch information by the model performance is sequentially accumulated in the buffer G through the stacking processing unit E, and the pitch information stored in the buffer G by the performance guide control unit H The guide lamp 16L for the corresponding key (corresponding key) is turned on based on the key, and the performance guide for the corresponding key is started. On the other hand, when the student operates the corresponding key in the student-side key range Rs (the pitch information corresponds to the pitch information of the model performance stored in the buffer G), the deletion processing unit F performs the model performance. Is deleted from the buffer G, and the performance guide control unit H turns off the guide lamp 16L and ends the performance guide for the corresponding key. In the connection mode, which will be described later, pitch information based on an exemplary performance from a teacher-side instrument (MD = MS) connected to a student-side instrument (EM = MT) by a signal line for pitch information is stored in the buffer G. As a result, the guide lamp 16L is turned on and the performance guide for the corresponding key is started. When the student's instrument is operated on the corresponding key, the pitch information is deleted from the buffer G, and the guide lamp 16L is turned off. Then, the performance guide for the corresponding key is ended.

  Further, in this system, key pressing information (note-on) is used as performance information for key pressing instructions. The key release information (note-off) is used in the musical tone signal generation unit B to mute the generated musical tone, but is not necessary for the key pressing instruction.

[Processing flow in an electronic music apparatus having a continuous mode]
In the performance guide processing system according to the embodiment of the present invention, the above-described performance mode performance guide can be performed in accordance with the performance guide processing program. 4 and 5 are flowcharts showing an example of processing in the electronic music apparatus having the continuous mode according to one embodiment of the present invention, and FIG. 4 shows the main processing flow.

  The main processing flow in FIG. 4 starts when the electronic music apparatus EM is turned on. First, in the first step M1, the CPU 1 performs initial settings and resets the settings of each unit to initial values. As a result, the setting of each key range for the keyboard 15K is reset, and the “normal mode” is set in the flag register on the RAM 2. In the next step M2, it is determined whether or not the flag set in the flag register is the “continuous fire mode”.

  When it is determined in step M2 that the flag is not in the continuous mode, that is, in the normal mode (M2 = NO), the process proceeds to step M3, where normal mode processing (normal music signal generation processing) is performed, and key division (C ) Or pitch conversion (D), in a normal processing mode, a musical tone signal is generated based on the performance operation of the performance operator 15 such as the keyboard 15K, or the performance data from the storage means 3, 4 etc. A musical tone signal is generated based on the basis. Next, in step M4, it is determined whether or not a continuous mode transition operation has been performed. If a continuous mode transition operation has not been performed (M4 = NO), the process returns to step M2. When a continuous mode transition operation for operating the continuous mode switching switch in the setting operator 17 is performed (M4 = YES), the process proceeds to Step M5, and the timbres of each key range (for example, similar timbres, but clearly identified). Set the pitch conversion amount for the teacher-side and student-side pitch information in the transpose section D, and clear the buffer memory G so that the pitches of each key range are aligned. Etc. Set the initial conditions required in the continuous mode. In step M6, the flag register mode is set to the continuous mode, and then the process returns to step M2.

  When it is determined in step M2 that the flag is in the continuous mode (M2 = NO), the process proceeds to step M7 to activate each of the function units C to H related to the performance guide display described in the conceptual diagram of FIG. In accordance with the conditions set in M5, the continuous shot mode process shown in FIG. 5 is performed. Next, in step M8, it is determined whether or not a normal mode transition operation has been performed. When the normal mode transition operation has not been performed (M8 = NO), the process returns to step M2. When the normal mode transition operation for operating the normal mode transition switch in the setting operator 17 is performed (M8 = YES), the process proceeds to step M9, and the conditions and performance guide display functions set for each key range are reset. . In step M10, the flag register mode is set to the normal mode, and then the process returns to step M2. When returning to step M2, the above-described processes of steps M2 to M10 are repeated until the power is turned off.

  FIG. 5 is a flowchart showing the procedure of the continuous shot mode process performed in step M7 of FIG. When the continuous mode processing is started, it is determined whether or not the key pressing operation is performed in the first step F1. When the key pressing operation is performed (F1 = YES), the key pressing is compared with the split point value in step F2. It is determined whether or not the operated position is in the teacher side key range (bass pitch range) Rt.

  When it is determined in step F2 that the key pressing position is in the teacher side key range Rt (F2 = YES), the process proceeds to step F3, and the pitch of the key pressing information is set to the teacher side pitch set in step M5. Transpose (pitch conversion) is performed with the pitch conversion amount with respect to, and in the next step F4, a tone generation instruction is issued to the musical tone signal generation unit B with the transposed key press information. In step F5, at least the pitch information of the transposed key press information is accumulated in the buffer memory G.

  On the other hand, when it is determined that the key pressing position is in the student side key range Rs (F2 = NO), the process proceeds to step F6, and the pitch conversion of the key pressing information with respect to the student side pitch set in step M5 is performed. In step F7, the musical tone signal generation unit B is instructed to generate a sound by using the transposed key press information. In step F8, the pitch of the transposed key press information is compared with the pitch of the first key press information loaded in the buffer G. Is deleted from the buffer G.

  After the stacking process in step F5 or the deletion process in step F8, the process proceeds to step F9, and the performance of the LED or the like is performed so as to instruct key pressing of the key corresponding to the pitch information currently stored in the buffer G. The display on the indicator 16 is updated. When it is determined in step F1 that no key pressing operation has been performed (F1 = NO), or after the display update processing of the performance indicator 16 in step F9, in step F10, each key range is changed according to the user operation. Performs other processing such as volume, localization, and tone settings. After other processing in step F10 or when there is no user operation and step F10 is passed, the process returns to step M8 of the main processing (FIG. 4).

[Guide for performance in connected mode]
In the performance guide processing system according to the embodiment of the present invention, another electronic music device played by the teacher is connected to the electronic music device EM to set the operation mode to a connected mode (also referred to as “teaching mode”). When the player plays a key with another electronic music device, the corresponding guide lamp 16L in the electronic music device EM is turned on to indicate the corresponding key corresponding to the key played by the teacher, and this lighting state remains until the student plays the corresponding key. The performance guide can be performed in a manner of maintaining the above.

  FIG. 6 is a diagram for explaining a configuration of a performance guide processing system having a connection mode according to an embodiment of the present invention. FIG. 6 (1) shows an external appearance of the system configuration in the case of having a connection mode. . In this system example, two electronic musical instruments are connected by a MIDI cable, and performance information is sent to one electronic musical instrument from the other electronic musical instrument.

  One electronic musical instrument is called a student apparatus MS because the electronic music apparatus EM shown in FIG. 1 is used and is played by a student. Further, as the other electronic musical instrument serving as the counterpart device of the student side device MS, an electronic music device shown by another MIDI music device MD in FIG. 1 is used and has the same hardware configuration as the electronic music device EM. A performance indicator control circuit and a performance indicator are not required. Since the other electronic musical instrument MD is played by the teacher, it is called a teacher-side device MT. In the following example, a musical tone signal generation unit B is provided to play an exemplary performance by the teacher-side device MT (= MD). However, the musical tone signal generator B is not necessary when the student side apparatus MS (= EM) plays an exemplary performance.

  In the connected mode, as shown in FIG. 6 (1), the performance guide means (performance indicator) 16 has LEDs arranged corresponding to the keys in the vicinity of the keyboard 15K, as in FIG. 2 (1a). In the student apparatus MS, the lighting of the guide lamp 16L is controlled according to the performance information from the teacher apparatus MT, and a performance instruction is given. Of course, the performance instruction may be given in another manner as shown in FIG. 2 (1b) or FIG. 2 (2).

  FIG. 6B is a conceptual diagram of the performance guide in the connection mode of this performance guide processing system. As shown in FIG. 6 (2), this performance guide processing system is connected to a teacher side device MT (= MD) having a keyboard and a musical tone signal generator, an LED, etc. for each key of the keyboard 15K and the keyboard 15K. The student side apparatus MS provided with the performance operation and the guide part A composed of the performance indicator 16 provided with the guide lamp 16L is connected. The student-side device MS further stores (stacks) teacher-side pitch information from the teacher-side device MT in the buffer memory G, and bufferes student-side pitch information from the keyboard 15K. When it coincides with the first teacher side pitch information stored in the memory G, the teacher side pitch information supplied from the deletion processing unit F and the stacking processing unit E for deleting the teacher side pitch information from the buffer memory G is supplied. Buffer memory G, buffer memory G that sequentially accumulates from the top address in the order of timing and shifts the information below the next address below the top address when the top teacher side pitch information is deleted by the deletion instruction from the deletion processing unit F , And a function unit such as a performance guide control unit H for controlling a performance guide by turning on a guide lamp 16L in the performance indicator 16 according to the stored contents.

  In this way, in the connected mode, compared to the continuous mode described in FIG. 3, there is no key range determination and transposition associated with key range division, teacher side pitch information from the teacher side device MT, and students from the keyboard 15K. The functional units E to H operate in the same manner as in the continuous shooting mode, except that the side pitch information is directly supplied to the stacking processing unit E and the deletion processing unit F, respectively.

[Processing flow in a performance guide processing system having a connection mode]
In the performance guide processing system according to one embodiment of the present invention, the performance guide in the connection mode described above can be performed according to the performance guide processing program. 7 and 8 are flow charts showing processing examples in the performance guide processing system having the connection mode according to one embodiment of the present invention.

  The teacher-side device MT starts processing upon power-on, and performs initial setting in the first step T1, for example, “normal mode” is set in the flag register on the RAM. In the next step T2, the learning mode (in the case of the learning mode start notification) or the normal mode is stored in the flag register in accordance with the mode notification from the student apparatus MS (notification of the start or end of the “learning mode” (= connection mode)). (In the case of learning mode end notification) is set, and if there is no mode notification, step T2 is passed. In the subsequent step T3, it is determined whether or not a key pressing operation has been performed.

  If it is determined that there has been a key pressing operation (T3 = YES), a tone generation instruction is given to the musical tone signal generation unit B in step T4, and the process proceeds to step T5. In step T5, it is determined whether or not the flag set in the flag register is the learning mode. If the learning mode is set (T5 = YES), the key press information is sent to the student side device MS in step T6. Send to.

  When it is determined in step T3 that there is no key pressing operation (T3 = NO), when it is determined in step T5 that the normal mode is set (T5 = NO), or after the key pressing information transmission processing in step T6 Returns to step T2 and repeats the processes of steps T2 to T6 described above until the power is turned off.

  The student apparatus MS starts processing when the power is turned on, and performs initial setting in the first step S1, for example, the “normal mode” is set in the flag register on the RAM 2, and the buffer memory G is cleared. In the next step S2, it is determined whether or not the flag set in the flag register is the learning mode.

  If the normal mode is set (S2 = NO), normal mode processing (normal music generation processing) is performed in step S3. After the normal mode process, the process proceeds to step S4, where it is determined whether or not a learning mode transition operation has been performed, and when there is a learning mode transition operation for operating the learning mode transition switch in the setting operator 17 (S4). First, in step S5, the teacher side device MT is notified of the start of the learning mode. Next, the display contents of the buffer memory G and the performance indicator 16 are cleared in step S6, and the learning mode is set in the flag register in step S7. Then, when there is no learning mode transition operation (S4 = NO), or after the learning mode flag is set in step S7, the process returns to step S2.

  On the other hand, when it is determined in step S2 that the learning mode is set (S2 = YES), in step S8, the respective function units E to H relating to the performance guide display described in the conceptual diagram of FIG. 6B are activated. The learning mode process (also referred to as a connected mode process) shown in FIG. 8 is performed. In the next step S9, it is determined whether or not a normal mode transition operation has been performed. When there is a normal mode transition operation (S9 = YES), first, the teacher side device MT is notified of the end of the learning mode in step S10. To do. Next, the display content of the performance indicator 16 is cleared in step S11, and the normal mode is set in the flag register in step S12. Then, when there is no normal mode transition operation (S9 = NO) or after the normal mode flag is set in step S12, the process returns to step S2. Moreover, when returning to step S2, the process of step S2-S12 mentioned above is repeated until a power supply is turned off.

  FIG. 8 is a flowchart showing the procedure of the learning mode process (connection mode process) performed in step S8 of FIG. When the learning mode process is started, it is determined in the first step L1 whether or not the key pressing information has arrived from the teacher-side apparatus MT. If the key pressing information has arrived (L1 = YES), the process proceeds to step L2. In step L2, at least the pitch information of the key depression information received from the teacher side device MT is accumulated in the buffer memory G.

  When it is determined in step L2 that the key pressing information has not arrived from the teacher side device MT (L1 = NO), it is determined in step L3 whether or not the key pressing operation has been performed on the key of the keyboard 15K in the student side device MS. . Here, when there is a key pressing operation (L3 = YES), first, in step L4, a musical tone signal generation unit B is instructed to generate sound according to the key pressing information based on the key pressing operation, and in the next step L5, The pitch of the key depression information based on the key depression operation on the student side device MS is compared with the pitch of the first key depression information loaded in the buffer G. If the pitch is the same, the first key depression information Is deleted from the buffer G.

  After performing the pitch information accumulation process in step L2 or after deleting the same pitch information in step L5, the process proceeds to step L6 and corresponds to the pitch information currently stored in the buffer G. The display content of the performance indicator 16 is updated so as to instruct key pressing.

  When it is determined in step L3 that there is no key pressing operation (L3 = NO) or after the display update process in step L6, the process proceeds to step L7, and other settings such as volume, localization, tone color setting, etc. according to the user operation After the other processes, the process returns to step S9 in FIG.

[Various Embodiments]
The preferred embodiment of the present invention has been described above with reference to the drawings. However, this is merely an example, and the present invention can be variously modified without departing from the spirit of the invention. For example, in the embodiment, an electronic musical instrument combined with an electronic performance guide function has been described as an electronic music device, but an electronic pitch information detection function and a performance guide function combined with a natural instrument such as a piano. May be an electronic music device.

  Further, in the embodiment, considering the order when deleting pitch events from the buffer G, the events on the teacher side are stacked in the buffer G from the top address in the order of timing, and the key-pressing event and the buffer on the student side are loaded. Although the pitch is compared with the first event on G, an event having the same pitch may be simply deleted. That is, the teacher side event loaded in the buffer G is searched for the same pitch as that of the student side key pressing event, and when it is searched, the teacher side event is deleted. Thereby, the structure of the function parts EH can be simplified.

  For key division in the continuous mode, for example, there is a confusing zone that is not included in any key range between the teacher side key range and the student side key range, and that is not involved in musical tone generation or performance instructions. The key division may be three or more formally, but in this case as well, the function of dividing into two in the teacher side key range and the student side key range remains the same. Further, it is not necessary to limit which key range is for the teacher and which key range is for the student. For example, the bass key range may be on the student side.

  The communication method for realizing the function of the connection mode may be MIDI, but may be another communication method. The connection mode function is set from the student side in the embodiment, but may be specified from the teacher side or both. The apparatus that realizes the function of the connection mode may be determined in advance as a teacher-dedicated apparatus or a student-dedicated apparatus, or may be any one.

  For the performance guide, examples of display control that control lighting of the LED near the keyboard, lighting of the key to be pressed, lighting of the keyboard image on the display and lighting on the staff score image are shown. The key itself may be mechanically controlled by vibrating or slightly sinking.
