Abstract

PURPOSE:To assign the best range to a playing operating element by setting the range of a scale to be assigned to plural operating elements and setting operation elements which are not used according to the scale. CONSTITUTION:It is judged which pad 2 is struck and which scale setting switch is pressed and when it is judged that the pad number of the struck pad 2 is odd and the pad is a 1st pad, a note number(NN) corresponding to the address of a RAM 9 for the struck pad 2 is written together with NNs before and after it, thus completing a 1st node table(NT). Then NNs corresponding to addresses before and after it are written to generate a 2nd NT. When the pad 2 is struck and the scale setting switch is not pressed, on the other hand, the NN is read out, the value K of the attached buffer of a CPU 6 is added to the NN, and an NN corresponding to the on-off state of an octave switch is outputted from an output part 8.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention outputs musical performance information in high pitch by operating operators arranged in a keyboard shape, such as pressing keys or hitting keys. The present invention relates to a performance device for an electronic musical instrument.

[Prior Art] There is an electronic percussion instrument as a type of electronic musical instrument.Such electronic percussion instruments have a plurality of keys arranged in the shape of a percussion surface, and musical tones corresponding to multiple note names can be generated by percussion operations similar to those of a syllable. There is a method that can selectively generate (see Japanese Patent Laid-Open No. 61-239299).

[Problems to be Solved by the Invention] In the conventional electronic percussion instruments as described above, the range assigned to each keyboard-shaped hitting surface is constant, and this range cannot be changed arbitrarily. There are also instruments that allow you to change the range, but this can only be done in octaves. Therefore, in such an electronic percussion instrument, it is not possible to allocate an optimal range to each striking surface depending on the piece of music being played.

SUMMARY OF THE INVENTION An object of the present invention is to provide a performance device for an electronic musical instrument that can allocate an optimal range to a performance operator such as a striking surface depending on the piece of music to be played.

[Means and operations for solving the problem] In order to solve the above problems, in the first invention, the keyboard is arranged like a keyboard,
A plurality of controls for specifying pitches, means for setting a range of scales to be assigned to these plurality of controls, and means for setting the above-mentioned controls that are not used according to the scale set by the setting means. , is equipped.

According to the first invention, when the performer sets the scale range using the scale range setting means, the operators that are not used are set according to the set scale. It can be an array of manipulators. Furthermore, when the scale range is changed, the operators are arranged in accordance with the changed scale range. Therefore, the playable range can be expanded without increasing the number of operators.

In the case of the first invention, there are operators that are not used, but there is a risk that the performer will not be able to clearly identify which operators are not used. Therefore, in the second aspect of the invention, a display means is provided that can distinguish between unused operators and used operators.

By providing this display means, it is possible to visually confirm which operators are not in use.

Further, in the first or second invention, unused operators are left as they are, but in the third invention, functions other than pitch specification are assigned to unused operators. Thereby, the performance effect of the electronic musical instrument can be enhanced.

[Embodiment] Hereinafter, the present invention will be described in detail based on an embodiment shown in FIGS. 1 to 7, in which the present invention is implemented in an electronic percussion instrument. The electronic percussion instrument of this embodiment has an operator, for example, a pad 2, as shown in FIG. This pad 2 consists of eight first butts 21 and seven second butts 22, and the first pads 21 are arranged in a line at predetermined intervals. Also,
The second pads 22 are arranged in a line between the first pads 21. That is, the first pad 21 and the second pad 22 are arranged like a keyboard. These first pads 21 are assigned odd pad numbers in order from the left end in FIG. 6, and even pad numbers are assigned to the second pads 22 in order from the left end in FIG. That is, the first putt 21. The bad numbers of the second pad 22 and the first pad 21 increase in order from the first pad 21 at the left end in FIG. The first and second pads 21 and 22 are each made of a transparent sheet, as shown in FIG. 7, and a sensor 3 for detecting impact is provided at the bottom thereof.

These sensors 3 consist of an upper transparent pressure-sensitive rubber 31 and a lower transparent pressure-sensitive rubber 32 that are provided at intervals in the vertical direction. For example, when the bat 2 is hit by a stick or a mallet, the upper transparent pressure-sensitive rubber The rubber 31 flexes downward and comes into contact with the lower transparent pressure sensitive rubber 32. This will cause bad 2
is detected to have been hit. Note that 33 is a spacer for maintaining the distance between the upper transparent pressure-sensitive rubber 31 and the lower transparent pressure-sensitive rubber 32, and 34 is a spacer for insulating the lower transparent pressure-sensitive rubber 32 from the components below it. It is a transparent insulator.

In each of the second butts 22, a display means, for example, a liquid crystal display section 4, is provided below the transparent insulator 34 of the sensor 3 provided therebelow. Note that 41 is the chassis of this electronic percussion instrument.

In addition, a switch 5 is provided as shown in FIG. The switch 5 includes a scale setting switch 51, an octave up switch 52, and an octave down switch 53. The scale setting switch 51 is
The octave up switch 52 is operated when assigning a note number according to the MIDI standard to the octave up switch 52. This is used to set the note number one year higher than the note number assigned to Bad 2.
The octave down switch 53 is operated to set the note number output from the output unit 8 when the bad 2 is struck to a note number that is one octave lower than the note number of the struck bad 2. . Although not shown in FIG. 6 (see FIG. 5), a footswitch 54 is also provided. This foot switch 54 is operated to raise the note number output from the output section 8 by half an octave when the putt 2 is hit.

As shown in FIG. 5, the information from each sensor 3, the switch 5, and the foot switch 54 are as follows.

It is input to the CPU 6. The CPU 6 sends this information to the RO
Process according to the control program stored in M7,
The note number is stored in the address corresponding to the bad number of each pad 2 in the storage area provided in the RAM 9, the liquid crystal display section 4 provided in the second pad 22 that is not assigned at this time is changed in color, and the A MIDI signal such as a note number corresponding to the selected bad 2 is outputted from the output section 8 to a sound source section (not shown).

Note that the CPU 6 is equipped with various registers, buffers, timers, etc. used to perform the above-described processing.

In addition to the control program, the ROMT stores a table as shown in FIG. 3 in which each note name is associated with a note number according to the MIDI standard and stored in the order of pitch. In this table, the car has a null (Ntl
LL) portion is provided. This is due to the following reasons. As shown in FIG. 6, since the second pad 22 is provided between each of the first pads 21, that is, if the pad numbers of the first and second pads 21 and 22 are the most different, Since the first pad 21 and the second pad 22 are arranged so that they are assigned pitches that differ by a semitone, the table in ROM 7 corresponds to this by sequentially arranging note numbers for pitches that differ by a semitone. has been done. However, between the E and F notes, and between the B and C notes,
Each note must differ in pitch by a semitone.

However, as will be described later, when a specific note number is assigned to the first pad 21, note numbers are automatically assigned to each of the pads 2 before and after it, and if a null part is not provided, for example When assigned to the first pad 21, which contains the E note, the adjacent first pad
F note should be assigned to pad 21, but F
The sound will be assigned to the adjacent second band 22.

To prevent this, a null portion is provided.

Using this table, RAMQ
Note numbers are written in the atres and slots corresponding to the pad numbers of each pad 2 in the storage area provided therein, forming a note table. In this embodiment, two storage areas, a first and a second storage area, are provided. In this embodiment, each note number in the note table in the second storage area is half an octave higher than each note number in the note table in the first area.

An outline of the processing performed by the CPU 6 is as follows. While pressing the scale setting switch 51, press the first pad 2.
When you hit any one of 1, note number 60 (note name C4) is written in the address corresponding to the pad number of bat 2 that was hit in the first area of RAM 9, and note number 60 is written in a total of 14 addresses before and after that. Write the 14 note numbers before and after. Also, write note number 65 (note name F4) in the address corresponding to the putt number of bat 2 that was hit in the second area, and write the note number 1 before and after note number 65 in a total of 14 addresses before and after that.
As a result of writing four note numbers in the first area, the liquid crystal display section 4 (
The hatched area in Figure 6) has changed color, and this second
It is displayed that the pad 22 is not used for performance. Then, for playing, the first or second pad 21.22
When you hit the pad 2 of the note table in the first area, the note number assigned to the hit pad 2 is output to the output section 8.
is output from. In addition, the octave up switch 52
If a strike is made with is pressed, a note number that is l octave higher than the note number assigned to the struck Bad 2, that is, a value 12 larger as is clear from Fig. 4, is output. When a ball is hit while the octave down switch 53 is pressed, a note number that is one octave lower than the note number assigned to the hit putt 2, that is, a value smaller by 12, is output. Also, foot switch 5
4 is pressed and a strike is made, a note number that is half an octave higher than the note number assigned to the struck bat 2, that is, a note number stored in the second area is read out from the output section 8. It will be done.

1 and 2 are flowcharts of the operations described above, and FIG. 1 is a subroutine for setting a musical scale and outputting a note number. This subroutine is executed at regular intervals, and first, it is determined whether any putt 2 has been hit (step Sl).
, if the answer is NO, end this subroutine,
If the answer to step SL is YES, the scale setting switch
It is determined whether the button 51 is pressed (step S2).

If the answer is YES, it is determined whether the pad number of the putt 2 that was hit is an odd number, that is, whether it is the first pad 21 (step S3). If the answer is No, the bat 2 that was hit is the second note (22) and note number 60, C4, cannot be assigned, so this subroutine ends.Also, if the answer to step S3 is If YES, the pad 2 that was hit is the first bat 21, so the note number 6 of 04 is stored in the address corresponding to the pad 2 that was hit in the first area of the RAM 9.
Write 0 and write note number 6 to the addresses before and after it.
Write note numbers around 0 to form a first note table, and write note number 65 of F4 to the address corresponding to the hit bad 2 in the second area of RAM9.
Write the note number 65 in the addresses before and after it.
Write the note numbers before and after to form a second note table (step S4), this step 4 or
This applies to the scale range setting means and the unused operator setting means.

FIG. 4 shows the first and second note tables formed in the RAM 9 when the first bat 21 with bat number l is hit. Following step S4, the note table in the first storage area is read, and the second note table 22 of the bad number in which the null part is stored is read.
The color of the liquid crystal display section 4 is changed (step S5), and this subroutine is ended. By changing the color, the second
This indicates that a note number is not assigned to bat 22.

On the other hand, if the answer to step S2 is NO, that is, if putt 2 has been hit but the scale setting switch 51 has not been pressed, then it is a performance, and the hitted pad on the note table that has been read is played. 2's note number is read out (step S6). Note that if null is assigned to the bat 2 that was hit, the note number will naturally not be read out, and the note number attached to the CPU 6 will be read out. Add the buffer value K (
Step S7). Although not shown in the flowchart, the value of this buffer includes the octave up switch 52
When the octave down switch is pressed, it is set to +12, and when the octave down switch 5 is pressed, it is set to -12.
When both the octave up switch 52 and the octave down switch 53 are not pressed, the state is O. Therefore, when the octave up switch 52 is pressed, the note number will be one octave higher than the pad 2 that was hit, and when the octave down switch 53 is pressed, the note number will be one octave higher than the pad 2 that was hit.
It is said to be a note number that is one octave lower than . Then, such a note number is outputted from the output section 8 (step S8), and this subroutine is ended.

FIG. 2 is a flowchart showing a subroutine that operates when the foot switch 54 is operated. First, it is determined whether the foot switch 54 is pressed (step 5I).
O) If the answer is No, this subroutine is ended, and if the answer is YES, the note number table in the second storage area is read (step 512). Next, the liquid crystal display section 4 of the pad 2 corresponding to the null part of the read note number table changes color, and the second
In the storage area, the second pad 22 to which no note number is assigned is displayed (step 514), and this subroutine is ended. The reason why the pitch is changed by half an octave in this manner is that it is sometimes more convenient for performance to change by half an octave than to change by one octave at a time.

In the above embodiment, by pressing the scale setting switch 51 and hitting the first pad 21 to which the note number of C4 is to be assigned, a note number is assigned to each pad 2, and the desired scale range is assigned. However, by storing in advance in the ROM 7 a large number of tables in which note numbers are assigned to each note 2, that is, note tables with various settings, and by operating the scale setting switch 51. , each table is sequentially read out, and the note table with the desired settings is written into the RAM 9 by stopping the operation of the scale setting switch 51 after the note table with the desired settings has been read out. Good. In this case, either provide a display means to display which setting of the note table is currently being read out, or display the liquid crystal display section 4 of the second pad 22 that is not used for the note table of the setting that is being read out.
It is desirable to change color. Further, in the above embodiment, the foot switch 54 is provided to read out a note number half an octave higher than the struck pad 2, but in some cases, such a structure may not be necessary. Furthermore, when the foot switch 54 is operated, it may be configured to output a note number half an octave lower.
Although the liquid crystal display section 4 provided on the pad 2 to which no note number is assigned is changed in color, the liquid crystal display section 4 provided on the second pad 22 to which a note number is assigned may be changed in color. Furthermore, instead of the liquid crystal display section 4, as shown in FIG.
You may provide display means such as the following. In this case, the L E D 4a on the side of the pad 2 to which no note number has been assigned may be lit, or conversely, the L E D4a on the side of the pad 2 to which a note number has been assigned may be lit.
D 4a may be lit. It is also possible to assign functions other than pitch specification to the pad 2 to which no note number has been assigned. For example, you can set a tone different from the tone currently being played to further enhance the performance effect. In the above embodiment, the present invention was applied to an electronic percussion instrument, but it can also be applied to an electronic musical instrument equipped with a keyboard-like operator.

[Effects of the Invention] As described above, according to the present invention, when a performer sets an arbitrary range range using the range setting means, the operators can be arranged in accordance with the set range. can. Furthermore, when the range is changed, the controls are arranged in accordance with the changed range. Therefore, it is possible to allocate the optimum range to the operator depending on the piece of music to be played. Further, since a display means is provided that can distinguish between unused operators and used operators, it is possible to visually confirm which operators are not used. In addition, functions other than pitch specification are assigned to unused controls. Thereby, for example, the performance effect of the electronic musical instrument can be enhanced.
