Abstract

PURPOSE:To enable a player to play an electronic wind instrument whichever fingering of wind instruments the player masters by constituting the electronic wind instrument so that the player can freely set fingering. CONSTITUTION:A CPU 4 discriminates whether a dip switch 24 selects the setting mode or the playing mode. When the setting mode and the monotony mode are selected, corresponding pitch data is written in a register provided in the CPU 4 or a RAM 8. For example, only a note key switch 221 is depressed in case of a tone B. Meanwhile, when the compound sound mode is set, tones C and B are assigned to note key switches 221 and 222 respectively. When the monotony mode and the playing mode are selected, the CPU 4 reads out pitch information of the tone A from a monotony mode memory at the time of depression of keys 221 and 222. When the compound sound mode and the playing mode are selected, pitch information of tones C, E, and G and the flatted tone B are read out from a compound sound mode memory at the time of simultaneous operation of note key switches 221, 225, 228, and 2211.

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an electronic wind instrument that electronically generates musical tones by operating a key switch provided on a wind instrument-like body.

<Prior art> Conventionally, as the above-mentioned electronic wind instrument, for example,
There is something like the one disclosed in Japanese Patent No. 24311.

This system is equipped with a musical tone generation circuit that electronically generates musical tones by operating multiple key switches provided on the main body of a wind instrument. A selection circuit that generates a fingering method is provided for each different fingering method, and a fingering selection circuit that operates one of these selection circuits is provided.

<Problem to be Solved by the Invention> Such an electronic wind instrument can be played using any of a plurality of fingering methods, so if the player selects the fingering method that he or she has mastered using the fingering selection circuit, It is possible to perform using the fingering method that the performer has mastered. However, there are many types of wind instruments, such as the flute, saxophone, and clarinet, and each type has a different fingering method. Therefore,
The above configuration has the problem that a large number of selection circuits are required to enable a player who has mastered any fingering method for each wind instrument to perform.

However, when playing an electronic wind instrument such as the one described above, if a performer can perform using the one fingering method that he or she has mastered, there is almost no need to use other fingering methods.

In view of the above-mentioned points, an object of the present invention is to provide an electronic musical instrument that is configured so that the player can freely set the fingering method, and eliminates the need to provide selection circuits corresponding to a plurality of fingering methods. shall be.

Means for Solving the Problems> A first invention includes a plurality of key switches provided in a control section shaped like a wind instrument, and a detection means for detecting the operation states of these key switches and generating operation information. , means for generating pitch information specifying a pitch, mode selection means for selecting either a storage mode or a performance mode, and storing the operation information and the pitch information in correspondence in the storage mode. and means for reading pitch information corresponding to the one-note operation information from the storage means and generating a musical tone signal in the performance mode.

The second invention, like the first invention, includes a plurality of key switches and a detection means, and further associates operation information obtained from the operation states of the plurality of keys with one piece of pitch information. A single note mode key memory stores a plurality of keys, a multiple note mode key memory stores a plurality of pieces of operation information obtained from the operating state of one key and one pitch information in correspondence, and a single note mode and a double note mode. mode selection means for selecting one of the modes, and means for reading pitch information corresponding to the operation information obtained by the detection means from the key memory corresponding to the selected mode and generating a musical tone signal. It is something.

<Operation> According to the first invention, when the mode selection means selects the storage mode and the player operates the key switch in accordance with the fingering technique he/she has mastered, the detection means generates one piece of operation information. Further, when the pitch specifying means is operated in correspondence with this =II4=one operation information, pitch information is obtained. These operation information and pitch information are stored in the storage means in correspondence with each other.

When a performance mode is set by the mode selection means and a key switch is operated, the detection means generates one operation information corresponding to the operation of the key switch, and pitch information corresponding to this operation information is read out from the storage means, A musical tone is generated based on this pitch information.

In the second invention, when the mode selection means selects the I'li child mode and operates a plurality of key switches at the same time,
At that time, pitch information corresponding to one piece of operation information detected by the detection means is read out from the single note mode key memory, and a single note musical tone is generated based on this pitch information.

Furthermore, when the mode selection means selects the double note mode and operates a plurality of key switches, the detection means generates a plurality of operation information corresponding to each operated key, and pitch information corresponding to each of these plurality of operation information. and multiple tone mode key memory, and musical tones are generated based on each of these pitch information. In other words, double tones are generated.

<Example> As shown in FIG.
O, parallel/serial converter 12, musical tone generating means 14
, an amplifier 16 and a speaker 18.

As shown in detail in FIGS. 4 and 5, this control unit 2 has a mouthpiece 20 at one end for blowing air into it, and this mouthpiece 20 has a sensor (not shown) that detects the strength of the breath. ) is provided. This sensor generates breath strength detection information, and upon receiving this detection and information, the musical tone generating means 14 controls the volume of the musical tone to be generated.

As shown in FIG. 4, on the upper surface side of the control section 2, twelve note key switches 22I to 22.2 are provided along its length.

As shown in FIG. 5, a dip switch 24 is provided approximately at the center of the lower surface of the control section 2. This dip switch 24 is for generating information for switching between a performance mode and a setting mode. The performance mode means that by operating the note key switch 22, 22, 2, the musical tone generating means 14 generates a musical tone corresponding to the operation.
The setting mode is a mode in which pitch information is stored in the RAM 8 in correspondence with the operating state of the note key switch 22 or 22,2.

In addition, as shown in FIG. 4, note key switches 22,
An assign mode key switch 26 is provided near the. This assignment mode key switch 26 generates information for switching between single note mode and double note mode. Single note mode means note key switch 22.
This is a mode in which one note pitch can be set or played when a plurality of the note key switches 221 to 22.2 are operated. This mode allows you to set or play a single pitch. Therefore, if the multiple note mode and the performance mode are operated and a plurality of note key switches 221 to 22.2 are operated, a plurality of musical tones will be generated simultaneously.

Furthermore, program change (amp/down) switches 28 and 29 are provided near the dip switch 24. The program change (up/down) switches 28 and 29 generate program change (timbre designation) information in the performance mode, and generate pitch designation information in the setting mode.

Further, as shown in FIG. 4, a modulation button 30 is provided near the note key switch 221. This modulation button 30 is connected to a pressure sensor (
(not shown), this pressure sensor detects the pressure of pressing the modulation button 3G, and generates modulation information in response to this detected pressure. The musical tone generating means 14 receives this information and controls the depth of modulation such as vibrato and tremolo.

There are various other switches provided on the bottom side of the control unit 2, but since they are not directly related to the present invention, their explanations will be omitted.

In the setting mode, the foot switch 3 is set to the note key switch 22. 〜22、2 Operation information and up・
The pitch information from the down switches 28 and 29 is stored in the RAM.
This is for generating command information to be stored in the 8.

The CPU 4 scans each switch of the control unit 2 and the foot switch 3 according to a program stored in the ROM 8 to detect the operation state, and performs processing based on the information obtained by this detection. This process will be described later.

As shown in FIG. 3, within the RAMB, a key memory area 32 is provided for storing pitch information corresponding to the fingering method of the note key switches 221 to 22.2. This key memory area 32 consists of a single note mode key memory 32a for storing pitch information in single note mode and a double note mode key memory 32b. In single note mode, note key switch 22. There are a total of 12 note key switches 22 to 221□. There are 2'2 (=4096) operation states. All these note key switches 221 to 22□2
The single note mode key memory 8a has 4,096 areas so that pitch information can be stored in accordance with the operating state of the key. Also, in double note mode, note key switch 2
2. to 22. Since l pitch information is associated with each note key switch 22 . It has a total of 12 areas corresponding to each of 22.2 to 22.2. For example, note key switch 22 corresponds to address O, note key switch 22□ corresponds to address l, etc.
Address 11 corresponds to note key switch 22,2.

Note that this RAM 8 is preferably backed up by a battery or has a configuration in which the stored contents are not erased even when the power is turned off.

Processing by the CPU 4 will be explained. The CPU 4 determines whether the assignment mode key switch 26 is selecting the single note mode or the multiple note mode. Then, it is determined whether the dip switch 24 is selecting the setting mode or the performance mode. Assuming that we are currently in the single note mode and setting mode, as shown in FIG. ). Then, it is determined whether the dip switch 24 is off, that is, whether it is in the performance mode (step S
4). If the answer is YES, the setting mode is ended. If the answer is No, the up/down switch 28
．． In step S6), the up switch 2 of the up/down switches 28 and 29 is pressed.
If 8 is pressed, the value of the register is increased by 1 (corresponding to a semitone in pitch data) (step S8).

Further, if the down switch 29 of the up/down switches 28 and 29 is pressed, the value of the register R is decreased by 1 (step 510). Then, the value of register R at that time is displayed on the display device 10 (step 5
12). Note that if the up/down switch 28 is not pressed, the value of the register at that time is displayed as is on the display device IO. Then, it is determined whether foot switch 3 is pressed and turned on (step S
14). If it is not on, the process returns to step S4. Therefore, as long as the foot switch 3 is not turned on, the contents of the register can be changed arbitrarily by the up/down switches 28 and 29. Also, if it is on, the note key switch 221 to 22□2 at that time
The operating state of is read (step 5I6). Then, read note key switch 22. Write the pitch information of the register B to the address of the single note mode key memory 32a corresponding to the operating state of 22.2/(Step S1
8), return to step 2.

For example, if settings are made according to an example of standard fingering for a wind instrument shown in FIG. 6, as is clear from the figure, only the note key switch 221 will be pressed for the B note, for example. Therefore, the up/down switch 28.29 is 1 display device 1
0 until the B sound is displayed, then operate the note key switch 221, and then operate the foot switch 3, the note key switch 22. The data obtained by the operation of the lowest bit (LSB), note key switch 2
If the data obtained in 2.2 is the most significant bit (MSB), the note key switch 22. Since the operation information obtained by operating only the note B is 1, the pitch information of the B note is stored at address l of the single note mode key memory 32a, as shown in FIG. Similarly, note A is stored at address 3.

Note that one pitch information can be changed by using the up/down switch 28.
29 to display it on the display Hto, and press note key switch 2.
2. With the operation state consisting of 22.2 to 22.2, the foot switch 3 is operated to switch the note key, - switch 22. Single note key memory 32 determined by the operating state of 22, 2
After storing the above-mentioned pitch information in the address of a, the note key switch 22.a different from the above is stored without changing this pitch information. to 22. When the foot switch 3 is operated in the operation state □, a so-called substitute finger can also be set.

In the case of double-note mode setting, steps S2 to S16 are performed in the same way as in single-note mode setting, but note key switch 22, which is operated prior to step S16, is
．． There is only one key memory 22.2 to 22.2, and the difference is that the key memory stored in step S18 is connected to the multitone mode key memory 32b. Therefore, as shown in FIG. 7, for example, note C note is placed on the note key switch 221, C@ is placed on the note key switch 22□, etc. Note key switch 2
When assigning B note to 212, the settings for C note are as follows:
First, operate the up/down switches 28 and 29, and
Display the sound on the display 2tlO, and press the note key switch 2.
21 and the foot switch 3, the pitch information of the note C is stored at address O of the double note mode key memory 32b, as shown in FIG. Other sounds are set in the same way.

In the case of single note mode and performance mode, for example, the note key switch 22. ．． When 222 is pressed, the CPU 4 reads the pitch information of note A from address 3 of the single note mode key memory 32a. Then, when a breath is blown, volume information is determined according to the strength of the breath. Further, information on the depth of modulation is determined in accordance with the pressure with which the modulation button 30 is pressed. Furthermore, tone color designation information is generated in response to the operation of program change switches 28 and 29. Then, each of these pieces of information is supplied to the musical tone generating means 14 via the parallel/serial converter 12 in MIDI format. The musical tone generating means 14 generates a musical tone based on each of the sent information and supplies it to the amplifier 16, which amplifies the musical tone and supplies it to the speaker 18.

In the case of double note mode and performance mode, for example, the note key switch 22. ．． 22. ．． 22. ．． 221. If you operate simultaneously, address 0. of the multitone mode key memory 32b.
Pitch information of C, E, G, and Bb is read from 5.8.11. Therefore, a C7 chord can be generated.

Similarly, note key switches 223.226.22. .

When are operated simultaneously, the pitch information of F and A is read from address 3.6, IO of the multitone mode key memory 32b, and the chord of D is generated.

Note that other information such as volume information and timbre designation information is supplied to the musical tone generating means 14 in the same manner as in the single note mode.

In the above embodiment, the standard fingering method for the single note mode shown in FIG. 6 and the standard fingering method for the compound note mode shown in FIG. 7 are stored in the single note mode key memory 32a and the compound note mode key memory 32b, respectively. I explained the case,
When this electronic wind instrument is actually commercially available, the standard fingering method for the single note mode shown in Figure 6 and the standard fingering method for the double note mode shown in Figure 7 are preset in ROM6 and RAM8, so that the performer can perform both of the above methods. If you want to play with a different fingering method, change the fingering method using the setting mode. Further, in the above embodiment, the up/down switch 28.2
The configuration was configured so that the value of register R increases or decreases by a semitone each time 9 is pressed, or the value of register R increases or decreases rapidly while the up/down switch 28.29 is pressed. may be configured.

<Effects of the Invention> As described above, according to the first invention, the player can freely set the fingering method, so if the player has already mastered the fingering method, it is easy for the player to change the fingering method. Once set, there is no need to learn new fingering methods. In addition, it is easier for the manufacturer to manufacture the product, and costs can be reduced.

Furthermore, according to the second invention, it is possible to play not only single notes but also compound notes that cannot be played with natural wind instruments, so it is possible to perform performances that cannot be performed with natural wind instruments.
