BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below. FIG. 1 is a block diagram of an electronic musical instrument to which the arpeggio sounding device of the present invention is applied. The CPU 1 is a ROM 2
The working area of the RAM 3 is used to control the entire electronic musical instrument based on the control program stored in. At the time of playing the keyboard, the CPU 1 fetches the note number, the key-on signal, etc. from the keyboard 4 via the detection circuit 4a, and sets the note number, velocity, and note-on / note-off to the tone generator circuit 5, thereby producing sound and muting. Perform processing. The tone generator circuit 5 generates a tone signal having a tone color set based on the note number, note-on, and velocity set by the CPU 1. The effect circuit 6 produces various effects on the tone signal generated by the tone generator circuit 5. Is added, and a sound is generated by the sound system 7. Further, the note number and the note-off are set so that the musical tone signal is attenuated or stopped to be muted.

In the arpeggio mode, the user sets an arbitrary key range on the keyboard 4 as the arpeggio key range, and the note number (pitch information) detected in this arpeggio key range is the arpeggio component sound. It is used to determine the pitch of. Then, the note number, velocity, and note-on / note-off are set in the tone generator circuit 5 based on the note number detected in this arpeggio key range and an arpeggio pattern to be described later, so that arpeggio sounding and mute are performed. The note numbers detected outside the arpeggio key range are used to generate musical tones for normal keyboard performance. To set the arpeggio key range, select a division point that divides the keyboard 4 into two parts, the bass side and the treble side, and set the bass side from this division point as the arpeggio key range, or the pitch range of the arpeggio key range. There is a method such as selecting directly.

Further, the CPU 1 takes in the input data from the switch 8 arranged on the operation panel through the detection circuit 8a, and switches the switch 8 to the arpeggio mode.
Performs various processes according to the operation. In addition, switch 8 is used for user input operations such as selection of arpeggio patterns.
In addition to the so-called GUI using a liquid crystal panel or the like of the display circuit 9
(Graphical user interface) is also used.

Further, the CPU 1 sets the information of the tempo input and designated in the timer 10, the timer 10 generates a clock signal (tempo clock) according to the set tempo, and the CPU 1 interrupts every 1 clock signal. Performs processing to process arpeggios. In this embodiment, the clock signal has 96 clocks corresponding to one beat of a quarter note, and one bar length is 384 clocks.

The external storage device 11 is a hard disk device,
A floppy disk device, a CD-ROM device, a magneto-optical disk device, etc. can be used for inputting and storing various data such as an arpeggio pattern. The interface 12 is a communication interface with a MIDI device or an external computer, and can exchange various data such as an arpeggio pattern with another MIDI device or an external computer.

FIG. 2 is a diagram showing a format of an arpeggio pattern. The arpeggio pattern consists of one set of five data, "timing", "gate time", "key number", "octave" and "velocity".
This is data for one pronunciation corresponding to one musical sound, and data for one pronunciation of the number of pronunciations corresponding to one bar is stored up to the last "end data". The "timing" is data representing a clock value corresponding to the tone generation start timing of the musical sound, and the "gate time" is data representing the time length (clock value) from the key-on to the key-off of the musical tone to be sounded.

The "key number" is data for determining the pitch of a musical tone to be produced. That is, a register corresponding to the "key number" is preset in the RAM 3, and the note number detected in the arpeggio key range is stored in the register, whereby the note number for the "key number" data is stored according to a predetermined rule. Assign Then, in the arpeggio tone generation process, the note number assigned to the "key number" in the arpeggio pattern is read from the register, and the note number is used as the note number that determines the pitch of the tone to be sounded. Note that this note number does not always become the pitch of the musical tone itself because it is also subjected to processing such as octave shift.

For example, when the number of keys that can be detected in the arpeggio key range is set to 4, the "key number" is "1".
Is a numerical value of "4", and the value of this "key number" is predetermined for each data of one pronunciation corresponding to the pitch change pattern of the arpeggio. Further, in this embodiment, the note numbers of the keys pressed in the arpeggio key range are assigned in order from the low note side note number to the younger "key number".

"Octave" is data for designating how many octaves the pitch is changed when changing the pitch instructed to be depressed in the arpeggio key range in units of octaves. For example, when the note number assigned to the “key number” is C3 and the value of “octave” is stored as “0”, the note of C3 is generated at the timing of producing the pitch of C3. I will let you pronounce it as it is at high pitch,
When the value of "octave" is stored as "+1", at the timing of producing the pitch of C3, the C3 is produced at the pitch of C4 which is shifted one octave up.

"Velocity" is data representing the velocity value (data used for controlling volume, etc.) of a musical tone to be sounded. When using the arpeggio function of the present embodiment on a keyboard capable of detecting a velocity value, the data relating to the above "velocity" is ignored and the velocity value corresponding to each key detected when a key is pressed is used. May be.

Next, an example of an arpeggio pattern and an arpeggio pattern will be described based on the specific examples of the arpeggio pattern shown in Table 1 below. In addition, "timing" in the table
Is the timing, "gate" is the gate, and "key"
Is the key number, "oct" is the octave, "ve
"l" represents velocity. The length of the arpeggio pattern is one bar (384 clocks), and as can be seen from the timing value, the arpeggio pattern in this example is a pattern that is generated every quarter note.

[0034]

[Table 1]

Now, the note number is B in the arpeggio key range.
If the keys C3, C3, E3, and G3 are pressed, the key number “1” (key = 1) is C3, the key number “2” (key = 2) is E3, and the key number “3” (k
G3 in ey = 3) has key number “4” (key = 4)
B3 is assigned to each (low order). Note that in the example of Table 1, the key value is set to only "1" or "2", and this arpeggio pattern is played with only two note numbers from the bass side of the key pressed in the arpeggio key range. It is a pattern that determines height.

For the first and second beats of Table 1, both key =
Since it is 1, the pitch is determined by the note number C3 assigned to this key = 1. The first beat is oct =
Since it is +0, the pitch is C3 as it is on the first beat as shown in FIG. However, since the second beat is oct = + 1, the pitch is C4 one octave higher than C3. Also, since both the third beat and the fourth beat are key = 2,
The pitch is determined by the note number E3 assigned to this key = 2, and since the third beat is oct = + 0, it becomes the pitch of E3 as it is, but the fourth beat is oct = + 1, so 1 of E3 is set. It becomes the pitch of E4 on the octave.

As described above, the note number of the key pressed in the arpeggio key range is referred to by the key number, and the note pitch of the note number is pronounced according to the arpeggio pattern, or the octave shift is performed to produce the sound. To do. That is, the note number of the depressed key is pitch information that determines the pitch of the constituent notes of the arpeggio.

In addition to the arpeggio sounding function, this electronic musical instrument has a groove function for adding a subtle feeling or groove feeling (expression like a habit of a musician playing) to performance data created by the user. Is equipped with. The arpeggio pattern also represents the time-series generation timing of musical tones, and has a format similar to performance data. Therefore, the groove function allows the arpeggio pattern to be changed.

(Groove Function) Here, the groove function will be described. The groove function changes the "timing", "gate time" and "velocity" data, which are the musical tone elements of the arpeggio pattern, so that you can adapt them to your playing style (swing, beat rock, other genres of songs), for example. The arpeggio pattern is changed based on the groove pattern data shown in FIG.

By the way, since the performance data input by the user through the keyboard performance or the like may deviate from the correct beat position in the musical tone generation timing, conventionally, the performance data generation timing is corrected to the correct beat position. The function of doing (known as "quantize") is known. Also in the groove function of this embodiment, first, the arpeggio pattern is quantized, and the quantized arpeggio pattern is changed. It should be noted that the "groove function user setting value" described later can be used to substantially prevent quantization.

As shown in FIG. 3, the groove pattern is data of "quantize value" for designating a beat as a reference for quantizing (data for designating a 16th note, an eighth note, a quarter note, etc.). The groove pattern has a set number of "groove data" corresponding to the "quantize value" corresponding to each reference beat. For example, in the case of a groove pattern for one measure with a quarter beat, the quantize value is 1
There are 16 sets for 6th notes, 8 sets for 8th notes and 4 sets for 4th notes. The processing unit based on the beat position designated by the "quantize value" is called "grid".

One set of groove data includes "clock shift", which represents the number of clocks for moving the tone generation timing of musical tones forward and backward, "gate time rate" which represents the ratio of increasing / decreasing the gate time of musical tone, and velocity of musical tone. It is composed of "velocity offset" data that represents a value that increases or decreases.

Further, in this embodiment, according to the setting value set by the user ("groove function user setting value"),
You can adjust the effect of the groove function including quantize. This "groove function user set value" is a value that determines the "quantize strength" as a value that determines the degree of quantize, and the value to which the clock shift value set in the groove pattern is applied to the sound that is produced. "Groove timing", "groove gate time" as a value that determines how much the gate time rate value set in the groove pattern is applied to the sound to be pronounced, and the velocity offset set in the groove pattern There is "groove velocity" as a value that determines how much the value of is applied to the sound to be pronounced.

FIG. 6 is a diagram showing an example of a groove pattern,
FIG. 7 is a diagram showing an example of changing the arpeggio pattern by the groove function, and a specific example of the groove function will be described based on the figure. The "quantize value" is for "quarter note", and the values of "quantize strength", "groove timing", "groove gate time" and "groove velocity" of "groove function user setting value" are all " 0.5 ".

The horizontal axis in FIG. 7 is the time (clock) for one bar.
And the vertical axis corresponds to velocity. First, FIG. 7 (A) shows the original arpeggio pattern. The tone of the first grid has a timing of 0 clock (bar start), a gate time of 48 clock, and a velocity of 30. In addition, the musical tones of the second grid have a timing of 24 from the second beat.
After the clock, the gate time is 24 clocks and the velocity is 20. The tone of the third grid has a timing of the beginning of the third beat, a gate time of 48 clocks, and a velocity of 30. The tone of the fourth grid has a gate time of 24 clocks and a velocity of 30 after 24 clocks from the fourth beat.

When the above arpeggio pattern (FIG. 7 (A)) is quantized, "quantized strength" is added to the deviation from the reference beat of the timing of each musical tone.
The timing is shifted by the amount multiplied by (“0.5”). That is, as shown in FIG. 7 (B), since the first grid and the third grid are originally in the same position because there is no deviation, the timings of the second grid and the fourth grid are 12 clocks (24 clocks × 24 clocks × 0.5) shifted forward and quantized.

Then, this quantized FIG. 7 (B)
For the arpeggio pattern of, based on the groove pattern and "groove function user setting value" in Figure 6,
The timing is changed as shown in FIG. 7 (C), the gate time is changed as shown in FIG. 7 (D), and the velocity is changed as shown in FIG. 7 (E). In this embodiment, the timing, gate time, and velocity are changed for each grid by the following equation. Also, the "groove function user set value" (groove timing, groove gate time, and groove velocity) is common to each grid.

[0048]

[Equation 1]

However, tN is the new timing, tO is the old timing, CS is the clock shift, GvT is the groove timing, gN is the new gate time, gO is the old gate time, GTR is the gate time rate, and GvGT is the groove gate time, vN. Is the new velocity, vO is the old velocity, VOF is the velocity offset, and GvV is the groove velocity.

FIG. 4 is a diagram conceptually showing the structure and operation of the main part in the embodiment. A plurality of types of arpeggio patterns and groove patterns are stored in the ROM 2 or the RAM 3, respectively. When the user sets the arpeggio mode, a plurality of arpeggio patterns and a plurality of groove patterns can be selected. Each arpeggio pattern and groove pattern is distinguished by a number or the like, and by selectively inputting this number and storing it in the RAM 3, each arpeggio pattern and groove pattern is selected. Further, the RAM 3 is provided with an arpeggio flag indicating the selection state of the arpeggio pattern. The value of the arpeggio flag is “0” when the arpeggio pattern is not selected, “1” when one is selected, "2" with two selected
Is set as.

In this embodiment, two arpeggio patterns can be selected, and a desired groove pattern can be selected corresponding to each selected arpeggio pattern. Then, the selected arpeggio pattern is changed as in the above-described specific example based on the groove function user setting value that is input and set and the selected groove pattern. The changed arpeggio pattern is stored in the RAM 3 as a first changed arpeggio pattern and a second changed arpeggio pattern, respectively. The groove pattern may not be selected according to claim 1, and in this case, the groove function is not used.

When storing the first and second modified arpeggio patterns, the timing1 flag and the timing that store the "timing" within each modified arpeggio pattern.
The ing2 flag is set to the timing value of the first data for one pronunciation (FIG. 2) in the modified arpeggio pattern. If the groove function does not change, the timing value of the first data for one sound in the selected arpeggio pattern is set.

Then, in the arpeggio mode, when a key press is detected in the arpeggio key range of the keyboard 4 by the key release process, the note number of the pressed key is assigned to the key number as described above, and the arpeggio performance is performed. (Interrupt processing) controls the timing1 flag, the gate1 flag, the timing2 flag, and the gate2 flag, and the key numbers of the first and second modified arpeggio patterns (the two originally selected arpeggio patterns if not modified), Generates a musical tone with a pitch corresponding to the key number based on the velocity. As a result, arpeggios are sounded with two types of arpeggio patterns.

FIG. 8 is a flowchart of the main loop of the control program in the embodiment, and FIGS. 9 to 11 are flowcharts of the subroutine and the interrupt process. The operation of the embodiment will be described based on each flowchart. In addition,
In the following description and flowchart, the flags used for control are represented by the following labels, and each flag and the storage contents thereof are represented by the same label unless otherwise specified.

Then, arpeggio, timing1, timing
Initialization such as setting “0” to each of the flags 2, gate1, gate2, time, and run is performed. Next, in step S2, it is determined whether or not the arpeggio mode is selected. If the arpeggio mode is selected, the arpeggio setting process of FIG. 9 is performed in step S3, the process proceeds to step S4, and the arpeggio mode is selected. If not, the key pressing and releasing process of FIG. 10 is performed in step S4, and the process proceeds to step S5. In step S5, other processing such as operation detection of the panel switch 8 and processing corresponding to the operation is performed. Then, in step S6, it is determined whether or not the end is designated by power-off or the like, and if designated, the processing is performed. Ends, and if not specified, returns to step S2. In addition,
Arpeggio mode selection processing is performed by other processing in step S5, and it is determined in step S2 whether or not the arpeggio mode has been selected.

In the arpeggio setting process of FIG. 9, the arpeggio flag is set to "1" in step S11,
In step S12, a process for the user's input operation is performed to determine the arpeggio key range, and in step S13, the process for the user's input operation is performed to select the first arpeggio pattern. Next, in step S14, it is determined whether or not the groove pattern is set to be used by performing a process corresponding to an input operation by the user. If not used, the process proceeds to step S17, and if used, the first pattern is used in step S15. Performs the process of selecting the groove pattern of. Then, in step S16, the first

Gate time, key number, octave, velocity)
Is designed to read sequentially by updating this pointer using a predetermined pointer. When data is read, as in the case where the first timing value is set to timing1 or timing2, the next data (in the above example, Set the pointer to (gate time).

By the above processing, the first arpeggio pattern and the second arpeggio pattern can be selected. In addition, the first arpeggio pattern and the second arpeggio pattern can be changed based on desired groove patterns. In the above embodiment, there are various selection methods depending on the combination of the arpeggio pattern and the groove pattern, but the case of selecting the first and second arpeggio patterns (a plurality of arpeggio patterns) corresponds to the embodiment of claim 1. To do .

The arpeggio pattern used for the arpeggio sounding in the following processing is the selected arpeggio pattern itself when the groove pattern is not changed, and the changed arpeggio pattern (changed when the groove pattern is changed). Arpeggio pattern). Therefore, in the following description of the flow chart, both the arpeggio pattern without change and the changed arpeggio pattern are simply referred to as "arpeggio pattern" unless otherwise specified.

In the key release processing of FIG. 10, step S21
It is determined whether or not there is a key press, and if there is no key press, the process proceeds to step S28, and if there is a key press, the arpe in step S22.
It is determined whether or not ggio = 0. arpeggi
If o = 0, the arpeggio pattern has not been selected, so sound generation processing (processing corresponding to normal keyboard performance) corresponding to the depressed key is performed in step S23, and then step S23 is performed.
Proceed to 28. If arpeggio = 0 is not satisfied, it is determined in step S24 whether or not the key is in the arpeggio key range.
If the key is not pressed in the arpeggio key range, the same process is performed in step S23. If the key is pressed in the arpeggio key range, run = 1 is set in step S25 and the process proceeds to step S26.
In step S26, the note number corresponding to the depressed key is set in correspondence with the key number that has not been assigned yet from the younger key number (next key number), and the time flag is set to "0" (time = 0)
And set to step S28.

Note that, even when a plurality of keys are pressed substantially simultaneously in the arpeggio key range, or when a plurality of keys are sequentially pressed, this key release processing is performed every time a key press is detected. By repeating this, the note numbers that are pressed are assigned to the predetermined key numbers (for example, "1" to "4") in order from the low tone and the keys with the smallest key numbers. Also, while the key is pressed in the arpeggio key range, run = 1. In the process of step S28 and subsequent steps, which will be described below, run = 0 if no key is pressed in the arpeggio key range.

In step S28, it is determined whether or not there is a key release. If there is no key release, the key release processing is ended, and if there is a key release, it is determined in step S29 whether run = 1. If run is not 1, the key is released in a range other than the arpeggio key range (all the key range when not in the arpeggio mode), so the mute process corresponding to the key released in step S201 is performed to perform the key release process. finish. If run = 1, it is determined in step S202 whether or not the key is released in the arpeggio key range. If it is not released in the arpeggio key range, the same processing as described above is performed in step S201, and the arpeggio key range is determined. If the key release is No., the assignment of the key number corresponding to the note number released in step S203 is released, that is, the key number is released, and the process proceeds to step S204.

Here, by the processing of step S203,
The key number to which the released key number is assigned has no corresponding note number, so that nothing is sounded at the sounding timing specified by this key number. That is a rest. Note that this step S2
The process of 03 may be a process of re-assigning keys other than released keys (keys that are still pressed) to key numbers in the order of bass.

In step S204, it is determined whether or not there is a key depressed in the arpeggio key range. If there is a key depressed in the arpeggio key range, the key release / release process is terminated and the key is depressed. If there is no key, r in step S205
The un flag is set to “0” (run = 0), the read position of each arpeggio pattern is set to the head (pointer to the head) in step S206, and the key release processing is ended. That is, when there are no more keys in the arpeggio range,
At that point, the data read position of the arpeggio pattern is set to the head, and the timing is set in the timing1 flag or the timing2 flag to prepare for the start of the next arpeggio.

The interrupt process of FIG. 11 is started by the clock signal from the timer 10. First, it is determined in step S31 whether run = 1. If run = 1, the key is pressed in the arpeggio key range. Not so step S3
If it is run = 1, the key is pressed in the arpeggio key range, so in step S32 arpeggio = 0.
Or not. If arpeggio = 0, the arpeggio pattern is not selected, so the process proceeds to step S309. If arpeggio = 0 is not set, the arpeggio pattern is selected, and thus step S33.
Then, it is determined whether timing1 = time.

If timing1 = time is not satisfied, the current timing (time) is not the timing of sounding in the first arpeggio pattern, so the routine proceeds to step S37, and if timing1 = time is satisfied,
Since it is the timing of sounding in the first arpeggio pattern, the data following the timing data of the first arpeggio pattern is sequentially read out in step S34,
The note number of the pitch corresponding to the key number (if there is an octave shift, the shifted note number. The same applies below), the velocity value and the note-on are output to the tone generator circuit 5 to perform sound generation processing. Next, in step S35, the read gate time value is set in the gate1 flag, and in step S36, the next timing value is timing.
The 1 flag is set and the process proceeds to step S37.

In step S37, it is determined whether or not gate1 = 0. If gate1 = 0, it means that the tone of the musical sound of the first arpeggio pattern has been silenced. The note number and note-off of the tone pitch to be output are output to the tone generator circuit 5 to mute the sound, and the process proceeds to step S301. ga
If te1 = 0 is not satisfied, the value of gate1 is decremented by "1" in step S39 to advance the counting of the gate time, and the process proceeds to step S301.

In step S301, arpeggio =
It is determined whether or not 2, and if arpeggio = 2 is not satisfied, it means that only the first arpeggio pattern is selected. Therefore, the process proceeds to step S309, and arpeggi
If o = 2, the second arpeggio pattern is selected, and thus timing2 = ti in step S302.
It is determined whether or not it is me. Note that step S302
The process from step S308 to the second arpeggio pattern is the same as the process from step S33 to step S39 for the first arpeggio pattern.

If timing2 = time is not satisfied, the process proceeds to step S306. If timing2 = time is determined, at step S303, tone generation processing is performed on the pitch data corresponding to the timing data of the second arpeggio pattern and the key number of the set based on the velocity value. To do. next,
In step S304, the read gate time value is set to ga
te2, in step S305 the next timing value is set in timing2, and in step S306 g
It is determined whether or not ate2 = 0. gate2 = 0
If so, in step S307, a mute process is performed on the pitch corresponding to the key number, and the process proceeds to step S309.
If gate2 = 0 is not satisfied in step S308
The value of 2 is decremented by "1" and the process proceeds to step S309.

In step S309, automatic performance processing is performed. That is, although automatic accompaniment is performed in automatic performance processing, automatic accompaniment is processing that sequentially reads time-series performance data based on a clock signal to generate a musical tone, similar to arpeggio pronunciation, and is included in the interrupt processing. There is.
The automatic performance process in step S309 is a substantial process when the automatic accompaniment mode is set. However, when the automatic accompaniment mode is set in the arpeggio mode, for example, the bass and rhythm of the performance data are set. It is also possible to reproduce the track of and play the arpeggio and the bass and rhythm.

Upon completion of the automatic accompaniment process, it is determined in step S310 whether or not time <384, and t
If time <384, it is in the middle of a measure, so the value of time is advanced by “1” in step S311 to end the interrupt processing. If time <384, the time for one measure has elapsed. In step S312, the time flag is set to "0" (time = 0), and the interrupt process ends.

By the above processing, two kinds of arpeggios are sounded based on the note number corresponding to the key pressed in the arpeggio key range and the first and second arpeggio patterns, so that the arpeggio function is enhanced, You can pronounce expressive arpeggios.

Further, since the arpeggio pattern can be changed to the changed arpeggio pattern by the groove pattern, the function of the arpeggio is enhanced and the arpeggio can be pronounced with rich expressiveness.

In the above embodiment, a plurality of arpeggio patterns are independently selected. However, as shown in FIG. 12, for example, a plurality of track data of the 1st to n-th tracks are set as one set. You may make it use what formed the arpeggio pattern for each of the track data (it calls a "track arpeggio pattern"). Each track data of this track arpeggio pattern includes data of “track number” indicating a track number and data of “timbre number” for setting a tone color of each track data, and other “timing”, The data for one pronunciation consisting of "gate time", "key number", "octave" and "velocity" is the same as in the case of FIG.

The control in the case of using this track arpeggio pattern is almost the same as that of the above-described embodiment, and for example, the sound generation processing and the mute processing based on the arpeggio pattern in steps S33 to S39 in FIG. To all track data. In this case, a flag for storing timing data of each track is used for each track corresponding to the processing of steps S33 and S36 of FIG.
Similarly, a flag for storing the gate time data of each track is used for each track corresponding to the processes of step S36, step S38, and step S39.

In the above-mentioned embodiment, the tone color of the tones to be produced is one type of tone color selected for the keyboard performance, but when the above track arpeggio pattern is used, arpeggio tone generation is performed with a different tone color for each track. be able to.

Also, for a novice user, when simultaneously producing sounds with a plurality of arpeggio patterns, it is a difficult task to select another arpeggio pattern that is familiar with a certain arpeggio pattern from the plurality of arpeggio patterns. is there. However, by using the above track arpeggio pattern, it is possible to prepare a plurality of arpeggio patterns as a set in advance by using a plurality of track data, so that, for example, even a beginner user can familiarize themselves with each other as a music flow. It is possible to easily carry out arpeggio pronunciation by using a plurality of different arpeggio patterns, and it is possible to realize more versatile arpeggio pronunciation with easy operation.

When the track arpeggio pattern is used, the arpeggio sound corresponding to a desired track may be set to be muted.

In the above embodiment, for example, "1" to "4".
The note numbers of the keys pressed in the arpeggio key range are assigned to the four key numbers of, and the pitch of the arpeggio is determined by the note number corresponding (assigned) to the key number of the arpeggio pattern. Therefore, the number of keys pressed is the number of key numbers (4).
If the number is smaller, some key numbers will not be assigned. However, since the arpeggio pattern may include a key number to which the note number as described above is not assigned, a rest is set in such a case.
Further, instead of rests, a predetermined note number such as the highest note or the lowest note of a depressed key may be duplicated and assigned to a plurality of key numbers.

In the arpeggio pattern, only the timing, gate time, velocity, etc. are used without using the key number, and the note number of the key pressed in the arpeggio key range and the order in which the key is pressed are stored. The pitch of each tone of the arpeggio pattern may be sequentially determined according to a predetermined rule in which the order of the pitch of the note number and the order of key depression are combined. Further, in this case, a plurality of rules for determining the pitch may be determined and a desired rule may be selected.

Although the arpeggio pattern and groove pattern in the embodiment are data of one bar length,
Not limited to this, data having a plurality of bar lengths may be used.

In the embodiment, the user sets the arpeggio key range, but the arpeggio key range may be determined in advance.

In the embodiment, when the groove pattern is selected, the groove pattern is used to change the data in the selected arpeggio pattern, and the arpeggio sound is generated based on the changed arpeggio pattern. However, while the arpeggio is being sounded, refer to the groove pattern grid according to the timing,
The groove effect may be sequentially applied to the tones to be sounded, based on the data in the groove pattern.

In the embodiment, the groove pattern is selected for each of the two arpeggio patterns, but the present invention is not limited to this and the data may be changed for the two arpeggio patterns by the same groove pattern. In addition, two or more groove patterns are selected for one arpeggio pattern, two or more modified arpeggio patterns are created, and simultaneous arpeggio sounds are generated based on the created plurality of modified arpeggio patterns. May be.

Also, when an arpeggio pattern is selected, a groove pattern (so-called “recommended groove pattern”) that is familiar to the selected arpeggio pattern is displayed, so that even a beginner can easily change the arpeggio pattern. May be allowed.

In the embodiment, two types of arpeggio musical tones are generated by using two arpeggio patterns selected by the user based on the pitch information (key depression pitch information) of the key pressed in the arpeggio key range. Although they are sounded at the same time, different key depression pitch information may be given to the two selected arpeggio patterns to generate arpeggio musical tones.

For example, of the key-depression pitch information in the arpeggio key range, the key-depression pitch information corresponding to the even-numbered keys from the low tone side is used for the first arpeggio sounding, and the key-depression pitch information corresponding to the odd-numbered keys. Is used for the second arpeggio pronunciation. Also, the first
And the second key depression key range are set, and the key depression pitch information in each key range is used for the corresponding first and second arpeggio sounds. Alternatively, a plurality of key-pitch pitch information key-depressed in the arpeggio key range is used for the first arpeggio sounding, and pitch information shifted one octave above or below the key-depressed key is used to generate a second pitch. The arpeggio may be pronounced.

In the embodiment, the younger "key numbers" are assigned to the key depression pitch information in the arpeggio key range in the order of lower notes, but the invention is not limited to this. You may make it allocate in order from.

In the embodiment, the case where two kinds of arpeggio patterns or groove patterns are used is explained, but the present invention is not limited to this, and a plurality of arpeggio patterns or groove patterns of two or more kinds are used. You may make it pronounce.

The format of the arpeggio pattern in the embodiment is a format of “event + absolute time” in which the occurrence time of the event in which the arpeggio musical sound is generated is represented by the absolute time in the song or bar, but the present invention is not limited to this. "Event +" that represents the time when the event occurred by the time (duration in clocks) from the previous event
It may be in the form of "relative time". Further, the arpeggio pattern may be in the form of “pitch (rest) + note length” in which the arpeggio pattern to be generated is expressed by the pitch and note length of a note or a rest and rest length. Alternatively, a so-called "solid method" in which a memory area is secured for each minimum resolution of a musical tone generation event (clock in the embodiment) and data such as key numbers and velocities are stored in a memory area corresponding to the time when the musical tone generation event occurs. Format, such as

The method of changing the tempo of the arpeggio sounding is to change the period of the tempo clock (interrupt signal), or to change the value of the timing data according to the tempo while keeping the tempo clock period as it is, 1 Any value may be used, such as changing the value for counting the timing data (for example, the number to be reduced) in the processing of one time.

In the above embodiment, the arpeggio pattern,
