[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a minus one playing device, and more particularly to a minus one playing device capable of performing an effective minus one playing.

[0002]

2. Description of the Related Art Conventionally, in an electronic musical instrument, a musical tone is not generated by an automatic performance for a specific part among a plurality of parts which can be simultaneously performed by an automatic performance. It has been performed to generate a musical tone of a part in which a musical tone is not generated by an automatic performance.

[0003] This is a so-called minus one performance, in which the performance of a specific part is designated from the automatic performance of music, and the designated part (minus.
Instead of automatically playing one part), it is possible for the player to perform his or her own performance using a predetermined instrument such as a keyboard device, and to perform an ensemble with the automatic performance. Therefore, such minus one performance is extremely effective when individual players practice ensemble or the like.

[0004]

However, in the above-mentioned conventional technique, when performing the minus one performance, the automatic performance of the minus one part is completely muted and muted. Therefore, the minus one that should be performed when the minus one performance is not performed
There is a problem that the performer cannot listen to the automatic performance in the part.

[0005] For this reason, the performer himself cannot perform the performance by referring to the automatic performance performed by the minus one part, so that the novice cannot perform an efficient ensemble practice.

The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to reduce the volume of automatic performance of an arbitrary part such as a minus one part. When playing a minus one, or when monitoring a part that focuses on and listens to an arbitrary part, the performer can automatically play any part, such as the minus one part. Is intended to provide a minus one performance device that can be easily heard.

[0007]

In order to achieve the above object, according to the first aspect of the present invention, a first performance data input means for inputting performance data of a plurality of parts; A second performance data input means for inputting performance data independently of the one performance data input means; and an arbitrary part among a plurality of parts indicated by the performance data input by the first performance data input means. Part designation means for designating the part, and the part designated by the part designation means may be any one of a plurality of parts indicated by the performance data input by the first performance data input means. A sole volume setting means commonly used to arbitrarily set the volume of the part designated by the designating means, and a plurality of sound volume setting means inputted by the first performance data input means; Control means for controlling the volume of a tone generated based on the performance data of the part designated by the part designating means out of the performance data of the part to the volume set by the volume setting means. did. According to a second aspect of the present invention, the first performance data input means for inputting the performance data of a plurality of parts, and the performance data is input independently of the first performance data input means. Second performance data input means, a part designating means for designating an arbitrary part from a plurality of parts indicated by the performance data inputted by the first performance data input means, and a part designating means designated by the part designating means. To set the volume of the part designated by the part designating means arbitrarily, regardless of whether the part is any of the plurality of parts indicated by the performance data inputted by the first performance data inputting means. Among the performance data of a plurality of parts input by the first performance data input means, Control means for controlling the volume of the musical tone generated based on the performance data of the specified part to the volume set by the volume setting means; and the performance data input by the first performance data input means and A musical sound generating means for generating a musical sound in accordance with the musical performance data inputted by the second musical performance data input means.

[0008]

According to the first aspect of the present invention,
An arbitrary part such as a minus one part is designated from a plurality of parts indicated by the performance data input by the first performance data input means by the part designating means,
Since the volume of the designated part is controlled to the volume arbitrarily set by the volume setting means, the part designating means among the plurality of parts indicated by the performance data input by the first performance data inputting means is used. Only the designated part can control its volume to an arbitrary volume set by the volume setting means. Furthermore, since the performance data can be input by the second performance data input means independently of the first performance data input means, for example, the performance data input by the first performance data input means indicates the performance data. When the volume of the part selected as the minus one part by the part designating unit is set to a relatively low volume, the second performance data input unit selects the part as the minus one part. By inputting the performance data of the part corresponding to the performed part and performing the performance by the player, the player can perform his own performance while listening to the minus one part as a reference for the performance. According to the second aspect of the present invention, the performance data input by the first performance data input means and the performance data input by the second performance data input means by the musical tone generating means are used. A tone can be generated accordingly.

A PU 12 and a read-only memory (ROM) 14 storing a predetermined program for controlling the entire operation and various tone control parameters such as a volume parameter and a tone color parameter used when executing the program, as will be described later. A random access memory (RAM) 16 as a working area in which various registers necessary for executing a program by the CPU 10 are set, and the operation is controlled by the CPU 12 and signals are input / output. I do.

The control unit 10 receives a MIDI signal A output from the automatic performance device 18 via a bus and transmits the MIDI signal A to the control unit 1.
0, and a MIDI signal B output from a keyboard device 22 operated by the player.
Circuit 24 for inputting the control signal to the control unit 10, an operation unit 26 having various operations described later, and a tone generation unit 28 for generating a tone signal by a method of reading a waveform memory are connected. . Further, an audio device 30 including an amplifier, a speaker, and the like is connected to the musical sound generation unit 28.

Therefore, in this electronic musical instrument, the MID
M is supplied to the CPU 12 from the I circuit 20 and the MIDI circuit 24.
When a musical sound generation start / stop instruction by the IDI signal is input, the CPU 12 responds to the input MIDI signal based on various musical sound control parameters such as a volume parameter and a tone color parameter set in various registers of the RAM 16. Then, the musical tone information indicating the pitch, tone color, volume, etc. to be generated / stopped is input to the musical tone generating unit 28. Then, the tone generator 28 generates a tone signal based on the tone information input from the CPU 12, and the tone signal is
Is emitted into the space as a musical sound.

Hereinafter, each of the above components will be described in detail.

The operation unit 26 includes a part selection operation unit 32 (INC switch and DEC switch) for selecting a minus one part, and selects a part by appropriately operating these switches. ), Minus one on for performing minus one performance and minus one off for not performing minus one performance, and the volume level of minus one part is controlled. A minus one part volume control 36, an all part volume control 38 for controlling the volume level of all parts by the automatic performance device 18,
Lights up when minus one on is selected by minus one operator 34,
It is turned off when minus one off is selected by the one operator 34, and includes a light emitting diode (LED) 40 for checking the setting state of the minus one operator 34.

That is, by operating the INC switch or the DEC switch of the part selection operator 32, a specific part for performing minus one performance is selected from all the parts which generate musical tones based on the MIDI signal A from the automatic performance device 18. It is made possible to arbitrarily select a minus one part.

Here, "parts" correspond to musical tones of a plurality of timbres simultaneously generated by the musical tone generator 28, and correspond to so-called musical instrument components in an orchestra. Then, for each part, the timbre of the tone generated in the part is set separately. Each part is set to have a one-to-one correspondence with each MIDI channel in the MIDI signal. That is, MI
Assuming that the DI channel is 16 channels, 16 parts are also set. For example, the MIDI channel “1” corresponds to the part “1”, and the MIDI channel “2” corresponds to the part “2”. Is configured.

The tone generator 28 can simultaneously produce a plurality of parts. Each part has a priority set, and the tone generation channels are truncated in order from the part having the lowest priority. It is configured to be. That is, when there is a new tone generation request from the automatic performance device 18 or the keyboard device 22, the tone generation is forcibly stopped in order from the tone generation channel of the part having the lowest priority, and the part for which the tone generation is requested is emitted.

In the ROM 14, various tone control parameters such as a volume parameter, a tone color parameter, and an effect parameter are set. The content stored in the ROM 14 is read out by the CPU 12 and stored in a working area of the RAM 16 or the like.

The RAM 16 has a part memory area 16a for storing the minus one part selected by the operation of the part selection operator 32, and is set to minus one on by the operation of the minus one operator 34. A minus one memory area 16b indicating whether the data is stored or set to minus one off;
A volume parameter indicating the volume level set by the minus one part volume operator 36 is stored.
A one-part volume parameter memory area 16c and an all-part volume parameter for storing a volume parameter indicating a volume level set by the all-part volume operator 38;
A memory area 16d is set.

Further, although not shown, the instrument (tone color) setting of the musical tone generated in each part is stored for each part (by an operation element (not shown) provided in the operation element section 26). The content is set.). At the time of musical tone generation, the tone color of the musical tone is controlled by referring to the tone color parameter stored in the ROM 14 based on the instrument (tone color) setting status stored in the RAM 16.

Next, the operation of the minus one performance device will be described. When the operation unit 26 is operated, the part selection operation unit 32 and the minus one operation unit 3
4. Input to the CPU 12 operator information indicating which one of the minus one part volume operator 36 and the all part volume operator 38 has been operated. In this way, the CPU 12 having input the operation element information by the operation of the part selection operation element 32 stores the minus one part selected by the operation of the part selection operation element 32 into the part Write to the memory area 16a.

Further, the CPU 12 to which the operator information has been input by operating the minus one operator 34, uses a well-known technique, and selects the minus one on or minus one selected by operating the minus one operator 34.・ Turn off the minus one memory area 1 of RAM16
Write to 6b.

Further, the CPU 1 to which the operator information is input by operating the minus one part volume operator 36
2 writes a volume parameter indicating a volume level set by operating the minus one-part volume operator 36 into the minus one-part volume parameter memory area 16c of the RAM 16 by a known technique.

Similarly, the CPU 12 to which the operation information has been input by operating the all-part volume operation element 38 uses a known technique to change the volume parameter indicating the volume level set by operating the all-part volume operation element 38, RAM16
Is written to the all part sound volume parameter memory area 16d.

In order to perform the minus one performance by the minus one performance device, first, the INC switch or the DEC switch of the part selection operator 32 is operated to select the minus one part.

Next, the minus one-part volume control 36 is operated to arbitrarily set the minus one-part volume level.

By performing the setting operation as described above, the volume level of the minus one part played by the automatic performance device 18 can be arbitrarily set, and the performer can use the keyboard device 22 to set the minus level. You will be able to play a part that is equivalent to one part. At this time, the volume level of the minus one part by the keyboard device 22 is based on a known technique, regardless of the operation of the minus one part volume operator 36.
It can be set arbitrarily by the keyboard device 22 or an operator (not shown) of the minus one playing device.

FIG. 2 is a flowchart showing a minus one event processing routine. This minus one event processing routine is performed by the minus one operator 3
The operation is started by a minus one event generated by the minus one on or minus one off operation of No. 4.

First, when a minus one event is detected, it is determined in step S202 whether or not the operation by the minus one operator 34 is minus one on. If the determination result in step S202 is affirmative (Y), that is, if the minus one on operation is performed by the minus one operator 34, the process proceeds to step S204.

In step S204, the minus one part, which is the part selected by operating the part selection operator 32, is changed so as to have the lowest priority, and the MIDI channel of the keyboard device 22 is assigned the highest priority. Assign to the higher ranked part.

The technique for setting each part in accordance with the above-mentioned priority order is a known technique as disclosed in Japanese Patent Application Laid-Open No. 64-1933 filed by the present applicant. Although detailed description is omitted, for example, it can be performed according to a procedure described below.

For example, it is assumed that the RAM 16 is provided with a part table as shown in FIG.
In this part table, the priority order is first part → second part
It is set to be lower in the order of part → third part →..., MIDI channel, required number of tone generation channels, tone number, reserved number (the minimum guaranteed number of non-truncated tone generation channels) for each part In the state shown in FIG. 3A, eight parts have already been set.

It is assumed that the keyboard device 22 is set to the MIDI channel 10.

As shown in FIG. 3A, when eight parts have already been set, for example, the first part having the highest priority is set as the minus one part by operating the part selection operator 32. Suppose you have selected. Then, since the priority order of the eight parts has already been set, the selected first part is changed and set to the ninth part so that the priority order of the selected first part is the lowest. That is, the stored contents of the first part, which is the minus one part played by the automatic performance device 18, are assigned to the ninth part as the part with the lowest priority, and the ninth part is set to the MIDI channel "1". , The number of sound channels is "3", the tone number is "12",
The number of reserves is set to "3" (the number of reserves is reduced in order to increase the number of musical tone generating channels to be truncated) (FIG. 3).
(B)).

Further, the MIDI channel 10 of the keyboard device 22 is assigned to the first part having the highest priority (FIG. 3B).

Thus, the minus one part is assigned to the ninth part having the lowest priority, and the MIDI channel 10 of the keyboard device 22 is set to the first part having the highest priority. become.

Note that, as described above, minus one.
Since the number of reserves of the ninth part, which is the part, is reduced to "3", the number of truncated musical tone generating channels increases, and the number of musical tone generating channels of the high-priority part can be increased. Musically excellent.

Although the timbre number of the ninth part, which is the minus one part, is the timbre number "12" of the selected first part, it is possible to change the timbre number to another timbre. Good. For example, when the part of the tone of the piano is selected as the minus one part, the performance on the keyboard device 22 is directly performed by the tone of the piano, and the performance of the minus one part by the automatic performance device 18 is performed by the tone of the guitar. By doing so, the performance of the minus one part by the automatic performance device 18 becomes easy to hear, which is extremely effective when the performance by the keyboard device 22 is referred to.

Such a change in the number of reserves and a change in timbre can be performed by a known technique, and therefore detailed description is omitted. May be set, or may be stored in the ROM 14 in advance. For example, the reserve number to be reduced at a certain reserve number may be stored, or when a part of a certain timbre is selected as a minus one part, which timbre should be changed may be stored.

When the process of step S204 is completed, the process proceeds to step S206, and the volume parameter stored in the minus one-part volume parameter memory area 16d of the RAM 16 is changed by operating the minus one-part volume operator 36. The content is transferred to the minus one part having the lowest priority, and the storage content of the volume parameter is updated. FIG. 3B shows a case where the volume level “8” is set in the ninth part, which is the minus one part.

When the processing of step S206 is completed, the minus one event processing routine is completed.

On the other hand, if the decision result in the step S202 is negative (N), that is, if the operation of selecting the minus one off is performed by the minus one operator 34, the process proceeds to a step S208.

In step S208, minus
Change the one part to the original part before it was selected as the minus one part. That is, step S2
The processing reverse to the processing of step 04 is performed. Therefore, by this processing, the MIDI channel and various tone control parameters set for each part return to the state before the minus one-on setting. When the processing in step S208 is completed, the minus one event processing routine ends.

FIG. 4 is a flowchart showing a musical sound generation routine by the automatic performance device. The tone generation routine by the automatic performance device starts its operation in response to a MIDI event A generated by inputting a MIDI signal A output from the automatic performance device 18.

First, when this MIDI event A is detected, in step S402, this MIDI signal A
Is note-on information or note-off information. If the determination result in step S402 is affirmative, that is, if the MIDI signal A is note-on information or note-off information, step S40
Proceed to 4.

In step S404, it is determined whether or not the operation of the minus one operator 34 is set to minus one on. That is, the minus one memory area 16b of the RAM 16 is read and compared with the minus one on data to determine whether the current setting is minus one on or minus one on.
Detect if it is not on. If the determination result in step S404 is affirmative, that is, if the current setting is minus one-on, the process proceeds to step S406.

In step S406, the MIDI of the note-on information or note-off information of the MIDI signal A is performed.
The channel is set to minus /
It is determined whether or not it corresponds to the MIDI channel of the part selected as the one part. That is,
Read the part memory area 16a of the RAM 16,
The MIDI channel of the MIDI signal A is compared with the MIDI channel set to the part selected as the minus one part by the part selection operator 32, and the note-on information or the note-off information of the MIDI signal A is Minus /
It is detected whether the part corresponds to the part selected as the one part.

The result of the determination in step S406 is affirmative, that is, the note-on information or note-off information of the MIDI signal A is selected as the minus one part by the part selection operator 32 for performing the minus one. If it corresponds to the MIDI channel of the part, the process proceeds to step S408.

In step S408, the tone generator 28 generates / stops a tone in a part in which the MIDI channel of the part selected as the minus one part is set, based on a known technique. Tones or silences musical tones via. At this time, regarding the volume parameter, since the contents stored in the minus one part volume parameter memory area 16d of the RAM 16 are transferred (minus one part in FIG. 2).
Step S2 in the flowchart of the event processing routine
06), tone generation / stop is performed according to the volume level set by operating the minus one part volume operator 36. Therefore, according to the volume level arbitrarily set by operating the minus one part volume control 36,
Automatic performance of minus one part can be performed.

At this time, the minus one part is assigned to the part having the lowest priority as described above, and the number of musical tone generating channels to be truncated is increased. Keyboard device 2
The function as a reference for the performance of No. 2 is not substantially impaired.

On the other hand, the parts of the keyboard device 22 are assigned to parts having a higher priority than the minus one part, so that the number of truncated sound channels is reduced, and the performer can perform satisfactorily.

When the processing of step S408 is completed, the tone generation routine by this automatic performance device is completed.

On the other hand, the result of the determination in step S406 is negative, that is, the note-on information or note-off information of the MIDI signal A is changed to the MIDI corresponding to the part selected as the minus one part by the part selection operator 32. If it is not a channel, step S410
Proceed to.

In step S410, the tone generator 28 generates a MIDI signal A based on a known technique.
Based on the channel, a musical tone is generated / stopped in a part corresponding to the MIDI channel, and a tone is generated or muted through the audio device 30. In addition, minus
Even when one-on is set, the volume level of the part other than the part selected as the minus one part by the part selection operator 32 is controlled by the minus one-part volume operator 36. It will not be done.

If the result of the determination in step S404 is negative, that is, if the minus one operator is set to minus one off instead of minus one on, the flow proceeds to step S410. Based on a known technique, the tone generator 28 generates / stops a tone in a part corresponding to the MIDI channel of the MIDI signal A based on the MIDI channel of the MIDI signal A, and sounds or silences the tone through the audio device 30. In this case, since it is set to minus one off, MI
Regardless of the MIDI channel of the DI signal A,
The control of the volume level by the minus one part volume operator 36 is not received.

If the result of the determination in step S402 is negative, that is, if the MIDI signal A is not note-on information or note-off information but other timbre information or system information, the process proceeds to step S412. Based on the MIDI signal A, the MIDI signal A
The processing for the DI signal A is executed.

Next, a tone generation routine by the keyboard device will be described with reference to the flowchart shown in FIG. The musical sound generation routine by the keyboard device starts its operation in response to a MIDI event B generated by inputting a MIDI signal B output based on an operation of the keyboard device 22 by a player. First, when this MIDI event B is detected, in step S502, this M
It is determined whether the IDI signal B is note-on information or note-off information. If the determination in step S502 is positive, that is, if the MIDI signal B is note-on information or note-off information, the process proceeds to step S504.

In step S504, it is determined whether or not the operation of the minus one operator 34 is set to minus one on. That is, the minus one memory area 16b of the RAM 16 is read and compared with the minus one on data to determine whether the current setting is minus one on or minus one on.
Detect if it is not on. If the determination result of step S504 is affirmative, that is, if the current setting is minus one-on, the process proceeds to step S506.

In step S506, the MIDI signal B
Is the highest-priority part in which the MIDI channel of the MIDI signal B is set (minus part shown in FIG. 2).
In step S204 of the flowchart of the one-event processing routine, the MIDI channel of the keyboard device 22 is assigned to the part with the highest priority. ), And by a known technique, the tone generator 2
The tone generator 8 generates / stops the tone, and sounds or silences the tone through the audio device 30.

Therefore, for the part selected as the minus one part by the part selection operator 32, the generation / stop of the musical tone based on the MIDI signal A from the automatic performance device 18 is not performed, and the keyboard by the player is not used. Only the performance by the MIDI signal B from the device 22 is performed, and the minus one performance is achieved. When the processing in step S506 is completed, the musical sound generation routine by this keyboard device is completed.

On the other hand, if the decision result in the step S504 is negative, that is, if the minus one operator is set to minus one off instead of minus one on, the process proceeds to step S508.

In step S 508, the M signal is determined based on the MIDI channel of the MIDI signal B by a known technique.
In the part corresponding to the IDI channel, a musical sound is generated / stopped by the musical sound generation unit 28, and the musical sound is generated or muted through the audio device 30.

If the result of the determination in step S502 is negative, that is, if the MIDI signal B is not note-on information or note-off information but other timbre information or system information, the process proceeds to step S510. Based on the MIDI signal B, the processing is executed by a known technique.

Incidentally, step S in the first embodiment described above.
If the processing content of step 204 is changed and any part is designated as minus one, as shown in FIG. 3C, the MIDI channel 10 of the keyboard device 22 is set to the first highest priority. A part may be assigned, and the other parts may be shifted to parts having lower priority in order.

Next, as a second embodiment according to the present invention,
An embodiment in which the number of musical sound generation channels for each part of the automatic performance device 18 is fixedly set will be described.

The volume setting of the minus one part can be arbitrarily set by the same operation as in the first embodiment. That is, after a predetermined part is selected as a minus one part by operating the part selection operator 32, an arbitrary volume level is selected by operating the minus one part volume operator 36, and the minus one part is selected. Volume parameter memory area 16
The parameter indicating the volume level is stored in d, and the stored content is transferred to minus one part. And
When the automatic performance by the automatic performance device 18 is started, the volume parameter transferred from the minus one-part volume parameter memory area 16d is read based on a known technique. Output, minus one part volume control 36
The tone is emitted at the volume level set by the operation of.

In the case of the second embodiment, the number of tones of the minus one part, which is the part selected by the operation of the part selection operator 32, is reduced to secure the number of sounds to be generated by the keyboard device 22. do it.

For example, as shown in FIG. 6A, in a state where voice assignment is set in advance, the part selection operator 32 selects a part 1 to which four voices are assigned as a minus one part. When the part 1 is played on the keyboard device 22, the number of voices assigned to the part 1 is reduced from four voices, and only the voice 1 is assigned to the part 1 as shown in FIG. All of the remaining three voices may be assigned to the keyboard device 22.

As a result, the part 1 which is referred to for the performance by the keyboard device 22 is often truncated, but can be substantially sufficiently referred to for the performance by the keyboard device 22. On the other hand, the keyboard device 22
As a result, a sufficient number of voices is secured, so that the performer can perform satisfactorily.

The above processing is executed by the voice allocation processing routine shown in FIG.
In this case, when the start of the performance by the automatic performance device 18 is instructed, the automatic performance by the automatic performance device 18 is performed based on a known technique after the flowchart of the voice assignment processing routine shown in FIG. 7 is executed. Will be started.

Next, the flowchart of the voice assignment processing routine shown in FIG. 7 will be described. For ease of understanding, the case where the number of parts is "8" and the number of voices is "8" will be described. The RAM 16 has a PN (part number) register, a VNL (voice number lower) register, a VNH (voice number higher) register, W
Each register of a K (work count) register is provided. The number of each part of the automatic performance device 18 is stored in the PN register, and the first voice number assigned to each part is stored in the VNL register. , VNH register stores the last voice number assigned to each part, and the WK register stores the number of voices for each part in advance.

First, in step S702, "1" is set in the PN register, the VNL register and the VNH register.
Is set to initialize each register. That is, part 1 is set in the PN register, and “1” is set in the VNL register and VNH register of part 1. When step S702 ends, step S702
Proceed to 704.

In step S704, it is determined whether or not the part 1 currently set in the PN register is set as a minus one part by the part selection operator 32. If this judgment is positive,
That is, if the part 1 which is the part currently set in the PN register is set as the minus one part, the process proceeds to step S706.

At step S706, minus one.
When the volume level is not set to "0" by the part volume control 36, the number of voices V (M) when the part 1 which is the part set in the PN register is selected as the minus one part. (For example, FIG.
When setting as shown in (b), set “1”,
“V (M) = 1”. V (M) when each part is set as a minus one part
May be provided, and the table may be referred to. ) Is set in the WK register. When the volume level is set to "0" by the minus one part volume operator 36, "0" is set to the WK register. When the processing in step S706 ends, the process proceeds to step S708.

On the other hand, if the decision result in the step S704 is negative, that is, if the part 1, which is the part set in the PN register, is not set as the minus one part, the process proceeds to a step S710 to set the PN register. The voice number V when the selected part is not selected as the minus one part (for example, “4” is set when setting as shown in FIG. 6A and “V =
4 ". Note that a table indicating V when each part is not set as the minus one part may be provided, and the table may be referred to. ) Is set in the WK register, and the flow advances to step S708.

In step S708, it is determined whether the WK register has been set to "0". If the result of this determination is negative, the operation proceeds to step S712.

In step S712, "VNH = VNL"
+ WK−1 ”and calculates the last voice number assigned to part 1, and then proceeds to step S7.
Proceeding to step S14, the calculation result is stored in the voice assignment table (FIG. 8). Upon completion of the process in the step S714, the process proceeds to a step S716.

On the other hand, if the decision result in the step S708 is negative,
That is, if the WK register has been set to "0", the process jumps to step S716. That is, in this case, since the volume level of the part set in the PN register is "0", there is no need to sound this part. Therefore, no voice is assigned to this part.

In step S716, it is determined whether or not the value set in the PN register is "8". If the determination result is negative, that is, if the value set in the PN register is not more than "8", To step S718,
The N register is incremented by “1”, and the value obtained by adding “1” to the VNH calculated in step S712 is
NL is set, and the loop from step S704 to step S718 is repeated to calculate VNH for each part.

Then, step S70 is performed for each part.
By repeating the loop from 4 to step S718 and calculating VNHs for all eight parts, the value of the PN register becomes “8”.
At this time, the result of the determination in step S716 is affirmative, and the process proceeds to step S720.

In step S720, the remaining voices are assigned to keyboard device 22, and this routine ends.

FIG. 8 shows a voice assignment table that is set in the above-described routine when a voice is assigned to each part and the keyboard device 22 as shown in FIG. 6B.

As described above, in each of the above embodiments, the volume level of the minus one part can be set arbitrarily. Therefore, if the volume level of the minus one part is set relatively low, the keyboard The user can listen to the minus one part without disturbing the performance of the device 22 and as a reference for the performance of the keyboard device 22.

In each of the above embodiments,
The one-part volume control 36 allows you to
If the volume level of the part is set to “0” and the performance by the keyboard device 22 is not performed, a so-called part mute function can be realized in which the performance of the minus one part can be completely silenced.

Further, in each of the above embodiments, the volume level of the minus one part is raised by the minus one part
If the performance by the second part is not performed, the minus one part can be heard more clearly in relation to other parts, and a so-called part monitor function can be realized. At this time, the volume of the part monitored by the part monitor can be set arbitrarily, so that the volume can be set to the most convenient volume for the player.

In each of the embodiments described above, the minus one performance has been described.
8 to set the volume level of all the parts, the volume parameter indicating the volume level set by operating the all-part volume control 38 is stored in the all-part volume parameter memory area 16d.
The volume of the MIDI channel of the MIDI signal A may be controlled according to the volume parameter of the all-part volume parameter memory area 16d. In such a case, if the volume levels of all parts are set to “0”, it is possible to realize so-called all mute, in which the performances of all parts of the automatic performance device 18 are completely muted. By setting to a predetermined volume level, it is possible to play as background music.

Also, in the second embodiment, similarly to the first embodiment, a table in which the minus one-part volume operator 36 and the setting of the tone color parameter are linked is stored in the ROM 14, and When you change the volume level of the minus one part, the minus one part
The tone of the part may be changed.

It is to be noted that an operator capable of setting such a tone change may be separately provided in the operator section 26.

Further, in each of the embodiments described above, the keyboard device 22 and the automatic performance device 18 are external devices. However, these devices may be built in.
