Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display means of an electronic musical instrument capable of receiving a MIDI event.

[0002]

2. Description of the Related Art For electronic musical instruments, MIDI (Musica
l Instrument Digital Interface) is used to connect the instruments to each other.
Electronic musical instruments are connected to each other and performance information is transferred in a format based on the MIDI standard. For example, when a musical instrument is played, the performance information is the MID provided in the musical instrument.
It is transmitted from the I terminal according to the MIDI standard. This MI
The DI is a performance of one performer on a stage or the like, and it is possible to obtain performance effects such as ensemble by simultaneously outputting performance sounds from each of a plurality of electronic musical instruments of different models.

As the performance information, for example, in keyboard performance, each action such as playing the keyboard (note on) and releasing the finger from the keyboard (note off) is transmitted as a message. , This is called a MIDI event. The MIDI message is serial data in units of 8 bits and 1 byte, and a status byte consisting of 1 byte indicating the type of message and 0 to 2
It is composed of bytes and data bytes, and the MSB in 1-byte units is the discrimination bit.

In addition, note-on to the MIDI event,
In addition to note-off, information called control change, which is information about various controllers (operators) other than the keyboard and information for adjusting functions, is also considered as a MIDI event. This control change corresponds to control information such as modulation such as vibrato, volume, breath, pan, damper, and pedal.

[0005]

Recently, a technique for synthesizing a musical tone by simulating a sounding mechanism such as a wind instrument or a string instrument, for example, a musical tone synthesizing device to which a physical model is applied has appeared. From control, more delicate tone color control is possible with MIDI. In principle, this physical model sound source is controlled in a manner similar to that of a natural musical instrument, which is symmetrical in modeling. For example, in a physical model sound source that models a wind instrument, a signal corresponding to breath pressure is given to control the pronunciation and timbre change, but the response of the physical model sound source to this breath pressure corresponding signal is very delicate like an actual wind instrument. . Therefore, MI
It becomes necessary to display the state of various control signals given to the sound source by DI in some form.

Conventionally, a display device is provided in an electronic musical instrument capable of receiving a MIDI event, and the received MIDI data is displayed on this display device. However, in a sound source that controls pronunciation by performing control similar to that of a natural musical instrument as described above, a breath controller, a foot pedal, or other operator is used for controlling sound production instead of the keyboard as a performance operator. However, these delicate operations become the decisive factor in the quality of performance. In addition, it is becoming difficult to know what kind of controls will be used for playing. Therefore, there is a problem in that simply displaying the received MIDI data and its value one by one as in the conventional case does not help the performance.

Therefore, an object of the present invention is to provide an electronic musical instrument capable of displaying a received MIDI event in an easy-to-understand display suitable for playing.

[0008]

In order to achieve the above object, the electronic musical instrument of the present invention comprises a receiving means for receiving a MIDI event, and a designating means for designating the type of the MIDI event received by the receiving means. A display means for detecting the MIDI event of the type designated by the designating means and displaying the data value contained therein is provided.

The electronic musical instrument of the present invention further comprises a receiving means for receiving a MIDI event, a designating means for designating a type of the MIDI event received by the receiving means, and a MIDI event of the type designated by the designating means. Display means for detecting and displaying a data value contained therein, and a display mode when the data value is detected as a predetermined value and a display mode when not detected as the predetermined value It was made to be different.

[0010]

According to the present invention, the event to be displayed on the display means can be freely selected and displayed.
You can easily adjust the controller (operator), grasp the characteristics, and check the performance status. In particular, regarding adjustment of operators and grasp of characteristics, there are individual differences in lip control of wind instrument type operators, but by setting a predetermined value that makes the display mode different to zero point, the zero point is grasped and adjusted. Will be easier to do.

1 is a block diagram of an embodiment of an electronic musical instrument of the present invention. In this figure, a CPU (central processing unit) 1
Is connected to the bus line 8 and is connected to the ROM (Read Onl
y Memory) 2 takes in data from the bus line 8 based on the CPU program stored in the memory 2, and when the taken-in data is, for example, MIDI event data, the data is sent to the display unit 6, for example. To be displayed. The ROM 2 stores a CPU program and preset tones, and a RAM (Random Acces
s Memory) 3 is used as an area for tone color data stored by the user and a work area for the CPU.

Further, a MIDI interface (I /
F) 4 is an interface that connects the CPU 1 and the MIDI device, receives the MIDI message, and sends the received MIDI message to the bus line 8. The panel operator 5 is an operator for setting a tone color parameter or the like, and is set while watching the parameter displayed on the display unit 6. The display unit 6 is the CPU 1
Under the control of, the parameters are displayed and the types and data of MIDI events are displayed. The musical sound generating section 7 generates a musical sound based on the tone generation data and the tone color data sent via the bus line 8 and outputs it to a sound system (not shown).

The musical tone generated at this time is the ROM 2
The tone is generated by a preset tone color selected from a plurality of tone colors stored in, or a tone color saved by the user in the RAM 3. In addition, the musical tone generator 7
Is a sound source such as a waveform memory sound source, an FM sound source, a harmonic synthesis sound source, etc., and is a sound source capable of selectively generating a waveform of a tone color designated by the musical tone generating unit itself.

Next, an example of a display mode of the display unit 6 according to the present invention is shown in FIG. 2A. This display mode is a display in a normal playing state, for example, a voice (VOICE) mode is set. ing. Further, the breath controller (BREATH) is assigned to the operator 1 (CNT1), and the pedal (PEDAL) is assigned to the operator 2 (CNT2). Function keys F1 to F6 are provided below the operation unit 6. The function keys F1 and F2 are keys for shifting to a mode for changing the controllers assigned to CNT1 and CNT2, respectively, and the function key F3 is The function key F4 is a key for shifting to the edit mode (EDIT), the function key F4 is for shifting to the MIDI monitor mode (MONI), and the function key F5 is a key for shifting to the utility mode (UTLTY).

The utility mode is a mode for setting data save / load, MIDI receiving channel and the like. In the case where the VOICE number is displayed as shown in FIG.
The tone color of "ANO" is set. The VOICE number can be set to any VOICE number by operating the dial 12 or the + 1 / -1 key 13 to select any timbre. And
When editing the selected VOICE, the F3 key may be operated to enter the edit mode. The EXIT key 11 is a key for returning to the original mode, and the cursor key 14
Is a key for moving the cursor displayed on the screen.

FIG. 3 shows a screen in which the F4 key is operated to enter the MIDI monitor mode. In this screen, the display on the left side of the first line is the name of the screen, the display on the right side is the currently selected Voice name, and the left side of the third line is the arbitrarily specified control number. When the number event is received, the received data value (“95” in FIG. 3) is displayed. On the right side of the third line, the value of Main Volume is displayed in the range of 0 to 127. Modulation Wheel value 0 to 1 on the left side of the 4th row
It is displayed in the range of 27, and the value of PiTch Bend is -6 on the right side.
Displayed between 4 and 63. Breath C on the left side of the 5th line
The value of ontroller is displayed in the range of 0 to 127, and the value of After Touch is displayed in the range of 0 to 127 on the right side. 6
The value of FootController is displayed in the range of 0 to 127 on the left side of the line, and the note number and velocity of the Note information of the latest key-on are displayed on the right side.

Note that the note number is displayed in the range of C2 to G8, and the velocity is displayed in the range of 1 to 127. Further, the function line display screen is assigned to the bottom line as described above. Here, "024", "0", and "MO"
"NI" is displayed surrounded by a frame, which means that the display is different from the other displays, and is, for example, a white reverse display. The difference in the display of the "024" portion indicates that an arbitrary control number can be set as described above. The control numbers that can be set and the function names assigned to the numbers are shown in FIG. For example, “002” indicates a breath controller (Breath), and “007”
Indicates a main volume.

Therefore, when the function allocation is set to a number defined by the MIDI standard, the function name is displayed instead of the control number "024".
For example, if "002" is set as the control number, "Breath Cn
"t" will be displayed. By the way, what is displayed here is an event message called "control change" in the MIDI standard, and this event message indicates that it is a control change event. The event message is a 3-byte data consisting of a status byte to which a MIDI channel number is added and a data byte (a value of 128 steps from 0 to 127).

The setting of this control number is
The cursor key 14 is used to move the cursor, and then the dial key 12 and the + 1 / -1 key 13 are used to set a predetermined value. The control number "01
2 "to" 063 "are not assigned, and the user can assign any controller. Therefore, the control number "024" shown in the figure corresponds to the controller assigned by the user.

The Pitch Bend data values are displayed differently because the Pitch Bend data values that can be set from plus to minus are
Because it is set to the zero point. That is, the zero point can be easily recognized. This Pitch
Bend consists of 1 byte of status and 3 bytes of signed data of 2 bytes. Also, in the lower row, "MON
The different display of "I" indicates that the display mode is the MIDI monitor mode. In addition, note events are basically composed of 3 bytes consisting of 1 byte for status, 1 byte for key code, and 1 byte for velocity, but the key-on event when velocity is 0 is treated as key-off, so this is not displayed. May be.

The display of the data value is not limited to the numerical value display, but may be a graph or the like. Also, the number of setting frames for control numbers that can be set arbitrarily is set to one, and only one control change message can be set. However, if the number of setting frames is two or more, there are multiple control change messages that can be set arbitrarily. Good. Further, as a display mode, a specific monitor display may be enlarged so that the received value can be easily seen even if the performer is far away.

Next, the operation of the electronic musical instrument of the present invention will be described with reference to the flowchart. FIG. 5 is a flow chart of the main program of the CPU 1. When this flow chart is started, first, in step S100, initialization processing of registers and the like is performed and then in step S110.
At, the control event detection process of the control provided in the electronic musical instrument body is performed. Further, step S12
0, MIDI event processing is performed, but here, M in the set MIDI reception channel is set.
Only IDI events are accepted. In many cases, the received MIDI events are sequentially stored in the reception buffer on the RAM, and then read out in a first-come-first-served manner and the corresponding processing is performed. Then, in step S130, a mode management process corresponding to the operation of the function key is performed, and when any one of the function keys is operated, the mode corresponding to the function key operated in step S140, that is, VOICE (normal) Select mode, CNT1 / CNT2 allocation change mode, EDIT mode, MIDI monitor (MONI) mode, utility (UTLTY) mode.

If the set mode is the VOICE (normal) selection mode, the tone color selection processing is performed in step S150, and the set mode is CNT1 / CNT2.
In the case of the allocation change mode, the controller setting process is performed in step S160, and the set mode is ED.
In the IT mode, a tone color edit process is performed in step S170. Furthermore, the set mode is M
In the case of the IDI monitor (MONI) mode, step S18
At 0, the MIDI monitoring process of the receiving channel is performed, and if the set mode is the utility (UTLTY) mode, the utility process such as setting of the receiving channel is performed at step S190.

When these processes are performed, step S2
In step 00, musical tone generation processing is performed according to the received MIDI event, and in step S210, other processing is performed, and the processing returns to step S110. Then, steps S110 to S210
However, all musical tones are generated according to the received MIDI event. However, it is also possible to connect a keyboard and generate a musical sound based on the operation of the keyboard.

Next, a flow chart of the MIDI monitor process is shown in FIGS. 6 and 7. When this flowchart starts, in step S300, the DIAL key 12, +
It is detected whether or not there is an operation event of the 1 / -1 key 13. If it is detected that there is an operation event, the input value input in step S310 is set as the MO on the RAM3.
The received control change number is stored by accumulating in the NIT NO area. Then, step S30
Similar to the case where it is detected that there is no operation event at 0, the process proceeds to step S320, and it is detected whether the data accumulated in the MONIT NO area is "000". By the way, the control number is "000" to "1" as shown in FIG.
It is set within the range of 19 ", and in particular, since the control number" 000 "is assigned the function of turning off the monitor function," 000 "is detected here.

If it is detected in step S300 that it is not "000", the process proceeds to step S330 and is shown in FIG.
See the MONIT NO list. When it is detected in step S340 that the display character is assigned by referring to the MONIT NO list, the display character string corresponding to MONIT NO is displayed on the display screen in step S350. If "000" is detected in step S320, the monitor function OFF is designated as described above.
At 370, MONITOR OFF is displayed on the display screen. Further, if it is detected in step S340 that the display character is not assigned by referring to the MONIT NO list, the value of MONIT NO is numerically displayed on the display screen in step S360. Then, in step S375, the MIDI data in the receive buffer of the RAM is sequentially read from the first-come-first-served basis.

Thereafter, the read MIDI reception data is discriminated and the corresponding processing is performed. First, step S380.
MIDI of control number corresponding to MONIT NO
Whether or not an event is received is detected. If it is detected that the event data value is received in step S
Displayed on the display screen at 390. Then, as in the case where it is not detected in step S380 that the MIDI event of the control number corresponding to MONIT NO is received, the process proceeds to step S400.
Of the MIDI event is detected, and if it is detected that the MIDI event is received, the received event data is displayed on the display screen in step S410, and similarly to the case where it is not detected that the received event data is received in step S420.
Proceed to. Then, it is detected whether or not the MIDI event of the Breath Controller is received, and when it is detected that the MIDI event is received, the received event data is set in step S43.
At 0, it is displayed on the display screen.

Then, similarly to the case where the reception event data is not detected as being received, the process proceeds to step S440, it is detected whether or not the MIDI event of the Foot Controller is received, and if it is detected as being received, the reception thereof is performed. As in the case where the event data is displayed on the display screen in step S450 and is not detected as being received, the process proceeds to step S460, and MIDI of Main Volume is set.
Whether or not an event has been received is detected, and if it is detected that the event has been received, the received event data is displayed on the display screen in step S470, and similarly to the case where it is not detected that the event has been received, step S480 shown in FIG.
Then, it is detected whether or not a MIDI event of Pitch Bend is received. In this case, if it is detected that the received event data is “0”, it is determined in step S
When it is further detected in 490 and is not “0”, the event data value received in step S500 is displayed on the display screen in a normal display mode.

If the received event data is detected as "0" in step S490, a white "0" is displayed on the display screen in step S490 so that the zero point can be easily distinguished.
It is displayed at 510. And Pitch Be
As in the case where it is not detected that the nd MIDI event has been received, the process proceeds to step S520, and M of After Touch
Whether or not the IDI event has been detected is detected. If it is detected that the IDI event has been received, the received event data is displayed on the display screen in step S530, and the process proceeds to step S540 as in the case where it is not detected that the event has been received. It is detected whether or not the MIDI event has been received. If it is detected that the MIDI event has been received, the Key Code and velocity values are displayed on the display screen in step S550, and the same return is made as if no reception was detected. It

As described above, when the display mode of the MIDI monitor is set, the Modulation Wheel, Breath Controller, and Foot C in the MIDI reception channel set are set.
When the data value of the controller such as ontroller or Main Volume is received, that data value will be displayed, so the control data of the current value will be displayed, and the control data and the musical sound You can see the correlation and the characteristics of the connected instrument. Therefore, it becomes possible to understand how to control the musical instrument to obtain a desired musical sound.

Since the operation element 1 (CNT1) and the operation element (CNT2) act on musical tones differently depending on the timbre, it is advisable to assign controllers to the respective timbres. In the case of a physical sound source model, the controller is supposed to be able to output a continuous value such as a breath pressure or an impact sensor specific to modeling. For example, in the case of a wind instrument model, the breath pressure corresponding signal (Brea
th Controller) is preferably assigned.

[0032]

Since the present invention is configured as described above, it is possible to freely select and display an event to be displayed on the display means, so that the adjustment work of the controller (operator) and the characteristic You can easily check the grasp and performance status. In particular, regarding adjustment of operators and grasp of characteristics, there are individual differences in lip control of wind instrument type operators, but by setting a predetermined value that makes the display mode different to zero point, the zero point is grasped and adjusted. Will be easier to do.
