Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a music information input device suitable for use in automatic performance equipment, etc. By making it possible to specify length), etc., input operations can be performed easily and accurately.

[Prior art]

Conventionally, when inputting pitch information, note length information, etc. to an automatic performance device or the like, a method has been adopted in which the pitch, note length, etc. are specified by pressing keys on a keyboard similar to a typewriter.

However, according to this method, pitch specification keys and note length specification keys are mixed, so
It is difficult for non-skilled users to perform efficient input work because they have to spend time finding the key to press.

[Purpose of invention]

The purpose of this invention is to provide a new music information input device that allows even an unskilled person to perform input operations easily and accurately.

[Structure and action of the device]

The music information input device according to this invention includes: (a) a rotary operator; (b) a detection means for detecting the rotation angle of the rotary operator to generate rotation angle information; and (c) a pitch input operator. (d) a note length input operator; (e) pitch information generating means for converting rotation angle information from the detection means into pitch information and transmitting the pitch information based on the operation of the pitch input operator; (f) note length information generation means for converting the rotation angle information from the detection means into note length information based on the operation of the note length input operator; The apparatus includes display means for displaying pitch information and note length information from the note length information generation means.

According to the configuration of this device, pitch information is generated based on the operation of the rotary operator when the pitch input operator is operated, and pitch information is generated based on the operation of the rotary operator when the note length input operator is operated. Since note length information is generated using a single rotary operator, pitch and note length can be specified using a single rotary operator. Furthermore, since a display means is provided to display pitch information and note length information, accurate information can be entered while confirming the information content.

〔Example〕

FIG. 1 shows a music information input device according to an embodiment of the invention, which includes an operating unit 10, a one-note display unit 12, and a one-measure display unit 14. Further, FIG. 2 shows the operating unit 10 and the display unit 12 in a plan view.

On the panel of the operating unit 10, there are a pitch input enable switch 16 and a note length input enable switch 1.
8, a rest length input enable switch 20, and a write command switch 22, and a rotary operator 24 is provided on the right side of these switches so that it can be rotated intermittently by a click mechanism. The switches 16, 18, and 20 have a mechanism that prevents them from being turned on at the same time (only one of them can be turned on), and the rotary operator 24 changes the pitch when the switch 16 is turned on, and when the switch 18 is turned on. When the switch 20 is turned on, the note length can be specified, and when the switch 20 is turned on, the rest length can be specified. Note that the write command switch 22 is turned on when writing note information generated based on the pitch/note length designation operation or rest information generated based on the rest length designation operation to the data memory. It is something that

The one-note display unit 12 is connected to the circuit in the operating unit 10 via a cable 26, and each time a pitch/note length designation operation is performed, the one-note display unit 12 displays the designated note at the designated pitch on the staff. The specified rest is displayed at a predetermined position on the staff each time a rest length designation operation is performed. For example, the display unit 12 is 50
It can be constructed with a liquid crystal display of approximately 16 x 16 dots. The user confirms the note or rest information by looking at the display unit 12, and after confirming this, turns on the write command switch 22 to write the note or rest information corresponding to the displayed content into the data memory. I can do it.

The one-measure display unit 14 is connected to the circuit within the operating unit 10 via a cable 28, and is designed to display one-measure note/rest information on a staff based on specified operations. There is. By looking at the display unit 14, the user can
You can check the input information for a measure.

FIG. 3 shows the circuit configuration of the above-described music information input device.

The rotation angle detection circuit 30 includes, for example, a rotary encoder and the like, and is configured to detect the rotation angle of the rotary operator 24 and generate rotation angle data AD.

The pitch data generation circuit 32, note length data generation circuit 34, and rest length data 36 are all stored in a ROM.
(read-only memory)
The ON signal “1” from the pitch input enable switch 16, note length input enable switch 18, and rest length input enable switch 20 is set as an enable signal.
When received as EN, circuit 32 receives rotation angle data.
The circuit 34 converts AD into pitch data PD, the circuit 34 converts rotation angle data AD into note length data LD, and the circuit 36 converts rotation angle data AD into rest length data RD.

When inputting musical note information, after turning on the pitch input enabling switch 16, a specific pitch is specified using the rotary operator 24. Since the ON signal "1" of the switch 16 enables the pitch data generation circuit 32, the rotation angle data is output from the same circuit 32.
Pitch data PD is sent out in response to AD and supplied to the memory circuit 38.

The memory circuit 38 receives the ON signal "1" of the switch 16 as the capture command signal W, and stores and holds the captured data at that time in synchronization with the change of this signal W from "1" to "0". It is something. Therefore, the contents of the memory circuit 38 are stored in the rotary operator 2.
4, the note length input enable switch 18 is turned on after specifying the specific pitch. The pitch data PD corresponding to the designated specific pitch is stored and held.

After turning on the switch 18, when the note length is specified with the rotary operator 24, the note length data generation circuit 34
generates note length data LD corresponding to the specified note length. At this time, the OR gate 40 which inputs the signal of each bit of the pitch data PD from the memory circuit 38 generates an output signal "1", and the AND gate 4
2 is conductive. When the note length data LD is generated, the OR gate 44 which receives the signals of each bit of this data LD generates an output signal "1", and this output signal "1" is written via the AND gate 42. The signal is supplied to the control circuit 46.

The pitch data PD from the memory circuit 38 and the note length data LD from the note length data 34 are supplied to the display unit 12, and the display unit 12 accordingly displays the notes as illustrated in FIG.
After checking the display at this time and confirming that it is the desired note information, the user turns the write command switch 2.
Turn on 2.

Based on the ON signal "1" from the switch 22, the write control circuit 46 also controls the switches 16 and 1.
Write command signal WR and write address signal ADS on the condition that the signal from either 8 or 20 and the signal from AND gate 42 are "1".
is generated and supplied to the data memory 48. Also,
The ON signal “1” of the switch 22 is the memory circuit 38
is supplied as a clear signal C, and the stored data is cleared in response.

The data memory 48 is composed of a RAM (random access memory), and is used to generate pitch data PD and note length data from the memory circuit 38 in response to a write command signal WR and a write address signal ADS. The note length data LD from the circuit 34 is written.

To input rest information, turn on the rest length input enable switch 20, then press the rotary operator 2.
4. Specify the desired rest length. Since the ON signal "1" of the switch 20 enables the rest length data generation circuit 36, the rest length data RD is generated from the circuit 36 in accordance with the rotation angle data AD.
Data memory 48 is provided. Further, the OR gate 50 which receives the signals of each bit of the rest length data RD generates an output signal "1" and supplies it to the write control circuit 46.

At this time, the memory circuit 38 is sending out data in which all bits are "0" as pitch data PD.
This pitch data PD and rest length data RD are supplied to the display unit 12. The display unit 12 is
Rests corresponding to the specified rest length are displayed based on the supplied pitch data PD and rest length data RD. After viewing the display at this time and confirming that it is the desired rest information, the user turns on the write command switch 22. Then, in the same way as in the case of note information input described above, the data memory 48 stores pitch data PD of all bits "0" and the specified rest length in accordance with the write command signal WR and the write address signal ADS. Rest length data RD corresponding to is written.

The display unit 14 displays notes and notes based on pitch data PD, note length data LD, and rest length data RD.
It displays rest information for one measure at a time, and when it finishes displaying notes and/or rests for a certain measure, it disappears and displays notes and/or rests for the next measure sequentially from the beginning. It's starting to go well.

By the above-described information input operation, note/rest information for one song can be written into the data memory 48. After such writing processing is completed, by appropriately reading pitch and note length data from the data memory 48, musical tone generation, key press position display,
Displaying musical scores, printing musical scores, etc. can be performed automatically.

In the above embodiment, the pitch specified by the rotary operator,
The note length etc. are displayed on the display, but this is because pitches such as "do", "re", "mi", whole notes, half notes, quarter notes etc. are displayed on the circumference of the rotary control in advance. It may be possible to write musical notes such as, etc., and to align each written portion with a reference position such as a mark or a see-through window, thereby making it possible to input desired pitch or note length information.

In addition, although the note length input enable switch and the rest length input enable switch were provided separately, one note length enable switch was provided, and depending on the ON or OFF operation of this switch, the note length input or rest length input enable switch was provided. It may also be possible to input the rest length.

Furthermore, instead of operating the input enable switch and then operating the rotary operator as in the above embodiment, the pitch information can be input by first specifying the pitch with the rotary operator and then pressing the pitch input enable switch. may be generated. In this case, if the pitch information is written into the data memory at the same time, the write command switch 22, memory circuit 38, etc. can be omitted.

[Effect of idea]

As described above, according to this invention, the pitch, note length, etc. can be specified using one rotary operator, which simplifies the configuration and operation. Furthermore, since the information content related to the specification can be confirmed on the display, incorrect input can be reduced. Therefore, even an unskilled person can perform input operations efficiently.
