Abstract

PURPOSE:To improve operability by making a marker easy to set on the head of a bar or an arbitrary beat in the bar by setting the marker with more rough resolution in unit of bar or beat when it is set. CONSTITUTION:Playing data is read out by the interruption routine of a clock, and processing corresponding to the kind of the data is performed, and when block/repeat is set, routine from a repeat point A to a repeat point B is processed repeatedly. In the designation of the repeat points A, B, the marker is set at the head of the bar by quantize processing even when a SET switch is operated at any position in the bar. The quantize processing is performed not only in unit of bar but also in unit of beat or click of a metronome, which varies the operation arbitrarily. In other words, since the setting of the marker is performed with rough resolution in unit of bar or beat, the marker can be easily set on the arbitrary beat.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a marker quantizing device, and more particularly to a marker quantizing device suitable for use in designating an arbitrary position in performance data.

[0002]

BACKGROUND OF THE INVENTION Generally, in an automatic performance device, an arbitrary position in performance data can be designated, and an index indicating the designated arbitrary position is called a "marker".

By utilizing such markers, it is possible to realize, for example, a repeat function for automatically repeating a desired section of the performance data having markers set at both ends.

That is, the conventional automatic performance apparatus specifies a certain section (block) in the music stored in the automatic performance apparatus as performance data by a marker and repeats the section (hereinafter, referred to as a repeat function). The repeat function of repeatedly playing a block is called a block repeat function. In an automatic performance device equipped with such a block repeat function, a marker indicating the start / end position of the block repeat during playback of performance data (hereinafter referred to as the block repeat start point /
Mark the position of the end point as "Repeat Point"
Called. ), A marker setting device (hereinafter, repeat
A marker setting device for setting points is called a "repeat point setting instruction switch". ) Was set by operating.

[0005]

However, in the above-mentioned conventional automatic musical instrument, when storing the repeat points, the position at the time when the repeat point setting instruction switch is operated is stored with a resolution of one clock unit. Therefore, there is a problem that it is extremely difficult to accurately specify the beginning of a bar and an arbitrary beat in the bar.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to set a marker with a resolution of one clock when setting the marker. Instead, you can set markers with a coarser resolution, such as measures or beats, so that markers can be set reliably and easily at the beginning of a measure or at any beat in a measure, greatly improving operability. It is intended to provide a marker / quantize device.

[0007]

To achieve the above object, a marker quantizing device according to the present invention comprises a marker setting means for setting a marker at a predetermined position of performance data based on a predetermined resolution, and the marker setting means. The marker set by the means is provided with a quantizing means for shifting and resetting the marker based on a resolution lower than that of the marker setting means.

[0008]

The marker set by the marker setting means is reset by the quantizing means based on the resolution lower than that of the marker setting means.

Therefore, by setting the resolution of the quantizing means in units of measures or units of beats, it becomes possible to reliably and easily set a marker at the beginning of a measure or an arbitrary beat in the measure.

A slot 22 and a MIDI output device 24 for outputting the performance data stored in the RAM 16 reproduced by the control of the CPU 10 to a MIDI device such as an external sound source via a MIDI output terminal are connected.

That is, in this automatic performance device, the performance data stored in the memory card is stored in the RAM 16 by the CPU 10, and the performance data thus stored in the RAM 16 is reproduced by the CPU 10. Then, the performance data reproduced by the CPU 10 is output to an external sound source or the like by the MIDI output device 24, and a musical sound is emitted into the space, and a performance based on the performance data stored in the memory card is performed. Reproduced.

FIG. 2 shows an operation panel provided with the operation section 18, the display section 20, and the card slot 22 described above.

The operators provided in the operator section 18 include a PLAY switch 18a and a STOP switch.
The (stop) switch 18b, the REPEAT (repeat) switch 18c, and the SET (set) switch (repeat / point setting instruction switch) 18d are set.

The PLAY switch 18a is an operator for instructing the start of the automatic performance and, if operated during the automatic performance, for instructing a pause (PAUSE) of the automatic performance. When the PLAY switch 18a is further operated during the temporary stop, the automatic performance is restarted.

The STOP switch 18b is an operator for instructing to stop the automatic performance.

The REPEAT switch 18c is an operator for instructing to perform block repeat. This R
By operating the EPEAT switch 18c, it is possible to arbitrarily select whether or not to perform block repeat. Then, when the REPEAT switch 18c is operated again while the block repeat is set, the block repeat setting is canceled.

The SET switch 18d is an operator for setting a start point (hereinafter referred to as a repeat point A) and an end point (hereinafter referred to as a repeat point B) of a block when performing block repeat. is there. S
By operating the ET switch 18d, the repeat point A and the repeat point B can be set at an arbitrary position in the performance data with a resolution of 16th note.

The display section 20 displays a bar number, and in the present embodiment, an LCD (Liquid).
It is composed of a Crystal Display (liquid crystal display).

Further, FIG. 3 shows a data example for showing the data format of the performance data stored in the memory card. In this data format (described in hexadecimal notation), 1 byte following "FE" indicates waiting time (FExx: xx is time), and "FF" indicates end of performance data. Therefore, "FF" is always recorded in the performance data. Data other than the above is assumed to be MIDI data, and is transmitted as it is via the MIDI output device 24 to the MID.
It is output to the I output terminal.

In this embodiment, in order to facilitate understanding, the minimum resolution is set to "16th note" units and the tempo (the number of quarter notes played in 1 minute) is set to "120". , The time signature is fixed at "4/4".

By the way, the data example shown in FIG.
"C3" pitch note by "90 3C 40"
“FE 04” indicates the time for the note-on, and the time for one quarter note.
"40" indicates note-off of pitch "C3",
"FF" indicates the end of the performance data.

The operation and operation of the above-described automatic musical instrument according to the present invention will be described with reference to the flow charts. Although this automatic performance device normally repeatedly executes the main routine shown in FIGS. 4 and 5 at high speed, when an instruction to generate a clock interrupt is issued in the main routine, the automatic routine is executed at predetermined time intervals described later. Is interrupted by the clock interrupt, and the clock interrupt routine shown in FIGS. 7 and 8 is executed. When the execution of the clock interrupt routine is completed, the main routine is repeatedly executed again. Also, if an instruction to stop the clock interrupt is issued in the main routine, the clock interrupt will not be performed.

In the present embodiment, the tempo is set to "120" for the predetermined time for the clock interruption.
Since the minimum resolution is 16th notes,
It is "0.125 seconds". Therefore, in this embodiment, a clock interrupt is applied every "0.125 seconds".

First, the RA used in the following description
The register set in M16 will be described. In the following description, the contents (data) of each register are represented by the same label name unless otherwise specified.

(1) Pflag This is a flag indicating the state of performance, and is set to "0" when not playing and "1" when playing.

(2) Brep This is a flag showing the state of block repeat, and is set to "0" when the block is not being repeated and is set to "1" when the block is being repeated.

(3) ABflag This is a flag showing the setting state of the repeat point. When the repeat point A and the repeat point B are not set, "0" is set and the repeat point is set.
When only point A is set, "1" is set, and when both repeat point A and repeat point B are set, "2" is set.

(4) Mnumb This is a register for storing the measure number.

(5) A counter for obtaining the bar number from the Mcnt clock.

(6) Annum This is a register for storing the measure number of the repeat point A.

(7) Aaddr This is a register for storing the address of the repeat point A.

(8) Atime This is a register for storing the waiting time of the repeat point A.

(9) Atotal This register stores the total number of clocks at the repeat point A.

(10) Bnumb This is a register for storing the measure number of the repeat point B.

(11) Btotal This register stores the total number of clocks at the repeat point B.

(12) Wait Waiting counter.

(13) addr This is a register for storing the address of performance data.

(14) Song Data [addr] This is a register for storing an array in which performance data is stored.

(15) Maddr [maximum number of bars] This is a register for storing the address of the performance data at the beginning of the bar being processed.

(16) Wtime [maximum number of bars] This is a register for storing the waiting time from the leading bar line of the bar being processed.

(17) Total This register stores the total number of clocks from the beginning of the performance data to the performance data currently being processed.

Next, the main routine will be described with reference to FIGS. 4 and 5. When the power of the automatic musical instrument is turned on, first, in step S402, the CPU 1
0 initializes the above-mentioned register set in the RAM 16.

FIG. 6 shows a register initialization routine executed in step S402.
In step 602, Pflg is set to "0", in step S604 Brep is set to "0", and in step S606 ABflag is set to "0".
In step S608, Mnum is set to "1", in step S610 Wait is set to "1", in step S612 Mcnt is set to "0", and in step S614 addr is set to "0".

When the above processing is completed, step S6
Proceed to 16 and the memory card storing the performance data
It is determined whether the card is inserted in the card slot 22.

If the determination result of step S616 is negative (N), that is, if no memory card is inserted in the card slot 22, the determination process of step S616 is repeated without proceeding to the next process.

If the result of the determination in step S616 is affirmative (Y), that is, if a memory card is in the card slot 22, the process proceeds to step S618, the performance data is read, and the beginning of each measure is read. The address of the data is set to Maddr [bar number-1], and the waiting time from the bar line is set to Wtime [bar number-1].

That is, for example, the address of the first data of the first bar is set to Maddr [0 (= 1-1)], and the waiting time from the bar line of the first bar is Wtime.
It is set to [0 (= 1-1)]. Similarly, the address of the first data of the second bar is Maddr [1 (= 2-
1)], and the waiting time from the bar line of the second bar is set to Wtime [1 (= 2-1)]. In this way, Madd for all measures of performance data
r and Wtime are sequentially set.

When the process of step S618 is completed, the process proceeds to step S620 and Mnum is displayed on the display unit 20. Therefore, immediately after the initialization of the register, it is displayed that the processing object of the main routine is the performance data of the measure number "1" (the performance data of the first measure). When the process of step S620 is completed, the register initialization routine is completed and the process returns to the main routine.

Further, in the main routine, when the register initialization routine shown in FIG. 6 is completed, the process proceeds to step S404, and it is determined whether or not the PLAY switch 18a is pressed. This judgment result is affirmative, that is, P
If the LAY switch 18a is pressed, step S
In step 406, it is determined whether Pflag is set to "0".

If the result of the determination in step S406 is affirmative, that is, if "Pflag = 0: not being played", the process proceeds to step S408 and thereafter to start playing.

First, in step S408, the generation of a clock interrupt is instructed to activate the clock interrupt routine, and the performance data is reproduced in the clock interrupt routine as described later. Then, the process proceeds to step S410, Pflg is set to "1" to indicate that the performance is being performed, and then step S410 is performed.
You will proceed to 412.

On the other hand, when the result of the determination in step S406 is negative, that is, "Pflag = 1: playing", the process proceeds to step S414 and subsequent steps to pause (PAUS).
E) Processing will be performed.

First, in step S414, the generation of the clock interrupt is stopped and the execution of the clock interrupt routine is prohibited. As a result, the performance data is not reproduced in the clock interrupt routine.

When the processing of step S414 is completed, the process proceeds to step S416, where an instruction to immediately erase all the musical tones currently being generated is issued, and the MIDI output device 2
Output to an external sound source or the like by 4.

When the process of step S416 is completed, the process proceeds to step S418, and it is determined whether or not Brep is set to "1".

If the result of the determination in step S416 is negative, that is, if "Brep = 0" and block repeat is not in progress, the process directly proceeds to step S412.

On the other hand, if the result of the determination in step S416 is affirmative, that is, if "Brep = 1" and block repeat is in progress, the process proceeds to step S420 and the following steps.
Processing for automatically returning the start of reading the performance data to the repeat point A is performed.

First, in step S420, the value of Aaddr storing the address of repeat point A is set in addr indicating the address of performance data.

When the process of step S420 is completed, the process proceeds to step S422, where the Mnu storing the measure number is stored.
The value of Anum that stores the measure number of repeat point A is set in mb.

When the processing of step S422 is completed, the process proceeds to step S424, and the value of Atotal that stores the total clock number of repeat point A is set in the register Total that stores the total clock number of performance data. .

When the process of step S424 is completed, the process proceeds to step S426, and the waiting time counter Wait
A, which stores the waiting time for repeat point A,
A value obtained by adding "1" to the value of time is set, and the process proceeds to step S412.

By performing the above processing, PL
When the AY switch 18a is pressed to instruct the start of the performance, the reproduction of the performance data is started from the repeat point A.

Then, when the above-described processing of step S410 or step S426 is completed, or when the determination result of step S404 is negative, that is, when the PLAY switch 18a is not pressed, the process proceeds to step S412.

Then, in step S412, STOP
It is determined whether the switch 18b has been pressed.

If the determination result of step S412 is affirmative, that is, if the STOP switch 18b is pressed to instruct to stop the performance, the process proceeds to step S428.

In step S428, the generation of the clock interrupt is stopped and the execution of the clock interrupt routine is prohibited. As a result, the performance data is not reproduced in the clock interrupt routine.

When the process of step S428 is completed, the process proceeds to step S430, where an instruction is issued to immediately erase all the musical tones that are currently sounding, and the MIDI output device 2
Output to an external sound source or the like by 4. And
When the process of step S430 ends, step S40
Jump to 2.

It should be noted that the memory card from the card slot 22
Even when the card is removed, the STOP switch 1 described above
Processing similar to that when 8b is pressed is performed.

On the other hand, if the decision result in the step S412 is negative, that is, if the STOP switch 18b is not pushed, the routine proceeds to a step S432, and it is decided whether or not the REPEAT switch 18c is pushed.

If the determination result of step S432 is affirmative, that is, if the REPEAT switch 18c is pressed,
In step S434, it is determined whether Brep is set to "0".

If the result of the determination in step S434 is negative, that is, if "Brep = 1" and block repeat is in progress, the flow advances to step S436 to set Brep to "0" and block repeat is not in progress. Indicates that. Therefore, when Brep is read after the processing of step S436 is performed, “Bre” is read.
p = 0 ”.

That is, in the above case, since the REPEAT switch 18c is operated again during the block repeat, the set block repeat is released.

On the other hand, if the determination result of step S434 is affirmative, that is, "Brep = 0" and block repeat is not in progress, the process proceeds to step S438 and ABfl.
It is determined whether "2" is set in ag.

If the determination result of step S438 is affirmative, that is, "ABflag = 2", and repeat point A and repeat point B are set, the process proceeds to step S440.

In step S440, Brep is "1".
Is set to indicate that block repeat is in progress.

On the other hand, if the result of the determination in step S438 is negative, that is, if "ABflag = 2" is not satisfied, or if the process of step S436 or step S440 is completed, the process proceeds to step S442.

In step S442, the SET switch 1
It is determined whether or not 8d is pressed. If the result of this determination is affirmative, that is, if the SET switch 18d has been pressed, the flow proceeds to step S444 to determine the value of ABflag.

In step S444, "ABfla
If it is determined that “g = 0”, the repeat point A will be set in the processing of step S446 and thereafter.

That is, first, at step S446, the total number of clocks from the start of performance to the performance data being played when the SET switch 18d is pressed, Total.
Is divided by "16" because the resolution is 16th notes,
The value obtained by multiplying the divided quotient by 16 is set in Atotal. That is, the total number of clocks Total is divided by “16”, and the value obtained by rounding down the result of the division is multiplied by “16”. The value thus obtained is Ato
It is set to tal.

As a result, the number of clocks up to the beginning of the bar containing the performance data being played when the SET switch 18d is pressed is stored in Atotal.

To facilitate understanding, the explanation will be given with reference to the performance data which are all composed of sixteenth notes shown in FIG. 9. For example, when the total clock number Total from the beginning of the performance data is "17". , SET switch 1
If 8d is pressed, "Total = 17", and the operation performed in step S446 is "17/16".
= 1.0625 ”, but the quotient is“ 1 ”, so“ 1 × 16 = 16 ”, and“ 1 ”is given to Atotal.
6 ”is stored. And this "16" means SET
This represents the total number of clocks up to the performance data at the beginning of the bar including the performance data whose switch 18d is pressed.

When the process of step S444 is completed, the process proceeds to step S446, and Atime is set to Wtime [Ato
tal / 16].

That is, by "Atotal / 16", S
It is possible to obtain the bar number including the performance data that the ET switch 18d has pressed, and the waiting time from the bar line of the bar number is stored in Atime as the waiting time of the repeat point A. As a result, even when a rest exists at the beginning of the measure specified by the measure number, the block repeat performance can be started after the rest time has elapsed.

When the processing in step S448 is completed, the flow advances to step S450 to add Adrdr to Maddr [At
total / 16] is set.

That is, as described above, "Atotal / 1
6 ”, the bar number including the performance data whose SET switch 18d is pressed can be obtained, and the address of the performance data at the beginning of the bar of the bar number is set to Atime as the address of the repeat point A. Remember.

When the process of step S450 is completed, the process proceeds to step S452, and Anum displays "Total /
16 "is set.

That is, as described above, "Atotal / 1
6 ", it is possible to obtain the bar number including the performance data for which the SET switch 18d is pressed.
The bar number is stored in Anumb as the bar number of repeat point A.

Therefore, for example, as shown in FIG. 10, even if the SET switch 18d is actually pressed to set the repeat point A at the position α, the block repeat operation is performed by the quantizing processing in steps S446 to S452 described above. The repeat point A as the starting point will be reset to the position β.

When the process of step S452 is completed, the flow advances to step S454 to set ABflag to "1".
Is set to indicate that the repeat point A has been set, and then the process proceeds to step S404 to repeat the process.

In step S444, "AB
If it is determined that "flag = 1", step S45.
The repeat point B is set in the processing from 6 onward.

That is, first, in step S456,
"Total number of clocks from the start of performance to the performance data being played when the SET switch 18d is pressed, Total
Since l has a resolution of 16th note, it is divided by "16", and the value obtained by multiplying the divided quotient by 16 is set to Btotal. As a result, the number of clocks up to the beginning of the bar containing the performance data being played when the SET switch 18d is pressed is stored in Btotal.

Upon completion of the processing in step S456, the flow advances to step S458 to set Bnum to "Btotal / 1.
6 ”is set.

That is, as described above, "Atotal / 1
As in the case of "6", S is set by "Btotal / 16".
Since the bar number including the performance data pressed by the ET switch 18d can be obtained, the bar number is stored in Bnum as the bar number of the repeat point B.

Therefore, for example, as shown in FIG. 10, even if the SET switch 18d is actually pushed to set the repeat point B at the position γ, the quantizing process in steps S456 to S458 causes the block repeat to be repeated. The repeat point B as the end point will be reset to the position δ.

When the processing in step S458 is completed, the flow advances to step S460 to set ABflag to "2".
Is set to indicate that the repeat point B has been set in addition to the repeat point A, and the process proceeds to step S404 to repeat the process.

Further, in step S444, "A
If it is determined that “Bflag = 2”, the repeat point A and the repeat point B have already been set, and therefore the repeat point A and the repeat point B are quantized. No, the process proceeds to step S404 and the process is repeated.

Next, the clock interrupt routine executed by the clock interrupt every "0.125 seconds" will be described.

In this clock interrupt routine, first, in step S702, "1" is added to the counter Mcnt for obtaining the bar number from the clock, and the value of Mcnt is updated. Therefore, since "Mcnt = 0" is set in the register initialization routine, "Mcnt = 1" is set in step S702 immediately after the initialization.

When the process of step S702 is completed, the process proceeds to step S704, where "1" is added to Total,
Update the value of Total.

When the process of step S704 is completed, the process proceeds to step S706, and it is determined whether Mcnt is "17".

If the result of the determination in step S706 is affirmative, ie, "Mcnt = 17", then step S7
Proceed to 08, add "1" to Mnum and add Mnum
Update the value of.

That is, when 16 clocks (Mcnt = 16) have been counted for one bar, it means that "Mcnt = 17" means that one bar has been counted. Then, the first clock of the next bar 1 is counted. Therefore, Mnum
"1" is added to b to indicate the bar number of the next bar.

When the processing in step S708 is completed, the flow advances to step S710 to display the value indicated by Mnumb on the display section 20 as the bar number of the bar currently being processed.

When the process of step S710 is completed, the process proceeds to step S712, Mcnt is cleared to "0", and the process of a new measure designated by Mnum is performed. When the process of step S712 ends, the process proceeds to step S714.

On the other hand, if the determination result of step S706 is negative, that is, if Mcnt is not "17", the process proceeds to step S714.

In step S714, Brep is "1".
It is determined whether or not is set.

If the result of the determination in step S714 is negative, that is, if "Brep = 0" and block repeat is not in progress, the process proceeds to step S716.

On the other hand, if the result of the determination in step S714 is affirmative, that is, if "Brep = 1" and block repeat is in progress, the process proceeds to step S718 and Btota.
It is determined whether l and Total match.

If the result of the determination in step S718 is negative, that is, if Btotal and Total do not match,
It proceeds to step S716.

On the other hand, if the result of the determination in step S718 is affirmative, that is, if Btotal and Total match, it means that the clock interrupt processing up to the repeat point B has been completed, so that the processing from step S720 onward is performed. Processing for starting the clock interrupt processing from the repeat point A is performed.

That is, first, in step S720, Mnum
b is set to Anumb, and in Step S722, To
Atotal is set to tal, Aaddr is set to addr in step S724, and step S726
Then, the value obtained by adding "1" to Atime is set to Wait.

Steps S720 to S described above
When the next clock interrupt is applied by the processing of 726, the reproduction of the performance data is started from the repeat point A by the processing of step S716 and thereafter.

When the processing in step S726 is completed, the flow advances to step S728 to erase all the musical tones currently being generated (the musical tones produced based on the performance data recorded at repeat point B), and then to step S716. move on.

By the processing from step S716 onward,
The performance data specified by addr is output to an external sound source or the like by the MIDI output device 24.

First, in step S716, Wa
After subtracting “1” from it to update the value of Wait, the process proceeds to step S730.

In step S730, Wait is "0".
Or not. When the determination result of step S730 is negative, that is, when Wait is not “0”,
Since the waiting time has not ended, the clock interrupt processing is ended without performing the subsequent processing.

On the other hand, if the result of the determination in step S730 is affirmative, that is, if Wait is not "0", it means that the waiting time has ended, so the flow proceeds to step S732.
Whether the performance data in addr is "FF",
It is determined whether it is “FE” or MIDI data other than “FF” and “FE”.

If the result of the determination in step S732 is "FF", it indicates the end of the performance data.
In step S734, the clock interrupt is stopped.

When the process of step S734 is completed, the process proceeds to step S736, an instruction is issued to erase all the musical tones currently being sounded, and further the process proceeds to step S738 to initialize the register (FIG. 6) and execute the clock interrupt processing routine To finish.

Further, the judgment result of step S732 is "F
If it is "E", the performance data of addr is time data, so the procedure advances to step S740, and the performance data of addr (time data) is added to Wait.
Update the value of.

Upon completion of the processing in step S740, the flow advances to step S742 to add "1" to addr and add.
The value of dr is updated, the address is advanced by "1" and step S
Return to 730 and repeat the process.

Furthermore, the determination result of step S732 is
If the MIDI data is other than "FF" and "FE", the flow advances to step S744 to output the performance data (MIDI data) of addr by the MIDI output device 24.

Upon completion of the processing in step S744, the flow advances to step S746 to add "1" to addr and add.
The value of dr is updated, the address is advanced by "1" and step S
Return to 730 and repeat the process.

As described above, the performance data of the address indicated by addr is read out by the clock interrupt routine, and the type ("FF" or "F" of the performance data is read.
E ”or“ MIDI data ”) is performed.

At this time, if the block repeat is set, the performance data from the repeat point A to the repeat point B is repeatedly processed by the processes of steps S714 to S728.

When the repeat point A and the repeat point B are designated, even if the SET switch 18d is operated at any position in each measure, the main
By the quantizing process of steps S446 to 452 and steps S456 to S458 of the routine, the repeat point A and the repeat point B are always set at the head of the bar where the SET switch 18d is operated as shown in FIG. become.

In the above-described embodiment, the quantizing is performed in units of measures, but the present invention is not limited to this, and it may be performed in units of beats, clicks of a metonome, or the like. It may be allowed to change arbitrarily.

Further, in the above-described embodiment, when the quantize is performed, the repeat point is always set to the head position of the bar, no matter which position in the bar the SET switch 18d is pressed. However, without being limited to this, the following may be performed.

That is, as shown in FIG. 11, the quantization process in steps S446 to S452 and steps S456 to S458 of the main routine is performed by steps S1146 to S11.
52 and steps S1156 to S1158
As a result, with regard to repeat point A, if the SET switch is pressed below the midpoint of the measure, repeat point A will be set at the beginning of the measure, while SET after the middle
When the switch is pressed, the repeat point A is set at the beginning of the bar next to the bar.

Regarding repeat point B,
Even if the SET switch is pressed at any position in the measure, S
The repeat point B is always set at the beginning of the measure next to the measure in which the ET switch is pressed.

Further, as shown in FIG. 12, by changing the quantizing process in steps S456 to S458 of the main routine to steps S1256 to S1258, the repeat point A can be changed to the above-described embodiment. As shown, even if the SET switch 18d is pressed at any position in the bar, the repeat point is always set to the leading position of the bar, and the repeat point B is set at any position of the bar. Even if the SET switch is pressed, the repeat point B is always set at the beginning of the bar next to the bar where the SET switch is pressed.

The operator may arbitrarily set the combination of the quantizing processes.

Furthermore, in the above embodiment, in order to facilitate understanding, the minimum resolution is 16th notes, the tempo is fixed at "120", and the time signature is also fixed at "4/4". However, it is needless to say that the present invention is not limited to this, and the operator may arbitrarily set it.

[0136]

Since the present invention is constructed as described above, it has the following effects.

Marker setting means for setting a marker at a predetermined position of performance data based on a predetermined resolution, and quantizing means for shifting and resetting a marker set by the marker setting means based on a resolution lower than that of the marker setting means. And the marker set by the marker setting means is reset by the quantizing means based on a resolution lower than that of the marker setting means.

Therefore, by setting the resolution of the quantizing means in units of measures or units of beats, it is possible to reliably and easily set markers at the beginning of measures and arbitrary beats in measures.

That is, according to the marker / quantize device of the present invention, when the marker is set, the marker is not set uniformly by the resolution of one clock, but is set by a coarser resolution such as bar or beat. As a result, the marker can be reliably and easily set at the beginning of the bar or at an arbitrary beat in the bar, and the operability in setting the marker can be significantly improved.
