In addition, the switch 21 of the cursor movement key part 2-1 is CR
The switch 22 moves the cursor displayed on T4 upward, the switch 23 moves the cursor downward, and the switch 24 moves the cursor downward. moves the cursor to the left. Further, the designation switch 25 instructs to input the information currently surrounded by the cursor into a predetermined register. The control circuit 31 also detects this operation of the cursor movement key part 2-1.

The control circuit 31 also controls a register ACOSA which will be described later.
CI, ADRI, AI) R2, AI) Various judgments are made using the control register 32 including ELM, etc., and the final information is stored in the memory 33. Note that this memory 33 can be divided into a plurality of areas, and the control circuit 31 can specify the address of each area, and can write and read data to and from the memory 33.

Further, the control circuit 31 controls the mixdown section 34 to
It sends and receives data and control signals, and performs the mixdown function. In other words, for example, after performance information for each measure is input for each part and stored in multiple memory areas in the memory 33, the mixdown section reads out each piece of information, and the timing ↑N included in it is read out. Information (
By adjusting the tone length information), it functions to input performance information for one measure of mixed down into one memory area.

In addition, 35 in the figure is a display driver, and CI

In addition, this control circuit 62 sequentially transmits information indicating scales or rests to the musical tone generating circuit 65 from the personal computer 1 and converts the information indicating a musical scale or rest into an acoustic signal by the musical tone generating circuit 9 to produce sound. be done.

Next, details of the mixdown section 34 will be explained with reference to FIG.

After the counter (also abbreviated as CNT) 41 is cleared by the clear signal CLL output by the control circuit 31 at the start of the mixdown process, the counter (also abbreviated as CNT) is similarly controlled (
b) Execute counting operation by inputting the +1 signal outputted from path 31. The count output is sent as time data to the A input terminal of the matching circuit section 42, the subtractor 4308 input terminal, and the latch (
(also abbreviated as LASTT) 44 L1 input terminals.

The latch data of the latch 44 is applied to the B input terminal of the subtracter 43 via the L output terminal.

The subtracter 43 subtracts the input data of the B input terminal ＼ from the input data of the input terminal −＼ for kneading, outputs the time data of the difference from the 0 output terminal, and stores it in the specified channel (area) in the memory 33. ) as one of the synthetic data −
Let's put v.

The time data from the two channels to be mixed down in the RAM S are read out and applied to the input terminal of the adder 45. Further, the 13 input terminal or the C input terminal of the adder 45 is provided with time data latched by a latch (also abbreviated as NEXTj) 46 for one of the two channels, or a latch (NEXTZ) for the other channel. (also abbreviated as)4
The time data 7 is latched is inputted respectively. In addition,
A signal NEXT1/, which switches which latch 46 or 47 is used to perform the addition operation, is applied from the control circuit 31. Then, the adder 45 adds the input data of the input terminal -\ to the input data of the B input terminal \ or the input data of the C input terminal \, and outputs the resulting data as new time data to the D output, respectively. The signal is output from the terminal or the E output terminal, and the latch 46 or latch 47 is latched. Note that the latches 46 and 47 are connected to the control circuit 31, respectively.
The latch operation is performed when each of the signals LAI and LA2 is output. Furthermore, at the start of the mixdown process, the clear signal CLR output from the control circuit 31 is
latches 46 and 47 are also cleared along with counter 41.

Each latch data of the latches 46 and 47 is stored in the matching circuit section 42.

Matching or mismatching of the input data at the input terminal \\ is detected, and a match signal E2 is outputted and sent to the control circuit 31\\.

Next, a method of inputting performance information according to this embodiment will be explained below. FIG. 4 is a diagram showing the display state in CR and T4 when the mode for inputting performance information is set by operating the keyboard 2. In addition to controls, marks 402 such as notes and rests are displayed respectively. . Additionally, a cursor 403 is displayed.

Also shown is a line 404 that distinguishes the upper stage from the lower stage.

The cursor 403 has a size that matches the enclosure of the mark 4()2, and the cursor movement key is partially 2-2.
By operating each of the switches 21 to 24 of 1, it is possible to move it upward, rightward, downward, and leftward.

FIG. 5 is a flowchart showing the processing operation of the control circuit 31 in accordance with the operation of the cursor movement key part 2-1.
First, in step S, it is judged whether the designated switch 25 is turned on or not.

When this determination is made, the process proceeds to step St, where it is determined whether any of the cursor movement switches 21 to 24 has been operated. If the decision is NO,
Return to step S again. For example, switch 24
When the cursor 403 is operated, the process proceeds to step Ss, in which the control circuit 31 moves the cursor 403 to the left.
is controlled, and the cursor 403 on CI'(T4 moves to the left. In this way, the cursor 40'3 is moved to the switch 2.
By operating 1 to 24, the robot moves to the position shown in FIG. 6, 4. When the designation switch 25 is operated in the state shown in FIG. 6, a YES determination is made in step Sl, and the process proceeds to step S. In step S4, it is judged whether the cursor 403 is above the line 404, and since it is now below the line 404,
A NO determination is made, and the process proceeds to step S. In step S, the tone length information (or special symbol, etc.) is judged from the current position of the cursor 403 and is imprinted in the θ) register ACO in the control register 32. In this case, σ
) The note length information is a code indicating a half note.

Then, following step S, the process proceeds to step S1, where it is judged whether or not the designation switch 25 is pressed. If the determination is NO, the process proceeds to step S. Now, operate the switch 21 to move the cursor 403
When \ is moved upward, the result becomes as shown in Fig. 6(B) through the process of step S.

When the designation switch 25 is operated in this state, the register AC is
The content of O is partially modified and a code indicating information about a half note and # is input. Also, the display inside the cursor 4 ( ) 3 changes as shown in FIG. 6 (C). Then, by operating the switches 21 and 22, the cursor 403 is moved to the position shown in FIG. At this time, the display within the cursor 403 remains as shown in FIG. , pitch information corresponding to the current cursor position, that is, the position of the half note in this case, is generated in the control circuit 31 and input to the register AC1 in the control register 32.

Then, in step S, the pitch information of the note is stored at the first address of a predetermined area of the memory 33, and the timing information (length information) is stored at the next address. Note that the specific data storage state will be described later. And now, the display in the cursor 403 of FIG. 6 (Q is S-4O
It will be fixed on the X, and when the cursor 403 is moved from now on, the display inside it will not overlap.

In step S, it is determined whether the sum of note length information among the performance contents in a predetermined area of the memory 330 exceeds the note length of one measure. Now, in this song, the length of a whole note (expressed as CO as explained later) is one measure long, so
It is compared with the length of this whole note, and it is determined that it is "small", so the process returns to step S. If this step S.

If it is determined that they are equal, it means that the input of performance information for one bar is completed, and the process moves on to inputting the next bar. Then, in step S, if it is determined that it is "dog", it means that the performance information has been input exceeding the note length of one measure, and in the next step S, C11(, T
Display the error on the screen in step 4.

In this way, by inputting performance information for each note, performance information for one measure is stored in the memory 33, and by manipulating it, performance information for one song is input. Ru. Now, in this embodiment, as shown in FIG.
It changes depending on the information indicating F). Timing information specified by note length or note length is encoded as shown in FIG. The code shown in FIG. 8 is now expressed in hexadecimal.

Therefore, for example, following the notes shown in Figure 6 (CJ K),
If performance information is input as shown in FIG. 9 (Jun), data shown in FIG. 9 (2) is stored in a predetermined area of the memory 33.

That is, among the data shown in Fig. 9 (■), the first bar 1 gai) 'c3'' instructs to start sounding the C# scale note of the third octave.The next 1 gai) '6
0' indicates the length of a half note. next byte' c
H'' instructs to start muting the scale note that has started to be sounded.

The next pi)'(10' indicates that the tone length is zero, and the scale note specified by the next byte is processed at the same time as the above scale note C# is silenced.Then, the next byte is processed. The scale note is one note of B in the second octave.And,
Furthermore, the next byte '30'' indicates the length of the quarter note.The next byte 'HA' instructs to mute the scale note B,
Furthermore, since the next byte is '00', at the same time as the muting, the start of sound generation of the scale note A of the second octave indicated by the next byte is instructed. Then, in the next byte, it is understood that the note length corresponds to a quarter note. next pie)
'AA' instructs to mute the scale note A, and '00' in the upper pie indicates that the generation of all scale tones in one bar has been completed.

In this way, the performance information for one bar shown in FIG. 9 is encoded and stored in the memory 33. Then, in the same manner, the performance information of the following measures is sequentially inputted, and the performance information of the entire song is stored in the memory 33. Thereafter, by performing a predetermined operation on the keyboard 2, this performance information is transferred to the electronic musical instrument 6 and stored in the memory 64. Therefore, in the electronic musical instrument 6, by providing the musical tone generation circuit 65 with performance information sequentially read out from the memory 64, it is possible to execute the performance.

Next, the mixdown function of this embodiment will be explained. As mentioned above, the mixdown section is divided into 34 parts,
That is, FIG. 9 (■) and FIG.
The song is stored in two areas (channel 1, channel 2), the song is mixed down, and performance information corresponding to FIG. 9 (5) is obtained in another area (channel 3). In addition,
Depending on the song, the parts may be divided into a bass part and a treble part, or a bass part, a middle part, and a treble part, and various methods can be used.

FIG. 10 is a flowchart of the control circuit 31 for explaining this mixdown function.

First, when a mixdown is commanded by operating the keyboard 2, steps M, , M, of the flowchart are executed.
, M, , M4 are executed, and the output of the clear signal causes the counter (CNT) 41 and latch (NEXTI
) 46, Latch (N13XT2) 47, Latch (L
ASTT) 44 are reset together.

By the next steps MH and Ma, the control register 32
The start address is preset in the address register ADRI for channel x (CHl) and the address register ADt (2) for channel 2 (C:N2).In other words, the data shown in FIG. is stored in the channel 1 area, and the data shown in FIG. 9 ψ) is stored in the channel 2 area. Therefore, the start address of each area (for example, address 0 of each area) is now specified by register ADI(, 1 and A I) R2.

Then, in the next step M, the area of the memory 33 where the data obtained by mixing down both channel 1 and channel 2 data is stored, is now channel 3.
(CH3), the start address of this channel 3 (for example, address 0 of that area) is set to the control register 3.
It is stored in the register ADRM in 2.

Proceed to the next step, Old. Now, the coincidence circuit section 42 judges whether the data of the latch 46 and the count output of the counter 4 match or not, but since both are "0", a coincidence signal E1 of '1' level is generated. and control circuit 31
To give fangs. Therefore, between the I control circuits, the process of step M is performed to reduce JTl.

"The data "o" of the latch 44 is subtracted from the data "0".
0" is stored in the first address of CH3.

Next IC, the count output "0" of the counter 41 is set in the latch 44 and held as the previous data (step M
,. ). Then, in step M1, the register A
The DRM is incremented by 1 to become the next address (for example, address 1), and the contents of the first address of CI-11, in this case, "c3", are read and written to the first address of CI-I3 (
Step M,,).

Next, the specified address of CHI is +1 up to the next address (1
address) in step M+s, and the next step MI4
Then, the control circuit 31 reads the time data '60' at address 1 of CH1 and sends it to the A input terminal of the adding section 45. Then, it is added to the time data '00' of the latch 46 to the B input terminal, and the resulting time data '60' is latched into the latch 46 again. Then, ADRI is increased by +1,
Address 2 is set (step M□), and then ADRM is incremented by 1 to become address 2 (step M, 6). Then, the process returns to step M8.

Next, in step M8, the time data of the latch 46 is set to 16.

Therefore, a determination of NO is made, and then step Ml,
Proceed to.

In this step M 1 y, the same process as in step M above is executed for CH2 of the memory 33, and the matching circuit section 42 uses the count output "V0" of the counter 41.
0' and the latch data '00' of the latch 47 is determined and a match signal E2 of 1'' is output, and the control circuit 31-
\give. By kneading, the control circuit 31'''Q&-1, steps M, , K proceed.Here, the following steps M,

That is, step M1. Now, add subtractor 4 to address CH302.
The result data 'oo' of step M is filled in and entered. Then, '00' is latched in the latch 44 again.

And step M. , M□ write data 'E2' from address CI-1200 shown in σ() in FIG. 9 to addresses 3 of CI-1 and CI-3. Next, AI)R2 is incremented by 1 to become the 1st address (step M□), and in step M0, it is added to the time data ``30'' of the 1st address of CH2,
As a result, data ""30' is latched into latch 47. Then, in step M14, N'L+, ADR2 is set to address 2, ADRM is assigned address 4, and then step Ml? Return to

In step M17, the data '00' of the counter 41 is
A discrepancy between the data 130' and the data 130' of Latte 47 is detected,
A coincidence signal E2 of '0'' is output, and the process proceeds to step 1%La, where it is judged whether or not the data of CHI and CH2 have completed one measure.Since the data is not at the end now, the process proceeds to step M!? , the control circuit 31 outputs a +1 signal to the counter 41 and sets the count output to '01#.

Then, the process returns to step M.

In this step M, it is determined whether the output 101' of the counter 41 and the output '60' of the lunch 46 do not match, and in step M1. The process proceeds to Step M11 as well, where it is determined that there is no mismatch tf17, Step M, 6, Step My? The counter 41 is incremented by 1 and becomes '02', and step.

Return to M.

Hereinafter, the contents of the counter 41 are the data 13 of the latch 47.
