Description

[Detailed description of the invention] [Industrial application field] This invention relates to a music information input device suitable for use in automatic performance equipment, etc., and includes a mark on an input pen for specifying pitch on a pitch input board. The input operation is simplified by providing a length specifying switch.

[Prior art]

Conventionally, when entering music information such as pitch information and note length information into an automatic performance device, etc., you press keys on a keyboard similar to a typewriter to input pitch information, note length (note length or rest length), etc. A method of specifying was adopted.

However, with this method, input operations cannot be performed smoothly unless one is familiar with the correspondence between each key and pitch, note length, etc.
It has been difficult for unskilled people to perform efficient input operations. Furthermore, when performing keyboard operations while looking at a musical score sheet, the viewpoint shifts, making input errors more likely.

[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 consists of (a) an input pen in which a note length designation switch is provided on the pen body so that the pen body can be operated when the pen body is held; (c) a pitch input board for performing a pitch specification operation by specifying a position; and (c) a pitch input board for generating pitch information representing a specified pitch in response to the pitch specification operation using the input pen. information generating means; (d) note length information generating means for generating note length information representing a specified note length in response to a note length specifying operation by the note length specifying switch; and (e) a readable/writable storage device. and (f) generating pitch information and the note length information from the pitch information generating means on the condition that a pitch designation operation is performed using the input pen in conjunction with the note length designation operation using the note length designation switch. Note information including note length information from the means is written into the storage device, and the notes are written on the condition that no pitch specification operation is performed using the input pen in conjunction with note length specification operation using the note length specification switch. and writing means for writing rest information including note length information from the note length information generating means into the storage device.

According to such a configuration, the user can easily and accurately perform input operations with only one hand, such as by stacking musical score sheets on the pitch input board.
That is, by holding the input pen with one hand, specifying the desired pitch on the pitch input board with the input pen, and specifying the desired note length with the note length specification switch, the pitch and note length are indicated. Note information can be written to the storage device. Further, by specifying a desired rest length using a note length specifying switch without performing a pitch specifying operation, rest information representing the rest length can be written into the storage device.

〔Example〕

1 and 2 show a music information input device according to an embodiment of this invention, which includes a pitch input board 10, an input pen 12, and a circuit unit 14. Pitch input board 10 and input pen 12 are connected to an electrical circuit within circuit unit 14 by cables 16 and 18, respectively.

The pitch input board 10 is provided with a musical score sheet arrangement area 22 on its surface for arranging the musical score sheet 20 therein. In this musical score sheet arrangement area 22, a large number of pressure-sensitive elements such as pressure-sensitive switches are distributed in a matrix on a plane, and by electrically scanning these pressure-sensitive elements, an input pen can be input. 12, pen press information and press position information can be obtained.

The input pen 12 is provided with an annular portion 24 through which the thumb is inserted when the pen body is gripped with the right hand, and four note length designation switches 26 each operated with four fingers other than the thumb. , and a shift switch 28 operated by the thumb. This shift switch 28 has a first mode in which the note length specification switch 26 specifies a note length corresponding to a half note, a quarter note, an eighth note, or a sixteenth note, and a first mode that specifies a note length corresponding to a whole note or a 32nd note. This is for appropriately switching between the second mode, which specifies a note length, a note point, etc.

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

The pitch data generation circuit 30 detects information on the position pressed by the input pen 12 from the pitch input board 10 and generates pitch data PD corresponding to a specified pitch.

The staff position setting circuit 32 supplies staff position designation data ST to the pitch data generation circuit 30 when the position of a particular staff on the musical score sheet 20 is designated. In this case, to specify the staff position, for example, after placing the music sheet 20 in the music sheet placement area 22, use the input pen 12 to select the left end of the uppermost line and the right end of the lowermost line on a specific staff. This can be carried out by sequentially pressing the buttons and turning on an initial setting switch (not shown) each time the buttons are pressed. Pitch data generation circuit 3
When 0 receives the staff position specification data ST, it generates pitch data for the specified staff based on this.
PD begins to occur. Note that if a predetermined staff position is set in advance in the music score sheet arrangement area 22 and a standardized music score sheet that matches this staff position is used,
The staff position setting circuit 32 can also be omitted.

The note length data generation circuit 34 is, for example, a ROM.
(read-only memory)
Note length data LD corresponding to a specified note length or rest length is generated based on switch operation information from a note length designation switch 26A including the note length designation switch 26 and shift switch 28 mentioned above.

When inputting musical note information, after placing the musical score sheet 20 in the musical score sheet arrangement area 22 and specifying the position of a specific staff, the input pen 12 is used to input the pitch of an arbitrary note on the musical staff. Specify the position by pressing. Then, simultaneously with or after such pitch designation operation, the note length is designated by the note length designation switch 26. As a result, the pitch data generation circuit 30
From is the pitch data PD corresponding to the specified pitch,
The note length data generation circuit 34 generates note length data LD corresponding to the specified note length.

Based on the pitch designation operation, the pitch input board 10 sends out a pen-on signal PON="1" indicating that the pen has been pressed, making the AND gate 36 conductive. Also,
Based on the code length designation operation, the OR gate 38 receives the signals of each bit of the code length data LD and generates an output signal "1". This output signal "1" is supplied to the write control circuit 42 via the AND gate 36 and further via the OR gate 40, and in response, the write control circuit 42 outputs a write command signal WR and a write address signal. ADS is supplied to data memory 44.

The data memory 44 consists of a RAM (random access memory), which stores pitch data PD corresponding to a specified pitch and a specified pitch data PD in response to a write command signal WR and a write address signal ADS. Note length data LD corresponding to the note length is written.

When entering rest information, use input pen 1.
A desired rest length is designated by the note length designation switch 26 without pressing 2 anywhere. That is, among the four note length designation switches 26, for example, if the user wants to designate the length of a quarter note, he turns on the switch corresponding to a quarter note. As a result, the note length data generation circuit 34 outputs note length data LD corresponding to the designated rest length, and in response, the OR gate 38 generates an output signal "1". At this time, the pen-on signal PON
is "0", so the inverter 46 generates an output signal "1" and makes the AND gate 48 conductive. Therefore, the output signal of OR gate 38 is “1”
is passed through AND gate 48 and further through OR gate 4
0 to the write control circuit 42, and in response, the write control circuit 42 generates a write command signal WR and a write address signal ADS.

Therefore, the data memory 44 stores pitch data PD with all bits "0" and note length data LD corresponding to the specified rest length in accordance with the write command signal WR and write address signal ADS at this time. is written.

Pitch and note length data for one song can be written into the data memory 44 in the same manner as described above. After this writing process is completed,
By appropriately reading pitch and note length data from the data memory 44, musical tone generation, key press position display, musical score display, musical score printing, etc. can be automatically performed.

In addition, in the above embodiment, the musical score sheet arrangement area 2
Although the music information input operation is performed by placing a musical score sheet in 2, it is preferable to write a musical staff in advance in the area 22 and specify a desired pitch position with respect to this musical staff by pressing with the input pen 12. Therefore, input operations may be performed without placing a musical score sheet on the area 22. In addition, the position specified by the input pen is detected using a pressure-sensitive element, which is based on the capacitive coupling between the input pen and the pitch input board.
This may be done using electromagnetic coupling, optical coupling, or the like.

[Effect of idea]

As described above, according to this invention, the pitch position is specified using the input pen on the pitch input board, and the note length or rest length is specified using the note length specification switch provided on the input pen. , which allows input operations to be performed easily and accurately with only one hand by placing a musical score sheet on the pitch input board, and even non-skilled users can perform input operations efficiently. It is.
