Depending on the processing, the tempo count data TCNT is "0" to "3".
Repeated every time the tempo clock signal TCLK is generated
And then step forward. Explanation of solo style play The following is the formation and production of additional sounds in solo style play.
Let's talk about raw material, but before that,
Reaffirmed about items closely related to ray mode operation
I'll do it. Key-on routine for each mode MDiKON and key-off for each mode
Routine MDiKOF is the step of the key release event routine above.
It is read out and executed in the pages 230 and 234.
If the Leplay flag SSP is "1" and the melody is played
When any key is pressed and released on keyboard 10
And read according to the mode data MD (= i)
To be executed. Further, in such a case, the processing of the above step 224
By reason, the 0th key for the 0th tone signal forming channel
-The code KC (0) and the 0th volume data VOL (0) are the above
It is set for each key pressed, and in the solo style play mode
Indicates that the melody performance on keyboard 10 is given priority to
It The chord change routine for each mode MDiCHG is the key release event
What is read and executed in step 218 of the routine
, The auto accompaniment is working, and the solo style play
Gus SSP is "1" and on keyboard 10 for playing chords
When any key is pressed, the mode data MD
Reading is executed according to (= i). Also, where it takes
In step 212, the root representing the designated chord
The sound data ROOT and the type data TYPE are for the chord.
It is set according to the key press. The clock routine MDiCLK for each mode is
The read routine is executed in step 252
Stuff, with automatic rhythm running and solo style
When the play flag SSP is "1", the tempo clock
It is executed every time the signal TCLK (corresponding to 32nd note) is generated. When the solo style play flag SSP is "1"
For the 0th to 6th tone signal forming channels,
The 0th to 6th tone color data TC (0) to TC (6) of
According to the processing of steps 146, 148, 166 and 168 of the in-program.
Mode of solo style play (corresponding to the rhythm type
It is set every time). Also, steps 150-1
By the processing of 56,170 to 176, the mode type is rhythm dependent.
If the current mode or the accompaniment-dependent mode,
The dynamic rhythm and the automatic accompaniment operating state are forcibly set.
It Specifically, the above steps 150 to 156 and 170 to 176 are performed.
By reason, the rhythm run flag RUN is set to “−1”,
Alternatively, the accompaniment flag ABC is set to "1". However, each
Rhythm type corresponding to solo style play mode, No. 0
~ 6th tone color data TC (0) ~ TC (6), rhythm ramp
About specific data setting of RUN and accompaniment flag ABC
Will be described later. Next, let's move on to the explanation of the actual solo style play mode.
There are many types of solo style
Rays are prepared, but in the present embodiment, the present application
Solo style play mode (3,1
(3,14 Solo style play mode) only
It 3rd solo style play mode 3rd solo style play mode (MD = 3) is melody key
1st to 3rd with the same pitch as the melody as long as the key is being pressed
If additional sounds are started and stopped in sequence at predetermined intervals,
However, the volume is alternately changed, and the rhythm type is likened to
For example, it is the one designated for the "Mandolin band".
At the same time, the automatic rhythm is set to the standby state (RUN = -1)
To be done. Also, in this mode, the 0th to 3rd musical tones
The signal forming channel is the melody playing sound on the keyboard 10.
And used for additional sound, and
The tone color data TC (0) to TC (3) regarding the channel is
Set to the data value that represents the tone of the drin. In response to the melody key depression on the keyboard 10, the above step 23
0 (key release event routine) turns on / off key for each mode
Routine MD3KON is read, the routine MD3KON
It starts at step 500 in FIG.
Key code KC (0), 0th tone color data TC (0), 0th tone
The volume data VOL (0) and the key-on signal KON indicate the melody message.
To the 0th tone signal forming channel in the signal generating circuit 43.
Be done. As a result, the 0th musical tone signal in the melody tone signal generating circuit 43 is received.
The signal forming channel responds to the arrival of each of the above key-on signals KON.
In response, start forming each tone signal, and
Output to the output lines L, C, R evenly. In such cases, the formation
The pitch of each tone signal output is the 0th key code KC
It is controlled by (0) and set to the performance melody key pitch.
The tone color of the same tone signal is stored in the 0th tone color data TC (0).
More controlled and set to the mandolin tone,
The volume of the sound signal is controlled by the 0th volume data VOL (0).
Key touch of the melody playing key (touch data
TCH) is set. Each output of the melody sound signal generation circuit 43
The tone signals output to the force lines L, C and R are output via the output circuit 44.
It is supplied to each speaker 45a-45c, and the speaker 45a-45c
The melody playing sound is pronounced in the mandolin tone.
It After the processing of step 502, the processing of steps 504 to 508 is performed.
From the previous additional sound pronunciation control channels (1 to 3)
The final channel data LSTCH that represents the routine MD3KON
Each time you execute, that is, every time you press the melody key,
It will be changed sequentially. Such final channel data LSTCH
After updating, at step 510, the LSTCH-th volume data VOL
(0) is the 0th volume data VOL related to the melody playing sound
Set to VOL (0) -20, which is 20 decibels lower than (0).
Then, in step 512, the key-on routine MD3KO for each mode is executed.
The execution of N ends. Next, step 252 (clock interrupt program) above.
RAM3) reads the mode-specific clock routine MD3CLK.
Then, the routine MD3CLK is executed in step 52 in FIG. 5B.
Start at 0, tempo count data at step 522
It is determined whether TCNT is an even value. In such cases,
If the tempo count data TCNT is an even value,
After step 524 based on the judgment of “YES” in page 522
However, the tempo count data TCNT is
If it is a numerical value, it is determined as “NO” in step 522.
In step 550, the clock routine MD3 for each mode is based on
When the CLK execution is completed, the actual processing of the routine MD3CLK is
The reason is not executed. As a result, the clock signal for each mode
Virtual MD3CLK processing must be done every 16th note
become. As described above, when it is determined to be “YES” in step 522,
Designated by final channel data LSTCH in step 524
The LSTCH-th key code KC (LSTCH) that is played is a melody
The 0th key code KC (0), which represents the playing sound, is set to
The 0th tone signal forming channel is keyed on at step 526.
Whether or not the inside tone signal is generated, that is, the melody
It is determined whether or not the key is being depressed. This judgment is
The key switch in the switch data storage section of the king memory 63
The melody key is pressed.
If it is in the key, the determination of “YES” in step 526 is made.
In step 528, the LSTCHth key code KC (LS
TCH), tone data TC (LSTCH), volume data VOL (LSTC)
H) and the key-on signal KON are in the melody sound signal generation circuit 43.
Is supplied to the LSTCH-th tone signal forming channel of
It In this case, the LSTCH-th key code KC (LSTCH) and
The tone color data TC (LSTCH) is the 0th melody performance sound.
Key code KC (0) and 0th tone color data TC (LSTCH)
Set to the same value and the LSTCH-th volume data VOL
(LSTCH) is the 0th volume data VOL related to the melody playing sound
20 decibels from (0) (Steps 532 and 546 to be described later)
By reason, VOL (LSTCH) is set to VOL (0) -15.
If it is set to 15 dB, it is set lower by 15 dB, so
For example, the first additional sound has the same pitch and the same sound as the melody playing sound.
20 decibels (or 15 decibels) from the same melody playing sound
Sound is started at a low volume. After the process of step 528, the final channel is processed in step 530.
Volume data VOL (LSTC
H) is 20 dB lower than the 0th volume data VOL (0)
It is determined whether or not there is. In such a case, both volume data VO
The relationship between L (LSTCH) and VOL (0) is VOL (LSTCH) = VOL
If (0) -20, "YES" in step 530.
Based on the determination that the level data LVL is
15 dB lower than the volume of the Roddy performance sound VOL (0)
Set to −15. Also, both volume data VOL (LSTCH), V
The relationship of OL (0) must be VOL (LSTCH) = VOL (0) -20
If so, the basis for the determination of “NO” in step 530 is
Then, in step 534, the level data LVL is the melody playing sound.
20 dB lower than the volume of VOL (0) -20
Be done. Next, by the processing of steps 536 to 540, the final channel
"1" in the order of data LSTCH 1 to 3 (however, 1 after 3)
Step by step. Such final channel data LSTCH
After updating, at step 542, the LSTCH th tone signal formation check
The tone signal that is being generated on the channel is
Is determined. This judgment is based on the melody message.

The execution of the mode-specific clock routine MD3CLK ends. Then, execute the previous clock routine MD3CLK for each mode.
When the time corresponding to the 16th note elapses from the
“YES” in step 522 of clock routine MD3CLK for each mode
It is determined that, after the processing of step 524, before step 526
It is determined whether or not the melody key from the
It In this case, if the melody key is being pressed, the above-mentioned
In step 528, the LSTCH th tone signal formation channel
The formation output of the additional sound signal in the channel is controlled to start.
In the formation of this additional sound signal, the previous step 536
~ 540 processing advances the final channel data LSTCH
And the previous processing of steps 530-534,546
Since the volume data VOL (LSTCH) has been switched,
The new additional tone signal is the stepped tone signal forming channel.
The volume is switched by the channel and the output is generated. This
As a result of the additional sound signal being formed and output, the additional sound is
As shown in Figure 5E, the performance is shifted by 16th notes.
15,20 decibel lower than the playing melody
The sound is sequentially generated at the set volume. Note that this additional sound is
Mandolin with the same pitch and tone as the playing melody
It is a timbre. In addition, a clock loop for each mode executed every 16th
In Chin MD3CLK, the above steps 536 ~ 544
From the tone signal forming channel where the pronunciation started
Only one tone signal formation channel with a large number (however,
(If the pronunciation start channel number is "3", the first number)
The generation stop of the additional sound signal in is controlled. That conclusion
As a result, as shown in Fig. 5E, the pronunciation time of each additional sound is 8 minutes.
It becomes equivalent to a mark and stops the sound of each additional sound.
Time shifts by 16th notes. Next, the melody that was pressed on the keyboard 10 as described above.
The D-key is released, and in response to the release, the above step 23 is performed.
Key off by mode in 4 (key release event routine)
Routine MD3KOF is read, the routine MD3KOF
It starts at step 560 in Fig.
