Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic musical instrument operating device for informing a player of various states of an electronic musical instrument.

[0002]

2. Description of the Related Art In a conventional electronic musical instrument, for example, when a performer operates a tone color switch on an operation panel to change a tone color, a number assigned to a tone color newly selected by the changing operation (hereinafter, referred to as "tone color"). "Number".) Is displayed. The correspondence between the tone color number and the tone color can be arbitrarily determined for each manufacturer and each model.

On the other hand, a recent electronic musical instrument is generally equipped with a MIDI interface in order to send and receive performance data to and from an external device. In the electronic musical instrument provided with such a MIDI interface, the tone color is changed not only when the tone color switch on the operation panel is operated but also when the program change message in the MIDI message is received, and the tone color number is displayed on the display. Is displayed. According to the MIDI standard, it is stipulated that a tone number is transmitted and received by a program change message,
The correspondence between timbres and timbre numbers is not specified.

Therefore, in the conventional electronic musical instrument, the correspondence between the timbre and the timbre number is appropriately determined by each maker, and the timbre number generated by operating the operation panel and the timbre number transmitted / received by MIDI data have the same meaning. Used in.
Therefore, the display of the tone color number associated with the tone color change does not distinguish between the change from the operation panel and the MIDI data, and the same tone color number is displayed for the same tone color. ing.

[0005]

By the way, in recent years, in order to make performance data universal, GM (G
The general MIDI standard is being adopted. According to the GM standard, the correspondence between the tone color number and the tone color type included in the program change message is uniquely determined. Incidentally, according to the GM standard, in addition to the timbre, for example, the correspondence between the control number included in the control change message and the control target is uniquely determined, but in the following, for simplicity of explanation, the correspondence is limited to the timbre. Explain. By adopting the GM standard, the compatibility of performance data is improved, and the performance data can be distributed more smoothly.

When constructing an electronic musical instrument conforming to the GM standard, for example, the correspondence between 128 kinds of timbre numbers and timbres has already been defined. Therefore, when the timbre is changed by the program change message, the change is made. It is conceivable to configure such that the designated tone color numbers are displayed on the display.

On the other hand, in the conventional electronic musical instrument, on the operation panel, timbre switches having timbre names corresponding to several tens of timbres which are frequently used are arranged, for example, in a matrix, and the timbre is selected with one touch. Often configured to be able to. When a tone color is selected using such a tone color switch, the MIDI standard tone color number assigned to the tone color switch can be displayed in response to the depression of the tone color switch.

However, since the timbre switch having timbre names corresponding to several tens of timbres which are frequently used and the timbre number of the MIDI standard have no relation to each other, the timbre Even if a MIDI standard tone color number is displayed when the switch is pressed, the performer cannot immediately recognize which tone color has been selected. For example, when trying to select a guitar tone, whether the tone number displayed when the tone switch is pressed is certainly the tone number that indicates the tone of the guitar, or the tone switch in the vicinity is pressed by mistake. It is not possible to distinguish whether or not the tone color number is displayed along with.

On the other hand, it is possible to display the numbers (for example, the order in which the tone color switches are arranged) related to the arrangement of the tone color switches as the tone color numbers. In this case, the numbers are the same as the MIDI standard tone color numbers. Is indistinguishable and causes confusion.

Each key of the keyboard device 16 is provided with a key switch that opens and closes in conjunction with key depression or key release, and a signal indicating ON / OFF of the key switch is sent to the keyboard interface circuit 15.

The keyboard interface circuit 15 controls transmission / reception of data between the keyboard device 16 and the CPU 10. That is, the keyboard interface circuit 15 sends a scan signal to the keyboard device 16 and inputs a signal indicating the ON / OFF state of each key switch returned from the keyboard device 16 in response to the scan signal. Then, from this signal, key data in which ON / OFF of each key switch is associated with 1 bit is generated and sent to the CPU 10. This key data is stored in the RAM 12 under the control of the CPU 10 and is used to determine the presence / absence of a keyboard event (details will be described later).

The automatic performance data memory 17 is, for example, RO
It is composed of M. The automatic performance data memory 17 stores automatic performance data corresponding to a plurality of rhythms. The automatic performance data is composed of three types of data for generating three part sounds such as chord, bass and drum. The automatic performance data of each part is created in the same format as MIDI data, for example, and includes step time data for instructing sounding timing. The automatic performance data stored in the automatic performance data memory 17 is converted into a format that can be processed by the sound source 19 in the automatic performance processing described later and is sent to the sound source 19.

The automatic performance data may be stored in a part of the RAM 12 instead of the automatic performance data memory 17. In this case, for example, a floppy disk device (or ROM card controller) is connected to the system bus 30, and a floppy disk (or R
The automatic performance data is stored in an OM card), and the automatic performance data is stored in a RAM 12 from a floppy disk (or a ROM card inserted in a ROM card control device) installed in a floppy disk device when the electronic musical instrument is powered on.

The sound source 19 is composed of, for example, a plurality of oscillators. Then, 1 is set for each tone generation channel that is defined to generate a tone corresponding to a key depression of the keyboard device 16 and a tone corresponding to each part of the automatic performance.
One to several oscillators are assigned. The oscillator, to which the sound is assigned, reads the waveform data stored in the waveform memory 18 in a time division manner and adds an envelope to the waveform data to generate a digital musical tone signal. This sound source 1
The digital tone signal generated in 9 is sent to the D / A converter 20.

The D / A converter 20 converts the input digital musical tone signal into an analog musical tone signal and outputs it. The analog tone signal output by the D / A converter 20 is sent to the amplifier 21. The amplifier 21 amplifies the input analog musical tone signal with a predetermined amplification factor and outputs it. The analog tone signal output by the amplifier 21 is sent to the speaker 22. The speaker 22 is a well-known one that converts an analog musical tone signal as an electric signal into an acoustic signal. By the speaker 22, a musical sound according to the operation of the keyboard device 16 or a musical sound according to the automatic performance data read from the automatic performance data memory 17 is emitted.

Next, the operation of the embodiment of the electronic musical instrument according to the present invention having the above-mentioned structure will be described with reference to the flow charts shown in FIGS.

FIG. 3 is a flow chart showing the main routine of this electronic musical instrument, which is started by turning on the power.
That is, when the power is turned on, first, initialization processing is performed (step S10).

In this initialization processing, the internal state of the CPU 10 is set to the initial state, and the initial values are set to the registers, counters, flags, etc. defined in the RAM 12. Further, in this initialization process, a process of sending predetermined data to the sound source 19 and preventing an unnecessary sound from being generated when the power is turned on is also performed. When this initialization processing is completed, switch event processing is then performed (step S11). Details of this switch event processing are shown in FIG.
Is shown in the flowchart.

In the switch event process, first, a panel scan is performed (step S20). That is, CPU
As described above, reference numeral 10 denotes panel data (hereinafter, referred to as “panel data”) from the operation panel 14 via the panel interface circuit 13.
It is called "new panel data". ) Is read. Next, the panel data that has been read last time and already stored in the RAM 12 (hereinafter referred to as "old panel data") is compared with the new panel data to create a panel event map in which different bits are turned on.

When the panel scan processing, that is, the creation of the panel event map is completed in step S20, it is then checked whether or not there is a switch event (step S21). This is done by referring to the panel event map above. That is, if there is even one bit that is turned on in the panel event map, it is determined that there is a switch event.

If it is determined that there is no switch event, the switch process of step S22 is skipped and the process branches to step S23. On the other hand, when it is determined that there is a switch event, the switch process is performed on the switch having the event (step S2).
2). The details of this switch processing are shown in the flowchart of FIG.

In this switch processing, it is first checked whether or not there is an on event of the tone color switch 140 (step S30). This is done by checking whether the bit corresponding to any one of the tone color switches 140 in the event map is turned on and whether the corresponding bit in the new panel data is turned on. If it is determined that there is an on event of any of the tone color switches 140, the tone color switch process of step S31 and the subsequent steps is performed.

That is, first, the tone color switch flag is set (step S31). Here, the tone color switch flag is a flag provided in the RAM 12, and is a flag for storing that the display based on the operation of one of the tone color switches 140 is being performed. At this time, a flag for storing that the display based on the tone color change request from other parts is stored (for example, a sound memory switch flag based on the tone color change request from the sound memory switch 142, a tone color change request by a MIDI message Based MIDI flags, etc.) are all cleared. This tone color switch flag, sound memory switch flag, M
The IDI flag and the like are referred to when returning to the original timbre display after other information is temporarily displayed on the display 143 by a demonstration performance or the like.

Then, the switch number of the operated switch in the tone color switch 140 is set in the switch number storage buffer provided in the RAM 12 (step S).
32). The contents of the switch number storage buffer are the contents of the LED display data setting process (step S3) described below.
3) and tone color change processing (step S34). It is also referred to when the tone color is restored to the original tone color after the tone color is temporarily changed by, for example, a demonstration performance.

Next, the LED display data is set (step S33). This processing differs depending on whether the electronic musical instrument is in the first mode or the second mode. Whether the vehicle is in the first mode or the second mode is determined by the mode flag updated in response to the event of the GM changeover switch 141 in "other processing" (step S35) described later. The mode flag is a flag provided in the RAM 12 and stores whether the electronic musical instrument is in the first mode or the second mode.

When the electronic musical instrument is in the first mode, the switch number table in the program memory 11 is referred to by using the switch number of the operated switch in the tone color switch 140 as a keyword, and the display data corresponding to the switch number is displayed. Is read. The read display data is set in the display buffer provided in the RAM 12. For example, in the example described above, when the SAX switch of the tone color switch 140 is pressed,
The data "A06" is set in the display buffer.

On the other hand, when the electronic musical instrument is in the second mode, for example, the first switch 2 of the tone color switches 140,
When the No. 3 switch and the No. 3 switch are pressed in sequence,
Numerical data "123" is set in the display buffer. The contents of this display buffer are referred to in the LED processing (step S23) of the switch event processing routine described later.

Next, a tone color changing process is performed (step S34). This process also differs depending on whether the electronic musical instrument is in the first mode or the second mode, as in the above. That is, when the electronic musical instrument is in the first mode, the switch number table in the program memory 11 is referenced with the switch number of the operated switch in the tone color switch 140 as a keyword, and the tone color corresponding to the switch number is selected. The number is read. This read tone color number is set in the tone color number storage buffer provided in the RAM 12.

On the other hand, when the electronic musical instrument is in the second mode, for example, the first switch 2 in the tone color switch 140,
When the No. 3 switch and the No. 3 switch are pressed in sequence,
The data "123" is set as the tone color number in the tone color number storage buffer. The contents of the tone color number storage buffer are stored in the keyboard event process (step S1) described later.
2) Referenced when a musical tone is generated in the automatic performance process (step S14). More specifically, the waveform data to be read from the waveform memory 18 is determined based on the tone color number stored in this tone color number storage buffer.
After that, the process returns from this switch processing routine and returns to the switch event processing routine.

On the other hand, if it is determined in step S30 that the tone color switch 140 is not an on event, "other processing" is performed (step S35). This “other processing” includes processing for events of various switches provided on the operation panel 14.

For example, in this "other processing", it is judged that there is an event of the GM changeover switch 141 by checking whether the bit corresponding to the GM changeover switch 141 in the panel event map is turned on. Then, the mode flag is inverted (details are not shown). As a result, the GM changeover switch 14
Each time 1 is pressed, the first mode and the second mode are alternately repeated.

In this "other processing", for example, processing for an event of the sound memory switch 142 is performed (details are not shown). The process for the sound memory switch 142 is almost the same as the process for the event of the tone color switch 140 described above, and therefore will be briefly described below. That is, whether or not there is an on event of the sound memory switch 142 is checked by the same method as described above, and the sound memory switch 14
If it is determined that there is an on event of any one of the switches No. 2 and No. 2, the sound memory switch flag is set, and a flag for storing that the display based on the tone color change request from other parts is stored (for example, , Tone switch 1
A tone color switch flag based on a tone color change request from 40,
MID based on tone color change request by MIDI message
(I flag etc.) are all cleared.

Then, the switch number of the operated switch in the sound memory switch 142 is set in the switch number storage buffer provided in the RAM 12.
Then, the LED display data is set. That is,
Program memory 1 using the switch number of the operated switch in the sound memory switch 142 as a keyword
The switch number table in 1 is referred to, the display data corresponding to the switch number is read out and set in the display buffer provided in the RAM 12. For example, in the example described above, when the second switch of the sound memory switch 142 is pressed, the data "P02" is set in the display buffer.

Next, a tone color changing process is performed. In this tone color changing process, the switch number table in the program memory 11 is referred to by using the switch number of the operated switch in the sound memory switch 142 as a keyword, and the tone color number corresponding to the switch number is read out and provided in the RAM 12. It is set in the stored tone color number storage buffer. The contents of the tone color number storage buffer are referred to when a musical tone is generated in a keyboard event process and an automatic performance process described later. With the above, the process for the event of the sound memory switch 142 is completed.

Further, in this "other processing", an automatic performance start switch, a rhythm selection switch,
Processing for an event such as a volume adjustment switch and a sound effect selection switch is also performed.

Like the tone color switch 140, the rhythm selection switch is made up of a plurality of switches each having a rhythm name and a number, and this is selected according to the mode designated by the GM changeover switch 14. It can be configured to specify the rhythm by any of the numbers. Then, when selecting a rhythm by the rhythm name, the data related to the arrangement position of the rhythm selection switch is displayed, and when designating the rhythm by the rhythm number, a numerical value indicating the rhythm number is displayed. The rhythm number designated by any of the above methods is set in the rhythm number storage buffer provided in the RAM 12 and referred to in the automatic performance process described later. According to such a configuration, similar to the case of the tone color switch 140, the rhythm selection operation can be surely performed, and the operability is improved. When this "other processing" ends, the switch processing routine returns and returns to the switch event processing routine.

In the switch event processing routine, LED processing is then performed (step S23). This L
The ED process is a process of displaying predetermined data on the display 143 of the operation panel 14. In this LED processing, for example, processing of displaying the data set in the display buffer in step S33 of the switch processing routine is performed. This display is realized by sending the display data set in the display buffer to the operation panel 14 via the panel interface circuit 13.

When this LED processing is completed, then vendor wheel processing is performed (step S24). This bender wheel process is a process of changing the pitch of a musical tone being sounded, for example, according to the operation of a bender wheel (not shown) provided on the operation panel 14. This bender wheel process is not directly related to the present invention, and therefore its explanation is omitted. When this vendor wheel process is completed, the process returns from the switch event process routine and returns to the main routine.

In the main routine, keyboard event processing is then performed (step S12). That is, CPU1
As described above, 0 reads the key data (hereinafter referred to as “new key data”) from the keyboard device 16 via the keyboard interface circuit 15. Next, the key data (hereinafter referred to as “key data” previously read and already stored in the RAM 12)
It is called "old key data". ) Is compared with the new key data to create a key event map with different bits turned on. Then, it is checked whether there is a key event by referring to this key event map. This is done by checking for the presence of bits that are turned on in the key event map.

Here, if there is no bit that is turned on in the key event map, it is recognized that there is no key event, and this keyboard processing ends. on the other hand,
If there is more than one bit turned on in the key event map, it is recognized that there was a key event, and it is checked whether the key event is an on event or an off event. This is done by checking if the bit in the new key data corresponding to the on bit in the event map is on.

If it is determined here that there is a key-on event, sound generation processing is performed. That is, the key number of the key related to the key depression, the tone color number set in the tone color number storage buffer at that time, the data indicating the keystroke strength, etc.
Is converted into data in a format that can be interpreted by, for example, waveform address, frequency data, envelope data, filter coefficient, etc., and sent to the sound source 19. As a result, the sound source 19 activates the oscillator corresponding to the sounding channel assigned to the keyboard device 16. As a result, the oscillator reads the waveform data from the waveform memory 18 and adds the envelope to the waveform data to generate a digital tone signal. This digital musical tone signal is converted into an analog musical tone signal by the D / A converter 20 and is amplified by the amplifier 21 and then sent to the speaker 22. As a result, a tone corresponding to a key press is generated from the speaker 22 with a tone color designated by the tone color switch 140, the sound memory switch 142, or the like.

On the other hand, when it is determined that the event is the key-off event, the mute processing is performed. That is, the sounding oscillator corresponding to the key to be released is searched for, and predetermined data is sent to cancel the sound.

When this keyboard event processing is completed, MIDI processing is then carried out (step S13). In this MIDI processing, MIDI data is exchanged with an external device via the MIDI interface circuit 23. The tone color change is also performed by the program change message of the MIDI message. That is,
When the MIDI message of the program change instructing the tone color change is received, the CPU 10 sets the MIDI flag and stores a flag indicating that the display based on the tone color change request from other parts is stored (for example,
(A tone color switch flag based on a tone color change request from the tone color switch 140, a sound memory switch flag based on a tone color change request from the sound memory switch 142, etc.)
Clear all.

The CPU 10 also sets the tone color number included in the MIDI message in the tone color number storage buffer in the RAM 12. As a result, the tone color is changed by the MIDI message as in the case where the tone color switch 140 of the operation panel 14 is operated to change the tone color.
In this case, the tone color number itself is displayed on the display 143. The processing for other MIDI messages is not directly related to the present invention, and thus the description thereof is omitted.

Upon completion of this MIDI processing, next,
Automatic performance processing is performed (step S14). In this automatic performance processing, processing for generating a rhythm performance sound is performed.

The automatic performance process is performed when the electronic musical instrument is set to the automatic performance mode by the automatic performance start switch and the automatic performance data read timing is reached. Whether or not it is the read timing of the automatic performance data is determined by referring to the contents of a counter (not shown) provided separately. When it is determined that it is the read timing, one piece of automatic performance data is read from the automatic performance data memory 17.
Then, the step time value included in the automatic performance data is compared with the time value counted up by a time counter (not shown), and if they match, sounding or mute processing is performed.

That is, if the automatic performance data read from the automatic performance data memory 17 is note-on data, the tone generation processing is performed. In the tone generation processing, for example, waveform addresses, frequency data, envelope data, filter coefficients, etc. are generated based on the automatic performance data read from the automatic performance data memory 17, and are sent to the sound source 19. As a result, the automatic performance sound is generated in the same manner as the sound generation processing for the event of the keyboard device 16.

On the other hand, if the automatic performance data read from the automatic performance data memory 17 is the note-off data, the mute processing is performed. The sound deadening process is a process of sending predetermined data to the sound source 19 to stop the generation of the digital tone signal in the sound source 19 and to mute the sound being sounded.

When the automatic performance data read out from the automatic performance data memory 17 is data for instructing a tone color change, a tone color changing process is performed in the same manner as the tone color changing process in the MIDI process described above ( Detailed explanation is omitted). In addition to the data for instructing note-on, note-off, and tone change, automatic performance data includes
For example, it includes data for instructing volume change, tempo change, etc., but since it is not directly related to the present invention, description thereof will be omitted.

When the automatic performance process is completed, then
"Other processing" is performed (step S15). This "other processing" includes damper processing and the like accompanying depression of a foot pedal (not shown). Then step S11
Then, the same processing is repeated thereafter. Step S1
When an event based on a panel operation or a keyboard operation occurs in the process of repeatedly executing 1 to S14, various functions as an electronic musical instrument are exhibited by performing processing corresponding to the event.

As described above, according to the operating device of the present embodiment, first, the GM changeover switch 141 is used to determine whether the tone color switch 140 is used in the first mode or the second mode. select. When a predetermined switch in the tone color switch 140 is operated in the case where the first mode is designated, a tone color number indicating the tone color assigned to the switch is generated and the tone color number corresponding to the array position is generated. Display data is generated and displayed on the display 143. On the other hand, when the second mode is designated and a predetermined switch in the tone color switch 140 is operated, the numerical value assigned to the switch is used as it is as the tone color number and the display data.

As a result, when the tone color switch 140 is used in the first mode, when each switch of the tone color switch 140 is operated, the data corresponding to the arrangement position of the switch is displayed and the corresponding switch is operated. Since the timbre number is generated, the operator can immediately recognize the correspondence between the operated switch and the information displayed on the display 143. Thereby, erroneous operation can be prevented and the operability is excellent. On the other hand, when the tone color switch 140 is used in the second mode, the numerical value generated by operating the switch is used as it is as the tone color number and the display data, so that the tone color number can be directly input. Therefore, a wide range of tone color numbers can be input, which is excellent in usability.

In the above embodiment, the case where the operating device is applied to the tone color switch 140 has been mainly described.
As described above, the present invention can be similarly applied to the rhythm selection switch, and can also be similarly applied to, for example, a switch for selecting the type of acoustic effect.
