In this mode, a key range setting screen as shown in FIGS. 21 (1) to 21 (5) is displayed (step C3), and the number of key ranges corresponding to RANGE is displayed (step C4). When the number of keys of the electronic keyboard instrument 20 is 88, the value of RANGE is set to 88 in the value switch process of FIG. 18, and therefore, as shown in FIG. The key flashes and “88 Keys” is displayed. When the value of RANGE is 76, as shown in FIG. 21 (2), 76 keys in the keyboard display area blink, and “76 Keys” is displayed. Similarly, when the RANGE values are 73, 61, and 49, the display screen shown in FIGS. 21 (3), (4), and (5) is obtained.
[0034]
If it is not the key range setting mode in step C2 of the flow of FIG. 19, it is determined whether or not it is the navigation channel setting mode (step C5). In this mode, a navigation channel setting screen as shown in FIG. 22 is displayed (step C6), and a navigation channel is displayed (step C7). The example of FIG. 22 is a case where there are four navigation channels. Therefore, “4 Navi.ch” is displayed.
[0035]
When the function flag is 0 (performance mode) in step C1 of the flow of FIG. 19, in the flow of FIG. 20, as shown in FIGS. 23 (1) to (5), the performance screen corresponding to the performance state is shown. Is displayed (step C8). For example, in the case of normal playback, since channels 1 to 16 are set as channels for automatic performance, as shown in FIG. 23 (1), all channel number marks are highlighted and the channel that is sounding. The mark at the position corresponding to the channel number (1 and 4 in this example) is lit.
[0036]
In the flow of FIG. 20, it is determined whether or not the guide part flag is 1 (step C9). If this flag is 1, the guide part channel is displayed (step C10). That is, in the case of guide part playback, as shown in FIG. 23 (2), only the channel number mark of the channel of the solo part to be automatically played (in this example, 4) is highlighted, and the channel number of the channel that is sounding is displayed. The mark corresponding to is lit. In Easy (1), Easy (2), and Normal lesson modes, since it is minus one performance, as shown in FIGS. 23 (3) and (4), channels other than the part channel for practice performance are used. Highlight the number. In the performance stop state, since there is no channel that is sounding, any channel number mark is turned off as shown in FIG.
[0037]
In the flow of FIG. 20, it is determined whether or not STF is 1 (automatic performance) (step C11). If this flag is 1, the key display is based on the note event in the MIDI output buffer. Perform (Step C12). Next, it is determined whether or not the UP over flag is 1 (high range over) (step C13). If this flag is 1, FIG. 23 (1), (3), (4), As shown in (5), the UP segment blinks (step C14). Further, it is determined whether or not the DOWN over flag is 1 (low range over) (step C15). If this flag is 1, the DOWN segment is blinked as shown in FIG. 23 (2). (Step C16).
[0038]
24 to 33 are flowcharts of the sequence process in step A5 of FIG. First, it is determined whether or not the STF is 1 (automatic performance) (step D1). If this flag is 1, it is determined whether or not the minimum resolution time has elapsed (step D2). The minimum resolution time is expressed by an integer (for example, 24) of the time length of a quarter note. Therefore, when the tempo is 120 and the time length of the quarter note is 500 ms, the minimum resolution time is about 21 ms. If the minimum resolution time has not elapsed, it is determined whether or not the wait flag is 0 (step D3). If this flag is 0 and the key is not waiting for key depression, this flow is terminated.
[0039]
On the other hand, when the minimum resolution time has elapsed, it is determined whether or not the value of the register STEP is 0 (normal automatic performance mode) or 3 (normal lesson mode without waiting for key depression) (step D4). When the STEP value is 0 or 3, the value of the reproduction counter is incremented by the elapsed minimum resolution time (step D5). Then, it is determined whether or not the STEP value is 0 (step D6). If this value is 0, normal playback processing is executed (step D7). Then, the process returns to the main flow.
[0040]
FIG. 25 shows a flow of normal reproduction processing. In this flow, it is determined whether or not the designated music data is on the FD (floppy disk) (step D8). If there is no data, this flow is terminated. If there is data, MEM [AP], which is delta time data of the address AP of the FD, is set in the register ΔT (step D9). That is, the start time of the next event is set to ΔT. Then, it is determined whether or not the value of the reproduction counter is equal to or greater than the addition value of the value of TIME and the value of ΔT (step D10). As described above, since the value of the playback counter is time data that accumulates every time the minimum resolution time elapses, if the value of the playback counter is small, the start time of the next event has not yet been reached. Exit.
[0041]
If the value of the playback counter is equal to or greater than the sum of the value of TIME and the value of ΔT, that is, if the value of the playback counter has reached the start time of the next event, the value of ΔT is added to the value of TIME. The value is added (step D11), the value of the address pointer AP of the music data is incremented (step D12), and event data is designated. Then, the event data MEM [AP] is set in the register EVENT (step D13). Next, it is determined whether or not the guide part flag is 1 (solo part automatic performance) (step D14). If this flag is 1, it is determined whether or not the EVENT channel and the guide part channel are the same (step D15).
[0042]
If the guide part flag is 0, or if the EVENT channel and the guide part channel are the same, the EVENT data is stored in the tone generation buffer (step D16). After the data is stored, or when the EVENT channel and the guide part channel are different in step D15, the AP value is incremented (step D17), the process proceeds to step D8, and the processes up to step D17 are performed. repeat. Each time the reproduction counter value reaches the start time of the event data, the event data is stored in the sound generation processing buffer. If there is no music data to be read out in step D8 and the music is finished, the process returns to the main flow.
[0043]
In step D6 of the flow of FIG. 24, when the value of STEP is not 0 but 3 (lesson mode without waiting for key depression), the value of the playback counter reaches the value of the notice flashing counter in the flow of FIG. It is determined whether or not (step D18). In the notice blinking counter, time data for blinking the light emitting element in order to learn to press the electronic keyboard instrument 20 is set. Therefore, when the value of the reproduction counter that accumulates the value every minimum resolution time reaches the value of the notice flashing counter, it is when the current time reaches the key pressing timing time. Therefore, it is necessary to change the light emitting element from blinking to lighting. For this reason, the notice flashing counter is cleared (step D19). After clearing this counter, or when the value of the playback counter has not yet reached the value of the notice flashing counter, the notice note detection process is executed when the STEP value is 3 (lesson mode not waiting for key depression) ( Step D20). That is, prefetching of data is performed. Next, a music data reading process is executed (step D21). Then, the process returns to the main flow.
[0044]
FIG. 27 is a flow of notice note detection processing (STEP 3) in step D20 of FIG. It is determined whether or not song data still exists in the FD (step D22). If there is no data, that is, when the song is finished, this flow is finished. If there is still data, the delta time data MEM [YAP] of the notice address pointer YAP is set to ΔT (step D23), and the event data of the next notice address pointer (YAP + 1) is set to EVENT (step D24). ). Next, it is determined whether or not the EVENT channel and the guide part channel are the same (step D25).
[0045]
If they are not the same, the value of ΔT is added to the value of the notice flashing counter (step D26A), and 2 is added to the value of YAP (step D26B). That is, the next notice note data is designated. Next, the process proceeds to step D22 to determine whether there is designated data. The loop from step D22 to step D26B is repeated until EVENT of the same channel as the channel of the guide part is detected. When EVENT of the same channel is detected in step D25, it is determined whether or not the RANGE of the note of the EVENT is within the key range (step D27).
[0046]
If it is within the key range, the EVENT note is stored in the notice flashing buffer (step D28). That is, the light emitting element corresponding to the key to be pressed is stored as data for blinking in advance. If the RANGE of the EVENT note is not within the key range, the notice flashing buffer is cleared (step D29). After storing the note in the warning flashing buffer or after clearing the warning flashing buffer, the value of ΔT is added to the value of the warning flashing counter (step D30), and 2 is added to the value of YAP (step D31). . That is, the next notice note data is designated. And it transfers to step D21 of the flow of FIG.
[0047]
FIG. 28 is a flowchart of the music data reading process in step D21 of FIG. It is determined whether or not the designated music data is in the FD (step D32A). If there is no data, this flow is terminated. If there is data, MEM [AP], which is delta time data of the address AP of the FD, is set in the register ΔT (step D32B). Then, it is determined whether or not the value of the reproduction counter is equal to or greater than the addition value of the value of TIME and the value of ΔT (step D33). When the value of the reproduction counter is small, since the start time of the next event has not been reached yet, this flow is ended.
[0048]
If the value of the playback counter is equal to or greater than the sum of the value of TIME and the value of ΔT, that is, if the value of the playback counter has reached the start time of the next event, the value of ΔT is added to the value of TIME. The value is added (step D34), the value of the address pointer AP of the music data is incremented (step D35), and event data is designated. Then, the event data MEM [AP] is set in the register EVENT (step D36). Then, the EVENT data is stored in the sound generation processing buffer (step D37). Next, the value of AP is incremented (step D38), the process proceeds to step D32A, and the process up to step D38 is repeated. Each time the reproduction counter value reaches the start time of the event data, the event data is stored in the sound generation processing buffer. If there is no music data to be read in step D32A and the music is finished, the process returns to the main flow.
[0049]
If the STEP value is 1 (easy (1) lesson) or 2 (easy (2) lesson) in step D4 of the sequence processing in FIG. 24, the notice flashing counter value is reproduced in the flow of FIG. It is determined whether or not the counter value is the same (step D39). When these values are not the same, that is, when the light emitting element of the electronic keyboard instrument 20 is blinking, the next key depression notice is performed, but the value (time) of the reproduction counter is the value of the notice blink counter (flashing end time). If the key press start time has not yet been reached, it is determined whether or not there is data in the MIDI key press request buffer (step D40).
[0050]
If there is data in this buffer, that is, if there is note data to be pressed on the electronic keyboard instrument 20 side, it is determined whether or not there is data in the MIDInewON buffer (step D41). When there is data in this buffer, that is, in the electronic keyboard instrument 20, when the key is pressed even if the key pressing start time has not yet been reached, the note data by the key pressing is stored in the MIDInewON buffer. The In this case, it is determined whether or not the STEP value is 2 (easy (2) lesson) (step D42). If the STEP value is 2 and the key-press waiting lesson mode is set, it is determined whether or not the note data in the MIDI key-request buffer matches the note data in the MIDInewON buffer (step D43). That is, it is determined whether or not the note data of the key press request matches the note data of the actual key press.
[0051]
If the note data in both buffers do not match, it is not recognized as a key depression, and the value of the reproduction counter is incremented by the minimum resolution time that has elapsed (step D2 in FIG. 24) (step D44). If there is no data in the MIDI key press request buffer in step D40, that is, the key range is over, or if there is no data in the MIDInewON buffer in step D41, that is, no key is pressed, playback is performed in step D44. Increment the counter value. Next, it is determined whether or not the notice flashing buffer has been cleared (step D45). If this buffer is cleared, the notice note detection process in the easy (1) lesson and the easy (2) lesson is executed (step D46). That is, prefetching of data is performed. After the advance note detection process (STEP 1 and 2) or when there is data in the advance blink buffer in step D45, the music data reading process shown in the flow of FIG. 28 is executed (step D47). Then, the process returns to the main flow.
[0052]
If the STEP value is 1 in step D42 and the key is in the key-waiting lesson mode, or if the note data in the MIDI key press request buffer matches the note data in the MIDInewON buffer in step D43. Is a case where the key is pressed even though the key pressing start time has not yet been reached. In this case, in the flow of FIG. 30, the value of the reproduction counter is updated to the value of the notice flashing counter (step D48). That is, in order to advance the current time, which is the value of the reproduction counter, to the key pressing start time, the value is changed to the value of the notice flashing counter. Then, 1 (fast forward mode) is set in the fast forward mode flag (step D49). Next, the music data reading process shown in the flow of FIG. 28 is executed (step D50). That is, in this case, the music data of the time difference obtained by advancing the current time is read in the fast-forward mode.
[0053]
In step D39 of FIG. 29, when the value of the notice flashing counter matches the value of the reproduction counter, that is, when the key pressing start time of the note in the key range is reached or the sounding time of the note outside the key range is reached. In step D51 of FIG. 30, it is determined whether or not there is data in the MIDI key press request buffer (step D51). If there is no data in this buffer, it is out of the key range, so the music data reading process shown in the flow of FIG. 28 is executed (step D50). That is, in this case, since the key depression instruction cannot be given, the song data is read in order to perform only the sound generation.
[0054]
When the music data reading process in step D50 is completed, the MIDI key press request buffer is cleared (step D52), and the notice flashing buffer is cleared (step D53). Then, the notice note detection process in the easy (1) lesson and the easy (2) lesson is executed (step D54). Next, it is determined whether or not the fast-forward mode flag is 0 (step D55). If this flag is 0, the value of the reproduction counter is incremented by the elapsed minimum resolution time (step D2 in FIG. 24) (step D56). Then, the process returns to the main flow. When the fast-forward mode flag is 1, since the value of the reproduction counter is updated to the value of the notice flashing counter in step D48, the process returns to the main flow without incrementing the reproduction counter.
[0055]
In step D51 of FIG. 30, when there is data in the MIDI key press request buffer, that is, when the key pressing start time corresponding to the flashing light emitting element in the electronic keyboard instrument 20 is reached, the flow of FIG. Then, it is determined whether or not the wait flag is 0 (step D57). If this flag is 0, the music data reading process shown in FIG. 28 is executed (step D58), and 1 (key press waiting mode) is set to the wait flag (step D59). Next, the notice flashing buffer is cleared (step D60). After the buffer is cleared or when the wait flag is 1 in step D57 or step D3 in FIG. 24, it is determined whether or not there is data in the MIDInewON buffer (step D61). If there is no data, the key range is over, so there is no need to wait for a key press and the process returns to the main flow.
[0056]
If there is data in the MIDInewON buffer, it is determined whether or not the STEP value is 2 (easy (2) lesson mode) (step D62). If this value is 2 and the key pressing waiting mode is correct, it is determined whether or not the note in the MIDI key press request buffer matches the note in the MIDInewON buffer (step D63). If the notes in the two buffers do not match, that is, if the note of the key press request is different from the actually pressed note, the process returns to the main flow. If the STEP value is 1 in step D62 and the key is in the key press waiting mode, or if the notes in both buffers match in step D63, the wait flag is set to 0 (step D64), The MIDI key press request buffer is cleared (step D65). Then, the process proceeds to step D54 in FIG. 30 to execute the notice note detection process (STEP 1 and 2).
[0057]
32 and 33 are flowcharts of the notice note detection processing (STEP 1 and 2) in step D46 of FIG. 29 and step D54 of FIG. In this flow, the song data of the FD (floppy disk) is searched to pre-read the notice note. It is determined whether or not there is song data in the FD (step D66), and if there is no data, that is, when the song is finished, this flow is finished. If there is data, the delta time data MEM [YAP] of the notice address pointer YAP is set to ΔT (step D67), and the event data of the next notice address pointer (YAP + 1) is set to EVENT (step D68). . Next, it is determined whether or not the EVENT channel and the guide part channel are the same (step D69).
[0058]
If they are not the same, the value of ΔT is added to the value of the notice flashing counter (step D70), and 2 is added to the value of YAP (step D71). That is, the next notice note data is designated. Next, the process proceeds to step D66 to determine whether or not there is designated data. Then, the loop of step D66 to step D71 is repeated until EVENT of the same channel as the channel of the guide part is detected. When EVENT of the same channel is detected in step D69, it is determined whether or not RANGE of the note of the EVENT is within the key range (step D72).
[0059]
If it is within the key range, the EVENT note is stored in the notice flashing buffer (step D73A). That is, the light emitting element corresponding to the key to be pressed is stored as data for blinking in advance. Also, the EVENT note is stored in the MIDI key press request buffer (step D73B). If the RANGE of the EVENT note is out of the key range in step D72, the notice flashing buffer is cleared (step D74). After clearing the warning flashing buffer or storing a note in the MIDI key press request buffer in step D73B, add ΔT to the warning flashing counter value (step D75) and add 2 to the YAP value. (Step D76). That is, the next notice note data is designated. Then, 1 is set in the register of the number of pronunciations (step D77).
[0060]
Next, it is determined whether or not there is data at the address designated by YAP (step D78). If there is no data, this flow is terminated. If there is data, the delta time data MEM [YAP] of the notice address pointer YAP is set to ΔT (step D79), and the event data of the next notice address pointer (YAP + 1) is set to EVENT (step D80). . Next, it is determined whether or not the value obtained by adding the value of ΔT to the value of the notice flashing counter is within the value obtained by adding the predetermined value α to the value of the notice flashing counter (step D81). The predetermined value α is a threshold value for determining whether or not the note pre-read and set to EVENT in the music data having the sequence data structure is a chord note to be pronounced at the same time as the previously read note. If the value obtained by adding the value of ΔT to the value of the warning flashing counter exceeds the value obtained by adding the predetermined value α to the value of the warning flashing counter, the EVENT note does not constitute a chord with the previous note. This flow is finished.
[0061]
If the value obtained by adding the value of ΔT to the value of the notice flashing counter is within the value obtained by adding the predetermined value α to the value of the notice flashing counter, the note of EVENT is the note that composes the previously read note and the chord. Therefore, in the flow of FIG. 33, it is determined whether or not the EVENT channel and the guide part channel are the same (step D82). If the channels are not the same, this flow ends. If the channels are the same, it is determined whether or not the number of sounds obtained by adding 1 to the current number of sounds set in the sound number register is within the maximum number of sounds (step D83). If the number of pronunciations obtained by adding 1 to the current number of pronunciations exceeds the maximum number of pronunciations (index), the latest note set in EVENT at step D80 in FIG. 32 is pressed simultaneously with the previous plurality of notes. This flow is finished because it cannot be pronounced.
[0062]
If the current number of pronunciations plus one is within the maximum number of pronunciations, the latest note set in EVENT can be pressed simultaneously with multiple previous notes, so that the pronunciation number register The value is incremented by 1 (step D84). Next, it is determined whether or not the RANGE of the note is within the key range (step D85), and if it is within the key range, the EVENT note is stored in the notice flashing buffer (step D86), and the EVENT note is pressed by MIDI. Store in the key request buffer (step D87). Next, the value of ΔT is added to the value of the notice flashing counter (step D88). Then, the YAP address is incremented by 2 (step D89), and the next event data is designated. Then, the process proceeds to step D78 in FIG. 32 to determine whether there is the designated data. If there is data, the loop from step D78 to step D89 is repeated.
[0063]
FIG. 34 is a flow of transmission data creation processing in step A6 of the main flow of FIG. It is determined whether or not there is data in the pronunciation processing buffer (step E1). If there is data, it is determined whether or not the data is a note-on or note-off event (step E2). If it is a note event, it is determined whether or not the STEP value is 0 (normal automatic performance) (step E3). If the value of STEP is 0, or if the data in the sound generation processing buffer is not a note event, it is determined whether or not the event channel and the guide part channel are the same (step E4).
[0064]
If the two channels are the same, the event channel is changed to the navigation channel (step E5). If the two channels are different, it is determined whether or not the event channel and the navigation channel are the same (step E6). If the two channels are the same, the event channel is changed to the guide part channel (step E7). Then, the event is transferred to the MIDI output buffer (step E8). For example, as shown in FIG. 35, when the guide part channel of the song data stored in the FD is 8 channels and the navigation channel is 4 channels, events of 4 channels are transferred to 8 channels of the MIDI output buffer, and 8 Channel events are transferred to the 4 channels of the MIDI output buffer. In step E4 and step E6, if the event is neither a guide part channel nor a navigation channel, the event is transferred to the same channel of the MIDI output buffer as shown in FIG.
[0065]
In step E3, if the STEP value is not 0, it is determined whether or not the STEP value is 3, that is, whether or not the lesson mode does not wait for key depression (step E9). If this value is 3, STEP (3) reproduction processing is executed (step E10). If this value is not 3, that is, 1 or 2, STEP (1, 2) reproduction processing is executed (step E11). After the event is transferred to the MIDI output buffer in step E8, or after the reproduction process is executed in step E10 or E11, the process proceeds to step E1 to determine the presence / absence of data in the sound generation process buffer. When there is data, the above steps are repeated. When all the data in the sound generation processing buffer is processed and there is no data, the fast-forward mode flag set to 1 is set to 0 (step E12), and the main flow is performed. Return to.
[0066]
36 to 38 show the flow of STEP (1, 2) reproduction processing in step E11 of FIG. In FIG. 36, it is determined whether or not the event note is within the RANGE key range (step E13). If the event note is within the RANGE key range, it is determined whether or not the event channel and the guide part channel are the same. A determination is made (step E14). If the channels are the same, it is determined whether or not the event is a note-on event (step E15). If it is a note-on event, it is determined whether or not the fast-forward mode flag is 0 (step E16). If this flag is 0 and the fast-forward mode is not set, the velocity value of the event is changed to 1 (minimum value) (step E17).
[0067]
After changing the velocity value, or when the event is not a note-on event in step E15, that is, a note-off event, the channel of the event is changed to a navigation channel (step E18). Then, the event is transferred to the MIDI output buffer (step E19). After the event is transferred or when the fast-forward mode flag is 1 (fast-forward mode) in step E16, the process returns to step E1 in the flow of FIG.
[0068]
In step E13 of FIG. 36, if the note of the event is not within the RANGE key range, it is determined whether or not the note is outside the RANGE high-frequency range (step E20). If it is on the high sound range side, 1 is set to the UP over flag (step E21). If it is not the high sound range side, that is, if it is the low sound range side, 1 is set to the DOWN over flag (step E22).
[0069]
If the event channel and the guide part channel are not the same in step E14, it is determined in the flow of FIG. 37 whether or not the event channel and the navigation channel are the same (step E23). If the channels are the same, it is determined whether or not the fast-forward mode flag is 0 (step E24). If this flag is 0, the event channel is changed to the guide part channel (step E25), and the event is transferred to the MIDI output buffer (step E26). After the event is transferred or when the fast-forward mode flag is 1 (fast-forward mode) in step E24, the process returns to step E1 in the flow of FIG.
[0070]
In step E23, if the event channel and the guide part channel are not the same, that is, if the event channel is different from the navigation channel and the guide part channel, it is determined whether or not the fast-forward mode flag is 0 ( Step E27). If this flag is 0, the event is transferred to the MIDI output buffer (step E28). After the event is transferred or when the fast-forward mode flag is 1 (fast-forward mode) in step E27, the process returns to step E1 in the flow of FIG.
[0071]
After the UP over flag or the DOWN over flag is set to 1 in step E21 or step E22 in FIG. 36, it is determined in the flow in FIG. 38 whether the event channel and the guide part channel are the same. (Step E29). If the channels are the same, it is determined whether or not the fast-forward mode flag is 0 (step E30). If this flag is 0 and the fast-forward mode is not set, the event channel is changed to the navigation channel (step E31). Then, the event is transferred to the MIDI output buffer (step E32). After the event is transferred or when the fast-forward mode flag is 1 (fast-forward mode) in step E30, the process returns to step E1 in the flow of FIG.
[0072]
If the event channel and the guide part channel are different in step E29, it is determined whether or not the event channel and the navigation channel are the same (step E33). If the channels are the same, it is determined whether or not the fast-forward mode flag is 0 (step E34). If this flag is 0, the channel of the event is changed to the channel of the guide part (step E35), and the event is transferred to the MIDI output buffer (step E36). After transferring the event, or when the fast-forward mode flag is 1 (fast-forward mode) in step E34, the process returns to step E1 in the flow of FIG.
[0073]
In step E33, if the event channel and the guide part channel are not the same, that is, if the event channel is different from the navigation channel and the guide part channel, it is determined whether or not the fast-forward mode flag is 0 ( Step E37). If this flag is 0, the event is transferred to the MIDI output buffer (step E38). After the event is transferred or when the fast-forward mode flag is 1 (fast-forward mode) in step E37, the process returns to step E1 in the flow of FIG.
[0074]
39 and 40 are a flow of STEP (3) reproduction processing in step E10 of the flow of FIG. In FIG. 39, it is determined whether or not the event note is within the RANGE key range (step E39). If the event note is within the RANGE key range, it is determined whether or not the event channel and the guide part channel are the same. A determination is made (step E40). If the channels are the same, it is determined whether the event is a note-on event or a note-off event (step E41). If it is a note-on event or a note-off event, the channel of the event is changed to a navigation channel (step E42).
[0075]
Next, it is determined whether or not the event is a note-on event (step E43). If it is a note-on event, the event velocity value is changed to 1 (minimum value) (step E44). After changing the velocity value or when the event is not a note-on event in step E43, that is, a note-off event, the event is transferred to the MIDI output buffer (step E45). If the event is not a note event in step E41, the channel of the event is changed to the navigation channel (step E46), and the event is transferred to the MIDI output buffer (step E45). After transferring the event, the process returns to step E1 in the flow of FIG.
[0076]
If the event channel and the guide part channel are not the same in step E40, it is determined whether or not the event channel and the navigation channel are the same (step E47). If the channels are the same, the event channel is changed to the guide part channel (step E48). After changing the channel, or if the event channel and the guide part channel are not the same in step E47, that is, if the event channel is different from the guide part channel or the navigation channel, the event is transferred to the MIDI output buffer. (Step E49). After transferring the event, the process returns to step E1 in the flow of FIG.
[0077]
In step E39 of FIG. 39, if the event is not within the RANGE key range, it is determined in the flow of FIG. 40 whether or not the event note is outside the RANGE treble side key range, that is, the upper limit is exceeded (step E50). ). If the upper limit is exceeded, 1 is set to the UP over flag (step E51). When the upper limit is not exceeded, that is, when the lower limit is exceeded on the low sound range side, 1 is set in the DOWN over flag (step E52). After the UP over flag or the DOWN over flag is set to 1, it is determined whether or not the event channel and the guide part channel are the same (step E53). If the channels are the same, the event channel is changed to the navigation channel (step E54).
[0078]
If the event channel and the guide part channel are not the same in step E53, it is determined whether or not the event channel and the navigation channel are the same (step E55). If the channels are the same, the event channel is changed to the guide part channel (step E56). After the channel is changed in step E54 or step E56, or when the channel of the event is different from the channel of the guide part or the navigation channel in step E53 or step E55, the event is transferred to the MIDI output buffer (step E57). ). After transferring the event, the process returns to step E1 in the flow of FIG.
[0079]
FIG. 41 is a flowchart of the notice flashing process in step A7 of the main flow of FIG. In this flow, in order to blink the light emitting element of the electronic keyboard instrument 20, lighting data and extinguishing data are alternately transmitted at every blinking cycle time. That is, it is determined whether or not the blinking cycle time has elapsed (step F1), and if not, the process returns to the main flow. When the time has elapsed, the blinking flag is reversed (step F2). Then, it is determined whether or not the blink flag is 1 (step F3). If this flag is 1, note-on data is created with the notes in the notice flashing buffer (step F4). Further, the velocity value of the event is changed to 1, that is, the minimum value (step F5). Then, the event is transferred to the MIDI output buffer (step F6).
[0080]
If the blink flag is 0 in step F3, note-off data is created with the note in the notice blink buffer (step F7), and the event of the note-off data is transferred to the MIDI output buffer (step F6). After transferring the event, it is determined whether or not there is still note data in the notice flashing buffer (step F8). If there is still note data, the processes in steps F3 to F8 are repeated, and when there is no more note data to be processed in the notice flashing buffer, the process returns to the main flow.
[0081]
FIG. 42 is a MIDI processing flow in step A8 of the main flow of FIG. It is determined whether or not there is a new event input in the MIDI input buffer (step G1). If there is a new input, it is determined whether or not the event is note-on data (step G2). That is, it is determined whether or not the note-on data is pressed by the electronic keyboard instrument 20. If the input event is not note-on data, or if no new event is input in the MIDI input buffer, the process returns to the main flow. If the input event is note-on data, the note of the event is stored in the MIDInewON buffer (step G3). Then, the process returns to the main flow.
[0082]
As described above, according to the above embodiment, music data including a plurality of parts read from the FD 15 is input, an arbitrary part is designated as a part for exercise training, and the performance lesson designated in the electronic keyboard instrument 20 is performed. The exercise training part is assigned to the output channel corresponding to the input channel (navigation channel), and the exercise training part is transmitted from the output channel to the electronic keyboard instrument 20.
Therefore, when music data composed of a plurality of parts is input, it is possible to practice performance by using the navigation function for any part.
[0083]
In this case, performance training data for causing a light emitting element provided corresponding to each key of the electronic keyboard instrument 20 to be transmitted is transmitted from the output channel assigned to the performance training part.
Therefore, it is possible to practice a key to be pressed for an arbitrary part.
[0084]
Also, if a part for performance learning is specified in the input song data, if the specified part is different from the selected guide part, it is specified for performance learning. Assign a part to another output channel different from the output channel assigned to the guide part.
Therefore, even when a performance learning part is specified in the input music data, it is possible to assign the part to a channel that does not perform performance learning, that is, a sounding channel.
[0085]
In the above embodiment, the system configuration in which the electronic keyboard instrument 20 and the dedicated performance learning apparatus 10 are connected has been described.
