Other processing (step 190) is performed,
A series of processing consisting of steps 110 to 190 is repeatedly executed.
Run. [0039]2. INC / DEC switch processing The INC switch 38 and the DEC switch 40 in FIG.
For changing the input / output state TBL (csx, csy)
It is. Referring to FIG. 9, in step 111, IN
Whether the C switch 38 and the DEC switch 40 are turned on
Check for no. Either of these switches 38 and 40
If it is not turned on, the process returns to the main processing (FIG. 8). one
On the other hand, if one of the switches 38 and 40 is on,
Next, at step 112, the performance mode JOB and the cursor y
Inspect the target CSY. Performance mode other than stop (JOBH
0) and the cursor specification is not in track mode
If (CSYH5), the process returns to the main process (FIG. 8). This
This allows input / output channels during playback or recording
Changes are prohibited. If the performance mode is stopped (JOB = 0),
Either the cursor is in track mode (CSY
= 5), the process proceeds to step 113. Step 113
Now, the cursor y coordinate CSY and the input / output information register TBL
Check the contents of (csx, csy). If the cursor is
Lock mode (CSY = 5) and cursor x coordinate
The mode of the track specified by CSX is the recording mode (T
If BL (csx, 5) = 2), go to step 115
Otherwise, go to step 114. Step 1
In 14, whether the switch turned on is 38 or 40
Of the input / output information register TBL (csx, csy) according to
After incrementing or decrementing the volume,
Return to the processing (FIG. 8). In step 114, TBL (csx,
csy) 0-7 when CSY = 1 or 3 0-15 when CSY = 2 or 4 0-2 when CSY = 5 Increase or decrease in the range. For example, TBL (csx, 5) = 2
Set to 0 when incremented. As a result of the inspection in step 113, CS
When Y = 5 and TBL (csx, 5) = 2,
When switch 38 or 40 is ON, track number CSX
Change the track mode of the track from the record mode
If you want to change to another mode,
In switches 115 to 126, the switch 38 or 40 is turned off.
Key-off processing for a key that is currently depressed
Perform That is, at step 115, the control variable i is

When the count value becomes 0, the recording timer interrupt (Fig. 24) is executed.
I do. Here, the elapsed time LNSAM is replaced by the old LNSAM +
(100H-old RECCNT) = 0 + (256-13)
= 243 and RECCNT is cleared. * Key event data K_B Processing This data K_B Processing is K_A Is executed in the same way as sand
That is, data K_B Is read (step 602) and written
The old data 0 of the time register RECCNT is changed to the old write time
Save to register OLDRCCNT and register RECCN
Set a new RECTIMER value (write time) 1 to T
(Steps 631, 632), and event K_Three To K_B
Time interval LEN = LNSAM + (RECCNT−
(OLDRCNT) = 243 + (1-0) = 244 and
K_B To K_Four Remaining time until LNEST = old LNRE
ST-LEN = 250-244 = 6 is calculated and the elapsed time
LNSAM cleared (steps 633-635)
After that, the time interval data LEN = 244 and the input key event
Data K_B To the new sequence data area
(Steps 636, 642). * Key event data K_Four Processing This data K_Four Is performed on the data K_Three Line in the same way as
Be done. That is, the write time RECCNT is changed to the old REC.
CNT + (LNEST-LNSAM = 1 + (6-0)
Update to = 7, clear LNSAM, and time interval
K as LEN_B To K_Four Remaining time up to LNEST
= 6 and set the time interval LEN = 6 to the new data area
(Steps 402 to 405)
To the key event (FIG. 16 or FIG. 17)
Data K_Four (Step 221)
223). Further, returning to step 205 in FIG.
The time proceeds to the time interval data processing (FIG. 18), and the reproduction timer
PLAYTIMER and remaining time register LNRES
Set 10 as time interval data to T
(Steps 263, 264). As described above, in this embodiment, the reproduction
When recording performance sounds, the timing information
Because the calculation is based on data,
When using the recording timer value at the time of recording as the
Such multiplexing does not increase the playing time. [0094] The present invention is limited to the above embodiment.
It is not specified, and applied with various modifications as follows
can do. For example, 1. In the above, it is stored in the sequencer memory 18
Although the case where the sequence data is one song has been described,
It may be several songs. 2. I used keypress information as sequence data,
Other event information, such as a change, can also be used. 3. I / O key code buffers IKBUF, OKC
BUF is prepared for each track, but it is prepared for each terminal or channel.
You may prepare for every channel etc. 4. The clock may be supplied externally. 5. You can have any number of tracks. 6. In the above embodiment, the display is omitted for simplification.
However, if necessary, a means for displaying necessary information should be provided.
Is also good. 7. Edit, delete, copy, modify, etc.
It is easy to add a cut function.
