DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of a musical sound information display device according to the present invention will be described with reference to the drawings. FIG. 1 shows a system configuration of an electronic musical instrument to which the tone information display device according to the embodiment is applied. The display unit 1 is a liquid crystal display device including a liquid crystal display panel and a liquid crystal control / driver for driving the liquid crystal display panel, and is a display unit capable of displaying musical notes including staffs and other image information. The operation switch unit 2 inputs musical tone information including key signature, time signature, bar, pitch information, duration information, and the like of the music. The pitch detecting section 3 is composed of a keyboard and detects key press information for performance. Volume control unit 4
Controls the volume of sound emitted from the speaker 5 by adjusting the amplification factor of the amplifier 6 according to the operation.

The CPU 7 is control means for controlling the electronic musical instrument.
It is connected to the tone generator 10. ROM8 is a CPU
7, a program executed by the control unit 7, image information relating to musical notes to be displayed on the display unit 1, and other initial data in initialization. RAM9 is C
The input information input from the operation switch unit 2 and the pitch detection unit 3 by the PU 7 is temporarily stored. Tone generator 1
0 outputs waveform data in response to a tone generation instruction or a mute instruction from the CPU 7. The D / A converter 11 converts the waveform data output from the tone generator 10 into an analog signal, performs a filtering process, and supplies the analog signal to the amplifier 6.

Next, regarding the operation of the embodiment, a key switch (information input means) shown in FIG. 2 provided in the operation switch section 2 for inputting pitch information and pitch information, FIG.
The screen displayed on the display unit (display means) 1 shown in FIGS. 5 to 12 and the flowchart of the CPU 7 shown in FIGS. 13 to 20 will be described.

In FIG. 2, key switches a and b are switches for inputting pitch information, key switches c and d are switches for inputting pitch information, and key switches ENT are input pitch information and pitch input. This is a switch for determining the length information. When the power of the electronic musical instrument is turned on, the CPU 7
In the main flow of FIG. 13, a predetermined initialization process for clearing the register and the like of the RAM 9 (step S
Perform 1). After the initialization process, key signature setting,
The time setting and bar setting processing (step S2), the note setting processing (step S3), the display processing (step S4), and the tone reproduction processing (step S5) are repeatedly executed.

In the initialization process in step S1 of the main flow, as shown in FIG. 14, the register value dn of the RAM 9 for setting the pitch number (1 to 9) is set to the initial pitch di (step S6), and the pitch is set. Number (1-20)
Is set to the initial pitch gi (step S7), and 0 is stored in the register WDAT of the pitch accumulation data.
Is set (step S8), the bar register f is set to 0, and the pointer n is set to 0 (step S8).
9). In this case, the screen shown in FIG. That is, a region R1 for displaying the set bar, time signature, and staff, a region R2 for displaying pitches and accidentals of C3 to G4 together with the staff, notes from eighth notes to whole notes, notes and notes. Are displayed, and a region R3 is displayed which displays a tie symbol connecting, and rests from the eighth rest to all rests (hereinafter, these are collectively referred to as "signs"). Therefore, in this case, di is the pitch number 2 of the quarter note (the thick frame in FIG. 3), and gi is the pitch number 1 of C4 (the black circle in FIG. 3). Although not shown in the figure, in this initialization processing, a flag TF for displaying a tie symbol is reset to 0. When the initialization process ends, the process returns to the main flow.

Next, the operation of the CPU 7 in response to an input from the operation switch unit 2 will be described, taking as an example a case where a musical note of a two-bar song as shown in FIG. 4 is input. In the processing of key signature setting, time signature setting, and bar setting in step S2 of the main flow, the key signature is set in the register A of the RAM 9 according to the input from the operation switch unit 2 as shown in FIG. ), A beat is set in the register B (step S11), and a bar is set in the register C (step S12). When the key switch for key signature setting, time signature setting, and bar setting is operated, it is determined whether or not to proceed to note data (step S13). Is repeated. When each setting is confirmed, 1 is set to the bar register, and a note or rest pointer n to be input is set.
Is set to 1 (step S14). In the case of the music as shown in FIG. 4, CMj (c-adjustment length) is set in the register A, four beats are set in the register B, and two measures are set in the register C. Thereafter, the flow returns to the main flow.

Next, in the note setting in step S3 of the main flow shown in FIG. 4, as shown in FIG. 16, the key switch d (note length up) or the key switch c (note length down) of FIG. 2 is turned on. Is determined (step S
15). When the key switch d is turned on, dn is incremented (step S16), and the key switch c
Is turned on, dn is decremented (step S17). Then, it is determined whether or not the key switch ENT has been turned on (step S18). If the key switch ENT is not turned on, the process proceeds to step S15 to determine the operation of the key switch c or d. When the key switch ENT is turned on, the flow shifts to the flow of FIG.

In FIG. 17, it is determined whether or not dn determined by the key switch ENT is a tie symbol (step S19). The values set in the register dn are 1 to 9
And corresponds to the region R3 shown in FIG. dn =
1, 2, 3, and 4 have tone length data of 0.5, 1.0, 2,.
0 and 4.0 correspond, and note length data 0.5, 1.0, 2.0, and 4.0 correspond to dn = 6, 7, 8, and 9, but the tie symbol accompanies the note. Information and no duration data. Therefore, if it is not a tie symbol, the tone length data corresponding to dn is set in the register WDATn (step S20). Further, the current cumulative duration data WDA
WDATn is added to T to update WDAT (step S21).

For example, the first code in FIG. 4 designated by n = 1 is a quarter note, which is the same as the initial value shown in FIG. 3, so that the key switches d and c are also turned on in FIG. Therefore, the key switch ENT is turned on. As a result, WDATn = 1.0, WDAT =
0 (initial value) + 1.0 = 1.0. After updating the WDAT in step S21 of FIG. 17, it is determined whether the WDAT is smaller than the register B (= 4) which is the value of the beat set first (step S22). Now, W
Since DAT = 1.0, WDAT is smaller. In this case, it is determined whether the code designated by dn is a note or a rest (step S23). If it is a note, a pitch setting routine is executed (step S
24). Although not shown in the flowchart and the display screen, each time the key switch c or d is turned on, the position of the thick frame display in the region R3 of the display screen changes according to dn.

The pitch setting in step S24 is performed as shown in FIG.
As shown in FIG. 8, it is determined whether the key switch a (pitch up) or the key switch b (pitch down) in FIG. 2 has been turned on (step S25). Key switch a
Is turned on, gn is incremented (step S26), and when key switch b is turned on, gn is decremented (step S27). The pitch data set in the register DATAn by the ON operation of the previous key switch or as an initial value is stored in the register Dn.
The data is transferred to ATAn-1 (step S28). Next, it is determined whether or not the key switch ENT has been turned on (step S29). If the key switch ENT is not turned on, the process proceeds to step S25 to determine the operation of the key switch a or b. When the key switch ENT is turned on, the pitch data corresponding to the pitch number gn is set to DATAn.
(Step S30).

The initial value of the pitch data is C4, and n = 1
Since the pitch of the first note in FIG. 4 designated by F is F4, by turning on the key switch a five times, C
# 4, D4, D # 4, E4, DATAn-1 and DA
The pitch data of TAn changes in order, and the key switch ENT is turned on at the pitch of F4 to determine the pitch position to be displayed and the pitch data to be emitted. Although not shown in the flowchart and the display screen, each time the key switch a is turned on, the position of the black circle in the region R2 of the display screen changes according to gn.

Next, in FIG. 19, it is determined whether or not the pitch data of DATAn is a semitone (step S3).
1). Since the first note is not a semitone, the pitch data of DATAn is set in the register HDAT (step S).
32). Then, it is determined whether or not all the notes of the measure number C have been input (step S33). If not all the notes have been input, n is incremented to n = 2 (step S34), and the main flow is started. Return to

In the display processing in step S4 of the main flow, as shown in FIG. 20, key signature A is displayed (step S35), beat WDAT is displayed (step S36),
The bar f is displayed (step S37), the code corresponding to the pitch number dn is displayed in a thick frame (step S38), and the position corresponding to the pitch number gn is displayed as a black circle (step S3).
9). As a result, as shown in FIG. 5, the key signature CMjA, the bar 1, the beat 1.0, the length of the quarter note of the first note, and the pitch of F4 are displayed. After the display processing is completed, the process returns to the main flow.

In the tone reproduction process in step S5 of the main flow, the tone generation unit issues a sound generation instruction for the sound of "Fa" for the duration of a quarter note together with the waveform data of the sound of "F" at the pitch of F4. 10 given. Therefore, the user can hear the input note at the pitch and the pitch from the speaker.

Next, since the code in FIG. 4 specified by n = 2 is a tie symbol, the key switch d is turned on three times to shift the code in the bold frame to the right, and the key at the position of the tie symbol By turning on the switch ENT, the determined pitch number dn is determined to be a tie symbol in step S19 of FIG. In this case, it is determined whether the flag TF for displaying the tie symbol is 1 (step S4).
0). If TF is 0, TF is set to 1 (step S41), and if TF is 1, TF is reset to 0 (step S42). In this case, since the TF has been reset to 0 in the initialization processing, the TF is set to 1 in step S41. Thereafter, n is incremented to n = 3 (step S4).
3), and proceed to display processing. In the display processing of FIG. 20, it is detected that the flag TF is 1 in step S38, and a tie symbol corresponding to the determined pitch number dn is displayed in a thick frame. After the display processing of the tie symbol, the process returns to the main flow, but the musical sound reproduction processing in step S5 is processing for continuing the sounding of “F” based on the previous note, ie, the pitch of F4.

Thereafter, the process shifts to a note setting process in step S3. That is, in step S15 of FIG.
It is determined whether the key switch c or d has been turned on.
Since the code in FIG. 4 designated by n = 3 is an eighth note,
By turning on the key switch c four times to shift the sign of the bold frame display to the left and turning on the key switch ENT at the eighth note position, the determined pitch number dn is obtained in step S19 in FIG. It is determined that it is not a Thai symbol.
Then, in step S20, the tone length data 0.5 corresponding to dn is set in WDATn, and in step S21
Is updated from 1.0 to 1.5. In this case, WDAT (= 1.5) <B (= 4), and this code is not a rest, so that the processing shifts to the pitch setting routine of step S24 via steps S22 and S23. Note that the flag TF is 1, regardless of the ON operation of the key switch c, so that the thick frame display of the tie symbol is maintained as it is.

In the pitch setting processing of FIG. 18, since the pitch is the same as the first note, neither the key switches a and b are turned on, but the key switch ENT is turned on. Therefore, it is determined in step S25 that there is no change, and in step S28, the pitch data F of the data of DATAn is obtained.
4 is transferred to DATAn-1, and if it is determined in step S29 that the key switch ENT is on, the process proceeds to step S29.
In F30, the pitch data F4 corresponding to gn is D
Set to ATAn. Since the input pitch data is not a semitone, steps S31 to S3 in FIG.
The process proceeds to step S2, where the pitch data of DATAn is set in HDAT, and after step S33, n = 3 is incremented in step S34 to n = 4, and the process returns to the main flow.

In the display processing in step S4 of the main flow, as shown in FIG. 6, the beat changes from 1.0 to 1.5, the pitch position does not change, and the pitch in the thick frame display is a quarter note. To 8th notes and tie marks. Then, in the musical tone reproduction process, the pitch of F4 maintained by the tie symbol is not extinguished, and “F” is sounded for the duration of the eighth note. After the sound generation process, the process returns to the note setting process of the main flow.

In the pitch setting process of FIG. 16, the code of FIG. 4 designated by n = 4 is a quarter note, so that the key switch d is turned on once to obtain the pitch number dn in step S16. = 1 is incremented and dn = 2
When the key switch ENT is turned on, the pitch number d
n = 2 is determined. Further, since this code is a musical note and not a tie symbol, the pitch length data 1.0 corresponding to the pitch number dn = 2 is set to WDATn in step S20 in FIG.
Is set to WDAT in step S21.
It is updated from 5 to 2.5. In this case, WDAT (=
2.5) <B (= 4), and this code is not a rest, so that the processing shifts to the pitch setting routine of step S24 via steps S22 and S23.

In the pitch setting processing of FIG.
When the pitch data corresponding to gn is set to DATAn at 0, DA at step S31 in FIG.
When TAn is determined to be a semitone, the pitch values of DATAn-1 pitch data and DATAn pitch data are compared (step S44). Then, DATAn-1 <DA
If it is TAn, that is, if the current pitch specified by the key switch is higher than the previous pitch, D
Add the accidental # data to ATAn (step S
45). If DATAn-1> DATAn, that is, if the current pitch specified by the key switch is lower than the immediately preceding pitch, data of the accidental symbol ♭ is added to DATAn (step S46). DATAn-1
= DATAn, that is, if the current pitch is the same as the previous pitch, D with an accidental sign of # or ♭
The data of ATAn-1 is transferred to DATAn (step S47).

In the case of inputting a note with ♭ in FIG. 4 designated by n = 4, since the pitch of the preceding note is F4,
By turning on the key switch a, the pitch is changed from F4 to F # 4, G4, G # 4, A4, A # 4, B4, C5, C
It changes to # 5 and D5. Since the pitch of the note to be input is a half tone higher than D5, the key switch a is turned on. Then, in step S44 of FIG. 19, it is determined that DATAn-1 <DATAn. Therefore, D # 5 is set in DATAn in step S45. The pitches of D # 5 and E # 5 are the same,
In order to match the notes in FIG.
Is turned on, and the key switch b is turned on. As a result, in step S28 of FIG.
Since it is determined that -1 <DATAn, the process shifts to step S46 to add the accidental symbol ♭ to determine the pitch data E # 5. Thereafter, through steps S32 and S33 in FIG. 19, n = 4 is incremented to n = 5 in step S34, and the process returns to the main flow.

However, in this state, the tie symbol remains displayed in a bold frame. Therefore, in order to erase the thick frame display of the tie symbol, it is necessary to turn on the key switch d to turn on the key switch ENT in accordance with the thick frame display in accordance with the tie symbol. By this operation, step S in FIG.
In step S4, it is determined that the symbol is a Thai symbol.
The process proceeds to 0 to determine whether or not the flag TF is 1.
Now, since TF = 1, the process shifts to step S42 and T
Reset F to zero. In this case, the value is incremented from dn = 2 according to the operation of the key switch d,
The sign in the bold frame moves to the right from the currently determined quarter note. For this reason, after resetting the TF to 0 in step S42, the pitch number corresponding to the current pitch data of WDATn (quarter note data) is returned to dn = 2 (step S48).

Thereafter, in the display processing in the main flow, since TF = 0, the thick frame display of the tie symbol is deleted, and the determined quarter note length is maintained. As a result,
The display screen is the screen shown in FIG. 7, and the temporary symbol 表示 is displayed. Note that the key switch c or d is displayed on the display screen of FIG.
May be turned off when the icon is turned on. Next, in the tone reproduction process of the main flow, the sound of "half a semitone lower" with a pitch of E $ 5 is pronounced with the length of a quarter note and the sound of "flat" is pronounced.

Next, when the code of FIG. 4 designated by n = 5 is input, the key switch c is turned on and the key switch ENT is turned on in step S of FIG.
15, the processing shifts from step S19 to step S20 in FIG. 17 through the processing in steps S17 and S18, and the eighth note length data 0.5 is set in WDATn. Further, in step S21, WDAT is updated from 2.5 to 3.0. In this case, WDAT
Since (= 3.0) <B (= 4), and this code is not a rest, the processing shifts from step S23 to the pitch setting processing of step S24. In the pitch setting processing, the pitch data of C5 is set to DATAn through the processing of FIG. 18, and the steps S31, S32, and S3 of FIG.
After 3, n = 5 is incremented in step S <b> 34 to make n = 6, and the process proceeds to the display processing in step S <b> 4 of the main flow. As a result of the display processing, the display screen is shown in FIG.
It becomes as shown in. Step S5 of the main flow
In the musical tone reproduction process in the above, the voice of the pitch "C" at the pitch of C5 is generated with an eighth note pitch.

Next, when the code of FIG. 4 designated by n = 6 is inputted, the key switch d is turned on and the key switch ENT is turned on in step S of FIG.
15. After the processing of step S17 and step S18, the process proceeds from step S19 of FIG. 17 to step S20, where the note length data 1.0 of the quarter note is set in WDATn. Further, in step S21, WDAT is updated from 3.0 to 4.0. In this case, WDAT =
Since B = 4 and this code is not a rest, the processing shifts from step S23 to the pitch setting processing of step S24.

In the pitch setting processing, when the key switch b is turned on, the pitch is shifted from C5 to the lower pitch. However, since the note with n = 6 has #, n = 6 is selected by the key switch b. After setting the pitch to A4, which is a semitone lower than the pitch of note 6, the key switch a is turned on. Therefore, FIG.
After step S31 of step 9, the process moves from step S44 to step S45, and the pitch data of A # 4 is set in DATAn. Then, step S32, step S33
In step S34, n = 6 is incremented to n = 7, and the process proceeds to the display process in step S4 of the main flow. As a result of the display processing, the display screen is as shown in FIG. Further, in the tone reproduction process in step S5 of the main flow, the voice of the pitch “A semitone higher” of the pitch of A # 4 is generated with a quarter note pitch,
The voice of "sharp" is pronounced.

Next, when the code of FIG. 4 designated by n = 7 is input, the key switch d is turned on and the key switch ENT is turned on in step S of FIG.
15. After the processing of step S17 and step S18, the process proceeds from step S19 of FIG. 17 to step S20, and the half note duration data 2.0 is set in WDATn. Further, in step S21, WDAT is updated from 4.0 to 6.0. In this case, WDAT
Since (= 6.0)> B (= 4), step S22
Then, the process shifts to step S49 to increment bar f = 1 to f = 2. Then, it is determined whether or not the measure f is equal to or less than the measure C of the initial value (step S50). In this case, since the bar f (= 2) is equal to or less than the bar C (= 2) of the initial value, the WDA set in step S20 is set.
The tone length data 2.0 of Tn is set in WDAT as beat data of the second bar (step S51). And
The process proceeds to step S23, and since this code is not a rest, the process proceeds from step S23 to the pitch setting process of step S24.

In the pitch processing, when the key switch b is turned on, the pitch is shifted from A # 4 to the lower pitch, and the key switch ENT is turned on. Therefore, after step S31 in FIG. 19, steps S44 to S4
Then, the pitch data of G # 4 is set in DATAn. In this case, it will move to the lower pitch,
When DATAn is a semitone, the accidental symbol ♭ is added.
Then, after step S32 and step S33, in step S34, n = 7 is incremented and n = 8
Then, the flow shifts to the display processing in step S4 of the main flow. As a result of the display processing, the display screen is as shown in FIG. Also, in the tone reproduction process in step S5 of the main flow, the sound of the “half semitone lower” of the pitch of G ♭ 4
A "flat" voice is pronounced at the same time as the note length.

Next, when the code of FIG. 4 designated by n = 8 is inputted, the key switch d is turned on and the key switch ENT is turned on.
15. After the processing of step S17 and step S18, the process proceeds from step S19 of FIG. 17 to step S20, and the note length data 1.0 of quarter rest is set in WDATn. Further, in step S21, WDAT is updated from 2.0 to 3.0. In this case, WDAT
(= 3.0) <B (= 4), and after step S22, this code is determined to be a rest in step S23. Therefore, the pitch setting process in step S24 is not performed, and step S52 is performed. Then, n = 8 is incremented to n = 9, and the flow shifts to the display processing in step S4 of the main flow. As a result of the display processing, the display screen is shown in FIG.
It becomes as shown in. In this case, since it is a rest, the tone reproduction process in step S5 of the main flow is not performed.

Next, when the code of FIG. 4 designated by n = 9 is input, the key switch d is turned on and the key switch ENT is turned on in step S of FIG.
15. After the processing of step S17 and step S18, the process proceeds from step S19 of FIG. 17 to step S20, where the note length data 1.0 of the quarter note is set in WDATn. Further, in step S21, WDAT is updated from 3.0 to 4.0. In this case, WDAT =
Since B = 4 and this code is not a rest, the processing shifts from step S23 to the pitch setting processing of step S24.

In the pitch setting processing, by turning on the key switch b, the pitch moves from G # 4, which is the pitch of the preceding note, to the lower pitch, and the key switch ENT is turned on. Therefore, after step S31 in FIG. 19, the process proceeds to step S32, and the pitch data of C4 is set in DATAn. Then, in step S33, it is determined that all codes have been input, and step S4 of the main flow is executed.
Shifts to the display processing of. As a result of the display processing, the display screen is as shown in FIG. In the tone reproduction process in step S5 of the main flow, the sound of the pitch "C" at the pitch of C4 is produced with a quarter note length.

As described above, according to the above-described embodiment, when the pitch information is input in response to the operation of the key switch and the pitch position and the accidental symbol on the staff are displayed, the input sound is used. In the case where the high information includes accidentals, a sharp accidental symbol is displayed when operated in a high pitch direction, and a flat accidental symbol is displayed when operated in a low pitch direction. Therefore, a correct accidental symbol can be displayed by a simple operation.

FIG. 21 shows an example of an operation switch unit according to another embodiment. The rotary encoder 21 is a means for setting a sound length and a pitch. When the rotation operation is performed clockwise, the sound length is long and the pitch is increased, and when the rotation operation is performed counterclockwise, the pitch is short and the pitch is reduced. Key switch 22
Is a switch for designating information input from the rotary encoder 21 as a sound length, and the LED 23 is an indicator indicating that the sound length is designated. The key switch 24 is a switch for designating information input from the rotary encoder 21 as a pitch, and the LED 25 is an indicator indicating that the pitch is designated. In this case, a flag process for identifying whether the input mode of the rotary encoder 21 is the pitch input mode or the pitch input mode is necessary, but other processes are described in FIGS. Since the flowchart is the same as that of the CPU 7 shown in FIG. In another embodiment, the information input from the rotary encoder 21 may be automatically switched to the pitch or the pitch in accordance with the ON operation of the key switch ENT. In this case, the key switches 22 and 24
Becomes unnecessary.
