Description

[Detailed Description of the Invention] This older brother 1υJi, HJ (relates to a music display device that automatically displays 5.IIf? based on the supplied sound collection 11 sound information and measure signal, 4'a' G This invention relates to a method for arranging sounds 1 to 1, which makes it possible to display precise measure intervals.

In recent years, V/1 has become popular with music Ir1, which displays the process of playing on a piano, electronic organ, etc.
(The display device is open. By the way, this 111
(When manufacturing a Raku llu display device, the most difficult point is the display of bar lines. In other words, the bar line display generally occurs at a constant Ji'dJtJJ.)
) signal, but the date and time of the occurrence of this bar signal
The timing of f mink and the timing of the player's key operations on a piano or the like do not normally match in all cases, and there is often a slight deviation. As a result, if the bar line is faithfully displayed in accordance with the elapsed time and f mink when the bar signal is generated, a situation may arise where the display of a note or rest and the bar 1 display overlap.

Therefore, this invention eliminates such inconveniences and makes it possible to display appropriate measures f# light. Display device ζL
This method provides a method for processing musical sound alarms when the musical sound information is ashed, and when the difference between the musical sound information ashing timing and the occurrence of measure doubling is less than a constant value, the above-mentioned music The musical tone information is processed by assuming that the change timing of the 1f information is the same as the occurrence timing of the measure (i-), ;.

An embodiment of the present invention will be described below with reference to one drawing.

7. This is a block diagram showing the +1 configuration, and the ease d shown in this diagram is
The II display device jPt automatically displays the performance process on the piano 1 as a musical score.

That is, the piano 1 is provided with a key switch for detecting a key operation corresponding to each key (!I), and the output of each key switch is supplied to the #i'j instrument intern ace 2, respectively. On the other hand, parameter setting setting 3 is for setting the tone (C major v4, A short note, etc.), tempo (for example, quarter note length), and time signature (% meter only). The key data, tempo data, and meter data corresponding to the selected tone, tempo, and meter are respectively supplied to the note selection processing circuit 4, and the tempo data and meter data are supplied to the bar signal generator 5. The signal generator 5 detects the length of one measure based on the tempo data and time signature data supplied from the parameter setting device 3, and generates a short period of time (for example, 5 m5ec) at a period equal to the detected length of one measure.
It generates bar No. 14 P, which is at H'' level, and supplies it to the musical instrument interface 2. Also, this device 5 synchronizes bar No. 3 to No. P by 1Tr1, and generates a weak ?A signal tone for a short period of time. This V (signal tone) is to notify the player of piano 1 of the break between measures.

The musical instrument interface 2 sends the outputs of each key/f of the piano 1 and the measure signal P at a fixed period (for example, 4 m
sec), the on/off state of each key switch and the level of the measure signal P are detected, and changes in the on/off state of the key or the level of the measure signal P (
When an event (hereinafter referred to as an event) occurs, an event block 1B shown in FIG. 2 Cf) is created and output to PiS 2 a during event block processing. Here, from the event block, as shown in the figure, from a minimum of 4 bytes to f11
The first and second bytes contain the evening time, which indicates the time from the previous event occurrence time to the current event occurrence time.
r master data TMD is inserted, the third byte contains the indicator IND shown in Figure 2 (O), and the fourth byte contains the key code of the key that has changed. KO is entered by ν.In this case, ll is provided roughly according to the number of events from the block consisting of the indicator HD and key code KO.For example, when a certain key is turned off and another key is turned on at the same time, 2 if
Two block A IIBs are provided corresponding to the change in the key.For example, if a certain key is turned off and the measure signal P rises to H level at the same time, the key change and the measure I3 from two blocks in response to a change in signal P.
will be removed. The key code for E is not used for later processing (it may be written). Also, from this event block, Indicator ND
If B indicates key on/off from that block, "0" and 0' are set to the 1st and 0th bits, respectively, and if the key is on, the 7th bit) (MSB )
If the key is off, NO'' is written in the seventh pit.゛In addition, if the block EJ3 indicates a change in the measure signal P, the first and Oth bits are each set to "1".
, 0'' is inserted in layer 1.The most significant pit (MSB) of the key code that arrives is always 0'.

That is, in this embodiment, the key code is substantially represented by seven pits.

FIG. 3 is a timing chart showing an example of key operation, in which keys a to 0 of piano l are played "N2" at the timings shown in FIG.
If so, event blocks E-1 to $-6 shown in FIG. 4 are created at times t1 to t6, respectively, and output from the event block processing circuit 2aΔ. In addition, the hth
-1 timer data T>x:o[1ooJ from the event block in li\J means that the time from the previous event occurrence time to time t1-1 becomes 100 pulses of the clock pulse that is the basis of time 1F measurement. It shows that they are equivalent. Similarly, timer data TMDj185J of event block 1B-2 is set at time 1. This shows that the time between and time t2 corresponds to 185 clock pulses. The same applies to other timer data TMD.

When the bar signal P is generated during the key operation time, the event block processing circuit 2a processes the event block as appropriate so that the bar line of the display image mi does not overlap with the musical note, and outputs the corrected event block as a. This is what is output and will be explained in detail below.

First, the basic concept of the data processing method in the event block processing circuit 2a will be described.

° First, as shown in key b shown in FIG.
20m5ec) before the time 70□, and the predetermined time ε2 (for example, 6
0m5ec) at time t8. ．． If the key b is turned off after the key b is turned off at time t, it is assumed that the key b is turned off at time t and then turned on again at time t4. That is, at time t4, B is input into the vent block E-4 from the block indicating that key b is off, and B is input from the block indicating that key b is on. In this case, as shown in m5V(a), notes corresponding to key b are displayed before and after the bar entry. In addition, in the case of ζ,
It is necessary to tie the two divided notes when displaying them, so a flag indicating that they should be tied is added to E from the added key-on block A II B and key-on block. . Next, if key O shown in FIG. 3 is turned on within time C1 and turned off after time t8□, key 0 is turned on at time t4
It is treated as if it was turned on. Zunawachi,
Hang 1 from the event block to block 1 indicating that key 0 is on, and -2 from the event block.
The block EE of key C on is invalidated. In this case, the musical note corresponding to key C is displayed after the bar note as shown in FIG. 5(b). Next, if the key d shown in Figure 3) is turned on within time 11 and turned off within time s□, it is processed as if the on time is t2 and the off time is t. . That is, block E 11E indicating key d OFF is placed in event block 1B-4. In this case, as shown in FIG. 5(c), the key d
The corresponding note will be displayed before the bar.

Next, if the measure signal P is not generated within the key-on time, like key a or θ shown in figure C11, -1
:: hB Do not perform unreliable correction processing. next,
Although the Er'S3 figure is not shown, a certain key is pressed at time t.
If it is turned on before ``as'' and turned off within time 6□, the OFF time is the same as key d.

It is treated as if . Then, the event block for which the above-described correction processing has been completed is output as a from the corrected event block.

The above is the basic idea of data processing in the event block processing circuit 2a. Next, the specific data processing process in this event block processing circuit 2a will be explained in the sixth section.
This will be explained with reference to FIGS.

Figure 6 shows the event block processing amount j! 32a is a diagram showing storage areas of a memory provided in the instrument interface 2, and in this diagram, SPE is a temporary storage area where event blocks supplied from the musical instrument interface 2 are first stored, Flu-0 to EK-1. Each group has a temporary storage area of 8.
The event block in PR1 is the event area where the speed changes. In this event area 11E, event blocks are placed in the eaves, as well as the famous 7 lags and blocks. tl) Figure 7 is a diagram showing where each fG+ data is stored in the event area EE.As shown in this diagram, the area EE contains the ef flag (1 byte) and the data TMD from the event block. (2 bytes), number of blocks BLC (1
Byte) is included in fJ1, and area ~Fj, □
respectively, the indicator I N D of Flock E EB.

Key code KO is M (inserted, Effrag, K
The flag is set to 4. In this case, area IC,,E2
. . . corresponds to B from each block from the event block. In addition, the number of blocks ELO is
Area red, ~Ii, is the number of blocks EI3 in which '<IA is buried in □. Also, within this area EE)1[ are timer data TMD and indicator IJD.

Effrag, key code KO1. Note that the T) lag is embedded in the 7th bit (MSB) of the key code KO.

Next, 'pi! In Figure 6, KTL is the on-state Q! of each key of Via/'1. The key of i is registered in the key on table of 96 bytes, and this key on table is full KT.
Area TcO” “II 7 of L is 88 of Piano 1.
It supports multiple keys. ,,Note that areas "88 to 5" are not used in this embodiment.

Each area F of this key-on table KTL. , I:1・
Each of ... consists of 32 bits (4 bytes), the 0th to 7th bits (q) are unused areas, and the 8th to 23rd bits (2 bytes) indicate the key-on time. On-time data TON is written, and the D flag is set to flat, 1. The 26th to 30th bits must be unused on the ship, and a 1-bit mark M indicating whether the key is on or off is set to 1 (4J). is 1' when the key is on,
In the case of key-off, "o" is depressed and swollen.The 1' mark in FIG. 6 is a timer register in which the elapsed time from the time point P of measure 1C occurs is written.

Next, each of the above-mentioned 72 goes, K1 D, and 'I' will be explained.

is written as 1 (1), and then "1" or "2" is written when the event block containing the measure clear block EE is supplied.

T-Niji (When displayed, this is a flag that indicates whether or not to connect the same number with a tie, and the next data is omitted including '@1.

O: When it cannot be tied with a tie 1: When it is tied with a tie As described above, four types of flags are used in this example, but the internal work of these flags, Klp is a flag for correction processing from the event block, and only the T flag is a flag for display processing to be described later. Therefore, only this T flag is output to the next stage circuit.

Next, referring to the flowcharts shown in Figures 81\, 1 and 8ir 9, and taking the key operation case shown in Figure 3 as a second, the data processing process that goes to event block Kisaragi 1 same way 28 will be explained. Theory 1.1. In addition, as a premise for the following explanation, it is assumed that all keys other than key mill 0 are in the off state room 1, and that the event area KE-0-1cE-

The time of one measure corresponds to the data [zoooJ]. Also, true.

The figure shows the contents of the key-on table KTL and the timer register TM11.4 vent areas IDE-0 to FF-G after the processing at times t1 to t6 is completed.

First, at time t1, from the event block -],
When the event block 1B-1 is supplied, this event block 1B-1 is checked in step s4 shown in FIG. 8, and the process proceeds to step SP2. At step sP, -1 is written from the event block into the temporary storage area 5PIC (FIG. 6). Next, proceeding to step sp, the timer data TMD of event block 1B-1 is ``100J''.
is added to the content of timer register TMD “1700J, and this addition η-result “1oooJ” is added to timer register TMR.
1tt is entered (see Figure 1).Next, proceeding to step sp4, it is checked whether there is a key in the currently ON state?, !1.In other words, the key-on table KT Each area E of L.-"87 mark M is checked. In this case, there is no turnkey key,
Therefore, the process advances to step SP5 shown in figure fA9.

In step S P, -Special unique area S],'

The block II (in this case, r2J) is placed in the area Eo of the event area BE-0 as the block 19Bro. At this point, the EF flag, EF flag, and K flag in the event area ER-Q are all "o" (see Figure 10).
,.

Proceeding to the next step sp, event block 1B
It is checked whether there is a block B (block E[] whose MSII of indicator ND is "1") among blocks indicating key-on within -1. In this case, both of the two blocks J3B indicate key-off, so the process advances to step s'Pi. At step SP8, keys a and b, which were turned on at time t, are given negative values in the key-on table KTI. That is, key a
As the area (Ko-Ea,) of the key-on table KTL corresponding to and b, respectively,
(see Figure 10 1 (J.

At this time, both the D flag and the on-time data TON in the area corresponding to the key a%h are FOJ.

Next, proceeding to step S P, the event block E
It is checked whether there is a block IBB in -1 indicating key-off. In this case, block EE indicating key-off is not included, and therefore steps sp,
Proceed to o. In step 5Plo, event block 1
B-1 shows the bar line (i.e. block IB where the first bit of IND is 11")
I3) is checked. In this case, the block 113B indicating the bar 1 door is not included, so the process proceeds to step Sl). In step SP, □, output processing of a from the correction event block to the next stage is performed. This output process will be explained later, but at this point, the correction event that can be output to the next stage;
There is no a from the block, so step S P,
Return to

The above is the process performed in the event block processing circuit 2a when -1 is supplied from the event block at time t1. Next, when -2 is supplied from the event block at time t2, step SF,
This event block ll3-2 is frozen in the temporary storage area SPE, and then the contents of the timer register TMR are changed to [1985J
(see Figure 10), and then proceed to step S dog. In this case, the key-on table KTL contains keys a,

Therefore, proceed to step sp, 5. Here, ToN>
11 means that the on-time t1 of key a is earlier than the upper time shown in FIG. 3. In other words, it means that the above-described correction is not necessary for the on-time of key a. Next, in step sp, 5, a flag [801] is written in the area where the block A IIB indicating key n on in the event area EE-0 is written (see FIG. 10).

Next step sp1. If you proceed to the event area EF (in this case, Il!E-0) where the K flag was populated
It is determined from each block in 1' (1 is cut off) whether or not all the correction processing of II has been completed. At this point, the flag for key b is in the "0" state), so the process advances to step sp.In step SP1□, the correction process for the key-on time of key b registered in the key-on table K T II is performed. It is checked whether everything has been completed. In this case, the process 11 of key b has not been completed, and therefore the process returns to step sp, 3. Step S"
At +3, the D flag of key b is checked, and then the process proceeds to step S P,5 via step S P "+30" is 8

Correction processing! Steps 11 and 11 have all been completed, so the process advances to step SP8. In step sp, , "80" is added to the event area EE-0's flag (see the self-Xlo diagram).

Next, proceeding to step S Psr, at this point h, the key θ5, which is registered in the key-on table FFTL, is
b key on I+? The processing for all four clocks has been completed, so the process advances to step SR.

In step SP, -2 is taken from the event block into the event area Je E -1, and then in step SP6, the number of flocks ILLC (this j combination is "2").
) is written in the event area in E-1,
Then, the process advances to step SPI. In this case, step s
The determination result at p is [y v: s J, so the process advances to step SP8, and the key C%d is registered in the key-on-table KTL (see FIG. 10).

Then, the process proceeds to step sp, , via step S P, , S P,o. Step L) In PIH, the EF flags of event areas EE-0 to KID-15, which are currently 114 times smaller than the event block, can be checked in the order in which the event blocks are 114 times smaller.

And if FZIG is 180, that event area is 1! Output processing 1 of event block 1B in j Also, in the case of l'-ooJ, or in the case of "01" and the content of the timer register TMR is smaller than the constant time sense 2, the check of the e-flag ends at that point.

Furthermore, when output processing is performed, the event area Ell is cleared.

Therefore, in this case, the e-flag of event KE-0 is checked without landing. And this efrag is “

That is, for keys whose on-time data Tou is greater than time 8□, 14 rlJ is included as the D flag, and for keys whose on-time data Tou is not "0" and whose time is smaller than time 6□, "rlJ" is included as the D flag. 2" is included (f
J) l See figure 0). Note that for keys whose on-time data TON is "0", the D flag ν, i-input is not performed (the state of D7 lag "0" is maintained), and then the process proceeds to step SP. , each on-time data TON of the key-on table KTL can all be cleared. The reason for performing this process is that the currently registered key on-time data TON will not be referenced from now on, and on the other hand, if the key operation time is long, the on-time data TON may become more than 2 bytes. This is because there is. Next, proceed to step SPA, and "01" is the e-flag and 111 to °C-1 vent area KF-3! then step SP2g
When the process proceeds to step sp, the timer register T M n is cleared, and the process proceeds to step sp, . In this case, the EF flag of event area TI:E-1 is still in the rOJ state, so the output processing of the corrected event block Ila is not performed in steps sp, .

Next, when event block l1l-5 is supplied at time t5, steps S P2, sp, sp4, sp
After 1□ is executed the next time, the process advances to step sp, .

In step S P, 3, - first, enter the key-on table'

. Note that the first process described above means that it is assumed that the off time of key d is the generation time t4 of measure signal P, and the next process is to consider that the off time of key d is the generation time t4 of bar signal P. This means that B is invalidated from the key-off block of d.

Next, step sp3. Proceed to event area EE
From the key-on block of key d in -1, "80" is re-set to the flag in 13. The sweetness of this treatment is as follows. That is, if the OFF time of the key d is after the stamp t82 (FIG. 3), as in the case of the key 0, it is processed as if the ON stamp of the key d was the time t4. However, if the off time of key d is within time 82 as in the case of tj > 3 in the figure, if two consecutive processes are performed, the on time of key d (between 11η in the on state) becomes rOJ. I will die. Therefore, the on time of key d is time 61 BiJ,
In addition, when the off time is within the time 42, no correction processing is performed on the on time Ij, and processing is performed as if it were the same as the previous on time. Next, proceeding to step SP3゜,
From the key-off block of key d in event block EE-3, "80" is written into the flag of E. Next, proceed to step SP3□, and the event area "/rirE
It is determined from all key-off blocks within -5 whether or not the correction process for B has been completed. In this case, the processing of key 8 has not been completed, and therefore the process returns to step 5P33. In step 5P33, it is determined what the D flag of the key θ is. In this case, it is rOJ, so proceed to step sp, 5.

In step sp, , the event area IIE-3
From the key-on block of keys to e inside, go to the flag "8" of B.

Then, 80 codes are input from the key-off block of key θ in event area ICE-4 to the flag of B.Then, proceed to step SP3. In this case, the judgment result of step sP3;'c is "yxsJ, proceed to step Sr2□." In the two consecutive processes, if the D flag is [ll, step S p to step S p,
Proceed to step 8. The processing at step SP3° is exactly the same as the processing at steps sp and 4.

Next, in step SP2□, steps sp35,
It is determined whether the correction processing of each block E IIE in the event area III Knee 3 and El-4 in which "80" is written 1 is completed in sp, . In this case, the correction process for E has been completed from all blocks in the event area EE-A, so proceed to Stella 7'5P23 and set the event area EE-4)1 flag to "soJ

Go to 3. In step sp p,, first, key-on table K
It is determined whether the D flag of key b registered in the TL is rQJ. In this case, the judgment result is “NOJ is acceptable.
Therefore, go to step sP3□'tWtr. 'r-January at step sp.? lIr h”i 31!: is “Y II: S J −Cab,!j, Step 5
Proceed to p4o. Step SP. Then, it is determined whether the D flag of key b is rlJ or not.

In this case, the D flag of key b is "1", so the process advances to step 5P4X. In STETSUNO SP4゜, from the key-off block EE indicating key b off and the key-on block indicating key b on, B is jjl (¥iJ is included in the event area Bj K -3 which takes B from the i-th measure Hiro block. (See Figure 10).The meaning of this chore i is that the key is turned on before time ts□ (Figure 3).
If the key is turned off after time ta2, the same key is once turned off at the same timing as the measure signal P, and processed as if it were turned on at the same time. Next, when proceeding to step SP4□, the above-mentioned step sp
, , ``1'' and ``80'' are written in the EF flag and the K flag of the key-on and ``2''-off block queries EB, respectively, of the key b written in the event area u:ie-3.

Next, proceeding to step 5p16, the event area 11j
It is determined from each block in Ti-3 whether all the correction processing of B has been completed or not. In this case, the flag in block B indicating the nodule forest is rOJ, and therefore the process proceeds to step sp. In addition, in this embodiment, the flag of the bar block E EB never becomes "80". Each data in the event area KE-3 including the bar song proc query EB is output processed after the time ε2 has elapsed since the bar sickle block IBB was supplied, as described above.

In step SP1□, it is determined whether processing of all keys registered in the key-on table KTL has been completed. In this case, the processing of key 0 has not been completed, and therefore the process returns to step SP. Thereafter, a determination is made to step SP and 3% S regarding key 0, and then step s
p. Proceed to. Step sp. Then, it is determined whether the D flag of key C is "1" or not. In this case, the D flag of key O is "2", so the process advances to step 5P43. Step SPa"!' is the event area I!j
From the block indicating key C on in II-1, B is in the event area 'EE-3 which includes the measure block IEB,

Step SP2 via □! When he goes there, "80" is written to the e-flag in event area EE-5. When the process advances to the next step 5P24, the registration of key b in the key-on table KTL is deleted. Then, the process proceeds to step sp, 1 via the STETSUNO 5PIo. In this case, event area]]:Bon-1, E: 1! j -2, 1 discharge -4, T!
Each efrag of 2F-5 is t'tJrooJ,
Therefore, the output power is low. Shoda, Koga) h method 7'
Regarding the event conciliar KE-3 including the open IBB, the contents of the timer register Tλ4R at this point are greater than the time 5□, and therefore each data in the event area 11iE-3 can also be output. As a result, in step sp, the event IJ 7
Ev: Each data in -1 to Ell-5 is input as the next event block Ila in the order of event occurrence.

The details of the processing in the event block processing circuit 2a have been described above. Next, the note selection chore circuit 1 circuit 4 and subsequent circuits shown in FIG. 1 will be explained.

The note selection processing circuit 4 performs event block processing “I circuit 2
Based on the correction event block IEa/ supplied from a, the on/off state of each key of the piano 1 is detected, and the timing of the occurrence of the measure (i number P) is detected, and based on this detection result, the Create the slot tag 1 cock sn shown and output it to the symbol assembly circuit 6 (Z). below,
To explain further, for example, as shown in FIG. l-Raku! If
If f is played completely by Piano 1, the extension (not shown in Figure 1): K! The costume device 1 can display this musical drama almost in its original form. The note selection section JJjN4 creates data for displaying this music iV1ν in the form of slot blocks SB for each slot S1, 82, . . . shown in FIG. FIG. 11 shows the basic configuration of this slot block SB, and the first byte includes slot widths (not shown in FIG. 12) such as slot width S Lt S L4... ...) is written, and the 2nd to 4th bytes each contain T Y P E data,
114 length data and key codes are included. in this case,
The slot width is determined by the length of the note (rest), 9
For the slot width of slot SI, a note length code (described later) corresponding to the longer note G4 shown in FIG. Also, the second ~
The block SBB consisting of the fourth byte is composed of musical notes, rests or bars, and slots S1, S2, etc.

As for the length data, the lower 6 bits contain a note length code of 4 (inclusive), which corresponds to the length of the toy note or rest.

In this example, whole notes (whole rests), half notes (half rests), quarter notes (quarter notes), etc.
The note length codes LNI, LN2, and L correspond to the valley lengths of

That is, what is represented by the block SEB is the result of the beginning of the tie. In the case of a note (for example, a note in slot s6), the upper two bits of the recognition data are "1, 0"; In the case of a note in slot S-, the upper two bits of the long irises index are 0.1''.Next, as a key code shown in the AYII diagram, if the block S'BB does not contain a note, its upper two bits are 0.1''. The key code of the note is) 1! 1 is included, and "0" is included in iAF when the body slope represents the measure axis.廿, slot block SE is small 1i'i, 1
．． , l (for example, slot S shown in FIG.
1, $7, and S10), the slot block SB) created in response to S10 has a slot width of a certain number of data S H
It becomes O.

In this case, the length data and key code of the slot block SB are not used in subsequent processing. Therefore, each created slot block SB is written in the order in which it should be displayed.

Next, the symbol assembly processing circuit 6 generates a display block [1B (FIG. 14) for displaying notes, rests, bar axes, or tie symbols) corresponding to the slot block SB supplied from the note selection processing circuit 4. Create and perform note kk indication processing ftF
11 power is applied to circuit 7. Here, the display block HB is jl
r As shown in 141J, Jα low 4 bar (from
i'j was created and its third. The slot width of the supplied slot block SE is written in the byte, and the X coordinate, the X coordinate, and the UDS code are written in the second to fourth bytes, respectively. Furthermore, the block 11BB consisting of the second to fourth bars is the block SUB of the slot block BB.
For example, slot block SB
If there is a 21 fixed 7' lock 813B inside, the display block H created corresponding to this slot block SB.
B contains block HBB of 2 (1'il).If a time mark indicating the start or end of a tie is inserted in the length data of the slot block SB, the tie is displayed. The final block HB E is added. In this sushi block HB, what is the x1 seat mark? Slots S1 and S2 in Figure 4112...
Data indicating the position in the X direction of a note, rest, measure break, or tie symbol (for example, the distance ffft from the left edge of slot S8, S (...) is included. is a constant value that corresponds to the normal sound shrine, body dip, measure win, and tie symbol, respectively. Also, as the X coordinate, the position in the Y direction within slots S1, S2, etc. +

The data indicating this is inserted. The position Fl in the Y direction is determined by the key code in the block SEE of the slot block SE in the case of a musical note or a tie mark, and is a fixed position in the case of an o, a rest, and a measure fat. Also, as a UDS code, ai types of notes or rests (quarter notes, eighth rests, etc.)'! ! Take-bar axis, Thai notation-
UDS code corresponding to 8-1. be included. That is, in the memory 8 shown in FIG. 1, all musical notes, rest patterns, tie symbol patterns corresponding to the start and end of ties, and bars Ik+In are stored in advance in the form of vectors. For example, a quarter note is stored by the start and end points of the vectors Vr, Vi, etc. shown in Figure 15, and a half note is stored by the vectors V, , , V shown in the same figure.
, □..., the starting point and ending point of
The tie symbols roughly indicating the start of a tie are stored in vectors ■3I to ■, and the tie symbols indicating the end of a tie are stored in the coordinates of the starting and ending points of vectors ■34 to '36. ", 〔Remembered. A UDS code is defined corresponding to each of these patterns. Therefore, when the block SBB of the slot block SH contains a note or a rest, the symbol assembly processing circuit 6 determines the UDs code based on the length data in the program block 5BII, and the determined UDS:
1-code into the display block HB, and if the slot block SB represents the measure axis (TYPEi data is 13), write the UDS code of the measure axis into the display block HB, and then write the UDS code of the measure axis into the display block HB. If the block SBB has a tie symbol, write the UDS code of the tie a self number to the display block HBT.

The musical note display processing circuit 7 displays the X, Y coordinates in the display block HB supplied from the symbol assembly processing circuit 6 (display). ) and outputs it to the display device 9 together with the UDS code. That is, for example, when displaying a certain 1fW not shown in FIG.
, i(;q(x'-1)), and this coordinate (x
/-1) and display block H corresponding to slot S1
From the X coordinate in E, output 1121% 4 shiba of note G4 'J9.

Next, the right end of slot SI (slot s

q, and from this coordinate (X'-3) and the X coordinate in the display block HB corresponding to slot S3, the X' coordinate of the bar is calculated by 39.

Thereafter, the X' coordinates of each note, rest, and bar line are determined in the same manner. Further, the Y'l mark of each note etc. is determined from the Y' coordinate of Gozo and the Y coordinate within each display block. Then, the note display processing circuit 6 calculates x′ of each note, etc.
Output the Y' coordinate along with the UDS code to the display +tt9.

Display +i, t 9 is C! RT (brown bamboo) display device and! This device is configured with a 1ilJ fi11 circuit, and displays five patterns on the 0IIT screen, and also outputs patterns such as a sound scoop from the memory 8 based on the supplied UDS code, and displays each of the read patterns. The coordinates are converted based on the x' and Y' coordinates mentioned above, and notes, rests, bar lines, and ties are displayed on the CR1 screen.
Display the issues in the order of progression of the song. In addition, direct interpolation is performed between the tie symbol corresponding to the start point of the tie and the tie symbol corresponding to the end point of the tie.

Note that the circuit shown in FIG. 1 is normally constructed using a microcomputer. Furthermore, in the embodiment described above, O
RT release stud 16? However, in addition to this screen display and JIJ, or in place of the screen display, the musical score may be printed by a printer.

According to the present invention, the time difference between the change timing of the musical tone information and the generation timing of the measure signal is calculated, and when this time difference is less than a predetermined value, the change timing of the musical tone information corresponds to the measure. Since the musical tone information is processed assuming that it is at the same time as the signal generation timing, there is an advantage that bar 1 can be displayed at the most appropriate position when displaying the musical score.
