On the front panel of the electronic musical instrument 1, a display 2 for displaying a tone parameter name and its value, an output code corresponding thereto, etc., select keys 7 and 8 for selecting a tone parameter name, and a value of a tone parameter are input. Plus key 3,
Various switches such as a minus key 4, an enter key 5, and an exit key 6 are provided. The keys indicate only those relevant to the present invention. A plurality of tone parameters are stored so as to be selected in a predetermined order, for example. The select key 7 is a switch for selecting the next tone parameter name each time the key is pressed, and automatically selecting the next tone parameter name when the key is kept pressed. The select key 8 is a switch for selecting the previous tone parameter name each time it is pressed, and automatically selecting the next tone parameter name automatically when the key is kept pressed. On the other hand, the plus key 3 is a switch that increases the value of the selected tone parameter by one each time the key is pressed, and automatically increases the value by one when the key is kept pressed. The minus key 4 is a switch that decrements the value of the selected musical tone parameter by one each time the key is pressed, and automatically decreases the value by one when the key is kept pressed. The enter key 5 is a switch for determining the value of a musical tone parameter or outputting the musical tone parameter to an external device in the form of a MIDI code. The exit key 6 is a switch for returning to the beginning of the tone parameter edit mode. Using the various input keys described above, the tone parameter is edited while the tone parameter name and its value are displayed on the display 2, and after editing, the tone parameter value is determined. The MIDI code corresponding to the tone parameter of the determined value is displayed on the display unit 2 and can be connected to an external MIDI device, a host computer, or the like via the MIDI interface 16 or another interface described above.
Output to a network computer, etc. FIG. 2 is a schematic configuration diagram of an example of the internal configuration of the embodiment shown in FIG. The bus line 11 has a CP
U12, RAM 13, ROM 14, input device 15, MI
The DI interface 16, the display 2, the sound source 17, and the like are connected. The display 2 corresponds to the display shown in FIG. Operation information from the input device 15 and MIDI information
The CPU 12 processes the performance information input from an external MIDI device via the interface 16 based on the information stored in the ROM 14 using the RAM 13 for temporary storage, and displays the performance information on the display 2. Display,
The sound source 17 is controlled based on the processed performance information, and the processed performance information is transmitted to the MIDI interface 16.
Output to an external MIDI device via. The MIDI interface 16 is provided with a “MIDI IN” terminal for inputting a MIDI code from an external device and a “MIDI OUT” terminal for outputting a MIDI code to the external device. The sound source unit 17 has a built-in DA converter and outputs a musical sound waveform to an external sound system via an audio output terminal. An electronic musical instrument having controls such as a keyboard, pitch bend, modulation wheel, sustain, and foot volume is connected to a MIDI input terminal as an external device on the input side, but is used as an input device 15 of the electronic musical instrument 1 itself. In addition to the various keys shown in FIG. 1, the keyboard and the various controls described above may be provided. As an interface with the outside, in addition to the MIDI interface 16, an RS23 for connecting to a host computer is used.
There may be a case where a 2C interface is provided, a modem for connecting to a computer on a network, an Ethernet interface, and an IEEE 1394 network interface for mutually connecting a plurality of multimedia related devices. FIG. 3 is a flowchart of the operation and display state for explaining the operation of the embodiment of the present invention. As an example, a case where the volume of the piano is set while editing the tone of the piano will be described. In step S21, a specific tone parameter name is selected using the select keys 7 and 8 shown in FIG. 1, and the tone parameter name and the current set value are displayed.
For example, a volume (volume) is selected as a tone parameter name. In S22, the value of the tone parameter is determined using the plus key 3 and the minus key 4. Until the decision, the tone parameter name and the value being edited are displayed.
For example, assuming that the first set value of the volume value is “50”, the user keeps pressing the plus key 3 to change the value to 51,5.
2, 53, 54,..., And release when the value reaches a value of “100”, for example. Of course, if "50" is acceptable, the process may proceed to the next step S23 without pressing the plus key 3 and the minus key 4. In S23, the value of the tone parameter is determined by pressing the enter key 5, and the tone parameter name and its value, in the above-described example, "volume" and its value "100" are displayed. In order to edit the sound while outputting sound from the sound system, the tone generator 17 is controlled by the value of the tone parameter in the editing buffer in the RAM 13. However, the value of the musical tone parameter set and stored for controlling the tone generator 17 of the electronic musical instrument is changed after the value of the musical tone parameter is determined. In step S24, when the enter key 5 is pressed again, the MIDI code corresponding to the tone parameter having the determined value and output to the external device is, for example, MID
Displayed in hexadecimal notation, which is the normal notation of I code. S
In 25, if the plus key 3 or the minus key 4 is pressed, the process proceeds to S26. If the enter key 5 is pressed again, the process proceeds to S28. If the exit key 6 is pressed, the process proceeds to S21. Reverse processing. In S26, the value of the tone parameter is changed by the plus key 3 and the minus key 4, the MIDI code corresponding to the tone parameter of that value is displayed, and the process proceeds to S27. For example, when the value “100” is changed to 99, 98, 97, the display value of some digits in the MIDI code sequentially changes in accordance with the change of the value. In S27, the musical tone parameters are determined again by pressing the enter key 5 again, the corresponding MIDI code is displayed, and the process proceeds to S28. The value of the musical tone parameter set and stored for controlling the tone generator 17 of the electronic musical instrument is changed again. S28
, The MIDI code is output to an external device. Therefore, after selecting a tone parameter name,
When the enter key 5 is pressed twice, the MIDI code corresponding to the tone parameter is displayed.
When is pressed again, the displayed MIDI code is selectively output. Further, even in the display state of the MIDI code, the tone parameters can be edited with the plus key 3 and the minus key 4. This processing flow can be exited by pressing the exit key 6. As a result, the MI corresponding to the tone parameter
The user can visually check the DI code, understand the correspondence, and learn the MIDI code. When controlling an electronic musical instrument from the sequencer or a personal computer running the software with software,
It is necessary for the user to set musical tone parameters in the electronic musical instrument. In this case, it is possible to know what MIDI code should be transmitted. This is particularly useful when an exclusive message represented by a variable-length MIDI code is used to perform advanced tone settings. Further, only necessary ones of the MIDI codes can be selectively output. In the example above,
The first volume setting value was "50",
Although it is "97" at the time of final determination and output, the MIDI code to be output is only when the value is "97". If you try to do the same by simply stepping on the foot volume as in the past, the MIDI output
The code has the values 51, 52, 53, ... 98, 99, 1
A plurality of MIDI codes corresponding to 00, 99, 98, and 97 are sequentially output. As described above, the conventional MIDI output
A large amount of data including unnecessary data is output to an external device, for example, a MIDI data storage device.
Therefore, in one embodiment of the present invention, the amount of data transmitted through the transmission path, and thus the amount of processing and storage data in the external device can be reduced. The MIDI code corresponding to the volume value "97" can be output after the performance has progressed and the timing of the point at which the volume value is desired to be "97" can be output.
The I data can be efficiently output to the transmission path and the external device. In the above description, the press of the exit key 6 is determined only in step S25. However, if the exit key 6 is pressed in any step, the process immediately returns to the first step S21 in the edit mode. You may do so. The value of the musical tone parameter is increased or decreased by using the plus key 3 and the minus key 4, but a ten key may be used instead. That is, in S22 and S26 of the flowchart, the operation of the plus key 3 and the minus key 4 is replaced with the operation of the numeric keypad, and the value of the musical tone parameter is directly input. Alternatively, a continuously variable operator such as a pitch bend or a modulation wheel may be used. That is, S22, S
At 26, the operation of the plus key 3 and the minus key 4 may be replaced with the operation of a continuously variable operation element. In either case, the value of the musical tone parameter is determined by the enter key 5 in S23, the output code is displayed by the enter key 5 in S24, and the output code is output to the external device by the enter key 5 in S27. To In the above description, an example in which the sound source unit 17 is provided as hardware as shown in FIG. 2 is exemplified. However, the sound source unit 17 is realized by software using a computer having a DA converter and a waveform driver. It may be something. Further, the sound source unit 17 may be provided on an external device via the MIDI interface 16 or the like. Further, the display 2 and the various input switches shown in FIG. 1 may all be virtually present on a personal computer to execute the functions. In this case, the various input switches are displayed on the display screen of the personal computer and operated by a mouse or a keyboard. The output code transmitted to the external device is not limited to the MIDI code. MIDI
The codes are standardized for transmitting performance information as digital information, but in addition to the above, output codes corresponding to external devices to be transmitted and output codes individually adopted in a transmitted network. It may be. The tone parameter setting device of the present invention can be applied to electronic musical instruments, amusement devices such as games and karaoke, various home appliances such as televisions, computer devices represented by personal computers, computer systems, and the like. As is apparent from the above description, the output codes corresponding to the edited musical tone parameters can be visually checked, the correspondence can be clearly understood, and the output codes can be easily remembered. Further, since the determined output code can be selectively output, the amount of data to be output can be reduced, and there is an effect that data can be output efficiently at the timing of output.
