Converts the tone signal from the sound source from digital to analog,
A predetermined signal processing such as amplification is performed to generate and mute sound.

The music information data stored in the ROM 4 is configured for each music as shown in FIG. That is,
16-byte song title character string data, 2-byte song data address, 2-byte fingering data address, 2-byte musical score image data address, 1-byte tempo data, 1-byte beat data, 1-byte key data Have been. Each data is specified by an address offset from the head address with “0” as the head address. The head address of the first music piece is represented by “INFO ADR TOP” in the control program.

The musical score image data is image data for one music piece, and as shown in FIG.
It is designated by the score number “7”. The display device 6 displays two levels of musical score images. FIG. 5 shows the format of music data, which is composed of a note number, a step time, and a gate time for each musical score data in the order of address SNG ADR. What is a note number?
This is data of numbers “0” to “127” indicating the pitch. However, data with a note number of "-1" is NOP data and is not sounded. Therefore, when there is a rest at the beginning of the song as in the example of FIG. 4, the note number is "-1".
Becomes The step time is data indicating the time until the next tone data. The gate time is data indicating a sound generation time.

FIG. 6 shows the format of fingering data.
In the order of address FING ADR, note number, fingering number, elapsed fingering number, X position, Y
The position is configured. The fingering number is the number of operation fingering image data corresponding to fingering indicating the start of operation of an arbitrary key on the keyboard 1. The elapsed fingering number is the number of elapsed fingering image data corresponding to the fingering indicating the progress up to the start of the operation of the next key. In FIG. 7, “1” to “5” are fingering images of the operation fingering image data, and “0”, “6”, and “7” are fingering images of the elapsed fingering image data. The data of the X position and the Y position in FIG. 6 are the data of the position of the cursor indicating the score to be performed according to the progress of the music in the score image displayed on the screen of the display device 6.

FIG. 8 is a main flow of a control program executed by the CPU 1. First, the stopped data is set in the register STATUS indicating the current state, and "0 (first song number)" is set in the register SNG NUM indicating the song number of the currently loaded song. (Step A1). Next, music loading processing is performed (step A2). Thereafter, a loop process of repeating a switch scan (step A3), a time process (step A4), and a display process (step A5) is executed.

FIG. 9 is a flowchart of music loading processing in step A2 of the main flow. In this processing, a register INFO AD indicating the head address of the music to be played is provided.
The value of INFO ADR TOP (start address of the first music) +25 (bytes) × SNG NUM (music number) is set to R (step B1). As shown in FIG. 3, each song is specified by data of every 25 bytes,
The music number to be played is specified by adding the value obtained by multiplying the music number by 25 bytes to the head address. Next, tempo data is set in the timer 7 (step B2). Then, the process returns to the main flow.

FIG. 10 is a flowchart of the switch scan process in step A3 of the main flow. It is determined whether or not the contents of STATUS indicate that the music is stopped (step C).
1) If the music is stopped, it is determined whether or not the start switch is turned on (step C2). When this switch is turned on, the register LTM representing the previous timer value is added to the register PTM representing the current timer value.
Is set, "0" is set in a register ETM indicating the elapsed time, "0" is set in a register LETM indicating the elapsed time from the beginning of the score of one stage, and the score update flag UPDF is set to "1". (Step C
3).

Next, "0" is set to a register USN indicating the upper score of the displayed two-stage score, and "1" is set to a register LSN indicating the lower score of the score. "0FF (H)" is set in the register LTCK indicating the number of ticks of the displayed score, and the upper (upper) is set in the register CL indicating which of the displayed two scores has the cursor at present. Set (step C4).

Next, INFO AD is added to SNG ADR.
Data of an address obtained by adding 16 bytes to the value of R is set (step C5). That is, as is apparent from FIG.
Set to ADR. Next, to FING ADR, IN
Data of an address obtained by adding 18 bytes to the value of the FO ADR is set (step C6). That is, as is clear from FIG. 3, the fingering data address of the music to be played is set. Next, "0" is set to a register ONTIME representing the On wait time (step C7).
Then, the contents of STATUS are set during the music performance (step C8), and the process returns to the main flow.

If the start switch is not turned on in step C2, it is determined whether or not the music selection switch is turned on (step C9). When this switch is turned on, a music selection process is executed (step C1).
0). Then, the new song number of the selected song is given as SNG NU
It is set to M (step C11). Next, SNGNU
The music loading processing shown in FIG. 9 is executed according to the content of M (step C12). Then, the process returns to the main flow.

If it is determined in step C1 that the content of STATUS is not music stop, it is determined whether or not the stop switch is turned on (step C13). When this switch is turned on, the content of STATUS is set to the state in which music is stopped (step C14), and the process returns to the main flow.

FIG. 11 is a flowchart of a music selection process in step C10 of the switch scan process of FIG.
In this process, a song selection screen is displayed (step D)
1). As shown in FIG. 12, a song number and a song name are displayed on the song selection screen. Next, the pointer n is set to "1 (first song)" (step D2). Next, the music title specified by the pointer n is highlighted (step D3).
Thus, if n is set to "1",
The first song title "Kirakiraboshi" is highlighted.

Next, it is determined whether or not the UP switch is turned on (step D4), and when it is turned on, n is decremented (step D5). Then, it is determined whether or not n has become “0” (step D6). If n is not "0", the process shifts to step D3 to highlight the song name of the song number n changed by the UP switch.
In step D6, the decremented n is “0”
, Change n to “1” (step D).
7). Then, control goes to a step D3. That is, when the UP switch is turned on in a state where the title of the first song number is highlighted, the switch operation is invalidated and the display is not changed.

If it is determined in step D4 that the UP switch has not been turned on, it is determined whether the DOWN switch has been turned on (step D8). When this switch is turned on, n is incremented (step D).
9). Then, it is determined whether or not n exceeds MAX (the last music number) (step D10). If n is equal to or less than MAX, the process shifts to step D3 to highlight the song name of the song number of n changed by the DOWN switch. In step D10, the incremented n
Is greater than MAX, n is changed to MAX (step D11). Then, control goes to a step D3. That is, when the DOWN switch is turned on in a state where the title of the last song number is highlighted, the switch operation is invalidated and the display is not changed.

In steps D4 and D8,
If neither the UP switch nor the DOWN switch is turned on, it is determined whether or not the OK switch is turned on (step D12). When this switch is turned on, the new song number is set to the number of n (step D13),
Clear the display of the song selection screen of FIG. 12 (step D1
4) Return to the flow of FIG. If the OK switch has not been turned on, it is determined whether or not the Cancel switch has been turned on (step D15). When this switch is turned on, the display of the music selection screen of FIG. 12 is cleared (step D14), and the flow returns to the flow of FIG.

In the flow of FIG. 10, as described above, the new song number selected in the song selection process is SNG N
Set to UM and the song is loaded. The loaded music image is displayed on the screen of the display device 6 by the display processing in step A5 of the main flow. Then, the image of the song displayed on the screen changes with the progress of the song, that is, with time.

FIG. 13 and FIG. 14 show the flow of the time processing in step A4 of the main flow, and FIG.
It is a screen such as fingering displayed according to the progress of a song. FIG.
In step 3, it is determined whether or not the contents of the STATUS indicate that a musical piece is being played (step E1). If the musical piece is not being played, this flow is immediately terminated, and the flow proceeds to the main flow display process. If the content of STATUS is playing a song,
Step E2 is performed. In this process, the ETM
The value obtained by subtracting the LTM data from the TM data is added. That is, the elapsed time up to the previous time is updated to the elapsed time up to the present. In addition, LETM writes L
The value obtained by subtracting the TM data is added. That is, the elapsed time from the beginning of the musical score one stage up to the previous time is updated to the elapsed time up to the present. Also, PTM data is set in the LTM. That is, the previous timer value is changed to the current timer value.

Next, it is determined whether or not the elapsed time of LETM has exceeded the time of LTCK (step E3). That is, it is determined whether or not the elapsed time of one musical score exceeds the tick time of the musical score and the musical score ends. If the elapsed time of LETM exceeds the time of LTCK, it is determined whether or not the data of CL is Upper (step E4). That is, in FIG. 15, the cursor 11 is currently displayed on the upper row (Upper) 12 or on the lower row (Low).
er) 13 is determined. CL data is Upp
If it is “er”, the data of CL is changed to “Lower” (step E5). If the CL data is Lower, the CL data is changed to Upper (step E6).

After the CL data is changed, "0 (no music score update)" is set in the UPDF and the LET is set.
M is set to "0 (the head of the changed stage)" (step E7). That is, in this case, the performance time of only one of the two displayed musical scores has ended.
Therefore, the score to be displayed is not updated, and the level of the score for displaying the cursor is changed.

After step E7 or when the elapsed time of LETM does not exceed the time of LTCK in step E3, it is determined whether or not UPDF is "0" (step E8). If UPDF is "0",
In this state, the performance time of one musical score out of the displayed two musical scores has ended, and the performance of the second musical score has now started. In this case, when the performance of half of the score of the second stage has passed, it is necessary to update the score of the stage which has already been completed. For this reason, the LETM time is one of the LTCK times.
/ 2 is determined (step E9).

If it exceeds, the CL data is
It is determined whether or not r (step E10). Upp
er, the LSN is incremented by "2" (step E11).
N is incremented by “2” (step E1)
2). For example, if the currently displayed upper and lower musical scores are the musical score of the musical score number “2” and the musical score of the musical score number “3” in FIG. 4, and the cursor is located at the lower stage, the musical score of the musical score number “2” is displayed. The score is changed to the score of score "4".
If the upper and lower musical scores currently displayed are the musical score of the musical score number “4” and the musical score of the musical score number “3” and the cursor is located at the upper stage, the musical score of the musical score number “3” is changed to the musical score number “ 5 ”. The screen in FIG. 15 is in this state. After updating the upper or lower score,
"1 (the score is updated)" is set in the PDF (step E13).

At step E13, "1" is set in the UPDF.
Is set, or in step E8, the
If is already “1”, or if the elapsed time of LETM does not exceed １ ／ of the time of LTCK in step E9, the process shifts to step E14 in FIG. It is determined whether or not there is. When waiting for On, the elapsed time of ETM is O
It is determined whether or not the NTIME On waiting time has been reached (step E15). If the On waiting time has not been reached, this flow is immediately terminated and the flow returns to the main flow.

When the On waiting time is reached, SNG A
It is determined whether or not the DR note number is “−1 (rest)” (step E16). SNG ADR is "-1"
In the case of, the data of the step time of SNG ADR + 1 is set in ONTIME (step E1).
7) The SNG ADR is incremented by "3" and the process proceeds to the next musical score (step E18). Then, this flow ends and the process returns to the main flow. For example, in the example of the score shown in FIG. 4, since the first score is all rests, the step time of all rests is set to ONTIME, and the note number of the next score is set to SNG ADR.

When the flow shifts from the main flow to this flow again, since the next musical score is also a full rest, step E16
Then, the process goes to steps E17 and E18. In this case, the note number (C4) of the musical score in the second row in FIG. 4 is set in SNG ADR. Therefore, when the flow shifts from the main flow to this flow again, step E
At S16, it is determined that the note number of the SNG ADR is not "-1". As a result, a NoteOn process, that is, a sound generation process for the sound source 8 is executed (step E1).
9). Next, a register OFFT representing the Off wait time
The gate time, which is the data of SNGADR + 2, is set in IME (step E20).

Next, it is determined whether or not the note number of FING ADR is "-1" (step E21).
If it is “−1”, the next address FING AD
The R data is the tick time of the musical score at the stage where the cursor is currently located. Therefore, the ticking time of FING ADR is set to LTCK (step E22). Then, FING ADR is incremented by "5", and the note number of the next fingering data is designated (step E23).

After step E23 or step E21
If the note number of the FING ADR is not "-1" in step, fingering On processing is performed (step E24).
In this process, of the fingerings “1” to “5” shown in FIG. 7, the operation fingering image data corresponding to the fingering indicating the start of the key operation of the NoteOn process is selected from the ROM 4 and read out. It is given to the display device 6 to be displayed. On the screen of FIG. 15, fingering indicating the start of the operation of the musical score specified by the cursor 11 is displayed. Next, cursor movement processing is performed (step E25), and “0” is set in ETM, and the contents of STATUS are set to Off wait (step E26). Then, this flow ends and the process returns to the main flow.

If it is determined in step E14 that the content of STATUS is not waiting for On, it is determined whether or not the content is waiting for Off (step E27). If it is not waiting for Off, the flow is immediately terminated and the process returns to the main flow. If waiting for Off, it is determined whether or not the elapsed time of ETM has reached the time of OFFTIME (step E28). If the Off waiting time has not been reached, this flow is immediately terminated and the process returns to the main flow.
When the Off waiting time has been reached, a Note Off process, that is, a mute process for the sound source 8 is performed (step E2).
9).

Next, a value obtained by subtracting the gate time of SNG ADR + 2 from the step time of SNG ADR + 1 is set in ONTIME (step E30). In other words, the ONTI time is defined as the time from the sound-off processing in the NoteOff processing to the start of the sounding of the next musical tone as the On wait time.
Set to ME. Then, the SNG ADR is incremented by “3”, and the note number of the next score is changed to SNG.
ADR is set (step E31).

Next, fingering off processing is performed (step E).
32). In this processing, “0”, “6”,
Of the fingering of “7”, the elapsed fingering image data corresponding to the fingering indicating the progress until the start of the operation of the key pressed next to the NoteOff process is selected from the ROM 4, read out, and displayed. 6 to be displayed. Next, FINGA
DR is incremented by "5", and the operation fingering image data for starting operation of the next key to be pressed is set in FING ADR (step E33). Then, set “0” to ETM and change the contents of STATUS to O.
The wait state is set to n (step E34). Then, this flow ends and the process returns to the main flow.

As described above, the fingering display device according to the above-described embodiment includes a display means (display device 6) for displaying an image of fingering that guides the performance of a song, and an arbitrary operator (keyboard) according to the score of the song. A plurality of types of operation fingering image data corresponding to fingering indicating the start of operation of one arbitrary key) and a plurality of types of fingering indicating progress until reaching the start of operation of the next operator (key) Storage means (R) for storing elapsed fingering image data
