[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic performance device,
More specifically, the present invention relates to an automatic performance device capable of copying arbitrary performance data and thereby creating new performance data.

[0002]

2. Description of the Related Art Conventionally, in an automatic performance device, as one of the methods of creating new performance data from existing performance data, existing performance data (hereinafter referred to as "original performance" as a source of new performance data is referred to as appropriate. It is known to copy data).

As such a copying method, there are a method of copying all the original performance data and a method of copying a part of the original performance data. When copying a part of the original performance data, it is necessary to specify a copy range for the original performance data and execute the copy.

Therefore, in the case of creating new performance data by combining a plurality of parts of the original performance data, a copy range is specified for each of the plurality of parts and copying is performed to create new performance data. It was something that had to be created.

In addition, when a part of a plurality of original performance data is combined to create new performance data, a copy range is specified for each of the plurality of original performance data, and copying is performed. It was necessary to create new performance data.

[0006]

By the way, in the conventional automatic performance apparatus, when designating the copy range when copying the performance data, the measure number displayed on the display provided on the operation panel is used. It is necessary to specify the number of measures while referencing, and there is a problem in that the work of specifying the copy range must be complicated.

In particular, when copying a plurality of parts of the original performance data or copying a plurality of original performance data, the copy range specifying operation of specifying the number of measures while referring to the measure number is copied. However, there is a problem in that the work of specifying the copy range becomes even more complicated.

Further, when combining the performance data copied from the original performance data, the copy destination area can be specified by designating the number of measures while referring to the measure number displayed on the display provided on the operation panel. However, there is a problem that the designation work is complicated as in the designation of the copy range.

The present invention has been made in view of the above-mentioned various problems of the prior art, and an object of the present invention is to provide an automatic operation with improved operability in copying performance data. It is intended to provide a musical instrument.

[0010]

In order to achieve the above object, an automatic performance apparatus according to the present invention comprises a reproducing means for reproducing performance data and a storage means capable of storing the performance data reproduced by the reproducing means. While the performance data is being reproduced by the reproducing means, only the operator for designating an arbitrary range of the performance data being reproduced in synchronization with the reproduction of the performance data and the performance data in the range designated by the operator are described above. And a storage control means for storing in the storage means.

[0011]

[Operation] While reproducing the performance data by the reproducing means,
By designating the desired range of the performance data with the operator, the storage control means can store the performance data in the desired range in the storage means, so that the range of the performance data to be copied can be easily designated.

The performance data in the event data format is stored in advance in each track. That is, the performance data stored in each track is an event data consisting of pitch data indicating the pitch of a note to be emitted and pitch data indicating the pitch of a note to be emitted.
It is composed of data and time data indicating the occurrence time of event data.

Here, the pitch data is represented by a pitch name and an octave. For example, "C3" is

1-00 ", the pitch data is" C3 ", and the pitch length data is" 96 ". This is" 0 clock at the 1st beat of the 1st measure ". It indicates that a tone of "quarter note" corresponding to the length of the number of clocks of "96 clocks" is emitted at the pitch of "C3 (C tone of the third octave)".

The RAM 16 is assumed to be backed up by a built-in battery (not shown) of this automatic musical instrument so that the stored contents can be retained even if the power is cut off. In FIG. 3, predetermined performance data is stored in advance at the time of factory shipment, and the user can appropriately rewrite the performance data into desired performance data by using the conventionally known performance data writing technology to RAM. It is done like this.

A tempo interrupt routine (not shown) is executed each time the PU 10 arrives.

That is, in this automatic musical instrument, the main routine is usually repeated at high speed, but an interrupt is generated each time the tempo clock generated by the tempo clock generator 18 arrives at the CPU 10. The tempo interrupt routine is executed, and after the execution of the tempo interrupt routine, the main routine is repeated again. Since the tempo clock generator 18 generates the tempo clock periodically, the tempo interrupt routine is also executed periodically.

In the main routine and the tempo interrupt routine, only the process relating to the writing of the performance data stored in the tracks 1 to 3 to the track 4 which is the subject of the present invention will be described in detail. The detailed description of the processing generally performed by the automatic performance device is omitted.

It is assumed that all the performance data stored in the three tracks of track 1 to track 3 are read out and reproduced in synchronization. It should be noted that from the speaker 28, musical tones according to the performance data stored in the tracks 1 to 3 may be simultaneously emitted, or a musical tone may be emitted from the speaker 28 by providing a track selection switch for emitting the sound. It is assumed that any of the tracks 1 to 3 may be selected as the track to be performed, but the detailed description of the processing outside the scope of the present invention is omitted as described above.

Further, in the following description, the writing of the performance data stored in the tracks 1 to 3 to the track 4 is a so-called “overwrite”, and the performance data by the latest writing is always written in the track 4. Shall be stored.

Furthermore, in the following description, when any two or all three of the track 1 button 44 to the track 3 button 48 are pressed at the same time, the track button with the smaller track number has priority. I shall.

First, the main routine shown in FIG. 4 will be described. When the power of the automatic musical instrument is turned on by the operation of the main switch 56, the initial setting is performed in step S402. In this initial setting, all the above-mentioned flags set in the RAM 16 are cleared to "off" and the values of all counters are set to "0". Further, the values of various registers such as MOD are also cleared to "0".

When the initial setting process of step S402 is completed, the process proceeds to step S404, the operating state of the mode selection switch 54 is detected, and the value indicating the selected mode is set to MOD.

Further, when the process of step S404 is completed, the process proceeds to step S406, and it is determined whether or not the start flag is "ON".

If the determination result of step S406 is affirmative (Y), that is, if the start flag is "ON", the process proceeds to step S416, while step S40.
If the determination result of 6 is negative (N), that is, if the start flag is "off", the process proceeds to step S408.

The start flag is set in step S4, which will be described later, by pressing the start button 34.
At 14, it is set to "on".

In step S408, the record
It is determined whether the button 42 has been pressed. Then, the determination result of step S408 is positive, that is, the record
If the button 42 has been pressed, step S410.
, The record flag is set to "ON", and then the process proceeds to step S412.

On the other hand, if the result of the determination in step S408 is negative, that is, if the record button 42 has not been pressed, the process proceeds directly to step S412.

In step S412, start
It is determined whether the button 34 has been pressed. Then, the determination result of step S412 is affirmative, that is, the start
If the button 34 has been pressed, step S414
Then, the start flag is set to "ON", and then the process proceeds to step S416.

On the other hand, if the determination result in step S412 is negative, that is, if the start button 34 has not been pressed, the process directly proceeds to step S416.

In step S416, a stop
It is determined whether the button 36 has been pressed. The determination result of step S416 is affirmative, that is, the stop button 3
If 6 is pressed, the process proceeds to step S418,
The record flag is cleared to "off", the process further proceeds to step S420, the start flag is cleared to "off", and the process proceeds to step S422.

On the other hand, if the determination result in step S416 is negative, that is, if the stop button 36 has not been pressed, the process directly proceeds to step S422.

In step S422, the track 4 is tracked according to the setting status of the track 1 flag to the track 3 flag.
A flag process for selecting performance data to be written in is performed. This flag processing is executed by a flag processing routine (not shown) which is a sub routine of the main routine.

When the flag processing in step S422 is completed, the flow advances to step S424 to display the operation states of various operators on the display 30 and the like. When the process of step S424 ends, the process returns to step S404, and the main routine is repeatedly executed until the power is turned off by the main switch 56 and the power supply to the automatic musical instrument is cut off.

In the above-mentioned flag processing routine, the track flag corresponding to each track button is turned "on" and "off" in response to the operation. For example, if the track 1 button 44 is pressed, the track 1 flag is set to "on", and if it is not pressed, it is set to "off". Similarly, when the track 2 button 46 is pressed, the track 2 flag is set to "on", and when it is not pressed, it is set to "off", and the track 3 button 48 is pressed. If so, set the track 3 flag to “on”,
If not pressed, set to "off". When each process is completed, the process returns to the main routine.

Next, each time the tempo clock generated by the tempo clock generator 18 arrives at the CPU 10, the tempo interrupt routine is activated. In this tempo interrupt routine, first, according to the MOD value set in step S404 of the main routine,
Mode 1, mode 2, mode 3 or mode 4 is selected, and interrupt processing 1 routine (FIG. 6), interrupt processing 2 routine (FIG. 9), interrupt processing 3 routine (FIG. 14), interrupt processing 4 routine (FIG. 17) ) Is executed, and when these interrupt processes are completed, the process returns to the main routine.

Next, the interrupt processing 1 routine, the interrupt processing 2 routine, which execute the processing for each mode,
The interrupt processing 3 routine and the interrupt processing 4 routine will be described separately for each mode.

[Mode 1] Mode 1 means that the user stores track 1 to track 3 in which performance data is stored in advance.
Is selected as appropriate, and the track 1 corresponding to the selected track
Only the buttons 44 to 3 are operated while the buttons 44 to 3 are operated.
In this mode, the performance data stored in the tracks 1 to 3 corresponding to the button 48 is copied to the track 4 according to the time data of the performance data.

In this mode 1, the tracks 1 to 3 and the track 4 operate so that when the start button 34 is pressed, they are reproduced and stored in synchronization.

FIG. 5 shows an operation example of the mode 1, in which the track 1 button 44 to the track 3 button 48 corresponding to the track 1 to the track 3 are pressed while the track 1 button 3 is pressed. The situation in which the performance data stored in the tracks 1 to 3 corresponding to the button 44 to the track 3 button 48 is written to the track 4 is shown.

That is, when the value of the tempo clock counter is "A", the track 2 button 46 is pressed (O
N), when the value of the tempo clock counter is “B” and the track 2 button 46 is released (OFF), the performance data of the first measure (2A) and the second measure (2B) of track 2 is , Are written in the first bar and the second bar of the track 4 at the timing of being read as they are.

Then, from the time when the value of the tempo clock counter when the track 2 button 46 is released is "B", the performance data of the track 2 is not written to the track 4, but this tempo clock counter is not written. Track 1 button 44 is pressed when the value of "1" is "B" and the track 1 button 44 is released when the value of the tempo clock counter is "C". Track 4 at the timing when the performance data of measure (1C) is read as it is
It is written in the 3rd measure of.

Then, from the time when the value of the tempo clock counter is "C" when the track 1 button 44 is released, the performance data of track 1 is no longer written to track 4.

Further, when the value of the tempo clock counter is "D", the track 2 button 46
When is pressed and the value of the tempo clock counter is “E”, the track 2 button 46 is released, so that the performance data of the second measure (2E) of track 2 is
It is written in the fifth bar of the track 4 at the timing of being read as it is.

Then, from the time when the value of the tempo clock counter when the track 2 button 46 is released is "E", the performance data of the track 2 is not written to the track 4, but this tempo clock counter is not written. Track 3 button 48 is pressed when the value of is equal to "E" and the track 3 button 48 is released when the value of the tempo clock counter is equal to "F". Measures (3F) and 7
The performance data of the measure (3G) is written in the measure 6 and measure 7 of the track 4 at the timing of being read as it is.

From the time when the value of the tempo clock counter when the track 3 button 48 is released is "F", the performance data of the track 3 is not written to the track 4, but this tempo clock counter Track 1 button 44 is pressed when the value of "1" is "F", and track 1 button 44 is released when the value of the tempo clock counter is "G". Track 4 at the timing when the performance data of measure (1H) is read as it is
It is written in the 3rd measure of.

As described above, in the mode 1, since it is possible to easily select and copy only an arbitrary portion of the original performance data, it is possible to combine the performance data of a plurality of musical pieces,
It is possible to easily create new performance data such as a medley performance.

FIG. 6 shows an interrupt processing 1 routine for realizing such a mode 1. Playback and storage are performed in synchronization with tracks 1 to 3 and 4 as described above. Behave like.

In this interrupt processing 1 routine,
First, in step S602, it is determined whether or not the start flag is set to "ON".
If the determination result of step S602 is negative, that is, if the start flag is cleared to "OFF", the process directly returns to the tempo interrupt routine.

On the other hand, if the result of the determination in step S602 is affirmative, that is, if the start flag is set to "ON", the flow proceeds to step S604 to perform sound generation processing, and then to step S606.

In step S606, the record
Determine if the flag is set to "on". If the determination result in step S606 is negative, that is, if the record flag is cleared to "OFF", the process proceeds to step S620, the tempo clock counter is incremented by "1", and then the process returns to the tempo interrupt routine.

On the other hand, if the result of the determination in step S606 is affirmative, that is, if the record flag is set to "on", the flow advances to step S608 to determine whether or not the track 1 flag is set to "on". To do.

If the determination result of step S608 is affirmative, that is, if the track 1 flag is set to "ON", the process proceeds to step S610, where the current tempo in the performance data stored in track 1 The performance data at the location corresponding to the clock counter value
The data and the time data are used as a unit and written in the location corresponding to the current tempo clock counter value of the track 4. When the process of step S610 is completed, the process proceeds to step S620, the tempo clock counter is incremented by "1", and then the process returns to the tempo interrupt routine.

On the other hand, if the decision result in the step S608 is negative, that is, if the track 1 flag is cleared to "OFF", the flow advances to a step S612 to check whether or not the track 2 flag is set to "ON". to decide.

If the determination result of step S612 is affirmative, that is, if the track 2 flag is set to "ON", the process proceeds to step S614, where the current tempo in the performance data stored in track 2 is set. The performance data at the location corresponding to the clock counter value
The data and the time data are used as a unit and written in the location corresponding to the current tempo clock counter value of the track 4. When the process of step S614 ends, the process proceeds to step S620, the tempo clock counter is incremented by "1", and then the process returns to the tempo interrupt routine.

On the other hand, if the decision result in the step S612 is negative, that is, if the track 2 flag is cleared to "OFF", the flow advances to a step S616 to check whether or not the track 3 flag is set to "ON". to decide.

If the determination result of step S616 is affirmative, that is, if the track 3 flag is set to "ON", the process proceeds to step S618, and the current tempo in the performance data stored in track 3 The performance data at the location corresponding to the clock counter value
The data and the time data are used as a unit and written in the location corresponding to the current tempo clock counter value of the track 4. When the process of step S618 is completed, the process proceeds to step S620, the tempo clock counter is incremented by "1", and then the process returns to the tempo interrupt routine.

On the other hand, if the decision result in the step S616 is negative, that is, if the track 3 flag is cleared to "OFF", the process proceeds to a step S620 as it is, after incrementing the tempo clock counter by "1", the tempo is increased. Return to the interrupt routine.

In this way, by simply pressing the track 1 button 44 to the track 3 button 48, the desired position of the performance data stored in the tracks 1 to 3 is appropriately copied and combined. Can be stored in track 4.

[Mode 2] Mode 2 means that the user stores track 1 to track 3 in which performance data is stored in advance.
Is selected as appropriate, and the track 1 corresponding to the selected track
Only the buttons 44 to 3 are operated while the buttons 44 to 3 are operated.
In this mode, the performance data stored in the tracks 1 to 3 corresponding to the button 48 is sequentially copied to the track 4 asynchronously without the reproduction of the tracks 1 to 3 and the recording on the track 4 being synchronized.

That is, in this mode 2, tracks 1 to 3 are reproduced in synchronization with each other, but track 4 is track 1 button 44 to track 3 button 4
Data is sequentially stored based on the copy instruction by pressing 8.

FIG. 7 shows an operation example of the mode 2 in which the track 1 button 44 to the track 3 button 48 corresponding to the track 1 to the track 3 is pressed only while the track 1 button 44 is pressed. The situation is shown in which the performance data stored in the tracks 1 to 3 corresponding to the button 44 to the track 3 button 48 are sequentially and continuously written to the track 4.

That is, as shown in the above-mentioned interrupt processing 2 routine and its sub-routine copy 1 processing routine to copy 6 processing routine, the performance data stored in tracks 1 to 3 is stored in the tempo clock counter. And the performance data is written to the track 4 in synchronization with the copy clock counter.

Then, the copy clock counter is
The track 1 button 44 to the track 3 button 48 are incremented only while they are being pressed.
Writing to the track 1 button 44 to track 3
Only when one of the buttons 48 is pressed, the performance is synchronized with the performance of the performance data stored in the tracks 1 to 3. As a result, only while the track 1 button 44 to the track 3 button 48 corresponding to the track 1 to the track 3 are being pressed, the track 1 to the track 3 corresponding to the pressed track 1 button 44 to the track 3 button 48 are changed. The stored performance data is sequentially and continuously written without providing a blank portion on the track 4. At this time, the time data of the performance data is rewritten so as to correspond to the value indicated by the copy clock counter.

Explaining with reference to FIG. 7, when the track 2 button 46 is pressed at the same time as the start of the performance in which the value of the tempo clock counter is "A", it is synchronized with the increment of the tempo clock counter. Copy
The clock counter is incremented. Therefore,
When the track 2 button 46 is released when the tempo clock counter value is "B", the performance data of the first bar (2A) and the second bar (2B) of track 2 are read out as they are. It is written in the first bar and the second bar of the track 4 at the specified timing.

Then, from the timing when the value of the tempo clock counter when the track 2 button 46 is released is "B", the performance data of the track 2 is no longer written to the track 4, but this tempo clock counter Since the track 1 button 44 is pressed when the value of is at the timing "B", the increments of the tempo clock counter and the copy clock counter are continued in synchronization. Therefore, the tempo clock
When the track 1 button 44 is released when the counter value is “C”, the third measure (1) of track 1 is released.
The performance data of C) will be written in the third bar of the track 4 at the timing of being read as it is. Then, from the time when the value of the tempo clock counter is "C" when the track 1 button 44 is released, the performance data of track 1 is no longer written to track 4.

Thereafter, from the timing when the value of the tempo clock counter is “C” to the timing when the value of the tempo clock counter is “D”, the track 1 button 4 is pressed.
When none of the track 4 to track 3 buttons 48 is pressed and the timing of the tempo clock counter is "D", the track 2 button 46 is pressed.

Therefore, between the timing when the value of the tempo clock counter is "C" and the timing when the value of the tempo clock counter is "D", the tempo clock counter is incremented, but the copy The clock counter is not incremented. And
When the track 2 button 46 is pressed at the timing when the value of the tempo clock counter is "D", the increment of the copy clock counter is started in synchronization with the increment of the tempo clock counter.
Therefore, when the track 2 button 46 is released when the tempo clock counter value is "E", the performance data of the 5th bar (2E) of track 2 is read as it is. It is written in the fourth bar of track 4.

From the time when the value of the tempo clock counter when the track 2 button 46 is released is "E", the performance data of track 2 is no longer written to track 4, but this tempo clock counter Since the track 3 button 48 is pressed when the value of is equal to "E", the increments of the tempo clock counter and the copy clock counter are continued in synchronization. Therefore, the tempo clock
When the track 3 button 48 is released when the counter value is "F", the 6th bar (3
The performance data of F) and 7th bar (3G) are written in the 5th bar and the 6th bar of the track 4 at the timing of being read out as they are. Then, from the time when the value of the tempo clock counter when the track 3 button 48 is released is “F”,
The performance data of is no longer written to track 4.

FIG. 8 shows the performance timing of the performance data stored in the track 4 created by the operation described above with reference to FIG. 7. The performance data stored in the track 4 is The time data of the performance data is rewritten so as to correspond to the value indicated by the copy clock counter and stored in the track 4, and is continuously read in synchronization with the progress of the tempo clock counter. become.

Therefore, in mode 2, track 1
Since any part of the performance data stored in the track 3 can be easily selected and copied, performance data of a plurality of musical pieces can be combined to easily create new performance data such as a medley performance. You can Moreover, in mode 2, the performance data newly created in track 4 by copying the performance data of tracks 1 to 3 is sequentially packed in the track 4 from the front in time, unlike in the case of mode 1. The performance data newly created on the track 4 has no silence. Therefore, in the mode 2, it is not necessary to perform the troublesome process of editing and deleting the silent portion from the performance data newly created on the track 4.

In this mode 2, the pressed track 1 is started from the timing of the beat next to the timing at which the track 1 button 44 to the track 3 button 48 are pressed.
Even if the performance data stored in the track 1 to the track 3 corresponding to the button 44 to the track 3 button 48 is written to the track 4 and the track 1 button 44 to the track 3 button 48 are not pressed, they are pressed. The writing of the performance data to the track 4 is continued until the timing of the beat next to the lost timing. In this way, by writing the performance data to the track 4 in beat units, as compared with the writing of the performance data to the track 4 in clock units as in the case of mode 1, the track 1 buttons 44 to Track 3 button 4
It is possible to prevent a slight deviation in clock units at the timing of pressing 8.

As described above, in the mode 2, only the simple operation of pressing the track 1 button 44 to the track 3 button 48 makes it possible to appropriately copy a desired portion of the performance data stored in the track 1 to the track 3. The combined performance data can be continuously stored and played without providing a blank portion on the track 4.

[Mode 3] Mode 3 is a mode relating to the case of performing an automatic rhythm performance. Here, the term "automatic rhythm performance" means automatic rhythm performance data (event data and the time at which the event data is generated) consisting of a rhythm pattern having a predetermined number of measures (4 measures in this embodiment) as performance data. Data) and automatic rhythm performance data are sequentially repeated to perform a loop performance. In the present embodiment,
Performance data is stored in tracks 1 to 3 by a rhythm pattern of four measures, and the performance data stored in tracks 1 to 3 can be written in track 4 as appropriate. Then, the performance data stored in the tracks 1 to 4 is played in synchronization with the tempo clock counter, and when it is played up to the 4th measure, it returns to the beginning and is repeatedly played.

Since a technique itself for repeatedly reading a predetermined number of performance data to perform an automatic rhythm performance is known, its detailed description will be omitted.

In the mode 3, the user appropriately selects the tracks 1 to 3 in which the performance data is stored in advance and operates the track 1 button 44 to the track 3 button 48 corresponding to the selected track. During this period, the performance data stored in the tracks 1 to 3 corresponding to the operated track 1 button 44 to the track 3 button 48 is copied to the track 4 according to the time data of the performance data.

In the mode 3, the tracks 1 to 3 and the track 4 operate so that when the start button 34 is pressed, they are reproduced and stored in synchronization with each other.

FIG. 12 shows an operation example of the mode 3, in which the track 1 button 44 to the track 3 button 48 corresponding to the track 1 to the track 3 are pressed while the track 1 button 3 is pressed. Button 44 to Track 3 Track 1 to Track 3 corresponding to Button 48
The situation is shown in which the performance data stored in is written in the track 4.

That is, when the value of the tempo clock counter is "A", the track 2 button 46 is pressed and the value of the tempo clock counter is "B" (the last clock (the end of the fourth measure). Clock)) when
When the track 2 button 46 is released, the performance data of the 4th bar (2D) of the track 2 is written in the 4th bar of the track 4 at the timing of being read as it is.

Then, from the time the track 2 button 46 is released and the value of the tempo clock counter is "B", the performance data of track 2 is no longer written to track 4, and at the same time, the beginning of the first measure. Then, the performance data stored in tracks 1 to 3 is reproduced.

Further, when the value of the tempo clock counter is "C", the track 3 button 48 is pressed, and when the value of the tempo clock counter is "D", the track 3 is pressed. When the 3 button 48 is released, the performance data of the second bar (3B) and the third bar (3C) of the track 3 are written in the second bar and the third bar of the track 4, respectively, at the timing of being read out as they are. .

Then, from the time when the value of the tempo clock counter is "D" when the track 3 button 48 is released, the performance data of track 3 is no longer written to track 4.

Further, when the value of the tempo clock counter is "E", the performance data stored in tracks 1 to 3 is reproduced by returning to the beginning of the first measure. , This tempo clock
When the track 1 button 44 is pressed when the counter value is "E", and when the track 1 button 44 is released when the tempo clock counter value is "F", the track 1 button 1 Performance data of measure (1A)
It is written in the first measure of the track 4 at the timing of being read as it is.

Then, from the time when the value of the tempo clock counter is "F" when the track 1 button 44 is released, the performance data of track 1 is no longer written to track 4.

FIG. 13 shows the performance timing of the performance data stored in the track 4 created by the operation described above with reference to FIG.
The performance data stored in the track 4 is continuously read in synchronization with the progress of the tempo clock counter in the order of bar numbers of the performance data stored in the tracks 1 to 3.

Therefore, when selecting an arbitrary portion of the performance data of a rhythm pattern to be repeatedly played and creating performance data of a new rhythm pattern to be repeatedly played, the selection is made in the order of bar numbers. However, in mode 3, new performance data is created in the original correct measure number order without being affected by the selected order. Therefore, in mode 3, a new rhythm pattern can be created easily and quickly.

The situation is shown in which the performance data stored in is written in the track 4.

That is, as shown in the above-mentioned interrupt processing 4 routine and copy 7 processing routine to copy 12 processing routine, the performance data stored in tracks 1 to 3 are played in synchronization with the tempo clock counter. The performance data is written to the track 4 in synchronization with the copy clock counter.

Then, the copy clock counter is
The track 1 button 44 to the track 3 button 48 are incremented only while they are being pressed.
Writing to the track 1 button 44 to track 3
Only when one of the buttons 48 is pressed, the performance is synchronized with the performance of the performance data stored in the tracks 1 to 3. As a result, only while the track 1 button 44 to the track 3 button 48 corresponding to the track 1 to the track 3 are being pressed, the track 1 to the track 3 corresponding to the pressed track 1 button 44 to the track 3 button 48 are changed. The stored performance data is sequentially and continuously written without providing a blank portion on the track 4. At this time, the time data of the performance data is rewritten so as to correspond to the value indicated by the copy clock counter.

Referring to FIG. 15, when the track 2 button 46 is pressed at the timing when the tempo clock counter value is "A", the copy clock
The counter increment starts and is synchronized with the tempo clock counter increment. Therefore, when the track 2 button 46 is released when the tempo clock counter value is "B", the performance data of the 4th measure (2D) of track 2 is tracked at the same timing as it is read. It is written in the first measure of 4 and copied.

From the timing when the value of the tempo clock counter when the track 2 button 46 is released is "B", the performance data of track 2 is not written to track 4, and at the same time, the beginning of the first measure. Then, the performance data stored in tracks 1 to 3 is reproduced.

Further, when the track 3 button 48 is pressed when the value of the tempo clock counter is "C", the increment of the copy clock counter is restarted, and the tempo clock counter Synchronize with increment. Therefore, when the track 3 button 48 is released when the tempo clock counter value is "D", the performance data of the second bar (3B) and the third bar (3C) of the track 3 remains unchanged. At the read timing, the second and third measures of the track 4 are sequentially written and copied.

Then, from the time when the value of the tempo clock counter is "D" when the track 3 button 48 is released, the performance data of track 3 is no longer written to track 4.

Furthermore, when the value of the tempo clock counter is "E", the performance data stored in tracks 1 to 3 is reproduced by returning to the beginning of the first measure. , At the same time, track 1
When button 44 is pressed, the copy clock counter increments again and the tempo clock counter
Synchronize with the counter increment. Therefore, when the track 3 button 48 is released when the tempo clock counter value is "F", the performance data of the first measure (1A) of track 1 is read at the timing when it is read as it is. It is written in the 4th bar of 4 and copied.

Then, from the time when the value of the tempo clock counter is "F" when the track 1 button 44 is released, the performance data of track 1 is not written to track 4.

FIG. 16 shows the performance timing of the performance data stored in the track 4 created by the operation described above with reference to FIG.
The time data of the performance data stored in the track 4 is rewritten so as to correspond to the value indicated by the copy clock counter, and the time numbers of the performance data stored in the tracks 1 to 3 are stored in the bar numbers. regardless of,
In the order written in track 4, the tempo clock,
It will be read continuously in synchronization with the progress of the counter.

As described above, in the mode 4, the performance data of the tracks 1 to 3 are sequentially pasted in time and copied to the track 4, so that the performance newly created in the track 4 is reproduced. There is no silence in the data. Therefore, in mode 4, track 1
Through, it is possible to easily and quickly create a new rhythm pattern by arbitrarily combining the performance data stored in the track 3, and edit or delete a silent portion from the performance data newly created in the track 4. There is no need to perform the troublesome process.

That is, in this embodiment, the performance data is stored in the tracks 1 to 3 by the rhythm pattern of 4 bars, and the performance data stored in the tracks 1 to 3 is written in the track 4 as appropriate. Is made possible. Then, the performance data stored in the tracks 1 to 4 is played in synchronization with the tempo clock counter, and when it is played up to the 4th measure, it returns to the beginning and is repeatedly played.

Further, the copy clock counter is incremented only while the track 1 button 44 to the track 3 button 48 are pressed, and the copy clock counter of the track 4 is copied.
The storage operation is performed in synchronism with the clock counter, and therefore, the track 4 is regarded as the track 1 to the track 3 only when any of the track 1 button 44 to the track 3 button 48 is turned on. Operates synchronously.

In this mode 4, the performance data is written to the track 4 from the timing of the beat next to the timing at which the track 1 button 44 to the track 3 button 48 are pressed, and the track 1 button 44 to the track 4 are recorded. Even if the 3 button 48 is not pressed, the writing of the performance data to the track 4 is continued until the timing of the beat next to the timing when the button is not pressed. As described above, by writing the performance data to the track 4 in units of beats, as compared with the writing of the performance data to the track 4 in units of clocks as shown in the case of the mode 3, the track 1 buttons 44 to 44 can be used. Track 3 button 48
It is possible to prevent a slight deviation in clock units at the timing of pressing.

FIG. 17 shows an interrupt processing 4 routine for realizing such a mode 4. Tracks 1 to 3 are reproduced in synchronization with each other, and track 4 is synchronized with the reproduction thereof. Operates so that it can be stored.
