As described above, in this electronic musical instrument, the operation of the part selection operator 32 is used to perform a minus one performance from all the parts whose musical sounds are generated based on the MIDI signal A from the automatic performance device 18. It is possible to arbitrarily select a specific part such as a minus one part or a solo part performing solo performance.

Here, the "part" corresponds to a plurality of timbre musical tones generated simultaneously by the musical tone generator 28, and corresponds to a so-called musical instrument constituent unit in an orchestra. The tone color of the musical tone generated in each part is set separately for each part. Also,
Each part is set to have a one-to-one correspondence with each MIDI channel in the MIDI signal. That is, if the MIDI channel is 16 channels, 16 parts are also set. For example, MI
DI channel “1” corresponds to part “1”, and MID
The I channel “2” and the part “2” are configured to correspond to each other.

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

As a register in the RAM 16, a minus one flag is set for each part of the MIDI signal A output from the automatic performance device 18, and when the part is minus one on, ""1" stands and "0" when the part is minus one off
It is said that

Similarly, user switch flags corresponding to user switch on / off, solo on / off,
A solo flag corresponding to off and an all mute flag corresponding to all mute on / off are set.

Further, in the RAM 16, the stored contents are set for each part by an instrument (tone color) setting of a musical sound generated by the part (an operator (not shown) provided in the operator section 26). Area is set. At the time of tone generation, the ROM is set based on the instrument (tone color) setting status stored in the RAM 16.
The tone color of the musical tone is controlled with reference to the tone color parameters stored in 14.

The operation of the electronic musical instrument having the above structure will be described below.

First, the case of recording minus one on and minus one off in the automatic performance device 18 will be described. When recording minus one on in the automatic performance device 18, first, the automatic It is determined which part of the musical instrument 18 is selected as the minus one part, and the part is selected by the part selection switch 32.
Operate to select. That is, when the part 1 is selected as the minus one part, the part selection switch 32 is operated to select the part 1. At this time, "1" indicating part 1 is displayed on the part display portion 38a.

Next, the vacant track of the automatic performance device 18 is set to the recording mode and the other tracks are set to the reproduction mode, and the automatic performance device 18 is started. Further, the transmission switch 48 is turned on (the LED 50e is turned on), and the setting made by the operating section 26 is set in a state in which it can be transmitted to the automatic musical instrument 18.

Then, while listening to the performance reproduced by the automatic performance device 18, the performance is changed to the part selection switch 3
When the part selected as the minus one part by 2 is played until the performance timing at which the user wants to mute, the minus one switch 40 is pressed (ON operation: LED 50a lights up). In this way, when the minus one is turned on, the control unit 10 instructs the automatic performance device 18 via the MIDI circuit 20 to specify the minus one on for the part selected by the part selection switch 32. Is sent.

In this way, the automatic performance device 18 to which the part information indicating that minus one on has been designated is transmitted from the control unit 10 is transferred to the empty track in the recording mode by the received part information. Minus one
Record as on.

Furthermore, while listening to the performance, at the timing of the performance at which it is desired to cancel the minus one, the minus one switch 40 is pressed again (OFF operation: LED 50
a is off). In this way, when the minus one is turned off, the control unit 10 sends the part information indicating that the minus one on has been released for the part selected by the part selection switch 32, via the MIDI circuit 20. It is transmitted to the automatic performance device 18.

Then, from the control unit 10, minus one
The automatic performance device 18 to which the part information indicating that the on state has been released is transmitted, records the received part information as minus one off on an empty track in the recording mode.

By repeating the above-mentioned operation, it is possible to record minus one on and minus one off at arbitrary performance timings of the vacant track in the recording mode.

Further, by repeating the above operation after selecting another part by the part selection switch 32, it is possible to record minus one on and minus one off for other parts. is there.

Further, in order to change the recorded contents of minus one on and minus one off recorded on the empty track of the automatic performance device 18 by the above operation,
By performing the above operation again with the empty track in the recording mode, the recorded contents of minus one on and minus one off recorded on the empty track are changed to new recorded contents.

Next, with the above operation, minus
Based on the MIDI signal A output from the automatic performance device 18 that records one-on and minus one-off,
A process of generating / stopping a musical sound will be described.

FIG. 2 is a flow chart showing a tone generation routine by the automatic performance device. The musical tone generation routine by the automatic musical instrument is started by a MIDI event A generated by the input of the MIDI signal A output from the automatic musical instrument 18.

First, when the musical tone generation routine by the automatic performance device is started, the minus one process is performed in step S202.

FIG. 3 is a flow chart showing the processing contents of the minus one processing in step S202 as a sub-routine of the musical tone generation routine by the automatic performance device. In this minus one processing routine, it is determined in step S302 whether the MIDI signal A is minus one on. This step S3
The determination result of 02 is affirmative (Y), that is, the MIDI signal A
Is minus one on, step S3
Go to 04.

In step S304, the minus one flag is set to "1" for each part recorded in the MIDI signal A and designated as minus one on. When the processing of step S304 is completed, the minus one processing routine is completed, and the tone generation routine by the automatic performance device is completed.

On the other hand, if the determination result of step S302 is negative (N), the process proceeds to step S306.

In step S306, it is determined whether the MIDI signal A is minus one off. The determination result of step S306 is affirmative, that is,
If the MIDI signal A is minus one off, the process proceeds to step S308.

In step S308, the minus one flag recorded in the MIDI signal A is set to "0" for each part designated as minus one off. When the processing of step S308 is completed, the minus one processing routine is completed and the musical tone generation routine by the automatic performance device is completed.

On the other hand, if the determination result of step S306 is negative, that is, if the MIDI signal A is neither minus one on nor minus one off, the MID
The minus one processing routine is ended without performing the processing for the I signal A, and the process returns to the musical tone generation routine by the automatic performance device. Therefore, when the MIDI signal A is not minus one on or minus one off, when the process of step S202 ends, the process proceeds to step S204.

In step S204, this MID
It is determined whether the I signal A is note-on information or note-off information. If the determination result of step S204 is affirmative, that is, if the MIDI signal A is note-on information or note-off information, step S204
Proceed to 206.

In step S206, it is determined whether or not "1" is set in the minus one flag of any part. The determination result of step S206 is affirmative,
That is, when "1" is set in the minus one flag of any part, the process proceeds to step S208.

In step S208, the MIDI of the note-on information or the note-off information of the MIDI signal A is received.
It is determined whether or not the channel corresponds to the MIDI channel of the part for which "1" is set in the minus one flag.

If the determination result of step S208 is affirmative, that is, if the note-on information or note-off information of the MIDI signal A corresponds to the MIDI channel of the part for which "1" is set in the minus one flag. Ends the tone generation routine by this automatic performance device without generating / stopping the tone.

Therefore, for the part in which the minus one-on is recorded in the MIDI signal A, the automatic performance device 1
This means that the musical sound is not generated / stopped by 8, and the part is muted.

On the other hand, the determination result of step S208 is negative, that is, the note-on information or the note-off information of the MIDI signal A is "1" in the minus one flag.
If it is not the MIDI channel corresponding to the part in which is set, the process proceeds to step S210.

In step S208, the MIDI signal A of the MIDI signal A
Based on the channel, the musical tone is generated / stopped in the part corresponding to the MIDI channel, the musical tone is generated or muted through the audio device 30, and the musical tone generation routine by the automatic musical instrument is finished.

Therefore, even when minus one on is recorded in the MIDI signal A, the MI corresponding to the part for which "1" is set in the minus one flag.
For parts other than the DI channel, musical tones are generated / stopped in the part corresponding to the MIDI channel based on the MIDI channel of the MIDI signal A by the automatic performance device 18.

If the determination result of step S206 is negative, that is, if "1" is not set in the minus one flag of any part and the minus one flag is "0", the step is executed. Proceeding to S210, the musical sound generation unit 28 generates / stops the musical sound in the part corresponding to the MIDI channel based on the MIDI channel of the MIDI signal A based on the known technique, and outputs the musical sound via the audio device 30. Mute. In this case, since minus one on is not recorded in any part (it is set to minus one off), no matter which MIDI channel of MIDI signal A is set to that channel. In the corresponding part, the musical tone is generated / stopped by the automatic performance device 18.

Further, if the determination result of step S204 is negative, that is, if the MIDI signal A is not note-on information or note-off information but other tone color information or system information, the process proceeds to step S212. Based on the MIDI signal A, the MI is transmitted by a known technique.
The processing for the DI signal A is executed.

Next, a musical tone generation routine by the keyboard device will be described with reference to the flow chart shown in FIG. This musical tone generation routine by the keyboard device starts its operation by a MIDI event B generated by the input of the MIDI signal B output based on the operation of the keyboard device 22 by the player. First, when this MIDI event B is detected, this M event is detected in step S402.
It is determined whether the IDI signal B is note-on information or note-off information. If the determination result of step S402 is affirmative, that is, if the MIDI signal B is the note-on information or the note-off information, the process proceeds to step S404.

In step S404, minus one
It is determined whether or not "1" is set in the flag. If the determination result of step S404 is affirmative, that is, if the minus one flag of any part is set to "1", the process proceeds to step S406.

In step S406, the MIDI signal B
Is assigned to the part in which “1” is set in the minus one flag, and the musical sound is generated or stopped by the musical sound generation unit 28 by the known technique, and the musical sound is generated or muted through the audio device 30. To do.

In this case, with respect to the part for which "1" is set in the minus one flag, in step S208 of the musical tone generation routine by the automatic musical instrument, the musical tone is generated / generated based on the MIDI signal A from the automatic musical instrument 18. There is no stop, and the keyboard device 22 by the performer
Only the MIDI signal B from No. 1 will be played, and a minus one performance will be achieved. Step S40
When the process of 6 is finished, the musical tone generation routine by the keyboard device is finished.

On the other hand, if the result of the determination in step S404 is negative, that is, if the minus one flag is not set to "1", the operation proceeds to step S408.

In step S408, M is set based on the MIDI channel of the MIDI signal B by a known technique.
In the part corresponding to the IDI channel, the musical sound generation unit 28 generates / stops a musical sound, and sounds or mutes the musical sound via the acoustic device 30. Therefore, in this case, regardless of which MIDI channel of the MIDI signal B, the musical tone is generated / stopped by the keyboard device 22 in the part corresponding to that channel.

Further, if the determination result of step S402 is negative, that is, if the MIDI signal B is not note-on information or note-off information but other tone color information or system information, the process proceeds to step S410. Based on the MIDI signal B, the processing is executed by a known technique.

The automatic performance device 18 repeats the section of the performance data designated by the minus one on and the minus one off recorded by the above operation to practice the ensemble practice. You may make it improve efficiency.

Further, when the section of the performance data designated by minus one on and minus one off is repeated, the performance timing which goes back about two measures from the performance timing designated by minus one on. It is also possible to repeatedly perform from. In this way, since only the minus one part is not repeatedly played, it becomes easier for the performer to repeatedly perform the minus one part section.

By the same processing as described above, the setting states of the user switch 42, the solo switch 44 and the all mute switch 46 are changed to the automatic performance device 18.
Can be recorded in. When the MIDI signal B is output in accordance with the recorded contents recorded in the automatic performance device 18, the control unit 10 performs the same process as in the case of the minus one process described above, and is recorded in the automatic performance device 18. Musical sounds are generated / stopped based on the recorded contents.

Further, in the above embodiment, the case where the part information recording apparatus according to the present invention is implemented in the sound source apparatus has been described, but it may be implemented in the automatic performance apparatus 18.

Further, in the above embodiment, the keyboard device 22 and the automatic performance device 18 are external devices, but these devices may be incorporated.
